BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a controller for electrical equipment, and more particularly to a controller for electrical equipment that displays operating status using light emitting elements.

0002

2. Description of the Related Art In recent years, as electronic control has become more and more microcomputerized, it has become mainstream to display the operating status of electrical equipment controllers (hereinafter referred to as controllers) using light emitting elements. Additionally, as users get older, there is a growing demand for controllers that display the operating status in an easy-to-understand manner. In a conventional controller of this type, a light emitting element 21 and a support holder 22 are arranged on a print base 20 as shown in FIG. 5, and the light emitting element 21 is soldered with solder 23 by dipping from the opposite side of the print base 20. The support holder 22 can be attached to the print base 20 by press-fitting the legs 25 provided in the support holder 22 into holes (not shown) provided in the print base 20.
Fixed. Further, the support holder 22 is formed with a cylindrical wall 26 that is approximately equal to the outer circumference of the light emitting element 21 so as to cover the entire circumference of the light emitting element 21, and
A seat portion 27 is provided for receiving the bottom portion of the container. Furthermore, the light emitting element 21 is located in a relative position to a rib 30 provided inside the periphery of the opening 29 of the controller case 28, so that the entire circumference is covered by the rib 30. Further, numeral 31 denotes a film-like display board, which is attached to the outer surface of the controller case 28 so as to cover the opening 29.

0003

However, in such a conventional configuration, the cylindrical wall 26, which is approximately equal to the outer circumference of the light emitting element 21, is formed to cover the entire circumference of the light emitting element 21. If the size of the opening 29 of the case 28 is made larger than the outer circumference of the light emitting element 21, a problem will occur because the support holder 22 or print base 20 will be visible from the outside. In other words, the controller case 28
The size of the opening 29 is smaller than the outer circumference of the light emitting element 21, making it difficult for the user to see the operating state. In addition, due to variations in the mounting of the light emitting element 21 and the print base 20 during assembly, the light emitting element 21 and the opening 29
The position of the image may be shifted, resulting in an unsightly appearance. Furthermore, the light emitting element 21 is connected to the opening 29 of the controller case 28.
Since the light emitting element 21 is covered with a rib 30 provided on the peripheral inner surface of the light emitting element 21, there is a risk that the light emitting element 21 will hit the rib 30 during assembly and stress will be applied to the soldered portion of the light emitting element 21. After the bottom surface of the light emitting element 21 is brought into contact with the seat 27 provided on the support holder 22, the legs of the light emitting element 21 are bent and soldered with the solder 23 by dipping from the opposite side of the print base 20. Therefore, there is a possibility that the light emitting element 21 may be lifted up, resulting in a problem that the mounting becomes unstable.

SUMMARY OF THE INVENTION The present invention has been made to solve these conventional problems, and it is an object of the present invention to provide a controller whose operating status is easy for the user to see and which is easy to assemble.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the controller of the present invention includes a controller case consisting of an upper case and a lower case, a print base provided inside the controller case, and a controller disposed on the print base. The device includes a plurality of light emitting elements and a support holder that integrally supports the plurality of light emitting elements, and the support holder covers the periphery of the light emitting elements and has a tip side wider than a base side of the light emitting element. A conical or elliptical conical wall is provided, and a claw for holding the lower part of the light emitting element and a seat part for receiving the bottom part of the light emitting element are provided, and the plurality of light emitting elements and the support are provided. The holder is arranged close to the inner wall of the upper case, and the plurality of openings provided in the upper case correspond to the positions of the plurality of light emitting elements.

[0006]

[Operation] With the above configuration, the controller of the present invention has a support holder that covers each of a plurality of light emitting elements, and has a conical shape or a conical shape in which the tip side of the light emitting element is wider than the base side.
By providing an elliptical conical wall, the size of the opening provided in the controller case can be made larger than the outer circumference of the light emitting element, and the direction of the light from the light emitting element can be concentrated towards the opening side. This makes it easier for the user to see the operating status. Further, even if the light emitting element and the opening are misaligned due to variations in the attachment of the light emitting element and the print base during assembly, the light emitting element and the opening appear uniformly wide, resulting in a good appearance. Furthermore, the multiple light emitting elements and the support holder are placed close to the inner wall of the upper case, and the multiple openings provided in the upper case are opposed to the multiple light emitting elements, making it easier to assemble. No stress is applied to the soldered portion of the light emitting element. Furthermore, since the support holder is equipped with a claw that holds the lower part of the light emitting element, it prevents the light emitting element from lifting up, and there is no need to bend the legs of the light emitting element when soldering by dipping. It will be good.

[0007]

As shown in FIG. Inside the controller case 1, a printed base 4 on which electrical wiring components and the like are mounted is arranged, and is electrically connected to a cord 5 for supplying power. Reference numeral 6 denotes a support holder, which integrally supports a plurality of light emitting elements 8 soldered in a straight line with solder 7 on the print base 4, and inserts legs into holes (not shown) provided in the print base 4. The portion 10 is press-fitted and attached to the print base 4. The support holder 6 and the plurality of light emitting elements 8 are located close to the inner wall of the upper case 2, and the plurality of openings 11 provided in the upper case 2 and the plurality of light emitting elements 8 are positioned relative to each other. There is.

Windows 12 and 13 are provided in the opening 11 of the upper case 2, and are welded and fixed by ultrasonic welding or the like so as to cover the opening 11 from the inside of the upper case 2. Reference numeral 14 denotes switches with knobs 14' attached thereto, which are disposed on the print base 4, and when turned on, supply a low current to the light emitting element 8 to light the light emitting element 8.

More specifically, the mounting state of the support holder 6 and the light emitting element 8 will be explained based on FIG. 4. The support holder 6 that integrally supports a plurality of light emitting elements 8 has a conical or elliptical conical shape that covers the periphery of each of the plurality of light emitting elements 8 and is wider at the tip side than the base side of the light emitting element 8. A wall 15 is provided. In addition, the support holder 6 includes
A seat part 16 for receiving the bottom surface of the light emitting element 8 and a claw 17 for holding the lower part of the light emitting element 8 are provided.

In the above structure, the support holder 6 is provided with a conical or elliptical conical wall 15 that covers the periphery of each of the plurality of light emitting elements 8 and is wider on the tip side than on the root side of the light emitting element 8. Therefore, the size of the opening 11 provided in the upper case 2 can be made larger than the outer circumference of the light emitting element 8, and the light emitted from the light emitting element 8 can be concentrated towards the opening 11 or the windows 12 and 13. This makes it easier for the user to see the operating status. Further, even if the light emitting element 8 and the opening 11 are misaligned due to variations in the mounting of the light emitting element 8 and the print base 4 during assembly, the light emitting element 8 and the opening 11 can be seen uniformly over a wide range, resulting in a good appearance. Furthermore, the plurality of light emitting elements 8 and the support holder 6 are brought close to the inner wall of the upper case 2, and the positions of the plurality of light emitting elements 8 are made to correspond to the plurality of openings 11 provided in the upper case 2. Therefore, stress is not applied to the soldered portion of the light emitting element 8 by the solder 7 during assembly. Furthermore, since the support holder 6 is provided with a seat 16 for receiving the lower part of the light emitting element 8 and a claw 17 for holding the lower part of the light emitting element 8, the height of the light emitting element 8 can be regulated and the height of the light emitting element 8 can be regulated. There is an effect that it is possible to prevent the light emitting element 8 from lifting up, and it is not necessary to bend the legs of the light emitting element 8 when soldering with the solder 7 by dipping, resulting in good assembly efficiency.

[0011] In this embodiment, the controller has been described, but similar effects can be obtained in the main body which displays the operating state using a light emitting element.

0012

As is clear from the description of the embodiments above, according to the controller of the present invention, the supporting holder is provided with a conical shape that covers the periphery of each light emitting element and is wider on the tip side than the base side of the light emitting element. By providing a wall shaped like a cone or an elliptical cone, the size of the opening provided in the controller case can be made larger than the outer circumference of the light emitting element, and the direction of the light emitted from the light emitting element can be directed toward the opening. Since it can be consolidated, the operating status can be easily seen by the user.

Furthermore, even if the light emitting element and the opening are misaligned due to variations in the mounting of the light emitting element and the print base during assembly, the display looks uniformly wide, resulting in a good appearance.

Furthermore, since the plurality of light emitting elements and the support holder are placed close to the inner wall of the upper case, and the plurality of openings provided in the upper case are opposed to the positions of the plurality of light emitting elements, assembly is facilitated. At times, no stress is applied to the soldered portion of the light emitting element.

Furthermore, since the support holder is provided with a seat portion that receives the lower surface of the light emitting element and a claw that holds the lower part of the light emitting element, the height of the light emitting element is regulated and the light emitting element is prevented from floating up. However, when soldering by dipping, there is no need to bend the legs of the light emitting element, resulting in good assembly.
