Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fixture for an LED to a printed circuit board, and more particularly to a fixture for an LED when the LED and the switch are attached to the printed board at positions close to each other.

[0002]

[Prior Art]

 2. Description of the Related Art Conventionally, in some display devices used for various control devices, an LED is provided inside, and when the knob portion of the switch is pushed, the knob portion of the switch is turned on.

For example, in the case of the display device in the automobile air conditioner shown in FIGS. 3 and 4, when the knob 7 attached to the display panel 10 provided on the front surface of the housing 1 is pressed, the knob 7 is displayed. The attached noble retainer 6 is pushed rearward, and the switch pushing portion 6a of the noble retainer 6 pushes the operating element 52 of the switch 5 attached to the printed circuit board 2 to set desired functions such as cooling and heating. At the same time, the LED 3 mounted above the switch on the printed circuit board 2 is turned on, and the LED 3 is emitted to the outside through the indicator lens 8 as a lens to indicate that the ON operation is being performed.

Further, a light source 9 is provided on the printed circuit board so that the indications such as “ON” and “OFF” of the knob 7 are emitted so that the desired position of the switch knob can be easily visually recognized even at night. The colors of the LED 3 and the light source 9 are changed to make it easier to see.

Here, when the light source 9 emits light, it is difficult to determine whether or not the indicator portion is illuminated even if the LED 3 is illuminated due to the light from the light source 9, so that conventionally, the outer periphery of the LED 3 is surrounded by a wall. It is surrounded by the LED holder 4 including the parts 4a and 4b so that the light emission of the indicator part can be easily seen.

Further, the LED holder 4 usually has a plurality of holding holes for supporting the LEDs.

[0007]

[Problems to be solved by the device]

 However, according to the conventional configuration, in particular, the entire outer circumference of the LED 3 is surrounded by the LED holder 4 and the switch main body 51 is provided under the LED holder 4, so that the upper surface 51 of the switch main body 5 is provided as shown in FIG. Since there is an A dimension from the top to the upper surface of the bottom wall of the LED holder 4, there is a problem that the B dimension shown in FIG. 4A cannot be reduced. In the case of automobile air conditioners, it is desirable to make the height of the display device as small as possible in order to effectively use the space.

[0008] Although the LED holder 4 has a holding hole for supporting the LED, the LED holder is often formed in a symmetrical shape at the top and bottom, and at a glance the mounting position can be determined. Hard to do. For example, in the display device shown in FIG. 3, five knobs are arranged on the right side, but as shown in FIG. 3, there is no indicator in the “OFF” part, and therefore an LED is also arranged inside. Therefore, no holding hole is provided in the “OF F” portion of the LED holder. Therefore, when the mounting position of the LED holder is turned upside down, there is a problem that the LED is crushed because the LED is inserted into a portion where the holding hole is not provided. This is a problem not only in the LED holder as described above but also in the LED holder in which the holding holes are not provided for the left and right objects.

Therefore, the present invention can provide a LED holder that can reduce the total height of a display device having an LED and a switch for lighting the LED, and further can accurately determine the mounting position of the LED. It is intended.

[0010]

[Means for Solving the Problems]

 According to the present invention, in an LED holder that supports an LED mounted on a printed circuit board in a position close to a switch, a holding hole for holding the LED therein is formed, and an opening is formed on a lower surface of the switch. A switch formed with an LED housing portion configured as a housing body having a portion and an insertion portion that is connected to the lower portion of the LED housing portion and is in contact with the switch main body of the switch and through which an operator of the switch can be inserted. A pressing portion, and one surface of the switch is engaged with an opening portion of the LED storage portion when the LED holder is fixed, and the one surface of the switch forms a part of a wall portion that covers the LED. It is characterized by having done.

[0011]

[Action]

 Since the LED holder according to the present invention has a holding hole capable of holding the LED inside, the LED is inserted into the holding hole, and the operator of the switch is inserted through the insertion hole of the switch holding portion. When the LED holder is fixed to the switch body by bringing the part into contact with the switch body, the upper surface of the switch body forms a part of the wall that covers the LED, so that the distance between the LED and the switch can be shortened, and the entire display is shown. The height of the device can be suppressed. Moreover, since the upper surface of the switch body forms a part of the wall portion that covers the LED, the illumination of the LED is not affected by other light sources in the display device.

Further, since the LED holder according to the present invention is configured as described above, the mounting positional relationship is clear, and the LED holder is not erroneously assembled.
