FIGS. 4A-4D illustrate cross section, side, top, and angled views of an exemplary male plug connector 400 (e.g., male plug connector 302 of FIG. 3) according to one embodiment of the present invention. Referring to FIG. 4A, a cross section view of male plug connector 400 is illustrated. As shown in FIG. 4A, male plug connector 400 can include an plug body 402, a plug housing 404, hooks 406, and access pathways 408. Plug body 402 can be any suitable housing that allows a user to hold or grip male plug connector 400 such that the mating or interfacing of the male plug connector to a female receptacle connector of a portable electronic device can be facilitated. Plug body 402 can be composed of any suitable material or combinations of material, such as plastic, metal, wood, acrylic, glass, composite material, and/or the like. In some embodiments, plug body 402 can include an image, icon, label, or other element for identifying the male plug connector.

In some embodiments, plug body 402 can at least partially enclose plug housing 404 and hooks 406. Plug body 402 can further include access pathways 408 that enable an external unlocking tool to access hooks 406. As will be discussed below, access pathways 408 can be passages within plug body 402 that lead to hooks 406.
Plug housing 404 can be any suitable connection mechanism for connecting with the female receptacle connector of a portable electronic device. Plug housing 404 can be composed of any suitable material or combinations of material, such as plastic, metal, wood, acrylic, glass, composite material, and/or the like. In some embodiments, plug housing 404 can be formed to fit the receptacle tongue of a female receptacle connector. For example, plug housing 404 can include an insert opening formed to accept a receptacle tongue. In certain embodiments, plug housing 404 can include one or more contacts or pins. When plug housing 404 is mated with a receptacle tongue, the plug housing's pins can be electrically coupled to the pins of the receptacle tongue. In doing so, various functionalities can be facilitated. Illustratively, power can be supplied to a portable electronic device. A security signal can additionally be transmitted from the portable electronic device to a connected security system.
In some embodiments, each pin can be located at a pin location within plug housing 404. The number of pins in plug housing 404 can be equal to or less than the total number of pin locations in the plug housing. Illustratively, plug housing 404 can include 30 pin locations with 30 pins assigned to each location. As another example, plug housing 404 can include 30 pin locations, but have only 6 pins. The pins within plug housing 404 can be assigned to any suitable pin location. The assigned locations of the pins can be, but need not be consecutive.
In some embodiments, plug housing 404 can include openings disposed on each of its sides. The openings can be configured to allow portions of hooks 406 (e.g., locking portions 410) to exit through the opening.
Hooks 406 can be any suitable mechanism for engaging male plug connector 400 with the female receptacle connector of a portable electronic device. Hooks 406 can be formed of a flexible metal or other material having a spring-like quality; can be biased by a spring; etc. such that the hooks can be deflected during the connection of male plug connector 400 to a female receptacle connector, and returned to their original positions following the connection of the male plug connector to the female receptacle connector. Illustratively, as male plug connector 400 is being mated with a female receptacle connector, hooks 406 can be shifted inward. Following the mating event, hooks 406 can be shifted back to their original positions. In shifting back to their original positions, hooks 406 can engage with the female receptacle connector as to lock the male plug connector to the female receptacle connector.
For example, according to some embodiments, hooks 406 can be configured to tilt inward during a mating event. In particular, each hook 406 can have its base fixed or attached within plug body 402 and/or plug housing 404. Each hook 406 can be further configured to pivot around its base such that the hook can be tilted inward during a mating event. As a result of the tilting, each hook's 406 locking portion 410 (described in greater detail below) can retreat into plug housing 404. Following mating, each hook 406 can tilt back to its original position such that its locking portion 410 extends back outside of plug housing 404, thereby locking the male plug connector with a female receptacle connector.
As another example, according to certain embodiments, hooks 406 can be configured to bend inward during a mating event. In particular, each hook 406 can have its base fixed or attached within plug body 402 and/or plug housing 404. Illustratively, the base of each hook 406 can be anchored by, for instance, a channel within plug body 402. The upper portion of each hook 406 can be configured to bend inward during a mating event. As a result of the bending, each hook's 406 locking portion 410 can retreat into plug housing 404. Following mating, the upper portion of each hook 406 can bend back to its original position such that each hook's 406 locking portion 410 extends back outside of plug housing 404, thereby locking the male plug connector with a female receptacle connector.
As still another example, according to some embodiments, hooks 406 can be configured to move inward during a mating event. In such embodiments, the base of each hook is not fixed to a particular position within plug body 402 and/or plug housing 404. Rather, during a mating event, the entirety of each hook can be moved inward. As a result of the movement, each hook's 406 locking portion 410 can retreat into plug housing 404. Following mating, each hook 406 can be moved back to its original position such that its locking portion 410 extends back outside of plug housing 404, thereby locking the male plug connector with a female receptacle connector. In such embodiments, hooks 406 can remain vertical (or substantially vertical) and remain unbent during mating.
As shown in FIG. 4A and briefly discussed, hooks 406 can include locking portions 410 that enable each hook 406 to engage a female receptacle connector. Each locking portion 410 or “barb” can protrude through an opening on a side of plug housing 404. As discussed, an individual hook 406 can be moved, tilted, or bent during a mating event such that its associated locking portion 410 can retreat within the opening. Each locking portion 410 can be structured and shaped in a suitable manner in order to engage with a female receptacle connector. For example, an individual locking portion can have a triangular shape. The shape can approximate, for instance, a right-angled triangle. In some embodiments, side 414 of an individual locking portion 410 can be sloped relative to a female receptacle connector such that an individual hook 406 can be engaged or locked to the female receptacle connector with a relatively small amount of force. In particular, a relatively small amount of force can be required to cause individual hook 406 to enter an inner cavity of the female receptacle connector. Side 412 of the individual locking portion 410 can be parallel or substantially parallel to the inner cavity of the connected female receptacle connector. As a result, side 412 can act as a retention mechanism that locks male plug connector 400 to the female receptacle connector. In some embodiments, the force required to disconnect male plug connector 400 from the female receptacle connector can be larger than the force needed to connect the male plug connector to the female receptacle connector. In certain embodiments, the force required to disconnect male plug connector 400 from female receptacle connector can be sufficiently large as to break hooks 406 when the hooks are engaged to the female receptacle connector.
As discussed, side 412 can be parallel or substantially parallel to the base of an inner cavity of a female receptacle connector. In certain embodiments, side 412 can be ±5 degrees to the base of an inner cavity of a female receptacle connector. In other embodiments, side 412 can be ±15 degrees to the base of an inner cavity of a female receptacle connector. In some embodiments, side 412 can be a length between 1.05 and 1.30 mm. For example, side 412 can be 1.13 mm in length.
Access pathways 408 can include access paths configured to receive at least a portion of an external unlocking tool. For example, male plug connector 400 can include two access pathways. As shown in FIG. 4A, the two access pathways can be situated on opposite sides of the male plug connector. In some embodiments, the access paths of access pathways 408 can enable the unlocking tool to access hooks 406 and cause the hooks to disengage from a female receptacle connector. More specifically, pins of an external unlocking tool can travel along the length of the access paths and contact release points of hooks 406 such that the hooks are moved, tilted, or bent inward. In doing so, the hooks 406 can become disengaged from the female receptacle connector such that a portable electronic device can be easily disconnected from the female receptacle connector. Access pathways 408 can be any suitable shape and include any suitable dimensions for receiving an external unlocking tool. For example, each access pathway 408 can be cylindrical in shape. Each access pathway 408 can additionally include a diameter such that a special tool is required to access the pathway.

FIGS. 7A-7C illustrate the engagement of a male plug connector (e.g., male plug connector 400) to a female receptacle connector (e.g., female plug connector 600) according to one embodiment of the present invention.
FIG. 7A illustrates a cross section view of male plug connector 400 and female receptacle connector 600 prior to their connection. FIG. 7B illustrates a cross section view of male plug connector 400 and female receptacle connector 600 as the connectors are being connected. As shown in FIG. 7B, each hook of male plug connector 400 can be tilted inward by the walls of female receptacle connector 600. Each hook, however, can maintain an outward force such that each hook moves along and touches the surface of a wall of female receptacle connector 600. FIG. 7C illustrates a cross section view of male plug connector 400 and female receptacle connector 600 after the connectors have been fully connected. As shown in FIG. 7C, due to the outward force of the hooks of male plug connector 400, the hooks can be tilted back to their original positions. As a result, the locking portions of the hooks can enter the inner cavities of female receptacle 600. In doing so, male plug connector 400 can be sufficiently locked in place with female receptacle connector 600.
FIGS. 8A-8E illustrate various views of an exemplary unlocking tool 800 (e.g., unlocking tool 208) according to one embodiment of the present invention. FIG. 8A illustrates a cross section view of unlocking tool 800. Unlocking tool 800 can be any device suitable for disengaging a male plug connector from the female receptacle connector of a portable electronic device. As shown in FIG. 8A, unlocking tool 800 can include user initiation portions 802 and a housing 804.
User initiation portions 802 can be a set of (e.g., two) wire form modules that can be used to disengage the hooks of a male plug connector from a female receptacle connector. User initiation portions 802 can be implemented using any suitable material or combination of materials, such as plastic, metal, wood, acrylic, glass, composite material, and/or the like. For example, user initiation portions 802 can be implemented using a suitable metal or composite material with sufficient flexibility such that the initiation portions can be bent in response to the application of a slight force by, for instance, the hand of a user. Following the application of force, the user initiation portions 802 can return to their original positions.
In some embodiments, each user initiation portions 802 can include a pin 812. As shown in FIG. 8A, pin 812 can be situated at an end of an individual user initiation portion 802. Each pin 812 can be a segment of an individual user initiation portion 802 that has a reduced or a smaller diameter relative to other parts of the user initiation portion. According to some embodiments, pins 812 can each include a diameter of 0.8 mm or less. In some embodiments, an individual pin 812 can, in response to user application of unlocking tool 800, access a pathway of a male plug connector and cause a hook of the male plug connector to disengage from a female receptacle connector. Illustratively, a user can apply pressure to portions of user initiation portions 802 (e.g., the portions extending out of cavity 806, which is described below). Such pressure can cause pins 812 to be moved into the access pathways of a male plug connector, and contact the male plug connector's hooks. The force of the contact can cause the hooks to be moved, titled, or bent inward such that the hooks can be disengaged from a female receptacle connector. Upon disengagement of the hooks, a user can freely remove the male plug connector from the female receptacle connector. In some embodiments, pins 812 can be of sufficient lengths to enable the pins to pass through the pathways of a male plug connector and disengage the hooks of the male plug connector.
In certain embodiments, a portion of each user initiation portion 802 can extend horizontally (e.g., portions 816) within a cavity (e.g., cavity 806, which is described below) of housing 804. In doing so, the portions can together act to restrict or stop the movement of a male plug connector into the lower portion of the cavity. In doing so, the male plug connector can be vertically aligned with unlocking tool 800. For example, portions 816 can vertically align pins 812 of the user initiation portions with the access pathways of the male plug connector.
Housing 804 can be implemented using any suitable material or combination of materials, such as plastic, metal, wood, acrylic, glass, composite material, and/or the like. In some embodiments, for example, housing 804 can be an injection molded plastic housing. According to certain embodiments, housing 804 can be a non-descript color, such as black, white, or various shades of gray. In some embodiments, housing 804 can be generally rectangular. More specifically, the outer and inner surfaces can be substantially rectangular or include mostly straight surfaces. In some embodiments, housing 804 can include surfaces that are slightly curved or rounded.
As shown in FIG. 8A, housing 804 can form a cavity 806. Cavity 806 can include dimensions that enable the cavity to receive a male plug connector. In certain embodiments, a male plug connector can be received into cavity 806 through a top opening of housing 804. In some embodiments, the male plug connector can be positioned within cavity 806 such that the access pathways of the male plug connector can be horizontally aligned with pins 812. By horizontally aligning pins 812 with the pathways, embodiments can enable the pins to be used to disengage a male plug connector from a female receptacle connector.
In some embodiments, housing 804 can include bottom openings 810. According to certain embodiments, bottom openings 810 can be used to receive, for example, a lanyard, a chain, or some other mechanism for enabling a user to carry unlocking tool 800 on his or her person. For example, one end of a lanyard can be threaded into a first opening of the bottom openings. The same end can further be threaded out a second opening of the bottom openings. In doing so, the lanyard can be sufficiently attached to housing 804 such that unlocking tool 800 can be carried by a user. Illustratively, a user can wear, around his or her neck, the lanyard in order to conveniently carry unlocking tool 800.
In some embodiments, housing 804 can include pin openings 814 for receiving pins 812 of user initiation portions 802. The pin openings can have dimensions such that only pins 812 of user initiation portions 802 can pass through the openings. In particular, once the pins 812 have passed entirely through the openings, walls surrounding openings 814 can restrict or stop the inward movement of user initiation portions 802. In doing so, housing 804 can enable user initiation portions 802 to be moved sufficiently inward as to disengage the hooks of a male plug connector while preventing the user initiation portion from being moved so far as to cause damage to the hooks or otherwise interfere with the operations of the male plug connector.
In some embodiments, housing 804 can include a set of channels 808, which can receive user initiation portions 802. In some embodiments, the channels can be filled with an adhesive material, such as glue or epoxy. In doing so, user initiation portions 802 can be mated to housing 804.
FIG. 8B illustrates a bottom view of unlocking tool 800. In particular, FIG. 8B shows bottom openings 810, which can be used with a lanyard to enable unlocking tool 800 to be conveniently carried. FIG. 8C illustrates an angled view of unlocking tool 800. In particular, FIG. 8C shows user initiation portions 802, housing 804 and cavity 806. In addition, FIG. 8C shows a front opening 818. FIG. 8D illustrates a cross section view of housing 804 of unlocking tool 800. As show in FIG. 8D, housing 804 can include side openings 820. The side openings 820 can include a length a least several times greater than its width. FIG. 8E illustrates a front view of a user initiation portion 802 of unlocking tool 800.
It will be appreciated that the cables, connectors, unlocking tools, and portable electronic devices shown in FIGS. 3-8 are illustrative and that variations and modifications are possible. For example, certain modules can be removed, added, altered, changed, combined, etc. Illustratively, cable 300 can include a female receptacle connector instead of a male plug connector.
It will be further appreciated that the cables, connectors, unlocking tools, and portable electronic devices shown in FIGS. 3-8 can be adapted to be compatible with other types of connectors (e.g., Firewire connectors, Ethernet connectors, HDMI connectors, eSATA connectors, power connectors, display connectors, etc.). Also, as new connector types are developed, the aforementioned cables, connectors, unlocking tools, and portable electronic devices can also be adapted to be used with those types.
Examples of processes that can be used to assemble an unlocking tool and to use an unlocking tool will be described. FIG. 9 is a flow diagram of a process 900 for manufacturing and assembling an unlocking tool (e.g., unlocking tool 800 of FIG. 8A) according to one embodiment of the present invention. At block 902, housing 804 of unlocking tool 800 can be formed through a suitable injection molding process. At block 904, user initiation portions 802 can be machined through a suitable machining process. At block 906, an adhesive material, such as glue or epoxy, can be placed within channels 808 of housing 804.
At block 908, user initiation portions 802 can be moved through the side openings of housing 804. In particular, an end of each user initiation portion 802 can be passed horizontally or substantially horizontally through the side openings of housing 804. Illustratively, FIG. 10A shows user initiation portions 802 being moved through side openings 1002 of housing 804. As shown in FIG. 10A, the end of an individual user initiation portion that is first moved through the side openings is the end opposite to the end where the user initiation portion's pin is located.
At block 910, the user initiation portions 802 can be rotated and moved in a downward direction such that the user initiation portions can be vertically positioned. Illustratively, FIG. 10B shows user initiation portions 802 as the portions are rotated into a vertical position. Upon being fully rotated and moved downward, the user initiation portions can enter channels 808 of housing 804. In some embodiments, the user initiation portions can be “snapped” into place with channels 808. FIG. 10C shows user initiation portions fully rotated into the vertical position. By placing user initiation portions 802 into channels 808, the user initiation portions can be adhered to housing 804.
At block 912, a sufficient amount of time is permitted to pass in order for the adhesive material to set. At block 914, a lanyard can be threaded through the bottom openings of housing 804 in order to enable the unlocking tool to be conveniently carried. For example, a user can carry the unlocking tool by wearing the lanyard around his or her neck. As another example, a user can carry the unlocking tool by attaching the lanyard to a belt loop.
FIG. 11 is a flow diagram of a process 1100 for disengaging a male plug connector (e.g., male plug connector 400 of FIG. 4A) from a female plug connector using an unlocking tool (e.g., unlocking tool 800 of FIG. 8A) according to one embodiment of the present invention.
At block 1102, unlocking tool 800 can be slid over the cabling portion of a cable. For example, unlocking tool 800 can be moved over the cabling portion such that the cabling portion is placed within the cavity of unlocking tool 800. In some embodiments, the cabling portion can enter the cavity through the top of unlocking tool 800. The cabling portion can additionally exit the cavity through the front opening of unlocking tool 800. At block 1104, the unlocking tool can be moved along the cabling portion towards the male plug connector (e.g., male plug connector 400 of FIG. 4A) of the cable. Upon reaching the male plug connector, unlocking tool 800 can receive the male plug connector through the top of the tool.
At block 1106, the unlocking tool can be aligned with the male plug connector. In particular, unlocking tool 800 can be moved until portions of the user initiation portions (e.g., portions 816 of FIG. 8A) of the unlocking tool contact the male plug connector. Such contact can prevent the male plug connector from moving further into the cavity of unlocking tool 800, and can act to vertically align the access pathways of the male plug connector with the pins of unlocking tool 800. FIG. 12A, for example, shows unlocking tool 800 aligned with male plug connector 400. As shown in FIG. 12A, the male plug connector can be prevented from moving further into the cavity of unlocking tool 800 by the user initiation portions. As also shown in FIG. 12A, the access pathways of the male plug connector can be aligned with the pins of the user initiation portions of unlocking tool 800.
At block 1108, pressure or a force can be applied to the user initiation portions of unlocking tool 800. For example, a user can apply pressure using his or her thumb and index finger. Referring again to FIG. 12A, arrows 1202 and 1204 show the areas where pressure can be applied to the user initiation portions. The pressure can cause the pins of the user initiation portions to enter the access pathways of the male plug connector such that the hooks of the male plug connector can be disengaged from a female receptacle connector. Illustratively, FIG. 12B shows a cross section view of a male plug connector as the connector is being disengaged from a female receptacle connector. As shown in FIG. 12B, pins 812 of unlocking tool 800 can contact hooks 406 of male plug connector 400 such that the hooks are moved away from the inner cavities 606 of female receptacle connector 600. As a result, the male plug connector can be freely removed or disconnected from the female receptacle connector.
