Embodiment Construction

[0025] based on Figure 1 to Figure 6 The waterproof structure of the electric connection box which concerns on one Embodiment of this invention is demonstrated. figure 1 The electrical junction box 1 shown in FIG.

[0026] In the following, for the sake of illustration, use figure 1 Each part is described in the directions of up, down, left, right, front, back, and back. Such as figure 1 As shown, the electric junction box 1 has a main body case 2 and a cover 4 which are integrally molded from an insulating synthetic resin.

[0027] Such as Figure 1 to Figure 3 As shown, the above-mentioned main body casing 2 has a peripheral wall 25 formed by arranging a front wall portion 21, a left wall portion 22, a rear wall portion 23 and a right wall portion 24 in a rectangular shape in plan view. Connectors 26 , 27 , and 28 are provided on the front wall portion 21 , the rear wall portion 23 , and the right wall portion 24 , respectively. In addition, a circuit board 29 elec...

Abstract

Provided is a waterproof structure of an electric junction box which can enhance waterproof performance by preventing penetration of water droplets or the like from a punching hole into a body case in the structure of an electric junction box having a step portion which requires to form a punching hole for forming a latching protrusion on the circumferential wall of the body case. An extension (37d), for moving the position of a punching hole (37) which is required to be formed in a step portion (35) to the side of a latching protrusion (33), is formed on the left wall portion (22) of a body case (2), and a hole sealing portion (47a) entirely covering the opening of the punching hole (37) moved to the side of the latching protrusion (33) is formed at the edge (42a) of the left wall portion (42) of a cover (4) under a state where the cover (4) is fixed to the body case (2).

Description

technical field [0001] The present invention relates to a waterproof structure of an electrical junction box mounted in an engine room of a motor vehicle or the like. Background technique [0002] An electrical junction box for supplying electric power from a battery to various electrical components is installed in an engine room or the like of a motor vehicle. The electrical junction box has a plurality of connectors, and includes a main body case and a cover that house circuit boards connected to the connectors and are each integrally formed of resin. [0003] In the above electrical junction box, a locking protrusion is protruded from one outer surface of the body case or the cover, and an engaging protrusion is protruded from the other inner surface. By engaging the locking protrusion and the engaging The cover is attached to the main body case by protruding to protect the circuit board housed in the electrical junction box from external water drops and dust (see, for e...
