ABSTRACT:
A connecting element for chip carriers comprises a unitary pin frame of insulating material and a set of contact elements which are secured within the frame by injection molding. Each contact element comprises a wire segment having a terminal end projecting from the bottom of the frame to connect with a printed circuit board, the wire segment including a portion extending upward from the frame to serve as a spring leg for connection with a contact surface of a chip carrier. Connection may be made by soldering. The chip may be supported either on top of or hanging below the carrier. The spring legs press laterally into semicircular cutouts on the sides of the frame. Posts are provided on the frame for restricting the insertion depth of the contact elements. The posts may be formed by injection molding and may be located at miter-joint areas of pieces of the pin frame.
