Abstract
Abstract A tap connector assembly (10) for coaxial cable networks includes a receptacle tap connector (6) incorporated into the cable network and a plug connector (8) mateable therewith to connect external apparatus into the network. Receptacle tap connector (6) includes first and second signal-carrying contacts (122, 123) and a grounding contact (19) adapted to be connected to signal-carrying conductors (24) and conductive outer sheaths (222) of first and second cables (12a,12b), respectively, in the network. Contacts (19, 122, 123) are adapted to be engaged by terminals (186, 187, 188) in plug connector (8) when plug connector (8) is mated with receptacle tap connector (6) to connect external apparatus into the network. Receptacle tap connector (6) includes normally closed switch means (140) for providing a first signal path between signal-carrying contacts (122, 123) when the receptacle tap connector is not in use, and plug connector (8) includes a cam surface (205) for opening normally closed switch means (140) when the connectors are mated to interrupt the first signal path whereby only a second signal path is established between signal-carrying contacts (122, 123) through the plug connector to connect the external apparatus into the network in series and to ensure that the integrity of the cable network is maintained at all times.
