Abstract
Abstract A tap connector assembly (210) for coaxial cable networks includes a receptacle tap connector (206) incorporated into the cable network and a plug connector (208) mateable therewith to connect external apparatus into the network. Contacts (219, 322, 323) are adapted to be engaged by terminals (386, 387, 388) in plug connector (208) when plug connector (208) is mated with receptacle tap connector (206) to connect external apparatus into the network. Receptacle tap connector (206) includes normally closed switch means (340) for providing a first signal path between signal carrying contacts (322, 323) when the receptacle tap connector is not in use, and the plug connector (208) includes cam surfaces (405, 406) for opening normally close switch means (340) when the connectors are mated to interrupt the first signal path. The tap connector (206) includes means for defining first and second substantially radially extending, sheath engaging surfaces (253, 293, 294) for clamping an exposed, fanned out portion of conductive sheath (22) therebetween for electrically connecting the conductive sheath to the grounding contact (219).

Claim 1
Independent Claim
307 words
A tap connector for coaxial cable networks, comprising: a connector housing; first and second signal carrying contacts carried by said connector housing and adapted to be electrically connected to first and second conductors, respectively; normally closed switch means for electrically connecting said first and second signal carrying contacts for providing a first signal path between said first and second signal carrying contacts, said normally closed switch means including a movable switch arm attached to each of said first and second signal carrying contacts and adapted to normally engage the other of said signal carrying contacts for normally providing said first signal path between said first and second signal carrying contacts; a third grounding contact carried by said housing and adapted to be connected to conductive sheaths of one or both of said first and second conductors; and receiving means on said housing for receiving a mating connector, whereby said first, second and third contacts are engaged by terminals on said mating connector when said mating connector is received by said receiving means for providing electrical connection of said first and second signal carrying contacts and of said third grounding contact with said terminals on said mating connector, and for establishing a second signal path between said first and second signal carrying contacts through said mating connector, said movable switch arms being adapted to be displaced from the other of said signal carrying contacts in a direction generally parallel to the direction of movement of said mating connector by cam surfaces on said mating connector during mating of said mating connector with said tap connector to open said normally closed switch means for interrupting said first signal path whereby only said second signal path through said mating connector is provided between said first and second signal carrying contacts when said mating connector is received by said receiving means.
Claim 2
Dependent Claim
307 words
A tap connector for coaxial cable networks, comprising: a connector housing; first and second signal carrying contacts carried by said connector housing and adapted to be electrically connected to first and second conductors, respectively; normally closed switch means for electrically connecting said first and second signal carrying contacts for providing a first signal path between said first and second signal carrying contacts, said normally closed switch means including a movable switch arm attached to each of said first and second signal carrying contacts and adapted to normally engage the other of said signal carrying contacts for normally providing said first signal path between said first and second signal carrying contacts; a third grounding contact carried by said housing and adapted to be connected to conductive sheaths of one or both of said first and second conductors; and receiving means on said housing for receiving a mating connector, whereby said first, second and third contacts are engaged by terminals on said mating connector when said mating connector is received by said receiving means for providing electrical connection of said first and second signal carrying contacts and of said third grounding contact with said terminals on said mating connector, and for establishing a second signal path between said first and second signal carrying contacts through said mating connector, said movable switch arms being adapted to be displaced from the other of said signal carrying contacts in a direction generally parallel to the direction of movement of said mating connector by cam surfaces on said mating connector during mating of said mating connector with said tap connector to open said normally closed switch means for interrupting said first signal path whereby only said second signal path through said mating connector is provided between said first and second signal carrying contacts when said mating connector is received by said receiving means.
