Abstract

An electrical connector can includes a connector housing that includes a housing body and further includes at least one fulcrum supported by the housing body. The electrical connector further includes at least one electrical contact supported by the connector housing, the at least one electrical contact configured to mate with a complementary electrical contact of a complementary electrical connector. The electrical connector further includes a latch assembly. The latch assembly can include an actuator and a latch. The actuator can have an actuator portion, an attachment portion, and at least one arm that extends between the actuator portion and the attachment portion. The latch can have a latch body that defines an attachment portion that is configured to be attached to the attachment portion of the actuator, such that movement of the actuator in a predetermined direction causes the pivot member to ride along the fulcrum, thereby pivoting the latch from a latched position to an unlatched position.

3. The electrical connector as recited in claim 2, wherein the pivot member defines a pivot axis, and the latch body is configured to pivot about the pivot axis in response to the movement of the actuator, such that the pivot axis revolves about the central axis of the fulcrum.

4. The electrical connector as recited in claim 1, wherein when the latch body is in the latched position, the latch member is disposed closer to the housing body than when the latch body is in the unlatched position.

5. The electrical connector as recited in claim 1, wherein the latch further comprises a spring that extends from the latch body, the spring providing a spring force that biases the latch member toward the latched position.

6. The electrical connector as recited in claim 5, wherein the spring resiliently flexes against the connector housing as the latch member pivots from the latched position to the unlatched position.

7. The electrical connector as recited in claim 6, wherein the spring extends from the latch body along a direction that is substantially parallel to the predetermined direction.

8. The electrical connector as recited in claim 6, wherein the spring is a first spring, the latch further comprises a second spring that extends from the latch body along a direction opposite that of the first spring.

9. The electrical connector as recited in claim 5, wherein the spring is monolithic with the latch body.

10. The electrical connector as recited in claim 1, wherein:

the second attachment portion comprises first and second side walls that are spaced apart along a lateral direction that is substantially perpendicular to the predetermined direction so as to define a slot between the first and second side walls and a first distance that extends along the lateral direction through the slot from the first side wall to the second side wall; and

the first attachment portion comprises

     1) a neck that extends along the lateral direction a second distance that is no greater than the first distance, and

     2) a cross-bar that extends from the neck so as to define a third distance along the lateral direction that is greater than the first distance, such that the neck is configured to extend through the slot such that the cross-bar bears against at least one of the first and second arms during the movement of the actuator.

11. The electrical connector as recited in claim 10, wherein the second attachment portion further comprises an end wall connected between the first and second side walls, such that the cross-bar further bears against the end wall during the movement of the actuator.

12. The electrical connector as recited in claim 1, further comprising at least one support block that extends from the housing body, the support block defining a recess that is sized to receive the pivot member at a location adjacent the fulcrum.

13. The electrical connector as recited in claim 12, wherein the pivot member is adjacent the fulcrum along the predetermined direction when the pivot member is disposed in the recess.

14. The electrical connector as recited in claim 13, wherein the pivot member abuts the fulcrum both when the latch is in the latched position and when the latch is in the unlatched position.

15. The electrical connector as recited in claim 14, wherein a first location of the pivot member abuts the fulcrum when the latch is in the latched position, and a second location of the pivot member that is spaced from the first location abuts the fulcrum when the latch is in the unlatched position.

16. The electrical connector as recited in claim 1, wherein the latch comprises a pair of attachment portions that are spaced from each other along the predetermined direction, each of the attachment portions configured to attach to the first attachment portion.

17. The electrical connector as recited in claim 10, wherein the latch comprises a pair of attachment portions that are spaced from each other along the predetermined direction, a select one attachment portion of the pair of attachment portions defines the slot and the other attachment portion of the pair of attachment portions defines a second slot.

18. The electrical connector as recited in claim 17, wherein the neck extends through the second slot in a first direction and extends through the slot in a second direction opposite the first direction such that the cross-bar bears against the first and second side walls of the select one attachment member.

19. The electrical connector as recited in claim 17, wherein the pivot member is disposed closer to the select one attachment portion than the other attachment portion.
