Patent ID: 7537429

Claim:
A method for fastening a fan, an elastic gasket and a fan holder together, the fan holder being used for attaching the fan to a heat sink for dissipating heat from an electronic device, the elastic gasket being sandwiched between the fan and fan holder, the fan, elastic gasket and fan holder each defining a plurality of fixing holes therein, the method comprising the steps of: a) providing a plurality of fasteners, each of the fasteners comprising a shaft, a handle, a head and a bulge, the handle extending from a first end of the shaft and having a diameter smaller than that of the shaft, the head being located at a second end of the shaft opposite to the first end and having a diameter larger than that of the shaft, the bulge being formed on the shaft, tapered along a direction from the head to the handle and adjacent to the first end of the shaft, a slot being circumferentially defined in the shaft just in front of the bulge and between the bulge and the head; b) inserting the handles through the fixing holes of the fan, the fixing holes of the elastic gasket and then the fixing holes of the fan holder until the handles of the fasteners project a distance beyond the fixing holes of the fan holder; c) pulling the handles of the fasteners to extend the first ends of the shafts of the fasteners beyond the fixing holes of the fan holder; and d) releasing the pulling force on handles of the fasteners so that the fan, the elastic gasket and the fan holder are tightly sandwiched between the heads and the bulges of the shafts of the fasteners, and finally cutting away the handles from the fasteners.
