Abstract:
1. A coaxial switching jack comprising: a housing defining an interior and an exterior, the housing including a pair of front cable connection locations and a pair of rear cable connection locations, each front cable connecting location configured to receive a mating coaxial cable connector; a pair of coaxial assemblies mounted within the interior of the housing, each coaxial assembly having a first end adjacent one of the front cable connection locations and a second end adjacent one of the rear cable connection locations, each coaxial assembly including a center conductor and an outer shell conductor, the outer shell conductor of each coaxial assembly including a generally cylindrical wall and an opening formed in the cylindrical wall, wherein the center conductors of the coaxial assemblies are electrically connected to each other by conductive elements extending through the openings in the cylindrical walls of the outer shell conductors and the outer shell conductors of the coaxial assemblies are also electrically connected to each other; a resistor assembly mounted within the interior of the housing, the resistance level of the resistor assembly being changeable from the exterior of the housing; wherein insertion of the mating coaxial cable connector into one of the front cable connection locations electrically isolates the center conductors of the coaxial assemblies from each other and also electrically isolates the outer shell conductors of the coaxial assemblies from each other; wherein insertion of the mating coaxial cable connector into one of the front cable connection locations electrically connects a center conductor of the mating coaxial cable connector with the center conductor of the corresponding coaxial assembly and electrically connects an outer shell conductor of the mating coaxial cable connector with the outer shell conductor of the corresponding coaxial assembly; wherein once the mating coaxial cable connector is inserted into one of the front cable connection locations, the outer shell conductor of the mating coaxial cable connector closes the opening on the cylindrical wall of the outer shell conductor of the corresponding coaxial assembly to form a generally cylindrical conductive passage about the center conductors of the mating coaxial cable connector and of the corresponding coaxial assembly, the cylindrical passage extending from the first end of the corresponding coaxial assembly to the second end of the corresponding coaxial assembly; and wherein once the mating coaxial cable connector is inserted into one of the front cable connection locations to engage the corresponding coaxial assembly, the center conductor of the non-mated coaxial assembly is electrically connected to the outer shell conductor of the non-mated coaxial assembly through the resistor assembly, wherein the impedance level between the center conductor and the outer shell conductor of the non-mated coaxial assembly can be changed through the resistor assembly from the exterior of the housing.
