Description

[Detailed Description of the Invention] This invention relates to a fixture for attaching an electronic device unit such as a temperature controller to a panel.

Conventionally, in order to attach this type of electronic equipment unit to a panel, a mounting tool was screwed into place from the back of the case using a screwdriver or the like, and the panel was pressed by the mounting tool.

The object of the present invention is to provide a fixture that can be easily installed from the front side of a panel without requiring any tools.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

1 to 4 show a fixture 1 according to the present invention.

In these figures, a rectangular retaining hole 13.14 is provided in the upper surface of the U-shaped base 10, and a rectangular retaining hole 15.16 is also provided in the leg portion 11.12. There is.

Note that the legs 11.12 are bent at an angle somewhat more acute than 90°, as shown in FIG.

Further, a retaining claw portion 21 is provided at the center of this U-shaped base portion 10.

Elastic pieces 31 and 32 are cut and raised diagonally from the center of this U-shaped base 10.

This fixture 1 can be made, for example, from a single elastic metal plate through appropriate cutting and pressing processes.

5 to 8 show the two fixtures 1, 1 attached to the case 40. FIG.

In these figures, the case 40 has a knob 61 on the front and a terminal portion 62 on the back.

Although not shown, electronic circuits and the like are housed inside.

A flange portion 41 is provided at the front portion of the case 40.

Furthermore, on the side surface of the case 40, there are a total of eight rectangular engagement protrusions 43°43.44.44.45.45.46.46.
, is provided.

Further, engagement recesses 51, 51 are provided.

Each of the rectangular protrusions 43 to 46 engages with each of the rectangular engagement holes 13 to 16 of the fixture base 10, and the U-shaped base 10 is attached to the case 40.

In addition, since the U-shaped legs 11 and 12 are at an angle slightly more acute than 90°, the base 10 grips the side wall of the case 40, and the projections 43 to 46 and the holes 13 to 16 are disengaged. This is prevented.

Further, when the above-mentioned engaging claw portion 21 engages with the engaging recess 51 and the elastic pieces 31 and 32 are pushed and deformed (as shown by the two-dot chain line in FIG. 2), the base portion 10 does not come off from the case 40. That's what I do.

By keeping the fixtures 1, 1 attached to the case 40 in this manner, the case 40 can be easily attached to a panel (not shown).

That is, the panel has a rectangular hole that is smaller than the flange 41 and into which the part of the case behind the flange 41 is inserted, and the case 40 is inserted into this hole from the rear.

Then, the elastic pieces 31 and 32 are pressed by the holes in the panel, so the elastic pieces 31 and 32 are pressed as shown by the two-dot chain line in FIG.
deforms elastically.

As the insertion continues, the hole in the panel passes over the elastic pieces 31 and 32 and hits the back surface of the flange 41.

At this time, the elastic pieces 31, 32 elastically return to the illustrated state.

At this time, the end surfaces 33 and 34 of the elastic pieces 31 and 32 and the flange 41
A panel (not shown) is sandwiched between the rear surface 42 and the rear surface 42 of the camera.

In this way, the case 40 remains firmly fixed to the panel without being pulled out even if a pulling force is applied in the front direction of the panel.

As described above with respect to the embodiments, according to the present invention, attaching the electronic device unit to the panel is as simple as inserting the case into the hole provided in the panel from the front of the panel.

This installation therefore does not require any tools to operate.

Moreover, since the fixture can be fixed to the case extremely easily, the work as a whole is also extremely simple.
