Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a water draining structure for an electric connection box used for wiring in an automobile.

[0002]

[Prior art]

 As shown in FIG. 3, an electric connection box used for wiring in a vehicle has a structure in which a cover 10 is covered on a box 9, and electric parts such as relays and fuses are mounted on a base 12 fixedly installed in the box 9. 13 are attached, and to each of these electric parts 13, a wire harness 14 drawn through the grommet 3 on the side of the box 9 is connected. Further, in such an electric connection box 1, water may enter from the boundary between the box 9 and the cover 10 or when the cover 10 is opened. The drain hole 4 is opened.

[0003]

[Problems to be solved by the device]

 However, such an electric connection box with a drain hole is said to cause a trouble when water is forced into the drain hole during vehicle washing or while running on a submersible to wet the electrical components inside. There was a problem.

[0004]

[Means for Solving the Problems]

 The present invention provides a water draining structure for an electrical junction box, which solves the above-mentioned problems. The configuration is such that two bottom plates having drain holes are provided at the bottom of the electrical junction box. The feature is that the positions of the water drain holes of the plate are horizontally shifted.

In the present invention, the two bottom plates at the bottom of the electrical junction box are provided with a slope of downward slope toward the drainage holes so that the inundation can be easily discharged. Further, it is preferable to provide a shielding plate between the drainage holes of the two bottom plates to more reliably prevent water from entering through the drainage holes of the outer bottom plate.

[0006]

[Action]

 The water drainage structure of the electric junction box of the present invention is such that two bottom plates having water drainage holes are arranged by horizontally shifting the positions of the water drainage holes. Even if the water vigorously hits the bottom plate and the water passes through the outer drainage holes, it will not be blocked by the inner bottom plate and the water will not splash on the electrical components. In addition, when the cover is opened, water and the like are discharged through the water drain holes of the two bottom plates in order.

【Example】

 Hereinafter, the present invention will be described in detail with reference to examples. Embodiment 1 FIGS. 1A and 1B are a side sectional view and a perspective view of an inner bottom plate, respectively, showing an embodiment of a drainage structure of the present invention. This electric junction box 1 is provided with another bottom plate 2 inside the conventional electric junction box, and this inner bottom plate 2 is attached with an inclination so that the grommet 3 side becomes higher. Has a drain hole 4 at the bottom center. The outer bottom plate 5 has a drain hole 4 at a predetermined position near the grommet 3, and the outer bottom plate 5 has a downward slope toward the drain hole 4. Further, a shield frame 6 is attached to the lower side of the inner bottom plate 2 so as to prevent water from entering more reliably. The height of the front and rear feet of the shielding frame 6 is changed, and the inner bottom plate 2 is inclinedly arranged only by placing it on the outer bottom plate 5.

Embodiment 2 FIGS. 2A and 2B are respectively a disassembled perspective view and a side sectional view after assembly showing another embodiment of the water draining structure of the present invention. In this drainage structure, a shielding plate 7 is provided at the center of the bottom surface of an electrical connection box having a conventional drainage hole 4, and a box-shaped bottom plate 8 is provided below the electrical connection box 21 provided with the shielding plate 7. It is attached. This drainage structure is simple in that there is no need to tamper with the inside of the electric junction box by providing the shield plate 7 on the bottom surface of the conventional electric junction box and attaching the simple stoppers 9 on the side surfaces. When the above two types of electrical junction boxes were washed, no water was found inside the electrical junction boxes. The shielding frame or the shielding plate provided in the above-mentioned embodiment is not always necessary, and even if it is not provided, almost sufficient prevention of water infiltration is achieved.

[0009]

【effect】

 As described above, the water draining structure of the electric connection box of the present invention can reliably prevent water from being inundated when washing the vehicle, so that electrical equipment will not be submerged and cause a failure.
