Abstract

Socket for receiving edge of a chip carrier substrate comprises a dielectric housing having an elongate channel interrupted by partitions having aligned U-slots which limit position of substrate. Cavities separated by the partitions receive U-shaped contacts each having a base with directly opposed arms formed upward therefrom and a flat pin formed downward therefrom and extending into respective apertures in the floor of the channel. Arms present convex rolled inside surfaces to opposed surfaces of substrate for electrical contact therewith. Floor of channel has convex portion in each cavity on which base rocks as pin deflects resiliently in chamfered lead-in to aperture to accommodate any substrate warpage. Profile of U-slot in partition prevents stressing of arms beyond elastic limit.
