Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light bulb mounting device for mounting and connecting a light bulb to a circuit board.

[0002]

2. Description of the Related Art In game machines such as game machines and pachinko machines, a large number of light bulbs are provided on the surface of a board or a decorative panel in order to enhance a game effect or to give instructions on a game method. It is made to go out through the decorative panel. As a light bulb, a so-called silicon light bulb that is easily attached and detached is often used.

In this silicon bulb, a portion corresponding to a base is formed of silicone rubber, and a pair of pins on a circuit board are inserted into the silicone rubber portion, so that wiring and attachment to the circuit board are performed. .

[0004]

The pins on the circuit board are:
It is inserted into a pin insertion hole formed in the circuit board, and in that state, is soldered in advance to a conductive pattern on the circuit board. For pin setting work, insert the pins one by one with fingers or tweezers into the pin insertion holes and solder them. Although this work is devised using jigs and the like by each company and each person, it is a difficult work.

[0005] In some cases, the pins and the like are not properly processed and do not turn on even when the bulb is assembled. This device, which eliminates the need for pins and soldering, offers a significant increase in work efficiency.

[0006]

According to the present invention, there is provided a light bulb mounting apparatus comprising: a light bulb incorporated in a socket body; an insertion hole formed in a substrate; and a connecting member attached to a lower portion of the socket which can be inserted into the insertion hole. It is composed of a substrate fixing collar and an extension assisting member. A thin skirt is attached to the edge of the outer periphery of the lower part of the socket, and a projection for preventing rotation is attached to the flat surface.

[0007]

When the light bulb mounting device of the present invention is extended from the insertion hole on the substrate through the auxiliary member, and pulled from below, the connecting member and the substrate fixing collar are elastically deformed to go under the insertion hole and release the extension auxiliary member. The connecting portion shrinks so that the board is sandwiched between the lower part of the socket and the collar. The conductive pattern on the upper part of the board and the conductor coming out of the lower part of the socket come into contact with each other. The extension assisting member is cut after assembly.

[0008]

[1] A first embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a circuit board. An insertion hole 2 matching the shape of the base fixing collar is formed at an arbitrary position of the circuit board 1. This insertion hole is slightly smaller than the substrate fixing collar.

On the circuit board 1, a pair of conductive patterns 3a and 3b for supplying a power supply voltage to the electric bulb 20 are formed. The conductive patterns 3a and 3b are provided on both sides of the insertion hole 2 in the longitudinal direction.

The socket body 10 is made of an elastic material such as rubber, and has a cylindrical shape and a closed lower portion for holding a light bulb. However, there are two holes to pass the conductor of the bulb. A connecting member 40, a board fixing collar 30,
Following the extension assisting member 50, each part is integrally formed with the socket.

As shown in FIG. 1, a pair of wires 2
The conductors 1a and 21b become conductive wires 24a and 24b which are led out of holes in the bottom of the socket body, are bent in opposite shapes on both sides of the connecting portion, and are bent and fixed outside the outer peripheral portion of the socket body.

Auxiliary member 50 extending from above insertion hole 2
When the substrate fixing collar 30 is put on the insertion hole and the auxiliary member 50 is pulled from below the substrate, the connecting member 4
0, the board fixing collar 30 extends and goes under the insertion hole 2. When the extension assisting member 50 is released, the substrate fixing flange 30 returns to its original size and stops at the back side of the insertion hole 2.

The conducting wires 24a and 24b guided along the bottom of the socket body 10 are sandwiched between the bottom of the socket body and the conductive patterns 3a and 3b on the substrate by the contraction of the connecting member 40.

At this time, the lower skirt 42 of the socket body for preventing oxidation is connected to the conductors 24a, 24b and the conductive pattern 3.
a and 3b are sealed, and dust and cigarette smoke are shut out. Preliminary soldering is performed on the conductive pattern surface to increase the contact pressure.

When a rotation-preventing stopper 41 is added, a storage hole is provided in advance so that the stopper is placed on the substrate.

[2] Next, a second embodiment of the present invention will be described with reference to FIG.
Indicated by This is a form in which the light bulb is laid down sideways only with a different shape of the socket body 10, and the mounting and dismounting method is exactly the same as in the first embodiment.

Although the socket body, the connecting member, the board fixing flange and the like are described as rubber-based elastic bodies, the shape,
Regardless of the material as long as the functions are similar.

Although the application to a game machine has been described as an example, the invention can be applied to other electric appliances as long as they use a light bulb.

In addition, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the scope of the invention.

[0020]

According to the present invention, since the connecting member is an excellent elastic body, it is possible to sufficiently absorb the difference in the thickness of the substrate plate depending on the manufacturer.

By attaching the assembly assisting member, assembly with the substrate is very simple.

No pins are required. That is, since there is no soldering, a skilled worker is unnecessary, and there is no assembly failure such as non-lighting.
