    摘要： An evaluation method is a method for evaluating a charging connector in coolability by connecting an evaluation jig to the charging connector, the charging connector including a pair of male terminals coolable with a coolant, the evaluation jig including a pair of female terminals, the pair of female terminals being connected to the pair of male terminals in evaluating the charging connector in coolability. The method comprises: connecting the pair of female terminals to the pair of male terminals; adjusting a connection state between the male terminal and the female terminal such that contact resistance between the terminals is 0.06 mΩ or more and 0.15 mΩ or less; and after the adjusting, evaluating the coolability depending on whether the male and female terminals have a temperature of 90° C. or lower when a charging current of 400 A is supplied to the terminals for 30 minutes.

    摘要： The evaluation jig comprises a pair of female terminals connectable to a pair of male terminals of a charging connector and an adjustment member capable of adjusting contact resistance of the female terminal and the male terminal. The female terminal is reducible in diameter. The adjustment member includes an annular band attached to an outer peripheral surface of the female terminal and formed in an annulus surrounding the female terminal, a metal band attached to an outer peripheral surface of the annular band and capable of applying external force to the female terminal to reduce the female terminal in diameter, and an adjustment unit capable of adjusting the external force applied by the metal band to the female terminal. The annular band is made of an electrically and thermally insulating material.

    摘要： An evaluation method is for evaluating a charging connector in coolability by connecting an evaluation jig to the charging connector, the charging connector including a pair of male terminals and a bottom wall, the evaluation jig including a pair of female terminals, the pair of female terminals being connected to the pair of male terminals in evaluating the charging connector in coolability. The method comprises: connecting the pair of female terminals to the pair of male terminals; and adjusting a connection state of the terminals so that contact resistance between the terminals falls within a prescribed range. In the step of adjusting, a resistance between a point of 4.5 mm of the male terminal from a surface of the bottom wall and a point of 43 mm of the female terminal from the surface of the bottom wall is measured as the contact resistance.

    摘要： A female terminal connectable to a male terminal is provided. At least one of the male terminal and the female terminal is coolable by a coolant. The female terminal includes a female terminal body electrically connectable to the male terminal, and a heat transfer member that transfers cold of the coolant. The female terminal body includes a space forming portion forming a receiving space that receives the male terminal, and a contact portion protruding from the space forming portion and coming into electrical contact with the male terminal. The heat transfer member is electrically insulating and disposed in the receiving space, and comes into thermal contact with the male terminal and the space forming portion when the male terminal is inserted in the receiving space.

    摘要： An evaluation jig comprises a female terminal connectable to a male terminal of a charging connector. The female terminal includes a plurality of contact pieces and a support portion. Each contact piece has a flexible piece, and a contact portion protruding toward the center axis from an inner surface of the flexible piece. The flexible piece forms a portion of a cylinder having the center axis. The flexible piece has a length equal to or larger than twice an outer diameter of the cylinder in a direction parallel to the center axis. The flexible piece is elastically deformable so that the flexible piece has a distal end portion to be displaceable in a radial direction of the cylinder relative to a proximal end portion of the flexible piece. The contact portion has a shape curved so as to protrude inward in the radial direction.
