Low profile latching connector
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 disengaged from the guide frame or opposing connector or housing. The connector includes an elongated actuator interposed between the connector housing and latching member and the actuator terminates in a cylindrical cam member that is captured in a recess on the connector housing such that rearward movement of the actuator imparts a raising action to the latching member.
1. A connector, comprising:
a connector housing having a front portion and a rear portion, the front portion being sized to fit within a mating receptacle and having a first surface, the rear portion having a second surface disposed on the connector housing, the first and second surfaces being disposed in different planes;
a latching member including a first end attached to the rear portion second surface, a second end at least partially extending over the front portion first surface, and a cam surface disposed between the latching member first and second ends;
an actuator at least partially interposed between the latching member and the connector housing and extending lengthwise along the connector housing, the actuator including a cam member disposed at a first end thereof, the cam member being a roll pin formed separately from the actuator, the cam member being captured in a recess disposed in the connector housing and being movable between first and second operative positions wherein the actuator comprises an elongated flexible strip folded over the cam member and onto itself so as to secure the cam member, the cam surface being at least partially disposed in the recess such that pulling on the actuator in a first direction causes the cam member to move from the first operative position to the second operative position, whereby the cam member contacts the cam surface and lifts the latching member upwardly away from the first surface.
2. The connector of claim 1 , wherein the cam surface extends at an angle such that rearward movement of the actuator and roll pin causes the free end to lift upwardly, and the cam surface exerts a return force on the roll pin.
3. The connector of claim 1 , wherein the recess and the cam member are wider than the cam surface.
4. The connector of claim 1 , wherein the cam surface extends in a second direction, angularly offset from the first direction to remain in contact with the cam member when pulled.
5. The connector of claim 1 , wherein the cam surface extends downwardly and rearwardly from the latching member, and terminates in a free end that extends into the connector housing recess.
6. The connector of claim 5 , wherein the actuator includes a slot disposed therein proximate the recess and the cam surface extends at least partially through the slot.
7. The connector of claim 6 , wherein the cam surface has a width less than a corresponding width of the latching member.
8. The connector of claim 1 , wherein the latching member has a T-shaped configuration with an elongated base and two wings, the base extending along the rear portion over the recess.
9. The connector of claim 8 , wherein the cam surface is disposed on the base and extends toward the wings.
10. The connector of claim 8 , wherein the rear portion includes a lengthwise channel and the actuator is disposed in the channel and the cam member is disposed in the recess.
