  • Patent number: 9281594
    Abstract: A connector comprising a first connector provided with first terminals each of which has a movable portion formed so that a dimension in its width direction is larger than a dimension in its thickness direction to be elastically deformed in a fore-and-aft direction (Y direction) of the connector, and a second connector provided with second terminals each of which has a movable portion formed so that a dimension in its thickness direction is larger than a dimension in its width direction to be elastically deformed in a width direction (X direction) of the connector. As compared with a terminal formed so as to be sufficiently elastically deformable in both of the fore-and-aft direction and the width direction of the connector, it is possible to increase a cross-sectional area of each of the movable portions, so that a permissible value of current of each of the terminals can be increased.

  • Patent number: 9178326
    Abstract: The movable portion of the first terminal of the first connector is formed to be larger in the width direction than in the thickness direction, so as to be elastically deformed in the front-back direction of the connector, and the movable portion of the second terminal of the second connector is formed to be larger in the thickness direction than in the width direction, so as to be elastically deformed in the width direction of the connector. Therefore, the movable portions can be formed with an increased cross-sectional area, thereby enabling the allowable current of the terminals to be increased, unlike a configuration in which the movable portion is elastically deformable to a sufficient extent both in the front-back direction and in the width direction of the connector.

  • Patent number: 9088113
    Abstract: A second elastic portion includes a bent section connected via the proximal end portion to a first fixing portion formed so as to circumvent along a shape of a distal end portion and a part of a lateral face of a projecting portion of a first movable housing.

  • Patent number: 8480434
    Abstract: An electrical connection terminal arranged such that when the amount of displacement of one of a first contact portion and a second contact portion increases, a decrease in the contact pressure of the other contact portion is effectively suppressed, and a connector in which the electrical connection terminal is used. Between first and second elastic pieces and a fixed piece, a third elastic piece is provided such that when one of a first contact portion and a second contact portion is displaced in the direction of contact with a mating terminal, the amount of displacement of the other contact portion in the direction of contact with the mating terminal becomes smaller than the amount of displacement of the other contact portion in the insertion and removal direction of the mating terminal. Connection reliability by two-point contact may be improved.
