Description

[Detailed Description of the Invention] The present invention relates to an improvement in the front cover structure of a housing for electronic equipment, etc.

Conventionally, the housing structure in which multiple component circuits and component devices such as electronic equipment and communication equipment are mounted on a rack in a shelf-like manner has been configured with various functions or one system in each rack. It had a single-panel structure or a two-panel double-panel structure, allowing the entire structure to be seen when the door was opened.

However, recently, with the miniaturization of circuit components and advances in packaging technology, it has become possible to mount a plurality of functional devices or systems within one rack.

Therefore, front doors have also been separated and miniaturized, front covers have been attached to each of the functional devices or systems, and only the necessary front covers have been removed for maintenance and inspection.

At that time, the removed front cover is placed on a desk placed near a storage rack for electronic devices, etc., or if there is no desk, it is placed on the floor, so the surface may become dirty or scratched and the appearance may be affected. There was a problem in that not only did it damage the quality of the product, but also the printing on the nameplate attached to the surface became unclear or illegible.

The purpose of the present invention is to eliminate the above-mentioned problems, and the purpose is to removably fasten the front cover to the container component by means of a fastening member having a neck protruding forward from the front surface of the front cover. The present invention provides a housing structure for electronic devices, etc., characterized in that the upper part of the cover is provided with means that can engage with the necks of the plurality of fastening members to which other surface covers are fastened when the cover is removed. Become a distant relative.

The present invention will be explained below using the drawings.

FIG. 1 is a schematic perspective view of a housing for electronic devices, etc. in one embodiment of the present invention, FIG. 2 is a perspective view of a front cover of the housing, and FIG. 3 is a mounting portion of the front cover. cross section,
FIG. 4 is a side view of the removed front cover when it is engaged with another attached front cover fastening member, and FIG. 5 is a side view of the detached front cover when it is engaged with another attached front cover fastening member, and FIG. This is an example.

In FIG. 1, a housing 1 for electronic equipment, etc. consists of a pair of support frames 2 and 2' facing left and right, an upper frame 3, a lower frame 4, and a side plate 5.
, a plurality of component devices 6 such as electronic devices, and a plurality of front covers 7.

The upper frame 3 and the lower frame 4 are respectively fixed to a pair of support frames 2 and 2' to form an integrated structure, and the integrated structure is engaged with a side plate 5 and a rear plate (not shown). It covers both sides and the rear.

On the other hand, the component device 6 and the front cover 7 are screwed onto the component members of the support frames 2 and 2', respectively.

As shown in FIGS. 2 and 3, the front cover 7 has a large number of tapped holes 8 and 8' (first holes) bored in the support frames 2 and 2'.
A pair of necked thumbscrews 9 are rotatably attached to the left and right sides at the same intervals as those shown in Figure), and outer edges 10 to 13 are formed by bending each side of the rectangle in front view 90° backward. It is.

A pair of necked knob screws 9 are provided on the outer edge portion 10 of the upper side.
A pair of rectangular windows 14 facing each other are bored.

However, the short side A of the window 14 is a circular knob 15 with a thumbscrew 9.
The dimension is slightly larger than the thickness t of
The dimension C from the rear edge of the top outer edge 10 of the front cover is slightly smaller than the diameter of the neck 16 of the thumbscrew 9.
It is slightly smaller than the length L.

Note that a pair of screw bushes 17 fixed to the back side of the front surface of the front cover 7 and corresponding to the thumbscrews 9 are connected to the thumbscrews 9.
The E-ring 18 is engaged with the threaded portion of the front cover 7 to prevent the thumbscrew 9 from falling off the front cover 7 when the front cover 7 is removed.

As shown in FIGS. 1 and 3, such a front cover 7 is installed by screwing thumbscrews 9 into tapped holes 8 and 8' in the support frames 2 and 2'.

As shown in FIG. 4, among the plurality of front covers 7a to 7d attached to the support frames 2 and 2', the front cover 7C is
The circular knob 1 of the thumbscrew 9 that attaches the upper surface cover 7a when removed from the support frame 2, 2' in order to operate the component 6C mounted behind it as required.
5 can be engaged with a rectangular window 14 shown in FIG.

Note that the engaging means formed on the upper outer edge portion 10 of the front cover 7 does not have to be a rectangular window 14 as shown in FIG.

That is, FIG. 5 shows an embodiment in which a retaining means is formed in a shape different from that of the rectangular window 14, and FIG. Figure b shows a dovetail cutout 20. In Figure C, a circular window 21 is provided to enable engagement with the necked knob screw 9.

As explained above, the housing structure for electronic devices, etc. according to the present invention is practical because it prevents the removed surface cover from being accidentally dropped and damaged when placed on a desk, or soiled or damaged when placed on the floor. effective.
