Abstract: A socket contact terminal for electrical connection between a connection portion formed of a metal conductor on a printed circuit board and a connection terminal of an IC package. The contact terminal comprises a metal terminal composed of a main columnar portion and arm portions on both sides and having an angular U shape and an elastomeric member attached to the metal terminal. A metal surface is exposed from the outer surface of each arm portion. The elastomeric member is firmly held between the arm portions of the metal terminal and exhibits a repulsive force when the arm portions are pressed in the direction that the arm portions approach each other.

Abstract: A socket includes an insulating elastomeric sheet having a penetration hole, metal circuits formed on at least one of the front and rear surfaces of the elastomeric sheet, and a through-hole having a metal film formed on an inner wall of the penetration hole. The metal circuit on the front surface of the elastomeric sheet is electrically connected to the metal circuit on the rear surface of the elastomeric sheet via the through-hole. With such a configuration of the socket, it is possible to provide a socket contact terminal and a semiconductor device having the same, which is suitable for low-resistance, large-current, and high-speed configurations.

Abstract: A connector is provided that includes: a molded base part having a substrate and elastomers arranged on both sides of the substrate; a plurality of through holes in the molded base part, which pass through the molded base part in a stacked direction of the substrate and the elastomers, and are arranged in parallel at predetermined spacing; and L-shaped contacts arranged via the through holes from one surface side of the molded base part to another surface side, wherein: the elastomers incorporate a plurality of first protruding parts whose top faces are inclined, and second protruding parts that protrude from top faces of the first protruding parts in a dome shape; said contact has dome shaped convex parts whose insides are hollow, and said convex parts are formed at two ends of the contact, and the convex parts are arranged such that they cover the respective second protruding parts. Also provided is an electronic component provided with this connector.

Abstract: An aspect of the present invention inheres in an IC socket includes a plate-like socket base body which includes through hole forming portions having a plurality of contact housing holes formed so as to penetrate the plate-like socket base in a front-to-back direction, and having through holes formed around the respective contact housing holes so as to penetrate the plate-like socket base in the front-to-back direction, and a plated layer formed continuously on an inner wall of the through hole, on the front and back surfaces of the through hole forming portion, and on a surface of the contact piece.
