  • Method for applying a retention sleeve to a coaxial cable connector
    Patent number: 5269701
    Abstract: A coaxial connector (100) having a coupling nut (12) freely rotatable therearound has a rear stop defined by the forward end (152) of a retention sleeve (150) placed along the central section (128) of the outer conductive shell (120). The retention sleeve rearward end (160) defines a forward stop for a crimping ferrule (196) placed over the reduced diameter rearward shell section (134) and trapping an end of a shielding braid (184) therebetween to be crimped. The retention sleeve includes a rearward section (156) having an inner diameter incrementally less than the outer diameter of the central section (128) of the outer conductive shell so that the retention sleeve (150) is force fittable thereonto and self-retains thereon.
    Type: Grant

  • Coaxial connector for soldering to semirigid cable
    Patent number: 5232377
    Abstract: A retention sleeve (150) is placed over the rearward end (134) of the outer conductive shell (120) of a coaxial plug connector (100), providing a rearward stop for retaining the coupling nut (12) on the shell. The retention sleeve can include an inwardly directed flange (158) at its rearward end for retention of an annular solder preform (132) within the cable-receiving bore (136) of the outer conductive shell. The retention sleeve (150) can be of low resistance copper having a thin outer layer (170) of magnetic high resistance metal, defining a self-regulating temperature source when subjected to RF current, to reflow the solder of the preform (132) and thus solder the outer conductive shell (120) to the semirigid outer conductor (82) of the coaxial cable end inserted into the cable-receiving bore (136) providing for automated soldering.
