ABSTRACT:
A fastener (10) for mounting a heat-radiator (20) to an electronic device (30) on a circuit board (40) is disclosed. The heat-radiator and the circuit board have aligned holes (22, 44). The fastener includes a head (11) having an upper portion (112) with a large diameter and a lower portion (113) with a smaller diameter, a cylindrical spring (14) captured around the lower portion of the head for exerting a spring force against the heat-radiator, and a metallic wire (15) having a first end portion fixed on said head and a second end portion bent to form an engaging portion (152). The engaging portion of the metallic wire compressively passes through the aligned holes of the heat-radiator and the circuit board and is engaged with an underside of the circuit board.
