Abstract
To provide for closed loop conditions in vacant module positions, as in back panel systems in telecommunications systems, a bridging contact is provided which, in the absence of a module, contacts at least two terminals or contact members. The bridging contact is mounted in the shroud of a back panel. Insertion of a module moves the bridging contact away from contact members. The contact member is given a particular form or shape so that the module does not touch those parts of the bridging contact which actually contact the contact members, giving long serviceability and avoiding damage to the contacting areas.
Claims8
Apparatus for providing closed loop conditions in a vacant module position, comprising:
- a housing forming a shroud for a back panel and including a base portion, a first wall extending at one side of said base portion and normal thereto, and a further wall extending from said base portion and spaced from and parallel to said first wall;
- a plurality of terminals extending through said base portion, said terminals positioned between said walls and including portions extending external to said shroud, in a direction opposite to said walls, for insertion through said back panel for attachment of conductors thereto;
- and
- a spring contact member mounted on said first wall and moveable from a first position to a second position, said contact member in said first position in electrical contact with at least two of said terminals and in said second position deflected away from said terminals on insertion of a circuit module into said housing over said terminals, said spring contact member in said first position on absence of said circuit module.
