Integrated circuit connector

摘要

A clamping lid for an electrical connector is disclosed, the connector being of the type intended for a rectangular integrated circuit package. The connector comprises a rectangular housing having a central well which receives the IC package and having contacts mounted in the side rails of the connector which engage the terminal pads on the IC package when it is placed in the well. The clamping lid comprises a flat stamped sheet metal member dimensioned to be mounted on the housing in covering relationship to the IC package. The lid is centrally open and has four side rails, three of these side rails having a pair of cantilever springs associated therewith. The springs of each pair extend from adjacent corners of the lid towards each other and overlap each other. These springs provide two zones or areas along each side rail in which clamping pressure is applied to the package. The fourth side rail has associated therewith a single clamping spring and a substrate biasing arm which engages one corner of the substrate when the lid is assembled to the housing and biases the substrate to a precisely predetermined position so that the contact terminals in the housing engage the terminal pads on the IC package substrate.
