  • Patent number: 6431915
    Abstract: A radio frequency transmitting system comprises first and second cable connector assemblies. The first cable connector assembly includes a first plug connector (8) having a spacer (1) mounted therearound, and a first receptacle connector (22). The first receptacle connector has a ground shell (24), and two tabs (26) depending from opposite sides of the ground shell. The second cable connector assembly includes a second plug connector mechanically identical to the first plug connector, and a second receptacle connector (16). The second receptacle connector is mechanically identical to the first receptacle connector except that two tabs (20) depending from opposite sides of a ground shell (18) of the second receptacle connector depend further than the tabs of the first receptacle connector. Therefore the second receptacle connector cannot be electrically engaged with the first plug connector, due to interference between the tabs of the second receptacle connector and the spacer.
