Abstract
Abstract An EMI/ESD shielded D cable-connector assembly wherein the shielding between the cable shield and metal shell of the connector is afforded by a length of wire mesh surrounding the conductors and joining said shield to said shell. A shielding plate contacting said mesh and positioned for contact to the mating D connector assures a continuous ground.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
125 words
An EMI/ESD shielded connector and cable assembly comprising a length of cable comprising a plurality of conductors, a shield and outer insulating sheath, a connector comprising individual contacts connected to said conductors and having a conductive metal shroud having a peripheral flange, said conductors extending from said sheath and said shield extending from said insulating sheath, a length of conductive wire mesh wrapped about said conductors and contacting said shroud along one edge and the other edge being wrapped about said exposed shield, a shield plate having a plate portion conductively coupled to said mesh and being formed to cover a portion of said flange and extend along said connector, and a cover extending over said mesh from said cable sheath to said connector flange.
Claim 2
Dependent Claim
125 words
An EMI/ESD shielded connector and cable assembly comprising a length of cable comprising a plurality of conductors, a shield and outer insulating sheath, a connector comprising individual contacts connected to said conductors and having a conductive metal shroud having a peripheral flange, said conductors extending from said sheath and said shield extending from said insulating sheath, a length of conductive wire mesh wrapped about said conductors and contacting said shroud along one edge and the other edge being wrapped about said exposed shield, a shield plate having a plate portion conductively coupled to said mesh and being formed to cover a portion of said flange and extend along said connector, and a cover extending over said mesh from said cable sheath to said connector flange.
Claim 3
Dependent Claim
14 words
An assembly according to claim 1 wherein said mesh is connected to said shield.
Claim 4
Dependent Claim
25 words
An assembly according to claim 2 wherein said mesh is connected to said shield by a spring urging said mesh into contact with said shield.
Claim 5
Dependent Claim
15 words
An assembly according to claim 3 wherein said spring is a convolutely wound steel spring.
Claim 6
Dependent Claim
22 words
