Description of the Invention: [Technical Field] The present invention relates to a fastening device, and more particularly to a heat sink fastening device for fixing a heat sink to a circuit board. [Prior Art] Generally, electronic components (such as a central processing unit) generate a large amount of heat when they are operated, and the temperature of the system itself and the system rises. If the temperature is too high, the running performance is degraded. For this reason, the industry usually installs a heat sink on an electronic component to discharge a large amount of heat generated. In order to ensure that the heat sink is in close contact with the electronic components and the heat transfer is sufficient, it is usually necessary to use a fastening device to assist in fastening the heat sink. As shown in the seventh figure, a heat sink clip is disclosed, which has a resilient arm 60, a first fastener 70, a second fastener 80, and a laterally fixed handle 90. The elastic arm 60 has an end. A receiving surface 61 is provided with two parallel slots 611, and the other end is bent to form a first fastening member 70. The second fastening member 80 has a pair of parallel plates 81, and a corresponding one of the upper portions of the pair of sheets 81 is respectively opened. The pivoting hole 811 has two eccentric wheel-shaped parallel plates 91. The eccentric position defines a pivot hole 911 corresponding to the pivot hole 811 of the two-piece body 81. The two pieces 81 of the second fastening member 80 pass through the two notches 611 of the receiving surface 61 of the elastic arm 60. The pivot shaft 93 passes through the pivot hole 81 of the second fastening member 80 and the lateral fixing handles 90. The pivot hole 911 pivots the second fastener 80 and the lateral fixing handle 90 together. 1315173 When the buckle is in use, the position of the frame hole 9 11 and the receiving surface 61 from the position of the lateral fixing handle 90 is turned to the farthest position of the pivot hole 9 1 and the receiving surface 61, thereby lifting up the second position. The fasteners are for installation purposes. However, when the buckle is in use, the lateral fixing handle 90 is liable to rebound due to system vibration to cause the buckle to accidentally fall off. Further, when the sheet body 91 of the lateral fixing handle 90 of the buckle is rotated, it is easily caught in the notch 611 on the receiving surface 61, thereby affecting the smooth installation of the buckle.

The bottom side of the first and second sheets 260 are connected by a connecting piece 240. When the eccentric wheel is rotated, the hooking is smoothly performed to further fix the device, the device and the handle 120, and the pressing portion f 120 - The first fastening hole 142 is formed into a slanted flat shape, and the first body body 220 and the top end 1315173 are respectively provided with corresponding pivot holes 262. The first body 220 and the second body 260 respectively correspond to the slots 162, and respectively pass through the slot 162 from below to position the two pivot holes 262 above the receiving surface 16A. A second buckle 280 is connected to the bottom end of the first body 220. The second fastening leg 280 is a long strip-shaped body </ </ RTI> provided with at least a second fastening hole 282. The bottom edge of the second cleat 280 is bent outward to form a chamfered chamfer. The handle 300 is integrally stamped from a metal piece, and includes a triggering portion 320 and two eccentric wheels 3 60 connected to the end of the triggering portion 320. The other end of the triggering portion 320 is provided with a plastic sleeve 400 which is easy to hold by hand. The two eccentric wheels 360 include two sheets of parallel and uniform in shape, and a pivot hole 362 is defined therein. A flat release section 364 and a curved fixed section 366 are provided at the edge of each eccentric 360. The distance from each point on the fixed section 366 to the pivot hole 362 is greater than the distance from each point 364 on the release section to the pivot hole 362. A bump 368 is punched from the inner and outer sides of the edge of the eccentric wheel 360 and the pivot hole 362 adjacent to the fixed section 366, respectively. The fixed section 366 of the two eccentric wheels 360 is folded outwardly from the outside to the inside to form a flange. The first piece 22 of the first fastening member 200 of the first piece and the second piece 260 of the first fastening member 200 pass through the slot 162 of the receiving surface 16 from the bottom to the bottom, and the pivot hole 262 of the first and second bodies 220 and 260. Located above the receiving surface 16〇. The handle 300 is located on the receiving surface 16〇 of the elastic arm 12〇, and is lost between the first and second bodies 22〇, 26〇10 1315173 of the second fastening component 200, and a pivot 500 passes through the handle 300. The pivot hole 362 and the pivot hole 262 of the first and second plates 220 and 260 pivotally connect the handle 300 and the second fastener 200 together, and the handle 300 protrudes laterally from the heat sink fastening device. One side. When the handle 3 00 is pulled, the release section 364 and the fixed section 366 of the eccentric 360 are selectively contactable with the receiving surface 16 6 of the resilient arm 1 2 . Regardless of the release section 364, the fastening section 366 is in contact with the receiving surface ι6, and the bumps 368 above the handle 300 are located beside the second and second bodies 220, 260 of the second fastener 2'. When the eccentric 36 turns into contact with the contact surface 16 from the fixed section 366 to the release surface 364 and contacts the contact surface I60, the bump 368 slides from the side of the first and second bodies 22, 26, to the other side. The side is combined with the side edges of the first and second sheets 22 〇 and 260, and the handle 300 is prevented from spontaneously rebounding due to the vibration. ‘,合詈仫詈仫田卡— Feng Invented Radiator Buckle The main purpose is to make the heat sink 2 shackle on the surface of the heat-35. The heat sink 2 is made of aluminum or copper: metal material including a heat generated by the electronic component 3=2:: the electronic component 35 is operated: and parallel arranged on the bottom plate 22 - the 22 heat sink fin An H^24 is opened in the middle of the sheet 24. These fastening devices. The electronic component 3=on the two-receiving heat sink number), and the i(four) circuit board (the un-standard seat 30俜-one rectangle; the frame body is provided with a ...3〇. The fixed-糸 rectangular body, the opposite two The sides are respectively provided with at least a convex 11 1315173 block 32, and the convex blocks 32 respectively correspond to the first and second fastening holes 142, 282 of the first fastening member ι and the second fastening member 200. When the heat sink fastening device straddles the long slot 26 of the heat sink 20, the handle 300 is pulled to rotate the eccentric 36 to the position where the release section 364 abuts the receiving surface of the elastic arm 120, and then the first The first fastening hole 142 of the fastening member 100 is sleeved to the corresponding protrusion 32 of the fixing base 30, and the second fastening hole 282 of the second fastening component 2 is sleeved to the corresponding protrusion 32 of the other side of the fixing base 3 ^The handle 300 is pulled to rotate the fixed section 366 of the eccentric 36 to the corresponding contact surface 16 of the first fastener 100. Since the distance of the fixed section 366 to the receiving surface 160 is smaller than the release section 364 to the receiving surface 160 The distance is large, so during the rotation of the handle 3〇〇, the eccentric 3 60 moves upward and lifts the second fastener 2〇〇, and simultaneously presses down The receiving portion 16 of the fastener 100 causes the pressing portion 122 of the first fastening member 1 to press downward against the bottom of the long slot 26 of the heat sink 10, so that the second fastening pin 280 of the second fastening member 200 The bumps 32 on the side of the fixing base 30 are firmly fastened, so that the heat sink 1 〇 is closely attached to the electronic component 35. At this time, the bump 368 on the handle 3 is just the first of the second fastener 200. The side edges of the same side of the two bodies 220 and 260 prevent the handle 3 from spontaneously rebounding due to system vibration, causing the kneading device to accidentally fall off. When disassembling, the handle 3 must be pulled first to make the eccentricity The wheel 306 rotates to a position where the release section 364 is in contact with the receiving surface 16〇 of the first-fastener ι〇〇', and simultaneously drives the second fastener 2〇〇 to move downward, 12 1315173 makes the second fastener 200 The buttonhole 282 is separated from the protrusion J of the fixing base 30 to facilitate the removal of the heat sink 20. The heat sink fastening device of the present invention adopts a flap having a flange and a 368 as a pivot structure of the eccentric 360 and the second fastener 200. The flange of the eccentric wheel 360 is folded inwardly to avoid the inner wall of the first and second bodies 266 of the second fastener 200 when the hand 3 00 rotates. Contact or jamming also avoids jamming into the notch 162 of the first fastener, thereby ensuring smooth running of the heat sink fastening device. The bump 3 6 8 on the handle 300 can also effectively handle the handle 300 due to the system. Vibrating and spontaneously rebounding causes the heat sink device to accidentally fall off, thereby improving the properties of the heat sink fastening device. In summary, the present invention meets the requirements of the invention patent and filed a patent application. However, the above description is only the present invention. For the embodiments, those skilled in the art of the present invention, equivalent modifications or variations in the spirit of the present invention, should be included in the scope of the following patents.
