〔Example〕

Embodiments of the present invention will be described in detail and specifically below based on the drawings.

1 to 3 show an embodiment of the present invention. In this example, the present invention is applied to a push button switch, and FIG. 1 shows its assembled state, and FIGS. 2 and 3 show its mounting structure on the printed circuit board on the switch section side. In FIG. 1, there is no particular difference in the mounting structure of the operating section 40 constituting the push-button switch output to the panel 9 from the example shown in FIG. 6, so a description thereof will be omitted. Reference numeral 70 denotes a switch section attached to the side of the printed circuit board 12. As shown in this figure, the switch section 70 includes two switch elements 11 and a holder 7 that houses them and is firmly attached to the printed circuit board 12.
1.

The assembly and configuration will be further explained with reference to FIGS. 2 and 3. As shown in FIGS. 2 and 3, the holder 7I has a wall portion 71A surrounding the four sides, and a switch element locking hole 71B formed in the opposing wall portions. The switch element 11 should be maintained in that state when the switch element 11 is inserted from below the holder 71 in FIG. Element top surface 1
1C, and a switch element fixing wall 71C that is in elastic pressure contact with the switch element fixing wall 71C.
Further, a branched locking leg portion 710 is provided in a protruding manner.

Reference numerals 12A and 12B designate a pair of element through holes and a holder mounting hole that are bored in the printed circuit board 12, respectively. Therefore, the switch section 70 is connected to the printed circuit board 12.
To fix the switching elements 11 above, each switch element 11 is first inserted from below the holder 71 as shown in FIG. 2, and the upper surface 11C of the element is pressed against the lower surface of the fixed wall 71C. Then, using the elasticity of the fixed wall 71C, the switch element l
By engaging the engagement protrusion 11B in the locking hole 71B of the wall portion 71A, the switch element 11 can be stably held in the holder 71.

Therefore, next, the locking legs 71D of the holder 71 to which the switch elements 11 are fixed in this manner are press-fitted into the holder mounting holes 12B of the printed circuit board 12, and the lead terminals lIA of each switch element 11 are inserted. By inserting the holder 71 into the through hole 12A, the holder 71 can be fixed to the printed circuit board 12 using the bifurcated elasticity of the locking leg 710. In this state, the lower surface of the wall portion 71A of the holder 71 is in contact with the printed circuit board 12, and the holder 71 is positioned against the printed circuit board 12 due to the tapered shape of the locking leg portion 71D and the elasticity of the bifurcated parts. Since the switch section 70 acts so as to be biased toward
The operating stroke between the and the operating section 40 can be set accurately. Therefore, after this, the lead terminal 11
It is sufficient to solder A to the printed circuit board 12 from the back side.

FIG. 4 shows an example in which the operation panel 9 to which the operation section 40 is fixed is fixed by the spacing piece 140 to the printed circuit board 12 on which the switch section 70 is attached as described above. Here, the spacing piece 140 has a flat head 140A formed at one end thereof, and the size of the lower neck 140B is formed to match the predetermined spacing between the panel 9 and the substrate 12. In addition, a backing 141 for waterproofing and oil-proofing is interposed between the lower surface side of the flat head 140A and the panel 9, and a screw hole is provided on the surface of the spacing piece 140 that contacts the printed circuit board 12. 140G is drilled. 142 is a nut member for fixing the flat head 140A side of the spacing piece 140 to the panel 9.

Therefore, the spacer piece 140 is inserted into the spacer piece attachment hole 9B of the operation panel 9 to which the operation unit 40 is attached via the backing 141.
After inserting the lower neck part 140B of the PC board, fix the flat head part 140A of the spacer piece to the panel 9 with the nut member 142, bring the end of the lower neck part 140B into contact with the printed circuit board 12, and then screw the flat head screw 143 onto the printed circuit board 12. Screw hole 140 from the bottom side of 12
The whole can be integrated by screwing into C.

FIG. 5 shows an example in which the present invention is applied to a lighting switch. The lighting switch 200 is separated into an operating section 40 and a switch section 70, and the operating section 4
0 is attached to the operation panel 9, and the switch section 70 is attached to the printed circuit board 12. 41 is the hollow part 4 of the operation part 40
It is a light source lamp provided at 0A, and two contact plates 42A and 42B connected to the lamp 41 are connected to the contact plate holding member 4.
3 is integrally molded.

On the other hand, in the switch section 70, 72 is the lead terminal 11.
73 is a contact pin whose tip portion protrudes upward, and 74 is a spring provided between the contact pin 73 and the terminal member 72 to bias the contact pin 73 upward. be. Further, a locking leg portion 710 having elasticity is provided to protrude from the lower surface side of the holder 71 of the switch portion 70 .

Now, the switch section 70 having such a configuration is fixed on the printed circuit board 12, and the panel 9 on which the operating section 40 is attached and the printed circuit board 12 are connected by the spacer 14 according to the example shown in FIG.
When assembled together via the contact pin 74, the contact pin 73 is brought into pressure contact with the contact plates 42A and 42B by the spring 74, so that a stable lamp lighting state can be maintained.

Next, another embodiment of the present invention will be described with reference to FIG. Here, the pushbutton switch is based on the embodiments described above, and the one shown here is an example without a light source lamp for illumination. In addition, the world is an illuminated indicator lamp, and when only an indication is performed without being combined with a switch means like the aforementioned illuminated switch, the fifth
If the configuration shown in the figure is adopted, there will be a large number of unnecessary parts, resulting in an increase in cost.

Therefore, in this embodiment, first, the light source lamp 41 is firmly held on the fixing base 21 on the printed circuit board 12, and the hood 22 with lens is fitted into the mounting hole 9B of the operation panel 9 from above. Then, by tightening the cylindrical nut member 23 to the threaded portion 22A of the lens hood 22, a display section is constructed on the operation panel 9 side. Note that the lower half of the nut member 23 has a sufficiently wide inner cavity so that the light source lamp 4I can
is accommodated in the inner cavity with plenty of room, and also serves as a hood. 24 is a backing for keeping the space between the hood 22 and the operation panel 9 liquid-tight.

Furthermore, in FIG. 6, 240 is a spacing piece. The spacing piece 240 shown in this example has a screw hole 24 provided at its panel side end.
It is coupled to the panel 9 by screwing the protruding screw 9C on the operation panel 9 side into 0A. Note that the protruding screw 9C is fixed at a predetermined position on the back side of the operation panel 9 by, for example, welding or the like. 1
The operation panel 9 and the printed circuit board 12 are fixed together by screwing together the screws 143 from the lower surface side of the panel 2.

120 is a printed circuit board 12 on the bottom side of the printed circuit board 12.
121 is a second spacing piece, 122 is a screw for fixing the reinforcing plate 120 to the printed circuit board 12 via the spacing piece 121, 123 is a hole for screw operation, By providing such a hole 123 directly below the fixed position of the spacer piece 240 between the panel and the board, a tool such as a screwdriver can be inserted through this hole 123 when removing the printed circuit board 12 from the operation panel 9 side. .

The reason why the above-mentioned reinforcing plate 120 is provided is that the printed circuit board 12 originally lacks rigidity, so it cannot be bent against the reaction force of switch operation or the reaction force generated between the switch section 70 and the operation section 40. This is because there is a risk of operational errors such as insufficient stroke due to this. Although it is conceivable to increase the number of spacing pieces 240, this would not only increase the number of parts, but also require more time and effort to assemble, and would also restrict the arrangement of the operation section and display section on the operation panel 9. This is not desirable.

Figures 7A and 7B show the configuration of a push button switch previously proposed by the present inventors and disclosed in Japanese Utility Model Application Publication No. 62-37130. Unlike the one published in the above-mentioned Publication No. 1-2545J1, as shown in Fig. 7, the push button 4 is
A protective cover 30 for preventing erroneous operation is provided on A itself so that it can be opened and closed.

Therefore, there is no need to change the distance between the operation panel 9 and the printed circuit board 12, and furthermore, it can be retrofitted, and it can be suitably employed in the operation device configured according to the present invention. In addition, in FIG. 7A and FIG. 7B, 4B and 4C are the outer hinge part and the inner hinge part respectively erected from the push button 4A, and 30A is the cover 3.
The support arm on the 0 side, 30B is a pin support, and 31 is a torsion coil spring. FIG. 8 is an explanatory diagram of the process of attaching the protective cover 30 to the push button 4A, and from the state shown in (A), attach the pin 30C provided on the support arm 30A of the cover 30 to the outer hinge portion 4C of the push button 4A. By fitting them together in the direction of the arrow, the attached state shown in (B) can be achieved.

FIGS. 10 and 11 show still another embodiment of the present invention in an assembled state and a disassembled state before assembly, respectively. In these figures, 51 is a second panel (hereinafter referred to as a dummy panel) provided on the back side of the operation panel 9 so as to overlap this.

In this dummy panel 51, a hole 51A of the same size as the hole 9A provided in the operation panel 9 is bored at the same position in order to fix each operation part 40 with the upper nut member lO passed through it. A fixing screw hole 53 is provided vertically at the mounting position of the joint piece 140. 54 is a screw hole provided on the printed circuit board 12 side of the joint piece 140.

Therefore, in the assembly structure of the separate type switch configured in this way, first, the operation panel 19 and the dummy panel 51 are correctly overlapped, and then the operation section 40 is inserted into the operation section mounting holes 9A and 51A of both. Furthermore, a backing (not shown) is provided between them, and the nut member 10 is connected to the operating section 4.
1. Screw it around the periphery of 0 to obtain the state shown in FIG. 11. At the same time, a printed circuit board 12 with a contact portion 70 fixed by soldering or the like is prepared. Then, the screw hole 5 of the dummy panel 51
3 is screwed onto the threaded portion 140A of the joint piece 140 to fix it. In this case, since the screw holes 53 of the dummy panel 51 can be correctly drilled vertically in advance, the indirect piece 140
will not be installed at an angle. After the installation of the indirect piece 140 is completed in this way, the printed circuit board 1 is then attached.
2 can be properly positioned from above, and the printed circuit board 12 can be fixed to the joint piece 140 using the screws 143.

FIG. 12 shows, as a comparative example, an example in which the indirect piece 140 is directly screwed onto the operation panel 9 without using a dummy panel. If the operation panel 9 has a sufficient thickness for tapping screws, it is also possible to directly drill the screw holes 53 in the operation panel 9 in this way. 140 threaded part 140A
is exposed. Therefore, we have removed the operation panel 9 so that it does not look unsightly.
Problems remain, such as the need to refinish the surface and the sealing performance being impaired, which requires countermeasures.

〔Effect of the invention〕

As described above, according to the present invention, the holder for storing and holding the switch element of the operating device is formed of an elastic body, and the elasticity allows the switch element to be engaged and positioned within the holder, and the lower surface of the holder A locking leg is provided protruding from the
By press-fitting the locking legs into the mounting holes provided on the printed circuit board, the elasticity of the locking legs allows the switch section to be crimped onto the printed circuit board via the holder, so even if the switch element is soldered to the printed circuit board, The switch part is held in close contact with the printed circuit board without floating up from the printed circuit board, and it is possible to prevent the switch element and the printed circuit board from being damaged due to a pressing operation by the operating section.

Also, with the lower surface of the head of the spacing piece pressed against the upper surface of the panel, tighten the head to the panel with a nut member, and then fix with screws while the end of the columnar section is in contact with the printed circuit board. Therefore, it is possible to sufficiently withstand the tensile stress generated in the spacer piece during operation, and to maintain a stable operation stroke between the operation section and the switch section.

Furthermore, when an illuminated switch is provided as an operating device, the light source and a contact part for connecting the light source to the switch section are fixedly provided in the operating section, and connected to the terminal piece on the switch section side in an assembled state. Since the light source is elastically pressed against the contact pin, the light source can be positioned at a position where uniform illumination can be obtained, and there is no risk of contact failure even under severe vibrations.

Furthermore, when the operation section is provided with a display section using a light source, the lens hood is fixed with a nut member from the back side of the operation panel, and a hollow section is provided in the extending section of the nut member, and the board side side is provided in this hollow section. By accommodating a fixed light source, it is possible to provide an indicator light that requires fewer parts and is easy to assemble.

Further, by reinforcing the printed circuit board with a reinforcing plate, the rigidity of the printed circuit board can be ensured, and operability can be ensured.

Furthermore, by screwing the spacing piece to the second panel provided overlapping the operation panel,
The spacing piece can be installed correctly at right angles to the operation panel, allowing a predetermined distance to be stably maintained between the operation panel and the printed circuit board, and also preventing deviations in the relative positions of the operation part and the contact part. This has the effect of preventing the occurrence of.
