Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mounting device for a push switch such as a switch for blinking an interior light of an automobile or the like.

[0002]

[Prior art]

 As an attachment device for this kind of operation part, there is one conventionally proposed by the present applicant, for example, the one described in Japanese Utility Model Laid-Open No. 4-25125. In this conventional technique, in which an operation part such as a push switch is attached to a mounted body, a hole is formed through the surface of the plastic molded body, and the mounted body on both sides of the hole is sandwiched by the holes. A pair of locking step edges is projected on the surface, and a pair of locking edges, an eaves piece, and a stop wall are formed on the surface of the mounted body near the end of the hole. The edge of the flange of the operation component inserted between the lower surface of the eaves piece and the surface of the mounted body between the edges is locked by the pair of locking step edges and the stop wall, and the operation part is also provided. The operation knob attachment device is a device for attaching the operation component, which is exposed on the opposite surface of the attached body through the hole.

[0003]

[Problems to be solved by the device]

 The above-mentioned conventional technique allows the push switch to be attached to the locking step edge or the eaves piece of the substrate with the flange without using a screwing means, but cannot be applied to a box type push switch without a flange. There was a problem.

In order to eliminate the above-mentioned problems, an object of the present invention is to prevent a delusion by attaching a push switch having no flange to a plastic base body with one touch without using screwing means. To do.

[0005]

[Means for Solving the Problems]

 The above-mentioned object of the present invention is to allow the operation piece of the push switch to be loosely inserted into the hole of the base between the pair of locking bullet pieces integrally projecting on the plastic base, and to project to the opposite surface on the opposite side. The insulating plate was inserted through the holes that were provided, and the projecting pieces on both sides were press-fitted into the locking bullet pieces while flexing outward against the elastic force of the bullet pieces to hold them in elastic contact. A guide slope may be provided toward the locking step edge.

Alternatively, a printed wiring board may be used as the insulating plate, the connection terminal of the push switch may be inserted into the hole opened in the conductive land portion, and the connection terminal may be soldered to the conductive land portion.

[0007]

[Action]

 Since the push switch 4 attached to the base body 1 is sandwiched and supported by the surface of the base body 1 and the inner surface of the insulating plate 6 on both sides in the pushing operation direction, the switch 4 itself moves deliberately in the pushing operation direction. Never.

Another unnecessary movement of the push switch 4 is that the operating piece 4a is properly inserted into the hole 3 of the base body 1 and the connection terminal 5 projecting on the opposite side is engaged with the base body 1 by the locking bullet piece 2. It can be positioned by inserting it into the hole 6a of the insulating plate 6 fixed with 1,2, and the push switch 4 does not inadvertently move in any direction.

[0009]

【Example】

 Examples will be described with reference to the drawings. First, as shown in FIGS. 1 and 2, the basic structure of the present invention is such that a chamber is formed in a hole 3 of the base 1 between a pair of locking bullets 2, 2 integrally formed on the back surface of the plastic base 1. Insert the operation piece 4a of the push switch 4 along the inner piece 1a.

Then, the connecting terminals 5 projecting from the opposite surface of the operating piece 4a of the push switch 4 are inserted into the holes 6a of the insulating plate 6, and the projecting pieces 6b, 6b provided on both sides of the insulating plate 6 are attached to the above-mentioned engaging members. According to this invention, the push switch 4 is held between the insulating plate and the base body 1 by elastically pushing it against the elastic force of the bullet stop pieces 2 and 2 to engage the locking step edges 2a and 2a. Configure the push switch mounting device.

It should be noted that one of the pair of locking bullets 2, 2 may be an inelastic fixed piece having the locking shoulder 2a, and the locking shoulder 2a of the locking bullets 2, 2 may be one. As shown in FIG. 2, a guide inclined surface 2b having a dimensional difference d is provided inward so that the protruding piece 6b of the insulating plate 6 can be easily inserted between the locking step edges 2a, 2a. Good. Further, the lower side of the push switch 4 may be supported by the base piece 1a.

Further, as shown in FIG. 3, a printed wiring board is used as the insulating plate 6, and the connection terminal 5 of the push switch 4 is inserted into the hole 6a opened in the conductive land portion 6c. The push switch 4 and the printed wiring board 6 can be attached to the base 1 at the same time by connecting and fixing the soldering portion 6d to the 6c.

In order to use this, the operation between the connection terminals 5 and 5 can be controlled by operating the operation piece 4a as in the case of an ordinary push switch, and it can be used as a self-reset or push-push type switch.

[0014]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. The push switch 4 attached to the base body 1 is sandwiched and supported by the surface of the base body 1 and the inner surface of the insulating plate 6 on both sides in the pushing operation direction, so that the switch 4 itself moves deliberately in the pushing operation direction. The first effect is that the operation is reliable and agile because it does not exist.

Another useless movement of the push switch 4 is that the operating piece 4a is properly inserted into the hole 3 of the base body 1 and the connecting terminal 5 projecting on the opposite side is engaged with the base body 1 by the locking bullet piece 2. It can be positioned by inserting it into the hole 6a of the insulating plate 6 fixed with 1, 2, and the push switch 4 does not move in any direction. In addition to being able to protect the vehicle from external force, it has a second effect that it is strong against external disturbance even when the present device is mounted on a moving body such as a passenger car and used, and its fixed position can be maintained for a long period of time.

According to the second aspect, it becomes easy to mount the insulating plate.

According to the third aspect, the mounting of the printed wiring board can be easily and collectively performed.
