ABSTRACT:
A protective structure for a surge absorber which is composed of the surge absorber, connecting means for connecting the surge absorber to an electronic device and means for protecting the surge absorber as well as the electronic device from fire caused by a continuous overvoltage. The surge absorber protecting means is composed of a first electroconductive spring member which does not deteriorate from heat generated by repeated transient surge voltages to which it might be subjected. This spring member may be connected to a communication line and is movable between a first spring-loaded position wherein it connects the electronic device and the surge absorber to the communication line and a second non-spring loaded condition wherein the connection is broken. Also included are release means for releasing the first member from its first spring-loaded position which release means is activated by heat generated from a continuous overvoltage.
