Abstract
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.

An electrical connector which comprises an insulator block having planar top and bottom faces with closely spaced bores therethrough connecting said faces, each bore having a conical lead-in mouth at the top face of the block and an elongated cylindrical portion of greater diameter than the inner end of the conical mouth together with a radial abutment shoulder between the top end of the cylindrical bore and the bottom end of the tapered mouth, a rigid machined tubular socket member in each bore with a top edge against the shoulder of the bore and having an outer diameter not less than the bore diameter for press fit engagement therewith and an inner diameter greater than the inner end of the tapered mouth thereby exposing the shoulder of the bore of the insulator block, said tubular socket member having a closed bottom end with a reduced diameter rigid pin extending beyond the bottom of the insulator block, a metal tubular contact element pressed into the upper end of the socket bore of each socket member with a top edge flush with the top edge of the socket member and bottomed against the exposed abutment shoulder, the combined thickness of the socket member and contact element being greater than the width of the radial abutment shoulder, the top end of said contact element being conically tapered to eliminate any internal abutment shoulder under the tapered mouth to cooperate with the tapered mouth for guiding an electrical component therein, the bottom end of said contact element having inwardly biased spring fingers for securing the electrical component in the socket member, and said reduced diameter pin end portion of the socket member extending beyond the bottom face of the insulator block in close relation with adjacent pins whereby the top face of the insulator block is free from projections, the tapered mouth and the tapered end of the tubular contact element in the tubular socket guide an electrical component into an engagement with the fingers and the projecting pins of the sockets provide closely spaced terminals.
