Abstract

A low-profile connector for use with electronic devices provides a cantilevered latching arm with a pair of engagement hooks that engage mating holes in a guide frame, and which can be easily unlatched from the guide frame or opposing connector or housing. The hooks lock the plug connector into engagement with the frame or housing, but are readily released by way of a rotating cam lobe mechanism. The lobe mechanism converts horizontal pulling movement of an actuator into vertical, lifting movement of the latching arm such that the hooks are lifted upward and disengaged from the guide frame or housing.

First claim

What is claimed is:

1 . A plug connector comprising:
a plug connector housing, the housing having a front portion and a rear portion, the front portion being sized to fit within a mating receptacle connector, the rear portion being configured to hold at least one cable in place within the housing, the housing including a longitudinal channel disposed thereon; a latching member, the latching member having a first end attached to the rear portion and a second end cantilevered from the first end so that the second end extends forwardly over a portion of the front portion, the latching member including at least one engagement hook for engaging the mating receptacle connector; and an actuator for raising and lowering the second end, the actuator including an elongated body portion disposed in the channel, the body portion including a grasping end and an actuating end, the actuating end including an enlarged end portion captured within a portion of the channel, whereby exerting a pulling force on the grasping end causes the end portion to contact the channel and move upwardly, thereby raising the second end above the front portion.

2 . The connector of claim 1 , wherein the end portion includes a leg portion extending at least partially rearwardly under the body portion.

3 . The plug connector of claim 1 , wherein the channel includes a recess disposed therein, the recess extending transversely within the channel, the end portion being captured therewithin, the recess including a shoulder portion, the shoulder portion defining a stop surface extending transversely with respect to the actuator.

4 . The plug connector of claim 1 , wherein the stop surface opposes an end of end portion.

5 . The plug connector of claim 1 , wherein the end portion rotates toward the grasping end when a pulling force is exhibited on the actuator.

6 . The plug connector of claim 2 , wherein the channel has a flat bottom surface that defines a substantially horizontal plane.

7 . The plug connector of claim 2 , wherein the actuator further includes a re-entrant portion interposed between the body portion and the end portion.

8 . The plug connector of claim 7 , wherein the end and leg portions each have a length not less than a height of one of the engagement hooks.

9 . The plug connector of claim 2 , wherein the end portion rotates around a point disposed on the body portion between ends of the end portion.

10 . A connector, comprising:
a connector body having a mating end for mating with an opposing connector and a rear end disposed opposite the mating end, the rear end defining an entry location for at least one cable, each cable containing electrical wires to enter into the connector body, the connector body including a channel disposed thereon, the channel including a transverse recess disposed therein; a latching member having opposing first and second ends, the latching member second end engaging the body to fix the latching member thereto, the latching member including a latching arm extending away from the latching member second end in a cantilevered fashion and terminating in the latching member first end, the latching member first end defining an engagement portion that extends forwardly of the channel, the engagement portion including at least one engagement hook for engaging the opposing connector; and an actuator for moving the engagement portion between first and second operative positions, the actuator having opposing first and second ends, the actuator first end being disposed in the transverse recess and interposed between the latching member and the body, the actuator second end extending rearwardly of the mating end and including an enlarged section for grasping, the actuator first end including a cam end, whereby movement of the actuator in a first direction causes the cam end to contact the body and move upwardly into lifting contact with the latching member proximate to the engagement portion.

11 . The connector of claim 10 , wherein the recess includes a stop surface disposed along a rear end thereof.

12 . The connector of claim 10 , wherein the latching member further includes a collar that encircles the rear end.

13 . The connector of claim 10 , wherein the cam end includes an enlarged lobe with a leg portion extending rearwardly therefrom and underneath the body portion, the leg portion being separated from the body portion by an intervening re-entrant portion.

14 . The connector of claim 13 , wherein the cam end rotates upwardly toward a direction of a pulling force exerted on the actuator second end.

15 . The connector of claim 13 , wherein the cam end rotates about an axis of rotation disposed on the body portion reawardly of the cam end.

16 . The connector of claim 13 , wherein the cam end enlarged lobe and leg portion have a length not less than a depth of the engagement hook.

17 . The connector of claim 10 , further including an electromagnetic interference gasket disposed on the body forwardly of the recess, the gasket including a plurality of spring fingers extending rearwardly past the engagement hook.

18 . A cable connector with mating with an opposing connector, comprising:
a connector housing having a mating end for mating to the opposing connector and a rear end, the rear end having an opening disposed therein for receiving at least one electrical wire therein, the rear end including a longitudinal channel disposed thereon; a latch member disposed on the rear end, the latch member including a body portion fixed to the rear end, the body portion including an elongated latching arm that extends longitudinally along the housing, in a cantilevered fashion from the body portion toward the mating end, such that the latching arm is free to deflect in a vertical direction; and an actuator for vertically deflecting the latching arm into and out of engagement with an opposing connector, the actuator including an enlarged end and a pulling end, the enlarged end being captured in a recess disposed in the channel proximate the mating end, the enlarged end being further interposed between the latching arm and the connector housing, whereby when the actuator is pulled, the enlarged end contacts a stop surface of the recess and rotates into contact with the latching arm to vertically deflect the latching arm.

19 . The cable connector of claim 18 , wherein the enlarged end includes a contact portion that extends above a body portion of the actuator and a leg portion extending rearwardly underneath the body portion, the enlarged end having a length less than a. corresponding length of the recess.

20 . The cable connector of claim 19 , wherein the enlarged end contacts the stop surface when the actuator is pulled, causing the enlarged end to rotate in the direction of pulling and upwardly into contact with the latching arm.
