Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a circuit board housing which is disposed on the back side of a pachinko machine and protects a circuit board on which electronic components used in the pachinko machine are mounted. It is about a box. 2. Description of the Related Art In recent years, pachinko machines are equipped with a wide variety of ICs.
Although electronic components such as LSIs have been adopted, these electronic components must be protected from various operations on the back side of the pachinko machine, and must be protected from dust and the like. Must. For this reason, conventionally, such electronic components as described above have been put together on a circuit board and stored in a storage box arranged and fixed on the back side of the pachinko machine. The storage box has a structure for simply supporting and storing the circuit board. However, in view of the actual situation of the pachinko machine, simply storing the circuit board on which the electronic components are mounted in the box is not sufficient. That is, a large number of electric wires must be connected to the circuit board, and this connection is made by inserting a connector having a large number of electric wires into a connector on the circuit board side. At the time of this insertion, a large force is applied to the circuit board, but this force causes the circuit board to bend or break, resulting in poor electrical connection between the wiring pattern on the circuit board and the electronic components. In addition, there is a problem that the wiring pattern on the circuit board is disconnected in some cases. SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and has as its object to provide a method for providing a defective electrical connection or disconnection even when a force is applied to a housed circuit board. An object of the present invention is to provide a box for storing a circuit board in a pachinko machine that can reliably prevent such an accident. [0005] In order to achieve the above object, a circuit board storage box according to the present invention will be described with reference to the drawings corresponding to the embodiments. The box 10 is disposed and fixed on the back side of the pachinko machine, and has a main body 11 for supporting the whole of a single circuit board 20 having substantially the same shape as the bottom surface by floating from the bottom surface, and being supported by being floated in the main body 11. And a cover 13 covering a portion on which electronic components are mounted except for the connector portion 21 which is narrowly unevenly distributed on one side of the circuit board 20. The supporting projection 1 as a supporting portion for supporting the back surface of the connector portion 21 of the circuit board 20 so that a part of the circuit board 20 is not deformed when the connector 23 provided at the tip is pressed and connected in the vertical direction. 2 is provided on the main body 11. With the above-described configuration, the circuit board 20 is housed in the space formed by the main body 11 and the lid 13, and as shown in FIG. The back surface of the portion where the portion 21 is formed is in a state where it can be supported by the supporting projection 12 as a supporting portion on the main body 11. Accordingly, when a connector 23 having a large number of wirings 22 connected thereto is inserted into the connector portion 21 from the vertical direction, even if a force is applied to the connector portion 21 on the circuit board 20 side, the circuit board 2
Since the reference numeral 0 is supported by the supporting projections 12, the circuit board 20 does not bend or break, and it is possible to reliably prevent an accident such as poor electrical connection or disconnection on the circuit board 20. . Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a circuit board storage box 10 according to the present invention. As shown in FIG. 3, the circuit board storage box 10 mainly includes a main body 11 and a lid fitted and fixed thereto. It consists of body 13. The circuit board storage box 10 is disposed at a predetermined location on the back side of the pachinko machine 1 by fixing the main body 11 to the back side of the pachinko machine 1 as shown in FIG. As described above, the circuit board 20 is housed in the space defined by the main body 11 and the lid 13. 3 and FIGS. 10 to 12
As shown by, a pair of support projections 12 are integrally formed as support portions at a lower portion of the drawing. Each of these supporting projections 12 is located on the back side of the connector portion 21 on the circuit board 20 side, and receives this force when a force is applied to the circuit board 20 via the connector portion 21. is there. Further, one circuit board 20 having substantially the same shape as the bottom shape of the main body 11 is provided at the four inner corners on the main body 11.
A mounting boss 11a is provided so as to float and secure. Note that, in the present embodiment, each support protrusion 12
Although formed integrally with the main body 11, it may be formed separately and provided, or may have any structure as long as it also supports the shape. As shown in FIGS. 7 to 9, the lid 13 has a circuit board 20 and a storage portion suitable for storing various electronic components mounted thereon.
It comprises a plate-like portion 13a for covering a portion on which electronic components are mounted except for the connector portion 21 which is narrowly unevenly distributed on one side, and an opening window 13b for opening the upper portion of the connector portion 21. In the embodiment, an air vent hole 13c is formed in the upper surface of the lid 13. Further, by extending the left and right side walls of the lid 13 downward in the figure, as shown in FIGS.
It is assumed to be 4. These protective walls 14 are shown in FIG.
As shown in the figure, the connector protects the connector unit formed by integrating the connector unit 21 on the circuit board 20 side and the connector 23 on the wiring 22 side. Of the size. As shown in FIGS. 1 and 4, a storage recess 15 is formed on the right side of the lid 13 in the drawing. The storage recess 15 is formed by forming a step 15a on the right side of the lid 13 and projecting protrusions 15b on both upper and lower ends of the step 15a. Note that the storage recess 15 can be formed and implemented as a vertically continuous groove. However, as in the present embodiment, it is more preferable that the storage recess 15 is formed by the step portion 15a and the upper and lower protrusions 15b. Thus, a gap for inserting a finger or the like can be formed, and work such as taking out the wiring 22 in the storage recess 15 can be performed more favorably. In the circuit board housing box 10 configured as described above, the circuit board 20 is housed in a space formed by the main body 11 and the lid 13, as shown in FIG. In particular, the back surface of the portion where the connector portion 21 is formed can be supported by the supporting projections 12 on the main body 11. In other words, even if the connector portion 21 of the circuit board 20 has been floated from the support projection 12, the connector portion 21 can be supported by the support projection 12 because of the presence of the support projection 12 below it. It is. Thus, when a connector 23 having a number of wirings 22 connected thereto is inserted from the vertical direction, even if a force is applied to the connector 21 on the circuit board 20 side, the circuit board 20 is Since the circuit board 20 is supported by the support projections 12, the circuit board 20 is not bent or damaged, and an accident such as a failure in electrical connection on the circuit board 20 or disconnection can be reliably prevented. The connector 21 on the circuit board 20 side
When the connector 23 on the side of the wiring 22 is inserted into the connector part 21, as shown in FIG. 2, both sides of the connector part 21 are particularly protected by the protective walls 14 integrally formed on the lid 13. Thus, when a pachinko parlor clerk or the like performs various operations around the circuit board storage box 10, the tools and the body are prevented from directly contacting the connector portion 21 or the connector 23. Therefore, there is no possibility that a contact failure between the two connector portions 21 and the connector 23 occurs, and the other connector 23 does not come off from the one connector portion 21. Further, as shown in FIG. 2, a large number of wirings 22 are provided in storage recesses 15 of circuit board storage box 10.
It is housed in a centralized state. This allows
