Incorrect insertion prevention structure of connector and the connector

A connector assembly which is provided with an incorrect insertion prevention structure which prevents a first connector from being incorrectly inserted into a space formed within a second connector to be fitted to the first connector,

• wherein in the incorrect insertion prevention structure, the first connector includes at least one first magnet located on a surface, at an insertion end to be inserted into the second connector,
• wherein the second connector includes:
• a shutter rotatably and pivotally supported by a rotating shaft to open and close an inlet of the space, and a shutter rotation prevention unit rotatably and pivotally supported by a supporting shaft in parallel to the rotating shaft of the shutter to prevent the shutter from being rotated in an opening direction, and
• wherein the shutter rotation prevention unit includes at least one engaging member facing a rotation end of the shutter in a closed state to prevent the shutter from being moved in the opening direction, and at least one second magnet having a magnetic field which is set to control a rotation of the shutter rotation prevention unit by acting together with a magnetic field of the first magnet;
• and
• wherein the first connector is prevented from insertion into the space of the second connector if the polarity of the first magnet is opposite the polarity of the second magnet, and the first connector is not prevented from insertion into the space of the second connector if the polarity of the first magnet is the same as the polarity of the second magnet.
