Abstract

Abstract A connector for attachment to the end of a coaxial cable having an axial core electrode or conductor and a conductive sheath electrode or conductor includes a housing having an integral tubular skirt formed from four rearwardly extending tongues collectively formed with a rearwardly facing external cam surface. A tubular cover sleeve formed with a forwardly facing internal cam surface for engagement with the external cam surface of the tongues screws onto the housing so that interaction of the cam surfaces causes the tongues to be flexed radially inwardly into gripping engagement with a cable disposed within the connector and into electrical contact with the conductive sheath electrode of that cable. Usefully, a radially inwardly compressible and electrically conductive collet sleeve is coaxially disposed within the tongues between their forward and rearward ends so as to receive an exposed forward end portion of the core electrode of the cable. An electrically insulating and radially inwardly compressible bushing disposed about the collet sleeve serves to transmit radially inward movement from the tongues to the collet sleeve so as to provide simultaneous gripping of the core electrode without any torsional shearing action between the sheath and core electrodes.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 341 words
A connector for securement to the end of coaxial cable having a core electrode and a conductive sheath electrode and which connector comprises a hollow housing having integral therewith a rearwardly extending and peripherally discontinuous electrically conductive tubular skirt for radially inward compression into gripping engagement with a coaxial cable extending forwardly into said skirt and into electrical contact with the conductive sheath electrode of such a coaxial cable, said tubular skirt being formed with a rearwardly facing external surface; a hollow tubular cover sleeve having associated therewith a forwardly facing internal cam surface for conjoint axial movement with said cover sleeve and for engagement with said rearwardly facing external surface of said tubular skirt when said cover sleeve is disposed coaxially around said tubular skirt and adapted to cause radially inward compression of said tubular skirt into gripping engagement with the coaxial cable disposed within said tubular skirt and into electrical contact with the conductive sheath electrode of that coaxial cable on forward axial movement of said cover sleeve relative to said housing; co-operating means on said housing and on saId cover sleeve for retaining said cover sleeve in a fixed forward axial position on said housing in turn to maintain said tubular skirt radially inwardly compressed and in gripping engagement with the coaxial cable disposed within said tubular skirt and in electrical contact with the conductive sheath electrode of that cable; a radially inwardly compressible and electrically conductive collet sleeve mounted generally axially within said tubular skirt of said housing for receiving an exposed forward end portion of the core electrode of the coaxial cable inserted into said connector; and a radially inwardly compressible and electrically insulating bushing coaxially disposed around said collet sleeve and within said tubular skirt whereby, on said radially inward compression of said tubular skirt on forward axial movement of said cover sleeve relative to said housing, said bushing and said collet sleeve are radially inwardly compressed to move said collet sleeve into gripping engagement and electrical contact with the core electrode of the cable.
Claim 2
Dependent Claim 341 words
A connector for securement to the end of coaxial cable having a core electrode and a conductive sheath electrode and which connector comprises a hollow housing having integral therewith a rearwardly extending and peripherally discontinuous electrically conductive tubular skirt for radially inward compression into gripping engagement with a coaxial cable extending forwardly into said skirt and into electrical contact with the conductive sheath electrode of such a coaxial cable, said tubular skirt being formed with a rearwardly facing external surface; a hollow tubular cover sleeve having associated therewith a forwardly facing internal cam surface for conjoint axial movement with said cover sleeve and for engagement with said rearwardly facing external surface of said tubular skirt when said cover sleeve is disposed coaxially around said tubular skirt and adapted to cause radially inward compression of said tubular skirt into gripping engagement with the coaxial cable disposed within said tubular skirt and into electrical contact with the conductive sheath electrode of that coaxial cable on forward axial movement of said cover sleeve relative to said housing; co-operating means on said housing and on saId cover sleeve for retaining said cover sleeve in a fixed forward axial position on said housing in turn to maintain said tubular skirt radially inwardly compressed and in gripping engagement with the coaxial cable disposed within said tubular skirt and in electrical contact with the conductive sheath electrode of that cable; a radially inwardly compressible and electrically conductive collet sleeve mounted generally axially within said tubular skirt of said housing for receiving an exposed forward end portion of the core electrode of the coaxial cable inserted into said connector; and a radially inwardly compressible and electrically insulating bushing coaxially disposed around said collet sleeve and within said tubular skirt whereby, on said radially inward compression of said tubular skirt on forward axial movement of said cover sleeve relative to said housing, said bushing and said collet sleeve are radially inwardly compressed to move said collet sleeve into gripping engagement and electrical contact with the core electrode of the cable.
Claim 3
Dependent Claim 355 words
A connector as claimed in claim 1 in which said housing is formed on a forward end thereof with a forwardly extending second said peripherally discontinuous and electrically conductive tubular skirt for radially inward compression into gripping engagement with a second coaxial cable inserted into a forward end of said connector and into electrical contact with the conductive sheath electrode of such a second coaxial cable, said second tubular skirt being formed with a forwardly facing external cam surface, which connector additionally comprises a second said hollow tubular cover sleeve having associated therewith a rearwardly facing internal cam surface for conjoint coaxial movement with said second cover sleeve and for engagement with said forwardly facing external cam surface of said second tubular skirt when said second cover sleeve is disposed coaxially around said second tubular skirt and adapted to cause radially inward compression of said second tubular skirt into gripping engagement with said second coaxial cable and into electrical contact with the conductive sheath electrode of that second coaxial cable on rearward axial movement of said second cover sleeve relative to said housing, in which said collet sleeve is adapted to receive an exposed rearward end portion of the core electrode of the second coaxial cable inserted into said connector, which connector additionally comprises a second said radially inwardly compressible and electrically insulating bushing coaxially disposed around said collet sleeve within said second tubular skirt whereby, on radially inward compression of said second tubular skirt on rearward axial movement of said second cover sleeve relative to said housing, said second bushing and said collet sleeve are radially inwardly compressed to move said collet sleeve into gripping engagement and electrical contact with said exposed rearward end portion of the core electrode of the second coaxial cable, and which connector additionally comprises cooperating means on said housing and on said second cover sleeve for retaining said second cover sleeve in a fixed rearward axial position on said housing in turn to maintain said second tubular skirt radially inwardly compressed and in engagement with the outer conductive sheath of the second coaxial cable disposed within said tubular skirt.
