Description

[Detailed description of the invention] This invention relates to a switch device having a dustproof and waterproof structure.

As is well known, automatic soldering devices are often used these days to attach electronic components to printed wiring boards. In the case of such soldering, a cleaning liquid is generally used to clean solder gas and flux at the end of soldering.

By the way, in the case of a switch that is directly attached to a printed circuit board, flux or cleaning liquid may enter during the cleaning process through the gap between the connection terminal and the switchbox, or the gap between the operation part of the switch, the sleeve and the frame, or the frame and the switchbox. It is possible that Therefore, to prevent these from entering, the gap is filled with an adhesive or resin, or the entire switch is covered with a case made of, for example, a resin material to make it dustproof and waterproof. However, since the gap between the terminal and the box can be easily closed and the work is relatively simple, there is no problem, but the adhesive or resin material can be filled between the sleeve and the frame, and between the frame and the box. Otherwise, when coating, these may enter the switchbox and cause poor contact. Furthermore, it is not advisable to separately manufacture a case made of the resin material mentioned above to cover the entire switch in terms of manufacturing costs and assembly man-hours.

This idea was made based on the above circumstances, and by fixing the switchbox and frame, and the frame and sleeve through adhesive members cut into predetermined shapes, it is possible to obtain excellent dustproof and waterproof effects. It is an object of the present invention to provide a switch device which can be temporarily fixed during the assembly work of a switch and which can facilitate the assembly work.

An embodiment of this invention will be described below with reference to the drawings.

In FIG. 1, 11 is a switch box, and the bottom of this box 11 has a common terminal 1.
2. The first and second fixed terminals 13 and 14 are penetrated. The common terminal 12 and the first and second fixed terminals 13 and 14 are each formed by welding a resin material 15 to the outer surface of the box 11.
The gap between the box 11 and the box 11 is closed. A movable element 16, a movable contact piece 17, and springs 18 and 19 for biasing the movable contact piece 17 are provided in the box 11, and the movable element 16 is slid along the moderation part 20.

On the other hand, 21 is a frame attached to the opening of the box 11, and a sleeve 22 is fixed to this frame 21 by caulking. This sleeve 22
An operating element 23 is rotatably provided on the operating element 23, and an operating element 25 biased by a spring 24 is provided on the operating element 23 so as to be freely removable and removable. The distal end of the actuator 25 passes through the movable element 16 and comes into contact with the moderation part 20. Also, a stopper 2 is provided inside the sleeve 22.
6 and dustproof and waterproof packing 27 are provided.

Further, between the box 11 and the frame 21 and between the frame 21 and the sleeve 22, an adhesive member 28 is formed, which is cut out according to the opening circumferential surface of the box 11 and the through-hole circumferential surface of the frame 21, as shown in FIG. , 29 are provided. This adhesive member 28,
29, adhesives 32 and 33 are applied to both sides of a sheet-like material 31, such as rubber, as shown in FIG. 3a, for example.
These adhesives 32, 33 are provided with non-adhesive papers 34, 35, or, as shown in Figure b, non-adhesive papers 37, 38 are provided on both sides of the adhesive 36. Adhesive paper 34, 35, 3
7 and 38 are peeled off and used. That is, for example, when using an adhesive member as shown in FIG.
As shown in the figure, first, with the non-adhesive paper 38 peeled off, adhesive members 28 and 29 are adhered to the box 11 and the frame 21, respectively.
Peel off 7 and attach the frame 21 and sleeve 2 to the adhesive 36.
Glue 2. After this, the frame 21 and the sleeve are crimped and fixed to the box 11 or the frame 21, respectively.

According to the above configuration, the box 11 and the frame 21
The frame 21 and sleeve 22 are bonded together by adhesive members 28 and 29. Therefore,
After the sleeve 22 and frame 21 are fixed by caulking, excellent dustproof and waterproof effects can be obtained by using an adhesive or an adhesive and a sheet-like material such as rubber.

Further, the adhesive members 28 and 29 are attached to the box 11 in advance.
Since the mold is cut out according to the shape of the opening of the frame 21 or the peripheral surface of the through hole of the frame 21, the work is extremely simple, as it is only necessary to stick it. Further, since the adhesive members 28 and 29 are not in a liquid state as in the prior art, they do not penetrate into the box 11 during the bonding operation and cause poor contact.

In addition, since the box 11 and the frame 21 and the frame 21 and the sleeve 22 are temporarily bonded with adhesive members 28 and 29 before fixing by caulking,
This has the advantage that these members do not move unnecessarily during caulking and fixation, making the caulking work easier.

As described in detail above, according to this invention, it is possible to provide a switch device which not only provides excellent dustproof and waterproof effects, but also allows temporary fixing during switch assembly work and facilitates the assembly work.
