Description

[Detailed Description of the Invention] Industrial Application Field of the Invention The present invention keeps the operating state even if the force for pushing the push button mainly used for the control panel, operation panel, etc. is removed, and when it is pushed again, the original free state is restored. The present invention relates to an alternate push-button switch that returns to the above state, and a push-lock turn-type push button switch that returns to its original free state when the push button is pressed to keep the operating state and the push button is further rotated.

Prior Art When assembling the guide and the cam portion of the alternate type push button switch of the first invention, the one fixed to the jig with the slide pin inserted together with the push spring in the hole of the arm portion protruding on both sides of the stopper ring. Insert from the bottom of the case, then attach the cam to the guide, insert from both sides of the stopper ring from the bottom of the case, pull out the jig, and fix the cover to the case to assemble, but separate the guide and cam. Assembling in this state has the drawback that it is difficult to assemble due to manufacturing. The method of assembling the guide and slider of the push-lock turn type push button switch of the second invention is that the stopper ring and spring are fixed to the jig and the jig is attached to the case. Insert the guides inserted from the bottom and the sliders together with the springs from the bottom of the case to both sides of the stopper ring, remove the jig and remove the cover from the bottom of the case. Although it is fixed to the part and assembled, when the guide, spring, and slider are separate parts, the spring and slider must be inserted into the guide and assembled while pressing, which is a drawback that is difficult to assemble during manufacturing.

Problems to be Solved by the Invention With regard to the first invention, since the cam and the guide are separate parts,
Since the cam and guide must be inserted into the case during assembly, there is a problem in assembly workability. In the second invention, the guide, spring and slider are separate parts,
At the time of assembly, it was necessary to insert the spring and slider into the guide and then insert them into the case while holding them down, which was a problem in assembly workability.

The first invention is to push the cam into the guide and assemble the guide and the cam into one body so as to be inserted into the case as one component. The second invention is to integrate the slider with the spring into the guide by the pushing work. It is easy to assemble as a single part.

Effect of the Invention In the first invention, by assembling the guide and the cam into one part, the workability of inserting and assembling the guide into the case is facilitated. In the second invention, the spring and slider are assembled into the guide to form one part. This makes it easier to insert and assemble the guide into the case.

First Embodiment The first invention will be described with reference to FIGS. 1 to 5. 1 is a case that vertically penetrates, and 2 is an operation shaft that is inserted into the case 1 and is vertically movable. 3 is a stopper ring which is attached from below the case 1 and the lower end of the operating shaft 2 is fitted and fixed to the stopper ring 3, and 4 and 4 are slide pins together with the springs 5 and 5 of the arm portion projecting to both sides of the stopper ring 3. Inserted in the holes 6,6, 7 is a guide attached to the left and right of the stopper ring 3 of the case 1, 8 is a cam attached to the guide 6, and the tips of the slide pins 4,4 move into the cam groove 9 of the cam 8. Fitting is possible and 10 is fixed to the bottom of the case 1 with a cover. 11 is an indicator lamp and 12 is a return spring.

As shown in FIGS. 2 and 3, the cam 8 has guide protrusions 13, 13, 13, 13 above and below the cam 8 and a through hole 16 in the U-shaped intermediate portion of the guide 7. , Guide protrusions on the top and bottom inner surfaces of the through hole
There are sliding grooves 14, 14, 14, 14 on which 13, 13, 13, 13 slide, and guide protrusions 13, 13, 13, 13 are provided on the outside of the sliding grooves 14, 14, 14, 14. The push-in tapered portions 15, 15, 15, 15 that are fitted correspondingly are formed.

As shown in FIG. 4, the cam 8 is installed in the guide 7 by pushing it into the U-shaped portion of the guide 7, and the pushing taper portion 15,15,15,15 of the guide 7 is inserted into the guide protrusions 13,13 of the cam. 3, 13 and 13 are fitted and pushed in, and the cam 8 is press-fitted into the guide 7 as shown in FIG.
3,13,13 are mounted so as to be movable left and right in the sliding grooves 14,14,14,14 of the guide 7.

The method of assembling the guide 7 and the cam 8 into the case 1 will be explained. As shown in FIG. 5, the case where the stopper ring 3 is fitted with the springs 5 and 5 and the slide pins 4 and 4 is used as a case. Insert and mount from the bottom of 1, and then insert and mount the two left and right guides 7, 7 incorporating the cam 8 from the bottom side of the case 1,
After removing the jig, the cover 10 is fixed to the bottom of the case 1 to complete the assembly. Components other than the guide 7 and the cam 8 are inserted and mounted in the vertical direction of the case 1 in accordance with the assembly process.

The operation of the alternator type push button switch is such that the operation shaft 2 is lowered by the first push of the push button 17 and the slide pins 4, 4 move in the cam grooves 9, 9 of the cams 8, 8 to push the push button 17. The operating state is maintained even after removal, and the slide pins 4, 4 are pressed by the second push of the push button 17.
Moves in the cam grooves 9 and 9 to release the operating state.

The second invention will be described with reference to FIGS. 6 to 11. Reference numeral 30 denotes a case that penetrates vertically, and 31 denotes an operation shaft that is inserted into the case 1 from above and is vertically movable and rotatable. 32 is a stopper ring, and one end of the spring 33 is locked, the lower end of the operating shaft 31 is mounted and fixed to the stopper ring 32, and 34 is a guide, which is arranged on the left and right sides of the stopper ring 32, in which the spring 35 and the slider 36 are assembled. It is installed inside the case 30. The other end of the spring 33 is locked to the guide 34, 37 is a cover, 38 is an indicator lamp, and 43 is a return spring.

The spring 35 and the slider 36 are attached to the guide 34 by inserting the spring 35 into the hole 38 of the guide 34 as shown in FIG.
The slider 36 is integrally assembled to the guide 34 by pressing the slider 36 into the hole 38 by pressing. Hole in guide 34
When the slider 36 is pushed into the 38, the taper protrusions 39, 39 of the slider 36 are pressed against the taper portions 40, 40 of the holes 38 of the guide 34 and press-fitted, and the taper protrusions 39, 39 are shown in FIG. As shown in, the slider 36 is slidable in the grooves 41, 41 so that the slider 36 can slide in the grooves 41, 41, and the tapered protrusions 39, 39 are locked to the ends of the grooves 41, 41 so as not to come off. The method of assembling the push-lock turn push-button switch will be described with reference to FIG. 11. The stopper ring 32 and the spring 33 fixed to the jig are inserted and mounted from the bottom side of the case 30, and then the spring 35 and the slider 36 are assembled. Install the sliders 36, 36 on both sides of the stopper ring 32
Insert and mount from the bottom side of 0, remove the jig, fix the cover 37 to the case 1, and finish the assembly. Parts other than the stopper ring 32 and the guide 34 are inserted and mounted according to the assembly process.

The operation of the push-lock turn push-button switch is as follows:
The operation shaft 31 is lowered by pressing 42, and the stopper ring 32 is locked to the slider 36 to maintain the operation state. Then, the rotation of the push button 42 releases the locking state of the stopper ring 32 and the slider 36. It becomes the non-operating state of.

Effect of the Invention In the first invention, the guide protrusion of the cam is aligned with the pushing taper portion provided on the guide to integrate the cam and the guide by pushing, and in the second invention, the taper protrusion of the slider is fitted to the taper portion of the guide. The spring and the slider are integrally assembled to the guide by pushing in. Both the first and second inventions are easy to assemble by integrally assembling a plurality of parts to be mounted in the case. Workability in manufacturing can be improved.
