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).
