Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lamp mounting structure for a pachinko machine.

[0002]

2. Description of the Related Art In a pachinko machine, various lamps are turned on. As the lamp, a so-called silicon ball is used. This silicon sphere has a holding member 4 made of silicon having a light bulb 1 and two through holes 3 for holding the light bulb 1 and penetrating a lead wire 2 as shown in FIG.
The lamp board 5 is formed by inserting the through hole 3 of the holding member 4 into the terminal pin 6 that is planted on the lamp board 5.
The lead wire 2 and the terminal pin 6 come into contact with each other while being mounted on the upper surface, so that they are also electrically connected.

As described above, in the conventional device, first, the terminal pins 6 must be set up on the lamp substrate 5, which is a disadvantage. In addition, because the terminal pins 6 are inserted into the through holes 3, both of the two terminal pins 6 are required to be vertically arranged with respect to the lamp substrate 5, and therefore, as shown in FIG.
As shown in FIG. 4, the terminal pin 6 including the terminal portion 7 having the diameter d1, the base portion 8 having the diameter d2, and the tail portion 9 having the diameter d3 is larger than the diameter d1 provided on the conductor portion 10 of the lamp substrate 5 and smaller than the diameter d2. A person manually inserted it into the mounting hole 11 having the diameter D1 and soldered the base portion 8 side for mounting.

[0004]

Since the conventional structure requires the work of planting the terminal pins 6 on the lamp substrate 5,
The terminal pin and its planting process were required, leading to cost increase due to the number of parts and process, and workability was also poor.

Therefore, an object of the present invention is to provide a lamp mounting structure which eliminates the need for terminal pins.
(EN) A lamp mounting structure for a pachinko machine that can be automatically mounted by an automatic machine.

[0006]

A holding member for holding a lamp and having a through hole for drawing out a lead wire of the lamp to the outside, and a lamp machine plate provided with an insertion hole having a size into which the holding member can be inserted. A conductor part connected to the wiring path on the surface of the lamp substrate is formed on the inner wall of the insertion hole, and the lead wire pulled out to the outside of the holding member is sandwiched between the outer wall of the holding member and the conductor part of the inner wall of the insertion hole. According to the lamp mounting structure in the pachinko machine, the holding portion is inserted into the insertion hole.

[0007]

According to the present invention, the inner wall of the insertion hole of the lamp substrate serves as a conductor electrically connected to the wiring path on the surface of the lamp substrate, and the lead wire of the lamp is compressed and sandwiched between the lamp holding member and the inner wall of the insertion hole. Since it is electrically connected to the conductor part, the terminal pin is unnecessary, the terminal pin erection process is unnecessary, and the soldering between the terminal pin and the wiring path of the lamp board is also unnecessary. A lamp mounting structure for a pachinko machine can be obtained.

Further, by making the cross section of the outer periphery of the holding member and the insertion hole oval, the relative positions of the two in the circumferential direction do not shift, so that the positions of the lead wire and the conductor portion can be surely aligned. The inconvenience that the lead wire is inadvertently positioned in the non-conductor portion is eliminated. This is because the holding member does not rotate even by an unnecessary external force after the insertion and attachment, so that the above inconvenience does not occur even after the attachment.

Furthermore, the holding member is provided with two legs,
By making the cross section of the insertion hole into a megger shape, the degree of freedom of the lead-out position in the circumferential direction of the lead wire is increased as compared with the cross section having an elliptical cross section. Also in this case, since the holding member does not rotate due to unnecessary external force after attachment, inconvenience such as contact failure does not occur.

Furthermore, by providing the holding member with two legs and independently providing two insertion holes into which the two legs of the lamp board can be inserted, the non-conductor portion is provided on the conductor portion of the inner wall of the insertion hole. Since it is not necessary to provide the lead wire, the lead wire may be drawn out anywhere, and the lead wire drawing position need not be aligned, which has the effect of increasing workability. Of course, also in this case, since the holding member does not rotate due to an unnecessary external force after the mounting, there is an effect that the mounting becomes robust.

[0011]

First Embodiment FIGS. 3 to 5 show an example of a holding member having a circular cross section. FIG. 3 shows a state before the holding member 4 holding the lamp 1 is inserted into the lamp substrate 5. The holding member 4 is made of a silicone resin and has slits 20 provided at two positions at 180 ° intervals in the circumferential direction.

The lamp board 5 is provided with an insertion hole 21 into which the holding member 4 is inserted, and the insertion hole 21 has an inner wall 22.
It is a so-called through-hole substrate in which a conductor portion 24 electrically connected to the wiring path 23 on the surface of the lamp substrate is formed. However, the non-conductor portions 25 are formed at two places at intervals of 180 degrees in the circumferential direction, and the wiring paths 23 on the surface of the lamp substrate shown in FIG.
The conductor portions 24a and 24b are electrically connected to a and 23b, respectively.

FIG. 5 shows a state in which the holding member 4 is inserted into the insertion hole 21 of the lamp board 5. The holding member 4 is inserted into the lamp substrate 5 by bending the lead wire 2 penetrating the through hole 3 of the holding member 4 along the outer peripheral wall 26 of the holding member 4. At the time of insertion, since the holding member 4 is deformed and is inserted into the insertion hole 21 due to the presence of the slit 20, the insertion state becomes solid.

When the retaining member 4 is inserted into the insertion hole 21 of the lamp substrate 5 in this way, the lead wire 2 is compressed and sandwiched between the lamp holding member 4 and the inner wall 22 of the insertion hole as shown in FIG. , The lead wire 2 is electrically connected to the conductor portion 24.

Next, a horizontal structure for mounting a lamp according to a second embodiment of the present invention will be described with reference to FIGS. 6 and 7. The second embodiment is the same as the first embodiment except that the shape of the cross section of the holding member 4 is elliptical, and therefore description thereof is omitted. However,
In the case of the second embodiment, as is apparent from FIG. 7, since the holding member 4 and the insertion hole 21 are elliptical, they do not rotate after insertion and attachment, even if unnecessary force is applied, so that rotation does not occur.
There is no inconvenience that the lead wire 2 moves to the position of the non-conductor portion 25 and the electrical connection is broken.

Next, referring to FIGS. 8 and 9, the third embodiment of the present invention will be described.
The lamp mounting structure according to the embodiment will be described. As shown in FIG. 8, the lower surface of the holding member 4 has two cylindrical legs 27.
a and 27b are provided.

As shown in FIG. 9, the lamp board 5 is provided with insertion holes 21a and 21b which are sized so that the leg portions 27 of the holding member 4 are fitted therein, and the insertion holes 21a and 21b are communicated with each other. The holes 31 are formed to form eyeglass-shaped insertion holes.

The insertion holes 21a, 21b have inner walls 22,
A so-called through hole is formed by forming a conductor portion 24 electrically connected to the wiring path 23 on the surface of the lamp substrate, but a non-conductor portion 25 is formed on the inner wall 32 of the communication hole.

In order to insert the holding member 4 into the lamp substrate 5, first, the lead wire 2 penetrating through the through holes (not shown) of the respective leg portions 27a and 27b of the holding member 4 is inserted into the leg portions 27a and 27b.
Bend along the outer peripheral wall 26 of 7b. After that, the leg portions 27a and 27b are inserted into the insertion holes 21a and 21b.
As a result, the lead wire 2 is compressed and sandwiched by the outer peripheral wall 26 of the leg portion 27 and the insertion hole 21, and is electrically connected to the wiring path 23 on the surface of the lamp substrate via the conductor portion 24.

Next, referring to FIGS. 10, 11 and 12,
A fourth embodiment of the present invention will be described. The fourth embodiment is different from the third embodiment having the communication hole 31 in that the insertion holes 21a and 21b of the lamp substrate 5 are independently provided, but the shape of the holding member 4 is different. Since it is the same as the third embodiment, the same parts are designated by the same reference numerals and the description thereof is omitted. Since the insertion holes 21a and 21b are independent of each other, the inner walls 22a and 22b of the insertion holes 21a and 21b are formed with conductor portions 24a and 24b over the entire circumference without forming non-conductor portions. There is. The holding member 4 is inserted into the lamp substrate 5 as in the third embodiment, and the inserted state is shown in FIG.

According to the fourth embodiment, no matter where the lead wire 2 is pulled out to the outer peripheral wall 26 of the leg portions 27a and 27b, the wiring path on the surface of the lamp substrate is surely passed through the conductor portions 24a and 24b. It is electrically connected to 23a and 23b.

The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the gist of the present invention. For example, when inserting the holding member into the lamp substrate, the slits are used in the first and second embodiments, and the third,
Although the insertion state is maintained with dimensional accuracy in the fourth embodiment, it goes without saying that slits may be used in the third and fourth embodiments.
