  • Patent number: 9093777
    Abstract: Provided is a connector in which a cover is readily closed when ice is induced between a pair of shaft attachment plates by such snowfall. A connector mounted in an electric vehicle and connected to a connector of a charge cable is provided with a housing, a cover rotatably pivoted by the housing and covering an opening of the housing, a latch, and shafts. The cover is provided with a pair of shaft attachment plates and a rib arranged between the pair of shaft attachment plates. The rib extends in a direction perpendicular to a direction of the pair of shaft attachment plates being opposed to each other, and formed such that its tip is peaked. In the connector, even when ice is induced, rotation of the cover in closing direction allows the ice to be broken by the rib so as to readily close the cover.
