Connector for semirigid coaxial cable

Claim 2

An electrical connector for terminating semirigid coaxial cable, comprising: a bored tubular shell member having rearward bore means of relatively large inner diameter inwardly contoured toward forward bore means having a relatively smaller inner diameter dimensioned to receive the cable therethrough; an adhesive is applied onto said rearward bore means and is disposed within a protective film; coupling means on said tubular member; bored gripping means having a rearward collar portion dimensioned to closely receive the cable therethrough, and having a plurality of spline fingers extending forward from the periphery of said collar portion defining therebetween a profiled opening of a dimension substantially equal to the cable diameter, said gripping means being rearwardly disposed of said tubular member, whereby, upon moving said gripping means forwardly into said rearward bore means, said spline fingers are resiliently deflected inwardly along said contour to embed into an outer conductive layer of the cable and said protective film is ruptured causing said adhesive to flow between engaging surfaces of said shell member and said gripping means whereby when the adhesive cures, the adhesive seals the connection thereby increasing the torque and tensile resistance thereof.

Claim 3

A connector as set forth in claim 1, further comprising gasket means in peripheral engagement with said tubular shell member for sealing the interface of said connector.

Claim 4

A connector as set forth in claim 1, said tubular shell member having an outwardly directed external annular flange, and said coupling means comprising a nut having rearward flange means in engagement against said shell member flange.

Claim 5

A connector as set forth in claim 1, said center contact means comprising a forward length of the cable center conductor adapted to project forward a distance free of the outer conductive layer, and free of an intermediate dielectric layer of the cable disposed between the outer layer and the center conductor.

Claim 6

A connector as set forth in claim 1, said spline fingers each being tapered to a point.

Claim 7

A connector as set forth in claim 1, said tubular shell member having longitudinal grooves within rearward walls defining said rearward bore means, said grooves engaging said gripping means collar portion for resisting rotational motion of said gripping means within said tubular shell member.

Claim 8

A connector as set forth in claim 1, said gripping means having an outwardly directed annular flange at a rearward end adjacent a rearward end of said tubular shell member.

Claim 9

A connector as set forth in claim 1, wherein an inside surface of said gripping means includes grooves which engage the outer conductive cable layer when the gripping means is moved into the shell member.

Claim 10

A connector as set forth in claim 8, wherein said inside surface has said adhesive applied thereto so that said adhesive is disposed between said inside surface and the outer conductive layer of the cable.

Claim 11

A connector as set forth in claim 1, said center contact means comprising a terminal member affixed to a forward end of the cable center conductor.

Claim 12

A connector as set forth in claim 10, further comprising a dielectric insert having a bore therethrough, said forward bore means receiving said insert therein with said terminal member positioned within said insert bore.

Claim 13

An electrical connector for terminating semirigid coaxial cable, comprising: a bored tubular shell member having rearward bore means of relative large inner diameter inwardly contoured toward forward bore means having a relatively smaller inner diameter dimensioned to receive the cable therethrough, and said shell member having longitudinally grooved wall means defining said rearward bore means; an adhesive is applied onto said grooved wall means and is disposed within a protective film; coupling means on said tubular member; bored gripping means having a rearward collar portion dimensioned to closely receive the cable therethrough and having an outwardly directed annular flange at a rearward end, and said gripping means having a plurality of tapered spline fingers extending forward from the periphery of said collar portion defining therebetween a profiled opening of a dimension substantially equal to the cable diameter, said gripping means being rearwardly disposed of said tubular member, whereby, upon moving said gripping means forwardly into said rearward bore means with said gripping means flange disposed adjacent a rearward end of said tubular member, said spline fingers are resiliently deflected inwardly along said contour to embed into an outer conductive layer of the cable, said grooved wall means engaging said gripping means collar portion and said protective film is ruptured causing said adhesive to flow between engaging surfaces of said shell member and said gripping means whereby when the adhesive cures, the adhesive seals the connection thereby increasing the torque and tensile resistance thereof.

Claim 14

An electrical connector for terminating semirigid coaxial cable, comprising: a bored tubular shell member having rearward bore means of relative large inner diameter inwardly contoured toward forward bore means having a relatively smaller inner diameter dimensioned to receive the cable therethrough, and said shell member having longitudinally grooved wall means defining said rearward bore means; an adhesive is applied onto said grooved wall means and is disposed within a protective film; coupling means on said tubular member; bored gripping means having a rearward collar portion dimensioned to closely receive the cable therethrough and having an outwardly directed annular flange at a rearward end, and said gripping means having a plurality of tapered spline fingers extending forward from the periphery of said collar portion defining therebetween a profiled opening of a dimension substantially equal to the cable diameter, said gripping means being rearwardly disposed of said tubular member, whereby, upon moving said gripping means forwardly into said rearward bore means with said gripping means flange disposed adjacent a rearward end of said tubular member, said spline fingers are resiliently deflected inwardly along said contour to embed into an outer conductive layer of the cable, said grooved wall means engaging said gripping means collar portion and said protective film is ruptured causing said adhesive to flow between engaging surfaces of said shell member and said gripping means whereby when the adhesive cures, the adhesive seals the connection thereby increasing the torque and tensile resistance thereof.

Claim 15

An electrical connector as set forth in claim 12, wherein grooves extend along an inner surface of said gripping means and engage the cable to resist rotational movement of the cable within said gripping means.

Claim 16

An electrical connector as set forth in claim 13, wherein said adhesive is disposed along said inner surface so that said adhesive is disposed between said inner surface and the outer conductive layer of the cable.
