DETAILED DESCRIPTION

[0013] It may be the case that a connector requires a user to depress a clip to release the connector from a receptacle. This can limit the allowable positioning of receptacles, as clearance should be provided for the user’s hand to depress the clip.

[0014] A "push-push” mechanism in a receptacle includes a slider to eject a connector from the receptacle in response to the user pushing the connector further into the receptacle. The slider depresses the connector’s clip to release the connector from the receptacle. The mechanism may further include a rotational cam to selectively apply an ejecting force to the slider and connector. This allows for receptacle placement to be selected without the consideration for user finger clearance often needed for the user to manually depress the clip. Further, and the connector may be a standard connector and the receptacle may conform to the same external geometric constraints as a standard receptacle, so that existing cables with attached connectors can be used. [0015] As shown in FIGs. 1A to 1 C, an example device 100 includes a receptacle 102 and a slider 104 disposed in the receptacle 102. The device 100 may be installed on a computing device, such as a desktop computer, notebook computer, server, router, switch, or similar. The receptacle 102 may be shaped and sized to fit a connector 110, such as a connector used for network communications (e.g., Ethernet). The receptacle 102 and connector 1 10 may conform to Registered Jack (RJ) 45, RJ45s, 8 position 8 contact (8P8C), or similar standard.

[0016] The receptacle 102 may be defined by a body 106, such as a housing that includes an opening at one end. An electrical contact 108 may be disposed within the receptacle 102. The electrical contact 108 may include an exposed metal contact that is fixed to the body 106. A wire, circuit, or similar electrical element may be connected to the electrical contact 108. Any suitable number of electrical contacts 108 may be used.

[0017] The receptacle 102, which may be referred to as a port, is shaped to receive a connector 110, which may be referred to as a plug or jack. The receptacle 102 provides an electrical connection with the connector 110 when the connector 1 10 is inserted into the receptacle 102. For example, an electrical contact 112 positioned at a body 1 14 of the connector 102 may be brought into physical contact with a corresponding electrical contact 108 of the receptacle 102 when the connected 1 10 1s inserted into the receptacle 102. The connector 1 10 may be slid into the receptacle 102 up to a connection point 1 16, at which the electrical connection is made. The receptacle 102 is shaped and sized so that the connector 110 may be slid past the connection point 1 16. The electrical contacts 108, 1 12 may be flexible, to allow the connector 110 slide past the connection point 116.

[0018] The connector 1 10 includes a clip 1 18, which may engage with a feature at the receptacle 102 to secure the connector 110 in the receptacle 102. The clip 118 may be resilient, so that a user can manually depress the clip 1 18 to remove the connector 1 10 from the receptacle 102. For example, depressing the clip 1 18 may disengage the clip 118 from the securing feature at the receptacle 102 and allow the clip 1 18 to slide out of the receptacle 102.

[0019] The slider 104 is disposed in the receptacle 102. The slider 104 includes a leg 120 to depress the clip 118 of the connector 110 when the connector 1 10 is pushed into the receptacle 102 past the connection point 116. That is, the leg 120 may extend towards the opening of the receptacle 102 and be aligned with the clip 1 18 of the connector 110. The leg 120 may be sufficiently short, so as to not press against the clip 118 or to just touch the clip 1 18 when the connector 1 10 is inserted up to connection point 1 16. However, if the connector 1 10 is pressed further into the receptacle 102, then the leg 120 of the slider 104 may press against the clip 1 18 of the connector 110 to deflect the clip 1 18. The leg 120 may press the clip 1 18 at a point of contact 122 on the clip 1 18. Deflection of the clip 1 18 may disengage the clip 1 18 from the securing feature at the receptacle 102, so that the connector 110 may be withdrawn from the receptacle 102.

[0020] The slider 104 may be moveable within the receptacle 102, so that the slider 104 may hold the clip 1 18 in the depressed position while the connector 1 10, and thus the clip 1 18, is withdrawn from the receptacle 102. The slider 104 may be spring-loaded to follow withdrawal of the connector 1 10. For example, as will be discussed in further detail below, a bias mechanism may be provided to apply an ejecting force to the slider 104.

[0021 ] In operation, following the sequence of FIGs. 1 A to 1 C, the connector 1 10 is inserted into the receptacle 102, as show in FIGs. 1 and 1 B. The connector 1 10 reaches the connection point 1 16 and the electrical contact 112 of the connector 110 contacts the electrical contact 108 of the receptacle 102 to make the electrical connection, as shown in FIG. 1 B. At this point, the clip 1 18 of the connector 110 may engage with the body 106 of the receptacle 102 to secure the connector to the receptacle 102. Then, at a later time, the connector 1 10 may be pressed further into the receptacle 102, past the connection point 116, so that the leg 120 of the slider 104 contacts the clip 118 of the connector 110 and depresses the clip 118, as shown in FIG. 1 C. Depression of the clip 118 may disengage the clip 118 from the body 106 of the receptacle 102, so that the connector 110 may be removed from the receptacle without the user having to manually press the clip 118. The slider 104 may be biased to move with the connector 110 as the connector 110 is withdrawn, so as to continue to depress the clip 118.

[0022] FIGs. 2A to 2E show an example device 200 that includes a receptacle and a slider disposed in the receptacle, where the slider assists in ejection of a connector inserted into the receptable. The description of the device 100 may be referenced for details not repeated here, with like terminology and like reference numerals denoting like components. Electrical contacts are omitted from FIGs. 2A to 2E for sake of clarity.

[0023] The device 200 includes a body 202 that defines a receptable 204. The body 202 includes a catch 206 that is positioned inside the receptacle 204.

[0024] The catch 206 may be a lip, projection, or similar feature on the inside of the body 202. The catch 206 is positioned to engage a resilient clip 208 of a connector 210 to secure the connector 210 inside the receptacle 204. The clip 208 of the connector 210 may include a protrusion 212 shaped to slide past the catch 206 as the connector 210 is inserted and to secure the connector 210 after the connector 210 is inserted. The protrusion 212 may have a sloped surface that contacts the catch 206 and causes the clip 208 to bend during insertion. The protrusion 212 may further have an opposing surface that abuts the catch 206 and prevents mere pulling of the connector 210 from removing the connector 210 from the receptable 204. When the connector 210 is inserted, the resilient clip 208 may extend outside of the receptable 204 to allow an external force, such as a force applied by a user’s finger, to bend the resilient clip 208 to disengage the protrusion 212 from the catch 206 to release the connector 210. [0025] The device 200 further includes a slider 214 disposed in the receptacle 204. The slider 214 is positioned to bend the resilient clip 208 of the connector 210 to force the clip 208 to disengage from the catch 206 when the connector 210 is over-inserted into the receptable 204, that is, past a point of engagement 218 (FIG. 2C) of the protrusion 212 and the catch 206. The slider 214 may include a leg 216 extending therefrom to contact the clip 208. The leg 216 may have a contact surface 220 that is angled to match a corresponding contact surface 222 of the clip 208 of the connector 210. The contact surface 220 is angled to transfer linear inward motion of the clip 208, as the clip 208 moves with the connector 210, into bending deflection of the clip 208.

[0026] The device 200 further includes a bias mechanism 230 disposed in the receptacle 204. The bias mechanism 230 is positioned to apply an ejecting force to the slider 214, in response to the connector 210 being inserted into the receptable 204 past the point of engagement 218 of the resilient clip 208 to the catch 206. The ejecting force urges the slider 214 to remain in contact with the clip 208 to keep protrusion 212 of the clip 208 disengaged from the catch 206 while pushing the connector 210 out of the receptacle 204.

[0027] The bias mechanism 230 may include a spring 232 positioned between the body 202 and the slider 214. The spring 232 may be a coil spring, a cantilevered spring, a resilient or elastic member, such as a hollow resilient ball, or similar. The spring 232 provides the ejecting force to the slider 214. Any suitable number of springs 232 may be provided.

[0028] The slider 214 may be slidable between a secured position (FIG. 2C) and released position (FIG. 2A). In the secured position, the leg 216 of the slider 214 does not depress the clip 208 of the connector 210. Further, the spring 232 may be compressed or otherwise store energy and the slider 214 is held against movement by the bias mechanism 230. The slider 214 is biased towards the released position in a controllable manner by the bias mechanism 230. The bias mechanism 230 may selectively lock the slider 214 in the secured position (FIG. 2C). [0029] In the released position (FIG. 2A), the bias mechanism 230 has released the slider 214 and to allow the bias force of the spring 232 to urge the slider 214 toward the connector 210. The leg 216 of the slider 214 depresses the clip 208 of the connector 210. Further, the slider 214 is free to move to follow the connector 210 as the connector 210 is withdrawn or pushed out of the receptable to ensure that the clip 208 remains depressed until past the catch 206.

[0030] The bias mechanism 230 may include a cam 234 that engages a cam stop 236 that forms part of the body 202 or is affixed to the body 202. The cam is further coupled to the slider 214. The cam 234 may operate to toggle in a push-push action to alternately lock and unlock the slider 214 in the secured position (FIG. 2C), in response to presses at a protrusion 238 of the cam mechanism 234 by the connector 210. To expose the cam mechanism 234 to the connector 210, the protrusion 238 of the cam mechanism 234 may extend through a hole 240 in the portion of the body 202 or other structured that defines the cam stop 236.

[0031 ] The cam mechanism 234 and cam stop 236 may have complementary cam surfaces that mutually abut to configure the cam mechanism 234 to lock the slider 214 in the secured position. The cam mechanism 234 and/or cam stop 236 may further have slots or other structure that allow the cam mechanism 234 to expand and contract laterally (left and right in the figures) to free the cam mechanism 234 and allow the slider 214 to move into the released position (FIG. 2A) under force of the spring 232. That is, the cam mechanism 234 is coupled to the slider 214 and is positioned to contact the connector 210, for example at the protrusion 238, to alternately lock and unlock the slider 214 in response to a push of the cam mechanism 234 from the connector 210. The cam mechanism 234 is thus switchable or toggleable between locking the spring 232 and releasing the spring 232 to push the slider 214. [0032] The cam mechanism 234 may be coupled to the slider 214 by way of abutting surfaces that may include a protrusion and recess structure, as shown at 242, that prevent the cam mechanism 234 from escaping. The slider 214 may include a base portion 244. The spring 232 may be captured between one side of the base portion 244 and the body 202, and the cam mechanism 234 may be captured between an opposite side of the base portion 244 and the body 202.

[0033] Spring securement structures, such as posts 246, 248 may be positioned on the body 202 and the body-side of the base portion 244 of the slider 214 to secure the spring 232 in place. For example, the ends of a coil spring 232 may fit over the posts 246, 248 to prevent the spring 232 from escaping.

[0034] In operation, the connector 210 is inserted into the receptable 204, as shown in FIGs. 2A to 2C, to arrive at the secured position. FIG. 2A shows the slider 214 in the released position, with the spring 232 at its furthest or most relaxed extent. FIG. 2B shows the connector 210 inserted into the receptacle 204 past the point of engagement 218, where the connector 210 has pressed the cam mechanism 234 inwards to compress the spring 232. The connector 210 withdraws a small amount out of contact with the cam mechanism 234, which locks in place with the cam stop 236, as shown in FIG. 2C, which shows the secured position. As can be seen in FIG. 2C, the protrusion 212 on the clip 208 of the connector 210 enters a latched position with the catch 206 on the body 202 at the point of engagement 218. The connector 210 is thus secured in the receptable 204 and the bias mechanism 230 stores mechanical energy for ejection of the connector 210 at a later time.

[0035] To remove the connector 210 from the receptacle 204, as shown in FIG. 2D, the connector 210 is pressed into the receptable 204 to over-insert the connector 210 past the point of engagement 218 of the catch 206. This causes the connector 210 to press the cam mechanism 234, which unlocks from the cam stop 236. The spring 232 is now released to provide the ejecting force. In the same action, the clip 208 of the connector 210 is pressed against the leg 216 of the slider 214. Specifically, the clip 208 is pressed against the contact surface 220 of the slider 214, which bends the clip 208 and moves the protrusion 212 on the clip 208 out of alignment with the catch 206 on the body 202. In effect, the slider 214 bends the clip 208 into an unlatched position, similar to what would happen if a user pressed the clip 208 with their finger from outside the receptacle 204 but without needing the user to press the clip 208. Then, as shown in FIG. 2E, the spring 232 applies the ejecting force to the slider 214, which pushes the connector 210 by the clip 208 out of the receptacle 204. The slider 214 maintains contact with the clip 208, so as to keep pressing the clip 208 down to keep the protrusion 212 away from the catch 206 on the body 202, thereby allowing the connector 210 to withdraw from the receptacle 204. In addition, since the slider 214 is coupled to the cam mechanism 234 some of the ejecting force may also be transmitted to the connector 210 by the cam mechanism 234. The connector 210 may thus be freely removed from the receptacle, as shown in FIG. 2A.

[0036] Hence, the bias mechanism 230 provides a push-to-secure and push- to-release (or push-push) action that latches the connector 210 in response to a first over-insertion of the connector 210 into the receptacle 204 (FIG. 2B) and unlatches the connector 210 in response to a subsequent, second overinsertion (FIG. 2D) of the connector 210 into the receptacle 204.

[0037] FIG. 3 shows an example cam mechanism and cam stop that may be used with the example devices discussed elsewhere herein. For example, the cam mechanism may be used as the cam mechanism 234 of the device 200 and the cam stop may be used as the cam stop 236 of the device 200.

[0038] The cam mechanism 300 includes a cam body 302 and a plunger 304. The cam stop is depicted at 306. The cam body 302, plunger 304, and cam stop 306 are generally cylindrical in shape. The cam stop 306 is hollow and the plunger 304 slides within the cam stop 306, along arrow D. The plunger 304 is also captured within the cam stop 306, so that the plunger’s sliding is limited and it cannot disengage from the cam stop 306. The plunger 304 is constrained against rotation by the cam stop 306 with, for example, a grove and ridge structure (not shown). The cam body 302 engages with both the cam stop 306 and the plunger 304 and can slide in the direction of the plunger 304 and rotate, in the direction of arrow R, with respect to the cam stop 306.

[0039] The cam stop 306 includes long grooves 310 and short grooves 312 at alternating points around its circumference. The cam stop 306 further includes cam surfaces 314 between the long grooves 310 and the short grooves 312. The grooves 310, 312 are shaped to receive raised ridges 318 on the cam body 302.

[0040] The raised ridges 318 on the cam body 302 include cam surfaces 320 that abut with the cam surfaces 314 of the cam stop 306 to urge the cam body 302 to rotate in the direction of arrow R to alternately index the raised ridges 318 into the long grooves 310 and the short grooves 312. When the raised ridges 318 are located in the long grooves 310, the cam body 302 is positioned (rightward, in the figure) in the cam stop 306 to extend the plunger 304 (rightward) from the cam stop 306. When the raised ridges 318 are located in the short grooves 312, the cam body 302 is positioned (leftward) further out of the cam stop 306 to retract the plunger 304 (leftward) into the cam stop 306. In other words, when a point 322 of the cam surface 320 of the cam body 302 is located at a point 324 in the long groove 310 of the cam stop 306, the cam body 302 pushes the plunger 304 rightward to an extended position that urges a connector out of a receptable. Conversely, when the point 322 of the cam surface 320 of the cam body 302 is located at a point 326 in the short groove 312 o the cam stop 306, the cam body 302 pushes allows the plunger 304 to move leftward to a retracted position that provides space for the connector in the receptable.

[0041 ] The plunger 304 includes teeth 330 at its circumference facing the cam body 302. The teeth 330 engage with the cam surfaces 320 of the cam body 302 to urge the cam body 302 to rotate in the direction R, so as to alternately index the raised ridges 318 of the cam body 302 into the long grooves 310 and the short grooves 312 of the cam stop 306. The cam surfaces 320 of the cam body 302, teeth 330 of the plunger 304, and cam surfaces 314 of the cam stop 306 are urged into contact by a spring force F provided by a spring, such as the spring 232 discussed above, and the limit in linear movement of the plunger 304 enforced by the cam stop 306. The plunger 304 includes a contact surface 332 to contact by connector.

[0042] Flat surfaces 334 on the raised ridges 318 of the cam body 302 and flat surfaces 336 bounding the grooves 310, 312 in the cam stop 306 hold the cam body against rotation 302, as urged by the teeth 330 of the plunger 304, until the raised ridges 318 move (leftward) clear the respective grooves 310, 312.

[0043] In operation, with the slider 214 starting in the released position, the cam body 302 occupies the long grooves 310 of the cam stop 306 and thus the cam body 302 is urged rightward under force F of the spring and pushes the plunger 304 rightward to an extended position. The contact surface 332 of the plunger 304 is then pushed by a connector inserted into the receptable. The plunger 304 moves the cam body 302 against the spring force F. The teeth 330 of the plunger 304 in contact with the cam surfaces 320 of the cam body 302 urge the cam body 302 to rotate. The cam body 302 rotates when the raised ridges 318 exit the long grooves 310 of the cam stop 306, which is about at the position of over-insertion of the connector. The connector is allowed to withdraw slightly and the cam surfaces 320 of the cam body 302 follow the cam surfaces 314 of the cam stop 306, rotating the cam body 302, until the cam body 302 rests in the short grooves 312 of the cam stop 306. The connector is thus inserted and the slider 214 is in the secured position.

[0044] To release the connector, the connector is over-pushed into the receptacle against the contact surface 332 of the plunger 304. The plunger 304 moves the cam body 302 against the spring force F. The teeth 330 of the plunger 304 in contact with the cam surfaces 320 of the cam body 302 urge the cam body 302 to rotate. The cam body 302 rotates when the raised ridges 318 exit the short grooves 312 of the cam stop 306, which again is about at the position of over-insertion of the connector. The connector is allowed to withdraw and the cam surfaces 320 of the cam body 302 follow the cam surfaces 314 of the cam stop 306, rotating the cam body 302, while the cam body 302 and plunger 304 push the connector out of the receptacle, until the cam body 302 reaches the end of the long grooves 310 of the cam stop 306. The connector is thus removed the slider 214 is in the released position.

[0045] FIG. 4 shows an example device 400 with an alternative spring. The description of the device 200 may be referenced for details not repeated here, with like terminology and like reference numerals denoting like components. A cantilevered spring 402 may have one end 404 affixed to the body 202 and another end 406 free to abut the base portion 244 of the slider 214, so as to provide an ejecting force. In other examples, the cantilevered spring 402 may be affixed to the base portion 244 of the slider 214 and free to abut the body 202.

[0046] FIG. 5 shows an example device 500 with another alternative spring. The description of the device 200 may be referenced for details not repeated here, with like terminology and like reference numerals denoting like components. A resilient compressible member 502, such as a solid elastomeric member or hollow elastomeric member may be provided between the body 202 and the base portion 244 of the slider 214, so as to provide an ejecting force.

[0047] In view of the above, it should be apparent that a receptacle includes a slider to unlatch a connector from the receptacle in response to over-pushing the connector into the receptacle. This may allow for tight receptacle layouts that omit extra space for a user’s hand to manually depress the latch from outside the receptacle. Further, the connector is not modified, so that in many cases only receptacles are replaced or modified to implement this functionality.

[0048] It should be recognized that features and aspects of the various examples provided above can be combined into further examples that also fall within the scope of the present disclosure. In addition, the figures are not to scale and may have size and shape exaggerated for illustrative purposes.
