  • Patent number: 11721926
    Abstract: A connector includes a housing configured to accommodate a connection terminal, a shutter that is rotatably provided in the housing and is configured to open and close a front opening of the housing, a rotation lever that is rotatably supported to the housing about a rotation axis, and an interlocking rotation mechanism provided between the rotation lever and the shutter and configured to rotate the shutter in accordance with rotation of the rotation lever. A pressing force of the mating connector, whose fitting tip end portion is moved to a position facing the front opening, acts on a lever front end portion of the rotation lever so as to rotate the rotation lever, and thus the shutter is rotated by the interlocking rotation mechanism so as to open the front opening.

  • Publication number: 20230010734
    Abstract: There is a connector including: a first connector; and a second connector that has a cover configured to cover a front surface opening of a housing and a biasing member that biases the cover to a position where a cover portion covers the front surface opening. An opening edge of the front surface opening includes an inclined plane that intersects with a connector fitting direction and that is parallel to a rotation axis of the cover, the inclined plane intersecting at an obtuse angle with a straight line that extends from an opening edge end portion of the front surface opening and that orthogonal to the rotation axis. The connector is designed to rotate the cover to a position where the cover portion does not cover the front surface opening in response to a protruding portion of the first connector pressing a pressed portion of the cover.
