Description

[Detailed Description of the Invention] [PROBLEMS TO BE SOLVED] Regarding a printed wiring board combination method, an object thereof is to provide a printed wiring board combination method capable of enlarging the pattern area and facilitating assembly and separation during test / maintenance. In a method of combining printed wiring boards, the female side member having a fitting hole is fixed to one side of the first printed wiring board, and a connecting member having a notch is temporarily fixed to the opposite side. At the same time, a male side member having a fitting protrusion that fits into the fitting hole of the first printed wiring board is fixed to one corresponding side of the second printed wiring board, and the fitting protrusion is fitted into the fitting hole. After the connection, the other side opposite to the one side of the second printed wiring board is inserted into the cut of the connecting member to fix the connecting member to the first printed wiring board.

TECHNICAL FIELD The present invention relates to a printed wiring board combination method.

With the recent rapid development of electronic devices, there is an increasing demand for a high-density mounting structure of a printed wiring board, which is a high density mounting of electronic components such as IC and LSI on the printed wiring board. Therefore, the components mounted on the printed wiring board have been converted from the conventional DIP type IC to a surface mount type such as a flat package type or a chip carrier type. In addition to such a high-density mounting structure of a printed wiring board, the tendency to use a plurality of printed wiring boards in combination has recently increased with the complexity of the device. Therefore, there is a demand for a printed wiring board combination structure that can be easily combined and can be easily assembled and separated during testing and maintenance.

2. Description of the Related Art A conventional printed wiring board combination structure is constructed as shown in FIG. In FIG. 4 (A), four hexagonal interval bolts 14 are sandwiched between the main printed wiring board 10 and the slave printed wiring board 12, and screws 16 are provided from both sides.
It is fixed by. Further, in the conventional example of FIG. 4 (B), four spacers 18 are sandwiched between the main printed wiring board 10 and the slave printed wiring board 12, bolts 20 are inserted into the spacers 18 and fixed by nuts 22. is doing.

Problems to be Solved by the Invention Thus, in the conventional printed wiring board combination structure, the hexagon bolt 14 and the screw 16 are used (FIG. 4 (A)), or the spacer 18, the bolt 20, and the nut 22 are used. Then (FIG. 4 (B)), the two printed wiring boards 10 and 12
Since a large number of parts were required, it was necessary to take great care not to lose the parts when disassembling during testing and maintenance. Further, since the hexagonal spacing bolt 14, the spacer 18, the nut 22, etc. are large in size,
There is a problem that the conductive pattern regions of the printed wiring boards 10 and 12 are narrowed by these components, which is inconvenient for high-density mounting.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a printed wiring board combination method capable of enlarging a pattern area and facilitating assembly and separation during test / maintenance. is there.

Means for Solving the Problems A female side member 24 having a fitting hole 25a is fixed to one side of the first printed wiring board 10 and a cut 32a is formed on the other side opposite to the female side member 24.
The connecting member 32 having the above is temporarily fixed, and the first printed wiring board 10 is attached to the corresponding side of the second printed wiring board 12.
The male member 28 having the fitting protrusion 28a that fits in the fitting hole 25a is fixed. Further, after fitting the fitting protrusion 28a into the fitting hole 25a, the second printed wiring board 12
The other side opposite to the one side of the notch 32 of the connecting member 32
After being inserted into a, the connecting member 32 is fixed to the first printed wiring board 10.

In order to combine the working first printed wiring board 10 and the second printed wiring board 12, first, the fitting protrusion 28a of the male member 28 fixed to the second printed wiring board 12 is formed on the first printed wiring board 10. Fitting hole 2 of female side member 24 fixed to
Fit in 5a. Next, the other side of the second printed wiring board 12 that faces the one side is inserted into the notch 32a of the connecting member 32 that is temporarily fixed to the first printed wiring board 10, and then the connecting member 32 is attached to the first printed wiring board. By fixing to the board 10, the 1st printed wiring board 10 and the 2nd printed wiring board 12 can be easily combined.

Embodiments Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a perspective view of an embodiment of the present invention, and FIG. 2 is a side view of the embodiment. Fitting portions 25 having fitting holes 25a are integrally formed at both ends of the male side member 24, and further, approximately 9
The mounting portion 26 bent at 0 degrees is also integrally formed. The male side member 24 is fixed to one side of the main printed wiring board 10 by screwing the mounting portion 26 to the main printed wiring board 10 with the screw 27. Reference numeral 28 is a female member, and fitting protrusions 28a that fit into the fitting holes 25a of the male member 24 are integrally formed at both ends thereof. The male member 28 is fixed to the secondary printed wiring board 12 with a screw 30.

On the other hand, a pair of connecting members 32 each having a notch 32a on the other side of the main printed wiring board 10 facing the one side are provided with screws 34.
To fix it temporarily. In this case, it is desirable that the holes 33 formed in the main printed wiring board 10 have an elliptical hole shape as shown in FIG. With this oval hole 33,
When the connecting member 32 is temporarily fixed with the screw 34, the circular arc movement of the connecting member 32 as shown by the arrow A in FIG. 2 can be easily allowed.

Then, the sub printed wiring board 12 is replaced with the main printed wiring board 1
In the case of combination with 0, first, the fitting protrusion 28a of the male side member 28 fixed to the slave printed wiring board 12 is inserted into the fitting hole 25a of the female side member 24 fixed to the main printed wiring board 10. Mating. Next, as shown in FIG. 2, the temporarily fixed connecting member 32 is rotated from the broken line position to the solid line position in an arc shape as shown by the arrow A, and the rear end portion (left end portion) of the slave printed wiring board 12 is rotated. The notch 32a of the connecting member 32
Fit inside. Then, the screw 34 is tightened to complete the combination of the main printed wiring board 10 and the sub printed wiring board 12. When the two printed wiring boards 10 and 12 are separated from each other, the main printed wiring board 10 is reversed by the procedure reverse to the above.
The sub printed wiring board 12 and the sub printed wiring board 12 can be easily separated. In this case, the female member 24, the male member 28,
Since it is not necessary to separate the connecting member 32 from the printed boards 10 and 12, loss of these parts can be prevented.

In the above-described embodiment, the female member 24 and the male member 28 are described as being integrated on the left and right of the printed wiring board, but these members are separate members on the left and right sides of the main printed wiring board 10 or the slave. It may be fixed to the printed wiring board 12.

EFFECTS OF THE INVENTION Since the printed wiring board combination structure of the present invention is configured as described above in detail, the printed wiring board can be easily assembled and separated at the time of testing / maintenance, and it is not necessary to disassemble the assembled parts to the end. Therefore, there is an effect that loss of parts can be prevented. Further, since the conductive pattern area of the printed wiring board can be expanded, the component mounting density can be improved.
