Description

[Detailed Description of the Invention] The present invention relates to an illuminated switch in which a panel mounting flange is separably fixed to the case body.

Illuminated switches are widely used in the operation panels of electronic devices such as various control devices because of the convenience of integrating the switch function and display function. The upper end is located on the front side of the operation panel, and the lower end is housed inside the device and attached to the panel.

Conventionally, the above-mentioned mounting method involves integrally forming a flange part for panel mounting on the upper end of the case of the illuminated switch, and attaching a mounting bracket to the side of the case and inserting it into the mounting hole drilled in the panel. The illuminated switch was fixed by placing the flange part on the front side of the panel and holding the edge of the mounting hole between the flange part and the mounting bracket. On the other hand, with an illuminated switch built into a device, the terminal led out from the bottom of the case and the internal circuit of the device are wired together by soldering or wire wrapping, but it is difficult to maintain the electronic device. If it becomes necessary to remove the operation panel from the main body of the device, the flange part is integrally formed on the case of the illuminated switch, so the operation panel cannot be removed unless all wiring is disconnected and the illuminated switch is removed from the panel. This was not possible, and the work was complicated.

The present invention was devised in order to eliminate the above-mentioned drawbacks, and the purpose is to provide an illuminated switch that can be removed from the operation panel without removing the wiring, and that allows easy maintenance of electronic equipment. be.

In order to achieve the above objectives, the illuminated switch of the present invention focuses on the use of a barrier for appearance and prevention of operation when the illuminated switch is attached to an operation panel, and has a separate case body. A case is constituted by a flange for panel mounting, and an engagement part for positioning is provided on the upper end face of the case body and the bottom face of the flange, and a flange part is provided at the upper end. A barrier having a groove formed in the lower part to fit with the flange of the case is removably attached to both sides of the case to fix the case body and the flange, and this is implemented as shown in the drawings. This will be explained based on an example.

FIG. 1 shows an illuminated switch according to an embodiment of the present invention, in which 1 is an illuminated switch, 2 is a case, 3 is a case body, 4 is a flange, and 5 is a barrier. The case 2 is composed of a case body 3 and a flange 4, which are each formed separately from synthetic resin, and has a fitting hole 3a formed in the upper end surface of the case body 3.
A protrusion 4a formed on the bottom surface of the flange 4 is inserted into the flange 4 to align them with each other. Incidentally, a switch means and a display means are housed inside the case 2,
A display operation section 6 is arranged in the opening.
The barrier 5 is integrally molded from synthetic resin and has a flange portion 5a at its upper end, and a groove 5b that engages with the flange 4 of the case is formed at the lower part of the flange portion 5a. By attaching protrusions 5c protruding on the inner surface of the barrier to the fitting holes 3b formed in the case body 3 in a removable manner and attaching them to both sides of the case 2, the case body 3 and the flange 4 are removably engaged and fixed, thereby increasing the strength of fixing the case body 3 and the flange 4. 7 is case 2
The mounting bracket is made of a spring material and has a substantially U-shaped cross section at both ends of the base, and has a pair of arms 7a protruding from both ends thereof.

The barrier 5 described above is used when one illuminated switch 1 is attached to the operation panel, but it is also possible to connect a large number of illuminated switches and place a barrier between each switch to attach the operation panel. When the barrier 5 is attached to the barrier 5, the grooves 5b and the protrusions 5c described above may be formed on both sides of the barrier 5 and engaged with the illuminated switches on both sides.

To attach the illuminated switch with the above configuration to a panel, insert the illuminated switch 1 into the mounting hole 8a of the panel 8 from the front of the panel as shown in FIG. comes into contact with the front edge of the mounting hole 8a, and the arm 7a of the mounting bracket presses the side surface of the mounting hole 8a,
The edge of the mounting hole 8a is held between the bottom surface 4b of the flange 4, the bottom surface of the barrier 5, and the mounting bracket arm 7a, and is fixed to the panel. To remove the illuminated switch from the panel, push the arm 7a of the mounting bracket inward to flex it, pull out the entire illuminated switch to the front of the panel 8 as shown in Figure 2b, and then remove it from the panel 8 as shown in Figure 2c.
As shown in the figure, the barrier 5 is removed from the case 2, the case body 3 and the flange 4 are separated, and the case body 3 is pushed behind the panel 8 and removed.

In the figure, 9 is a terminal led out from the lower end of the illuminated switch 1, and 10 is a wiring connecting the internal circuit of the electronic device and the terminal 9 of the illuminated switch.

As explained above, the illuminated switch of the present invention positions the flange and the case body using the engaging parts provided on the bottom surface of the flange and the upper end surface of the case body, and furthermore, the flange is positioned by the barriers removably attached to both sides of the case. Since it is fixed to the upper end surface of the case body, the flange and the case body can be separated as necessary, and the attached electronic device can be easily removed from the operation panel without removing the wires connected to the terminals. Therefore, electronic equipment equipped with the illuminated switch of the present invention can be easily maintained, such as by being able to remove the operation panel from the main body of the equipment without having to perform complicated wiring removal work.
