Description

[Detailed Description of the Invention] The present invention relates to a switch box for accommodating a switch or the like.

Conventional switchboards required removing iron plates, processing them, and welding them together, which was time-consuming.
This had the disadvantage that the production time was unavoidably long.

In view of the above-mentioned drawbacks, the present application is an attempt to solve the above-mentioned drawbacks by making it possible to form integrally molded side walls and bottom plates by a sandwiching method without requiring welding work, and the following is an implementation of the present invention. An example will be explained based on the drawings. Reference numeral 1 denotes a switchbox main body formed of a pair of integrally molded side wall portions 2, 3 and a bottom plate 4.

The side wall parts 2, 3 consist of side wall long parts 5, 6 and side wall short parts 7, 8. Claw pieces 9 and 10 that rise upward except for three times the width
, and a gap having approximately the same width as the thickness of the side walls 2, 9 is provided between the side portions of the claw pieces 9, 10 and the side portions of the side wall longitudinal portions 5, 6 opposite to each other to form the holding portions 11, 12; In addition, the short side portions 7 and 8 of the side walls have claw pieces 1 that stand up upward in the short side direction from both side ends of the short side portions 7 and 8, excluding a predetermined width from both ends.
3 and 14, and a gap having a width substantially the same as the thickness of the side walls 2 and 3 is provided between the sides of the side walls 7 and 8 that are opposite to the sides of the claw pieces 13 and 14, and the holding parts 15 and 16 are is formed. Further, each claw piece 9, 10, 13, 14 is provided with a predetermined number of protrusions 17, 17' projecting in the direction of the clamping portions 11, 12, 15, 16, respectively.

In addition, the side ends of the longitudinal side walls 5 and 6 are bent inward at right angles, and then bent inward again at appropriate positions to form a gap that is approximately the same as the thickness of the side walls 2 and 3. The side wall portion 2, is bent again at the position where it is provided on the side, and the side wall portion 2,
The key parts 18 and 1 are provided with a gap of approximately the same width as the thickness of the key parts 18 and 1.
9, and the side wall short portions 7 and 8 form the key portion 1.
8, 19, the side end portions are bent inwardly at right angles, and then bent outwards at a position where twice the thickness of the side wall portions 2, 3 is provided outwardly. After bending the ends of the long side wall parts 5 and 6 outward again to pinch them, bend the ends of the long parts 5 and 6 outward at a position that creates a gap of approximately the same width as the thickness of the side wall parts 2 and 3 inward. A gap having substantially the same width as the thickness of the side walls 2 and 3 is provided between the opposite wall side portions to form key portions 20 and 21.

The bottom plate 4 has a hanging portion 2 from the side end in the longitudinal direction.
2, 23, and the hanging part 2 from the short side part in the transverse direction
4 and 25 are formed to hang down, respectively, and each hanging part 22, 2
On the hanging wall surfaces of 3, 24, 25, the claw pieces 9, 10,
Protrusions 17, 17' protruding from 13, 14...
Hole 2 having a shape and diameter that allows for tight insertion of ...
A predetermined number of protrusions 6, 26', . . . are formed corresponding to the protrusions 17, 17', .

Further, the shape of the flat part 27 of the bottom plate 4 is made to match the inner shape of the side wall formed by the pair of differential side wall parts 2 and 3, and key parts 18, 19, 2 are provided at two opposing corners.
Angular notches 28 and 29 corresponding to 0 and 21 are formed.

Note that the side walls 2 and 3 have the key portion 1 inward at their upper ends.
8, 19, 20, 21 are formed into flat flanges 30, 31 bent with the longitudinal width of the end face shapes, and the upper ends of the key parts 18, 20 of the side wall part 2 are connected to the key part 1.
8 and 21 and 19 and 20 are opened in the shape of the end face in a state where they are engaged, and as shown in FIG.
1, 19 and 20 are inserted so as to be sandwiched together to form the side wall of the switchbox main body 1,
The bottom plate 4 is tilted from below and accommodated inwardly between the side walls 2 and 3, and the hanging portions 22 on the longitudinal direction of the bottom plate 4 are attached to the clamping portions 11 and 12 formed inside the lower ends of the rear side wall longitudinal portions 5 and 6. , 23 are held by the hanging parts 24, 25 on the short side of the bottom plate 4 in the holding parts 15, 16 formed inside the lower ends of the side walls 7, 8, and from the claw pieces 9, 10, 13, 14. Projection 1
Hanging parts 22, 23, corresponding to 7, 17'...
The switch box main body 1 is formed by being fitted into holes 26, 26' of 24, 25 and fixed.

In addition, as shown in FIG. 6, in the other embodiment of the present invention, if the differential side wall portions are formed only at one corner of the side wall portions instead of forming a pair, assembly is easy and strength is improved. It has the following.

That is, a key part 33 is formed at one end of the side wall part 32, a key part 35 is formed at one end of the other side wall part 34 integrally molded with the side wall part 32, and the key part 33
By inserting the keys 33 and 35 into each other, the side walls of the square switchbox main body can be easily formed.When assembling, the key parts 33 and 35 that engage with each other are made slightly larger, and after insertion, By striking the key parts together, a switchbox that is strong as a whole can be easily formed.

In short, the present invention provides a pair of side walls 2, 3 that are integrally molded in the shape of a differential, with key portions 33, 35 formed at both end portions so as to sandwich each other. Claw pieces 9, 10 rising upward at the lower ends of the side wall longitudinal parts 5, 6 and the side wall short parts 7, 8,
13, 14 are formed and the holding parts 11, 12, 15,
16, and claw pieces 9, 10, 13, 14
There are protrusions 1 in the direction of the clamping parts 11, 12, 15, and 16.
A predetermined number of protrusions 7, 17'... are provided, and the protrusions 17, 1
The hanging parts 22, 23, 24, 25 of the bottom plate 4, which has hanging parts 22, 23, 24, 25 formed on the periphery, with holes 26, 26'... corresponding to the holes 26, 26'... , 15, 16, the switchbox can be manufactured without any welding work as in the past, improving work efficiency. ，
17'... are inserted, so the bottom plate 4 is fixed and the clamping parts 11, 12, 1 are fixed even when subjected to large shocks and vibrations.
The practical effects of this are extremely great, such as being able to prevent separation from the switchbox 5 and 16, and improving the strength of the switchbox main body 1 in this respect.
