Description

[Detailed description of the invention] The present invention relates to a multiple push switch interlocking mechanism, and its purpose is to mount a plurality of push switches on a mounting frame at close intervals, and to ensure reliable interlocking operation between each push switch. It is about providing.

To explain the interlocking mechanism of a conventional multiple push switch, the push switch 1 is inserted into a notch 11a of a substantially U-shaped mounting frame 11, and a protrusion 11b
It can be attached by caulking. The operating rod 2 of each push switch 1 is provided with a cam portion 3 for interlocking operation. Reference numeral 12 denotes an interlocking cam plate made of a metal plate, and the interlocking cam plate 12 is provided with a protrusion 12a that contacts the cam portion 3 of the operating rod 2 and a protrusion 12b that locks one end of the biasing spring 13. The interlocking cam plate 12 is located within the mounting frame 11, and as shown in FIG.
A biasing spring 13 is interposed between it and b. In other words, since the biasing spring 13 is located between the push switches 1, 1, the push switches 1, 1
The drawback was that the space between them could not be made smaller.

The present invention was developed in view of the above-mentioned drawbacks, and the above-mentioned problem is solved by not disposing the biasing spring for biasing the interlocking cam plate between the push switches.

One embodiment of the present invention will be described below with reference to the drawings.Since the structure of the push switch is the same as that of the conventional example (see FIG. 1), the explanation will be omitted. 4 is a mounting frame formed by punching and bending a metal plate;
A notch 4a for housing the push switch 1 and a mounting piece 4b for attaching and fixing the push switch 1 are formed in the. A semicircular notch is provided near the tip of the mounting piece 4b, and the push switch 1 is housed in the mounting frame 4.
The tip of b is made easier to bend when caulking.
Reference numeral 5 denotes an interlocking cam plate formed by punching out a metal plate and performing barrel finishing. A protrusion 5b is provided for locking one end of the protrusion 5b. Reference numeral 7 denotes a spring receiving member molded from synthetic resin, and the spring receiving member 7 is U-shaped as shown in FIG. 3 and has two arm portions 7a, 7a.
and a protrusion 7b that locks one end of the biasing spring 6. A locking protrusion 7c is formed at the tip of the arm portion 7a, which fits into a notch 4c formed near the bottom of the mounting frame 4, and a spring receiving member is provided at the bottom of the mounting frame 4. 7 is arranged.

Next, to briefly explain the assembly of the multiple push switch interlocking mechanism of the present invention, first, the spring receiving member 7 is inserted into the bottom of the mounting frame 4, and the locking protrusion 7c of the arm portion 7a is fitted into the notch groove 4c. By doing this, the mounting frame 4
Position the spring receiving member 7. Then, one end of the biasing spring 6 is locked to the protrusion 7b of the spring receiving member 7, and the other end is fixed to the protrusion 7b of the interlocking cam plate 5.
The interlocking cam plate 4 is inserted and arranged at the bottom of the mounting frame 4 so as to engage b. Next, the push switch 1 is inserted into the notch 4a of the mounting frame 4, and after a predetermined number of insertions, the tips of the mounting pieces 4b are crimped at the semicircular notches using a crimping jig. In this case, one mounting piece 4b holds the cases 1a, 1a of the push switches 1, 1 located on both sides thereof. In the multiple push switch assembled in this manner, the protruding piece 5a of the interlocking cam plate 5 is in contact with the cam portion 3 of the operating rod 2 of the push switch 1, as shown in FIG. 4A.

Next, to explain the interlocking operation in the interlocking mechanism of the multiple push switch of the present invention, in the state shown in FIG. 4A, the operating rod B is pressed in the direction of the arrow It is in a state where it is engaged with and held by part 3. When operating rod A is pushed in the direction of arrow X from this state, the interlocking cam plate 5 is moved to the right by the cam portion of operating rod A against the force of biasing spring 6, and operating rod B is released. At the same time, the operating rod A is now locked by the protruding piece 5a of the interlocking cam plate 5. As explained above, each operating lever performs a mutually interlocking operation.

As mentioned above, the multiple push switch of the present invention has a spring receiving member and an interlocking cam plate disposed at the bottom of the approximately U-shaped mounting frame, and a biasing spring is placed between the spring receiving member and the interlocking cam plate. This eliminates the need to place biasing springs between the push switches as in the past, allowing each push switch to be mounted on the mounting frame with closer spacing, resulting in a more compact multiple push switch that performs reliable interlocking operations. It has remarkable practical effects.
