Embodiment Construction

[0048] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0049] figure 1 It is a front view of the board|substrate storage box 1 of this embodiment, figure 2 is to mean along figure 1 Diagram of a section of a section of line II-II.

[0050] The board storage box 1 is arranged, for example, in an engine compartment of a vehicle, etc., and houses a circuit board 11 used for lamp body control and the like inside. The board|substrate storage box 1 is equipped with the circuit board 11 on which the electrical component 10 was mounted, the base 12 which fixed the circuit board 11, and the case cover 13 which covers the outer side of the circuit board 11. Main parts of the base 12 and the case cover 13 are formed of a resin material.

[0051] It should be noted that, in the following, for the convenience of explanation, the figure 1 The up and down direction of is referred to as the up and down direction for the substrate sto...

Abstract

To provide a board storage box capable of preventing water droplets from adhering to a circuit board without complicating the structure of the base. The substrate storage box includes a circuit substrate, a base, and a case cover. The circuit board mounts electrical components. Fix the circuit board on the base. The case cover covers the outside of the circuit board, and the lower edge of the case cover is fitted into the outer surface of the base. The base has a substrate installation portion, a water catch groove, and an outer side wall. The circuit board is installed in the board installation part. The water catch groove is recessed downward at a position outside the substrate installation part, and the bottom surface extends obliquely downward. The outer wall extends above the bottom surface of the water catching groove on the outside of the water catching groove, and is arranged to face the inner surface of the side wall of the tank cover.

Description

technical field [0001] The present invention relates to a substrate storage box for accommodating circuit substrates therein. Background technique [0002] A circuit board on which electrical components are mounted is arranged in an engine room of a vehicle, inside an instrument panel, or the like. In order to avoid adhesion of water droplets, dust, etc., circuit boards are sometimes stored in a board storage box and used (for example, refer to Patent Document 1). [0003] The substrate storage box described in Patent Document 1 includes a base on which a circuit substrate is fixed, and a case cover that covers the outside of the circuit substrate. The lower edge of the box cover is fitted to the outer surface of the base. A groove is formed on the outer surface of the base, and the groove extends substantially horizontally so that the opening side faces the inner surface of the side wall of the case. A sufficient separation width is ensured between the upper opening edge...
