[Embodiment] Referring to Figure 1, a preferred embodiment of a heat sink fixture of the present invention is used to secure a heat sink 10 to a circuit board. The heat sink fixture includes a fastener assembly 20, a gasket 30, a spring 40, and a card 50. The heat sink 10 includes a base 12 and heat dissipation fins 14 vertically disposed in a middle portion of the base 12. A through hole 120 is defined in each of the four corners of the base 12. The card 50 has a circular arc shape and is provided with a bayonet 52 for snapping the fastener assembly 20. Referring to FIG. 2 to FIG. 4 together, the fastener assembly 20 includes a connecting member 22, a fixing member 24 fixed to the connecting member 22, and a sliding receiving member on the solid 099146025. Form No. 1010101 Page 5 of 17 0992079173-0 [0010] 201226729 The slider 26 of the holder 24 and a set of elastic members 28 provided on the slider 26. In the embodiment, the elastic member 28 is a spring. [0011] The connector 22 includes a head 220 and a cylindrical connecting portion 222 extending from the head 220. A fixing groove 224 is axially disposed at one end of the connecting portion 222 away from the head portion 220. The head 220 is provided with a receiving hole 225 extending along the axial direction of the connecting portion 222 until it communicates with the fixing groove 224. The connecting portion 222 forms a stepped surface (not labeled) adjacent to the fixing hole 224 and the receiving hole 225. [0012] The fixing member 24 includes a body 242 and a first fixed end 246 having an external thread extending from opposite ends of the body 242 and a second fixed end 244 having an external thread. The body 242 is provided with a receiving slot 247 extending through the second fixed end 244. The second fixed end 244 has a diameter substantially equal to the diameter of the fixing groove 224. A card slot 248 is formed in the periphery of the body 242. The first fixed end 246 is provided with a through hole 249 extending along the axial direction of the first fixed end 246 until it communicates with the receiving slot 247. The body 242 is disposed in the receiving slot 247 and the through hole 249. The abutment forms a stepped surface (not labeled). [0013] The slider 26 includes a stem portion 262 and a stopper portion 264 protruding from a periphery of the stem portion 262. The stop portion 264 is adjacent to the first end of the stem portion 262. [0014] When the fastener assembly 20 is assembled, the elastic member 28 is sleeved from the second end of the rod portion 262 to the stem portion 262 of the slider 26. The second end of the sliding member 26 is slid through the receiving slot 247 of the fixing member 24 and exposed from the through hole 249 of the fixing member 24 to the first fixing end 246 of the fixing member 24. At this time, the two ends of the elastic member 28 can respectively contact one end of the stopper portion 264 and the step surface of the connector 22 of the form number 010146025 Form No. A0101 Page 6 of 17 0992079173-0 201226729. The second fixing end 244 of the fixing member 24 is screwed into the fixing groove 224' of the connecting member 22, and the first end of the rod portion 262 is received in the receiving hole 225 of the connecting member 22. The other end of the stopper portion 264 can contact the stepped surface of the fixing member 24. [0015] 再次 Referring again to FIG. 1 , when the fastener assembly 20 is assembled on the heat sink 1 , the spacer 30 and the spring 40 are sequentially sleeved on the connecting member 22 of the fastener assembly 2 ′. The fastener assembly 20 is passed through the through hole 120 of the heat sink 1〇. The card 50 is engaged with the card slot 248 of the fastener assembly 20 from the bottom of the base 12 of the heat sink 10 and abuts against the bottom of the base 12 to fix the fastener assembly 20 to the heat sink. 1〇. At this time, the spacer 3 抵 abuts the head 220 of the fastener assembly 20. The opposite end of the spring 40 elastically abuts the spacer 30 and the base 12 » [0016] corresponding to the fastener assembly 20', the circuit board can be provided with a plurality of blind holes, and the blind holes can be combined with the fastener The first fixed end 246 of the 20 is fitted with an internal thread of the file. When the heat sink 10 is assembled to the circuit board, the first fixed end 246 of the fastener assembly 20 is threaded into a blind hole of the circuit board. At this time, the bottom of the blind hole of the circuit board abuts the second end ' of the rod portion 262 of the slider 26 of the fastener assembly 2 to force the first end of the rod portion 262 toward the head of the connecting member 22 220 sports. When the first end of the stem portion 262 is flush with or protrudes from the head portion 22, it indicates that the fastener assembly 2 is locked in place. During this process, the elastic member of the fastener assembly 2 is "squeezed and deformed". Both ends of the elastic member 28 elastically abut against the stopper portion 264 and the stepped surface of the connecting member 22. The elastic member 28 generates Elastic deformation to facilitate the reset of the slider 26. 099146025 In other embodiments, the circuit board can also be provided with a plurality of through holes, form number Α0101, page 7 / 17 pages for 0992079173-0 [0017] 201226729 The fastener combination The first fixed end 246 of the 20 is passed through. A side of the circuit board facing away from the fastener assembly 20 is fixedly provided with a back plate, and the back plate is provided with a plurality of blind holes, and the blind holes are disposed in combination with the fastener 20 The first fixed end 246 is fitted with an internal thread to fix the first fixed end 246. [0018] In other embodiments, the circuit board may also be provided with a plurality of through holes, and the first fixed end 246 of the fastener assembly 20 Through the through holes, a one end closed fastener is fixed to the end of the first fixed end 246 to fix the first fixed end 246. [0019] Obviously, as described above, the fastener combination 20 The first fixed end 246 can be fixed to any one Fixing member, as long as the fixing member is provided with a blind hole 〇 [0020] In summary, the present invention complies with the invention patent requirement, and patent application is filed according to law.
