Heat sink and retainer for electronic integrated circuits
First Claim
1. In combination, a heat sink and a heat sink retainer clip for use in conjunction with an electronic device, such as a semiconductor, to provide cooling of the device, the device being mounted on a rectangular socket with opposing sidewalls, at least two opposed side walls having lugs protecting laterally outward from the walls, the heat sink comprising a flat plate with a plurality of fins protecting upwardly from the top surface of the plate, a central section of the plate being free of the fins to receive the clip, the retainer clip comprising:
- a first member including a retaining portion and a biasing portion;
(i) said biasing portion received in said central section of the plate and extending substantially across the plate for biasing the heat sink against the device;
(ii) said retaining portion having an opening for receiving the lug on the socket side wall and connected to said biasing portion adjacent one end thereof;
(iii) said biasing portion, at the end opposite to the retaining portion, being bifurcated to form two arms adjacent the free end; and
a second member, rotatably and loosely supported by the free end of said biasing portion, including at least two openings, a lower of said openings for receiving the lug on the opposite side wall of the socket, the upper opening receiving the free ends of the arms on the biasing member.

Abstract
A heat sink and retainer clip for use in conjunction with an electronic integrated circuit, such as a semiconductor device, to provide cooling of the device, the device being mounted on a rectangular socket with opposing sidewalls and at least two of the sidewalls having lugs projecting laterally outward. The heat sink has a flat plate and a plurality of fins projecting upward from the top surface, except over the central portion of the plate. The retainer clip is constructed of two pieces. One piece is an elongated strap having a bent portion that bears down on the heat sink to force it into a heat conducting relationship with the device and also includes an opening that is hooked on the one of the lugs. The strap lies in the central portion of the sink. The second piece is rotatably mounted on the end of the first piece and when forced down and rotated inward, an opening will hook on the other lug.
