Description

[Detailed Description of the Invention] The present invention relates to a mounting device for appropriately fixing a pushbutton switch to a panel.

Conventionally, this type of mounting device mainly consists of two curved spring plates fixed to the pushbutton switch body with rivets, or a spring plate with the tip divided into four strips, and the base section fixed to the pushbutton switch body as appropriate. There has been provided a method in which the switch body is fitted and fixed to the switch body, and the mounting hole edge of the panel is elastically sandwiched between the flange portion of the switch body and the tip of each spring plate.

However, with this type, the shape of the mounting bracket is complicated and fixing it to the switch body is troublesome, and there are many machining steps, which increases costs, and the spring plate is curved, so there is no need for extra work during installation. It has the disadvantage that it tends to crack when external force is applied to it.

The present invention was developed in view of the above-mentioned drawbacks, and its purpose is to provide a mounting device for a pushbutton switch that is easy to process and inexpensive, and that can be easily fixed to the switch body while also being strong. It's about doing.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described with reference to the accompanying drawings, which are exemplary embodiments.

Reference numeral 1 denotes an illuminated pushbutton switch body, in which two illumination lamps 4, 4, a pushbutton cap 5, etc. are housed, and the upper half forming a flange portion 6 has a circular cross section and a switch mechanism (not shown). The lower half, which houses the lower half, has a substantially rectangular cross section with chamfered corners, and a stepped portion is formed at the boundary between the upper and lower halves so that the upper half protrudes.

Further, as shown in FIG. 2, the two opposing side surfaces 2, 2 of the lower half are formed with a shallow recess 2a and an opening 2b.

Reference numeral 7 denotes a mounting bracket integrally formed from a spring material by press working, and has a locking piece 9 cut inwardly into the base 8 and capable of fitting into the edge of the opening 2b of the switch body 1; Bend the projecting pieces 10, 10 that protrude upward from both sides of the base 8 along the bending line A along the chamfered parts 3, 3 of the switch body 10, and bend them diagonally outward at the bending line B.
Further, the engaging piece portion 11 is formed by bending the projecting pieces 10, 10 diagonally outward along a substantially diagonal bending line C.

Next, explaining the mounting method, a mounting hole 13 slightly larger than the circular portion of the switch body 1 is formed in the panel 12, and two mounting fittings 7 are prepared for one switch.

The mounting bracket 7 fixes the base 8 to the opposing side surfaces 2.2 of the switch body 1 by fitting its locking piece 9 into the opening 2b.

The base 8 is formed to have the same width as the recess 2a on the side surface 2, and its position is regulated in the vertical direction by the edge and step of the recess 2a.
In the left and right direction, the lower part 10a of the protruding piece 10 is the switch body 1.
The position of the opening 2b is regulated by coming into contact with the chamfered portion 3 of the opening 2b, and the opening 2b is securely fixed by sandwiching the edge of the opening 2b between the base 8 and the locking piece 9.

In order to firmly clamp the edge of the opening 2b, the locking piece 9 preferably has a cut-and-raise angle θ slightly smaller than 90°.

The pushbutton switch main body 1 with the pair of mounting brackets 7 fixed as described above is inserted into the mounting hole 13 of the panel 12 from above, and the edge of the mounting hole 13 is connected to the flange portion 6 and the protrusion 1 of the mounting bracket 7. Attach by elastically clamping it with the tip.

During this insertion, the end surface 11a of the engagement piece 11 of the protruding piece 10 of the mounting bracket 7 contacts the edge of the mounting hole 13 and bends slightly inward, and when it is completely inserted, The panel 12 is protruded and sandwiched between the flange portion 6 and the flange portion 6 as described above.

Note that even if the protruding piece 10 is bent inward, that is, in the direction indicated by the arrow in FIG. The switch body 1 is not damaged or the protruding piece 10 is prevented from being cracked.

Further, since the projecting piece 10 has elasticity, the panel 12
Even if the thickness of the plate differs, it can be accommodated.

According to the present invention, the upper half shaped like a flange portion of the switch body has a circular cross section, the lower half has a substantially square cross section, the corners are chamfered, and the upper half protrudes at the boundary between the upper half and the lower half. The two opposing sides of the lower half form a recess with a shallow bottom and an opening in a part of the recess, while the base of the mounting bracket made of spring material Since a locking piece that can be fitted into the opening is formed, even if the upper half of the switch body has a circular cross section, the mounting bracket can be attached to the switch body simply by fitting the locking piece into the opening. It is stable because it adheres tightly to the lower half, and its position is restricted in the vertical direction by the edges and steps of the recess, so it does not wobble.

Furthermore, since the projecting pieces projecting upward from both sides of the base of the mounting bracket are bent along the chamfered corners of the switch body, the mounting bracket will not slide sideways.

Furthermore, since the mounting bracket has no curved parts and is entirely bent into a straight line, it is not only strong but also easy to process and can be manufactured at low cost.
