Abstract
Abstract This disclosure describes a connector for a communications coaxial cable. The connector structure includes a collapsible bushing which is wedged into a positive grip with the cable jacket, and a separate wedge-type bushing to grip the outer conductor. A resilient seal is afforded around the center conductor. Placement of the cable in the connector and of the latter onto equipment housing requires no special tools.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
165 words
For a coaxial communications cable consisting of a center conductor, a corrugated outer conductor and a plastic jacket surrounding said outer conductor, a connector comprising: a chambered main body comprising a central internal tapered section and an inner sealing dam adjacent thereto containing a sealing compound; a first bushing having a cylindrical section fitting under the surface of said outer conductor at a selected point and a conic section adjacent thereto; a second bushing comprising a tapered body with plural interior annular teeth for gripping said jacket, and a cylindrical end comprising exterior longitudinal slots; first means for driving said first bushing conic section into wedging engagement with said main body tapered section to grip said outer conductor therebetween; and second means for compressing said second bushing teeth into gripping engagement with said jacket, said second means also driving said cylindrical end into said sealing dam to hydraulically disperse said sealing compound along the interfaces of said second bushing, said jacket and said second means.
Claim 2
Dependent Claim
165 words

Claim 3
Dependent Claim
35 words
A connector pursuant to claim 1, wherein said first means is a drive body comprising a first flanged end for threadably engaging said main body chamber and affecting said wedging engagement with its end face.
Claim 4
Dependent Claim
61 words
A connector pursuant to claim 2 wherein said drive body further comprises a second flanged end with an annular interior seat, a pair of plastic washers sealably engaged in said seat, and a compliant washer supported between said discs, the compliant washer having a central orifice less than the diameter of said central conductor for affecting a seal around the latter.
Claim 5
Dependent Claim
67 words
A connector pursuant to claim 3, wherein said drive body second flanged end further comprises a threaded interior section with a locking nut thereon and a depressed end groove for receiving a snap-mountable metal ring, and said connector further comprises a threaded anchor fitting slidably engaged on said flange between said ring and said locking nut, said fitting being held therebetween by action of said locking nut.
