Connector with an interlocking rotation mechanism
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.
1. A connector comprising:
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 to which a fitting tip end portion of a mating connector is to be fitted;
a rotation lever that is disposed on one side portion side of the front opening and is rotatably supported to the housing about a rotation axis intersecting a connector fitting direction of the mating connector, the rotation lever having a lever front end portion that extends toward a front side of the housing relative to the 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, wherein
a pressing force of the mating connector, whose fitting tip end portion is moved to a position facing the front opening, acts on the lever front end portion 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.
2. The connector according to claim 1 , wherein the interlocking rotation mechanism includes a speed increasing mechanism configured to increase a speed of the rotation of the rotation lever to rotate the shutter.
3. The connector according to claim 1 , wherein
the interlocking rotation mechanism includes a first link and a second link which is rotatably connected to the first link, and
an end portion of the first link is pivotally supported by a lever rear end portion of the rotation lever extending toward a rear side of the housing relative to the rotation axis and an end portion of the second link is pivotally supported by a swinging portion of the shutter.
4. The connector according to claim 1 , wherein the interlocking rotation mechanism includes a first gear portion that rotates together with the rotation lever and a second gear portion that meshes with the first gear portion and rotates together with the shutter.
5. The connector according to claim 1 , wherein
the rotation lever is configured such that a longitudinal direction side portion of the lever front end portion is parallel to the connector fitting direction in a case that the fitting tip end portion is moved to the position facing the front opening, and
the longitudinal direction side portion is engaged with a fitting guide groove formed along the connector fitting direction in a housing of the mating connector that faces the lever front end portion to guide the housing of the mating connector into the front opening of the housing of the connector.
