Electrical cable connector
First Claim
1. A cable connector for connecting a cable to a mating connector having at least one electrical lead and an integral coupling mechanism, the cable having a cable jacket surrounding a layer of electrically-conductive material, the electrically-conductive layer including an exposed portion not covered by the cable jacket, the electrically-conductive layer surrounding at least one electrical lead having an insulting layer surrounding a wire, the cable connector comprising:
- a coupling ring having an integral coupling mechanism and an interior surface placed around the cable, said coupling mechanism of said coupling ring engageable with the integral coupling mechanism of the mating connector to connect the mating connector with said coupling ring;
a tubular shield extending from said coupling ring and surrounding the cable and the exposed portion of the electrically-conductive layer; and
an insulating insert placed within said shield, said insulating insert surrounding an exposed end of the at least one electrical lead of the cable;
wherein a portion of said shield is crimped to create multiple indents in secure engagement with the cable for mechanical retention and an electrical contact between said shield and the exposed portion of the electrically-conductive layer.

Abstract
What is disclosed is a electrical cable connector to shield against EMI, ESD and EMC emissions. The cable connector is used to connect an electrical cable to a mating connector having an integral connecting mechanism such as a threaded exterior surface. The cable has a cable jacket surrounding a braid which surrounds at least one signal lead. The cable jacket is removed over a portion of the cable to expose the braid. The exposed braid is then folded back over the cable jacket to create a braid surface. A coupling ring, which has an integral coupling mechanism such as a threaded interior surface, is placed over the end of the cable. A shield is placed in the coupling ring and a portion of the shield is crimped over the braid surface. An optional wave spring may be placed between the coupling ring and the shield. An insulating insert is placed between the end of the one cable and the mating connector. The coupling ring is screwed onto the mating connector. The connector thus has electrical continuity between the braid, the cylindrical shield and the coupling ring to shield against EMI, ESD and EMC emissions.

11. A method of fabricating a cable connector to connect a cable to a mating connector having an integral coupling mechanism, the cable having a cable jacket, a layer of electrically-conductive material surrounded by the cable jacket, and at least one electrical lead surrounded by the electrically-conductive layer, the method comprising the steps of:
-
removing the cable jacket from a portion of one end of the cable to expose a portion of the electrically-conductive layer; placing the cable through a coupling ring having an integral coupling mechanism engageable with the integral coupling mechanism of the mating connector; placing a tubular shield over the exposed portion of the electrically-conductive layer such that said shield is extending from said coupling ring; crimping a portion of said shield to create multiple indents in secure engagement with the cable for mechanical retention and electrical contact between the shield and the exposed portion of the electrically-conductive layer; and placing an insulating insert within said shield so that an exposed end of the at least one electrical lead of the cable is contained within the insulating insert. - View Dependent Claims (16)
