  • Publication number: 20220013958
    Abstract: A connector includes a housing, a holder, and a short-circuiting terminal. The holder is non-movable to a formal locking position when terminals, which are short-circuiting targets, are not inserted into a terminal receiving chamber. The holder is movable to the formal locking position when the terminals, which are short-circuiting targets, are inserted into a sufficient insertion position of the terminal receiving chamber. A contact member of the short-circuiting terminal is in contact with the terminals, which are short-circuiting targets, and the terminals, which are short-circuiting targets, are short-circuited when the terminals, which are short-circuiting terminals, are inserted into the sufficient insertion position and the holder is moved to the formal locking position.

  • Patent number: 11189978
    Abstract: A connector includes: a housing; and a short-circuit terminal. A deformable portion is configured to deform in a direction of moving away from the terminal during housing of the terminal and to deform in a direction of moving closer to the terminal when the housing of the terminal is finished. The short-circuit terminal has, as different portions, a contact point portion to contact with the two or more terminals and a push target portion to contact with the deformable portion. The short-circuit terminal is configured to reduce its pressure of contact toward the terminal at the contact point portion, during the housing of the terminal, due to a movement of the push target portion along with the deformable portion.

  • Publication number: 20200373711
    Abstract: A connector includes: a housing; and a detector detecting whether a terminal is received at a regular position. The locking portion has an abutment part to lock the terminal, and an interference part interfering with the detector to prevent the detector from being assembled to the housing. The abutment part is displaced to lock the terminal at the regular position when the terminal is at the regular position, and to leave the terminal when the terminal is not at the regular position. The interference part moves along with the abutment part to a position not to interfere with the detector when the terminal is at the regular position, and to be displaced to a position to interfere with the detector when terminal is not at the regular position.

  • Patent number: 10566732
    Abstract: There is provided a waterproof connector structure which includes a pair of connector housings. An opening end portion of a cylindrical body of one connector housing is inserted into an opening end portion of a cylindrical body of another connector housing at the time of fitting. One cylindrical body has a projection part which is provided to protrude outward in a radial direction from the opening end portion thereof entirely in a circumferential direction. The projection part is provided on a front side in a fitting direction from an opening part of a terminal receiving chamber surrounded by the one cylindrical body.

  • Patent number: 10559924
    Abstract: The connector includes an inner housing, an outer housing, a locking mechanism for locking, a spring member that pushes back the inner housing during half fitting, and a pushback regulating position that regulates a pushback position. The pushback regulating portion includes a claw portion, a stepped portion against which the claw portion abuts, and a sliding load portion that makes a sliding friction force between the inner housing and the outer housing at a predetermined timing before abutting to be larger than the sliding friction force before the predetermined timing.

  • Patent number: 10283902
    Abstract: In a waterproof structure for a connector, in order to prevent that water is infiltrated into openings of cavities accommodating terminals, a pair of housings include resin annular members which protrude in a fitting direction to surround the openings. One annular member has a protrusion part which is formed on a way between a tip and a root thereof over an entire circumference. The protrusion part is formed to have a top part which presses an inner circumferential surface or an outer circumferential surface of the counterpart annular member at a time of fitting the pair of housings.
