Abstract
Protection system for telephone terminal strips and the like. The system is based on fitting a conductor bridge 3 between the earthing bars 2 situated longitudinally along the sides of a terminal strip 1 used in telephone exchanges, which is equipped with different levels of pairs between the aforementioned earth bars 2. The bridge 3 is formed by two conducting plates 4 and 5 joined at their ends, extending into elastic end plates 6 by means of which the electrical and mechanical connection is made with the earth bars 2, enabling separate protection modules for each pair to be fitted between the plates 4 and 5 of each bridge 3, allowing their individual removal for carrying out any kind of operation, keeping the remaining pairs of this level in operation. Each protection module 9 includes a tripolar gas discharger 12 with its socket outlets 14 and an elastic conducting plate 15 around the electrode, rounded off at the ends 16 that emerge through the sides of the module itself 9 to make contact with the two plates 4 and 5 of the bridge 3 and thus create the corresponding earth connection.
