BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lamp mounting structure, and more particularly to a lamp mounting structure suitable for a lamp used in 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, 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.

[0004]

Since the conventional structure requires the work of planting the terminal pins 6 on the lamp substrate 5,
Since the terminal pins and the process of arranging them have been required, the cost was increased due to the number of parts and the process, workability was poor, and the verticality was uneven. Therefore, the present applicant proposes to solve the disadvantages of the conventional structure in Japanese Patent Application No. 5-22.
Proposed No. 9693.

Therefore, an object of the present invention is to eliminate the need for a terminal pin and to propose the above-mentioned Japanese Patent Application No. 5-229 proposed by the present applicant.
It is to provide a more inexpensive lamp mounting structure than No. 693, and further to provide a lamp mounting structure that can be automatically mounted by an automatic machine.
