Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a push button switch, and particularly to a push button switch that facilitates mounting of a mounting case and fixing the mounting position.

(Summary of the invention) The present invention provides a push button switch with a mounting case, which includes a switch body case having a flange portion and a threaded portion, a detachably provided push button, and a female thread screwed into the threaded portion of the switch body case. By providing a mounting case with a flange having a bottom portion in which a hole is formed, and a nut that is screwed into the threaded portion and abuts the bottom portion to adjustably fix the mounting case to the switch body case. The mounting height of the mounting case can be adjusted, and it can be easily mounted without using special tools.

(Prior Art) As shown in FIG. 6, for example, in the mounting case of a conventional push button switch, the sleeve g of the switch body case a is inserted through the bottom opening of the mounting case b.
It was designed to be attached by clamping both sides near the opening with nuts e and f. Note that c is a push button and d is a flange of case b.

(Problems to be Solved by the Invention) According to the above-described prior art, it is possible to selectively attach the mounting case b according to the size of the push button. However, when mounting case b is attached to sleeve g, it is held between nuts e and f, so the mounting position of mounting case b relative to switch body case a is such that a special box spanner is used to tighten nuts e and f. This had the disadvantage of requiring a special work process.

Therefore, the present invention provides a push button switch in which a mounting case can be selected according to the size of the push button, the mounting position can be adjusted, and the mounting can be carried out without requiring special tools or work processes. The purpose is to

(Means for Solving the Problems) The push button switch of the present invention includes a switch body case 1 comprising a collar portion 5 and a threaded portion 6, a push button 3 provided detachably, and a screw on the switch body case 1. A mounting case 2 with a flange is provided with a bottom part 14 in which a female screw hole 15 is formed to be screwed into the threaded part 6, and the mounting case 2 is screwed into the threaded part 6 and abuts against the bottom part 14, and the mounting case 2 is attached to the switch body. A nut 11 is provided which is adjustable and fixed to the case 1.

(Function) According to the present invention, as described above, the threaded portion 6 of the switch body case 1 is attached to the bottom portion 14 of the mounting case 2.
Since the nut 11 is screwed into the threaded part 6 and abuts on the bottom part 14, the mounting case 2 is adjustable with respect to the switch body case 1. can do.

Therefore, the mounting case can be selected according to the size of the push button, the mounting position can be adjusted, and the push button can be mounted without requiring any special tools or work steps.

Further, the height of the mounting case 2 relative to the switch main body case 1 can be adjusted as desired.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

Figure 1 is a sectional view of the main parts of the push button switch of the present invention.
Fig. 2 is an exploded perspective view of the push button switch of the invention, Fig. 3 is a sectional view of the mounting case of the invention, Fig. 4 is a perspective view showing a modified embodiment of the mounting case of the invention, and Fig. 5 is the main body of the push button switch. FIG. 7 is a sectional view of main parts showing another embodiment of the invention.

As shown in these figures, the basic model of the push button switch of the present invention consists of a switch body case 1, a push button 3,
It has a drive mechanism including a plunger 4 and the like operated by a push button 3 and a terminal 7.

The switch body case 1 includes a flange 5 that forms a step for locking onto a panel, etc., a substantially cylindrical threaded part 6 with a smaller outer diameter than the flange 5, and a nut 11 that is screwed into the threaded part 6. and has. In the drive mechanism, the plunger 4 is connected to a contact portion (not shown) in the switch body case 1, and a portion of the drive mechanism transmits driving force to the contact portion. The push button 3 can be replaced with buttons of various sizes, and is detachably attached to the plunger 4. Further, 12 is a light emitter that illuminates the push button 3. Although such a basic type push button switch is a single switch in itself, the present invention further provides a mounting case 2 to the basic type push button switch. As shown in FIG. 3, the mounting case 2 has a substantially U-shaped cross section, and has a mounting flange 9 facing outward at the top and a flange 9 connected to the flange 9 and having a smaller diameter than the flange 9. Cylindrical mounting screw part 10 and switch body case 1
It has a circular hole 13 having a female threaded hole 15 which is screwed into the threaded part 6 of the screw, and also has a bottom part 14 on which the nut 11 comes into contact. When installing this mounting case 2 to the switch main body case 1, use the hole 8 of the mounting case 2.
, screw the threaded part 6 of the switch body case 1 into the circular hole 13 having the female threaded hole 15, and then screw the nut 1 into the bottom part 14 with the mounting case 2 in a fixed position.
Tighten and secure.

If it becomes necessary to replace the push button 3 with one of a different size, loosen the nut 11, remove the mounting case 2, and use the same mounting method described above to install the push button of the appropriate size and the mounting that matches that size. Try reinstalling the case.

Further, the mounting case 2 can also be adapted to a square push button by providing a square collar part 16 and a threaded part 17 continuous thereto, as shown in a modified example in FIG. In this way, mounting case 2
The shape of the push button 3 can be appropriately selected according to the shape of the push button 3.

Furthermore, if a waterproof function is required, a waterproof cover such as a rubber gasket 18 may be attached to the mounting case 2 and the plunger 4 as mounting portions at both ends, as shown in FIG.

It should be noted that the present invention is not limited to the above embodiments, and various modifications can be made based on the spirit of the present invention, and these are not excluded from the scope of the present invention.

(Effects of the invention) As explained above in detail, according to the invention,
A female threaded hole is formed at the bottom of the mounting case, the threaded part of the switch body case is screwed into the hole, and the screw is tightened and fixed with a nut, so that the position of the mounting case can be adjusted freely. In addition, there is no need for difficult internal installation work using special tools as in the past, and work can be easily done from the outside of the switch.Furthermore, no special tools or fasteners are required to install the mounting case, and the switch is a basic push button switch. Ordinary nuts can be used.

Furthermore, it is possible to select push buttons and mounting cases of various sizes, and to easily attach and detach them.

Furthermore, by providing a waterproof cover between the mounting case and the plunger, a sufficient waterproof effect can be achieved. Furthermore, it is extremely easy to change a push button switch that is not waterproof to a waterproof type.
