Abstract
A communication circuit protector is provided for use with connector blocks in telecommunication equipment. The circuit protector includes a uniquely-designed two-piece interfitting housing for accommodating a variety of protector circuits to provide different kinds of over-voltage and/or overcurrent protection while using the same housing. The housing is adapted to plug-in or to be inserted into the connector clips of a Krone-style terminal block. The side of the housing is provided with means for retaining a side ground contact which is connectible to one of the grounding tab members of the grounding bar of the connector block. In a preferred embodiment, the protector circuit includes a diode bridge rectifier, a pair of voltage suppressors, and a pair of sneak current fuses.
Claims20
A circuit protector for protecting equipment against overvoltage and overcurrent conditions, comprising:
- a housing comprising an upper body portion and a lower body portion;
- voltage limiting means and current limiting means for disposition within said upper body portion of said housing for protecting equipment against overvoltage and overcurrent conditions, respectively;
- first contact means for disposition within said housing for establishing electrical contact with said current limiting means and said voltage limiting means when overvoltage and overcurrent protection is to be provided in connection with said equipment, and for establishing electrical contact with said current limiting means when only overcurrent protection is to be provided in connection with said equipment;
- and
- second contact means for disposition within said housing for establishing electrical contact with said voltage limiting means when only overvoltage protection is to be provided in connection with said equipment.
