リント基板の接続方法。1. A device having an electronic circuit in which a plurality of flexible printed circuit boards are connected by a flexible printed circuit board connector, and the flexible printed circuit board connector of the first flexible printed circuit board which is the flexible printed circuit board connecting portion is mounted. The connecting end portion of the second flexible printed circuit board having the connected connecting end portion and the terminal portion to be inserted into the connector is extended to be formed so as to be drawn out from the opening of the device housing to the outside, and the connecting portion is used for connection work. After the connection is completed, in the connection method in which the connection portion is folded and housed in the housing, the insertion port of the flexible printed circuit board connector and the direction of the insertion end of the connection partner to each flexible printed circuit board extension direction are set. The first frame with the flexible printed circuit board connectors mounted in opposite directions. The flexible printed circuit board is characterized in that the connection end portion of the flexible printed circuit board and the connection end portion of the second flexible printed circuit board having the plug-in terminal portion are overlapped and translated at least in the vicinity of the connection portion, and then plugged in. Connection method.
