Versatile communications connectors

An apparatus for conveying signals between a communications card and a signal utilization device or network. In one form (FIGS. 1,2), structures are provided for receiving an RJ series plug and for making electrical connection with at the contacts on the plug and conveying any signals on the contacts to a communications device such as a telephone, facsimile machine, modem, or a local area network adapter. A body (102) includes one or more recesses (106) which receive the plug. An expandable and stretchable membrane (114) isolates the contacts in the plug from electrical contact with an object in a surrounding environment such that passage of current from one or more of the electrical contacts to an object present in the surrounding environment is prevented. Also provided (FIGS. 7, 14) is a replaceable direct access arrangement (151, 258) which is replaceably held within the communications device (150, 250). Both the structures providing the receptacles and the direct access arrangement are easily removable in case of damage or if other functions are desired. The replaceable direct access arrangement allows operation in countries having different telecommunications standards and allows operation with many different communications devices. Wireless communication is also provided.

BACKGROUND

1. The Field of the Invention

This invention relates to electronic communication devices. More particularly, the present invention relates to connectors used to attach a communications line to a computer.

2. The Background Art

Telecommunications services have become an integral part of modern society. The number of telephones in the United States alone exceeds 150 million. Moreover, communications within an organization between people and machines further increases the size of the communications network. The vast majority of the communications devices now in use require a wired connection to a communications line. Such communications devices include, for example, telephones, facsimile machines, modems, and local area network (LAN) adapters. Wireless communications, however, are becoming more commonplace in many instances.

In order to conveniently attach a communications line to a communications device, standard connectors have been promulgated. The most popular of these connectors is known in the art as the RJ-xx series of connectors. Of the RJ-xx series of connectors, the RJ-11, RJ-12, and RJ-45 connectors are widely used. The RJ-11 connector comprises a six contact plug and a corresponding jack which is standardized in the industrialized world. The conventional six contact RJ-11 connector has the desirable attributes of having both low cost and high reliability.

The RJ-xx series of connectors, mostly the RJ-11 connector, is commonly used to attach a communications device such as a telephone, facsimile machine, or a modem (all of which may be integrated into a single device) to a communications line. Such devices are becoming smaller, so small that one or more dimensions of the customary RJ-11 jack, also referred to as a receptacle, is larger than a corresponding dimension of communications device. For example, communication devices which comply with the Personal Computer Memory Card International Association (PCMCIA), also referred to as PC Card, standards have dimensions of about 2.1 inches by about 3.4 inches with a thickness of only 3.5 mm, 5 mm, 8 mm, or 10.5 mm. Such small communications devices cannot incorporate customary RJ-xx series receptacles but still require compatibility with RJ-xx series plugs in order to attach to a communications line.

U.S. Pat. No. 5,183,404 to Aldous provides several schemes for providing a miniature RJ-11 compatible receptacle. Disadvantageously, many of the schemes set forth in Aldous leave the electrical contacts exposed to the surrounding environment. Thus, a user may come in contact with the electrical contacts of the plug, which in the U.S. may carry more than 80 volts. Further, since the contacts of the RJ-11 plug are exposed, the contacts may be inadvertently shorted together. Thus, the scheme included in the Aldous reference presents a danger of electrical shock and electrical short circuit. Moreover, some of the receptacle schemes disclosed in the Aldous reference are particularly prone to breakage and damage because of inherently weak structures.

Thus, it would be an advance in the art to provide a miniaturized communications connector which overcomes these drawbacks.

BRIEF SUMMARY AND OBJECTS OF THE INVENTION

In view of the above described state of the art, the present invention seeks to realize the following objects and advantages.

It is a primary object of the present invention to provide a communications line receptacle for use with a miniaturized communications device wherein the electrical contacts are shielded or isolated from the surrounding environment.

It is also an object of the present invention to provide a miniaturized communications line connector which is resistant to breakage and which can be stored out of the way when not being used.

It is a further object of the present invention to provide a communications line receptacle which is readily replaceable if broken.

It is another object of the present invention to provide a communications card which can be readily adapted to meet various communications standards.

It is a further object of the present invention to provide a communications card which can provide wireless communications.

These and other objects and advantages of the invention will become more fully apparent from the description and claims which follow, or may be learned by the practice of the invention.

The present invention provides an apparatus for receiving an RJ-xx series plug and making electrical connection with at least two conductors on the plug and conveying any signals on the conductors to a communications device such as a telephone, facsimile machine, modem, local area network adapter, or some other device.

The apparatus includes a body, also referred to as a body means. A recess, or recess means, is provided on the body. In some embodiments the recess means preferably includes an open first end and a closed second end. In other embodiments, the recess means preferably includes open first and second ends. The recess means preferably has dimensions such that the plug is closely received therein. A means is also provided for releasably engaging the plug such that the plug is releasably held in the recess.

At least first and second electrical conductors are provided in the recess. Each of the electrical conductors are positioned such that they have electrical continuity with the electrical contacts in the plug when the plug is received into the recess. A means for conveying any electrical signal present on the electrical contacts to the communications device is also provided.

A replaceable direct access arrangement unit allows the communications card to be interfaced with telephone systems, or other communications systems, which may each require adherence to a different standard. When necessary, a user merely replaces an existing direct access arrangement unit with another direct access arrangement unit which is compatible with the wired telephone system or the wireless communications system that is available to the user.

Also preferably included with the recess means is an expandable means for isolating the contacts in the plug from electrical continuity with an object in a surrounding environment such that passage of current from one or more of the electrical contacts to an object present in the surrounding environment is prevented. The expandable means is located at the second end of the recess and is preferably a stretchable membrane. The expandable means expands to accommodate a plug received in the recess and tends to return, and can be returned by a user, to a position within the thickness of the body when not being used so the apparatus assumes a compact configuration.

Embodiments of the present invention include receptacle modules which receive an RJ-xx series plug. One preferred embodiment of the present invention includes a means for holding the body which receives the RJ-xx series plug. The means for holding the receptacle body or the receptacle module can be easily installed in and removed from the communications device by the user. The present invention allows the body to be retracted into and extended from the communications device while still allowing easy removal and replacement of the body making up the receptacle module. Another preferred embodiment of the present invention includes means for pivotally rotating the body into and out of the communications device such that the body is substantially entirely within the communications device when not being used and the body is rotated to a position where the recess which receives the plug is accessible to the user when desired.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Reference will now be made to the drawings wherein like structures will be provided with like reference designations.

U.S. patent application Ser. No. 08/799,799, filed Feb. 13, 1997 and Ser. No. 08/971,501, filed Nov. 17, 1998, both of which are now incorporated by reference herein in their entireties.

As is evident to those skilled in the art, advances in technology are allowing many different electrical devices to be made smaller than was contemplated just a few years ago. Represented inFIG. 1is a partial perspective view of a lap top computer8. In order to meet the demand for devices utilized with such lap top computers without adding any significant weight or bulk, devices such as a modem card118(shown partially withdrawn from the lap top computer8) which complies with the PCMCIA (also known as PC Card) standards have been produced. Significantly, while most lap top computers are generally note book size (about 8.5 inches by 11 inches) or smaller, the need for further miniaturization of devices such as the modem card118will increase as computing devices of all kinds continue to shrink.

The lap top computer8represented inFIG. 1includes a PCMCIA compliant socket124. The Personal Computer Memory Card International Association (PCMCIA) promulgates the PCMCIA standard which has gained wide acceptance in the industry. It is preferred that the PCMCIA compliant socket adhere to PCMCIA standard pertaining to Type I, Type II, and Type III cards. The preferred standards specify the physical, electrical, and environmental parameters which compliant devices must meet. The system and method of the present invention described herein are preferably compatible with the PCMCIA Card Services Specification 2.1 and Card Services Specification 2.1 as well. This standard and the accompanying specifications are well-known in the art and PCMCIA release2.1, PCMCIA Card Services Specification 2.1, and Card Services Specification 2.1, PCMCIA Standard Release2.1, and all releases promulgated thereafter (including the PC Card standard (1995)), are now all incorporated by reference herein in their entireties. It is to be understood that the present invention can be utilized with other PCMCIA specifications and standards which are now available or which become available in the future as well as with other similarly instructive standards which are now available in the industry or which become available in the future. Examples of such other specifications and standards include the CardBus PC Card standard which is also now incorporated by reference in its entirety. Further information regarding the implementation of these standards can be obtained from the publication Anderson, D. & Shanley, T., CardBus System Architecture (1996) (published by Addison-Wesley Publishing Company) which is also now incorporated herein in its entirety.

The modem card118shown inFIG. 1can also represent numerous other communication devices, for example, a local area network adaptor, voice mail device, telephonic communication device, or a facsimile device. Indeed, with the continuing trend of miniaturizing such devices, all of these devices may be combined into one card the size of the modem card118represented inFIG. 1. All of these devices are examples of those intended to come within the scope of the meaning of the term “communication device” as used herein. Even further, other devices which require communication with one or more additional devices which are now available or which may become available in the future are intended to also come within the meaning of the term communication device as used herein.

As used herein, the term “data utilization device” is intended to include all digital computing devices which are adaptable to receive data or instructions via a communications medium. Perhaps the most common current example of such a device is the personal computer.

A plug, which is compatible with the RJ-xx series industry standard, is indicated generally at10inFIGS. 1,2, and3. The RJ plug10includes a block11which has a first face16into which a plurality of electrical contacts20are recessed. The electrical contacts20are connected to wires (not explicitly represented inFIGS. 1–3) contained within a cable14which lead to the communications network, to another communications device, or some other device. A biased clip12, which is integrally molded as part of the block11, is used to hold the plug10in a corresponding receptacle.

Detailed information regarding the RJ-xx series of connectors can be found in the publication found at Title 47 (Telecommunications), Code of Federal Regulations, Chapter I (Federal Communications Commission), Subchapter B (Common Carrier Services), Part 68 (Connection of Terminal Equipment to the Telephone Network), Subpart F (Connectors), Section 68.500 (1992) which is now incorporated herein by reference in its entirety.

FIGS. 1–3represent a first preferred arrangement of the present invention embodied in a receptacle module generally represented at100. The receptacle module100includes a male coupling112which provides both physical and electrical connections to a corresponding female coupling120provided in the modem card118. It will be appreciated that many different structures available in the industry provide equivalent functions to the male coupling112and the female coupling120.

The receptacle module100includes a body102which can preferably be fabricated from a plastic material using techniques known in the art but can also be fabricated using any suitable materials and techniques now available or which may become available in the future. Two recesses, both of which are generally indicated at106inFIG. 3, are formed in the body102. The inclusion of two recesses106desirably allows accommodation of two communication lines by the receptacle module100.

A cross sectional view of one of the recesses106is provided inFIG. 2.FIG. 2also shows the plug10inserted into the recess106. The recess106has a first open end and a second closed end. When an RJ-xx series plug is inserted into the recess106, a plurality of conductors108communicates with one of its respective contacts20. The conductors108are preferably spring-like so that they are in firm electrical continuity with the contacts20. In some applications only two conductors108are provided while more than two conductors108are provided in other applications. Each of the conductors108is joined to a respective hollow pin, one of which is shown in cross section at110, which mates with corresponding pins provided in the female coupling (120inFIG. 1) It will be appreciated that the number of pins and conductors can be varied in accordance with the particular application for the receptacle block. Moreover, it is within the scope of the present invention to utilize any techniques now available, or which become available in the future, to provide electrical connection between the conductors in the recesses and the coupling structure.

Still referring toFIG. 2, as the plug10is received into the recess, a ledge104provided on the biased clip12engages a ridge18formed on the body102and protrudes into the recess106. The biased clip12and the ledge104cooperate to hold the plug10in the recess106. When removal of the plug10is desired, the biased clip12is compressed and the plug10is removed from the recess106.

Enclosing one end of the recess is an expandable member114. In the embodiment of the invention represented inFIG. 2, the expandable member is an elastic and stretchable membrane. The expandable member114is preferably a rubber-like material which is an electrical insulator. The expandable member114is anchored in a groove116provided in the body102around the recess106.

As clearly shown in the cross section ofFIG. 2, when the plug10is fully inserted into the recess106the expandable member114is moved to expand the depth of the recess106. The expandable member114isolates the contacts20from exposure to the surrounding environment. If the expandable member114were not included, as in the previously available schemes, the contacts20would be exposed to the surrounding environment and the possibility that the contacts20will be shorted together is present. It is also possible that the contacts20could be shorted to an electrical ground, pass a current to a user who touches the contacts20, or some other event might occur which would damage the communications devices attached to the cable14. As known in the art, voltages of more than 70 volts regularly are present on the contacts20when connected to the common carrier telephone network in the United States.

The illustrated expandable member114is preferably fabricated from a rubber-like material which is flexible enough to allow the end of the plug10to expand the flexible member114without undue force being exerted on the plug10. The material from which the expandable member114is fabricated should be strong enough to allow long time use without any failure, e.g., tearing. Those skilled in the art will appreciate that the perimeter of the expandable member114should be securely anchored in the groove116.

It is to be understood that structures other than the expandable member114can function as the expandable means for isolating the contacts20from electrical continuity with any object in the surrounding environment. For example, a combination of rigid panels joined together to allow expansion can function as the expandable means. Further, a combination of rigid elements and elastic elements, or one or more rigid elements which fold within the thickness of the body102, can be devised using the information contained herein. It is preferred that the thickness of the body102be not greater than the thickness of the modem card118. Thus, the expandable member114should tend to automatically return to within the plane of the body102once the plug10is removed and/or allow the user to collapse the expandable member114.

Referring toFIG. 3, it is preferred that the recesses106have particular dimensions. It is preferred that the two unbroken side walls of the recess each have a length in the range from about 0.265 inches to about 0.285 inches and the single remaining straight wall, which is perpendicular to the two side walls, have a dimension in the range from about 0.45 inches to about 0.475 inches for compatibility with RJ-45 plugs. It is also preferred that the two unbroken side walls of the recess have a length in the range from about 0.265 inches to about 0.285 inches and the single remaining straight wall, which is perpendicular to the two side walls, have a dimension in the range from about 0.375 inches to about 0.4 inches for compatibility with RJ-11 and RJ-12 plugs.

FIG. 4is a perspective view of a second embodiment of the present invention with a receptacle module, generally represented at131. The receptacle module131is illustrated inFIG. 4as being retracted into a communications card130. The communications card130can house any of the communications devices indicated earlier.

The receptacle module131includes a body132and a finger pull148formed thereon. The receptacle module131is conveniently kept in its retracted position illustrated inFIG. 4until the communications card130needs to be connected to a communications line (not shown inFIG. 4). When needed, the user grasps the finger pull148and pulls the receptacle module131to its extended position represented inFIG. 5.

FIG. 5illustrates the receptacle modules in its extended position. The receptacle module131includes a pair of ridges (one shown in phantom image at140inFIGS. 4 and 5) which extend from the sides of the receptacle module131and which slide along a pair of grooves, shown best in phantom image inFIG. 5at138.

The receptacle module131includes two recesses, each generally indicated at134, with each recess including a plurality of conductors146. Each recess134also preferably includes an expandable member144which can be identical, similar, or equivalent to the expandable member114discussed in connection withFIGS. 1–3.

FIG. 6is a perspective view of a third embodiment of the present invention including a removable receptacle module generally represented at151. The removable receptacle module151is shown in place in a communications card150as has been explained earlier. The removable receptacle module includes a body166which is illustrated inFIG. 6in a retracted position. It will be appreciated that the retracted position illustrated inFIG. 6can be used or the body166can be fully withdrawn into the communications card150housing. In order to use the apparatus, a user preferably grasps finger grips166and pulls the body166out to an extended position as represented inFIG. 7.

The removable receptacle module151is advantageously easily removable from the communications card150. In order to remove the entire removable receptacle module151from the communications card150, a pair of wings158are squeezed inwardly so a ledge (158inFIG. 8) provided on each wing158disengages from an edge162of the communications card150housing. The entire removable receptacle module151can then be removed from the communications card150. It will be appreciated that other structures can carry out the function of the wings158, as will be explained later in this disclosure.

It is common for a receptacle module, such as receptacle module100, to be broken or damaged during use. If a receptacle module, or other structure providing connection to a communications line is permanently affixed to the communications card or its equivalent, then the only practical recourse is replacement of the entire communications card, even though only the receptacle module has been damaged. The embodiment of the present invention represented inFIGS. 6–9provides that the receptacle module can be easily replaced in case of damage.

Moreover, the removable receptacle module151can be replaced with another removable receptacle module which is adapted to receive another size or style of plug (not represented inFIGS. 6–9). For example, the RJ-11, RJ-12, and RJ-45 connectors have all been generally adopted for specialized applications. Thus, a removable receptacle module adapted for use with RJ-11 plugs can be easily replaced with a removable receptacle module adapted for use with RJ-45 plugs and so forth.

FIGS. 8 and 9provide detailed views of the removable receptacle module151with the body166in an extended and retracted position, respectively. Provided in the body166are a pair of recesses, generally indicated at154, and a plurality of conductors156. Each recess154preferably includes an expandable member, generally indicated at154, as has been previously explained.

As represented inFIGS. 8 and 9, the removable receptacle module151includes a shell168from which the wings156extend and in which the body166slides. It will be appreciated that many different structures can be devised by those skilled in the art to carry out the functions of the shell using the teachings contained herein. Attached to the body166are three guides172which slide within three respective grooves170. The guides172and the grooves172are configured so that the body168is held captive in, i.e., cannot be completely removed from, the shell168. Also represented inFIGS. 8 and 9are a plurality of electrical conductors indicated at brackets174which mate with suitable structures within the communications card150housing to allow transfer of signals between the communications line (not illustrated inFIGS. 8 and 9) and the communications card (150inFIGS. 6 and 7).

It will be appreciated that since the housing168of the receptacle module151is retained within the communications card151, and that the communications card150is held within a lap top computer or a cabinet of some kind, the shell168is protected from breakage and damage so it can be removed without undue difficulty even if damage does occur to other components of the removable receptacle module151.

FIG. 10provides a perspective view of a fourth embodiment of the present invention. The embodiment illustrated inFIG. 10includes a receptacle module, generally indicated at181, illustrated in a retracted position. The receptacle module181includes a body184which is preferably semicircular in shape and rests, when in its retracted position, within a cavity in a communications card180, the cavity being generally indicated at182inFIG. 11. The cavity182is preferably semicircular in shape but can be any shape which provides sufficient room to accommodate the body184in its retracted position.

The body184is attached to the communications card180housing by way of a pivot186. The pivot186allows the body184to be rotated by pulling on a finger grip188to an extended position as illustrated inFIG. 11. In its extended position, the receptacle module181allows access to a recess190which is preferably configured as explained earlier and is ready to receive a plug, such as plug10inFIG. 1. Electrical connections between the conductors (not illustrated) disposed in the recess190and the circuitry contained in the communications card190are provided as can be designed by those skilled in the art. Those skilled in the art can also arrive at numerous structures which are equivalent to those illustrated inFIGS. 10 and 11using the teachings contained herein.

FIG. 12provides a perspective view of a fifth embodiment of the present invention which includes a receptacle module, generally indicated at200, with male couplings204similar to those represented inFIGS. 1–3at112and which are received by a communications card such as those described earlier. A body202is provided with a recess into which the plug10is inserted. As illustrated best in the cross sectional view ofFIG. 13, a plurality of conductors206are provided which communicate with respective contacts20on the plug10.

With the plug10in position on the body202, a lever208holds the plug10in place. The lever208is biased toward the body202by a spring210. A ledge212provided on the lever208engages the ridge (18inFIGS. 2 and 3) provided on the clip12to further hold the plug in place. An aperture is provided on the lever208to accommodate a hump22which is provided on plugs which comply with the RJ-xx series standards. It will be appreciated that the biased lever provides a much more secure and convenient to use apparatus than any of those available in the art which are suitable for use with RJ-xx series plugs and which is suitable for use with miniaturized devices such as the previously described communications cards.

Reference will next be made toFIG. 14.FIG. 14provides a perspective view of a preferred sixth embodiment of the present invention. The embodiment ofFIG. 14provides a communications card250which includes a replaceable direct access arrangement258which is shown ready to be inserted into the communications card250. As is known in the industry, the communications card250makes electrical connection to a computing device via connector sockets, which are represented at252inFIG. 14.

The inclusion of a replaceable direct access arrangement, also referred to as a data access arrangement (abbreviated “DAA”), provides important advantages not previously available in the industry. In the past, DAAs provided a few functions such as: matching the impedances between the telephone line and the modem; receiving data from the telephone line; transmitting data onto the telephone line; providing a pulse dial; and detecting an incoming ring signal. Significantly, different countries and regions of the world require that the DAA carry out different functions.

Presently, it has become practice in the industry to supply a DAA with a modem in accordance with whatever country the user intends to make the connection to a telephone line, i.e., “U.S.” modems are sold in the U.S. and “German” modems are sold in Germany. Since desktop personal computers are very seldom moved from country to country, it has been satisfactory in the past to purchase a modem which can be used in only one country; if the user moved, a new modem was purchased if necessary.

Significantly, the widespread popularity of portable personal computers, and the use of PCMCIA cards in desktop computers, has meant that the computer or the computer peripheral is not bound to any particular location but can travel to any location in the world. Unfortunately, the industry has not recognized, and has not begun to effectively solve, the problems faced by a portable computer user traveling from country to country. Available telephone communication devices are ill suited for use in one or more countries which a user might visit. Even if the desirability of providing a telephone communication device and DAA which is suitable for use in multiple countries was recognized in the industry, the requirements of some countries mandate the use of components which seem too large to allow their incorporation into a communications card which is used with a portable computer.

The present invention solves these problems found in the industry by including a replaceable DAA258which is received into a cavity which is generally indicated at254inFIG. 14. The replaceable DAA258not only can carry out the customary functions already known in the art, but in accordance with the present invention the replaceable DAA258can also carry out other desirable functions as described herein.

The replaceable DAA258preferably makes electrical connection with the communications card250via twenty connector pins256provided in the back of the cavity254and corresponding connector sockets260provided on the rear of the DAA258. As necessary, a user can install an appropriate replaceable DAA258to perform the functions necessary to obtain direct connection to a country's telephone system or to perform some other function.

It will be appreciated, and as will be explained shortly, the replaceable DAA258can house components different than those necessary to connect to a telephone line such as providing the components necessary to interface with a computer network or provide wireless communication service such as cellular telephone service or carry out some other function.

Represented inFIG. 14are grooves255into which are received respective ridges262provided on the sides of the replaceable DAA258. The grooves255are more clearly represented in the end view ofFIG. 14A. The grooves255and the ridges262function to guide the replaceable DAA258into and out of the cavity254. The replaceable DAA258is preferably held in the cavity254by a pair of flexible ledges264which engage corresponding notches257provided on the inner surface of the cavity254.FIG. 14Billustrates the communications card250when the replaceable DAA258is fully inserted into the cavity254.

To remove the replaceable DAA258from the remainder of the communications card250, a pair of tabs266are squeezed, resulting in the ledges264being released from the notches257, and allowing the replaceable DAA258to be extracted from the cavity254. It will be appreciated that many different arrangements can be arrived at by those skilled in the art to allow the components of the replaceable DAA258to be connected to, and removed from, the remainder of the communications card250.

The replaceable DAA258illustrated inFIG. 14is provided with a receptacle module270which is provided with a pair of RJ-xx series receptacles represented at278A&B which are adapted to connect to a communications line having a RJ-xx series plug such as those represented inFIGS. 1–3. It will be appreciated that the RJ-xx series receptacles278A&B can be provided with the expandable member114shown inFIG. 2if desired. It is within the scope of the present invention to provide the receptacle module270with structures to allow its removal as shown inFIG. 1or to include structures to allow extension out of, as shown by the phantom image ofFIG. 14, the replaceable DAA258and retraction into the replaceable DAA258in the direction of arrow272as represented inFIG. 14B.

FIGS. 14C–Eare high level block diagrams illustrating some of the preferred functions carried out by the replaceable DAA258. As suggested above, a number of different replaceable DAA258units can be provided, each being adapted to carry out a particular function and the user changing the replaceable DAA258as necessary. Provided below in Tables A–C are descriptions of the preferred functions carried out by the blocks represented inFIGS. 14C–E, respectively.

FIG. 14Fshows a receptacle module270A which includes only a single RJ-xx series receptacle. Some country's regulations require that only a single telephone line be connected to a telecommunications device. The RJ-xx series receptacle illustrated inFIG. 14Fis preferably an eight conductor RJ-45 receptacle. The DAA to which the receptacle module270A is connected preferably provides the interfacing functions needed to directly attach to the telephone system of the particular country or countries.

Reference will next be made toFIGS. 15A–Dwhich are detailed views of the receptacle module270and the structures which allow the receptacle module270to extend out of or retract into the replaceable DAA258(shown inFIG. 14). It will be appreciated that the structures which allow extension and retraction of the receptacle module270can be incorporated into the replaceable DAA258, directly into a communications card250, or into any other device which would benefit from the compact communications connector described herein.

Prior to the present invention, if the structures providing RJ-xx series connectors were affixed to the PCMCIA pOcommunications card, the connectors would be broken off or damaged and the user would be required to discard the entire communications card and would be stranded with an inoperative communications card. The devices described in U.S. Pat. No. 5,183,404 to Aldous are particularly afflicted by this problem. Prior to the advent of the instant invention, the industry had not recognized the described incidents as a significant problem and the industry has not been able to arrive at the solution described herein.

The present invention allows the structures which provide the communications receptacles to be readily replaced by the user. The user may need to replace the structures which provide the communications receptacles due to damage or in order to interface with different communications lines or devices. The present invention provides these advantages which have not otherwise been available in the industry. Thus, the user can replace damaged receptacle structures, or replace the structure if other functions are necessary, quickly and without any difficulty.

Represented inFIGS. 15A and 15Bis a receptacle module270which includes two RJ-xx series receptacles, generally represented at278A&B.FIG. 15Ashows the receptacle module270in its retracted position.FIG. 15Bshows the receptacle module270in its extended position. Each of the RJ-xx series receptacles278A&B is provided with four conductors represented at bracket284. It will be understood that the representation of the RJ-xx series receptacles0ödescribed herein is exemplary of one presently preferred application with inclusion of other types of connectors and devices also being within the scope of the present invention.

A frame280is shown inFIGS. 15A&B. The frame280is, for example, received into a cavity (not represented inFIGS. 15A&B) provided in the replaceable DAA258and is held in place by locking ridges290which engage notches273(FIG. 14). An electrical connector represented at282inFIGS. 15A–Bprovides electrical connection and provides further physical stability and can be selected by those skilled in the art using the information provided herein. The frame280is removed from the replaceable DAA258by the user squeezing together tabs292and the frame280being pulled from the replaceable DAA258. It will be appreciated that the structures represented inFIGS. 15A&Bcan be incorporated into many different devices which are now available in the industry or which may become available in the future.

As represented inFIGS. 15A&B, the receptacle module270is biased in its extended position by springs286. The springs286are held in place by posts286A and286B. A flexible interconnecting circuit288provides electrical connection between the connector282and the conductors284. Further information regarding the interconnecting circuit288will be provided in connection withFIGS. 15C&D. As will be appreciated by those skilled in the art, the structures described herein provide the advantage of being more compact than previously possible following conventional teachings in the art.

FIGS. 15C&Dshow a flexible interconnecting circuit288which provides a plurality of conductors indicated at288A. The flexible interconnecting circuit288, rather than utilizing pin and socket terminal connections, relies on surface mount connections thus making the structures more compact. The electrical signals received at the connector282(FIGS. 15A&B) are conveyed to conductors (not illustrated) formed on the surface of a bar289and a holding clip291presses the conductors288A onto the appropriate conductors formed on the surface of the bar289. The flexible interconnecting circuit288bends as necessary to accommodate the extension and retraction of the receptacle module270.

To make a surface electrical connection with the conductors of the RJ-xx series receptacles, the conductors284p0being held in place by a member271, the flexible interconnecting circuit288is folded so that the conductors288A are pressed against a corresponding conductor represented at284. The flexible interconnecting circuit288is held in place on the member271by a clip277. The receptacle module270can provide electrical interconnection between the conductors284of the RJ-xx series receptacles278A&B. Using the described structure, a reliable and compact arrangement is provided to make electrical connection with the RJ-xx series receptacles.

Referring again toFIGS. 15A&B, a pair of flexible arms279are each provided with a protruding knob281which is received into a groove formed in the inner surface of the frame which allows the receptacle module270to slide within the frame280and hold the receptacle module270in either its extended or retracted position. Projecting from the side of the receptacle module270are wings282which provide further positional stability. The leading edge282A of the wings282abuts a stop283on the frame to limit the extension motion of the receptacle module270. The operation of the flexible arms279in the retraction and extension movement will be explained in further detail by reference toFIGS. 16A–D.

FIG. 16Ais a side view of the inner surface of the frame280showing a groove306formed therein and the receptacle module270in its retracted position. As can be seen inFIG. 16A, the knob281is held in a trough306A. The shape of the knob281and the shape of the trough306A, together with the biasing action of the springs (286inFIGS. 15A&B), keep the knob281in the trough306A. When extension of the receptacle module (270inFIGS. 15A&B) is desired, the user pushes in on the receptacle module270so that the sloping rear side of the knob281causes the free end of the flexible arm279to bend upward allowing the knob281to escape the trough306A and move forward in the groove306to the extended position represented inFIG. 16B.FIG. 16Cprovides a side view of the flexible arm279showing its vertical movement as represented by arrow308.FIG. 16Dprovides a top view of a portion of the receptacle module270further showing the shape of the knob281and the horizontal movement of the flexible arm279. It will be appreciated that the described structures provide a simple and reliable arrangement for extending and retracting the receptacle module270and which advantageously is more compact than previously available structures. By making the retraction and extension structures more compact, more room is provided for other components.

Reference will next be made toFIGS. 17A–Cwhich illustrate in detail additional structures which allow the receptacle module270to extend out of or retract into the replaceable DAA258(shown inFIG. 14) and the electrical interconnection between the connector287and the conductors284in the RJ-xx series receptacles. Many of the structures represented inFIGS. 17A&Bare the same as the correspondingly numbered structures represented inFIGS. 15A&B. Thus, only the differences between the represented structures will be described.

Represented inFIGS. 17A&Bis one of at least two exposed conductors represented at294A which is attached to the inner surface of frame280.FIG. 17Cshows two sliding electrical contacts296A and296B. The sliding electrical contacts296A&B are preferably of the spring type to ensure that each of the sliding electrical contacts296A&B makes solid electrical contact to each of the respective conductors, one of which is represented at294A in the top views ofFIGS. 17A&B. An electrical connection is made from the sliding electrical contacts296A&B, through the receptacle module270, and to the appropriate conductor284. It will be understood that many variations on the electrical interconnection structures can be carried out within the scope of the present invention using the information set forth herein.

FIGS. 18A&Bwill be referred to next to describe the structures which allow the receptacle module270to extend and retract.FIG. 18Ais a cross sectional top view of the receptacle module270showing a groove formed therein. Still referring toFIG. 18A, provided on the inner surface of the stop283is a pin301which is held in a recess304and biased outwardly from the recess304by a spring302. InFIG. 18A, the solid image of the stop283and the pin301shows their position in the groove300when the receptacle module270is in its extended position. The biasing force of the spring286, partially represented inFIGS. 18A&B, holds the receptacle module270in its extended position.

Reference will now be made to bothFIGS. 18A and 18Bto explain the movement of the receptacle module270from its extended position to its retracted position. When the receptacle module270is to be moved to its retracted position, the user (not represented in the figures), pushes the receptacle module270toward the frame280. The pin301travels in the groove300up the ramp300A and into the well300B where the pin301is held. The retracted position of the receptacle module270is represented by the phantom image inFIG. 18A. To move the receptacle module270from its retracted position to its extended position, the user again pushes the receptacle module270inward toward the frame280which causes the pin301to move out of the well300B up a ramp indicated by arrow300C. The user then releases the receptacle module270which allows the receptacle module270to extend and the pin301to travel down a ramp indicated by arrow300D where the pin301again enters groove300and the receptacle module270completes its extension.

Reference will next be made toFIGS. 19A–C. In order to accommodate wireless communication between the communications card and a wireless communication system, an antenna is provided on the communications cards represented inFIGS. 19A–C. The embodiments of the present invention illustrated inFIGS. 19A–Care particularly adapted for accommodating cellular telephone signals but those skilled in the art can readily adapt the embodiments to accommodate other communication systems, including those utilizing radio frequency techniques as well as other mediums.

FIG. 19Aillustrates an antenna312which pivots into and out of the end of the communications card250in the directions of arrow312A. When use of the antenna is desired, the user depresses a release button315which allows the antenna to pivot out of the end of the communications card.

FIG. 19Billustrates an antenna318which is pivotally mounted on a retractable block314. When use of the antenna is desired, the user depresses a release button315which allows the antenna318to pivot in the directions of arrow318A. The retractable block314can be stored within the communications card and extended and retracted in the directions of arrow314A and released from its retracted position by depressing button316.

FIG. 19Cillustrates an antenna322which is pivotally mounted on a retractable block320. The retractable block320is extended by depression of button316. When the retractable block320is extended, the antenna322is pivoted up or down in the direction of arrow322A. Also provided on the retractable block320is a receptacle324allowing a communications line to also be attached thereto.

Each of the arrangements represented inFIGS. 19A–Ccan be best adapted for use with particular types of antenna which may assume shapes and sizes very different than the illustrated antennas. For example, antennas which are vertically polarized, horizontally polarized, or circularly polarized can have application with the embodiments of the present invention. Moreover, the antennas used with the embodiments illustrated inFIGS. 19A–Ccan include components which extend or further pivot to increase the length of, or change the shape of, the antenna. Those skilled in the art will appreciate that the components necessary to carry out wireless communication, such as cellular telephone communication, can be packaged in the communications card250or in a DAA adapted for such purpose. Further information regarding wireless computer networks can be obtained from IEEE 802.11 Standard (and any available drafts thereof) which is now incorporated herein by reference in its entirety.

Reference will next be made toFIG. 20which shows a communication card250and a replaceable DAA332which are adapted to interface with a portable cellular telephone via a cable334and a connector336which attaches directly to a corresponding connector (not illustrated) on the portable cellular telephone (not illustrated). It will be appreciated that those skilled in the art will be able to provide replaceable DAAs332and connectors336which are adapted to function with any number of cellular telephones or other communications devices and which allow the user to easily and quickly change the application to which the communications card is put.

Reference will next be made toFIG. 21.FIG. 21provides a perspective view of a communications card generally designated340. The communications card340follows the PCMCIA (also referred to as PC Card) Type III standard for dimensions and configuration. The height of a PCMCIA Type III card is still not great enough to allow a standard RJ-xx series receptacle to be mounted therein. In the communications card340illustrated inFIG. 21, a T-shaped cutout328is removed from the housing of the communications card340. The T-shaped cutout328accommodates the biased clip12and the ridge18present on the plug10. The shape of the T-shaped cutout328engages the biased clip12and the ridge18to hold the plug10in place. Represented inFIG. 21are two receptacles, each generally designated at326. Preferably, one of the receptacles326is an eight conductor RJ-45 receptacle, which is called for in some computer network standards, and the other of the receptacles326is an RJ-11 receptacle. As can be seen in the figures, and particularly inFIG. 21, the PCMCIA Type III PC card340includes an upper surface350and a lower surface352which form a portion of the housing for the communication card340. Also represented inFIG. 21is a connector338which can be used to make a connection to another communication device (in a manner similar to that described in connection with connector336illustrated inFIG. 20), as is known in the art.

Reference will next be made toFIG. 21Awhich shows all of the structures represented inFIG. 21with the inclusion of a cover342which shields the T-shaped cutouts328and the receptacles326. The cover342is preferably a thin membrane-like material which is attached to, or integral with, the upper surface. The cover can preferably be fabricated from a material having a thickness in the range from about 0.001 inch to about 0.050 inches thick such that the card340maintains compliance, or substantial compliance, with the pertinent PCMCIA card physical thickness standard. It is also within the scope of the present invention to fabricate the cover342from an elastic material. Moreover, the cover342can be structured to straddle the entire upper surface350of the PC Card340, or just a portion of the upper surface350, as deemed best for the particular application of the invention.

Reference will next be made toFIG. 22.FIG. 22is a perspective view of another communications card, generally indicated by the bracket351, in accordance with the present invention. The communications card351preferably follows the PCMCIA (also referred to as PC Card) Type III standard for dimensions and configuration. The communications card351has a plurality of RJ-xx series receptacles358A–C which are each provided with a pivoting cover, one of which is indicated at362. The pivoting cover362pivots about pin364as represented inFIG. 22and is biased closed by biasing means369.

The communications card351include two major components, a card body351B and a connector housing351A. Many of the embodiments of the present invention described hereinafter will have a similar structure and the description provided now will apply to all similarly structured embodiments. The card body351B includes a front end370which provides connector sockets in accordance with the PCMCIA standard. The connector housing351A provides the necessary physical/electrical components to connect to one or more communications lines. For example, the connector housing351A includes RJ-xx series receptacles358A–C and an auxiliary connector, generally indicated at359, which preferably can be a connector suitable for coupling to a wireless communication device, for example a portable telecommunications device which complies with the GSM (Global System for Mobile Communications) communications standard. The connector housing351A so preferably includes the DAA components such as those described earlier and others which perform similar functions.

The connector housing351A can be removed from the card body351B and replaced with another connector housing351A in case a connector housing351A becomes damaged, if another DAA is needed by a user, and/or if different connectors are needed. It is also to be appreciated that the card body351B and connector housing351A arrangement illustrated inFIG. 22provide advantages even if the distribution of components is different than that preferably described herein, for example, if the DAA is located in the card body351B rather than in the connector housing351A.

Still referring toFIG. 22, to provide a secure mating between the card body351B and the connector housing351A, a female portion353B receives a male portion353A when the connector housing351A is mated to the card body351B. Moreover, the structure of the electrical connector which provides for communications between the card body351B and the connector housing351A, comprising a connector receptacle354B and a connector plug354A, further enhances the physical and electrical connection between the card body351B and the connector housing351A. Two spring fingers356B are received by recesses, one of which is represented at356A, to further secure the card body361B and the connector housing351A together. It is to be appreciated that the structures illustrated inFIG. 22, and the other figures herein described, are merely exemplary and many different connector configurations can be used within the scope of the present invention.

When the connector housing351A and the card body351B are joined together, and the communications card351is received into a computing device, communications via a communications line, such as that shown connected to the RJ plug10, is read to occur. A pivoting cover, such as that represented at362, is provided for each one of the RJ-xx series receptacles358A–C. The RJ-xx series receptacles358A–C can be fabricated to receive any of the RJ-xx series plugs, such as RJ-11, RJ-12, and RJ-45 plugs. With the pivoting covers in the closed position, the components of the connector housing351A are protected and the overall length of the communications card351is reduced. When the pivoting cover, for example pivoting cover362, is moved in the direction of arrow360, the RJ plug10can be inserted into the recess formed by the pivoting cover362. A ledge366engages the biased clip12and holds a plurality of spring conductors368located in the recess in electrical contact with the corresponding contacts in the RJ plug10when inserted therein.

Those skilled in the art will readily be able to arrive at numerous alternative structures capable of providing the electrical functions required by the connector housing351A and the card body351B using the information set forth herein and known in the industry. Thus, when the pivoting cover362is open as illustrated inFIG. 22, an RJ plug is inserted therein and communications via a communications line can efficiently occur.

Reference will next be made toFIG. 23.FIG. 23is a perspective view of another communications card, generally indicated by bracket374. The communications card374includes many of the structures described in connection with communications card351illustrated inFIG. 22. Thus, only the different and/or additional structures will be discussed in connection with the communications card374represented inFIG. 23.

As shown inFIG. 23, a card body374B and a connector housing374A are included in the communications card374. The connector housing374A includes three RJ-xx series receptacles Which are contained in sliding drawers, generally indicated at376A–C. The sliding drawers376A–C each include a drawer front, one of which is shown at378, and drawer sides, represented at380. Drawer ridges, one of which is shown at380A, are provided on the drawer sides380and are one example of a structure which can be used to allow the sliding drawers to retract into, and extend from, the connector housing374A. When the sliding drawers376A–C are in their closed position, the internal components of the connector housing374A are shielded from damages and contamination.

As represented inFIG. 23at sliding drawer376A, when an RJ plug10is to be connected, the sliding drawer378is extended from the connector housing374A, and the RJ plug10is inserted therein at an angular orientation as represented inFIG. 23. The sliding drawers376A–C include structures to hold the RJ plug10at the preferred angular orientation when the RJ plug10is inserted therein. As the RJ plug10is received into the sliding drawer376A the biased clip12engages a ledge384which holds the electrical contacts of the RJ plug10in continuity with a plurality of conductors, indicated at382in the sliding drawer376A. Those skilled in the art will readily be able to arrive at numerous different structures which provide the electrical functions to be carried out by the connector housing374A and the card body374B using the information set forth herein and known in the industry. When the communications card374is not being used, all of the sliding drawers376A–C are closed and components of the connector housing374A are protected from damage and the overall length of the communications card374is preferably and substantially within the PCMCIA Type III standard. Desirably, as is the case with the other embodiments described herein, the components which carry electrical current from the communications line are shielded from contact with structures in the surrounding environment thus preventing the contacts from being inadvertently shorted together or shorted to ground or conveying current to a human being.

FIG. 24Awill be referred to next to describe another communications card within the scope of the present invention, generally indicated at390.FIG. 24Ais a perspective view of the communications card390which includes a plurality of RJ-xx series receptacles positioned in sliding drawers, the sliding drawers being generally indicated at394A–C, with each of the sliding drawers394A–C being provided with a movable bottom400which functions to shield electrical conductors398from contact with the surrounding environment. A card body392preferably includes the components necessary to provide the communications functions which are desired by the user and which can be arrived at by those skilled in the art using the information set forth herein and using the information readily available in the industry.

As shown best inFIG. 24B, which is a cross sectional view taken along line24B—24B ofFIG. 24A, the structure of the sliding drawers394A–C each include a movable bottom400.FIG. 24Bshows the movement in the direction of arrow402of the movable bottom400to shield the electrical conductors398when there is no RJ plug present and the position of the movable bottom400when an RJ plug is received into the recess, two of which are indicated at396A&B inFIG. 24A, when an RJ plug is received therein.

As will be appreciated from an examination ofFIG. 24A, the recesses396A&B include structures, such as ledges393A&B, to engage the biased clip of the RJ plug. Also as shown inFIG. 24A, the moveable bottom400preferably includes a bevel404to urge the movable bottom400in an upward position when the sliding drawers394A–C are moved into their retracted position.

The communications card420includes a plurality of RJ-xx receptacles, generally indicated at422A–C, each formed by a pair of retractable and expanding jaws, two of which are represented at424A&B. When in the retracted position, as shown with RJ-xx receptacles422B&C, the communications card po420(including card body420B and connector housing420A) substantially complies with the dimension requirements of the PCMCIA Type III standard. Included in the connector housing420A are the structures which allow the jaws424A&B to be extended out of and retracted into the connector housing351A in the directions of arrow432and also to pivot in the directions of arrows430as well as to bias the jaws424A&B toward each other.

An RJ plug10represented inFIG. 25is received into the receptacle422A formed by the jaws424A&B by manually separating the jaws424A&B and inserting the RJ plug10between the jaws424A&B. The jaws424A&B are biased toward each other thus capturing the RJ plug10therein and holding the electrical contacts of the RJ plug10in continuity with the conductors, one of which is represented at428, in the jaw424A. A ledge426engages the biased clip on the RJ plug10to further secure the RJ plug10in position in the jaws424A&B. The structures represented inFIG. 25provide that the RJ plug10and the communications card420can be easily connected and disconnected and that the internal components of the communications card420, including the conductors428, are shielded from the surrounding environment.

FIG. 26Ais a partial perspective view of a communications card generally indicated at440which includes two different connectors, an RJ-xx series receptacle generally indicated at442and an auxiliary connector, generally indicated at448, which preferably can be a connector suitable for coupling to a wireless communications device, for example a portable telecommunications device which complies with the GSM communications standard, both of which are positioned on a retractable/extendable member444. The retractable/extendable member444is shown in an extended position inFIG. 26Aand is shown in a retracted position inFIG. 26B. Those skilled in the art can readily arrive at the structures included in the communications card440needed to implement the extension and retraction functions of the member444. The electrical connections included in the communications card440can be readily arrived at using the information set forth herein and using the information well-¼known in the industry.

FIGS. 32A&Bare perspective views of a PC card610which operatively receives a magnetic disk storage medium614in a slot614. When inserted into a PC card slot on a computing device so that a front end618engages a PC card socket, the internal components, represented at616, of the PC card610provide for data transfer between the PC card610(and thus the computing device) and the magnetic disk storage medium614. It will be appreciated that the optical storage medium can be used in the place of the magnetic disk storage medium.

One example of the magnetic disk storage medium614is the disks used in the clik!™ drive which has been announced by Iomega. Current specifications designate that clik!™ disks (cartridges) will be about 2.16 inches by about 1.98 inches by about 0.077 inches and which hold 40 MB of data and which are suited for applications which currently require flash memory cards. The clik!™ disks and drive are particularly suited for inclusion in miniature apparatus such as Personal Digital Assistants (PDAs) and other miniature digital electronic devices. Further information regarding the clik!™ disk can be p0obtained from the URL http://www.iomega.com/product/clik and the information contained at the URL and the information contained in all links available at such URL as well as the information contained in all links available at such URL as of the filing date of this application is now incorporated by reference herein in their entireties.

Reference will next be made toFIG. 33which is a perspective view of a PC card, generally indicated at630, which includes a first slot, generally indicated at632A, and a second slot, generally indicated at632B, each which operatively receive a memory cards,636A and636B, respectively. The slots632A and632B are each provided with a set of connector pins634A and634B which are arranged in accordance with a memory card standard. Internal to the PC card630are the components needed to interface both memory cards636A&B to a computing device into which the PC card630is inserted. The PC Card630preferably adheres to the PCMCIA Type III standard and desirably allows two memory cards to be simultaneously interfaced with a computing device. Using the information contained herein, those skilled in the industry will readily arrive at the hardware and software necessary to convey data between a computing device in which the PC Card630is inserted and one or both memory cards636A&B.

Reference will next be made toFIGS. 34A&Bwhich are a perspective view and a detailed perspective view, respectively, of a communications card generally indicated at650. The communications card350can simultaneously receive up to three RJ plugs, such as the RJ plug10represented inFIG. 34B. As shown best inFIG. 34A, a cover652is provided with a finger pull652A and the cover652pivots about an axis654in the directions of arrow660and as shown by the phantom image. When the cover652is moved to its open position represented inFIG. 34B, three sets of conductors664are exposed. The sets of conductors664are arranged to correspond to the contacts provided in the RJ plug10. With the cover652in the position represented inFIG. 34B, a plurality of plug bails656A–C are lowered to the position shown inFIG. 34B. The bails656A–C are biased in an upward direction by spring662. When an RJ plug10is inserted into one of the bails656A–C, the biased clip12engages a ledge658A–C so that the RJ plug10is operatively held in place and signals can be passed between the RJ plug and the communication card650. The communication card650allows more than one RJ plug to be simultaneously and conveniently connected to a computing device.

Reference will next be made toFIG. 35which is a perspective view of a communications card, generally indicated at680, in accordance with the present invention. The communications card680includes a retractable receiver member692which provides two RJ-xx series receivers, generally indicated at684A&B. Each of the receivers684A&B are provided with pivoting bails686A&B which pivot in the directions of arrow688. The pivoting bails686A&B, when in the position represented inFIG. 35, engage the biased clip and the body of the RJ plug and hold the RJ plug in an operative position so that the conductors, one set of which is represented at686A, engage the corresponding contacts provided on the RJ plug. The receiver member692retracts into, and extends from, the communications card680in the directions of arrow682. The components housed within the communications card680which allow electrical continuity to be maintained with the conductors686A as the receiver member is retracted and extended are represented at box690.

In view of the foregoing, it will be appreciated that the present invention provides many different communications line receptacles for use with a miniaturized communications device wherein the electrical contacts are shielded from the surrounding environment and which is resistant to breakage and which can be moved out of the way when not being used. The present invention also provides communications line receptacles which are easily replaceable if broken. The present invention also provides communications cards which can be readily adapted to meet various communications standards and which can provide wireless communications.
