Abstract: Provided are a contact pin and a socket for inspection that can improve electrical performance or thermal performance. An embodiment includes: an electric conductive electrical contact extending from the base end to the tip and having an elastic deformation part elastically expandable and compressible in the extending direction formed between the base end and the tip; an electric conductive thermal contact extending from the base end to the tip and having an elastic deformation part elastically expandable and compressible in the extending direction formed between the base end and the tip; and an electrically conductive casing that bundles the electrical contact and the thermal contact laterally stacked adjacent to each other, and the casing is in contact with the electrical contact and the thermal contact so as to form a path bypassing the elastic deformation part.

An embodiment includes: an electrically conductive electrical contact extending from a base end to a tip and having an elastic deformation part elastically expandable and compressible in the extending direction formed between the base end and the tip; and an electrically conductive thermal contact extending from a base end to a tip and having an elastic deformation part elastically expandable and compressible in the extending direction formed between the base end and the tip, and the electrical contact and the thermal contact are laterally stacked adjacent to each other and are movable independently of each other.

Abstract: An IC socket (2) includes a first contact terminal (15a) that contacts a gull wing type lead terminal (1b) of an IC device (1), a second contact terminal that contacts a J-type lead terminal, a cam portion (3d) and a sliding portion (15c5) for bringing the first contact terminal (15a) into contact with the gull wing type lead terminal (1b), and a latch (6) for bringing the second contact terminal into contact with the J-type lead terminal. An asynchronous operation in which a contact operation by the cam portion (3d) and the sliding portion (15c5) is performed after a contact operation by the latch (6) is performed.

Abstract: In a socket for electrical parts of the present invention, a fixed contact piece—a counterpart to the movable contact piece—is formed on a contact pin arranged on the socket body, a fixed-side contact portion which is designed to contact a lower side of the IC lead of the IC package is formed on the fixed contact piece, while a plurality of slits vertically penetrating a mold guide is formed spaced apart with a predetermined distance and the movable-side contact portions are inserted into slits respectively in order for an upper edge portion of the movable-side contact portion to be faced upward.
