<p>PURPOSE:To prevent looseness of a bus-bar wiring board inside an electrical junction box and then a failure caused by it by bringing the surface at the connection side of the electronic circuit unit into press contact with the outer surface of a main cover. CONSTITUTION:The title structure is a joint one between an electrical junction box 1' housing a bus-bar wiring board 5 between a main cover 3 and an under cover 4 and an electronic circuit unit 2 incorporating a functional circuit. Then, a boss 20 for clamping is provided in one piece on the inner surface (upper surface) of the under cover 4 instead of providing the boss for clamping at the main cover 3. Further, the boss 20 for clamping is allowed to protrude from the upper surface of the main cover 3 via through holes 21 and 22 which are formed on the bus-bar wiring board 5 and the main cover 3, respectively. With this kind of structure, the looseness of the bus-bar wiring board 5 inside the electrical junction box 1' is eliminated and wear due to sliding for the connection part of connectors can be avoided.</p> |
