Description

  The present invention relates to a relay board mounting structure.

  Conventionally, what is shown in Patent Document 1 is known as a relay board for electrically connecting devices.

  This relay board includes a connector for connecting a motherboard and a connector for connecting a circuit board, and makes the motherboard and the circuit board conductive.

  By the way, the mother board and the circuit board connected by the relay board are both arranged inside the equipment casing, and do not connect the equipment inside the equipment casing to the equipment outside the equipment casing.

  Here, in order to connect the device inside the device housing and the device outside the device housing using the technique of Patent Document 1, it is conceivable to provide a through hole for passing a connector on the device side outside the device housing. However, if this is done, the inside and outside of the device casing may be communicated through the through-holes and various problems may occur, and in order to solve this, a member for closing the through-holes is required separately.

  Further, in order to connect the device inside the device housing and the device outside the device housing, a relay connector is provided on the device housing without using the relay board, and an electric wire connected to the device inside the device housing by the relay connector It is also conceivable to relay an electric wire connected to a device outside the device casing. However, this increases the total number of relay connectors and causes an increase in cost. In order to solve this, for example, wires of the same potential among wires connected to the device in the device casing are connected with a capsule terminal or the like, and the same potential of the wires connected to the device outside the device housing is connected. Although it is conceivable to connect the electric wires with capsule terminals or the like, in this case, a complicated operation is required.
