Crimpless coaxial cable connector with pull back cable engagement

A connector for use with a coaxial cable of the type having a core with a central wire conductor and a foil conductor and having a deformable outer insulating jacket, said connector also being for use with a coupling unit, said connector comprising:

• a generally cylindrical body open at both ends, having a mating portion at one end engageable with said coupling unit, and at the other end being adapted to receive said cable;
• a bushing with a bore of a diameter to closely receive said cable, mounted within said body proximal to said other end thereof;
• an annular mandrel with a bore of a diameter to closely receive said core of said cable, housed within said body proximal to said one end thereof, said mandrel having a sleeve adapted to engage the cable beneath said jacket, contacting said foil, to thereby stretch and increase the outer diameter of the jacket to a diameter greater than the internal diameter of the bushing, the sleeve being engageable with the cable by pushing the mandrel and the cable together;
• said mandrel being movable longitudinally within said body from a receiving position in which the sleeve is not surrounded by the bushing whereby the sleeve may be engaged to the cable, to a holding position in which the sleeve is at least partially within the bushing whereby the jacket is frictionally engaged by the bushing to retain the cable in the connector, the mandrel being displaced to the holding position by pulling the cable away from the connector after engagement of the cable with the mandrel.

A combination of a coaxial cable and a connector for use with a coupling unit, comprising:

• a coaxial cable having a core with a central wire conductor and a foil conductor, and having a deformable outer insulating jacket;
• and
• a connector having a generally cylindrical body open at both ends, engageable at one end with said coupling unit, and at the other end receiving said cable,
• a bushing with a bore to closely receive said cable, mounted within said body proximal said other end thereof, and
• an annular mandrel with a bore to closely receive said core of said cable, housed within said body proximal to said one end thereof, said mandrel having a sleeve engaged with the cable beneath said jacket, contacting said foil, the jacket being stretched to a diameter greater than the internal diameter of the bushing, said sleeve being engageable with said cable by pushing the mandrel and the cable together;
• and wherein by pulling on the cable engaged with the mandrel and by screwing the connector onto the coupling unit, the mandrel is movable longitudinally within said body from a position in which the sleeve is not surrounded by the bushing in which the sleeve may be engaged to the cable, to a position in which the sleeve is at least partially within the bushing in which the jacket frictionally engages the bushing to retain the cable in the connector.
