Abstract
A self-terminating network of stations connected by coaxial cable segments with each cable segment having ends with cable connectors for coupling to matching device connecters. Each connector has a switchable termination circuit de-activated by coupling to a matching connector. An uncoupled connector will serve as a terminator. The device connector can be a tap connector for mounting on a printed circuit board, for minimizing the length of the tap, and reducing the distrubance to an attached coaxial cable network.
Claims4
A self-terminating tap connector adapted for mounting on a printed circuit board, comprising:
- first and second coaxial connector ports with connected center conductors and connected shields;
- a center tap connected to said connected center conductors and extending through and ending external of said connected shields;
- mounting tabs on said connected shields for attaching said tap connector to a printed circuit board;
- first and second movable electrical contacts within said first and second coaxial connector ports, for contacting to each of said center conductors;
- a sliding dielectric element within each of first and second coaxial connector ports, said sliding dielectric element moved by an inserted mating connector for disconnecting a corresponding said movable electrical contact from contacting a respective said center conductor;
- and
- termination circuit element electrically connected to said movable electrical contacts for switchable termination of said center conductors through said termination circuit element to said connected shields,
- whereby coupling of an inserted mating connector moves said sliding dielectric to disconnect said movable electrical contact from contacting a respective said center conductor, disconnecting said termination circuit element from said center conductor.

- a center tap connected to said connected center conductors and extending through and ending external of said connected shields;
- mounting tabs on said connected shields for attaching said tap connector to a printed circuit board;
- first and second commonly connected contact lands within said connected shields;
- first and second movable electrical contacts within said first and second coaxial connector ports, for contacting from said shields to said first and second commonly connected contact lands;
- and
- a termination circuit element electrically connected from said first and second commonly connected contact lands to said connected center conductors;
- whereby coupling of an inserted mating connector moves a said movable electrical contact to disconnect said movable electrical contact from contacting said shield to said contact land, thereby disconnecting said termination circuit element from said shield.
