Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a locking part 3 on the side surface of a switch body 2 whose upper surface is covered with a cover 1 and which is attached to a printed circuit board, and a handle shaft 4 is rotatably supported in the center of the cover 1. A boss 5 is provided to protrude, and the tip of the handle shaft 4 is made to protrude from the boss 5, and locked parts 9 are provided on the legs 8 on both sides of the mounting bracket 7 having the central hole 6.
Hole 21 of plate 20 covering printed circuit board 19
Insert the leg 8 of the mounting bracket 7 into the locking part 9 to removably lock the locked part 9 to the locking part 3, and press the mounting piece 16 of the mounting bracket 7 against the surface of the plate 20, so that the tip of the handle shaft 4 Positioned in the center hole 6, mounting bracket 7
This is a switch in which a handle shaft 4 is inserted into a shaft insertion hole 11 on the lower surface of a handle 10 rotatably attached to the switch body, and its purpose is to prevent dirt from entering the inside of the switch body. It is an object of the present invention to provide a switch in which the handle can be easily attached to the switch body.

The present invention will be explained in detail below with reference to Examples. In the figure, 2 is the main body of the switch, and its upper surface is covered with a cover 1. A boss 5 for rotatably supporting the handle shaft 4 is protruded from the center of the cover 1, and the tip of the handle shaft 4 extends from the boss 5. It's made to stick out. In the figure, reference numeral 12 denotes a convex portion for attaching the cover, into which the hole 13 of the cover 1 is engaged. A locking part 3 is provided on the side of the switch body 2.
This locking portion 3 has a tapered shape in which the length of the projection becomes longer toward the bottom. 7 in the figure is a mounting bracket, and in the embodiment shown in the figure, there are two L-shaped plates 7.
a are connected by two connecting plates 7b.
A central hole 6 is bored in the center of the mounting bracket 7, and legs 8 hang downwardly facing each other on both sides of the center hole 6 on the lower surface of the mounting bracket 7. is provided with a hole, and this hole serves as a locked portion 9. Handle support pieces 14 protrude upward from both front and rear sides of the central hole 6, and a shaft hole 15 is bored in the upper part of the handle support piece 14. In the figure, 16 is a mounting piece. 10 in the diagram
is a handle, with rotating shafts 17 on both sides of the center lower part.
The outer end surface of the rotary shaft 17 has a longer protruding length toward the upper end and a shorter protruding length toward the lower end. Further, a shaft insertion hole 11 is bored in the lower surface of the handle 10. In the figure, reference numeral 18 indicates a handle angle regulating shoulder provided on the mounting bracket 7. However, the switch body 2 is attached to a printed circuit board 19, while the handle 10 is attached to the mounting bracket 7 with the rotating shaft 17 removably supported in the shaft hole 15. The legs 8 of the mounting bracket 7 are inserted through the holes 21 of the plate 20, the locked portion 9 is removably locked to the locking portion 3, and the mounting piece 16 is pressed against the plate 20. At this time, the handle shaft 4 is inserted into the shaft insertion hole 11 on the lower surface of the handle 10, the boss 5 is further covered by the handle 10, and the mounting bracket 7 is inserted.
The connecting plate 7b collides with the upper surface of the cover 1, and the downward movement of the mounting bracket 7 is blocked. The boss 5 is inserted into the central hole 6. By the way, when removing the handle 10 from the mounting bracket 7, it is necessary to spread out the space between the handle support pieces 14, and when removing the mounting bracket 7, pry a screwdriver or the like between the switch body 2 and the leg 8. It is something you put in and take out. In the figure, reference numeral 22 denotes a spring piece, which is brought into elastic contact with the hole 21 of the plate 20.

In the present invention, a locking part is provided on the side surface of the switch body attached to the printed circuit board as described above, and a locked part is provided on the legs on both sides of the mounting bracket to which the handle is attached, so as to cover the printed circuit board. Insert the legs of the mounting bracket into the holes of the plate, removably lock the locked part to the locking part, press the mounting piece of the mounting bracket against the surface of the plate, and insert the tip of the handle shaft into the center hole. The handle shaft is inserted into the shaft insertion hole on the bottom of the handle which is rotatably attached to the mounting bracket.When installing the handle in conjunction with the handle shaft of the switch block body mounted on the printed circuit board, the plate Simply insert the legs of the mounting bracket through the hole, lock the locked part to the locking part, press the mounting bracket against the surface of the mounting plate, and insert the handle shaft into the shaft insertion hole to insert screws, etc. The mounting bracket with the handle attached can be attached to the switch block body and plate without using it. In addition, even if a large external force or abnormal force is applied to the handle, the force will mainly be applied to the plate via the mounting bracket, and will not be applied to the printed circuit board to which the switch body is attached. The switch body and the printed circuit board to which the switch body is attached can be protected by being received by the plate through the switch body. Moreover, the mounting bracket and the handle attached to the mounting bracket can prevent dust from entering from the front side of the plate into the inside where the switch body is located (the back side of the plate), and on top of that, the switch body is covered with a cover. Dust does not enter the switch body, and a boss that rotatably supports the handle shaft is protruded from the center of the cover, the tip of the handle shaft protrudes from the boss, and the tip of the handle shaft is positioned in the center hole. Since the handle shaft is inserted into the shaft insertion hole on the bottom of the handle, the only gap between the handle shaft and the boss is covered by the shaft insertion hole, and the boss is also covered by the handle, resulting in waste. This has the advantage of preventing the intrusion of dust and providing sufficient dustproof properties.
