  • Publication number: 20210367371
    Abstract: A connector includes a female housing and a male housing. An arm portion of the female housing engages with an engagement projection of the male housing. In a state where the engagement projection is fitted to an opening of the arm portion, a gap for insertion of a jig exists in the opening at a lateral side of the engagement projection. A groove-shaped release operation portion is formed on the male housing at a lateral side of the engagement projection. An inclined surface is formed at a rear end of the release operation portion, and a wall portion is formed on a rear side of the inclined surface. The arm portion engaged with the engagement projection can be released with a simple operation including inserting the jig into the release operation portion from the gap in the opening and pushing the jig in the same direction as the insertion direction.

  • Publication number: 20200325941
    Abstract: A rotary connector includes: a first housing; a second housing; a bayonet ring including a locked portion to be locked to a locking portion of the first housing, which forms a bonded state by rotating by a predetermined angle in a ready state, so that its rotation is prevented; and a connector position assurance that is prevented from moving from a first position in the ready state, and in the bonded state, that is moveable to a second position and maintains a state in which the locked portion is locked to the locking portion.

  • Patent number: 9780489
    Abstract: A lock structure of a connector includes a lock arm and a lock release arm which are provided in one connector housing of a pair of connector housings which are fitted into each other. The lock arm is engaged with a lock engagement part of the other connector housing to lock a fitting state between the connector housings when fitting between the connector housings is completed. The lock release arm is formed integrally with the lock arm and can deflect the lock arm in a lock release direction. The lock release arm is provided above the lock arm.

  • Publication number: 20170264050
    Abstract: A connector includes a female housing, an engagement detection member, and a cover member. The female housing is provided with a terminal connected to a counterpart terminal of a counterpart connector and is capable of being engaged with the counterpart connector. The engagement detection member is assembled with the female housing in a movable manner from an initial position to an engagement assurance position in a state where the counterpart connector and the female housing are completely engaged with each other. The cover member is assembled with the engagement detection member through a locking unit locked with the engagement detection member. The locking unit is provided inside an outer shape line of the engagement detection member when viewed in a direction of relative movement between the female housing and the engagement detection member.

  • Patent number: 9742115
    Abstract: A connector includes a first housing including a first lock part, a second housing including a second lock part that can be locked to the first lock part, and a fitting detection member that can move from an initial position to a fitting assured position with the second lock part locked to the first lock part and includes a third lock part that can ride over the first lock part and the second lock part in succession along with the movement from the initial position to the fitting assured position to be locked to the second lock part at the fitting assured position. The first lock part includes a drawing slope surface inclining from a protruding tip toward a first lock face and a protrusion protruding from the drawing slope surface. The second lock part includes a notch that can house the protrusion.

  • Patent number: 9461400
    Abstract: An electric wire cover includes: a first electric wire cover including a wire arrangement space like a groove opened on one side, and attached to a wire lead-out end of a connector housing; and a second electric wire cover formed integrally with the first electric wire cover through a hinge portion, and covering the wire arrangement space. A guide groove is provided in one of the first and second electric wire covers, and extends in a direction perpendicular to a rotation axis of the hinge portion. A rotation restriction rib is provided in the other electric wire cover and extends in the direction perpendicular to the rotation axis. The rotation restriction rib slides in the guide groove during rotating operation by the hinge portion so as to restrict rocking of the electric wire covers relative to each other.

  • Patent number: 9142919
    Abstract: An incomplete fitting prevention connector includes a first connector, a second connector that is fitted to the first connector, and a connector position assurance lock that is slidably mounted to an outer side of the second connector. The first connector includes a male beak, a short spring and a terminal. The second connector includes a female lock passing over the male beak and a short-circuit removal plate part inserted between the short spring and the terminal. A draw-in slanted surface is formed at a leading end of the male beak, a restoring force for returning the female lock to its original position serves as a driving force for fitting the connector when the female lock reaches the draw-in slanted surface, and the insertion force of the short-circuit removal plate part applied between the short spring and the terminal is reduced.
