Description

[Detailed description of the invention] Industrial application field: This invention relates to a device for mounting small control devices such as circuits, disconnectors, and timers on panels.

Prior Art: An example of a conventional panel mounting device is shown in FIGS. 1 and 2. That is, reference numeral 10 denotes a resin attachment member that can be attached to the device main body 1, and a pair of mount springs 12 and 13 are integrally extended downward from the flange portion 11 of the attachment member 10. The mount springs 12 and 13 each have elasticity by bending and bulging the midsection toward the outside, and when the mounting member 10 is attached to the device body 1, the free ends 12A and 13A of the mount springs are attached to the device body 1. It is formed so that it is held in contact with or close to the side wall of the. Further, the outer surfaces of the mount springs 12 and 13 have their base ends 12B and 1
From 3B to the peaks 12C and 13C, uneven mounting portions 12D and 13D of equal height are formed in a sawtooth shape. When installing the main body 1 of the device in the mounting hole P ₁ of the panel P with such a device, attach the mounting member 1 to the main body 1.
0 attached, support the mount springs 12 and 13 from the front side of the panel P by squeezing them inward with your fingers or the like against their elasticity, and attach the mounting device 10.
In this state, the mount springs 12 and 13 are released and outward elasticity acts, so that the uneven mounting portion 12D and 13D are mounting holes of panel P
The main body 1 is fixed to the panel P by pressing the inner surface of _P1 .

Purpose of the invention; By the way, in the above-mentioned mounting device, since the heights of the uneven mounting portions 12D and 13D formed on the mount spring are approximately equal on the same surface, it is particularly difficult to use when the panel thickness is relatively thin. The disadvantage is that it cannot be fixed securely. In other words, the elastic force of the mount spring in such a mounting device is
A from the back side of panel P mainly in the installed state
Since the elastic force of the mount spring acts near the point, if the panel thickness is thinner than a certain value, the elastic force of the mount spring stops acting.

This idea was developed in consideration of the above points, and the purpose is to provide a mounting device that can securely fix panels of various thicknesses, from relatively thick to relatively thin. shall be.

Structure of the invention: An embodiment of this invention will be described in detail with reference to FIGS. 3 to 5. Reference numeral 2 designates a mounting member made of a resin material according to the present invention, in which a pair of mount springs 4 and 5 are integrally extended downward from a flange portion 3 that essentially constitutes a cap. The mount springs 4 and 5 each have elasticity by bending and bulging their midsections outward in a substantially rectangular shape, and the mounting member 2 is attached to the main body 1 of the device.
The free end of the mount spring when attached to
A, 5A are formed so as to be in contact with the side wall of the device main body 1 or to be maintained in a state close to this. The feature of the mount spring according to this invention is that its base end 4
From B, 5B to the peaks 4C, 5C, the groove 40
and a concave-convex mounting portion 41 with different heights sandwiching 50,
42 and 51, 52 were formed. That is, to explain in detail with reference to FIG. 5, one side of the uneven mounting part has sawtooth shaped uneven mounting parts 41 and 51 of equal height, similar to the conventional mounting device. Also, the remaining one side is the base end 4B of the mount spring.
and 5B, protrusions 42A and 52A are formed adjacent to the protrusions and protrusions 5B, and protrusions 42B and 52B are formed with the protrusions and protrusions having a lower height on the side of the peaks 4C and 5C. In other words,
High convex shape 42 on the corresponding part on the front side of the panel
A and 52A are formed, and low-height convex shapes 42B and 52B are formed to correspond to each other on the back side of the panel. For this reason, the mounting device 2 according to this invention
When it is attached to a relatively thick panel, the elastic force of the concave and convex mounting parts 41 and 51 on one side, where the height of the concave and convex portions are formed evenly, acts at point A, so that stable fixation can be obtained. , On the other hand, if the panel is installed on a relatively thin panel, tall convex shapes 42A and 52A are attached to the corresponding parts on the front side of the panel.
Since the elastic force of the concavo-convex mounting portions 42 and 52 on one side that has been formed acts at point B, stable fixation can be obtained.

Effects of the invention: As mentioned above, according to the mounting device of this invention, 2
By combining different sets of uneven mounting parts, reliable and stable fixation can be obtained even for panels of various different thicknesses.

According to the illustrated embodiment, the pair of mount springs 4 and 5 are connected to each other through the grooves 40 and 50.
Although sets of uneven mounting portions of different heights are formed, the number of mounting springs may be one or more pairs, and the number of uneven mounting portions of different heights is not limited to two sets.

Further, although the mounting device 2 of the embodiment has a cap shape and is formed to be able to be attached to the device main body 1, this invention is not necessarily limited to the shape of the embodiment. It is also possible to have a configuration in which a mount spring is attached directly to the outer peripheral part of the mount spring. In this case, the portion corresponding to the free end of the mount spring in the embodiment may be fixed to the main body 1, and the side corresponding to the base may be made the free end of the mount spring.

It goes without saying that this invention can be modified in various ways without departing from its gist.
