  • Patent number: 11239596
    Abstract: A connector includes: a plurality of terminals; a housing having a tubular outer wall part, a holding part having a plurality of terminal housing chambers, lances positioned radially outside the respective terminal housing chambers, and a locking part; and a detection member having a tubular fitting part to be fit to the holding part and an engaging part. The lances, when the respective terminals are inserted into a regular position in the respective terminal housing chambers, enter the inside of the fitting part when the fitting part is fit to the holding part and, when the respective terminal are not inserted into the regular position, are pressed by the respective terminals to become deformed radially outward and to lock the fitting part at a first position, the first position being short of a position at which the engaging part is engaged with the locking part.

  • 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.

  • Patent number: 11189952
    Abstract: A connector includes: a housing having terminal housing chambers, one passage part, and lances; terminals inserted into the respective terminal housing chambers and locked by the respective lances at a regular position; and a detection member inserted into the passage part to detect whether the terminals are inserted to the regular position. The passage part is adjacent to each of the terminal housing chambers. The lances are provided at a boundary between the respective terminal housing chambers and the passage part. The lances, when the respective terminals are not inserted to the regular position, are pressed by the respective terminals to lock the detection member at a first position. The lances, when the respective terminals are inserted to the regular position, allow the detection member to be inserted into a more inner position than the first position.

  • 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.
