## Background
BACKGROUND OF THE INVENTION
1. Technical Field
The present invention relates generally to high definition cable communications. More particularly, the present invention relates to a securely fastening high definition multimedia interface (HDMI) connector and related method of use. (HDMI, and the HDMI logo are trademarks or registered trademarks of HDMI Licensing, LLC).
2. Related Art
The onset of High Definition Televisions have led to the production of peripheral high definition (HD) components such as cable boxes, DVD players and mass storage devices that provide stored HD multimedia content. The HD components therefore necessitated the use of cables that are capable of transmitting data such as the digital visual interface (DVI) cable. The DVI cable had a shortfall of not providing an audio signal requiring an additional set of audio cables. The answer to the clutter of cables was to provide a new cable known as high definition multimedia interface that replaces the previous DVI cable. As shown in FIGS. 1-4, a standard high definition multimedia interface cable connector 1000 is commonly held onto a typical high definition multimedia interface receptacle 20 via friction interference fittings 22 unlike the previous DVI connectors that utilized two screws to secure the connectors. Moreover, a standard high definition multimedia interface receptacle 20 generally has fittings such as spring biased tabs 22 positioned in openings 25, wherein the tabs 22 are configured to fit into corresponding detents 1030 on an extension 1020 of a typical high definition multimedia interface plug 1000 to provide some interference between mated components and further assist in the retention of the standard high definition multimedia interface connector plug 1000 as mated within a typical high definition multimedia interface receptacle 20. However, the common configuration of standard high definition multimedia interface connector plugs 1000 is susceptible to poor performance due to structural and operable deficiencies; the standard plugs 1000 tend to come loose. Although the common spring biased tabs 22 provide some resistance to unwanted retraction of standard high definition multimedia interface plugs 1000, ordinary bumping the connector plugs 1000 or associated cables while cleaning, dusting or moving electrical devices often loosens the standard high definition multimedia interface connectors 1000 from proper mating positions with typical high definition multimedia interface receptacles 20. Moreover, the increasing use of wall mounted flat screen televisions, out of necessity or for the sake of aesthetics, has led to the increasing placement of high definition multimedia interface receptacles 20 that face downward. The downward orientation of the high definition multimedia interface receptacles 20 can further contribute to loose connections and signal loss if there is not sufficient friction between the plugs 1000 and the receptacles 20 to maintain contact as the associated standard high definition multimedia interface cable connectors 1000 fall off and become unplugged or otherwise disconnected due to the pull of gravity. Accordingly, a need exists for providing a releasably locking high definition multimedia interface plug.

DETAILED DESCRIPTION OF THE INVENTION
Although certain embodiments of the present invention will be shown and described in detail, it should be understood that various changes and modifications may be made without departing from the scope of the appended claims. The scope of the present invention will in no way be limited to the number of constituting components, the materials thereof, the shapes thereof, the relative arrangement thereof, etc., and are disclosed simply as an example of an embodiment. The features and advantages of the present invention are illustrated in detail in the accompanying drawings, wherein like reference numerals refer to like elements throughout the drawings.
As a preface to the detailed description, it should be noted that, as used in this specification and the appended claims, the singular forms “a”, “an” and “the” include plural referents, unless the context clearly dictates otherwise.
With reference to the drawings, FIG. 5 depicts a perspective view of an embodiment of a locking high definition multimedia interface plug 100 for connecting high definition multimedia interface cable 10 to high definition electronic components having standard high definition multimedia interface receptacles. Accordingly, the locking high definition multimedia interface plug 100 has an high definition multimedia interface connection end 35. The locking high definition multimedia interface plug 100 comprises a connector body or plug body 105, having an opening 130. The plug body 105 may include an extension 120. The opening 130 may be located on the extension 120 of the plug body 105. The plug body 105 can help retain a connected high definition multimedia interface cable 10. The locking high definition multimedia interface plug 100 may have a cable connection end 55. The locking high definition multimedia interface plug 100 comprises an actuator 165 configured to move a locking tab 150. The actuator may be associated with, or physically connected to, the locking tab 150, such that movement of the actuator 165 causes the locking tab 150 to move. Moreover, the actuator 165 may operate with a lock button 140 associated with, or operably coupled to, the plug body 105. The lock button 140 is configured to be manipulated by a user in an up, down, or sideways motion to work upon the actuator 165 and cause the actuator 165 to move the locking tab 150 between a first position 160 (see FIG. 8) and a second position 170 (see FIG. 9). The lock button 140 may be integrally formed with actuator 165, or may be separately attached to the actuator 165 and located to contact or otherwise configured to afford work upon the actuator in some operable manner. The lock button 140 may be depressible. In addition, a locking high definition multimedia interface plug 100 has a plug terminal contact 126.
Referring further to the drawings, FIG. 6 depicts a side view of an embodiment of a locking high definition multimedia interface plug 100 mated to a receptacle 20 (shown in FIG. 7), the receptacle 20 may be secured to a housing 5, for example, by a mounting screw 7. The housing 5 may be any physical component of a high definition electrical device. For example, the housing may be the outer casing of a flat-screen HD television, the shell of a cable TV box, or the covering of a DVD player. The high definition multimedia interface connection end 35 of the locking high definition multimedia interface plug may be plugged into the receptacle to facilitate a connection and allow transmission of electronic communications through the cable 10 connected to the cable connection end 55 of the locking high definition multimedia interface plug. An extension 120 may extend from the plug body 105 and be configured to be inserted into the receptacle 20. The lock button 140 is utilized to help securely fasten the locking high definition multimedia interface plug 100 to the receptacle 20 mounted in the housing 5.
With continued reference to the drawings, FIG. 7 depicts a partial cutaway side view of an embodiment of a locking high definition multimedia interface plug 100 mated with a receptacle 20. The plug terminal contacts 126 are configured to mate with a receptacle port contact 26 of the receptacle 20. A typical high definition multimedia interface receptacle, as described previously, may commonly have a sidewall opening 25 with a spring biased tab 22 (as shown in FIG. 1). The sidewall opening 25 is located on the outer surface of the receptacle and generally permits the spring biased tab 22 to protrude somewhat into a detent(s) of a standard high definition multimedia interface plug (see FIGS. 1-4). Hence, when the spring biased tab(s) 22 protrudes into the typical detent(s) of a standard high definition multimedia interface plug, some mechanical interference between the parts is created to help retain the standard plug in mated position with the receptacle 20. However, the typical shape of the spring biased tab 22 and the associated forces of the interference fit of the tab 22 with openings or detents of a standard high definition multimedia interface plug are often insufficient to securely retain the standard high definition multimedia interface plug in an appropriate mating position with the receptacle 20. Accordingly, embodiments of a locking high definition multimedia interface plug 100 are configured such that the typical spring biased tab 22 of a standard high definition multimedia interface receptacle can protrude into the opening 130 of the body 105 helping to secure the locking high definition multimedia interface plug 100 to the receptacle 20. Thus, the inclusion of a locking tab 150 of the present invention facilitates a secure mating position when the locking high definition multimedia interface plug 100 is releasably mounted to a standard high definition multimedia interface receptacle.
The locking tab 150 of a locking high definition multimedia interface plug 100 may be configured to be moved into a locked position 161 (as shown in FIG. 7), wherein the locking tab 150 may be located so as to operably protrude into and engage the typical sidewall opening 25 of a receptacle 20. The shape of the locking tab may be configured to substantially hinder and/or stop the retraction of the locking high definition multimedia interface plug 100 from a mated position with the receptacle 20 in a locking, but be releasable simply by the provision of a motive force acting on the actuator 165 of the plug 100. The configuration of the locking high definition multimedia interface plug 100 may necessitate the movement of the locking tab 150 out of the opening 25 before the locking high definition multimedia interface plug may be retracted. However, tab 150 embodiments may be provided wherein the tabs 150 are configured to slip, move, break away, or otherwise facilitate release from a locked position 161 when sufficient force is placed upon the tabs 150. Hence, the tabs 150 may release to prevent damage from occurring to the high definition multimedia interface receptacle as a result of the force. With respect to FIG. 8, various configurations of locking tab embodiments 150a1, 150a2, and 150a3 are shown. A locking tab embodiment 150a1 may include a ramped rear edge 158a1 having a reverse incline. The reverse incline may be angled such that sufficient force may cause the rear edge 158a, to slip out from engagement with the opening 25 of a receptacle 20 (see FIG. 7). Nevertheless, the rear edge 158a1 may be shaped so that typical forces due to gravity, dusting, cleaning, moving electrical devices, or otherwise bumping a cable 10 (see FIGS. 5-6) or high definition multimedia interface plug 100 will not be sufficient to break away the locking tab 150a1. But a substantial jerk on the cable 10 or a large push against the mated plug 100 will cause the tab 150a1 to release so that the receptacle 20 is not damaged as a result of the force from the jerk or push.
Referring further to FIG. 8, embodiments of the locking tab 150 are configured to permit easy insertion of the plug 100 into the receptacle 20. For example, a tab 150 may have rounded, beveled, or ramped forward edges 157 permitting unidirectional movement of the tab 150 into docking engagement with the receptacle 20. The plug 100 may be inserted into a receptacle 20 and the ramped forward edges 157 may allow the locking tabs 150 to slidably snap into a locked position 161 when the extension 120 is inserted such that the tab(s) 150 securely protrude into the opening(s) 25 of the receptacle 20 (see FIG. 7). Accordingly, a locking tab embodiment 150a1 may include a ramped edge 157a1 having a forward incline permitting the tab 157a1 to slidably snap into engagement with the opening 25 of the receptacle 20. However, as shown and described above the rear edge 158a1 may be ramped in a reverse direction and may have a steeper angle of incline making it harder for the tab 150a1 to slide in the reverse direction. Other embodiments of the locking tab 150, such as embodiments 150a2 and 150a3, may also include rear edges or impedance surface(s) 158 configured to obstruct movement in the opposite releasing direction while the tab 150 is snapped into the opening 25 of the receptacle 20. For instance, tab embodiment 150a2 includes a verticle rear edge 158a2 designed to hinder movement in the reverse direction when the tab 150a2 is in a locked position 161 (see FIG. 7). However, the transition between the ramped forward edge 157a2 and vertical rear edge 158a2 may be rounded so that the tab 150a2 may move if sufficient force is provided in the reverse direction. Tab embodiment 150a3 includes a forward inclined rear edge 158a3 designed to hinder movement in the reverse direction when the tab 150a3 is in a locked position 161. The tab embodiment 158a3 may be designed to snap off or break away if sufficient force is provided in the reverse direction. Thus, embodiments of a locking tab 150 may facilitate release from a locked position 161 when sufficient force is inflicted upon the tab 150.
The locking tab 150 may be moved into and/or may be moved out of the typical opening 25 of a receptacle 20 by operation of an actuator 165. For example, a lock button 140 may be configured to be depressed, or made to slide forward and backward, to slide side-to-side, or otherwise set in motion to act upon the actuator 165, which, in turn, moves the locking tab 150. For instance, the lock button 140 may be used to move a leaf-spring type actuator 165 downward, as shown in FIG. 9, and also cause the locking tab 150 to move downward into the opening 130 of the extension 120 and out of the opening 25 of the receptacle 20 to thereby unlock the plug 100 from the receptacle 20. However, it should also be appreciated that the configurations of locking high definition multimedia interface plug embodiments, to be described later, also permit maneuvering of the lock button 140 to work upon the actuator 165 and thereby move the locking tab 150 into an interference position within the sidewall opening 25 of the receptacle 20.
With continued reference to FIGS. 1-8, when mating a locking high definition multimedia interface plug 100 to a receptacle 20, a user may grip the plug body 105 and advance, push or otherwise insert the connection end 35 of the plug 100 into a corresponding a receptacle 20. The receptacle 20 may facilitate electrical communication with other electrical components. For example a circuit connection end 28 (see FIG. 7) of the receptacle 20 may include contacts or leads that make possible the communication of electromagnetic signals to various electronic devices.
Embodiments of locking high definition multimedia interface plugs, such as plug 100, may utilize a movable actuator 165 to help position a locking tab 150 into an interfering location with respect to a receptacle 20. Referring to FIG. 9 a locking high definition multimedia interface plug 100 is shown having an actuator 165 located in a first position 160. A first position 160 of the actuator 165 may correspond to a locked position 161 when the plug 100 is mated with a receptacle 20. When the actuator 165 is located in a first position 160, the locking tab 150 may be biased to protrude from the opening 130. A lock button 140 may be operably associated with the plug body 105 and the actuator 165 may be operably associated with the lock button. Accordingly, the locking tab 150 operably associated with the actuator 165, may contact, engage, or otherwise interfere with the typical sidewall opening 25 of a standard high definition multimedia interface receptacle 20 and thereby help to restrict the unplugging the locking high definition multimedia interface plug 100 from the receptacle 20.
The actuator 165 may also be movably locatable in a second position 170, wherein the associated locking tab 150 does not protrude from the opening 130 of the body, as depicted in FIG. 10. For example, when the actuator 165 is in a second position 170, the locking tab 150 may be positioned within the opening 130 of the body extension 120 so that it does not extend away from the opening 130. A second position 170 of the actuator 165 may correspond to an unlocked position 171 when the plug 100 is mated with a receptacle 20. Hence, when the actuator 165 is in a second position 170, the locking tab(s) 150 may not contact or otherwise interfere with other physical components, such as sidewalls or opening(s) 25 of a receptacle 20, in proximate association with the extension 120. It should be appreciated that when locking high definition multimedia interface plug embodiments, such as plug 100, are mated to a receptacle 20, unlocking and efficiently retracting the plug 100 from the receptacle 20 may involve the operable positioning of the actuator 165 into a second position 170, thereby eliminating the interference between the impedance surfaces 158 of the locking tab(s) 150 and the sidewall opening(s) 25 of the receptacle 20.
A locking high definition multimedia interface plug embodiment 100 may comprise a locking tab 150 movably locatable within an opening of a plug body 105, such as opening 130 in body extension 120. Moreover the locking high definition multimedia interface plug 100 may comprise an actuator 165 operably configured to move the locking tab 150 into a locked position 161, wherein said locking tab 150 protrudes from the opening 130 of the extension 120 to securely engage an high definition multimedia interface receptacle 20. Moreover, the actuator 165 may be operably configured to move the locking tab 150 into an unlocked position 171 (see also unlocked position 671 of FIG. 39), wherein said locking tab 150 does not protrude or extend away from the opening 130.
FIG. 11 depicts an end view of an embodiment of a locking high definition multimedia interface plug 100. The locking high definition multimedia interface plug 100 may comprise one or more locking tabs, such as locking tabs 150a and 150b. As depicted, the locking tabs 150a-b are protruding from the extension 120. Hence, the actuator 165 (not shown) may be located in a first position 160 (see FIG. 9). Whenever, the tabs 150a-b are located so as to interfere with a corresponding receptacle 20, then the corresponding location of the locking high definition multimedia interface plug 100 components may be attributable to a locked position 161. The tabs 150a-b must therefore be moved to an unlocked position 171, a position essentially eliminating interference with a receptacle 20, for the locking high definition multimedia interface plug 100 to be efficiently retracted from a mated position with the receptacle 20. A user may grip the plug body 105 and depress the lock button 140 to work upon the actuator 165 and move the locking tabs 150a-b out of sight within the opening 130 (not shown) of body extension 120. Additionally, embodiments of a locking high definition multimedia interface plug 100 may comprise an inner section 180, the end of which being shown in FIG. 11. The inner section 180 also may include plug terminal contacts 126 configured to physically and electrically contact corresponding receptacle port contacts 26 (see FIG. 7) of a typical high definition multimedia interface receptacle 20. Plug terminal contacts 126 are further delineated in FIGS. 41-42. Accordingly, a locking high definition multimedia interface plug embodiment 100 may include 19 terminals, as in either a typical Type A or a typical Type C high definition multimedia interface standard connector (see FIG. 41) or 29 terminals that are typically present in a standard Type B high definition multimedia interface connector (see FIG. 42). The inner section 180 may be integrally formed with the extension 120, may be separately joined to the extension 120, or may be removably secured within the extension 120. Moreover, the plug terminal contacts 126 may be integrally formed as part of the inner section 180, may be separately joined to the inner section 180, or may be removably secured to the inner section 180. The inner section 180 may be formed of conductive materials or may be formed of a dielectric material.
An embodiment of a body extension member 220 that may be used in a High Definition Multimedia Interface (high definition multimedia interface) communication applications is shown in FIGS. 12-16. The extension 220 may have at least one opening 230 (as shown, an extension 220 preferably includes two openings 230). The extension 220 may be configured to fit into an high definition multimedia interface receptacle, such as receptacle 20, or may be configured to be used with any other receptacle that relies upon a friction or tolerance fit to retain the extension 220 within the receptacle. The high definition multimedia interface standard uses a conductive surface for the extension 220, but in other applications the extension 220 may be an insulator. The extension 220 may be a metal that is stamped or otherwise formed into the desired shape or may be a conductive polymer that is injection molded or extruded. The extension 220 may be formed of dimensionally stable materials that could be made conductive if required to be used in connectors.
An extension member 220 may be retained somewhat within a plug receptacle, such as receptacle 20, by friction due to close tolerance with the receptacle. However, with respect to a locking high definition multimedia interface plug embodiments, such as plug 100, the extension 220 may include a releasable protrusion, or locking tab 250 that may engage an opening 25 of a receptacle 20, and prevent unintended release. As shown in FIG. 13, the locking tabs 250 may be configured to reside with the openings 230 of the extension member 220. Furthermore, an high definition multimedia interface connector end 35 of the extension 220 may be inserted into an high definition multimedia interface receptacle 20 and may be selectively locked or secured into the receptacle with the use of an actuator 265. The actuator may be worked upon by a lock button 240 operated by a user. The user operates the lock button 240 either by compression or sliding until it is moved sufficiently to work upon the actuator to help secure the plug 100. To secure the high definition multimedia interface type plug extension embodiment 220 into a plug receptacle the extension 220 includes a locking tab 250 that may be biased or moved by the actuator 265.
The actuator 265 has a first position 260, as shown in FIG. 14, where the lock button 240 is slidingly moved to work upon the actuator 265 so that the locking tab 250 is biased to protrude from said opening 230 of said extension 220. The actuator 265 has a second position 270, as shown in FIG. 15, where the lock button 240 is slidingly moved to cause the actuator 265 to move the locking tab 250 to be positioned substantially within said at least one opening 230 of said extension 220. The locking tab 250 may also be configured to be resiliently biased into a locked position 161, corresponding to the first position 260 of the actuator 265, so that that the lock button 240 may be compressed moving the actuator relative to an unlocked position 171 and release the locking tab 250 once resiliently engaged into a receptacle 20, such as by maneuvering the locking tab 250 out of the sidewall opening 25 of a receptacle 20 (see FIG. 7).
As shown in FIG. 12, the extension embodiment 220 may further include sub components such as an inner section 280 positioned within said extension member 220. The extension 220 may be a one-piece extension component that includes molded in or insertable terminal ends, such as plug terminal contacts 126 (see FIG. 11). The inner section 280 may also contain a guide portion 285 (see FIGS. 14-15) that may be configured as a channel, pathway or groove within the inner section 280 that may be configured to facilitate linear sliding or other guided movement of the actuator 265. The inner section 280 may be any structurally rigid material such as an injection molded plastic that would allow the introduction of the terminals, such as terminals 126.
FIG. 15 is an exploded view of an extension 220 of embodiments of a locking high definition multimedia interface plug, such as plug 100, and includes an actuator 265 having a proximate end 266 and a distal end 267, wherein the proximate end 266 may be attached to, or otherwise operable with said lock button 240, and wherein the distal end 267 may be attached to, or otherwise operable with said locking tab 250. The actuator 265 may be produced from a resilient material that may be biased to a desired orientation. Moreover, the actuator 265 material could be made of a spring-type steel or a resilient polymeric material that is either stamped or injection molded. When the button 240 works upon the actuator 265, a ramp 290 may be positioned on said inner section 280. The movement of said locking tab 250 against said ramp 290 may be resiliently biased to protrude through said opening 230 on said extension 220 when said lock button 240 is in the first position 260. A depression 291 may be formed within said inner section 280 and may be configured to accept said locking tab 250 when said lock button 240 is in the second position 270 to allow release of the extension 220 from an high definition multimedia interface receptacle.
As shown in FIGS. 17-19, an locking high definition multimedia interface plug embodiments may include a single large opening 231 of an extension 221. An actuator 269 structure having adjoined locking tips 251 may be located in a first position 260 such that the locking tips 251 protrude above the surface of the extension embodiment 221. Moreover, the actuator 269 may be located in a second position 270 such that the locking tips 215 reside substantially within the large opening 231 of the extension 221.
As shown in FIGS. 20-23, another locking high definition multimedia interface plug embodiment 300 is depicted. The connector plug 300 may comprise a diving hinge lock button 340 operable with a plug body 300. The hinged lock button 340 may be attached to the plug body 305 or integrally formed with the plug body 305 such that the lock button 340 attaches to the plug body 305 in the general vicinity of a location 342. The lock button 340 is coupled to the actuator 365. A user may operate the lock button 340 by pressing the button 340 toward the actuator 365. The lock button 340 is configured such that motive force provided by a user transfers from the lock button 340 to the actuator 365 to move a locking tab 350. When the actuator 365 is in a first position 360 the locking tab is biased to protrude from the extension 320. Accordingly, a user can insert the high definition multimedia interface connector end 335 into a receptacle and assist the action of locking through the hinged operation of the lock button 340. Surface features 347, such as ridges, may be provided on the exterior surface of the lock button to correspond to a better user interface during operation. The lock button 340 may contact or otherwise interact with the actuator 365 at a juncture 345. A cable 10 is connected to the locking high definition multimedia interface plug 300 at a cable connector end 355.
FIGS. 24-27 show another plug embodiment that includes a sliding actuator 465 that is coupled at a proximate end 466 to a lock button 440. The sliding actuator 440 may engage and lift the inwardly biased locking tab 450 of the plug body extension 420. The locking tab 450 may be attached to or be integral with the body extension 420. The tab 450 may be formed to be normally downwardly biased having a resilient member 410 that is converted to an upward bias by movement of the distal end 468 of the sliding actuator 465 underneath the locking tab 450 when the lock button 440 is moved to the first position 460. The placement of the sliding actuator 465 beneath the locking tab 450 causes the locking tab 450 to bend outward to protrude from the opening 430 of the body extension 420. When the actuator 465 is in the second position, the locking tab my be biased downward through the opening of the body extension 420 and into a depression 492 or portion of slide track 485.
The plug body extension embodiment 420 includes a slide track 485 formed in an inner section 480 similar to that shown in FIGS. 14-16, but without the inclusion of a ramp 290. In FIGS. 14-16 a ramp 290 is formed in the inner section 280, wherein said locking tab 250 is separate from the extension 220 and said locking tab 250 is resiliently biased or pushed outwards through said opening 230 in the extension 220 by said ramp 290 when the lock button 240 is slid into the first position 260.
In another embodiment, an extension 520 of a locking plug, as shown in FIGS. 28-31, may be structured to operate somewhat in contrast to embodiments previously discussed. The extension 520 includes at least one locking tab 550 that angularly protrudes and is biased away from opening 530 of the extension 520 in a direction away from the high definition multimedia interface connection end 35 of the plug. The opening 530 of the extension 520 may include a ramped edge 524. When an actuator 565 is in a first position 560 (see FIG. 29), the extension 520 may be secured within a receptacle 20 in a locked position (see FIG. 7) since said locking tab 550 is biased upward into an opening 25 of the receptacle. Accordingly, the locking tabs 550, being angled away from the high definition multimedia interface connection end 35, facilitate snap locking of the tabs 550 into the receptacle openings 25 when the extension 520 is inserted into a receptacle 20. The angled geometry of the snap locking tabs 550, being substantially opposite to the direction of insertion, prevents the unwanted retraction of locking high definition multimedia interface plug embodiments once snapped into a mated position with the receptacle 20. However, the tabs 550 and related components are configured to break away or otherwise release when a substantial amount of force is applied to the snap connection, such as by a retractive jerking of the cable 10. A lock button 540 is provided to move the actuator 565 to a second position 570, as shown in FIG. 31. When the actuator 565 is moved to the second position 570, the locking tabs 550 contact edge 537 of the opening 530 thereby causing the locking tabs 550 to be pushed downward and retracted and moved beneath opening 530. When the locking tabs 550 are retracted within opening 530 the plug is in an unlocked position 571 and a user may retract the plug from a receptacle 20.
A further locking high definition multimedia interface connector plug embodiment 600 is depicted in FIGS. 32-39. This embodiment employs a sliding body lock button 640 operably coupled to a plug body 605 configured to retain a cable 10. The sliding body lock button 640 may work upon an actuator 665 to move one or more locking tabs 650 such that they protrude from or reside within top surface 624 of an extension member 620. The sliding body lock button 640 may include an inner spring 643 which tends to drive the locking button toward the plug body 605. When the sliding body lock button 640 is driven to the plug body 605 by spring 643, the actuator 665 is in a first position 660 and acts to place the locking tabs 650 into a biased position protruding from the extension 620 (see FIGS. 33-34). This protruding position of the locking tabs 650 corresponds to a locked position 661 of the locking high definition multimedia interface plug 600 when the plug is mated with a receptacle 20. When the plug 600 is in the locked position, the plug 600 is securely but releasably retained within the receptacle 20.
A user may slide the sliding body lock button 640 away from the plug body 605 and compress the inner spring 643. Moreover, when the sliding body lock button 640 is slid toward the extension it engages the actuator 665 to move to a second position 670. When the actuator is in the second position 670, the locking tabs 650 may reside within the opening 630 of the extension 620 and not protrude from the top surface 624 of the extension 620 (see FIGS. 37-38). When the locking tabs 650 do not protrude from the extension 620 they do not interfere with the receptacle 20 permitting the locking high definition multimedia interface plug to be easily retracted and unplugged from the receptacle 20.
FIG. 40 depicts a perspective view of another locking high definition multimedia interface plug embodiment 700 prior to mating with a receptacle 20. The locking plug 700 includes a receptacle-shaped plug body 705 configured to mate with and be inserted into the receptacle 20. A substantial portion of the plug body 705 is shaped having a complimentary form relative to a corresponding mating receptacle 20. An opening 730 is positioned in the body 705. An actuator 765 is configured to move locking tabs 750 into and/or out of the opening 730 of body 705. The placement of the tabs 750 out of the opening 730 corresponds to a first position 161 (see FIG. 9). The placement of the tabs within the opening 730 corresponds to a second position 171 (see FIG. 10). When the high definition multimedia interface connection end 735 is inserted into the receptacle 20, the locking tabs 750 may slide along a top interior surface of the receptacle 20 until the plug 700 is inserted to a point where the locking tabs can engage the typical openings 25 of the receptacle. When operably plugged-in or mounted to the receptacle 20, the locking high definition multimedia interface plug 700 is firmly held by engagement of the locking tabs 750. Moreover, the spring biased tabs 22 releasably engage the opening 730 of the locking plug 700 when the plug 700 is operably mounted to the receptacle. The plug 700 may be released, unmounted, or unplugged from the receptacle 20 by moving the actuator 765 to in turn move the locking tabs 750 out of engagement with the openings 25 of the receptacle 20.
Embodiments of a locking high definition multimedia interface plug, such as plugs 100, 300, 600, and 700 may be configured as shown in FIGS. 41 and 42 to be inserted into a high definition multimedia interface receptacle corresponding to Type A, B or C high definition multimedia interface plug standards. Moreover, embodiments of a locking plug 100/300/600/700 may have a locking means to securely but releasably plug into a high definition multimedia interface receptacle, such as receptacle 20, as discussed above. The locking means may include a locking tab 150/250/251/350/450/550/650/750 configured to interact with the receptacle 20 to retain the plug 100/300/600/700. Moreover, the locking means may include any movable feature configured to operably interfere with a portion of a typical opening 22 (see FIGS. 1-4) of an high definition multimedia interface receptacle 20 to securely retain the plug 100/300/600/700 to the receptacle 20. The locking means may move into locking position through operation of an actuator 165/265/365/465/565/665/765.
A method of compliantly locking a plug 100/200/300/600/700 into a receptacle 20 is depicted in reference to FIGS. 5-42 and may comprise the steps of: providing a locking high definition multimedia interface 100/300/600/700 including a plug body 105/305/605/705. The plug body may have an extension 120/220/221/320/420/520/620 configured to be inserted into a high definition multimedia interface receptacle, such as receptacle 20. Accordingly, the each of the extension embodiments, such as extensions 120/220/221/320/420/520/620, may be configured to be an operable extension of any plug body embodiment. The plug 100/300/600/700 also includes an actuator 165/265/365/465/565/665/765 operable with the body 105/305/605/705. In addition, the locking high definition multimedia interface plug 100/300/600/700 includes a locking tab 150/250/251/350/450/550/650/750 coupled to the actuator 165/265/365/465/565/665/765, wherein the locking tab 150/250/251/350/450/550/650/750 is configured to movably protrude from an opening 130/230/330/430/530/630/730 of the body 105/305/605/705. The plug 100/300/600/700 may be removably secured to the receptacle, such as receptacle 20, by biasing the locking tab 150/250/251/350/450/550/650/750 sufficiently to protrude from the opening 130/230/330/430/530/630/730 of the body 105/305/605/705, or operable body extension 120/220/221/320/420/520/620, to engage the receptacle 20 and releasably lock the body 105/305/605/705 into the receptacle 20.
Embodiments of a locking high definition multimedia interface plug 100/300/600 may utilize an actuator 165/265/365/465/565/665/765 to bias the locking tab 150/250/251/350/450/550/650/750. Accordingly, the locking tab 150/250/251/350/450/550/650 may be biased by working on the actuator 165/265/365/465/565/665/765 to move the actuator 165/265/365/465/565/665/765 and move the locking tab 150/250/251/350/450/550/650/750.
Removal of the embodiments of a locking high definition multimedia interface cable connector plug 100/300/600/700 may comprise the steps of: unbiasing the locking tab 150/250/251/350/450/550/650/750 sufficiently to prevent protrusion of the locking tab 150/250/251/350/450/550/650/750 from the opening 130/230/330/430/530/630/730 of the body 105/305/605/705, or operable body extension 120/220/221/320/420/520/620, to unlock the plug 100/300/600/700 from the high definition multimedia interface receptacle, such as receptacle 20.
Embodiments of a locking high definition multimedia interface plug 100/300/600 may utilize an actuator 165/265/365/465/565/665/765 to unbias the locking tab 150/250/251/350/450/550/650/750. Accordingly, the locking tab 150/250/251/350/450/550/650/750 may be unbiased by working on the actuator 165/265/365/465/565/665/765 to move the actuator 165/265/365/465/565/665/765 and move the locking tab 150/250/251/350/450/550/650/750.
Certain embodiments may utilize the operation of a lock button 140/240/340/440/540/640/740 to work on the actuator 165/265/365/465/565/665/765 and accomplish the biasing or unbiasing of the locking tab 150/250/251/350/450/550/650/750 sufficiently to enable protrusion or prevent protrusion of the locking tab 150/250/251/350/450/550/650/750 from the opening 130/230/330/430/530/630/730 of the body 105/305/605/705, or operable body extension 120/220/221/320/420/520/620, to lock or unlock the plug 100/300/600/700 from the high definition multimedia interface receptacle, such as receptacle 20.
