  • Patent number: 9466906
    Abstract: A connection terminal has a movable contact portion that protrudes so as to be able to be pressed from an outside of a contact hole of a housing, and a first curved portion and a second curved portion that are continuously disposed and form a substantial S-shape. The movable contact portion is provided in a free end portion of the first curved portion. A position controlling projection extends from the movable contact portion. The position controlling projection abuts on an inner circumferential surface of the first curved portion or a region where the first curved portion and the second curved portion are continuously coupled to each other when the movable contact portion is pressed.

  • Patent number: 8678851
    Abstract: A method for manufacturing a metal component includes the steps of forming a resist film on a surface of an electrode plate, making the resist film exposed to light by use of a photomask having a mask pattern, in at least part of a rim of which a fine concavity and convexity are drawn, developing the resist film, to form an opening for molding in the resist film, and epositing an electroforming material by electroforming inside the opening for molding, to mold the material.

  • Patent number: 8556667
    Abstract: A space-saving terminal includes a depth that is short and a floor space that is small. The terminal further includes a fixing part for press-in pressed into and fixed to a base material, a support part projected upward so as to cross with the fixing part for press-in, two extension parts extended downward while meandering from a branch portion on a tip of the support part so as to form a meandering slit, and a movable contact part projected from a tip portion formed by integrating free ends of the extension parts so as to be capable of moving in and out of a contacting hole of the base material. The support part is curved outward in order to avoid contact with the tip portion of the extension part while the tip portion is displaced.

  • Patent number: 8197290
    Abstract: A compact electric connector in which a contact has a high contact pressure and a large displacement amount is provided. An electric connector includes a contact spring and an auxiliary spring. The contact spring includes a support portion that is supported by a housing, a contact portion that is projected from the housing to abut on the-other-end contact, and a plurality of flexing portions that are bent so as to be deformed between the support portion and the contact portion when the contact portion is pushed into the housing. The auxiliary spring includes a flexing auxiliary portion that abuts on the contact spring to exert an elastic force in a direction in which deformation of the flexing portion closest to the support portion is obstructed when the contact portion of the contact spring is pushed into the housing.
