Description

[Detailed description of the invention] The present invention relates to a multiple switch, in which a plurality of operating handles 2 are attached to a cover 1 in parallel so as to be rotatable as a seesaw, and a switch mechanism is built in a body 3 that covers the cover 1. In a multiple switch that is operated by operating handles 2..., the outermost operating handle 2 among the plurality of operating handles 2... is rotated around the rotation center of seesaw rotation. In addition to providing a protruding shaft 4, a protruding shaft 5 and a bearing hole 6 are respectively formed on opposing surfaces of the adjacent operating handles 2, 2 at the center of rotation of the seesaw, and the protruding shaft 5 is rotated in the bearing hole 6. A plurality of operating handles 2 are fitted in the cover 1 so as to be freely movable, and the rotation shafts 4 are rotatably fitted into the bearing recesses 7, 7 formed on the inner surfaces of both sides of the cover 1. At the same time, the lower edge of temporary holding protrusions 9, 9 provided on the outer surface side of the operating handle 2 located at the outermost side is engaged with the locking protrusions 8, 8 protruding from the lower part of the inner surface of the cover 1. This is related to a continuous switch.

For conventional multiple switches of this type, cover 1
The structure for attaching a plurality of operating handles 2 to the machine was as shown in FIG. That is, rotation shafts 4, 4 are provided protrudingly on both sides of the operating handle 2, and the operating handles 2 are inserted into the openings 11 provided in the cover 1, respectively, and the operating handles 2 are inserted into the inner surfaces on both sides of the cover 1 or the partition wall 10.
A rotating shaft 4 is fitted into bearing recesses 7 provided on both sides of the shaft. However, in this case, the operating handles 2 are not held in any way by the cover 1, so when assembling the cover 1 onto the body 3, as shown in Fig. 2, hold the operating handles 2 with your fingers to prevent them from falling off. It is necessary to perform an operation for assembling the cover 1 to the body 3, and the assembling operation is time-consuming and tedious.

The present invention was developed in view of the above points, and there is no fear that the operating handle will fall off from the cover, and the cover can be easily attached to the body, and moreover, it can be used with multiple operating handles. The object is to provide a multiple switch that can be attached to the cover at the same time.

The present invention will be explained in detail below with reference to Examples. To explain a dual switch using two operating handles 2, one operating handle 2 has a rotating shaft 4 with a semicircular upper surface protruding from one side, and a rotating shaft 4 having a semicircular upper surface protruding from one side of the operating handle 2. The bearing hole 6 is recessed as shown in FIG. 5a. A similar rotating shaft 4 is provided on one side of the other operating handle 2, and a protruding shaft 5 is provided on the other surface of the operating handle 2, as shown in FIG. 5b. The cover 1 is formed into a box shape with an opening at the bottom, and the same number of openings 11 (in this case, two) as the operating handles 2 are provided on the top surface. The inner surfaces of both sides of the cover 1 are provided with bearing recesses 7 each having a semicircular upper surface as shown in FIG. 8 is protruding.

When attaching the operating handles 2 to the cover 1, fit the protruding shaft 5 into the bearing hole 6 to align the pair of operating handles 2, 2. In this state, the pair of operating handles 2, 2 are inserted into the openings 11, 11 from the bottom opening of the cover 1, respectively, and the rotation shafts 4, 4 of the operating handles 2, 2 are fitted into the bearing recesses 7, 7 of the cover 1, as shown in FIG. It's a lot of work. At this time, since the lower end edge of the rotating shaft 4 of the operating handle 2 protrudes as a temporary holding protrusion 9, it is locked to the locking protrusion 8 of the cover 1, and the operating handles 2, 2 are attached to the protruding shaft 5 and the bearing. It is integrated by fitting into the hole 6, and this locking protrusion 8,
By locking the temporary holding protrusions 9, 9 to the handles 8, the pair of operating handles 2, 2 are temporarily held on the cover 1 without fear of falling off from the cover 1. Therefore, when assembling the cover 1 into the body 3, the work can be carried out without having to use your fingers to prevent the operating handle 2 from falling off as shown in FIG. The operating handles 2, 2 are pivoted around a pivot shaft 4, a protruding shaft 5, a pivot shaft 4, and a bearing hole 6, respectively.

Inside the body 3 are a terminal plate 12, a fixed contact terminal block 14 having fixed contacts 13, and a locking spring 15.
A quick connection terminal consisting of a wire disconnection button 16 and a wire disconnection button 16 is attached as shown in FIG. A movable contact block 19 is provided which is biased by a spring 18. Reference numeral 20 denotes an assembly frame, which fixes the cover 1 to the body 3 by engaging the engagement ring portion 21 with the engagement protrusion 22 of the body 3. A transparent card cover 23 is fitted onto the protrusion 24 of the operating handle 2 to attach the cover 25. In the switch formed in this manner, the operating handle 2 is always pushed upward by the coil spring 18, and when the operating handle 2 is rotated in one direction, the movable contact block 19 is moved to one side by the reversing action of the coil spring 18. When the operating handle 2 is rotated in the opposite direction, the movable contact block 19 is tilted in the opposite direction and the movable contact 26 of the movable contact block 19 comes into contact with the fixed contact 13. Leave.

In the above embodiment, two operation handles 2, 2
As described above, when using three operation handles 2, the operation handle 2 located in the middle has a protruding shaft 5 and a bearing hole 6 on both sides, as shown in FIG.
and are connected to the operating handles 2, 2 on both sides. Further, in the above embodiment, the locking protrusion 8 was provided at the lower end of the bearing recess 7, and the lower edge of the rotating shaft 4 was made into the temporary holding protrusion 9. The temporary holding protrusion 9 is also provided at the locking protrusion 8.
Of course, it may also be provided at other locations on the side surface of the operating handle 2 correspondingly.

As described above, in the present invention, the temporary holding protrusion of the operating handle is locked to the locking protrusion of the cover when the plurality of operating handles are integrated by fitting the protruding shaft and the bearing hole. This allows multiple operating handles to be held within the cover without falling off, and it is possible to attach the cover to the body without having to press the operating handles with your fingers or the like when assembling the cover into the body. It can be easily installed. Moreover, each operating handle is connected by fitting the protruding shaft into the bearing hole, so there is no need to fit each operating handle into the cover one by one, and multiple operating handles can be fitted into the cover at the same time. It is something that can be done.
