Coaxial connector for soldering to semirigid cable

An improved coaxial connector of the type having an outer conductive shell in which is contained a dielectric sleeve containing an inner contact, and having a rearward end adapted to be terminated to an end of a coaxial cable having a semirigid outer conductor around an insulative jacket containing an inner conductor having an end thereof extending beyond an end face of said cable to be matably received by a complementary rearward contact section of said inner contact, the improvement comprising:

• a retention sleeve insertable over said rearward section of said outer conductive shell from a rearward end thereof, said retention sleeve having a body section having an inner diameter incrementally smaller than an outer diameter of said rearward section of said outer conductive shell;
• said retention sleeve including an inwardly directed annular flange at a rearward end thereof engageable with said rearward end of said rearward section of said outer conductive shell;
• said rearward section of said outer conductive shell including a cable-receiving bore extending thereinto from said rearward end, said cable-receiving bore and said inwardly directed annular flange of said retention sleeve having respective inner diameters just larger than the outer diameter of said semirigid outer conductor of said cable;
• said cable-receiving bore including an annular recess formed thereinto from said rearward end, and
• an annular preform of solder being disposed in said annular recess and held therein by said inwardly directed annular flange of said retention sleeve,
• whereby said connector includes a preform of solder contained therein enabling the outer conductive shell of the connector to be soldered to the semirigid outer conductor of the cable.

An improved coaxial connector of the type having an outer conductive shell in which is contained a dielectric sleeve containing an inner contact, and having a rearward end adapted to be terminated to an end of a coaxial cable having a semirigid outer conductor around an insulative jacket containing an inner conductor having an end section extending forwardly from the cable end to be matably received by a complementary rearward contact section of said inner contact, the improvement comprising:

• a retention sleeve insertable over said rearward section of said outer conductive shell from a rearward end thereof, said retention sleeve having a body section having an inner diameter incrementally smaller than an outer diameter of said rearward section of said outer conductive shell;
• said retention sleeve including an inwardly directed annular flange at a rearward end thereof engageable with said rearward end of said rearward section of said outer conductive shell;
• said rearward section of said outer conductive shell including a cable-receiving bore extending thereinto from said rearward end, said cable-receiving bore and said inwardly directed annular flange of said retention sleeve having respective inner diameters just larger than the outer diameter of said semirigid outer conductor of said cable;
• said cable-receiving bore including an annular recess formed thereinto from said rearward end;
• an annular preform of solder being disposed in said annular recess and held therein by said inwardly directed annular flange of said retention sleeve;
• and
• said body section of said retention sleeve comprising a first layer of a first metal having low electrical resistance and low magnetic permeability and having defined on the outwardly facing surface thereof a second layer of a second metal having high electrical resistance and high magnetic permeability intimately joined to said first layer,
• whereby said connector includes a preform of solder contained therein and defining a self-regulating temperature source adapted to reflow the solder preform upon being subjected to constant amplitude high frequency alternating current, forming a solder joint between said semirigid outer conductor and at least one of said retention sleeve and said outer conductive shell, enabling the outer conductive shell of the connector to be electrically joined to the semirigid outer conductor of the cable.
