Heat sink fastener

Abstract

A fastener for fixing a heat sink on an electronic component is disclosed. The fastener includes a frame seat, a latch and two depressors. The frame seat is formed with a hollow for accommodating the heat sink and the latch is moveably mounted on the frame seat. The depressors may be selectively pressed or released by the latch against the frame seat. The heat sink can be fastened by the depressors when the depressors are pressed by the latch.

1 . A heat sink fastener comprising:
 a frame seat having a hollow for accommodating a heat sink;   a latch movably rotatably assembled on the frame seat; and   a depressor;   wherein the latch is capable of pressing and releasing the depressor between the frame seat and the depressor, and the depressor exerts pressure on the heat sink when the latch presses the depressor.   
     
     
         2 . The heat sink fastener of  claim 1 , wherein the frame seat is provided with a plurality of fixing holes separately passed by flexible fixers. 
     
     
         3 . The heat sink fastener of  claim 1 , wherein the frame seat is provided with a nut post, the latch is provided with a fixing hole corresponding to the nut post, and a bolt passes through the fixing hole to screw into the nut post when the latch is pressing the depressor. 
     
     
         4 . The heat sink fastener of  claim 1 , wherein the latch is of a U shape. 
     
     
         5 . The heat sink fastener of  claim 4 , wherein two ends of the U-shaped latch are separately formed with two pressing portions pressing the depressor. 
     
     
         6 . The heat sink fastener of  claim 4 , wherein two ends of the U-shaped latch are separately formed with two protrusions, the frame seat is formed with two opposite side walls on two edges of the hollow, each of the side walls is provided with a receiving hole for receiving the protrusions. 
     
     
         7 . The heat sink fastener of  claim 6 , wherein each of the protrusions is further extended with a protrudent hook. 
     
     
         8 . The heat sink fastener of  claim 6 , wherein an upper edge of the receiving hole is formed with a progressively rising slant. 
     
     
         9 . The heat sink fastener of  claim 1 , wherein the depressor is a zigzag plate. 
     
     
         10 . The heat sink fastener of  claim 9 , wherein the zigzag depressor includes an upper pressed section and a lower pressing section, the pressed section is pressed by the latch, and the pressing section overlaps the heat sink. 
     
     
         11 . The heat sink fastener of  claim 9 , wherein the pressed section is further extended with a connecting section having a connecting hole, the frame seat is provided with a connecting sheet inserted into the connecting hole. 
     
     
         12 . The heat sink fastener of  claim 9 , wherein the depressor is provided with a threaded hole for being fixed on the heat sink.
