Abstract
A transient voltage protector is provided for telephone lines and the like. An insulating plastic housing is provided with two pairs of terminals having female connections at the lower ends for association with selected terminals of a telephone terminal block. The upper ends of these terminals are of a male type and extend above the top of the housing for receipt of further elements such as bridging clips, plug-in fuse units, or line status indicators. An offset and raised portion of the housing carries a pair of zener diodes having lower wire terminals connected to two of the aforesaid terminals. The upper wire terminals of the zener diodes are connected to a grounding terminal having an upper portion extending above the housing in the form of two spaced tines for receipt of a common ground wire between the tines. The various terminals and the zener diodes and the housing have complementary structure for positioning of the terminals and the diodes within the housing. In a modification the housing has a second offset and raised portion mounting two gas diodes.
