Abstract: There is disclosed herein a dual-in-line socket assembly which includes an insulator block having a plurality of socket-receiving apertures therein, each aperture adapted to receive an electrical socket. Each aperture has at one end a conically-shaped pin-receiving lead-in taper which opens into a cylindrical socket-receiving portion. An internal abutment shoulder is defined within the aperture at the junction af the lead-in taper and the socket-receiving portion. Electrical connector sockets are adapted to fit within the socket-receiving portion for receiving and electrically contacting a pin from an electrical device such as an integrated circuit chip.
