Creation instructions (1) [Technical field to which the new type belongs] This is about a radiator fastening device, especially a radiator fastening device that is fastened, fixed and easy to disassemble. [Previous technology] With the increase of chip computing speed and power consumption of electronic devices, the corresponding 5 heat generation has also increased sharply. In order to enable the chip to be knocked at the normal ICBC, a heat sink is often added on the surface of the chip. In time, the two Λπ # 4 of "", set. In order to achieve a close fit between the radiator and the chip ^ to say, the industry often uses a radiator fastening device to enclose the surface of the radiator on the surface of the king of the sun, which is not commonly used in the industry. A radiator fastening device, which includes a pair of spring nails 300 made of two oblique material X material 200 and a pair of springs 400. At the corners of the radiator 20? Pm, a lug 202 extends symmetrically outwards, and each lug 箬 has a through hole 204 through which the locking pin 300 passes. When assembling, first place the ammunition on your skin as the corresponding one. Lock pin 300, then lock pin 300 and spring 400: your miscellaneous teeth pass through hole 204 of heat sink 20 and hole 502 of circuit board 500, and then snap the circuit board. Through the elastic force generated by the locking pin 300 card and the deformation of the spring gang, the top surfaces of the "600", "600", and "600" are closely adhered together. The board 500 is as follows: the above-mentioned fixed structure, when The heat sink 200 needs to come out of the circuit, and the resistance is 4%. The locking pin 300 is not easy to pull from the hole 502 of the circuit board 500. In addition, the spring 4 has been used for a long time.

The push rod 42 includes a head portion 422, a rod-like portion 4 2 4 extending downward from the head portion 422, and a tapered portion 4 2 6 formed at an end of the rod-like portion 4 2 4. The top end of the tapered portion 426 is larger than the bottom end. The buckle 44 is made of an elastic material such as plastic, and includes a head 442, M249107, V. Creation Instructions (4), and a rod-shaped portion 444 extending downward from the head " 卩 442. A through hole 446 penetrates the head 442 and the rod-shaped portion 444 of the latching member 44 for the rod-shaped portion 424 and the cone 426 of the push rod 42 to be received therein. A pair of coaxial annular grooves 448 are defined in the lower surface of the head 442. The depth of each annular groove 448 gradually increases from point A to point B in its circumferential direction. A plurality of slots 450 are formed at the ends of the rod-shaped portion ⑷ opposite to the head portion 从而 so that a plurality of elastic latching pieces 452 are formed at the ends of the rod-shaped portion 444. Each elastic buckle piece 452 is formed with a corresponding inclined surface 454 at a position corresponding to the tapered portion 426 of the push rod 42. Each elastic buckle piece is provided with a ^ hook 456 at the end of its inner surface. At least two elastic buckle pieces 452 are provided with protrusions 458 on the outer surface of the end opposite to the hook 456. The distance from the outer surface of the protrusions 458 to the axis of the rod-shaped portion 444 is slightly larger than half of the second spring 48. control. At least two elastic buckle pieces 452 are provided with protruding ribs 459 on the inner surface thereof. The actuator 46 includes a cylindrical body 462 and a handle 463 formed on an outer surface of the cylindrical body 462. A pair of protruding posts 464 are formed on the top of the cylinder 462, and the pair of protruding posts 4 6 4 can be slid in the annular groove 4 4 8 corresponding to the head 4 4 2 of the fastener 4 4. A receiving cavity 466 is defined at the bottom end of the cylinder 462 for receiving the second spring 48 therein. A through hole 4 68 penetrates the cylindrical body 462 for the rod-shaped portion 444 of the fastener 44 to pass through. In the pre-installation, the first spring 47 is first sleeved on the rod-shaped portion 424 of the push rod 42 and is received together with the through-hole 446 of the fastener 44. Then, the rod-shaped portion 444 of the fastener 44 is passed through the through-hole 4 68 and the second spring 48 of the cylinder 462 of the actuator 46 in order. At this time, the second spring 48 is sleeved on the protruding block 458 of the rod-shaped portion 444 of the fastener 44 and presses the actuator 46 upward so that the protrusion 464 of the actuator 46 is received in the corresponding annular groove 448 of the fastener 44 The deepest point b, the entire M24 ^ 107. V. Creation instructions (5) The snap-fit structures 4 are pre-installed as a whole. Please refer to the fourth figure and the fifth figure. Above the chip 24 of the circuit board 2, heat dissipation is performed, and the heat dissipation state 1 is placed in the corresponding through hole 22 of the electric line in a straight line. 1 2 of the through hole 1 8 and the circuit board 2 HA ΑΛ ± ^ ^ ^ buckle, buckle of the force structure 4 4 of the rod-shaped mouth P 444, and the hook 456 at the end of the penetrating ... points ^ κ The political heat is that the back hole 3 of the base 12 and the back plate 3 of the back plate 3 and 6 phase buckle. With the same taste, .. ^ ^ ^ The yoke turns to the actuator 46, and its protrusion 464 slides from the deepest point A η & The actuating member 46 thus moves downwardly along the rod-shaped portion 444 of the buckling member 44 until it abuts the extension arm 18 of the heat sink 1. During the downward movement of the actuator 46, the second spring yellow 48 is squeezed, thereby generating an elastic force to press the radiator extension arm 8 downward. In this way, the heat sink 1 and the chip 24 of the circuit board 2 are closely adhered together by the abutting force of the actuator 46 and the elastic force of the second spring 48. When disassembling, press the head 422 of the push rod 42 downward, and the tapered portion 426 at the end of the push rod 42 presses the latch piece 452 at the end of the latch 4 to release the hook 4 of the latch piece 4 5 2 5 6 and the back plate 3 barb 36 6 buckle. The combination of the push rod 4 2, the latching member 44 and the actuating member 46 is moved upward by the elastic force of the second spring 48, so that the hook 4 5 6 of the latching member 4 4 is separated from the barb 36 of the back plate 3. The push rod 42 is reset by the elastic restoring force of the first spring 47. As another embodiment of this creation, the pushing structure that can push the fastener 44 upward when the actuator 46 is rotated: the positions of the protrusion 4 64 and the annular groove 448 can be interchanged, that is, the protrusion 464 is provided on the fastener The head 442 of 44 and the annular groove 448 are provided on the actuator 46.
