1. 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.
