Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a temporary print holding device that is attached to a meter.

[Prior art] Conventionally, this type of printing temporary printing that holds the pulp of various warnings displayed inside the meter is placed on the bottom or top side of the case that holds the meter, and is printed using screws, etc. However, it takes time to assemble the screws, and the screws tend to spin idle due to over-tightening.

Furthermore, as described in Japanese Utility Model Application Publication No. 48-20450, it has been considered to fix the printed board only with the protruding piece provided on the bottom of the case. In addition to this protrusion, it is necessary to use a mounting foot for an instrument gauge, etc., or to fix it with screws, which increases the number of parts and requires more man-hours for assembly. There is a drawback.

[Purpose of the invention]

In order to solve the above-mentioned drawbacks, the present invention fixes the case and the wind plate and simultaneously fixes the printed board by using the U-shaped protrusion formed on the case and the print temporary holding pawl formed on the wind bleat. By doing so, it is an object of the present invention to enable a printed board to be easily fixed to a case without using screws, with a small number of parts, and without requiring any special work for fixing the printed board.

〔Example〕

The present invention will be described below with reference to embodiments shown in the drawings.

In Figures 1 and 2, a U-shaped opening is formed on the outer surface of the upper part of a case 1 made of synthetic resin that houses an instrument such as a speedometer, from the bottom 1' of the case 1 toward the front of the instrument. The mold protrusion 2 is integrated with the case 1 made of synthetic resin,
One or more are formed at appropriate intervals. Fittings protrude toward the bottom of the case l on both sides near the corners of the synthetic resin wind plate 4, which holds the front acrylic 3, which is a transparent member that protects the inside of the front of the instrument, by welding, gluing, etc. A plurality of pawls 5 are provided, and a flexible portion 5a protruding outward is formed on the outside of the fitting pawl 5. Furthermore, the wind plate 4 is provided with one or more print temporary holding pawls 6 that protrude toward the bottom surface 1' of the case, and a chamfer 6 is formed on the printed board 8 side at the tip of the holding pawl 6. It is a provision. The fitting pawl 5 on the outer surface of the case 1
A pawl fitting hole 7 is formed at a position opposite to.

A printed board 8 that holds various warnings displayed in the instrument and a lighting bulb 9 is disposed on the outer surface of the upper part of the case 1, and is connected to the U-shaped protrusion 2 of the case 1 and the wind plate. With the print temporary holding pawl 6 of 4,
It is fixedly held in case 1.

In the above configuration, one end surface of the printed board 8 is press-fitted into the opening of the U-shaped protrusion 2 provided on the bottom surface 1' side of the case 1, and the wind plate 4 is inserted in the front direction of the case 1. Then, the wind plate 4 and the case 1 are fixed by pushing toward the bottom surface 1' and fitting the fitting pawl 5 into the case fitting hole 7. At the same time, the print temporary holding pawl 6 provided on the wind plate 4 slides on the surface of the printed board 8, and one end surface of the printed board 8 is press-fitted into the opening of the U-shaped protrusion 2. The printed board 8 is fixedly held in the case 1 by pressing the opposite end surface.

In addition, the chamfer 6 provided on the end surface of the print temporary press pawl 6
' is for making it easier to fit the wind plate 4 and the case 1 together.

The same effect can be obtained even if the shape of the U-shaped protrusion 2 (or the print temporary presser 6) is semicircular or tapered as shown in FIG. 3 or 4. can.

〔Effect of the invention〕

As described above, in the present invention, in addition to the U-shaped protrusion formed on the case, there is also a wind play which is a separate part.
- A plate for temporarily holding the print is formed on the plate, and since the printed board is fixed with both, no other parts are required, and the printed board is fixed at the same time as the wind plate and the case are fixed. Therefore, there is an excellent effect that no other special work for fixing the printed board is required.
