Claims

[Scope of claim for utility model registration] A plurality of lead insertion holes with a diameter slightly larger than the lead pins of an IC and containing cylindrical contacts are opened on the top surface, and a plurality of socket pins connected to the above contacts are planted on the bottom surface. A plate-shaped socket that is slidably attached to the top surface of the lower part of the socket and has multiple lead insertion holes that are arranged in the same manner as the lead insertion holes and have a slightly larger diameter than the IC lead pins in the upper and lower surfaces. and a locking portion is provided by forming a concave part and a convex part relative to each other in the lower part of the socket and the upper part of the socket, and the lead insertion holes in the upper part of the socket and the lower part of the socket are misaligned to prevent the lead pins of the IC from being inserted. An IC socket characterized in that the concave portion and the convex portion engage with each other when the IC socket is held in the sliding direction.
