CONNECTING STRUCTURE FOR INTERNAL CIRCUIT OF JUNCTION BOX TO RELAY

摘要

PROBLEM TO BE SOLVED: To provide a relay connecting structure capable of reducing the number of layers of bus bars in a junction box. SOLUTION: Bus bars for base circuit provided in the junction box and bus bars for relay connection are separated from each other. There is provided a relay module on which the bus bars for relay connection are fixed on the backside of an insulating plate. The relay module is pierced with a through-hole communicating with the bus bars for relay connection and the insulating plate. A relay is mounted on the surface of the insulating plate, the terminal of the relay is passed through the through-hole, and front ends protruding from the hole for the bas bars for relay connection are fixed with lead-less soldering. The front ends of the bus bars for relay connection are formed so as to protrude from the insulating plate. The front ends of the bus bars for relay connection of the relay module are formed so as to be welded to the bus bars of the base circuit.
