Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an illuminated display structure for indicating the rotational position of a rotary operator of an electrical component such as a rotary switch or rotary volume.

In this type of electrical component, it is common to have an indication line engraved on the rotary operation knob, and to read the rotational position of the operation knob from the position of this indication line.

However, if this electrical component is used indoors with little light, υ
Another problem is that the instruction line may be difficult to see when attempting to confirm the rotational position of the operating knob from a distance.

SUMMARY OF THE INVENTION Accordingly, the present invention provides an illuminative display of the rotational position of a rotary operator of an electrical component in place of the conventional indication using an indicator line.
Alternatively, to provide an illumination display structure for a rotary control element in an electrical component that can reliably read the rotational position of the rotary control element quickly even when the rotational position of the rotary control element is read from a remote position. The purpose is to

Based on this object, the present invention provides an electric component including a rotary operator whose one end side is rotatably held in a main body, in which a conductor "I" that passes through the center of one end surface and the outer surface of the other end of the rotary operator is provided. '(-, an illumination display for a rotary controller attached to an electrical component configured such that a passage is provided in the rotary controller and a light emitting body is fixed to the main body with a light emitting body facing the end of the light guiding passage on the main body side. It is characterized by its structure.

Next, this invention will be explained based on FIG.

FIG. 1 shows a case where the present invention is applied to a rotary switch. In FIG. 1, 1 is the main body of a rotary switch. This main body 1 has a cylindrical body 2 and a housing 3 for housing contacts fixed to one end of this cylindrical body 2. Moreover, this housing 3 is composed of two housing members 33.3a'. Contact mounting plates 4, 4' are fixed to opposing walls 3b, 3b' of the housing members 3a, 3a'.

5 is a rotary operator. This rotary operator 5 has a rotating shaft 6
and an operating knob 7 fixed to this rotating shaft 6. By inserting one end of this rotary shaft 6 into the housing 3 and rotatably holding the intermediate portion of the rotary shaft 6 within the cylindrical body 2, one end of the rotary operator 5 is attached to the main body 1. It is rotatably held. A contact mounting member 8 is fixed to the outer peripheral surface of one end of the rotating shaft 6, and movable contacts 9, 9' are mounted to the contact mounting member 8. The movable contacts 9, 9' are attached to the contact mounting plate 4,
It is designed to be intermittently brought into contact with a fixed contact (not shown) fixed to the surface of 4'.

A hole 10 is formed in the above-mentioned rotating shaft 6 at the center of both end faces thereof, and a hole 11 communicating with the hole 10 is formed in the operating knob 7. This hole 11 opens at the peripheral edge of the end face of the operating knob 7. An optical fiber 12 as a light guide is fitted into both holes 10° 11, one end 12a of this optical fiber 12 protrudes from one end of the rotating shaft 6, and the other end 12b of the optical fiber 12 is connected to the operating knob 7. It slightly protrudes from the end surface in a substantially spherical shape. In this way, a light guide path is formed in the rotary operator 5 by the optical fiber 12.

Moreover, the light guide passage passes through the center of one end surface of the rotary operating element 5 and the outer surface of the other end, as shown in the figure.

13 is a housing for storing a light emitter. This housing 13 is composed of a fixed casing member 14 fixed to the casing member 3b, and a completely rounded casing member 15 attached to the fixed casing member 14. A hole 16 is bored in the fixed housing member 14, and one end 12a of the optical fiber 12 is rotatably fitted into the end of the hole 16 on the rotating shaft 6 side. A light emitting diode 17 as a light emitter is fitted.

Next, the function of the illumination display structure of the rotary operator in the electrical component having such a configuration will be explained.

First, when an electrical product using a rotary switch is turned on, the light emitting diode 17 is energized,
Wiring is done in advance so that the light emitting diode 17 emits light.

Next, when this electrical product is turned on, the light emitting diode 1
7 emits light, and the light from this light emitting diode 17 is guided to the peripheral edge of the end face of the operating knob 7 via the optical fiber 12. Then, light is emitted from the end 12b of the optical fiber 12 to the outside, and the rotational position of the operating knob 7 is displayed by illumination. Also, by rotating the operation knob 7,
While the movable contacts 9, 9' are rotated together with the rotating shaft 6 to switch contact from one of a plurality of fixed contacts (not shown) to another, the end 12b of the optical fiber 12 is also rotated in the same direction. Then, an instruction is given to change the rotary operator's 50 rotation position ICC.

In the embodiment described above, an example was shown in which the optical fiber 12 was extended into the hole 11 of the operating knob 7, but the invention is not necessarily limited to this. For example, as shown in FIG.
A colored translucent illumination body 18 is fitted inside, and one end surface 18a of this illumination body 18 is connected to the end surface 1 of the optical fiber 12.
2c, and the other end 18b of the illuminator 18 is slightly protruded from the peripheral edge of the end face of the operating knob 7, so that the optical fiber 12 and the illuminator 18 form a light guide path. Good too. In the case of this embodiment, since the illuminator 18 is provided separately from the optical fiber 12,
By replacing the illuminant 18 with one of a different color or shape, the illumination display format can be easily changed.

As described above, the present invention provides a light guiding passage passing through the center of one end surface and the outer surface of the other end of the rotary operator in the rotary operator, and also provides a light emitting body at the end of the light guiding passage on the main body side. T of the configuration defined on the main body by biting! T. Since the electrical component has an illuminated display structure for the rotary controller, even if this electrical component is used indoors with low light intensity, or when reading the rotational position of the rotary controller from a remote location, the rotating This has the effect of being able to reliably read the rotational position of the operator.
