  • Patent number: 11862890
    Abstract: The present disclosure provides a connection terminal and a connector capable of suppressing an increase in manufacturing cost. A vehicle-side terminal 50 includes a terminal connecting portion 51 to be electrically connected to a charger-side terminal, a wire connecting portion 55 to be electrically connected to a wire, and an intermediate portion 56 provided between the terminal connecting portion 51 and the wire connecting portion 55. The terminal connecting portion 51 has a hollow cylindrical shape. The terminal connecting portion 51 includes a first slit 52X, 53X extending over an entire length in an axial direction of the terminal connecting portion 51. The intermediate portion 56 has a rectangular tube shape. The intermediate portion 56 includes a second slit 56X extending over an entire length in an axial direction of the intermediate portion 56.

  • Patent number: 9787012
    Abstract: It is aimed to provide a terminal fitting (1) in which thick plating films can be formed on necessary parts without requiring particularly complicated plating. The terminal fitting (10) includes a tubular connecting portion (11) into which a mating male terminal (60) is insertable. The connecting portion (11) includes a plurality of resilient pieces (14) circumferentially divided via expanding slots (13) extending from a tip. Thick film portions (22) with a thicker plating film than in other parts are provided on inner surfaces of the plurality of resilient pieces (14) and contact areas (17) capable of contacting the male terminal (60) are provided on these thick film portions (22). The thick film portions (22) and the contact areas (17) are arranged continuously in a circumferential direction except at the positions of the expanding slots (13) on an inner surface of the connecting portion (11) near a tip.

  • Publication number: 20170222339
    Abstract: A ground terminal fitting includes a bolt fastening portion (11) to be bolted to a ground part (40) and a wire connecting portion (12) to be connected to an end part of a wire (30). The bolt fastening portion (11) and a bottom plate portion (18) of the wire connecting portion (12) are arranged flush with each other. A protrusion (21) projecting toward the ground part (40) is provided on a part of the bolt fastening portion (11) around a bolt insertion hole (14) through which a bolt (41) is to be inserted. Since a linking portion (13) lining the bolt fastening portion (11) and the wire connecting portion (12) needs not be formed into a bent shape according to this configuration, a stress concentration on the linking portion (13) can be alleviated.
