Land grid array connector with interleaved bases attached to retention frame

A Land Grid Array Connector comprising:

• a retention frame comprising a base portion defining a center opening and four sidewalls extending upwardly from the base portion;
• a socket received in the opening of the base portion and comprising at least two interleaved socket units each carrying a set of contacts to engage contacts of an IC and positioned within the retention frame such that the base portion of the frame surround the socket and such that edges carried by the socket are positioned opposite to edges carried by the base portion;
• and
• set of contacts carried by each of the socket units and each comprising contact portions exposed beyond the sockets units, the contacting sections of said at least two socket units extending in opposite direction, wherein the socket forms a plurality of positioning posts on the edges thereof, and wherein the retention frame defines a plurality of positioning holes adjacent to the opening receive the positioning posts of the socket, wherein the positioning holes of the retention frame define through the base portion along vertical direction, and wherein the positioning posts of the socket depending downwardly from outer periphery of the socket, wherein each positioning post occupies the positioning hole with free end extending beyond the lower surface of the base portion of the retention frame a certain distance, and wherein the free end of each positioning post is formed to have a diameter larger than that of the positioning hole, wherein the each one of the socket units forms a plurality of spaced apart body sections coplanar outwardly extending from the upper surface thereof, and wherein each positioning post extends downwardly from the body section, wherein the base portion defines a plurality of spaced apart cutouts communicate with corresponding positioning holes and that receive the body sections that of the socket.
