Embodiment Construction

[0015] see Figure 1 to Figure 2 , The radiator fastening device 10 of the preferred embodiment of the present invention includes a first fastener 100 , a second fastener 200 , a connecting piece 300 and a screw 400 . Wherein the first fastening member 100 has a resisting member 120, the resisting member 120 is bent in a V shape, a resisting portion 122 is formed in the middle, and a through groove 124 is opened in the middle, and one end is bent downwards and extended to form a second One buckle foot 140. The first buckle foot 140 is a strip-shaped piece with a first buckle hole 142 formed thereon, and the bottom of the first buckle foot 140 is bent outward to form an oblique chamfer. The other end of the pressing member 120 is provided with a horizontal joint portion 160 , and a pair of parallel slots 162 are defined on the joint portion 160 with the same shape and size.

[0016] The second fastener 200 has a first sheet 220 and a second sheet 260 . The first and second p...

Abstract

A fastening device for a radiator, comprising a first fastener and a second fastener, one end of the first fastener is provided with a buckle foot downward, the second fastener is passed through the other end of the first fastener, There is a second buckle foot below it, and also includes a connecting piece and a screw piece; the connecting piece is fixed on the second fastener piece, and a screw hole is opened on it; the screw piece is provided with two threaded sections and a non-threaded section , wherein the unthreaded section is arranged between two threaded sections, the screw member is rotatably arranged in the screw hole of the fixing member, and the threaded section and the unthreaded section selectively cooperate with the screw hole to adjust the screw member The relative positional relationship between the bottom end and the first fastener. This embodiment is connected with the above-mentioned radiator fastening device through the connecting piece and the second buckle, and the screw is installed on the connecting piece through the screw hole on the connecting piece so that the bottom of the connecting piece is pressed against the first buckle, and then the screw thread on the screw is controlled. The screw-in length is used to adjust the height at which the screw member presses down on the first fastener to drive the second fastener to move upwards, thereby controlling the buckling force so that the heat sink and the electronic components are in close contact.

Description

【Technical field】 [0001] The invention relates to a fastening device, in particular to a fastening device for fixing a heat sink for cooling electronic components on a circuit board. 【Background technique】 [0002] Generally, electronic components (such as a central processing unit) generate a lot of heat during operation, which increases the temperature of itself and the system. Excessively high temperatures will degrade its operating performance. For this reason, the industry usually installs heat sinks on electronic components to dissipate the large amount of heat generated by them. In order to ensure that the heat sink and the electronic components can be in close contact and heat transfer is sufficient, it is usually necessary to use a fastening device to assist the fastening of the heat sink. [0003] Such as Image 6 As shown, a radiator buckle is disclosed, which has: a buckle rod 51, and a buckle arm 511 is bent and extended at both ends thereof, so as to be hooked...
