Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a light emitting body mounting fixture for a switch display of a television, a video tape recorder, etc., which is equipped with a switch for blinking a light emitting body such as a light emitting diode.

For example, in the channel display section of a television, structures shown in FIGS. 4 and 5 have conventionally been used. As shown in FIG. 5, the front panel 5 has a push button hole 50 and a light emitter window 51 corresponding to the light emitter 3 position.

In FIG. 4, a light emitter 3 is fixed to the printed circuit board 1 by soldering via a light emitter mount 2, and is electrically connected to the light emitter 3 to blink the light emitter 3. A push button switch 4 is provided.

Contact piece 42 of switch 40 of push button switch 4
Fit the push button 41 to the front panel 5.
The pushbutton hole 50 is made to protrude from the pushbutton hole 50 .

Therefore, in the process of assembling the pushbutton switch 4, especially when it comes to fitting the pushbutton 41 into the switch 40, the current situation is that it requires a large amount of man-hours because the pushbutton 41 itself is small. It has become a process.

Furthermore, if one or both of the push button hole 50 and the light emitter window 51 provided in the front panel 5 are not made larger than necessary, the front panel 5 cannot be attached to the light emitter mount. 2 and the pushbutton switch 4, there was a problem in that it did not fit properly due to subtle dimensional errors.

The present invention focuses on the above problem, and the surface plate of the light emitter mount is equipped with a light emitter holder that holds the light emitter, and the light emitter holder is provided at a position corresponding to the contact piece of the push button switch provided on the printed circuit board. By protruding outward protrusions, forming elongated holes surrounding the protrusions in the surface plate, and forming bullet pieces containing the protrusions, the protrusions can play the role of conventional push buttons 41. This is what I did. That is, the conventional light emitter mount 2 and the pushbutton 41 are integrally molded using members such as plastic, thereby reducing the number of parts and the number of man-hours required for attaching the pushbutton.

Next, the present invention will be specifically explained based on embodiments shown in the drawings.

FIG. 1 illustrates a light emitter mount according to the present invention,
A sectional view taken along the line of FIG. 1 is shown in FIG. In FIGS. 1 and 2, the switch board 1
is a plurality of light emitting diodes 30 and a plurality of switches 4
The circuit is configured so that 0 can be installed in parallel.

The light emitter mount 2 includes a surface plate 25 that covers the light emitting diode 30 and the switch 40, and
The surface plate 25 has a light emitting body receiving part 20 protruding inward corresponding to the mounting position of the light emitting diode 30, and the receiving part 20 has a recessed hole 21 for receiving the light emitting diode 30, and a light emitting diode is provided at the bottom of the hole. A through hole 22 is provided to communicate the printed circuit board 1 with the printed circuit board 30.

Furthermore, the surface plate 25 of the light emitter mount 2 has a protrusion 24 projecting outward at a position corresponding to the contact piece 42 of the switch 40, and a U-shaped elongated hole 26 surrounding the protrusion 24. A bullet piece 23 including a protrusion 24 is formed. In this embodiment, an auxiliary elongated hole 27 is further formed between the parallel elongated holes 26 with one end aligned with the end of the elongated hole 26, and the thickness of the bullet piece 23 is reduced.

Here, the bullet piece 23 is capable of being displaced within an elastic range corresponding to the stroke distance of the switch 40.

In addition, the shape of the elongated hole 26, the presence or absence of the auxiliary elongated hole 27,
The thickness etc. of the bullet piece 23 are appropriately determined depending on the material of the light emitter mount 2 used, the mounting position of the switch 40, the structure of the switch 40, etc., and it goes without saying that various changes are possible. It is.

A locking rod 6, a retainer 7, and a fixing piece 8 are continuously provided inwardly protruding from the surface plate 25 of the light emitter mount 2. A claw 60 projects from one end of the locking rod 6, and the locking rod 6 is locked to the printed circuit board 1 via a retainer 7, and the fixing piece 8 is fixed to the printed circuit board 1 with screws.

Note that the light emitting body is not limited to the light emitting diode 31, but a small lamp or other light emitting body may be used, and various changes can be made by forming a light receiving part and a conductor hole according to the shape of the light emitting body. Of course it is possible.

The light emitter mount 2 configured as described above is integrally molded using a member such as plastic, and the protrusions 24
can serve as the push button 41 of the push button switch 4 in FIG.

Therefore, when the protrusion 24 formed on the display plate 25 of the light emitter mount 2 is pressed, a signal from the switch 40 is transmitted to the circuit configured on the printed circuit board 1 via the switch contact piece 42, and the corresponding light emitting diode is activated. 3
0 lights up. FIG. 3 shows the state in which the protrusion 24 is pressed. When the protrusion 24 is released, the elasticity of the bullet piece 23 causes the protrusion 24 to return to its original position, but the light emitter continues to be lit due to the electric circuit configuration.

In a display device in which a light emitter mount and a pushbutton of a pushbutton switch are configured separately, the present invention provides an external display on the surface plate of the light emitter mount at a position corresponding to the contact piece of the pushbutton switch. By forming a facing protrusion, opening a long hole surrounding the protrusion, and providing a bullet containing the protrusion, the protrusion on the surface plate can function as a conventional push button. It is. By integrating the light emitter mount and the conventional pushbutton in this way, the number of parts can be reduced, reducing the number of man-hours required to fit the pushbutton to the switch contact piece, and further improving dimension alignment with the front panel. This has excellent effects, such as streamlining the assembly work by being able to do this easily and accurately, and also making it possible to eliminate the front panel by molding the light emitter mount with metallic molding.

It should be noted that the present invention is not limited to the above-mentioned configuration, and it goes without saying that various modifications can be made within the technical scope described in the claims of the utility model registration.
