JP2572508Y2 - Input / output shared I / O board for parent and child boards - Google Patents

Description

[Detailed description of the invention]

[0001]

The present invention relates to an I / O board composed of a parent board and a child board, which can share input and output by changing the direction of the child board.

[0002]

2. Description of the Related Art Conventionally, I / O boards dedicated to input and output are used, and I / O boards that can share input and output are not used. The idea is to attach one set of input connector and one set of output connector to the parent board, attach the output connector to the input connector in the opposite direction, and rotate the child board by 180 °, so that the child board is attached to the parent board. It is an object of the present invention to provide an input / output shared I / O board that can be connected to an input connector or an output connector.

[0003]

In order to achieve this object, according to the present invention, in an I / O board constituted by a parent board 1 and a child board 2, an input / output connector 3, a control signal Connector 4, input connector 5
A, an input connector 5B, an output connector 6A, and an output connector 6B are attached, the input connectors 5A and 5B are attached at an interval L, the output connectors 6A and 6B are attached at an interval L, and the output connector 6A is attached to the input connector 5A. Are mounted in the opposite direction, the output connector 6B is mounted in the opposite direction with respect to the input connector 5B, and the connectors 7A and 7B are mounted on the slave board 2 at an interval L. When the input connector 5A is connected, the connection connector 7B is connected to the input connector 5B, and a signal is output, the connection connector 7A
A and the output connector 6B are connected, and the connection connector 7B and the output connector 6A are connected.

[0004]

Next, the configuration of the input / output shared I / O board according to the present invention will be described with reference to FIG. 1 in FIG. 1 is a parent board, 2
Is a child board, 3 is an input / output connector, 4 is a control signal connector, 5A and 5B are input connectors attached to the parent board 1, 6A and 6B are output connectors attached to the parent board 1, and 7A and 7B are child boards. A connector attached to 2 and 8 is an IC to be driven.

The parent board 1 has an input / output connector 3, a control signal connector 4, input connectors 5A and 5B, and output connectors 6A and 6B. Input connector 5A
On the other hand, the output connector 6A is attached in the opposite direction, and the output connector 6B is attached in the opposite direction to the input connector 5B. The connectors 7A and 7B are attached to the child board 2.

When inputting a signal, the connector 7A
And the input connector 5A, and the connection connector 7B and the input connector 5B. Thus, the input signal from the input / output connector 3 is transmitted to the drive IC 8 on the slave board 2.
Through the control signal connector 4 as data.

To output a signal, the child board 2 is detached from the parent board 1, the child board 2 is rotated by 180 °, the connector 7A is connected to the output connector 6B, and the connector 7B and the output connector 6A are connected. Connecting. Thus, a signal received as data from the control signal connector 4 is extracted from the input / output connector 3 through the drive IC 8 on the slave board 2.

Next, the connection state between the parent board 1 and the child board 2 will be described with reference to FIG. FIG. 2A is a plan view of the parent board 1, and FIG. The input connectors 5A and 5B are attached to the parent board 1 at intervals L, and the output connectors 6A and 6B are attached to the parent board 1 at intervals L. The connectors 7A and 7B are attached to the child board 2 at intervals L.

Input connectors 5A and 5B, output connector 6
A · 6B and connectors 7A · 7B are spaced L
For example, in the case of an input signal, if the connection connectors 7A and 7B of the child board 2 are erroneously connected to the output connectors 6A and 6B of the parent board 1, the drive IC 8 will be damaged. Therefore, the output connectors 6A and 6B are reversed with respect to the input connectors 5A and 5B. Thereby, the direction of the erroneous insertion prevention key 9 of the input connector 5A and the output connector 6A is reversed, so that erroneous insertion of the child board 2 can be prevented.

[0010]

Next, the configuration of the embodiment of FIG. 1 will be described with reference to FIG. In FIG. 3, 2A to 2C are slave boards, 3A to 3C are input / output connectors, and 4A and 4B are control signal connectors. When the child boards 2A to 2C are placed on the parent board 1 as shown in FIG. 3, the input / output connectors 3A and 3B are used for input, and the input / output connector 3C is used for output. There are eight types of usage depending on the combination of the parent board 1 and the child boards 2A to 2C in FIG.

[0011]

According to the invention, one set of input connector and one set of output connector are attached to the parent board, and the output connector is attached to the input connector with the orientation of the output connector reversed. By rotating, the child board can be connected to the input connector or the output connector of the parent board.
