Abstract

An electrical connector includes a connector housing and 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 that includes an actuator and a latch body. The actuator has an actuator portion and at least one arm extending from the actuator portion. The arm includes a proximal end connected to the actuator portion, an opposed distal end, and an intermediate portion. The intermediate portion is retained by the connector housing at a location below the distal end. The latch body is connected to the connector housing so as to rotate about a pivot axis. The latch body includes a latch member at one side of the pivot axis, and a spring disposed at a second opposite side of the pivot axis. The spring provides a spring force that biases the latch member toward a latched position. The distal end of the at least one arm is attached to the latch body at the second opposite side of the pivot axis, such that an actuation force applied to the actuator causes the latch body to pivot against the spring force so as to urge the latch member to an unlatched position.

Claims

1. An electrical connector comprising:

a connector housing, and 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; and

a latch assembly including;

an actuator having an actuator portion and at least one arm that defines a proximal end and a distal end, wherein the proximal end extends from the actuator portion, and the at least one arm is retained by the connector housing at a location that is inwardly recessed with respect to the distal end;

a latch body pivotally connected to the connector housing at a pivot location, the latch body attached to the distal end of the at least one arm at a first side of the pivot location, and the latch body including a latch member disposed at a second side of the pivot location opposite the first side, wherein movement of the at least one arm causes the latch body to rotate about the pivot location, thereby actuating the latch member from a latched position to an unlatched position.

2. The electrical connector as recited in claim 1, further comprising a spring that provides a spring force that biases the latch member toward the latched position.

3. The electrical connector as recited in claim 2, wherein the spring is integral with the latch body and abuts the housing so as to provide the spring force.

4. The electrical connector as recited in claim 1, wherein the connector housing define a seat surface, in the latched position the latch member is biased toward the seat surface, and in the unlatched position the latch member is biased away from the seat surface against the spring force.

5. The electrical connector as recited in claim 4, wherein the spring member extends proximally from the first side of the pivot location against the connector housing so as to bias the latch member against the seat surface.

6. The electrical connector as recited in claim 1, further comprising a mounting interface at a rear end of the connector housing, wherein the actuator portion extends rearward with respect to the mounting interface, and an actuation force applied to the actuator along a direction away from the connector housing causes the movement of the at least one arm.

7. The electrical connector as recited in claim 6, wherein the actuator portion further comprises a pair of grip tabs that are spaced and define respective inner surfaces configured to face a cable to which the electrical connector is mounted.

8. The electrical connector as recited in claim 7, wherein the grip tabs are laterally spaced.

9. The electrical connector as recited in claim 8, wherein the grip tabs are substantially planar.

10. The electrical connector as recited in claim 9, wherein the grip tabs are curved.

11. The electrical connector as recited in claim 7, further comprising a cable grip that extends from each of the grip tabs so as to at least partially wrap around the cable.

12. The electrical connector as recited in claim 11, wherein the cable grips are spaced from each other such that the actuator is discontinuous about the cable.

13. The electrical connector as recited in claim 12, further comprising a junction connected between the grip tabs and the at least one arm, and a reinforcing member that extends about the junction and the cable grip.

14. The electrical connector as recited in claim 7, wherein the electrical connector is configured to electrically connect to a pair of cables at the mounting interface, such that the pair of cables extends between the opposed grip tabs.

15. The electrical connector as recited in claim 14, further comprising a flexible junction connected between the grip tabs, wherein the junction is configured to slidably retain each of the pair of cables.

16. The electrical connector as recited in claim 15, wherein the grip tabs extend rearward with respect to the junction.

17. The electrical connector as recited in claim 16, wherein the arms are connected between the junction and the grip tabs, respectively.

18. The electrical connector as recited in claim 7, wherein the grip tabs are opposite each other such that the cable is disposed between the grip tabs.

19. The electrical connector as recited in claim 6, wherein the actuator portion further comprises a grip portion that is substantially tubular so as to be substantially continuous about a cable to which the electrical connector is mounted.

20. The electrical connector as recited in claim 19, wherein the grip portion comprises a pair of grip members that are spaced along a length of the cable.

21. The electrical connector as recited in claim 20, further comprising a plurality of circumferentially spaced panels that are connected between each of the pair of grip members.

22. The electrical connector as recited in claim 1, wherein the pivot location is a pivot axis that is fixed with respect to the connector housing as the a latch body rotates about the pivot axis so as to actuate the latch member from the latched position to the unlatched position.

23. An electrical connector comprising:

a connector housing that defines an upper surface and a brace that is inwardly offset with respect to the surface

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; and

a latch assembly including;

an actuator having an actuator portion and at least one arm that defines a proximal end and a distal end, wherein the proximal end extends from the actuator portion, and the at least one arm is retained by the connector housing and supported at a location that is inwardly recessed with respect to the distal end;

a latch body pivotally connected to the connector housing at a pivot location, the latch body attached to the distal end of the at least one arm at a first side of the pivot location, and the latch body including a latch member disposed at a second side of the pivot location opposite the first side, wherein movement of the at least one arm causes the latch body to rotate about the pivot location, thereby actuating the latch member from a latched position to an unlatched position,

wherein the upper surface supports the at least one arm, such that the at least one arm extends from the upper surface to a location below the brace.

24. The electrical connector as recited in claim 23, wherein the connector housing further defines a tapered ramp surface having a proximal end adjacent the upper surface, the ramp surface extending from its proximal end so as to define a distal surface that is spaced below the proximal end of the ramp surface.

25. The electrical connector as recited in claim 24, wherein the distal surface of the ramp surface is spaced below the brace.

26. The electrical connector as recited in claim 24, wherein the at least one arm extends from the upper surface to a location below the brace.
