Embodiment Construction

[0035] will refer to Figures 1 to 7 A "waterproof box" according to an embodiment of the present invention and an "electrical junction box" including the waterproof box are described. And, an 'electrical junction box' is installed on the vehicle to supply power and transmit signals to electronic devices installed on the vehicle. Also, in the present invention, a junction block (also referred to as a "junction box", a fuse block (also referred to as a "fuse box"), and a relay block (also referred to as a "relay box") are collectively referred to as an electrical junction box.

[0036] Such as figure 1 with 2 As shown, the electrical junction box 10 includes: a waterproof box 1; a box block 5, which is made of synthetic resin and attached to the inside of the waterproof box 1; and a plurality of boxes installed on the box block 5 Electrical parts 11, 12 and 13 (in Figure 4 with 6 shown in ).

[0037] The waterproof case 1 includes: a body cover 3; an upper cover 2 (corr...

Abstract

Provided is a waterproof box capable of increasing the amount of water discharged from a double wall without reducing the rigidity of a body case. A waterproof box (1) is provided with a body case (3) and an upper cover (2) attached to the body case (3) so as to cover an opening (30a) of the body case (3). A peripheral wall (39) of the body case (3) has a double-wall structure including an outer wall (31) and an inner wall (32). Liquid penetrating from a seam between the upper cover (2) and the outer wall (31) passes between the outer wall (31) and the inner wall (32) and is discharged to the outside of the body case (3). A wide width portion (6) and a narrow width portion (7) which have mutually different gaps between the outer wall (31) and the inner wall (32) are formed in the body case (3). Furthermore, the inner wall (32) has connection portions (8) bent outward from the ends of the wide width portion (6) and inward from the ends of the narrow width portion (7).

Description

technical field [0001] The present invention relates to a waterproof box for installation in an electrical junction box or the like on a vehicle. Background technique [0002] Various electronic devices are mounted on the vehicle. In order to supply power and transmit signals to various electronic devices, electrical junction boxes are placed at appropriate locations in the vehicle. The electrical junction box uses a waterproof box to prevent water from intruding into it when driving in rain or washing the car. For example, waterproof boxes have various structures, but generally include: a body cover that accommodates a plurality of electrical components; and a cover that covers an opening of the body cover (see Patent Document 1, for example). and, Figure 8 The figure shows a plan view of a body cover of a waterproof box used in an electrical junction box according to the prior art. [0003] Figure 8 The illustrated body cover 303 is made of synthetic resin, and includ...
