[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 inside of a board or a decorative panel in order to enhance the playing effect and give instructions on how to play. I'm trying to go out through the makeup panel. As the light bulb, a so-called silicon light bulb that is easy to install and remove is often used.

In this silicon light bulb, a portion corresponding to the base is made of silicon rubber, and a pair of pins on the circuit board are inserted into the silicon rubber portion to perform wiring and attachment to the circuit board. .

Each pin on the circuit board is inserted into a pin insertion hole formed in the circuit board,
In that state, it is previously soldered and connected to the conductive pattern on the circuit board. This soldering connection is a work in which the pins are supported one by one with fingers or tweezers. Repeating this work for all pins is time-consuming, time-consuming, and very inefficient. In particular, since a large number of light bulbs are used in game consoles and pachinko machines, the time and effort required for soldering work will be enormous.

Further, during the soldering work, there is a risk that the soldering tool may hit the light bulb to damage the light bulb, or the heat of the soldering may melt the silicon rubber. The present invention takes the above circumstances into consideration, and the purpose thereof is to easily and quickly attach and connect a light bulb to a substrate without requiring soldering work, thereby improving work efficiency. The present invention is intended to provide a light bulb mounting device capable of eliminating damage to a light bulb and melting of parts.

[0006]

A pair of first elastic members that elastically deform, and a first elastic member formed on the first elastic members that are pressed against the insertion hole with a restoring force generated by the elastic deformation of the first elastic member, and are pressed from the peripheral edge of the insertion hole to one of the substrates. The step-shaped portion that contacts the surface and the outer peripheral surface of the socket body are provided at positions opposite to each other with the socket body interposed therebetween, and the stepped portion is inserted into the insertion hole from the other surface side of the board. By doing so, it elastically deforms so as to spread in the direction opposite to the socket body side while contacting the other surface of the substrate, and the restoring force generated by this elastic deformation causes the socket body to be attached to the side opposite to the insertion direction. A pair of second elastic members that give a force, and are guided from the light bulb through the socket body to the step-shaped portions of the first elastic members or the second elastic members, and the step-shaped portions and one surface of the substrate. And a pair of conductive wires that are sandwiched between the second elastic members and the other surface of the substrate and are in contact with the conductive pattern on the substrate.

[0007]

In the light bulb mounting apparatus of the present invention, when the socket body is inserted into the insertion hole from the other surface side of the substrate, each first elastic member is elastically deformed by the insertion, and the elastic deformation is generated. With the restoring force, each step-shaped portion is pressed against the insertion hole and is in contact from the peripheral edge of the insertion hole to one surface of the substrate.
Further, upon insertion, each second elastic member elastically deforms while contacting the other surface of the substrate, and the restoring force generated by the elastic deformation applies a biasing force to the socket body in the direction opposite to the insertion direction. By this biasing force, each step-shaped portion is pressed against one surface of the substrate, and each second elastic member is pressed against the other surface of the substrate. The socket main body is held on the substrate by the pressure contact action of facing each other with the substrate sandwiched therebetween. Further, due to the double-pressing action, the pair of conducting wires guided to each step-shaped portion or each second elastic member directly contacts the conductive pattern on the substrate.

【Example】

[1] Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. In FIG. 4, reference numeral 1 is a circuit board. An insertion hole 2 having a substantially elliptical shape is formed at an arbitrary position on the circuit board 1.
Is formed.

On the lower surface (one surface) of the circuit board 1, a pair of conductive patterns 3a, 3b for supplying a power supply voltage to the light bulb 2 described later is formed. This conductive pattern 3a, 3
b extend along the diameter of the elliptical shape of the insertion hole 2 in the longitudinal direction, and are in contact with the edge of the insertion hole 2.

The conductive patterns 3a and 3b are provided in the insertion hole 2
It suffices that it is formed in the vicinity of, and it is not always necessary to contact the edge of the insertion hole 2. As shown in FIGS. 1, 2 and 3.
A socket body 10 is prepared that is attached to the circuit board 1.
The socket body 10 is formed into a cylindrical shape by an elastic member such as plastic and can be inserted into the insertion hole 2, one end portion along the axial direction is closed, and the other end portion is opened.

A hole for accommodating a light bulb is formed in the socket body 10 from the opening at the other end to the inside, and the light bulb 20 is inserted and fitted therein. With this fitting,
The elasticity of the socket body 10 holds the light bulb 20.

The bulb 20 has a pair of internal conductors 21a and 21b, a filament 22 connected to the internal conductors 21a and 21b, and a support wire 23 for supporting the filament 22 in a glass bulb, and a bottom portion. Lead wires 24a and 24b, which will be described later, are derived from. This conductor 2
4a and 24b are connected to the internal conductors 21a and 21b.

A pair of first elastic members 30a, 30b are provided on the outer peripheral surface of the socket body 10 on the one end side at positions facing each other with the socket body 10 interposed therebetween. The elastic members 30a and 30b are made of the same material as the socket body 10 and are actually integrally formed with the socket body 10. The elastic members 30a and 30b once project outward from one end of the socket body 10,
It has a substantially L-shape that is bent so as to slightly expand obliquely toward the other end side of the socket body 10. Then, stepped portions 31a and 31b are formed at the tips of the elastic members 30a and 30b.

The step-shaped portion 31 a stands on the surface of the insertion hole 2 which is in contact with the lower surface of the circuit board 1 and stands upright in a substantially perpendicular direction (axial direction of the socket body 10). And a standing portion 33 that can be pressed. Step portion 31
Similarly, b also has an interview portion 32 and a rising portion 33.

Further, as shown in FIGS. 5 and 6, a lead wire accommodating groove 34 is formed from the bottom of the socket body 10 to the outer surface of the elastic member 30a. Further, the elastic member 3
The wire engaging groove 35 is formed in the upright portion 33 of the stepped portion 31a at the tip of 0a. Similarly, the elastic member 30b is also formed with a conductor receiving groove 34 and a conductor engaging groove 35.

The outer diameter r ₁ of the socket body 10 is slightly smaller than the diameter of the insertion hole 2 in the lateral direction of the ellipse,
The distance r ₂ between the base ends of the elastic members 30a and 30b is slightly smaller than the diameter of the insertion hole 2 in the longitudinal direction of the elliptical shape.

As shown in FIG. 7, the lead wires 24a and 24b led out from the bottom portion of the light bulb 20 pass through the lead wire insertion holes 12a and 12b at the bottom portion of the socket body 10, and the socket body 1
Guided out of 0.

A lead wire 24 led to the outside of the socket body 10.
a and 24b are elastic members 3 from the bottom of the socket body 10.
0a, 30b, respectively, are accommodated in the conductor wire accommodation grooves 34, hooked in the conductor wire engagement grooves 35, and routed to the inside of the upright portion 33. By this routing, the conductive wires 24a and 24b pass over the surface contact portions 32 of the step-shaped portions 31a and 31b so as to traverse along the radial direction of the socket body 10.

On the other hand, on the outer peripheral surface of the socket body 10 on the other end side, a pair of members are provided at positions facing each other with the socket body 10 interposed therebetween, and in a direction substantially orthogonal to the facing direction of the first elastic members 30a, 30b. Second elastic members 40a and 40b are provided.

The elastic members 40a and 40b are made of the same material as the socket body 10 and are actually integrally formed with the socket body 10 like the elastic members 30a and 30b.
It has a tongue shape that projects from the other end side of the socket body 10 and hangs down in the diagonal direction of the one end side. Then, planar contact portions 41 that can contact the upper surface (the other surface) of the circuit board 1 are formed at the tips of the elastic members 40a and 40b.

In this manner, the circuit board 1 and the socket body 10 constitute a light bulb mounting device for mounting and connecting the light bulb 20 to the circuit board 1. In actual mounting and connection, the socket body 10 is held by fingers from the side of the light bulb 20, and the positions of the elastic members 30a and 30b are aligned with the elliptical longitudinal direction of the insertion hole 2. Then, one end side of the socket body 10 is inserted into the insertion hole 2 from the upper surface side of the circuit board 1 as shown by an arrow in FIG.

At the time of this insertion, the elastic members 30a, 30b
While its outer surface hits the insertion hole 2, it is elastically deformed so as to be narrowed toward the socket body 10. Due to this elastic deformation,
The tips of the elastic members 30a, 30b, that is, the step-shaped portions 31a,
A restoring force is generated in 31b in the direction indicated by the thick arrow in FIG. 7, that is, in the direction opposite to the socket body 10 side.

When the insertion proceeds by a predetermined amount, the step-shaped portions 31a, 3a
1b presses the insertion hole 2 with the restoring force, and contacts from the peripheral edge of the insertion hole 2 to the lower surface of the substrate 1. That is, the raised portions 33 of the step-shaped portions 31 a and 31 b are in pressure contact with the peripheral surface of the insertion hole 2, and the contact portions 32 are in contact with the lower surface of the circuit board 1.

As shown in FIG. 8, the elastic members 40a and 40b, on the other hand, spread in the direction opposite to the socket body 10 side while the contact portions 41 contact the upper surface of the substrate 1 as shown in FIG. Elastically deforms. Due to this elastic deformation, a force in a direction indicated by a thick line arrow in FIG. 8, that is, a restoring force to the circuit board 1 side is generated in the elastic members 40a and 40b themselves. Due to this restoring force, a biasing force is applied to the socket body 10 in the direction opposite to the insertion direction.

When a biasing force is applied to the socket body 10 in this manner, the face-to-face contact portion 32 of each of the step-shaped portions 31a and 31b.
Is pressed against the lower surface of the circuit board 1 and the elastic member 4
The contact portions 41 of 0a and 40b are pressed against the upper surface of the circuit board 1. The socket body 10 is held on the circuit board 1 by the two pressure contact actions that face each other with the circuit board 1 interposed therebetween.

FIG. 2 is an oblique view of this state, and FIG. 3 is a bottom view of the circuit board 1. At this time, the conductor wires 24a and 24b guided to the surface contact portions 32 of the step-shaped portions 31a and 31b under the action of both pressure contact are sandwiched between the respective surface contact portions 32 and the lower surface of the circuit board 1. Conductive patterns 3a and 3b are provided at the sandwiched positions.
Therefore, the conductive wires 24a and 24b are electrically conductive patterns 3
Direct contact with a and 3b.

That is, the conductive patterns 3a and 3b and the light bulb 2
The internal conductors 21a, 21b of 0 are electrically connected to each other via the conductors 24a, 24b, and thus the conductive patterns 3a, 3b.
By applying the power supply voltage in between, the light bulb 20 is turned on.

In this way, the socket body 10 is inserted into the insertion hole 2
The socket body 10 is held on the circuit board 1 by a simple operation just by inserting it into the circuit board 1, and at the same time, the connection between the light bulb 20 and the conductive patterns 3a and 3b is completed, so that the conventional soldering work is unnecessary. Become.

When the soldering work becomes unnecessary, the light bulb 20
The labor and time required for installation and connection of are greatly reduced, the burden on the worker is lightened, and the work efficiency is improved. As a result, the production amount can be increased and the cost can be reduced. This improvement in work efficiency is particularly remarkable in game machines such as a game machine and a pachinko machine where a large number of light bulbs are used.

Moreover, if the soldering work becomes unnecessary,
The damage of the light bulb 20 by the soldering tool is eliminated, and the problem that the parts are melted by the heat of soldering is also solved. On the circuit board 1, including the circuit board 1, there are many parts such as electric wires, resistors, capacitors, integrated circuit chips that are easily melted by heat, so that soldering work becomes unnecessary in terms of safety protection of parts. Greatly effective.

Further, as shown by the chain double-dashed line in FIG. 7, by putting a finger on the other end of the socket body 10, the socket body 1
When 0 is pressed so as to be inclined along the longitudinal direction of the elliptical shape of the insertion hole 2, the socket body 10 can be removed from the circuit board 1.

That is, when the socket body 10 is pressed so as to be inclined toward the elastic member 30b side along the elliptical longitudinal direction of the insertion hole 2, elastic deformation occurs from the bottom of the socket body 10 to the elastic member 30b (outer periphery of the socket body 10). Deformation that reduces the distance Lb between the surface and the stepped portion 31b)
From the bottom of the socket body 10 to the elastic member 3
0a causes elastic deformation (deformation in which the distance La between the outer peripheral surface of the socket body 10 and the step-shaped portion 31a increases).

Due to this elastic deformation, the upright portion 33 of the step-shaped portion 31b is pulled out from the insertion hole 2 to the lower surface side of the circuit board 1, and the surface contact portion 32 of the step-shaped portion 31a is inserted into the insertion hole 2. When the socket body 10 is further tilted in this state, the locking action of the step-shaped portions 31a and 31b is released,
The entire socket body 10 can be pulled out to the upper surface side of the circuit board 1.

Needless to say, the socket body 10 can be detached from the circuit board 1 in the same manner when it is tilted toward the elastic member 30a. Thus, the socket body 10 can be detached from the circuit board 1 only by tilting the socket body 10 to one side with one finger (for example, the index finger). Therefore, when the light bulb 20 breaks down, the light bulb 20 can be easily and quickly replaced with a new one.

In a game machine or a pachinko machine, since the lighting time of the light bulb 20 is long, it is easy to replace the light bulb 20 that has reached the end of its life. Where there are many game machines and pachinko machines installed, maintenance work such as bulb replacement tends to become more and more busy.

Under such circumstances, the socket body 1
Immediate removal of 0 from the circuit board 1 has a great effect in simplifying maintenance work. Needless to say, soldering work is not required when the socket body 10 is attached to the circuit board 1 again in this maintenance work.

[2] Next, a second embodiment of the present invention will be described with reference to FIG.
And shown in FIG. In the second embodiment, the elastic member 30
In the step-shaped portions 31a and 31b of a and 30b, the height of each standing portion 33 is made larger than the thickness of the substrate 1,
When the mounting is completed, the rising portion 33 passes through the insertion hole 2 and largely projects from the upper surface of the circuit board 1. The other structure is the same as that of the first embodiment.

According to this structure, the socket body 1
There is an advantage that the work of removing 0 from the circuit board 1 is easy and the holding action for the socket body 10 is strong.

That is, as shown by the chain double-dashed line in FIG.
When both upright portions 33 protruding to the upper surface side of the circuit board 1 are sandwiched and held by two fingers (for example, an index finger and a thumb), elastic deformation from the bottom of the socket body 10 to the elastic member 30a (the outer peripheral surface of the socket body 10 and A deformation such that the distance La between the stepped portion 31a and the stepped portion 31a is reduced occurs, and an elastic deformation from the bottom portion of the socket body 10 to the elastic member 30b (the distance between the outer peripheral surface of the socket body 10 and the stepped portion 31b). Deformation such that Lb shrinks occurs. If the socket body 10 is lifted up as it is, the stepped portion 31a,
31b enters the insertion hole 2 and the entire socket body 10 can be pulled out to the upper surface side of the circuit board 1.

Therefore, when the dehumidifying operation of the light bulb 20 is abnormal, the light bulb 20 can be replaced with a new one easily and quickly. Further, since the stepped portions 31a and 31b are forcibly inserted into the insertion hole 2 by sandwiching both the upright portions 33, the diameter of the insertion hole 2 in the longitudinal direction of the elliptical shape is the same as that of the first embodiment. It can be smaller than the case. Therefore, the gap between the socket body 10 and the insertion hole 2 is reduced, and firm holding without "rattle" can be performed.

[3] A third embodiment of the present invention will be described with reference to FIG. In the third embodiment, one end of the socket body 10 is opened and the other end is closed. Then, the electric bulb 20 is inserted from the opening on the one end side of the socket body 10 and fitted and held.

That is, the conductor 24a is the socket body 1
No. 0 is once ejected from the closed surface on the other end side, and then inserted again into the closed surface on the other end side and pulled out to the notch 36 on the side of the elastic member 30a. Then, the conductor wire 24a drawn out to the cutout portion 36 is reinserted into the cutout portion 36 and drawn out to one end side of the surface contact portion 32 of the step-shaped portion 31a, and from there to the other end side of the surface contact portion 32, the surface contact portion 32a. It is crawled over 32 along the circumferential direction of the socket body 10. Then, the tip of the conductive wire 24a is bent from the other end side of the surface contact portion 32 to the side surface of the elastic member 30a.

Although not visible in the figure, the elastic member 30b also has a cutout portion 36 on the side thereof, so that the lead wire 24b can be routed from the other end of the socket body 10 to the elastic member 30b in the same manner as the lead wire 24a. Done.

[0081]

As described above, according to the present invention, each first elastic member is elastically deformed by the insertion of the socket body into the insertion hole, and the stepped portion is inserted into the insertion hole by the restoring force generated by this elastic deformation. The second elastic member is elastically deformed while being pressed against the peripheral surface of the insertion hole to one surface of the substrate, and the second elastic member is elastically deformed while being in contact with the other surface of the substrate. A biasing force is applied to the opposite side of the substrate, and this biasing force presses the stepped portion against one surface of the substrate and the second elastic member against the other surface of the substrate. The socket main body is held on the substrate by both pressure contact actions facing each other, and with this holding, the pair of conductive wires guided to each step-shaped portion or each second elastic member comes into contact with the conductive pattern on the substrate. As a result, it is possible to easily and quickly attach and connect the bulb to the board without the need for soldering work, which improves work efficiency and eliminates damage to the bulb and melting of parts. It is possible to provide a bulb mounting device that can be used.
