Abstract: A coaxial cable assembly 2 consists of a plug coaxial connector subassembly 4 and a jack coaxial connector subassembly 6. A plug connector 10 and a jack connector 50 are respectively mounted in molded plug and jack housings 20 and 60 respectively. The plug and jack housings 20 and 60 include a latching beam 66 that is attachable to a raised bum 26 on the other connector. The maximum force for disengaging the two subassemblies is greater than the engagement force because the bump includes a sloping forward surface 36 and a steep rear surface 38. When used with connectors 10 and 50 that have equal mating and unmating forces, the total unmating force exceeds the mating force. The latches and the connectors are also positioned so that maximum mating forces of the two separate latching systems do not overlap, thus keeping the total mating force within acceptable limits.
