## Abstract

An EMI shielding enclosure for a cable connector is formed of aluminum and has an aperture 44 therein to receive potting compound 46 to secure the wires 28 to the connector body. The braided inner cover 26 of the cable 24 is formed into a pig tail 34 and is secured in the back-shell 40 by the potting compound 46. The outer braided cover 30 of the cable, which is the braided shield, is also terminated in a pig tail 36 which is folded back on itself and through the end plate or strain relief means 38 of the enclosure. The strain relief means 38 is welded 42 to the back-shell 40 and a rivet 48 plugs the potting aperture 44 in the back-shell 40 after which a rubberized boot 50 is formed over the enclosure. Prior to forming the boot 50, the back-shell 40 is staked or secured to the connector body. The result is a solid, secure EMI shielded enclosure for a cable connector and operates with either a straight or elbow back-shell 40.

## Claims

### Claim 1

An EMI shielded connector assembly comprising a cable connector body, a cable having at least a first cover overlying jacketed wires, a second braided cover overlying the first cover, the cable having the jacketed wires therein extending beyond the first and second covers and inserted in the connector body, each of the first and second covers terminating in respective tails; and an aliminum back-shell receiving the cable at one end and press fit to the connector body at the other end, the back-shell having an aperture therein adapted to receive potting compound within the shell; said assembly characterized by:
first means encircling the cable and having a slot means therein receiving and securing the tail of the second braided cover;
second means securing said first means to the back-shell;
potting compound filling the interior of the back-shell and securing the tail of the first cover and the jackets of the wires therein; and
means comprised of aluminum closing the aperture and with the back-shell and said first means forming an EMI shield over the cable and connector body.

### Claim 2 (depends on 1)

An EMI shielded connector assembly according to claim 1 additionally including a molded rubber boot encapsulating said back-shell and said closing means; said boot sealingly encircling said cable where it is received in said first means.

### Claim 3 (depends on 1, 2)

An EMI shielded connector assembly according to claim 1 or 2 wherein said first cover is formed by braiding polytetrafluoroethylene coated fiberglass thread around said jacketed wires and terminating said first cover in a braided tail.

### Claim 4 (depends on 3)

An EMI shielded connector assembly according to claim 3 wherein said second cover is formed by braiding nickel wire around said first cover and terminating said second cover in a braided tail.
