Abstract
Abstract A shielded housing for a connector connected to a multiconductor shielded cable comprises two mating shells and a ferrule. The ferrule is placed around the cable and the shielding braid wires are folded back over the ferrule. The shells clamp around the ferrule to make good electrical contact with the cable shield and also to provide strain relief for the cable.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
153 words
A shielded housing for a connector attached to a cable having one or more insulated conductors in a common conductive shield covered by an insulative plastic sheath, the housing comprising: a generally cylindrical ferrule for surrounding a portion of the insulative plastic sheath on the end of the cable attached to the connector and having a plurality of longitudinal slots that allow the ferrule to be compressed and engage the sheath; and mating first and second shells, each shell having connector retaining means for retaining and making electrical contact with the connector, and a cable recess for retaining the cable by compressing the ferrule sufficiently to deform the sheath and cause some of the sheath material to flow into the slots and making electrical contact with the conductive shield by clamping the shield between the outer surface of the ferrule and the cable recess when the first and second shells are mated together.
Claim 2
Dependent Claim
153 words
A shielded housing for a connector attached to a cable having one or more insulated conductors in a common conductive shield covered by an insulative plastic sheath, the housing comprising: a generally cylindrical ferrule for surrounding a portion of the insulative plastic sheath on the end of the cable attached to the connector and having a plurality of longitudinal slots that allow the ferrule to be compressed and engage the sheath; and mating first and second shells, each shell having connector retaining means for retaining and making electrical contact with the connector, and a cable recess for retaining the cable by compressing the ferrule sufficiently to deform the sheath and cause some of the sheath material to flow into the slots and making electrical contact with the conductive shield by clamping the shield between the outer surface of the ferrule and the cable recess when the first and second shells are mated together.
Claim 3
Dependent Claim
31 words
A shielded housing as in claim 1 wherein the ferrule has a groove in its outer surface and the cable recesses have ridges for mating with the groove in the ferrule.
Claim 4
Dependent Claim
42 words
A shielded housing as in claim 2 wherein the connector retaining means comprises a lip with a groove therein on each shell and the shells have interlocking ridges and grooves for aligning the shells and providing a seal against electromagnetic radiation leakage.
Claim 5
Dependent Claim
140 words
A connector assembly for a multiconductor shielded cable covered by a plastic sheath comprising: a connector connected to conductors in the cable; a generally cylindrical ferrule surrounding a portion of the cable, having a plurality of longitudinal slots along a portion of its length and having an outer surface over which a portion of the shield is placed; a housing comprising two mating shells having connector retaining means for retaining the connector and having recesses that form cable retaining means for engaging the ferrule and the portion of the shield placed over the ferrule and for clamping the ferrule to the cable to compress the ferrule around a portion of an outer surface of the cable to deform the plastic sheath and cause some of the plastic sheath material to flow into the slots for preventing rotation of the cable.
Claim 6
Dependent Claim
140 words
A connector assembly for a multiconductor shielded cable covered by a plastic sheath comprising: a connector connected to conductors in the cable; a generally cylindrical ferrule surrounding a portion of the cable, having a plurality of longitudinal slots along a portion of its length and having an outer surface over which a portion of the shield is placed; a housing comprising two mating shells having connector retaining means for retaining the connector and having recesses that form cable retaining means for engaging the ferrule and the portion of the shield placed over the ferrule and for clamping the ferrule to the cable to compress the ferrule around a portion of an outer surface of the cable to deform the plastic sheath and cause some of the plastic sheath material to flow into the slots for preventing rotation of the cable.
Claim 7
Dependent Claim
50 words
A connector assembly as in claim 4 wherein the outer surface of the ferrule includes a groove over which a portion of the shield is placed and the recess in each shell includes a ridge that mates with the groove in the ferrule to make electrical contact with the shield.
Claim 8
Dependent Claim
24 words
A connector assembly as in claim 5 wherein the first and second shells are identical and have mating ribs and recesses about their peripheries.
Claim 9
Dependent Claim
32 words
A connector assembly as in claim 6 wherein the cable shield is a wire braid and the portion of the shield placed over the outer surface of the ferrule comprises unbraided wires.
Claim 10
Dependent Claim
28 words
A connector assembly as in claim 7 wherein the connector has a flange and the connector retaining means includes a recess in each shell for engaging the flange.
