Abstract
Provided is a heat sink clip for fastening a heat sink on a printed circuit board (PCB). The heat sink clip includes two hooks and a wire clip. The two hooks are inversely fixed to the PCB at two opposite sides of the heat sink. The wire clip includes a pressing wire pressing the heat sink, two pairs of deforming wires extending from the lateral of the pressing wire along two radial directions of the pressing wire and away from the PCB, and two engaging wires engaging with the respective hooks such that the deforming wires are bent towards the PCB.

A heat sink clip for securing a heat sink on a printed circuit board (PCB), the heat sink comprising a heat-transfer base in contact with the PCB and a plurality of fins extending up from a surface of the heat-transfer base opposite to the PCB, the heat sink clip comprising:
- two hooks for being arranged on the (PCB) at two opposite sides of the heat sink;
- and
- an elastic wire clip for being arranged between the fins, the wire clip comprising:
- a pressing wire for being placed on the heat-transfer base;
- two pairs of deforming wires extending from a lateral of the pressing wire along two respective radial directions of the pressing wire;
- and
- two engaging wires, each of which is positioned at ends of a corresponding pair of deforming wires distant from the pressing wire, each engaging wire configured to engage with a corresponding hook to force the corresponding pair of deforming wires to bend towards the heat-transfer base.
