Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a light-emitting lever protruding from a control panel in a ventilation system installed in an automobile.

This type of light-emitting lever that is conventionally used is
A glass fiber is used as a light guide to the front side. That is, an indicator light bulb is installed inside the ventilation, a glass fiber is arranged between the light bulb and the knob, and the glass fiber is fixed to the lever so that it can be moved together with the lever. be. However, glass fiber not only does not provide a sufficient amount of light to the front surface of the lever, but also has the disadvantage that the glass fiber itself is expensive, leading to an increase in the overall cost.

The present invention was developed in view of these circumstances, and its purpose is to provide an inexpensive light-emitting lever that can provide a sufficient amount of light.

The present invention was developed to achieve this purpose.
A printed circuit board or flexible printed board is fixed to the switch lever, a light source connected to the current is attached to the tip of the switch lever, a heat shrink tube is covered over the entire switch lever, and an elastic material is attached to the tip of the switch lever. The light-emitting lever is characterized in that the light source is exposed at the center of the front side of the knob, and the light source is provided at the tip of the lever, and since this light source is exposed, the illuminance is low. It provides a sufficient amount of light, consumes little power, is inexpensive by attaching a printed circuit board or flexible printed board, and eliminates the need for replacement by using a light emitting diode as the light source, allowing stable and long-term use. It is.

Next, the present invention will be explained in more detail with reference to the illustrated embodiments. Reference numeral 1 denotes a switch lever having a plate shape, and a printed circuit board or flexible printed board 3 is adhesively fixed to the upper surface of the lever via, for example, double-sided adhesive tape 2. do. A conductive pattern 4 is printed on this printed circuit board or flexible printed board, and a light source 5 of an appropriate shape, such as a light emitting diode, is soldered to one end (tip) of the conductive pattern 4 for electrical connection. A lead wire 6 is also connected to the other end (rear end) by soldering.

After these fixings and connections are completed, a heat shrink tube 7 is applied and shrunk to wrap around the switch lever 1 and the printed circuit board 3 to insulate it from the outside, and a knob 8 is detachably attached to the tip of the switch lever 1. . The knob 8 is made of a single material such as rubber, and has a space 9 for the light source to enter therein, and the front side of the space is an opening 10. The light source 5 is exposed in the opening 10 and is separated from the light source. The structure is such that the light can be directly projected to the outside. Note that the reference numeral 11 in the figure is a ventilation panel.

The light-emitting lever of the present invention having the above structure penetrates the gap 11a of the ventilation panel 11 so that its tip protrudes to the outside, and by inserting the knob 8 into the protruding end, the light source 5 can be attached to both sides of the light source 5. The intensity of the operation can be adjusted from the switch by pinching and operating the knob, and it is mounted so that it can be operated like a normal switch lever, and when operated, the light source 5 is turned on at the same time as the switch.
lights up to indicate that it is in operation.

As explained above, the light-emitting lever according to the present invention allows the switch lever to be electrically wired by using a printed circuit board or a flexible printed board, and can be formed without increasing the thickness of the switch lever, and has a light source at its tip. Since it is attached and exposed as it is, a sufficient amount of light can be obtained, significantly reducing power consumption and making it easy to see the operating status. In addition, by attaching a heat shrink tube, insulation from the outside can be easily achieved, and the configuration of the lever itself and wiring is simplified.The lever and knob are formed separately and can be attached and detached, making it easier to perform maintenance. This is extremely advantageous, and since it does not use glass fibers, it can be provided at low cost.
