ABSTRACT:
An electronic key assembly (10) comprising an insulating plug body (11) having a front mating end (17) for receipt in a jack and a rearwardly spaced, chip carrier receiving cavity (19). A series of contacts (12) having first contact portions (34) are mounted in body recesses (32) at the mating end for engagement with spring contacts of a complementary jack and second spring contact portions (36) which extend into the cavity (19) are for engagement with respective leads of a chip carrier (15) received therein. Releasable latch arms (41) extend rearwardly from the mating end (17) and a sleeve-form shield (12) moulded in the fingerpiece (14) is received on the body (11) to surround a rear end and the chip carrier (15). Anti-overstress arms (64) extending from the fingerpiece (14) hook over the latch arms (41) to prevent excessive movement of the latch arms (41) away from the body (11). The shield (192) includes a window (194) having a rim (195) surrounding the first contact portions (180) and the fingerpiece (210) includes a tongue (213) which extends forwardly within the shield (192) to a location adjacent the first contact portions partly to close the window (194).
