Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a terminal pin mounting structure on a circuit board of a pachinko machine.

[0002]

[Prior art]

 Various types of lamps are turned on in the pachinko machine, and a so-called silicon ball is used as the lamp. As shown in FIG. 1, this silicon sphere is composed of a light bulb 1 and a silicon holding member 4 having two through holes 3 for holding the light bulb 1 and penetrating a lead wire 2 and set on a lamp substrate 5. It is mounted on the lamp substrate 5 by inserting the through hole 3 of the holding member 4 into the terminal pin 6, and the lead wire 2 and the terminal pin 6 are in contact with each other for electrical connection. Due to the fact that the terminal pins 6 are inserted into the through holes 3, both of the two terminal pins 6 are required to be erected vertically to the lamp substrate 5. By the way, as shown in FIG. 2, the conventional mounting structure of the terminal pin 6 which is erected on the lamp board 5 includes a terminal portion 7 having a diameter d1, a base portion 8 having a diameter d2, and a tail portion 9 having a diameter d3. Was manually inserted into a mounting hole 11 having a diameter D1 larger than the diameter d1 and smaller than the diameter d2 provided in the conductor portion 10 of the lamp board 5, and the base portion 8 side was soldered and mounted.

Looking at the entire electric system of the pachinko machine, as shown in FIG. 7, in addition to the various lamps 20 described above, a proximity switch 21, an LED 22, a solenoid 23, a main circuit 24, special equipment 25 and There is a power supply 26 for supplying electricity to these, and a relay board 27 is prepared for connecting these to each other. In the conventional relay board 27, as shown in FIG. 8, the housing-attached pins 28 are inserted into the relay board 27.

[0004]

[Problems to be solved by the device]

 In the conventional mounting structure, a person manually inserts the terminal pin 6 into the mounting hole 11, so that the diameter d1 of the terminal portion 7 is smaller than the diameter D 1 of the mounting hole 11 so as to facilitate the work. I was trying. Therefore, when the solder 12 is attached, there is a problem that the terminal portion 7 is inclined and attached to the lamp base plate 5. It is possible to use a jig to prevent the inclination, but there is a disadvantage that the workability is extremely deteriorated. Also, since there is a gap between the terminal part 7 and the mounting hole 11, if the base part 8 is turned down, it will fall out, so automation such as dipping in a solder bath and soldering cannot be performed, and manual work with a soldering iron is not possible. I had to resort to. As for the relay board 27, since the pins 29 are provided with the housing 30, the space efficiency is poor and the relay board 27 itself is inevitably large.

Therefore, an object of the present invention is to provide a lamp board of a pachinko machine in which the terminal portion 7 is vertically attached to the lamp board 5 without using a jig, and further automatic soldering is possible by an automatic machine. It is to provide a terminal pin mounting structure, and further to provide a small relay board.

[0006]

[Means for Solving the Problems]

 The present invention for achieving the above object comprises a board having a mounting hole having a diameter D in a conductor portion and a terminal pin having a diameter d equal to or slightly larger than the diameter D. The terminal pin is forced into the mounting hole. The present invention relates to a terminal pin mounting structure on a circuit board of a pachinko machine, which is formed by soldering the terminal pin and a conductor portion in a state of being inserted into the terminal.

[0007]

[Operation and effect of the device]

 By eliminating the gap between the terminal part of the terminal pin and the mounting hole of the lamp board, the terminal part does not tilt with respect to the lamp board when soldering, and the terminal pin does not fall off from the lamp board. Since there is no soldering, automatic soldering by an automatic machine is possible. Moreover, since only the pins are directly inserted into the substrate, the housing is not required and the space efficiency can be improved.

First Embodiment Next, a terminal pin mounting structure according to a first embodiment of the present invention will be described with reference to FIG. In the terminal pin mounting structure of FIG. 3, the diameter D2 of the mounting hole 11 is configured to be slightly smaller than the diameter d1 of the terminal portion 7 or slightly smaller, and the terminal portion 7 is pushed into the mounting hole 11 with force. Needless to say, workability is increased by mechanically inserting by an automatic insertion machine.

Since the lamp substrate is usually made of an organic resin-based member and the terminal portion 7 is made of metal, the terminal portion 7 is pushed in while deforming the organic resin-based member, and after being pushed in, the mounting hole 11 is formed. Since the portion of the terminal portion 7 in contact with the inner peripheral surface of the mounting hole 11 is in close contact, it is held in that state. After that, the base 8 side is soldered.

Since the mounting hole 11 and the terminal portion 7 are in close contact with each other, the terminal portion 7 does not tilt with respect to the lamp substrate 5 even when soldered.

Second Embodiment Next, a terminal pin mounting structure according to a second embodiment of the present invention will be described with reference to FIG. In the terminal pin mounting structure shown in FIG. 4, the diameter d4 of the portion of the terminal portion 7 in contact with the mounting hole 11 is equal to or slightly larger than the diameter D1 of the mounting hole 11 provided in the conventional lamp board 5, and is a large diameter terminal portion. 13, the terminal portion 7 is pressed into the mounting hole 11 by applying force, and then the base portion 8 side is soldered.

Also in this case, since the mounting hole 11 and the large-diameter terminal portion 13 are in close contact with each other, the terminal portion 7 does not tilt with respect to the lamp board 5 even when soldered, and the conventional There is an effect that the lamp substrate can be used as it is. Further, since the contact area between the mounting hole 11 and the large-diameter terminal portion 13 is wide, the verticality is increased.

Third Embodiment Next, a terminal pin mounting structure according to a third embodiment of the present invention will be described with reference to FIG. In the terminal pin mounting structure of FIG. 5, as in the second embodiment, the diameter d4 of the portion of the terminal portion 7 in contact with the mounting hole 11 is equal to the diameter D 1 of the mounting hole 11 provided in the conventional lamp board 5. The large diameter terminal portion 13 is slightly larger. However, the base and tail are not formed.

For mounting, the terminal pin 6 is pushed into the mounting hole 11 from the large-diameter terminal portion 13 side or the terminal portion 7 side by applying force. Also in this case, since the mounting hole 11 of the lamp board made of an organic resin material is deformed and pushed in, the mounting hole 11 and the large-diameter terminal portion 13 come into close contact with each other, and the state is maintained after being pushed. The terminal portion 7 does not tilt even after soldering.

When mounting, the pushing direction can be from the large diameter terminal portion 13 side, so by placing the solder surface on the lower side and arranging the terminal pin automatic insertion machine above, the terminal pin can be inserted and soldered by the solder bath. It is possible to automate such work.

Fourth Embodiment Next, a terminal pin mounting structure according to a fourth embodiment of the present invention will be described with reference to FIG. The terminal pin mounting structure of FIG. 6 is configured such that the diameter D2 of the mounting hole 11 is equal to or slightly smaller than the diameter d1 of the terminal portion 7 as in the first embodiment. However, the base and tail are not formed.

For attachment, the terminal pin 6 is pushed in by applying force from the side of the attachment hole 11 where the conductive portion 10 is not formed, or from the side of the conductive portion 10. Also in this case, since the mounting hole 11 portion of the resin board made of a resin-based member is pushed in while being deformed, the mounting hole 11 and the terminal portion 7 come into close contact with each other, and the state is maintained after being pushed in. Even if it is done, the terminal portion 7 does not tilt.

When mounting, the pushing direction can be from the side where the conductive part 10 is not formed. Therefore, by placing the solder pin on the bottom and arranging the terminal pin automatic inserter on the upper side, it is possible to insert the terminal pin and use the solder bath. Work such as soldering can be automated.

Further, since the terminal pin 6 can have a single diameter, the terminal pin before mounting can be used as a wire rod, and in an automatic insertion machine, cutting-insertion or insertion-cutting can be automated. You can increase efficiency.

Next, a process of automatically inserting a terminal pin according to a fifth embodiment of the present invention will be described with reference to FIGS. 9 to 12. FIG. 9 shows a process in which the terminal pin wire 41 having the constricted portion 40 formed at a desired length position is cut by the cutter 42.

The terminal pin 43 cut in FIG. 9 is inserted into the substrate 27 by the receiving member 44 and the pressing member 45 as shown in FIGS. At this time, as described in the above embodiment, the board 27 is provided with the mounting hole 46 having a diameter equal to or slightly smaller than the diameter of the terminal pin 43.

FIG. 12 shows a sixth embodiment in which the bent terminal pin 53 is inserted. In the case of the bent terminal pin 53, it is the same as the fifth embodiment until the terminal pin wire 51 having the constricted portion 50 is supplied to the insertion machine, but is cut by a cutter (not shown). Before that, a step of bending the pin is added. After bending, it is cut by a cutter, and thereafter, it is inserted into the substrate by a receiving tool and a pressing tool as in the fifth embodiment.

FIG. 13 shows a state of the relay board in which the terminal pins are inserted according to the present invention. As is clear from a comparison between FIG. 8 and FIG. 13, according to the present invention, the housing of the terminal pin is not required, so that the relay board itself can be made small.

FIG. 14 is an explanatory view showing a state where a connector is connected to the terminal pin, and the connector 60 is held by the housing 61.
