It has a connector which is electrically connected by fitting the mating direction to the front, the mating release direction to the rear, and mating with the mating connector,
In the connector, a terminal housing chamber penetrating in the front-rear direction is inserted in a plurality of connector housings formed in a plane orthogonal to the front-rear direction, and the terminal housing chambers are inserted forward from the rear to the front restricting position And a plurality of terminals that are retained and locked backward by locking means provided in each of the terminal accommodation chambers, and a longitudinal direction from the side of the connector housing toward the inside of the connector housing When inserted in the orthogonal direction and in the temporary locking position, the insertion and removal of the terminal with respect to the terminal storage chamber is permitted, while the terminal is inserted into the terminal storage chamber to the restricted position and the locking means And a retainer for double locking the terminal with the locking means by being moved from the temporary locking position to the full locking position in the locking state.
The retainer is formed with a recess for detection of reverse fitting opened forward to prevent fitting in a direction opposite to the normal direction with respect to the connector on the other side, and the connector on the other side The connector is inserted into the recess for reverse fitting detection when the mating connector is fitted to the connector in the normal direction with the retainer in the main locking position. When the connector and the mating connector are allowed to be fitted, while the mating connector is fitted to the connector in the opposite direction to the normal direction, interference is caused to the interference wall portion formed on the connector. By doing this, a convex portion for reverse fitting detection is formed which prevents the fitting of the connector and the mating connector.
