Description

[Detailed description of the invention] The present invention is a light-emitting switch that can quickly, accurately, and reliably insert and remove the light-emitting part when replacing the light-emitting element of the light-emitting switch or replacing the name plate, etc. It is about the mechanism.

Illuminated switches allow you to safely and easily replace the light-emitting element, name plate, and filter without stopping the external device electrically connected to the switch, even if the device is in operation. must be able to Conventionally, the replacement operation was performed by first releasing the light-emitting part provided at the front end of the light-emitting switch and the board on which the light-emitting element is mounted from the case of the light-emitting switch, and then removing it from the case of the light-emitting switch. was. When re-inserting after this replacement operation, damage to the illuminated switch components due to such insertion etc. is prevented,
Since the mounting is performed at an accurate position, the hole E' in the rectangular frame E provided at the center of the substrate H on which the light emitting element D is mounted on the top surface, as shown in FIG.
For example, as shown in FIG. 1b, one end of the plunger C is fixed to the illumination part A, and a protruding pin B is inserted into the other end of the plunger C, and as shown in FIG. By being rotated 90 degrees, the short side E' of the piece E comes into contact with the claws F attached to both sides of the piece E, and the end F' of the claw F protrudes from the board H, and the end of the claw F There is a means for fixing the components of the illuminated switch to the case of the illuminated switch by engaging the portion F' with the case of the illuminated switch (not shown) while applying the biasing force of the coil spring G.

The conventional illuminated switch described above has a complicated structure because it has a fixing mechanism consisting of a rotating top E, a coil spring G, a claw F, etc. on the board H, and has a large number of components, making it difficult to assemble. This had the disadvantage of being time-consuming and expensive. The present invention was devised to eliminate these drawbacks, and its purpose is to make it easy to replace light emitting elements, name plates, and filters with a simple mechanical configuration, and to prevent mating caused by incorrect insertion. It is an object of the present invention to provide an illuminated switch which has usefulness such as being able to prevent damage to parts.

The structure of the present invention is that an illuminated switch has an illuminating section provided in the case of the illuminated switch at the front end of the case and can be pushed back and forth to return, and one end fixed to the illuminating section and a pin at the other end midway. A plunger with a projecting surface, a board with a light emitting element mounted on the front surface and a hole for inserting the plunger, and a switch unit fixed to the rear end of the case are housed. In an illuminated switch in which the switch unit is switched by pressing and returning, the board is made up of at least two layers facing each other at a distance, and the rear part of the board made of the at least two layers is The substrate is provided with a pin hole for the pin insertion, which is continuous with the hole for the plunger insertion, and a convex portion having restoring elasticity is provided on at least one of the opposing surfaces of the substrate made of at least two layers. is formed, the distance between the top of the convex portion and the other opposing surface is smaller than the diameter of the pin, and the pin is removably engaged between the convex portions by rotation of the plunger. This invention relates to an illuminated switch, which is characterized by an illuminated switch, and will be described below based on an embodiment shown in the drawings. FIG. 2 shows the assembled state of the illuminated switch of the present invention. In the figure, reference numeral 1 denotes an illumination part that is provided at the front end of the case 2, houses a name plate, a filter, etc., and can be pushed back and forth in the case 2 to return to its original position. 2, and this engagement is released by pulling out the front end of the illumination part 1 by hand or the like. 2 is a case, 3 is a switch unit, 4 is a contact, 5 is a plug, and 7 is a plunger. As shown in FIG. 3, the plunger 7 has one end fixed to the center of the bottom surface of the reflective case 8 that constitutes the illumination part of the illuminated switch, and a pin 12 protruding from the middle of the other end. The switch unit 3 is brought into contact with the switch in the unit 3 so as to be able to be pushed and returned, and the switch unit 3 is switched by the return of the plunger 7, that is, the return of the illumination part.

In addition, in the middle part of the case 2, a light emitting element 14 is mounted on the front surface of a substrate consisting of at least two layers facing each other at a distance, and a hole 6 for inserting the plunger 7 is provided. The front board 9 and the rear board 10, which is provided with a pin hole 11 for inserting a pin 12, which is continuous with the hole 6 for inserting the plunger 7, are integrated with a short distance therebetween. Plugs 5 are fixedly installed on both sides of the back side of the board 9, and the plug insertion part 17 of the plug 5 is removably engaged with the contact 4 fixed to the rear part of the case 2, thereby electrically connecting the board 9. and is attached to the case. In addition, plug 5
The plug terminal 16 is connected to the light emitting element 14 on the front board 9.
An electrical connection is made in a fixed manner with a conductive path 15 that conducts electricity.

As shown in FIG. 4, a convex portion 13a having restoring elasticity made of synthetic resin or the like is formed between the two layers of substrates 9 and 10, and a pin 12 can be freely inserted and removed between the convex portions 13a. recess 1 that is firmly and firmly engaged with the
3b is formed. Naturally, this convex portion 13
The distance between the top 13a' of the plate 13a and the back surface 9a of the substrate 9 is smaller than the diameter of the pin 12 of the plunger 7. 4 and 5, the convex portion 13a and the concave portion 13b are formed on the front surface 10a of the rear substrate 10, but they are formed on the front surface 10a of the rear substrate 9.
It may be formed on the back surface 9a, or even on both the back surface 9a and the front surface 10a.

In the above configuration, for the completed illuminated switch as shown in FIG. 11, the pin 12 is brought into contact with the back surface 9a of the front board, and in this state, the fitting between the plug insertion part 17 and the contact 4 is released, and the illumination part 1 is pulled out further forward. Lighting part 1 and two-layer substrate 9, 1
The case 0, etc. can be easily separated from the case 2, and the light emitting element, name plate, and filter can be replaced.

In addition, when re-inserting the illumination unit 1 and the two-layer substrates 9, 10, etc. into the case 2 after the replacement operation, pin 1
2 is engaged between the convex portions 13a, that is, in the concave portions 13b, that is, in a state where unstable tilting, unnecessary rotation, rocking, etc. of the substrates 9, 10, etc. are prevented, and the illumination portion 1 is inserted, and the pin 12 is brought into contact with the front surface 10a of the rear board 10 and pressed, so that the plug insertion part 17 and the contact 4 are accurately fitted without any mis-insertion, and then the illumination part 1 is rotated and the pin 12 is This can be easily done by inserting the pin into the hole 11 and pushing the illumination part 1 to a predetermined position.

However, according to the present invention, when replacing light emitting elements, name plates, and filters, the pin of the plunger is firmly and removably supported between the two layers of substrates, so that the light emitting part and It is easy to insert and remove a board, etc. on which a light emitting element is mounted, and it also prevents unstable tilting or unnecessary rotation of the board, etc., and allows for more accurate positioning and direction when inserting the light emitting part and board, etc. Therefore, damage to the fitting portion due to incorrect insertion can be prevented, and the mechanism that achieves these effects is simple, thereby reducing the manufacturing cost of the illuminated switch.
