Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a slide switch, and particularly to a slide switch having a structure that allows easy attachment of a switch case and selection of the attachment position.

(Summary of the invention) The present invention is a slide switch in which a cover is attached to a switch body to which a terminal with a fixed contact piece is fixed, and a handle connected to a movable contact piece is inserted and guided through a through hole at the upper end of the cover. By providing a screw groove on the outside of the cylindrical part of the cover for screwing into the nut, and by shaping the handle and the terminal so that they do not extend beyond the cylindrical part of the cover, the cover can function as a case. In addition to having a mounting function, it is possible to easily install and select the mounting position.

(Prior art) As shown in FIGS. 5 and 6, in conventional slide switches, the slide operation stalk of the handle 20 is long in the horizontal direction, and recent small switches tend to be light, thin, short, and small. Therefore, cover 2
The structure is such that the terminal board is fixed at the bent portions on both sides of 1. Therefore, the cover 21 is fixed to the mounting panel 22 using screws 23 at outer positions on both sides in the direction in which the handle is operated.

(Problem to be Solved by the Invention) According to the above-mentioned conventional technology, the mounting panel 22 has a long hole in the center and round holes on the left and right sides of the long hole, and the screws 23
The number of installation work increases because it is installed by screws.
In addition, the slide switch can be installed on the mounting panel 22.
Since it could only be done from the back side, the mounting direction was restricted. Furthermore, when selecting the mounting height of the switch, a special washer had to be used between the lower surface of the panel 22 and the cover 21, making it difficult to mount the switch at a desired height. .

In order to solve the above-mentioned problems, the present invention provides a slide switch in which the mounting position of the switch can be arbitrarily selected, the mounting work is easy, and the mounting can be done from either the front or back direction. The purpose is to

(Means for Solving the Problems) The slide switch of the present invention has a cover 14 attached to a switch body 3 to which a terminal 2 with a fixed contact piece 1 is fixed, and a movable contact in an upper end plate through hole 13 of the cover 14. In a slide switch in which a handle 8 connected to a piece 4 is pushed and guided, a screw groove 12 for screwing into the mounting nuts 15 and 17 is provided on the outside of the cylindrical part of the cover 14, and the handle 8 and the terminal 2 are connected to the cylindrical part of the cover 14. It is configured in a shape that does not protrude outside the cylinder from an extension of the outside of the shaped part.

(Function) According to the present invention, the substantially cylindrical cover 14 having the thread groove 12 on the outside is inserted into the opening of the mounting panel 18.
Insert the cylindrical part of the cover 14 from either the handle side or the terminal side, screw the round and hexagonal nuts 17 and 15 into the thread groove 12, and tighten the mounting panel 1 with both nuts.
Hold 8. At this time, both nuts can be fixed at any desired height of the thread groove 12.

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

Figure 1 is a front sectional view of the slide switch of the present invention, Figure 2 is an exploded perspective view of the slide switch of the present invention, Figure 3 is a plan view of the elastic body of the present invention, and Figure 4 is the slide switch of the present invention. FIG.

As is clear from these figures, the terminal 2 provided with the fixed contact piece 1 is attached to the switch body 3 which is open at the top.
Fixed to. Inside the opening of this switch body 3,
A movable contact 4, a slider 5 that drives the movable contact 4, a converter 7 that is integrally formed with the handle 8 and guides the slider 5 into the recess, and a converter 7 that presses the slider 5 toward the contact. A coil spring inserted into the recess is housed. The elastic body 11 has a hole 9 in the center that fits into the recess of the handle 8, and is provided with a plurality of concentric pleats 10, so that the elastic body 11 has an approximately disk shape as a whole.
The outer peripheral edge of the elastic body 11 is held between the inner surface of the cover and the upper edge of the switch body 3, as shown in FIG. The cover 14 is provided with a screw groove 12 over the required length on the outside of the cylindrical portion, a retaining portion having a through hole 13 corresponding to the operating stroke of the handle 8 is provided at the upper end, and a switch is inserted at the lower end. It is formed so that the main body 3 is caulked and fixed. A round nut 17, a rubber washer 16, and a hexagonal nut 15 for holding the mounting panel 18 are screwed into any thread groove 12 of the cover 14. By forming the elastic body 11 into a disk shape with a plurality of pleats 10, a sealing structure well adapted to the long operation stroke of the handle 8 in one direction can be achieved.

(Effects of the invention) As explained above in detail, according to the invention,
A slide switch is constructed by attaching a cover to a switch body to which a terminal with a fixed contact piece is fixed, and inserting and guiding a handle connected to a movable contact piece into a through hole in the upper end plate of the cover. is provided on the cylindrical outside of the cover, and the handle and terminal are shaped so that they do not protrude outside the cylinder from an extension of the cylindrical part of the cover. (1) When a conventional slide switch is installed on a panel, It was necessary to drill a total of three holes, a square hole in the center and a round hole on each side of the square hole, but with this invention, it is only necessary to drill one round hole, which reduces the number of man-hours required for installation. I'm done.

(2) Since the switch is mounted using a screw groove and a nut on the outside of the cover, the mounting height of the switch can be determined arbitrarily.
There is no need to use a special washer as in the past.

(3) Regarding the installation direction, as shown in Figures 5 and 6, conventional slide switches were limited to being installed only from the back side of the panel, but the switch of the present invention is installed so that the outside diameter of the cylindrical part of the cover passes through. If the hole is open, it can be inserted into the hole in the panel from the handle side.

(4) The mounting part of the switch is cylindrical, and
By providing screws on the outside, it is possible to maintain airtightness between the device panel and the switch mounting portion when the switch is mounted. Therefore, it is possible to obtain a panel waterproof type switch, which is not available in conventional slide switches.

(5) When an elastic body with a large number of concentric folds is placed between the handle and the cover in a sealed state, the folds will accommodate long left and right operation strokes, and the elastic body made of rubber etc. will not be damaged. . Furthermore, since the handle is shaped like a round bar, there is no gap between the hole in the elastic body and the handle, and the waterproof and dustproof function can be achieved over a long period of time.

It has the same effect.
