Abstract
Abstract A connector assembly for connecting a double-shielded cable to a double-shielded RFI box employs an inner tubular conductive member for extending through an aperture in the box to connect a first shield of the cable to the inner shield of the box. An insulating ring is mounted on the inner member and an outer tubular conductive member is mounted on the ring. The second shield of the cable and the outer shield of the box are connected to the outer conductive member.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
203 words
A composite connector assembled with an electrically nonconductive member having first and second isolated and electrically conductive surfaces, and a cable having a central conductor, a first layer of insulation surrounding the conductor, a first metal shield concentric with and external of the first layer of insulation, a second layer of insulation concentric with and external of the first shield, and a second metal shield concentric with and external of the second layer of insulation, which comprises: a first connector member of electrically conductive material having one portion electrically connected to the first metal shield and another portion in electrical contact with the first electrically conductive surface, the first connector member being electrically isolated from the second shield and the second conductive surface; an insulating member mounted on the first connector member; and a second connector member of electrically conductive material mounted on the insulating member and being electrically isolated from the first connector member by the insulating member, one portion of the second connector member being electrically connected to the second metal shield and another portion being in elEctrical contact with the second electrically conductive surface, the second connector member being electrically isolated from the first shield and the first conductive surface.
Claim 2
Dependent Claim
203 words
A composite connector assembled with an electrically nonconductive member having first and second isolated and electrically conductive surfaces, and a cable having a central conductor, a first layer of insulation surrounding the conductor, a first metal shield concentric with and external of the first layer of insulation, a second layer of insulation concentric with and external of the first shield, and a second metal shield concentric with and external of the second layer of insulation, which comprises: a first connector member of electrically conductive material having one portion electrically connected to the first metal shield and another portion in electrical contact with the first electrically conductive surface, the first connector member being electrically isolated from the second shield and the second conductive surface; an insulating member mounted on the first connector member; and a second connector member of electrically conductive material mounted on the insulating member and being electrically isolated from the first connector member by the insulating member, one portion of the second connector member being electrically connected to the second metal shield and another portion being in elEctrical contact with the second electrically conductive surface, the second connector member being electrically isolated from the first shield and the first conductive surface.
Claim 3
Dependent Claim
97 words
A connector assembly as recited in claim 1, wherein: the nonconductive member has an aperture extending between the first and the second conductive surfaces; the first connector member comprises a first tubular cylindrical member having a flange at one end, positioned with the cylindrical member extending through the aperture with the flange is in conductive engagement with the first surface; the insulating member comprises a cylindrical sleeve circumferentially disposed about a portion of the first cylindrical member and extending through the aperture, so that the first cylindrical member is spaced from the surface defined by the aperture.
Claim 4
Dependent Claim
60 words
A connector assembly as recited in claim 2, wherein; the second connector member comprises a second tubular cylindrical member having a second flange at one end and being circumferentially disposed about the insulating member with the second flange being in conductive engagement with the second surface and the second cylindrical member being spaced from the first by the insulating member.
Claim 5
Dependent Claim
63 words
A connector assembly as recited in claim 3, wherein the first shield is circumferentially disposed about a portion of the first cylindrical member; and wherein the first shield is connected to the first cylindrical body by a first deformable crimp ring surrounding the first shield, and crimped on the first shield securing the first shield in conducting engagement with the first cylindrical member.
Claim 6
Dependent Claim
86 words
A connector assembly as recited in claim 4, wherein the second shield is connected to the second cylindrical member by: a second deformable crimp ring, spaced between the second layer of insulation and the second shield; a third deformable and conductive crimp ring surrounding the second shield and crimped on the second shield conductively engaging the second shield and confining the second shield between the second and third rings; and means conductively engaging the third deformable ring and a portion of the second conductive cylindrical member.
Claim 7
Dependent Claim
46 words
A connector assembly as recited in claim 5, wherein the means conductively engaging the third ring and the second conductive cylindrical body comprises: a jamnut in engagement with the second conductive cylindrical member to deflect a portion of the member into engagement with the third ring.
Claim 8
Dependent Claim
79 words
A connector as recited in claim 6, wherein: the cable is arranged with the central conductors passing through the bore in the first cylindrical member; and the second cylindrical member is concentric with the first cylindrical member, and has a axial bore throughout its length permitting passage of the central conductors and permitting entry of the first shield, the first insulative layer, the second deformable crimp ring, the second shield, and the third deformable crimp ring into the bore.
