Abstract
Abstract A connector for attachment to the end of a coaxial cable having a core electrode and a conductive sheath electrode which 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 cap formed with a forwardly facing internal cam surface for engagement with the external cam surfaces of the skirt screws on to the housing so that interaction of the cam surfaces causes the tongues to be flexed radially inwardly into gripping engagement with the sheath electrode of a cable disclosed within the connector for electrical contact therewith. A radially inwardly compressible and electrically conductive collet sleeve coaxially disposed within the housing is adapted to receive the core electrode of the said cable and to be radially inwardly compressed by an electrically insulating compressible bushing disposed about the collet sleeve. The bushing has diametrically opposed projections extending through the tubular skirt defining rearwardly facing external cam surfaces for engagement by a second forwardly facing internal cam surface formed in the tubular cap such that radially inward movement is concurrently transmitted to the bushing and collet sleeve for simultaneous gripping of the core electrode and sheath electrode without any torsional shearing action between the said electrodes.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
328 words
A connector for securement to the end of a coaxial cable having a sheath electrode and a core electrode which comprises: a hollow housing having a rearwardly extending and peripherally discontinuous electrically conductive tubular skirt for radially inward compression into gripping engagement and electrical contact with the sheath electrode of a coaxial cable extending forwardly into said skirt, said tubular skirt being formed with an external cam surface and at least one longitudinal slot; a radially inwardly compressible and electrically conductive collet sleeve mounted generally axially within said housing for receiving an exposed forward end portion of the core electrode of the coaxial cable inserted into said connector; a radially inwardly compressible and electrically insulating bushing generally coaxially disposed around said collet sleeve and having at least one projection extending through said slot formed in said tubular skirt, said projection defining an external cam surface; a hollow tubular cap having associated therewith at least one internal cam surface for conjoint axial movement with said cap and for engagement with said external cam surface of said tubular skirt and said external cam surface of said bushing projection when said cap is disposed coaxially around said tubular skirt whereby on forward axial movement of said cap relative to said housing, said cap is adapted to cause radially inward compression of said tubular skirt into gripping engagement and electrical contact with the sheath electrode of the coaxial cable disposed within said tubular skirt and adapted to cause radially inward compression of said bushing and said collet sleeve to move said collet sleeve into gripping engagement and electrical contact with the core electrode of the cable; said compression of the collet sleeve occurring concurrently with the compression of the tubular skirt for simultaneous gripping of the core electrode and sheath electrode without any torsional shearing action between the said electrodes; and co-operating means on said housing and on said cap for retaining said cap in a desired axial position on said housing.
Claim 2
Dependent Claim
328 words
A connector for securement to the end of a coaxial cable having a sheath electrode and a core electrode which comprises: a hollow housing having a rearwardly extending and peripherally discontinuous electrically conductive tubular skirt for radially inward compression into gripping engagement and electrical contact with the sheath electrode of a coaxial cable extending forwardly into said skirt, said tubular skirt being formed with an external cam surface and at least one longitudinal slot; a radially inwardly compressible and electrically conductive collet sleeve mounted generally axially within said housing for receiving an exposed forward end portion of the core electrode of the coaxial cable inserted into said connector; a radially inwardly compressible and electrically insulating bushing generally coaxially disposed around said collet sleeve and having at least one projection extending through said slot formed in said tubular skirt, said projection defining an external cam surface; a hollow tubular cap having associated therewith at least one internal cam surface for conjoint axial movement with said cap and for engagement with said external cam surface of said tubular skirt and said external cam surface of said bushing projection when said cap is disposed coaxially around said tubular skirt whereby on forward axial movement of said cap relative to said housing, said cap is adapted to cause radially inward compression of said tubular skirt into gripping engagement and electrical contact with the sheath electrode of the coaxial cable disposed within said tubular skirt and adapted to cause radially inward compression of said bushing and said collet sleeve to move said collet sleeve into gripping engagement and electrical contact with the core electrode of the cable; said compression of the collet sleeve occurring concurrently with the compression of the tubular skirt for simultaneous gripping of the core electrode and sheath electrode without any torsional shearing action between the said electrodes; and co-operating means on said housing and on said cap for retaining said cap in a desired axial position on said housing.
Claim 3
Dependent Claim
90 words
A connector as claimed in claim 1, in which said tubular skirt is longitudinally divided by at least one pair of diametrically opposed slits and by a pair of diametrically opposed slots into a plurality of peripherally spaced apart and rearwardly extending, radially inwardly and reSiliently compressible tongues having an external cam surface formed collectively thereon, and said bushing having a pair of diametrically opposed projections formed thereon, said slots permitting said bushing projections to extend therethrough for engagement by an internal cam surface formed in the hollow tubular cap.
Claim 4
Dependent Claim
20 words
A connector as claimed in claim 2, in which said slits and said slots are equispaced about the tubular skirt.
Claim 5
Dependent Claim
26 words
A connector as claimed in claim 1, in which said tubular skirt is internally serrated for gripping engagement with the coaxial cable sheath electrode disposed therewithin.
Claim 6
Dependent Claim
25 words
A connector as claimed in claim 2, in which said tongues are internally serrated for gripping engagement with the coaxial cable sheath electrode disposed therewithin.
Claim 7
Dependent Claim
57 words
A connector as claimed in claim 1, in which said cap has a pair of axially spaced apart forwardly facing internal cam surfaces, one of said cam surfaces adapted to engage the external cam surface of the tubular skirt and the other of said cam surfaces adapted to engage the external cam surface of the bushing projection.
Claim 8
Dependent Claim
20 words
A connector as claimed in claim 2, in which said cap internal cam surface is a frusto-conical or spherical surface.
Claim 9
Dependent Claim
19 words
A connector as claimed in claim 6, in which said cap internal cam surfaces are frusto-conical or spherical surfaces.
Claim 10
Dependent Claim
18 words

Claim 11
Dependent Claim
23 words
A connector as claimed in claim 9, in which said tubular skirt external cam surface is a rearwardly facing frusto-conical or spherical surface.
Claim 12
Dependent Claim
