<p>PROBLEM TO BE SOLVED: To suppress the deformation of an electrical junction box and enable the stable electrical connection by a method wherein bearing surfaces are provided on one of a board housing unit and a wiring board at positions corresponding to the positions of a bracket to which an external force is applied so as to be pressed against the other and, when the external force is applied to the bracket in a direction toward the inside of the box, the bearing surfaces are pressed against the wiring board or the board housing. SOLUTION: Bearing surfaces 20 which are pressed against a wiring board 5 are provided on a board housing unit 2 at positions corresponding to the positions of the bracket 6 of an electrical junction box 1 to which an external force is applied. The bearing surfaces 20 comprises two protruding strips and are formed integrally on the bottom 2b of the board housing unit 2 with heights approximately the same as the spacing between the bottom 2b and the wiring board 5 so as not to interfere wires 4 on the wiring board 5. With this constitution, even if the external force F1 is applied to the flange part 6a of the bracket 6 of the electrical junction box 1 in a direction toward the inside of the box, the force is distributed by the bearing surfaces 20 before it is transmitted to the wiring board 5, so that the deformation of the box can be suppressed and hence the deformation of the wiring board 5 can be avoided and the stable electrical connection can be realized.</p> |
