Embodiment Construction

[0012] Please refer to FIG. 1 to FIG. 3 , the heat sink fixing device of the embodiment of the present invention is used to fix the heat sink 20 on the circuit board 30 so that the heat sink 20 is in close contact with the electronic components such as the central processing unit 32 .

[0013] A central processing unit 32 is installed on the circuit board 30 , and through holes 34 are symmetrically opened around the central processing unit 32 for the radiator fixing device to pass through.

[0014] The heat sink 20 includes a base 22 and a plurality of cooling fins 24 disposed on the base 22 . The base 22 respectively extends four fixing feet 222 (please refer to FIG. 1 ), and the fixing holes 224 corresponding to the through holes 34 of the circuit board 30 on the fixing feet 222 are provided with a fixing hole 224 for installing a radiator fixing device. The upper part is a hexagonal stepped hole 2241 with a larger diameter, and the lower half is a circular perforation 2242 ...

Abstract

A radiator fixture is used to fix a radiator on a circuit board to cool electronic components mounted on the circuit board. The radiator fixture includes a plurality of screws coated with elastic elements and capable of perforating through the radiator, sleeves for the screws to perforate through, and screw cylinders fixed relative to the circuit board and matched with the screws, wherein clasp rings are disposed on the screws, and inverse buckles matched with the clasp rings are disposed on the sleeves. The said radiator fixture uses the structure of disposing inverse buckles on the sleeves corresponding to the clasp rings on the screws, to connect the sleeves to the screws, which not only avoids the exposion of the thread on the screws to scrap the related electronic components, but also making the sleeves play a role of guidance when the screws points to the at the screw cylinders. In addition, when a radiator is installed, it is only needed to set a spring on the screw to make the clasp ring to drill through the inverse buckle, and then the radiator installation can be completed by screwing in a screw cylinder, thereby we can see that the radiator fixture is installation convenience, and security.

Description

【Technical field】 [0001] The invention relates to a fixing device, in particular to a radiator fixing device. 【Background technique】 [0002] With the rapid development of the computer industry, the operating capabilities of electronic components such as central processing units continue to improve, and their heat generation is also increasing. Heat dissipation has become a problem that must be solved when electronic components are used. At present, the industry generally installs a heat sink on the electronic components to dissipate heat. When installing the heat sink, a fastening device is required to fix the heat sink on the electronic components. [0003] In U.S. Publication No. 5,901,039, a screw-fit fastening device is disclosed, which has an externally threaded rod, which passes through the radiator from top to bottom, and after passing through the lower surface of the radiator, it abuts against the lower surface of the radiator A snap ring is snapped on the position...
