<p>PROBLEM TO BE SOLVED: To prevent temperature rise of a connector effectively through a simple structure. SOLUTION: A wiring member 14 is housed in a case 12 comprising upper and lower cases 12A, 12B to constitute a joint box J/B 10a. The wiring member 14 is applied, to the back surface thereof, with a thermally conductive member 20 made of a metal excellent in thermal conductivity, e.g. aluminum. The thermally conductive member 20 comprises a planar heat absorber 22 being fixed to the wiring member 14, and a radiator 24 being fixed to the rear of the heat absorber 22 projecting to the outside through an opening 28 made in the lower case 12B. The heat absorber 22 is provided with many fins 26 on the surface at the forward end thereof.</p> |
