Description

[Detailed Description of the Invention] The present invention relates to a casing formed by assembling a cover and a chassis by partially overlapping each other.

Conventionally, the positioning when assembling the case cover and chassis was as shown in FIG. It fitted from above into a slit 6 formed between the plate 5 and abutted against the peripheral surface of the front knob 4 to form a button.

The positioning of the cover 1 and the chassis 3 only in the front part of the case is insufficient in the vertical, horizontal, and horizontal directions, especially in the vertical direction. Therefore, when fixing the cover 1 to the chassis 3, separate screw holes 7 Align the screw insertion hole 8 with the second
It was necessary to position it as shown in the figure and then fix it with the screws 26, which took a lot of time and made the assembly work inefficient.

The present invention was developed in view of the above points, and in addition to the folding plate and slit portion for positioning on the front part of the chassis of the conventional case, a tongue piece for regulating the lower limit position of the cover is added to the chassis. In addition to being provided on the bottom plate, protrusions for regulating the lateral position of the cover are provided on the bent plates on both sides of the chassis to facilitate positioning and improve the efficiency of assembly work.

Hereinafter, one embodiment of the present invention will be described based on FIGS. 3 to 5.

Reference numeral 9 denotes a chassis made of a metal plate for attaching electrical parts, etc., and this chassis 9" includes a bottom plate 10 and a front panel 11.
and bent plates 12 and 13 on both sides, each of which is bent inward at approximately right angles.

At the bent portion between the bottom plate 10 and the bending plates 12.13 on both sides, a tongue piece 14 for a stopper is provided protrudingly on the same plane as the bottom plate 10. A U-shaped protrusion 15 is located at the upper part of the piece 14, and this protrusion 1
5. A screw hole 16 is provided in the middle shaft.

A vertically elongated slit portion 1T is formed at the boundary between the front panel 11 and the bent plates 12 and 13 on both sides.

Reference numeral 18 denotes a cover for protecting electrical components etc. attached to the chassis 9, and this cover 18 covers the top plate 19, side plates 20, 21, . It consists of a back plate 22, a button, and a folding plate 23, and the side plates 20, 21 are provided with insertion holes 25 for screws 24.

Further, a folding plate 23 is protrudingly provided on the inner side of the front portion of the cover 18 so as to come into contact with the peripheral edge surface of the front panel 110 of the chassis 9 and fit into the slit portion 17 .

To cover and fix the stolen cover 18 over the chassis 9, first fit the folding plate 23 of the cover 18 into the slit 17 of the chassis 9 from above and adjust the position of the cover 18 in the front-rear direction. regulate.

At this time, the lower limit position of the cover 18 is at the tongue piece 1 of the chassis 9.
4, and the horizontal position is controlled by the protrusion 1 of the chassis 9.
5, the cover 18 is regulated at a predetermined position relative to the chassis 9.

In this state, insert the screw 24 into the screw insertion hole 2 of the side plates 20, 21.
The cover 1 is screwed into the screw hole 16 of the protrusion 15 through the screw 5.
8 is fixed to the chassis 9.

□Since the present invention has been adopted as described above, positioning of the cover 18 and the chassis 9 is easy, and the assembly work is extremely efficient.

Further, a screw hole 16 is provided in the protrusion 15 of the chassis 9,
When the cover 18 is fixed by screwing the screw 24 into the screw hole 16, the screwing operation becomes extremely easy since the side plates 20 and 21 are in contact with the protrusion 15.
