Abstract
A protector module for use in mounting a gas tube arrester or carbon arrester assembly in a telephone central office protection system has an insulating base and a conductive case or cover. The base has a channel with a projecting stop on one side, in which channel is disposed a portion of a line contact. Another portion of the line contact extends through the base and is positioned against an upstanding wall located at one end on the other side of the base, in which side the gas tube arrester or carbon arrester assembly is disposed. The case is secured about the other side and the upstanding wall by a plurality of spherical projections on the base which lodge in holes in the case. When the case is so positioned on the base, a line electrode of the gas tube arrester or carbon arrester assembly makes electrical contact with the line contact and a ground electrode of the gas tube arrester or carbon arrester assembly is coupled to the case.
