Abstract
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).

Claim 1
Independent Claim
199 words
An electronic key assembly comprising an insulating plug body moulded from plastics material having a front, mating end for receipt in a jack and a rear end and formed with a chip carrier receiving cavity spaced rearwardly from the mating end; a row of contact receiving recesses extending rearwardly from the mating end along a side of the body towards the cavity; a series of contacts having first contact portions mounted in the recesses for engagement with spring contacts of a complementary jack and second spring contact portions extending into the cavity for engagement with respective leads of a chip carrier received in the cavity; releasable latch arm means extending rearwardly from the mating end; and, a sleeve-form shield receivable on the body surrounding the rear end and extending forwardly over the cavity to the mating end thereby completely to enclose and shield the chip carrier in the cavity, the shield including a forwardly extending flap formed with a window, a rim of which window is deformable to extend along the side of the body and along the mating end surrounding the first contact portions of the series of contacts so that they are in registration with the window.
Claim 2
Dependent Claim
199 words
An electronic key assembly comprising an insulating plug body moulded from plastics material having a front, mating end for receipt in a jack and a rear end and formed with a chip carrier receiving cavity spaced rearwardly from the mating end; a row of contact receiving recesses extending rearwardly from the mating end along a side of the body towards the cavity; a series of contacts having first contact portions mounted in the recesses for engagement with spring contacts of a complementary jack and second spring contact portions extending into the cavity for engagement with respective leads of a chip carrier received in the cavity; releasable latch arm means extending rearwardly from the mating end; and, a sleeve-form shield receivable on the body surrounding the rear end and extending forwardly over the cavity to the mating end thereby completely to enclose and shield the chip carrier in the cavity, the shield including a forwardly extending flap formed with a window, a rim of which window is deformable to extend along the side of the body and along the mating end surrounding the first contact portions of the series of contacts so that they are in registration with the window.
Claim 3
Dependent Claim
79 words
An electronic key assembly according to claim 1 in which a wall of the sleeve defining the window is spaced apart rearwardly of the first contact portions, a rear end of the shield being anchorable in a fingerpiece which includes a tongue which extends forwardly through the sleeve over the cavity to a location adjacent the recesses receiving the first contact portions to bridge the space between the sleeve wall and the recesses thereby completely to close the cavity.
Claim 4
Dependent Claim
197 words
An electronic key assembly comprising an insulating plug body moulded from plastics material having a front, mating end for receipt in a jack and a rear end and formed with a chip carrier receiving cavity spaced rearwardly from the mating end; a row of contact receiving recesses extending rearwardly from the mating end along a side of the body towards the cavity; a series of contacts having first contact portions mounted in the recesses for engagement with spring contacts of a complementary jack and second spring contact portions extending into the cavity for engagement with respective leads of a chip carrier received in the cavity; releasable latch arm means extending rearwardly from the mating end; and, a sleeve-form shield receivable on the body surrounding the rear end and extending forwardly over the cavity to the mating end thereby completely to enclose and shield the chip carrier in the cavity, the shield being anchored in a fingerpiece at one axial end, an anti-overstress eye extending from a side of the fingerpiece and the latch arm means having a rearwardly extending projection received in the eye which restricts the movement of the latch arm means away from the body.
