Connector including a rotatble connection member
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 arm that is rotatably supported to the housing about a rotation axis and has an arm portion and a connection engagement portion, and a connection member that is provided so as to be rotatable together with the shutter and includes a first lever portion that is pressed and rotated by a tip end of the connection engagement portion. A pressing force of the mating connector acts on the arm portion so as to rotate the rotation arm, and thus the shutter is rotated together with the connection member rotated by the connection engagement portion 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 arm 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 arm including an arm portion that extends toward a front side of the housing relative to the rotation axis, and a connection engagement portion that extends toward another side portion side of the front opening relative to the rotation axis; and
a connection member that is provided so as to be rotatable together with the shutter and includes a first lever portion that is pressed and rotated by a tip end of the connection engagement portion,
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 arm portion so as to rotate the rotation arm, and thus the shutter is rotated together with the connection member rotated by the connection engagement portion so as to open the front opening.
2. The connector according to claim 1 , wherein the connection member includes a second lever portion that is disposed so that the tip end of the connection engagement portion is located between the first lever portion and the second lever portion and extends outward in a rotation radius direction different from that of the first lever portion, and
wherein the connection engagement portion includes an auxiliary engagement portion configured to press the second lever portion and rotate the connection member by a predetermined rotation angle or more after the tip end of the connection engagement portion presses the first lever portion and rotates the connection member by the predetermined rotation angle.
3. The connector according to claim 1 , wherein the connection member is constantly urged by an elastic member in a direction in which the shutter closes the front opening.
