Abstract

One of a pair of electrical connectors has a resilient cantilevered locking arm 15 which has a finger plate 19 for release thereof. The finger plate is undercut on one side to accommodate a travel stop constituted by an upstanding sidewall 17. The other sidewall 16 extends to at least the upper surface of the arm 15 thereby resisting accidental release thereof. The arrangement permits the width of the connector to be reduced whilst giving better access to the finger plate 19.

Claims

1. An electrical connector comprising:

a housing and a cantilever locking arm secured to said housing, said housing including first and second sidewalls which define a width of the connector and a transverse wall interconnecting said sidewalls, each sidewall extending beyond said transverse wall to define an outer edge, the outer edge of the second sidewall being spaced farther from the transverse wall than the outer edge of the first sidewall, said locking arm being movable towards said transverse wall of the housing against a resilient bias for locking engagement with a mating connector, said locking arm having an inner side facing said transverse wall, said locking arm being positioned generally between said sidewalls, said inner side of said locking arm being generally between said transverse wall and said outer edges when not depressed, and said locking arm further including a portion which at least partially overlaps the outer edge of said first sidewall for abutting said outer edge of said first sidewall when said locking arm is depressed, whereby the width of the connector is reduced.

2. A connector in accordance with claim 1 wherein said locking arm includes an outer side opposite said inner side, and said outer edge of said second sidewall is spaced away from said transverse wall at least as far as said outer side of said locking arm when said locking arm is not depressed.

3. A connector in accordance with claim 1 wherein said locking arm includes a free end, and said portion that at least partially overlaps said outer edge of said first sidewall is defined by a laterally projecting plate portion positioned at only the free end of the locking arm.

4. A connector in accordance with claim 1 wherein said housing and said locking arm are formed as a one-piece plastic member.
