Description

[Detailed description of the invention] The present invention relates to an equipment mounting device for installing equipment for a switchboard, etc. on a panel, and in particular, the equipment that is inserted from the front side of the panel into a hole provided in the panel is fixed on the back side of the panel. The present invention relates to an instrument mounting device.

Figure 1 shows a typical example of a fixture mounting device for attaching conventional switchboard fixtures, etc. to a panel. A front plate that appears on the surface of the panel 2 when attached to the panel 2 is formed integrally with the instrument body 1, and the front plate 3 has screws 4 for attaching the instrument body 1 to the panel 2. It is inserted. On the other hand, the panel 2 has a hole 5 for inserting and attaching the instrument body 1 and a screw hole 6 for inserting the screw 4. After the instrument body 1 is inserted into the hole 5 of the panel 2, It is fixed with a screw 4 via a spring washer 7 and a nut 8.

However, in the conventional instrument mounting device having the above-mentioned configuration, a plurality of mounting screws 4 are used.
However, since it is provided so as to protrude from the peripheral surface of the front plate 3 of the instrument body 1, it requires a large amount of space, which hinders miniaturization of the instrument and also causes a deterioration in quality in terms of design, etc. , and it takes time to install and remove because the screws are tightened.

The present invention was developed in view of these points, and it eliminates the time required for tightening screws during installation or removal, allows the main body of the device to be easily fixed to the panel, and furthermore saves space due to the installation screws. To provide an instrument mounting device that does not have any problems and does not impair the quality of its design.

An embodiment of the present invention will be described below with reference to the attached FIGS. 2 to 4.

FIG. 2 shows the instrument mounting device according to the present invention, and FIG. 3 shows the relationship between the instrument body and the instrument mounting device.

In FIGS. 2 and 3, the tip of the instrument mounting device 9 according to the present invention is made of an elastic material such as phosphor bronze, and is opened in a V-shape, so that the instrument can be attached to the panel 10. After panel 1
An elastic arm 11 is formed to push the back surface of the instrument mounting device 9, and a guide arm 12 is formed in the center of the instrument mounting device, protruding from both sides and having an L-shaped cross section. A protrusion 13 is provided, a protrusion 15 used when removing the instrument body 14 from the panel 10 is provided at the rear end, and a claw 16 for fixing the instrument body 14 and the instrument attachment device 9 is provided at the rear end. is provided. On the other hand, the instrument main body 14 has grooves 17 parallel to the insertion direction, into which the guide arms 12 of the attachment device 9 are inserted, at a total of four locations on both the upper and lower ends of both sides, and the grooves 17 are formed at the rear of the upper and lower surfaces. 16
A hole 18 is drilled through which the can be engaged.

FIG. 4 shows a state in which the instrument body is fixed by the instrument attachment device.

After inserting the instrument body 14 into the hole of the panel 10 from the front side of the panel 10, on the back side of the panel 10, while holding a part of the instrument body 14 with one hand, insert the instrument body 14 into the groove above the instrument body 14. 17
By inserting the guide arm 12 of the instrument mounting device 9 into the panel 10 and pushing the protrusion 13 with a screwdriver or the like, the entire instrument mounting device 9 advances toward the panel 10.
The elastic arm 11 is in contact with the back surface. When the elastic arm 11 is pushed further, it bends because it is made of an elastic material such as phosphor bronze, and at this time, the claw 16 of the instrument attachment device 9 is inserted into the locking hole 18 provided in the instrument body 14. Immerse yourself in it. Similarly, if the instrument body 14 is attached to the lower surface side of the instrument body 14 using the instrument attachment device 9 which is turned over than the instrument attachment device 9 attached to the upper surface side, the elastic arm 11 and the instrument body 14 can be attached to each other. The claws embedded in 18 repel each other, and the instrument main body 14 can be fixed.

When removing an instrument from the panel 10, engage a screwdriver or the like with a protrusion 15 provided on the instrument attachment device 9, lift it upwards, and insert the claw 16 into the instrument body 14.
The instrument can be removed by removing it from the hole 18 and removing the instrument attachment device 9.

Next, as shown in FIG. 5, the same effect as in the first embodiment can be obtained by changing the elastic arm 19 from the left and right elastic action of the first embodiment to an elastic arm 19 having vertical elastic action.

As explained above, according to the present invention, there is no need to tighten screws, reducing the number of man-hours, making it possible to easily attach and detach instruments to and from panels with a single touch, and to make simple holes in the panel. Machining is easy because a square hole can be used, and the device mounting device only needs to have the same shape on the top and bottom, and can be easily formed using a press, etc., and the shape of the device body is simple, so the manufacturing cost is low. If the width of the instrument main body is constant, a single-shaped instrument mounting device can be applied to instruments of different heights, and there are effects such as standardization of the mounting device.
