Abstract

To provide a waterproof structure of an electric junction box wherein a waterproof property can be enhanced by a simple construction. The body 20 of an electric junction box 10 is provided with external double walls 24a and 24 so that fitting edges 32a of covering members 30f and 30r positioned on the front side and the rear side of the electric junction box 10 are covered therewith. The external double walls 24a and 24 are so provided that the covering members 30f and 30r are contained therein. Thus, moisture that dropped on the front side of the electric junction box 10 flows outside the covering members 30f and 30r, and the moisture is prevented from entering the electric junction box 10. Even if moisture flows to the body 20 side along the covering members 30f and 30r, and enters the external double walls 24a and 24, the ingress of the moisture into the electric junction box 10 is prevented by the inner wall of the external double walls 24a and 24 provided on the body 20. Therefore, a waterproof effect is enhanced. (C)2004,JPO&NCIPI.

Description

technical field

[0001] The present invention relates to a waterproof structure of an electrical junction box. Background technique

[0002] Generally, the electrical junction box used in the electric circuit of the automobile is installed in the engine room in many cases, but it is also sometimes installed in the vehicle.

[0003] At this time, there is little direct contact with water, but in the case of wet cleaning (washing) in the car that has been practiced in recent years, when drinking and drinking in the car are spilled, and when condensation occurs in the air-conditioning pipe, etc. , It is also required to prevent water from entering the car.

[0004] For the problems referred to above, as shown in Figure 6, the official publication No. 55-129479 (refer to page 1, figure 1 ) discloses an example of an electrical junction box 100 composed of a main body 101 and a cover member 102 and forms a waterproof structure 103 that prevents water from entering between the ma...
