Abstract

PURPOSE:To provide fixing structure of a circuit board which fixes the circuit board with a different circuit board and connects them electrically and its fixing method. CONSTITUTION:As a conductive support column 3 and a screw mechanism are required to mount or fix a circuit board 1 with a circuit board 2, the circuit board 1 is electrically connected to the circuit board 2 when the circuit board 1 is mounted on or fixed with the circuit board 1. Furthermore, both the circuit boards 1 and 2 can be installed to or removed from the conductive support column with ease. Therefore, both the fixing work of the circuit boards and electric connections can be carried out collectively and they can be installed or removed easily and, what is more, effectively.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixing structure and a fixing method for fixing another circuit board by an easily attachable / detachable mechanism while making electrical connection on the circuit board.

[0002]

2. Description of the Related Art FIG. 3 shows, for example, Shoukai 61-130742.
It is a front view which shows the fixing structure of the conventional circuit board shown by the publication. In the figure, 1 and 2 are two circuit boards, 3 is a plurality of electroconductive pillars, 4 and 5 are on the circuit boards 1 and 2. Circuit components that are mounted on.

Next, a method of fixing the circuit board will be described. Both the circuit board 1 and the circuit board 2 are circuit components 4, 5
Are fixed by the conductive columns 3 with their mounting surfaces facing each other, and the conductive columns 3 are electrically connected to the wiring on the circuit boards 1 and 2 by soldering on the soldering surfaces of the circuit boards 1 and 2. And the circuit board 1 and the circuit board 2 are fixed by the conductive columns 3.

[0004]

Since the conventional circuit board fixing structure is constructed as described above, when the circuit boards 1 and 2 once fixed are repaired, the circuit boards 1 and 2 become electrically conductive. When the pillar 3 needs to be removed, for example, when the conductive pillar 3 is fixed to the circuit boards 1 and 2 by soldering or the like, the solder must be removed.
After the repair is completed, the circuit boards 1 and 2 cannot be fixed unless the circuit boards 1 and 2 are soldered again to fix the circuit boards 1 and 2. Therefore, the circuit boards 1 and 2 cannot be easily attached and detached. Further, there is a problem that the life of the circuit boards 1 and 2 is shortened due to heat when soldering and removing the solder.

The present invention has been made in order to solve the above-mentioned problems, and a circuit board once fixed can be easily attached and detached so that the circuit board can be easily repaired and the circuit board can be added. An object is to obtain a fixing structure and a fixing method for a circuit board that can be mounted.

[0006]

SUMMARY OF THE INVENTION A circuit board fixing structure according to the present invention is a mechanism for fixing a conductive pillar to a circuit board by electrically connecting the conductive pillar and wiring on the circuit board and by making the conductive material conductive. The column is fixed to the circuit board by a mechanism that can be easily attached to and detached from the circuit board.

[0007]

In the circuit board fixing structure according to the present invention, since the conductive support and the wiring on the circuit board are electrically connected and fixed by the detachable mounting mechanism, the conductive support and the circuit board can be easily attached and detached. In addition, it is possible to achieve electrical continuity between the circuit boards.

EXAMPLES Example 1. An embodiment of the present invention will be described below with reference to FIG.
Will be described. In the figure, 6 is a screw mechanism for fixing the conductive support 3 to the circuit boards 1 and 2, respectively. The other parts are the same as those of the above-mentioned conventional device, and therefore, the same reference numerals are given and the description thereof is omitted.

On the soldering surface of the circuit board 1, there are wirings for making electrical connection with the conductive columns 3, and the wirings are not subjected to an insulation treatment and have continuity on the surface. On the component mounting surface of the circuit board 2, there are wirings for electrically connecting with the conductive columns 3 at positions corresponding to the positions of the wirings for electrically connecting with the conductive columns 3 of the circuit board 1. The wiring is not insulated and has continuity on the surface. When the conductive support columns 3 are fixed to the circuit boards 1 and 2 by the screw mechanism 6, the circuit boards 1 and 2 and the conductive support columns 3 are tightened by the screw mechanism 6.
, And the circuit boards 1 and 2 are fixed by the conductive columns 3 and the screw mechanism 6.

In FIG. 1, when repairing the circuit board 1, for example, the circuit board 1 can be removed by removing the screw mechanism 6 fixing the circuit board 1 and the conductive support 3. To install the circuit board 1 that has been repaired,
The circuit board 1 is fixed by the screw mechanism 6 to the conductive columns 3 which are fixed to the circuit board 2 by the screw mechanism 6.

Embodiment 2. Next, another embodiment of the present invention will be described with reference to FIG. In the figure, the circuit board 2 is different from that of the first embodiment in that the circuit board 2 is previously incorporated in or mounted on a device or its equivalent. The circuit board 1 is mounted or fixed on the circuit board 2. For example, the circuit board 1 can be additionally mounted later as a circuit board having an auxiliary function of the circuit board 2. The wiring positions on the boards of the circuit boards 1 and 2 for making electrical connection with the conductive columns 3 are the same as the positions described in the first embodiment.
The wiring is not subjected to insulation treatment and has continuity on the surface.

In the case where the circuit board 1 is additionally mounted, an example is shown in which the conductive columns 3 are first fixed to the circuit board 1 by the screw mechanism 6 and then the conductive columns 3 are fixed to the circuit board 2 by the screw mechanism 6. Although shown, it is also possible to first fix the conductive support pillar 3 to the circuit board 2 by the screw mechanism 6 and then fix the circuit board 1 to the conductive support pillar 3 by the screw mechanism 6.

The distance between the circuit board 1 and the circuit board 2 is adjusted by changing the length of the conductive support 3 in the above-described first and second embodiments, and the circuit board 1 is replaced with the circuit board 2.
It is also possible to mount or fix it on.

[0014]

As described above, according to the present invention, since the conductive columns and the detachable mounting mechanism are used for mounting or fixing the circuit board on another circuit board, the electrical connection between the circuit boards is achieved. It has an effect that it can be connected and can be easily attached and detached.
