Abstract: The present invention aims to improve heat dissipation effect for an electrical component in a socket for electrical component in which a socket body and a cover member are separated. According to an embodiment, a cover member includes a frame-like cover body including an opening in a middle portion thereof, a heatsink provided to penetrate through the opening of the frame-like cover body, an elevating part supporting the heatsink, and a pressing part that is moveable to press the elevating part so as to press the heatsink against the electrical component. While the heatsink is pressed against the electrical component, the electrical component is fixed to the housing portion of the socket body. Accordingly, it is possible to make the heatsink perform heat dissipation for the electrical component. Thus, it is possible to obtain excellent heat dissipation effect with respect to the electrical component.

Abstract: A socket for electrical component capable of pressing and fixing an electrical component.A pressing part includes a first cam rotatably supported by the body part, and a second cam supported by the first cam. An elevating part includes a cam locking part provided on a rotational orbit of the second cam. A tip of the second cam is formed such that the tip of the second cam passes over the cam locking part when the elevating part is moved down by making the tip of the second cam abut against the elevating part and rotate, and the tip of the second cam is locked by the cam locking part so as to prevent the rotation when an attempt is made to perform the rotation in the opposite direction. The rotation in the opposite direction is enabled by moving the second cam in the radial direction of the rotation.

Abstract: A contact pin to electrically connect a first electrical component to a second electrical component and contact with the first and second electrical components at a sufficiently large contact pressure. The contact pin includes a first plunger with a first contact portion and a second plunger with a second contact portion. An expandable meander portion is formed on the second plunger. A contact piece to conduct electricity between the first and second plungers is provided to guide the expanding and shrinking operation of the meander portion. The first and second plungers are conducted via the contact piece when the first electrical component is electrically connected to the second electrical component, and the meander portion is shrunk to bring the first contact portion of the first plunger and the second contact portion of the second plunger into contact with the first and second electrical components at a sufficiently large contact pressure.
