Abstract
Abstract A shielded cable system having a connector, a shielded cable and an interface of a pressure sensitive adhesive electrically conductive performed insert which provides effective noise suppression between the connector and cable. In manufacture the insert is folded about and positioned in contact with the connector and the cable suppression sheath (usually a metal braid) is then preferably held in good electrical contact with the connector and sheath by a shrinkable molded outer protective portion e.g. of dielectric material.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
122 words
A cable system comprising a connector having a plurality of pins supported in an insulator which is itself supported in a metal portion, a cable having a plurality of wires in an electrically conductive cable shield, said wires coupled to said pins, a thin preformed electrically conductive, conductive particle loaded pressure sensitive adhesive carrying insert folded at predetermined fold lines and positioned about a metal portion of the connector and the electrically conductive cable shield acting as an enclosing extension of said shield with the adhesive of said insert in contact with said connector and said shield and means over said insert for urging said adhesive portion of said insert against said connector and said shield to aid in electrical contact therewith.
Claim 2
Dependent Claim
122 words
A cable system comprising a connector having a plurality of pins supported in an insulator which is itself supported in a metal portion, a cable having a plurality of wires in an electrically conductive cable shield, said wires coupled to said pins, a thin preformed electrically conductive, conductive particle loaded pressure sensitive adhesive carrying insert folded at predetermined fold lines and positioned about a metal portion of the connector and the electrically conductive cable shield acting as an enclosing extension of said shield with the adhesive of said insert in contact with said connector and said shield and means over said insert for urging said adhesive portion of said insert against said connector and said shield to aid in electrical contact therewith.
Claim 3
Dependent Claim
26 words
The system of claim 1 in which said insert comprises a metal foil coupled to an adhesive layer comprising a polymer and an electrically conductive particles.
Claim 4
Dependent Claim
40 words
The system of claim 1 or 2 in which the cable shield is metal braid, and said particles are selected from the class consisting of silver, silver coated aluminum, silver coated copper, silver coated glass, nickel and silver coated nickel.
Claim 5
Dependent Claim
20 words
The system of claim 2 in which said particles have an average size greater than the thickness of the polymer.
Claim 6
Dependent Claim
34 words
The system of claim 1, 2 or 4 in which there is provided a dielectric insulator over the wires between said connector and said cable shield which acts as a support for the insert.
Claim 7
Dependent Claim
18 words
The system of claim 1 in which said means for urging is a plastic which shrinks upon cooling.
Claim 8
Independent Claim
109 words
The method of making a shield cable system comprising wrapping and folding along predetermined lines a preformed electrically conductive pressure sensitive adhesive insert about a metal portion of the connector and a shield of a cable with the adhesive in contact therewith and forming shrinkable means about said insert to insure good electrical conductivity between said connector and said cable shield, said insert comprising a metal foil coupled to an adhesive layer comprising a polymer and electrically conductive particles, said insert being folded at predetermined fold lines to act as an enclosing extension of said shield tightly held in good electrical contact with said connector and said cable shield.
Claim 9
Independent Claim
109 words
The method of making a shield cable system comprising wrapping and folding along predetermined lines a preformed electrically conductive pressure sensitive adhesive insert about a metal portion of the connector and a shield of a cable with the adhesive in contact therewith and forming shrinkable means about said insert to insure good electrical conductivity between said connector and said cable shield, said insert comprising a metal foil coupled to an adhesive layer comprising a polymer and electrically conductive particles, said insert being folded at predetermined fold lines to act as an enclosing extension of said shield tightly held in good electrical contact with said connector and said cable shield.
