As shown in fig. 5 and 6, the exterior of the sleeve 3 is provided with a boss 31, and as can be seen from fig. 2, 3 and 4, the first compression spring 5 is located between the boss 31 and the heat sink 2, so that the first compression spring 5 supports the heat sink 2 and controls the up-and-down movement of the sleeve 3, that is, the first compression spring 5 is sleeved outside the sleeve 3, and the lower end of the first compression spring 5 is in contact with the top of the boss 31; the upper end of the first compression spring 5 is in contact with the bottom of the heat-dissipating substrate 21. In the process of mounting the CPU heat sink, when the screw tail portion 43 is inserted into the rivet stud 1 and screwed into the rivet stud 1, the degree of compression of the first compression spring 5 gradually increases. In the process of disassembling the CPU heat sink, the screw tail 43 is unscrewed from the rivet stud 1, and since the first compression spring 5 is released, a tendency to push the heat sink 2 upward may be generated, and the heat sink 2 may be more conveniently disassembled.
The second compression spring 6, as shown in fig. 2, 3 and 4, the second compression spring 6 is sleeved on the screw rod portion 42, i.e. the second compression spring 6 is arranged outside the screw rod portion 42 and between the screw head portion 41 and the heat sink 2, so that the second compression spring 6 supports the screw head portion 41 and controls the up-and-down movement of the screw 4. The screw 4 further comprises a screw head 41, the screw head 41 being provided with a T-shaped recess. The screw shank 42 is between the screw head 41 and the screw tail 43. In the process of disassembling the CPU heat sink, the screw tail 43 is unscrewed from the rivet stud 1, and the second compression spring 6 is released, so that a tendency of pushing the heat sink 2 upward can be generated, and the heat sink 2 can be more conveniently disassembled. Wherein, the first compression spring 5 and the second compression spring 6 are respectively arranged at two ends of the through hole 24.
A washer 7, as shown in fig. 2, 3 and 4, the washer 7 is disposed outside the screw shank 42 and between the second compression spring 6 and the heat sink 2. The washer 7 is disposed between the second compression spring 6 and the heat sink 2 in order to prevent the second compression spring 6 from passing through the through hole 24.
With reference to fig. 2, 3 and 4, the process of mounting the heat sink 2 on the CPU socket is as follows:
the sleeve 3 is sleeved outside the press riveting stud 1, the screw tail part 43 of the screw 4 sequentially passes through the second compression spring 6, the washer 7, the sleeve 3 (which passes through the sleeve 3 and simultaneously equivalently passes through the through hole 24) and the first compression spring 5 from top to bottom, and is inserted into the press riveting stud 1, under the absence of external force, due to the elastic forces of the first and second compression springs 5 and 6, so that the screw tail part 43 cannot contact with the rivet pressing stud 1, in order to connect the screw tail part 43 with the rivet pressing stud 1, the screw 4 needs to be compressed downwards, the second compression spring 6 and the first compression spring 5 enter a compressed state, and as the compression degree increases, the screw tail part 43 contacts with the rivet pressing stud 1, the screw 4 rotates downwards along with the contact, so that the screw tail part 43 and the rivet pressing stud 1 can be engaged through threads, and the heat sink 2 is further installed on the CPU slot through the screw 4.
With reference to fig. 2, 3 and 4, the process of detaching the heat sink 2 from the CPU socket is as follows:
rotating the screw 4 upwards to disconnect the screw tail 43 from the screw thread between the rivet pressing stud 1; under the condition of no external force, the compression degree of the first compression spring 5 and the second compression spring 6 is reduced, so that the distance between the screw tail part 43 and the rivet pressing stud 1 is increased; the screw tail part 43 is sequentially drawn out from the sleeve 3, the first compression spring 5, the through hole 24, the gasket 7 and the second compression spring 6, so that the purpose of disassembling the radiator 2 can be achieved.
In summary, the present application provides the screw assembly (specifically, the screw 4, the second compression spring 6, the washer 7, the via hole 24 of the heat dissipation substrate 21, the first compression spring 5, and the sleeve 3), and the heat sink 2 is mounted through the screw assembly and the press-riveting stud 1 of the CPU socket. This application uses the pressure riveting double-screw bolt 1 on the CPU slot as positioner, rivets the double-screw bolt 1 outside with sleeve 3 cover in the pressure, can realize radiator 2's installation location fast, shortens installation time, avoids installing repeatedly, reaches the purpose that improves the installation effectiveness, reduces installation cost. By arranging the first compression spring 5 and the second compression spring 6, the screw 4, the radiator 2 and the press riveting stud 1 can be ensured to be fastened more depending on the elasticity of the springs in a compressed state, and the purpose of fastening and mounting the radiator 2 is further achieved; and when the radiator 2 is disassembled and the screw 4 is screwed out of the press riveting stud 1, the screw 4 is automatically separated from the contact of the press riveting stud 1 by virtue of the restoring force of the first compression spring 5 and the second compression spring 6, so that the radiator 2 is more convenient and quicker to disassemble.
On the basis of the technical scheme, the application further provides the following optimization scheme:
a CPU heat sink mounting structure for use with AMD platforms further comprising: a spacer 8.
As shown in fig. 8, the gasket 8 is an open-type gasket 8, the inside of the gasket 8 is provided with a latch 82, and the outer edge of the gasket 8 is provided with a first protrusion 81. As shown in fig. 7, the screw shank 42 is provided with an annular groove 44. As shown in fig. 2, 3 and 4, the pad 8 is clamped against the annular recess 44 by means of the latch 82. The diameter of the screw shank 42 at the annular groove 44 may be 3mm, with a circular platform 1.4mm thick between the annular groove 44 and the location where the screw tail 43 is threaded (the threads may be M3 x 0.5); the screw shank 42 outside the annular groove 44 may have a diameter of 3mm and a length of 5.5 mm.
As shown in fig. 5 and 6, the sleeve 3 is provided with a strip-shaped groove 33 and an annular protrusion 32 inside (the annular protrusion 32 may be chamfered to facilitate the screw tail 43 to better enter the sleeve 3). The strip-shaped groove 33 is matched with the first projection 81.
The gasket 8 is inside the sleeve 3 on the side of the annular projection 32 remote from the heat sink 2, the first projection 81 being embedded in the strip-shaped groove 33, so that the screw tail 43 cannot come off the sleeve 3 when the gasket 8 is clamped in the annular groove 44. Since the first projection 81 is engaged in the strip-shaped groove 33 and the washer 8 is fixed in the annular groove 44 by the latch 82, the first projection 81 is restricted from rotating when the first projection 81 is engaged in the strip-shaped groove 33, i.e. the sleeve 3 and the washer 8 are rotated together when the screw 4 is rotated.
To more clearly illustrate the mounting location and function of the spacer 8, the following description is now made in connection with the mounting process of the heat sink 2 (in connection with fig. 2, 3 and 4):
the screw tail portion 43 of the screw 4 sequentially passes through the second compression spring 6, the washer 7, the through hole 24, the first compression spring 5 and the sleeve 3 from top to bottom (at this time, the upper end of the sleeve 3 does not pass through the through hole 24 due to the elasticity of the first compression spring 5), after an external force is gradually applied, namely, a force towards the screw tail portion 43 is applied to the screw head portion 41, so that the second compression spring 6 and the first compression spring 5 are in a compression state, along with the increase of the compression degree, the upper end of the sleeve 3 passes through the through hole 24, the screw tail portion 43 passes out from the lower end of the sleeve 3, at this time, the gasket 8 is clamped on the outer surface of the annular groove 44 of the screw rod portion 42, and the first protrusion 81 of the gasket 8 is embedded into the strip-shaped groove 33 inside the. At this time, the application of the external force to the screw 4 is stopped, and the first compression spring 5 and the second compression spring 6 are extended by the restoring force and bring the spacer 8 into the interior of the sleeve 3. Since the annular projection 32 is provided inside the sleeve 3, the range of motion of the gasket 8 inside the sleeve 3 is trapped only between the annular projection 32 and the lower edge of the annular groove 44. The screw tail 43 cannot be detached from the sleeve 3 due to the fact that the gasket 8 is clamped on the outer surface of the annular groove 44, and therefore the second compression spring 6, the washer 7, the through hole 24, the first compression spring 5 and the sleeve 3 are connected into a whole. The lower end of the sleeve 3 is sleeved outside the rivet pressing stud 1, and a force towards the screw tail portion 43 is applied to the screw head portion 41, so that the screw tail portion 43 is in contact with the rivet pressing stud 1, at this time, the screw 4 is rotated downwards, so that the screw tail portion 43 and the rivet pressing stud 1 are engaged through threads (meanwhile, as the first protrusion 81 is embedded into the strip-shaped groove 33, the gasket 8 and the sleeve 3 are rotated together while the screw 4 is rotated), and then the heat sink 2 is installed on the CPU socket through the screw 4, as shown in fig. 9 finally.
Correspondingly, with reference to fig. 2, 3 and 4, the process of disassembling the heat sink 2 is as follows:
upwards rotate screw 4 for screw 4 breaks away from with the screw thread of rivet pressing double-screw bolt 1, because the restoring force of second compression spring 6 and first compression spring 5, break away from in via hole 24 is followed to the upper end of sleeve 3, and the distance between screw 4 and the rivet pressing double-screw bolt 1 increases simultaneously, at this moment, only need take up radiator 2, just can directly dismantle radiator 2, and the screw subassembly that the dismantlement obtained still is in via hole 24 department of radiator 2. At this point, the resulting heatsink 2 may be mounted directly on a CPU socket provided by the additional AMD. If the screw assembly is to be detached from the heat sink 2, a force toward the screw tail 43 is applied to the screw head 41, so that the second compression spring 6 and the first compression spring 5 are in a compressed state, and the screw tail 43 passes through the sleeve 3 with increasing degree of compression, at this time, the gasket 8 is removed from the annular groove 44 of the screw rod portion 42, and the screw tail 43 can be sequentially removed from the sleeve 3, the first compression spring 5, the through hole 24, the washer 7 and the second compression spring 6, so as to achieve the purpose of detaching the screw assembly.
It can be seen that the second compression spring 6, the washer 7, the first compression spring 5, the sleeve 3 and the washer 8 provided by the present application can constitute a screw assembly, and one screw assembly can be matched with one rivet pressing stud 1, namely, the number of the through holes 24, the number of the sleeves 3 and the number of the screws 4 are equal to the number of the rivet pressing studs 1. Typically, four screw assemblies may be used to mount the heat sink 2 of a CPU.
In summary, the present application provides a screw assembly, which is installed on the via hole 24 of the heat dissipation substrate 21 in advance, when the CPU is needed to install the heat sink 2, the sleeve 3 in the screw assembly can be sleeved outside the press riveting stud 1, and the screw 4 is pressed downward, so that the screw tail 43 and the press riveting stud 1 are engaged with each other through threads, and the purpose of installing the heat sink 2 is achieved.
