Abstract

A small, low-profile plug connector for use with electronic devices provides a latching member with a pair of hooks that engage mating holes in a guide frame, and which can be easily delatched 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 simple ramp and lobe mechanism in the plug connector. The ramp and lobe mechanism converts horizontal movement of a pull tab-like actuator into vertical movement of a latching member such that the hooks are lifted upward and disengaged from the guide frame or housing.

Claims

1. A plug connector comprising:

a plug connector body having a front portion and a rear portion, the front portion including a first surface and said front portion being sized to fit within a mating receptacle connector, the rear portion having a second surface disposed at a level on the plug connector body that is above the first surface, the connector body further including a ramped surface disposed on said rear portion proximate to said front portion, the ramped surface being inclined at an angle relative to said front portion first surface and extending away from said front portion, said ramped surface having a length that extends at least part way between the level of said front portion first surface and said rear portion second surface;

a latching member including a first end attached to the rear portion and a second end that is cantilevered from the first end thereof, the latching member second end extending over a portion of said rear portion second surface and over a portion of said front portion first surface; and

,

an actuator having a first end that protrudes beyond said rear portion and a second end that extends toward said front portion, the actuator second end being interposed between said latching member and said ramped surface, whereby movement of said actuator second end along said ramped surface rearwardly away from said front portion causes said latching member second end to be raised above said front portion first side surface.

2. The connector of claim 1, wherein said actuator second end further includes a lobe which rides against said ramped surface and slides upwardly toward said rear portion second surface as said actuator is pulled in a direction away from said front portion, the upward movement of said lobe causing it to press against said latching member and lift said latching member first end away from said front portion first surface.

3. The plug connector of claim 2, wherein said lobe has a cylindrical configuration which is oriented transverse to said ramped surface.

4. The plug connector of claim 1, wherein said latching member first end includes at least one engagement hook that is capable of extending into an opening in a surface of a opposing mating structure, when said plug connector is inserted into said opposing mating structure.

5. The plug connector of claim 4, wherein said latching member is partially biased against said actuator and said engagement hook thereof is biased toward said front portion first surface.

6. The plug connector of claim 1, wherein said front portion first surface is a top surface thereof and said second portion side surface is a top surface thereof.

7. The plug connector of claim 1, wherein said rear portion includes a channel and said actuator and latching member are disposed in the channel, said channel terminating at one end thereof in a ramped surface that extends toward said front portion.

8. The plug connector of claim 7, wherein said channel is T-shaped including a longitudinal body portion and two wing portions extending transversely to the channel body portion, and said latching member is T-shaped, said latching member including a longitudinal body portion received in said channel body portion and two wing portions, which are received in said channel wing portions, said actuator extending within said channel body portion.

9. The plug connector of claim 8, wherein latching member body portion is offset upwardly with respect to said latching member wing portions to define an intervening space within said channel body portion, said actuator being received within said intervening space.

10. The plug connector of claim 9, wherein said latching member is attached to said connector body rear portion at said latching member wing portions, and said latching member second end is offset downwardly with respect to said latching member body portion.

11. The plug connector of claim 8, wherein said actuator is capable of longitudinal movement in said intervening space and said connector includes means for limiting the longitudinal movement of said actuator on said connector body rear portion.

12. The plug connector of claim 11, wherein said actuator movement limiting means includes a stop member disposed in said channel and said actuator includes an opening formed in said actuator that receives the stop member therein.

13. The plug connector of claim 1, wherein said actuator first end includes a pull tab.

14. The plug connector of claim 13, wherein said pull tab includes a finger opening that may be grasped by a user.

15. 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 a cable containing electrical wires to enter into said connector body, said connector body further including distinct first and second portions. the first portion of the connector body being sized to fit within a receptacle portion of the opposing connector and the second portion of said connector body being larger than said connector body first portion, said connector body second portion including a channel disposed in a top surface thereof and extending in a longitudinal direction between said connector body first portion and said connector body rear end, the channel including an inclined cam surface proximate said connector body first portion;

a latching member having opposing first and second ends interconnected by a longitudinal body portion, the first end including a free end defining an engagement portion that extends over said connector body first portion, the engagement portion including at least one engagement hook for engaging said opposing connector, the latching member second end being attached to the connector body second portion top surface, latching member second end to said connector body portion top surface the attachment permitting said latching member to move between first and second operative positions; and

,

an actuator for moving said engagement member engagement portion between said first and second operative positions, the actuator having opposing first and second ends, the actuator first end being interposed between said latching member and said connector body member second portion, said actuator second end extending rearwardly of said connector second portion and including an enlarged section for grasping by a user, said actuator first end including a cam end disposed proximate to said connector body second portion cam surface and between said latching member body portion and said connector body second portion, whereby movement of said actuator by a user in a first direction moves said cam end along said connector body second portion inclined cam surface, and said cam end contacts said latching member, thereby raising said latching member engagement portion in said first direction.

16. The connector of claim 15, wherein said actuator second end enlarged section includes a pull tab with an opening for receiving the finger of a user.

17. The connector of claim 15, wherein said connector body second portion channel receives both said actuator and said engagement member therein.

18. The connector of claim 17, wherein said latching member is T-shaped and said latching member second end includes a pair of wing portions extending transversely outwardly from said latching member body portion, said latching member second end being attached to said connector body second portion at the latching member wing portions.

19. The connector of claim 18, wherein said latching member wing portions are vertically offset form said latching member body portion to define an intervening space between said latching member body portion and a base of said channel.
