Problems solved by technology

In addition, openings in housings made of resin-molded objects are sometimes warped during molding, making it difficult to ensure dimensional accuracy
Therefore, the ability to set only the design value of the size of the gap between the connector and the opening in the housing has been limited, and a new method is required

Embodiment Construction

[0028] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0029] first, figure 1 Shown is a junction box 12 including an ECU unit 10 related to an electrical junction box used as an embodiment of the present invention. The junction box 12 is constituted by mounting the ECU unit 10 to a body unit 13 serving as another electrical junction box.

[0030] figure 2 An ECU unit 10 is shown. The ECU unit 10 is constructed such that in image 3 A printed circuit board 20 serving as a circuit board, shown in figure 1 ) and the lower housing 16 are assembled.

[0031] The printed circuit board 20 is provided with a connector 22 . The connector 22 is made of synthetic resin and has a long block shape. respectively formed in the longitudinal direction of the connector 22 ( image 3 The bolt fixing portions 24 on both ends of the vertical direction in ) are fixed to the printed circuit board 20 by bolts (not shown), wh...

Abstract

Provided is an electrical junction box having a novel structure, said electrical junction box having a connector exposed to the outside of a case through an opening of the case, and being capable of preventing foreign material from entering through a gap between the opening and the connector. A protruding plate section (28) is formed to a connector (22) housed in an opening (36) of a case (18), said protruding plate section extending parallel to a circuit board (20), a cover plate section (42) for covering the protruding plate section (28) is formed on the inner circumferential surface (40a) of the opening (36) of the case (18), said cover plate section being positioned on the opposite side to the circuit board (20) with respect to the protruding plate section (28), and the gap between the connector (22) and the opening (36) of the case (18) is closed by means of the protruding plate section (28) and the cover plate section (42).

Description

technical field [0001] The present invention relates to an electrical junction box for installation in automobiles, etc., and more particularly to an electrical junction box in which a connector provided on a circuit board accommodated in a case passes through the case The opening part in is exposed to the outside. Background technique [0002] Generally, electrical junction boxes have been used in automobiles and the like, for example, in order to efficiently distribute power from a power source such as a battery to electrical components. For example, JP 2008-172889A (Patent Document 1) discloses a known example of such an electrical junction box configured as an ECU (Electronic Control Unit) in which a circuit board is housed in a case, and which can be installed to or separate from another electrical junction box such as a junction box. [0003] With the electrical junction box disclosed in Patent Document 1, a connector provided on a circuit board is exposed to the out...
