Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a display device that is installed in a vehicle instrument and displays information, warnings, etc.

(Prior Art) When a small light emitting diode made of a semiconductor is used as a display device, it is complicated to incorporate it into an instrument. For this reason, as previously shown in Japanese Utility Model Application No. 59-186885, the light emitting body is attached to a holder made of a flexible material, and a cylindrical body formed integrally with the case housing and a cylindrical body disposed on the front side of the housing are used. It has been proposed that the holder be held between a display board and a lead wire of the light emitting body drawn out from a guide groove provided on the side surface of the cylindrical body.

(Problem that the invention attempts to solve) In the mounting structure described above, the lead wire of the light emitting body is
The illuminant tends to tilt when moved inside or outside the cylindrical body. For this reason, when the luminous body is assembled into a meter, the luminous body may tilt when the lead wire is routed for connection, or the luminous body may tilt if the lead wire of the luminous body is touched while assembling other parts. , Care must be taken when assembling instruments including display devices, which hinders the improvement of work efficiency. Also, even after it is incorporated into a meter and installed in a vehicle, etc.
If the lead wire is shaken due to external effects such as driving on rough terrain or engine vibration, the light emitting body may tilt and the normal display function may be lost.

(Means for solving the problem) This project focuses on the fact that the main cause of the inclination of the light emitter is the fluctuation of the lead wire, and has guide parts protruding from both edges of the guide groove in the conventional structure. . In other words, in a display device, a flexible holder with a light emitter attached thereto is held between a cylindrical body formed integrally with the case housing and a display plate disposed on the front side of the housing, and the light emitter is exposed to the display plate. A guide groove is formed from the upper end of the side surface of the cylindrical body, and guide portions having opposing wall surfaces having a predetermined distance are protruded from appropriate locations on both edges of the guide groove, and the lead wire of the light emitting body is connected to the guide portion. It is held or held between the two.

Therefore, when the lead wire is held or held by the guide portion, even if the external lead wire oscillates to some extent, the oscillation is less likely to be transmitted to the light emitter portion, and the inclination of the light emitter can be reduced.

(Example) An embodiment of the present invention will now be described based on the drawings.

Fig. 1 is a perspective view of each part showing the most general embodiment, Fig. 2 shows a state where it is incorporated into a meter, and Fig. 3 shows an enlarged cross section of the main part. Also the fourth
The figure is an enlarged cross section of another embodiment, and FIGS. 5 to 7 show various embodiments of the cylindrical body.

To explain the embodiment shown in FIGS. 1 to 3, a cylindrical body 2 is integrally formed with a case housing 1, and a guide groove 3 and both side edges of the guide groove 3 are formed from the upper end of the side surface of the cylindrical body 2. A guide portion 4 is formed as a protruding opposing wall surface having a predetermined distance. The light emitting body 5 is attached to a holder 6 made of rubber or other flexible material, and a lead wire 7 is extended from the holder 6. A display plate 8 disposed on the front side of the case housing 1 is provided with a through hole 9 through which the light emitting body 5 is exposed. Then, the holder 6 is fitted onto the upper part of the cylindrical body 2, and the display plate 8 is placed on the holder 6 so that the light emitter 5 protrudes from the through hole 9, and the lead wire 7 of the light emitter 5 is guided. The holder 6 is pulled out of the cylindrical body 2 from the groove 3, but is clamped or held by the guide part 4 when pulled out.The holder 6 is fixed when the instrument case is integrated with screws etc. It is held between the stepped portion 10 of the body 2 and the display board 8.

Therefore, when the holder 6 is fitted into the cylindrical body 2, the lead wire 7 is clamped or held by the guide part 4, so even if the lead wire 7 is touched during instrument assembly work, the lead wire 7 will not move. Since the light is not easily transmitted to the holder 6, the light emitting body is prevented from tilting.

Furthermore, as shown in FIG. 4, the shape of the holder 6 and the clamping structure of the holder 6 are not limited to those shown in FIG. As shown in FIG. 7, the guide groove 3 may be provided not only in one place but also in two places, and even if the guide portion 4 does not extend over the entire height of the cylindrical body 2, it may be provided at a necessary location, that is, at the lead-out portion of the lead wire 10. Furthermore, the cylindrical body 2 may also be rectangular, and is not limited to a circular shape. Furthermore, the present invention can be applied to the light emitting body even if it is not a light emitting diode, as long as it is used in the same way.

(Effects of the invention) As described above, in this invention, the light emitting body is mounted on the holder, and the holder is sandwiched between the cylindrical body and the display plate. This is a lead wire with a protruding part, and the lead wire is pinched or held by the guide part and pulled out of the cylindrical body, so it is used to connect external lead wires and to connect the lead wire during assembly work of instruments that have a display device. Since fluctuation of the lead wire due to contact with the wire is difficult to be transmitted to the light emitting body portion (light emitting body, holder), tilting of the light emitting body portion due to the above-mentioned work is prevented, and work efficiency is improved. Further, depending on the structure of the guide portion, it is also possible to have the function of reinforcing ribs of the cylindrical body.
