DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a substrate mounting device for a small light bulb for display, which has an elastomer holder mounted on the playing surface of a pachinko machine to perform a light emitting operation.

[0002]

2. Description of the Related Art Heretofore, an example of a substrate mounting device for a small display bulb of this type that uses a small display bulb having an elastomer holder will be described with reference to FIGS.

In FIG. 6, a hollow portion is formed in the upper surface of a cylindrical elastomer holder 1 and a small light bulb 2 is formed in the hollow portion.
The lower part of the lamp is fitted and fixed to form a small bulb for display 6. The elastomer holder 1 is provided with through holes 17 and 17 penetrating vertically, and the conductive wires 4 and 4 led out from the inside of the light bulb 2 crawl the inner walls of the through holes 17 and 17 and the bottom surface of the elastomer holder 1. Have been led to the side. As shown in FIG. 7, the wiring patterns 19 and 19 are superposed on the upper surface of the printed circuit board 18 at a predetermined interval to form a printed circuit board 1.
8 and the wiring patterns 19, 19 have connection pins 20, 2,
An insertion hole for inserting 0 is formed. The lower portions of the connection pins 20 and 20 are fitted into the fitting holes to stand upright, and the connection pins 20 and 20 are fixed to the printed circuit board 18 via the wiring patterns 19 and 19 by soldering 21 and 21. The conductive wire 22 is configured to be electrically connected to the wiring patterns 19, 19.

Then, the connecting pin 2 is inserted into the insertion holes 17 and 17.
When 0 and 20 are inserted, the wiring pattern 1 is drawn from the conductor 22.
The electric current flows through the connecting pins 20 and 20 and the conductors 4 and 4 via 9 and 19, and the light bulb 2 emits light.

[0005]

However, in the above-mentioned conventional board mounting device for a small light bulb for display, a connecting pin is connected to the printed board as a pre-process for electrically connecting the light bulb having the elastomer holder to the printed board. After the insertion, it had to be soldered, which required a lot of labor and had a problem of poor workability.

In order to eliminate the above-mentioned drawbacks of the prior art, the present invention uses a small display bulb supported by an elastic elastomer holder and a holding plate having locking claws on one side. By sandwiching a single-sided printed circuit board with a wiring pattern, and by electrically connecting the lead wire led from the light bulb to the printed circuit board, soldering work is not required and the small light bulb for display is mounted on the printed circuit board. The purpose is to improve the sex.

[0007]

In order to achieve the above object, a substrate mounting device for a small light bulb for display according to the present invention has a light bulb attached to an upper portion of an elastomer holder and an insert body connected to a bottom portion thereof. A small light bulb for display in which the lead wire led out from the bottom surface of the insert is led to the outside, and an upper surface of a base portion made of an insulating member having elasticity and hardness, which rises from the upper surface-a pair of front and rear rising pieces. And a holding plate provided with outward locking claws extending outwardly at the upper end of the rising piece, an insertion hole for inserting the insertion body and an insertion hole for inserting the rising piece. And a printed circuit board having a wiring pattern on one side thereof, and the printed circuit board and the conductive wire are electrically connected to each other by the clamping action of the clamping plate and the printed circuit board.

[0008]

According to the present invention, the insert body is inserted into the insertion hole of the printed circuit board together with the conductive wire, and the conductive wire protruding downward from the bottom surface of the printed circuit board is bent outward so as to crawl the bottom surface of the printed circuit board. The rising pieces of the sandwiching plate are inserted into the corresponding insertion holes from below the printed circuit board, and the upper surface of the printed circuit board is used as an engagement receiving portion so that the locking claws are locked.

Since the conductor wire is in contact with the bottom surface of the printed board by the sandwiching action of the sandwiching plate, the wiring pattern and the conductor wire are electrically connected to each other so that the light bulb emits light.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described below with reference to the drawings.

1 to 5, a fitting groove for fitting a light bulb 2 is formed in an upper part of an elastomer holder 1 formed in a substantially cylindrical shape, and a rectangular parallelepiped-shaped insert body 3 is continuously provided in a lower part thereof. doing. The electric wire 4 fitted into the fitting groove and led out from the inside of the electric bulb 2 to the outside has two through holes 5 vertically penetrating the holder 1 and the insert body 3,
The display small bulb 6 is formed by crawling 5 and exposing it from the lower surface of the insert body 3 to the outside.

The holding plate 7 is preferably made of a synthetic resin having a high hardness, and the pair of rising pieces 8 and 9 rising from the upper surface of the base portion of the holding plate 7 respectively extend outward at the upper ends thereof. The outward locking claws 10 and 11 are arranged in series. The height of the rising pieces 8 and 9 to the lower surface of the outward locking claws 10 and 11 is preferably equal to the thickness of the printed circuit board 12 described later.

The printed circuit board 12 has a wiring pattern formed only on the lower surface thereof, and has an insertion hole 13 for inserting the insert body 3.
Further, insertion holes 14 and 15 for inserting the rising pieces 8 and 9 are provided at positions symmetrical with respect to the insertion hole 13 in the front-rear direction.

In this embodiment, as shown in FIGS. 3 and 4, the insert 3 is fitted in the insertion hole 13 and the conductors 4, 4 are inserted.
On the lower surface of the printed circuit board 12 and bent outward in the left and right direction, the rising pieces 8 and 9 of the holding plate 7 are inserted from below the insertion holes 14 and 15, and the upper surface of the printed circuit board 12 serves as an engagement receiving portion. The locking claws 10 and 11 are locked to the printed circuit board 12, and the lower surfaces of the printed circuit board 12 and the upper surface of the holding plate 7 hold and hold the conductor wires 4 and 4. The conductive wires 4 and 4 are in close contact with the wiring pattern formed on the lower surface of the printed circuit board 12 to electrically connect to the wiring pattern, and
An electric current is applied to the filament 16 of the light source 2 to cause the light bulb 2 to emit light.

[0015]

According to the present invention, since the conductor wire is sandwiched between the one-sided printed circuit board and the sandwiching plate by the assembly by fitting, the wiring pattern of the printed circuit board and the conductor wire are electrically connected. There is an effect that the soldering work is unnecessary and the mounting work efficiency can be improved.

Further, by supporting the light bulb with a resilient elastomer holder, there is an effect of alleviating the impact on the light bulb.
