BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is an exploded perspective view illustrating a wiring lead-out structure of a waterproof housing according to an embodiment of the present invention. The waterproof housing 50 includes a housing cover 1 and a housing body 2 that is screwed to the housing cover 1 with screws 13. The housing cover 1 has a screw hole 20 through which the screw 13 penetrates, wiring outlets 3 and 4 for extracting wiring cables 7 and 8 described below from the inside of the waterproof housing 50 to the outside, and a tip of the wiring outlet 4. There is provided a convex portion 21 which has a slanted shape at both ends and is joined in combination with the housing body 2.
[0009]
The housing body 2 has a mounting hole 23 for screwing and mounting the housing cover 1 with the screw 13, wiring outlets 3 and 4, and the wiring outlet 4 at the lowermost portion, and both ends are inclined. A concave portion 22 that is combined and joined in correspondence with the convex portion 21 of the housing cover 1, and is provided on a combination surface (joining surface) with the housing cover 1 along the front end surface of the opening side of the housing main body 2. A fixing member 28 for accommodating and fixing the packing 29 and the electronic components 5 and 6 described later is provided.
[0010]
The screw holes 20 are provided at the four corners of the housing cover 1, and the mounting holes 23 are provided at the four corners of the housing body 2 correspondingly. The fixing members 28 are also provided at four corners of the bottom inside the housing body 2 corresponding to the electronic components 5 and 6 described later. With these screws 13, the housing cover 1 is screwed to the housing main body 2. At this time, the packing 29 provided on the housing main body 2 is sandwiched and fitted between the housing cover 1 and the housing main body 2 to ensure waterproofness and water tightness. In addition, when screwed, the wiring cables 7, 8 described below are sandwiched between the wiring covers 3, 4 of the housing cover 1 and the housing main body 2 and fitted together, thereby also providing waterproofness and water tightness. Is secured.
[0011]
FIG. 2 is an exploded perspective view for explaining a case where electronic components are mounted on the waterproof housing of FIG. 1. FIG. 3 is a side view of the waterproof housing and the electronic components of FIG. is there. In FIG. 2, one end of a wiring cable 7 is attached to a predetermined location on the electronic component 5, and one end of a wiring cable 8 is attached to a predetermined location on the electronic component 6. These electronic components 5 and 6 are attached and fixed to fixing members 28 by screws 24 using respective screw holes 25 and 27 provided at four corners and a connecting member 26 connecting the electronic components 5 and 6. . Then, as described above, the housing cover 1 is screwed to the housing main body 2 by the screw 13, and the wiring cables 7, 8 are moved between the housing cover 1 and the wiring outlets 3, 4 of the housing main body 2. It is sandwiched and joined. In this case, as shown in FIG. 3, the inclined portions 9 and 10 of the housing cover 1 and the inclined portions 11 and 12 of the housing body 2 are combined and joined.
[0012]
Thus, when the electronic components 5 and 6 are mounted on the waterproof housing 50, the wiring outlet 3 is used for the wiring cable 7 of the electronic component 5 and the wiring outlet 4 is used for the wiring cable 8 of the electronic component 6. Is used. As shown in FIG. 3, the inclined portion 11 of the housing body 2 corresponding to the inclined portion 9 of the housing cover 1 and the inclined portion 12 of the housing body 2 corresponding to the inclined portion 10 of the housing cover 1. , The combination surface (joining surface) is inclined. That is, as shown in FIGS. 1 to 3, the wiring outlets 3 and 4 are located at different positions in the height direction of the waterproof housing 50 (the direction in which the housing cover 1 is provided in the housing main body 2). By providing an offset so as to be as described above, the combination surface can be inclined. This makes it possible to arbitrarily determine the position of the lead wiring cable and the number of lead wiring cables of the electronic component.
[0013]
FIG. 4 is a diagram for explaining the force applied to the combined inclined portion at the wiring outlet of the waterproof housing. As shown in FIG. 4, the housing cover 1 is screwed to the housing main body 2, and the housing covers 1 and the housing main body 2 are combined and joined in a state where the wiring cables 7 and 8 are pulled out. Is done. In this case, the pressure applied to the combination inclined portion 14 in the housing cover 1 and the housing body 2 is a pressure 15 due to the tightening of the screw 13, and this pressure 15 is combined with the pressure 16 in the horizontal direction and the combination inclination portion 14. The pressure is divided into the inclined portion 14 and the pressure 17 that sandwiches the vertical packing 29. The pressure 17 provides a waterproof effect of the packing.
[0014]
As described above, if the pressure 17 necessary for obtaining the waterproof effect in the combination inclined portion 14 can be obtained, the shape of the offset provided between the wiring outlets 3 and 4 can be arbitrarily determined. For example, as shown in FIG. 5A, the shape of the combination inclined portion 18 may be linearly inclined, or as shown in FIG. 5B, the shape of the combination inclined portion 19 may be curved. it can. In any case, it is assumed that the pressure necessary to obtain a waterproof effect in conformity with a predetermined waterproof standard is applied in a direction perpendicular to the combination inclined portions 18 and 19 and in a direction sandwiching the packing 29. The shape of the offset provided between the wiring outlets 3 and 4 may be any shape as long as the pressure can be obtained.
[0015]
Although the embodiments have been described above, the present invention is not limited to the above-described embodiments, and various modifications and applications are possible within the scope of the claims. For example, in the above-described embodiment, two wiring outlets 3 and 4 are used, but the number of wiring outlets of the present invention is not limited to two, and three or more wiring outlets may be used. Further, in the above-described embodiment, the wiring outlets 3 and 4 are configured to be provided in both the housing cover 1 and the housing main body 2. However, only one of the housing cover 1 and the housing main body 2 is provided. You may comprise so that it may be provided. In the above-described embodiment, the wiring outlets 3 and 4 are provided at different positions with respect to the height direction of the waterproof casing 50. However, the height direction (vertical direction) and the lateral direction (horizontal direction) are provided. Each may be provided at a different position.
[0016]
【The invention's effect】
As described above, according to the present invention, in a waterproof casing formed by combining and joining divided casing components, a plurality of wiring outlets are provided at different positions, and the joint shape between the wiring outlets ( By setting the combination shape) to an inclined straight line, a curved line, or the like, the electronic component can be easily stored in the waterproof housing while maintaining the waterproof function. In addition, when a plurality of wiring outlets are required in the waterproof housing, an offset is provided between the wiring outlets, so that the position of the wiring cable in the electronic component can be freely determined regardless of the structure of the waterproof housing. Can be designed and developed. In addition, since the most suitable wiring outlet can be selected from a plurality of wiring outlets, existing electronic components can be mounted on the waterproof housing without modification, thereby reducing product costs and shortening the development period. be able to.
