Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mounting device suitable for mounting control equipment components such as switches, indicator lights, plugs, etc. on a panel.

Conventionally, as a method for attaching control equipment parts such as switches, indicator lights, and plugs to panels, an elastic piece is provided on the side of the body of the switch, etc., and the body is inserted into the panel with one touch using the elasticity of the elastic piece. It is well known that two types of devices have been put into practical use: one in which a screw is cut on the outer periphery of the main body, and another in which the main body is attached and fixed to a panel by tightening a nut on the threaded part. It had been made into

However, in the case of the former, that is, a mounting device using an elastic piece, the main body can be quickly mounted on a panel with a single touch, but on the other hand, it has a lever-like handle, for example. In the case of switches, in addition to the disadvantage that the operating side of the switch lifts up from the panel when operated,
Particularly in the case of a round main body, there is a drawback that the main body rotates when an external force is applied to the main body. When the main body of a switch or the like is round, and the upper surface is square or directional, even a slight rotation of the main body causes the problem of an unsightly appearance.

Next, in the case of the latter, that is, a mounting device in which the main body is provided with a screw and tightened with a nut to attach and secure it to the panel, the main body must be held down while tightening the nut when mounting to the panel.
There is a problem in that it requires a lot of work to tighten the nuts, and at the same time, when installing the main unit on a panel of a particularly large device, one person should hold the main unit, such as a switch, from the front of the panel, and the other person should hold it from the back side. There were also problems such as the need for a person to tighten the nuts and the need for two people to install the main body.
Furthermore, after the main body is attached to the panel by tightening the nuts, there has been a problem in that the nuts for fixing the attachment loosen due to vibrations of the equipment and the like. If the nut becomes loose, the main body of the switch or the like may rotate, displace, or shake, causing the lead wires connected to the main body to cross, short-circuit, come off, or break. There was a risk that various problems would occur.

The present invention has been developed in view of the above-mentioned conventional circumstances, and therefore, the purpose of the present invention is to provide a single device with the advantages of both the elastic piece-based mounting device and the screw-based mounting device. The object of the present invention is to provide a new mounting device for electrical equipment such as a switch, which can eliminate the above-mentioned conventional drawbacks.

Another object of the present invention is that one-touch mounting using an elastic piece or firm mounting using screws can be carried out as needed with one mounting device, and in the case of screw mounting, it is possible to perform mounting with a single touch using an elastic piece or firmly mounting with screws. Another object of the present invention is to provide a new mounting device for electrical equipment such as switches, which is extremely reliable and can maintain fixation stability over a long period of time.

The above-mentioned object of the present invention is to provide a main body of a switch or an indicator light, etc., with a flange on the outside of the upper surface, and to provide a threaded part on the outer periphery of the main body, and a part of the threaded part has a vertical groove or a notch. An electrical device such as a switch, characterized in that a plurality of the above-mentioned vertical grooves or holes are provided with elastic pieces extending from below, and the plurality of vertical grooves or holes are formed with elastic pieces extending from below, so that the installation can be performed both by insertion and by tightening the screws. This is accomplished by means of a mounting device.

Next, a preferred embodiment of the present invention will be explained in detail with reference to the drawings.

Figures 1 to 4 show an embodiment in which the present invention is applied to a switch, of which Figure 1 is a partially sectional front view of the main body attached to a panel with an elastic piece, and Figure 2 is a front view of the main body. Fig. 3 is a perspective view, and Fig. 4 is a partially sectional front view of the case where the
The figure is a bottom view.

In the figure, reference numeral 11 indicates the main body of the switch, and a screw 1 is provided on the outer periphery of the main body 11 approximately in the middle.
2 is formed, and a vertical groove 1 is formed in a part of the screw 12.
3 is cut out. Although two vertical grooves 13 are formed in this embodiment, three or four or more vertical grooves 13 may be provided, and each vertical groove 13 is provided with an elastic piece 14, respectively. Instead of the vertical groove 13,
Of course, it is also possible to form a defect in which the longitudinal groove is widened considerably, that is, cut into a flat shape. The vertical groove 13 is formed with a screw 1, taking into consideration that it will be attached to the panel by tightening with a nut 15 (the dimension of the clearance of the elastic piece 14).
It is desirable to form the groove a little deeper than the bottom of the valley No. 2. In the illustrated embodiment, the elastic piece 14 is formed by extending upwardly a part of an elastic body fitted by fitting a hole into a protrusion 11a provided at the lower part of the main body 11. It is of course not necessary to employ such a structure in which the fitting is performed in a concave-convex relationship, and various other structures such as screws or rivets may be employed. The elastic piece 14 may also be formed integrally with the main body 11 from a somewhat elastic material such as synthetic resin. Therefore, in that case, there is no need to separately prepare an elastic piece. In addition, reference number 15 is Natsu,
Reference numeral 16 indicates a flange formed on the upper part of the main body 11, reference numeral 17 indicates a handle, and reference numeral 18 indicates a panel 19, a terminal.

FIG. 1 shows the elastic piece 14 of the attachment device according to the present invention.
shows the state in which the main body 11 is attached to the panel 18, and as shown in the figure, the main body 11 is attached to the hole 1 of the panel 18.
8a, and is inserted into the panel hole 1 by the elastic piece 14.
By pressing the inner wall of 8a outward, the main body 11
is attached and fixed to the panel with one touch.

FIG. 2 shows a state in which the main body 11 is attached to the panel 18 by the screws 12 of the attachment device according to the present invention, and is a diagram when the nut 15 is screwed onto the screw 12 in the state shown in FIG. 1. When attaching the main body 11 to the panel 18 with this nut 15, normally,
That is, before installation on the panel of the device, as shown in FIG. As shown in FIG. 6, the thread of the nut 15 is constantly pressed by the elastic force of the elastic plate. Therefore, even if vibrations, shocks, etc. are applied to the main body, loosening of the nut 15 can be prevented, and therefore, there is a great effect that loosening and rattling between the panel and the main body can be completely prevented.

FIG. 7 is a perspective view of a main part showing a modification of the present invention in which the handle of the above-described embodiment is made into a lever-like handle. As shown in the figure, a lever-shaped handle 27 is used in place of the handle 17 of the previous embodiment, but other elements are completely the same as in the previous embodiment.

The embodiment described above is a case where the present invention is applied to a switch, but the present invention is applicable to switches such as push button switches, toggle switches, waveform switches, etc. Of course, the present invention can also be similarly applied to other control equipment parts such as.

According to the present invention, as explained above, one switch can be used for both one-touch installation using an elastic piece and screw-tightening installation, making it possible to perform installation according to the nature and situation of the equipment to be installed. Moreover, in the case of screw (nut) tightening installation, the elastic pieces provided in the vertical grooves or holes press the nut outward from the inside, so the external force is reduced by the pressing force. This has the dual effect of accurately preventing the nut from loosening relative to the main body, which is caused by vibrations and the like.

Further, according to the present invention, unlike the conventional method, it is possible to achieve the effect that one-touch insertion mounting and screw mounting can be performed using the same panel mounting hole size.

Furthermore, according to the present invention, the mounting device of the main body can be used for both one-touch mounting and screw-tightening mounting, so there is no need to manufacture a main body with dedicated mounting devices for each. Distributors, users, etc. can standardize the models, and inventory efficiency is also good.
