Abstract

PURPOSE:To perform connection without positioning, and to diminish the requirement for accuracy in mounting a substrate by pivotally supporting a first connection side connector part, so as to rotate freely, to a first substrate side connector part. CONSTITUTION:A connector for the connection of a wiring substrate is formed out of a first substrate side connector part 2 to be mounted on one wiring substrate 1, and a connection side connector part 3 to be mounted so as to rotate freely, with its one side pivotally supported by the first substrate side connector part 2, and a second substrate side connector part 5 to be mounted on the other wiring substrate 4. By plugging the other side of the connection side connector part 3 in the second substrate side connector part 5, the substrates 1 and 4 are electrically connected together. Since the one side of the connection side connector part 3 can be retracted by rotating the other, the connection and the separation of the connectors can be easily carried out. A slight dislocation can be compensated due to the structure of the connector. Accuracy for positioning for mounting of the wiring substrate can not be required so much thereby.

〔Effect of the invention〕

As explained above, according to the present invention, by rotating one side of the connection side connector part 3, the other can be inserted or removed, so that it is possible to connect it after positioning it with respect to the pin assembly as in the conventional case. Connecting and disconnecting the connector becomes easy without any hassle. Therefore, there is no problem of a connecting pin bending and accidentally contacting an adjacent connecting pin during connection.

Furthermore, since the structure of the connector itself can absorb some misalignment, the mounting of the wiring board does not require as much positional accuracy as compared to conventional connectors, and contact failures do not occur during insertion.

Further, since one wiring board can be removed from the casing or the like and held in a rotated state while the wiring boards are connected, work efficiency is improved during operation tests and repairs of the board.
