  • 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.

  • Publication number: 20200321743
    Abstract: A terminal removal jig includes a jig body including a release pin configured to release a terminal from being locked by a lance provided in a connector housing, and an attachment configured to be detachably attached to the jig body and to guide the release pin toward the lance by coming into contact at least a part of the attachment with an inner wall of the connector housing when the release pin is inserted into the connector housing. The attachment is attached to the jig body so as to be movable between a first position in the jig body and a second position located on a tip end side of the jig body relative to the first position, and includes a lock portion configured to lock the attachment to the jig body when the attachment is in the second 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: 8544406
    Abstract: A meter device is disposed on an upper surface of a fuel tank that is disposed between a steering handlebar and a rider's seat. The meter device includes a dial substrate having a scale and a pointer that is rotated by a drive portion and points to the scale corresponding to a measurement output. The pointer includes a ridge that extends in a longitudinal direction and a spine portion having two surfaces that cross each other so as to form the ridge. An angle ?, at which the two surfaces forming the ridge cross each other, is formed into an acute angle, so that a side farther from the ridge as viewed from a side of a rider is not visible.
