Abstract

Electrical connectors having latches for holding the connectors in mated condition employ relatively long latch arms with a point of flexure near a rear end of the connector. The latches extend into locating posts positioned forwardly of the mating face of the connector. If multiple latch arms are used, they are interconnected by a commonly actuated cross bar. Latch arms may be formed by integrally molding the arms with covers of the connectors. Effective latching properties and a long life are achieved with such latch structures. Manufacturing costs may be reduced by integrally molding latches with covers of the connector.

Claims

1. A connector for establishing an electrical connection with a mating connector comprising:

a terminal housing having a front face for mating with the mating connector and a rear portion in opposed relation to the front face;

a plurality of contact terminals disposed along said front face;

a projection extending forwardly from said front face for engaging guidance structure in the mating connector;

at least two biased latch arms joined by a cross member insuring common and simultaneous activation of both arms, each arm having a distal portion with a latch pawl disposed in said projection, an intermediate portion extending along said housing and a proximal portion forming a fulcrum for the latch arm disposed at said rear portion;

a cover overlying said housing and an actuator means associated with the latch arm for moving the latch pawl to a disengaging position and wherein the fulcrum of the latch arm is secured on the cover.

2. The connector as in claim 1, wherein the latch arm is integral with the cover.

3. The connector as in claim 2, wherein the cover and the latch arm integrally molded.

4. The connector as in claim 1, wherein said projection comprises a first projection and said front face includes a second forwardly extending projection laterally spaced from the first projection and a second latch arm having a distal portion with a latch pawl disposed in the second projection, an intermediate portion extending along the housing and a proximal portion forming fulcrum for the second latch arm secured on the cover;

and

an actuating means secured to the first and second latch arms for moving the latch pawls to a disengaging position.

5. The connector as in claim 4, wherein the cover is formed of a moldable material and the first and second latch arms are integrally molded with the cover.

6. The connector as in claim 5, wherein the actuating means is integrally molded with the first and second latch arms and the cover.

7. A connector for establishing an electrical connection with a mating connector comprising:

a terminal housing having a front face for mating with the mating connector and a rear portion in opposed relation to the front face;

a plurality of contact terminals disposed along said front face;

at least two biased latch arms joined by a cross member insuring common and simultaneous activation of both arms, each arm having a distal portion with a latch pawl positioned to engage the mating connector and a proximal portion forming a fulcrum for the latch arm; and

a cover overlying said housing, wherein the fulcrum of the latch arm is secured on the cover.

8. The connector as in claim 7, wherein the latch arm is integral with the cover.

9. The connector as in claim 8, wherein the cover and the latch arm are integrally molded.

10. The connector as in claim 7 and further comprising a second latch arm having a distal portion with a latch pawl positioned to engage the mating connector along a proximal portion forming fulcrum for the second latch arm secured on the cover;

and

an actuating means secured to the first and second latch arms for moving the latch pawls to a disengaging position.

11. The connector as in claim 10, wherein the cover is formed of a moldable material and the first and second latch arms are integrally molded with the cover.

12. The connector as in claim 11, wherein the actuating means is integrally molded with the first and second latch arms and the cover.
