Description

[Detailed description of the invention] (a) Description of the technical field to which the invention belongs
This invention relates to the structure of a device for attaching small devices, including various switches such as lever switches, as well as indicator lights, to a panel.

(b) Description of Prior Art Conventionally, as shown in Fig. 1, as a device for attaching this type of small equipment to a panel, the mounting plate 2 of the equipment is tightened with screws 3 and nuts 4, and then attached to the panel 5. There were many things to install. However, this conventional device has the disadvantage that it is troublesome to tighten and fix the device using two screws and nuts, requires a large number of man-hours, and has extremely poor workability. Also, in the case of particularly large mounting panels, one person cannot reach both the front and back of the panel, so it is necessary to tighten machine screws on the front side and hold small devices and nuts on the back side, so two people end up There was a problem in that the installation could not be accomplished without a lever. Furthermore, in the case of a small switch like the one shown in FIG. It was inconvenient that it was necessary to prepare one with a different height H.

(c) Explanation of the purpose of the invention The present invention was made to improve the above-mentioned drawbacks of the prior art.Therefore, the purpose of the present invention is to simply mount equipment on a panel by devising the shape of the mounting plate. Installation is accomplished by simply inserting it into the mounting hole,
To provide a mounting device that is extremely easy to install and has good workability.

(d) Structure of the device In order to achieve the above object, the present invention provides approximately vertical forked portions on the left and right sides of a mounting plate fixed to the top surface of a main body such as a switch body. protrusions are formed facing each other on the outside or inside of the tip of the forked portion, and a pair or a plurality of pairs of locking portions at different positions are formed at intervals with respect to the protrusion in the fork-shaped portion, and the mounting portion is mounted. By inserting the fork into the mounting hole selected according to the panel thickness,
The edge of the attachment hole is configured to be elastically fitted and locked between the lower end portion of the projection and the locking portion.

(e) Description of embodiments of the invention Next, preferred embodiments of the invention will be specifically explained with reference to the drawings.

FIGS. 2 to 8 are diagrams showing an embodiment in which the present invention is applied to a push button switch. As shown in the perspective view of FIG.
2a and the cover 12 is fixed. Further, a mounting plate 13 is fixed to the cover 12 by caulking using the lower part of the sleeve 14.

Forked portions 15 are provided on the left and right sides of the mounting plate 13, and the forked portions 15 stand vertically or with their upper ends slightly facing outward. Opposing protrusions 15a are formed on both outer sides of the upper end of the forked part 15,
Further, a first locking portion 15b is formed on the inner side at a position below this protrusion 15a, and a second locking portion 15c is formed on the outer side further below. Reference number 16 indicates an operator.

The A' dimension of the forked portion 15 is set to be slightly larger than the A dimension of the mounting hole 18 of the panel 17. Therefore, after the fork 15 is inserted into the attachment hole 18, the fork 15 is pressed against the edge of the attachment hole 18 (see FIG. 3). Note that devices such as switches are inserted from below the panel. Figure 4 shows the state in which it is inserted into the thick mounting panel 17a, and Figure 5 shows the state in which it is inserted into the thin mounting panel 17b.The mounting holes at that time are shaped as shown in Figures 7 and 8, respectively, depending on the panel thickness. You can set it to . In the case of a thick mounting panel 17a, the edge of the mounting hole 18 is locked by the protrusion 15a and the locking portion 15c as shown in FIG. 4, thus ensuring accurate mounting of a switch or the like to the panel. In the case of a thin mounting panel 17b,
Since the mounting hole 18 is provided with the projecting portion 18a, the lower surface of the projecting portion 18a is locked to the upper surface of the locking portion 15b, and the edge of the mounting hole 18 is connected to the projection 15a.
As a result, proper and secure installation can be achieved.

Therefore, by using the mounting plate of the present invention, it is possible to adapt to both thick and thin mounting panels, and even if the panel thickness changes, the amount of protrusion of the operator from the top surface of the panel is always constant and the height h will not change.

In the above embodiment, the locking portion 15b can be removed to provide a mounting device exclusively for thick panels, or the locking portion 15c can be removed to provide a mounting device exclusively for thin panels.

In addition, the B' dimension (between the forked parts) shown in Fig. 6 is
By setting the size slightly larger than dimension B of the mounting hole, it is possible to securely install the mounting hole without shaking in the left-right direction in the state shown in this figure. In addition, when the upper end of the forked part 15 is made to stand up slightly outwardly, if a chamfer is provided on the upper end of the forked part 15, there is no problem in inserting it into the attachment hole.

Furthermore, if the outer upright portion between the protrusion 15a and the locking portion 15c is provided with, for example, sawtooth-like irregularities, the attachment of a switch or the like to the panel hole becomes even more reliable.

9 to 11 are diagrams showing partial modifications of the present invention, in which the present invention is applied to a waveform switch. In this modification, the shape of the locking portions 15b provided facing each other on the inside is changed. That is, the locking portion 15b is bent outward.
Correspondingly, the mounting hole of the mounting panel is the 10th
Make it into the shape shown in Fig. 11. In this case as well, switches and the like are inserted from below the panel. In the case of a thin mounting panel, the mounting hole 18 shown in FIG. 11 is used to lock and secure the panel to the locking portion 15b.
For thick mounting panels, as shown in Figure 10,
By providing the mounting hole 18 with the retracting portion 18b, the mounting hole 18 is not locked to the locking portion 15b but is locked to the locking portion 15c.

(f) Explanation of effects of the invention The invention is constructed as described above, and the invention provides the following effects.

By simply inserting a switch or the like into the mounting hole of the panel in a straight or parallel state, the mounting can be easily achieved with one touch, and the mounting is extremely simple and the workability is also excellent. Furthermore, with the conventional method of tightening and fixing with machine screws and nuts, it was not possible to perform high-density installation because it was difficult to insert fingers during actual work, but with the present invention, it could not be done in high-density or narrow places. Easy to install.

According to the present invention, in particular, the switch itself,
Alternatively, it is possible to properly and securely mount panels of different thicknesses using one small switch, etc., without replacing the mounting hardware, and furthermore, the amount of upward protrusion of the control from the top of the panel is always constant. It is possible to do so, and it is extremely rational. Of course, even in the case of extra-large panels, the installation work can be done by one person rather than two people.

If the switch body is larger than the mounting hole, that is,
Even if the switch body is larger than the dimensions of the switch mounting part, there is no problem in mounting it. Furthermore, even if the lead wires have been wired or the printed circuit board has been soldered to the terminals of the switch in advance, the switch can be easily attached to the panel after that.

Unlike conventional plug-in switches, when the switch is inserted into the panel, an inward force is applied that prevents the operation of the operator, causing the forked part to deform and come into contact with the operator. , therefore, no malfunction will occur.

The mounting is solid, there is no wobbling from front to back, left to right, and the mounting part will not float (come off) from the panel even if strong force is applied to the controls.

Since the number of parts in the mounting part is small, it is extremely economical.
