Abstract: The probe pin includes a plunger formed of a sheet metal, and a coil spring unit formed of a metal wire and configured to hold the plunger thereon. In a developed state, the plunger includes first and second portions each of which has an upper contact strip, a wide portion, and a lower contact strip, and which are connected to each other via the wide portions formed in the first and second portions. The plunger is formed in a united manner by folding together the first and second portions along a boundary of the wide portions formed therein to thereby bring at least the wide portions into tight contact with each other.

Abstract: A ground contact plate in a contact unit includes fixing pieces provided at predetermined equal intervals in a longitudinal direction. The fixing pieces are respectively fitted in opposed slits in ground contact terminals via a transmission blade.

Abstract: The contact head includes a head base, and at least two elastic contact pieces located on an upper end portion of the head base and configured to electrically contact a contact target object. A dent having a circular horizontal cross-sectional shape is formed at a central portion surrounded by the at least two elastic contact pieces. Additionally, each of the elastic contact pieces is formed with a tip end serving as a free end of the elastic contact piece located on a circumference of at least one virtual circle which is a circle concentric with an inscribed circle inscribed in a horizontal cross-sectional shape of the head base and which has a diameter being the same as or smaller than a diameter of the inscribed circle. Moreover, the contact piece is formed to be elastically deformable in a vertical direction by being formed to extend spirally.

Abstract: A card connector with an ejection mechanism is described. The card connector may include a base member, a cover member, a card accommodating space, and contact lines, which are electrically connected to a card placed into the card accommodating space. The card connector may also include an ejection lever, a spring, which pushes the ejection lever to the card accommodating space, and a pair of guide walls, which lead the ejection lever in a card insertion/withdrawal direction. The card connector may further include an ejection mechanism for pulling the IC card out of the card accommodating space. The ejection lever may include an arm portion, which comes in contact with a front end portion of the card, a spring mounting portion, a slide portion, which is led to a pair of the guide walls, and a pull portion, which extends outside the base member.
