Abstract

PURPOSE: To facilitate the wiring operation, to prevent the malfunction of a relay and to eliminate the thermal deterioration of the conductor insulating coating of a conductive wire by electrically connecting a thermocouple, which is arranged at a portion of a high temperature to be detected, and the relay, which is arranged at a remote position, through the preset wire.
CONSTITUTION: A thermocouple 1, which is arranged at the high temperature portion of an exhaust system to be detected, is connected through a conductive wire 3 with a current relay 2 which is arranged at a remote position. The wire 3 is composed of twisted lead wires 4 and 5 which are coated with a bottomless woven member 6 of stainless wires having magneticism. The lead wires 4 and 5 themselves insulate and cover the non-twisted bundle of copper filaments. The terminal ends of the lead wires 4 and 5 are fused at the thermocouple wire elements 7 and 8 and junctions 9 and 10. The woven member 6 has its outer periphery fitted through a cushioning layer 11 in a sleeve 12 which is formed on the outer periphery of the container of the thermocouple at the side of the connecting end. The thermocuple is fastened by means of a nut 13.
