ABSTRACT:
A locking device is used for securing a heat sink to an electronic device mounted on a first face of a printed circuit board which defines a first hole. The heat sink defines a second hole therein. The locking device has a fastener including a head portion located aside the heat sink, a foot portion located aside a second face of the printed circuit board, and a body portion extending through the holes of the heat sink and the printed circuit board and interconnecting the head portion and the foot portion. The foot portion includes a buckling part abutting against the second face of the printed circuit board, and a positioning part extending towards the head portion to a position above the buckling part. When the buckling part abuts against the printed circuit board, the positioning part has a portion thereof entering into the first hole.
