Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of supporting a plurality of printed circuit boards in parallel with each other by a control device or the like.

[0002]

2. Description of the Related Art Conventionally, when a plurality of printed boards (hereinafter referred to as "boards") are supported in parallel and the printed wirings of adjacent boards are connected to each other, for example, it is constructed as shown in FIG. That is, reference numeral 1 is a substrate having a printed wiring 11 on one surface. Reference numeral 2 denotes a substrate which is adjacent to and parallel to the substrate 1, and has a printed wiring 21 on one surface. Reference numeral 3 denotes a male connector, which is attached to the other surface of the board 1, and the connection pins 32 projecting from the board mounting surface 31 are passed through the connection holes 12 of the board 1 so as to project to one surface of the board 1 and The projecting connection pin 32 and the printed wiring 11 are soldered to fix the board 1 and the male connector 3 to each other.
Reference numeral 4 denotes a female connector, which is connected to the male connector 3 to connect the printed wirings of the two boards. As with the male connector 3, the female connector 4 is provided on the other surface of the board 2.
The board mounting surface 41 of is fixed. When connecting the board 1 and the board 2, the male side connector 3 and the female side connector 4 are butted against each other, and the connection pins 32 protruding to the connector mounting surface 33 of the male side connector 3 are attached to the connector mounting surface of the female side connector 4. The connection hole 42 opened in 43 is fitted. In this state, hollow spacers 5 are provided between the substrates 1 and 2 at a plurality of locations.
Through the mounting holes 13 in which the screws 6 are formed in the substrates 1 and 2 and through the spacer 2 and the mounting holes 22, the nut 7 is screwed into the screws 6, and the substrates 1 and 2 are spaced apart from each other to form the screws 6 It is fixed at both ends of.

[0003]

However, in the prior art, the connection between the male side connector 3 and the female side connector 4 is made by connecting the connection pin 32 protruding toward the connector side of the male side connector 3 to the connection hole of the female side connector 4. Although the male side connector 3 and the female side connector 4 are indirectly supported via the boards 1 and 2 fixed to both ends of the elongated screw 6, vibration and external force are not generated. When added, the connection pin 32 on the connector side
There is a drawback that the electric connection becomes unstable due to loose fitting between the connection hole 42 and the connection hole 42. An object of the present invention is to provide a method of supporting a printed circuit board that can maintain stable electrical connection.

[0004]

In order to solve the above problems, the present invention is directed to a plurality of printed circuit boards arranged in parallel with each other and spaced apart from each other, and a male connector fixed to one of the adjacent printed circuit boards. A printed circuit board having a female connector fixed to the other adjacent printed circuit board, connecting the male connector and the female connector, and fixing the adjacent printed circuit boards with a screw via a spacer. In the above supporting method, the connectors of the male side connector and the female side connector are directly fixed by detachable fixing means.

[0005]

By the above means, the male side connector and the female side connector are directly fixed by a detachable fixing means such as a screw. Therefore, regardless of the structure for fixing the adjacent boards, the male side connector and the female side connector are A stable connection state can be maintained with the female connector.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a side sectional view showing an embodiment of the present invention. Elements common to those of the conventional example described with reference to FIG. 2 are designated by the same reference numerals, and description thereof will be omitted. In the figure,
Reference numeral 34 is a mounting hole that opens near both ends of the board mounting surface 31 and penetrates the male side connector 3. 44 is a screw hole opened in the vicinity of both ends of the connector mounting surface 43,
The screw 60 inserted in the mounting hole 34 is screwed. When supporting the board 1 and the board 2 with each other, first, the male side connector 3 is fixed to the board 1 and the female side connector 4 is fixed to the board 2 in the same manner as in the prior art. Next, male connector 3
And the female connector 4 are abutted against each other, and the connection pin 32 protruding toward the connector side of the male connector 3 is fitted into the connection hole 42 of the female connector 4 to connect the substrate 1 and the substrate 2. In this state, the screw 60 is passed through the mounting hole 13 of the board 1 into the mounting hole 34 of the male side connector 3 and is screwed into the screw hole 44 of the female side connector 4, so that the male side connector 3 and the female side connector 4 are connected.
Is fixed. The substrate 1 and the substrate 2 at other locations are fixed to each other by sandwiching the hollow spacer 5 and fixing the substrate 1 and the substrate 2 with the screw 6 as in the conventional method. Therefore, since the male side connector 3 and the female side connector 4 are directly fixed by the screw 60,
Regardless of the structure for fixing the substrate 1 and the substrate 2, the male side connector 3 and the female side connector 4 can maintain a stable connection state. In the above embodiment, an example in which the male side connector and the female side connector are fixed by screws has been described, but the means for fixing them is not limited to screws, and any removable fixing means such as a clamp may be used. Good.

[0007]

As described above, according to the present invention, the male side connector and the female side connector are directly fixed by screws or the like regardless of the structure for fixing the adjacent substrates.
Even if vibration or external force is applied, the fitting between the connection pin of the connector and the connection hole does not loosen, stable electrical connection can be maintained, and the reliability of the device incorporating the printed circuit board is improved. is there.
