Description

[Detailed Description of the Invention] The present invention relates to an improvement of an electrical component mounting device for a pachinko machine.

Conventionally, the control box, which is an electrical component that houses a printed circuit board on which electronic circuits are mounted to control a pachinko machine, is fixed with screws to a mounting plate provided on the back side of the pachinko machine. , the disadvantage is that it takes time to tighten the screws and the work is troublesome.

The present invention was made in view of the above circumstances, and its purpose is to provide an electrical component mounting device for a pachinko machine that can easily and quickly attach electrical components to a pachinko machine, and that can reduce manufacturing costs. is to provide.

An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a metal control box as an electrical component, and a printed circuit board 2 on which an electronic circuit for controlling the pachinko machine is mounted is housed inside. The connectors 3 and 4 are attached to the protruding portions. Reference numeral 5 denotes a mounting tongue piece formed by cutting and bending the upper and lower side plates (only the upper part is shown) of the control box 1, and a circular mounting hole 6 is provided here. On the other hand, 7 is a mounting plate that is attached to cover the mechanical part on the back side of the pachinko machine, and this is a mounting plate that is attached to the pins 9, 9 of the hinge member 8 fixed to one side of the pachinko machine through the insertion holes ( (not shown), then rotate the lever member 10 provided around the mounting plate 7 and engage it with the engaging portion on the pachinko machine side, thereby attaching it to the back side of the pachinko machine. The mounting plate 7 is made of, for example, plastic, and bosses 11, 11, which are mounting bases that match the mounting holes 6, are integrally formed and protrude from the surface of the mounting plate 7. A pilot hole 12 for a tapping screw is integrally molded on. 13
is a positioning projection protruding from the end surface of the boss portion 11. Now, reference numeral 14 denotes a substantially cylindrical mounting body formed by integral molding of plastic, and the base end of this is attached to a small diameter part 14 through a stepped part 14a on the inner diameter part.
b is provided, and a stepped portion 14c is provided on the outer diameter portion.
A large-diameter portion 14d is provided therebetween. The outer diameter of the portion of the mounting body 14 excluding the large-diameter portion 14d is set to be approximately equal to that of the mounting hole 6, and the large-diameter portion 14d of the mounting body 14 is positioned to have a width approximately equal to that of the convex portion 13. A notch 14e is provided for this purpose. This notch 14e constitutes a mold-cutting recess. Reference numeral 15 denotes an engaging pawl that is integrally molded on the mounting body 14 so as to face the notch 14e. The distal end of the engaging claw 15 is elastically deformable in the inner and outer radial directions of the mounting body 14 by the elastic force of the plastic, and the distal end of the engaging claw 15 has the mounting body 1
A guide surface 15a is formed which is inclined outward from the outer shape of the guide surface 15a. The above-mentioned notch 14e is formed by the engaging claw 15 and the slit hole 1 around it.
It also serves as a die cutting part when forming 6.
The mounting body 14 formed in this manner is attached to the boss portion 11 with the notch portion 14e engaged with the convex portion 13.
and is integrally fixed to the boss portion 11 by screwing the tapping screw 17 into the lower hole 12 through the small diameter portion 14b of the attachment body 14.

When installing the control box 1 to the mounting plate 7 fixed to the back side of the pachinko machine, insert the mounting holes 6 into each tip of the mounting body 14, and then install the control box 1 as is. When pushed in the direction of plate 7, guide surface 15
The engagement claw 15 is elastically deformed in the direction of arrow A, and the mounting tongue 5 rides over the tip of the engagement claw 15 and comes into contact with the large diameter portion 14d, and in this state, the engagement claw 15
The tip of the control box 1 comes off the inner surface of the mounting hole 6 and is engaged with the end surface of the mounting tongue 5 on the periphery of the mounting hole 6, thereby fixing the control box 1 to the mounting plate 7.

In the above configuration, the mounting hole 6 of the control box 1 is connected to the mounting body 1.
Since the installation can be completed by simply pushing it in after penetrating the tip of 4, it can be installed in a shorter time and more easily than in the conventional case where screws are used.

In addition, when manufacturing the mounting body 14, the mounting body 14
Since the notch 14e is provided in the large-diameter portion 14d that is integrally molded on the base side, the engaging pawl 15 can be die-cut through this notch 14e. Therefore, the mold for molding the mounting body 14 may be a simple two-piece mold, which simplifies the mold configuration and reduces manufacturing costs. When attaching the attachment body 14 to the boss portion 11 of the pachinko machine, the cutout portion 14e is fitted into the convex portion 13 of the boss portion 11, so that the position of the attachment body 14 can be determined, and the attachment Work efficiency can be improved. Particularly in this case, since the notch 14e originally used for cutting out the engaging claw 15 is used for positioning, there is no need to provide a separate structure for positioning, and the overall cost can be reduced accordingly.

It should be noted that the present invention can be similarly applied to cases where a printed circuit board is directly attached to a part other than the control box 1, and to various electrical components for pachinko machines such as solenoids and relays. Further, the attachment body 14 may be integrally formed with the boss portion 11.

As is clear from the above description, the present invention can provide an electrical component attachment device for a pachinko machine that allows electrical components to be easily attached to the pachinko machine in a short time.
