Description of the Invention: [Technical Field of the Invention] [0001] The present invention relates to a holding device 'for providing a clamping force for two objects to be joined. [Prior Art] [0002] The heat dissipation module is widely used in the field of heat dissipation to dissipate heat for electronic devices such as notebook computers. The plurality of heat dissipation modules include a heat absorbing plate for absorbing heat from the heat generating electronic components, a heat sink for dissipating heat, and a heat pipe connected to the heat absorbing plate and the heat sink to transfer heat on the heat absorbing plate to the heat sink. Therefore, the interface thermal resistance between the heat pipe and the heat absorbing plate directly affects the efficiency of heat transfer from the heat absorbing plate to the heat pipe. [0003] Generally, a heat pipe is connected to a heat absorbing plate by soldering. The quality of the soldering effect depends largely on whether the heat pipe and the heat absorbing plate are always in close contact during the soldering process. Conventional processes often provide a clamping force through a clip such as a dovetail clamp to keep the heat pipe in close contact with the heat absorbing plate during the melting and recrystallization of the solder paste. However, due to cost considerations, these clips will be recycled. 9 On the one hand, the elasticity of the lost one will be rescued due to the use of pumping, and the clamping force provided will also become smaller, which may eventually lead to heat pipe and heat absorption. The contact of the board is not tight enough, which affects the soldering effect and increases the thermal resistance of the interface. On the other hand, with the continuous disposal of the old clips and the use of new clips, the elastic force of the clips is greatly different, and the grip provided by each clip Forces vary in size and ultimately lead to differences in product quality. SUMMARY OF THE INVENTION [_] Li is here, it is necessary to provide a scale device having a uniform-clamping force. 099111530 Form No. A0101 Page 3 of 15 0992020396-0 201135080 [0005] A clamping device comprising: a body, a mother and a wire, the body being provided with a connecting screw through hole fixed to the body, The connecting nut is disposed in the inner hole of the body of the body in the axial direction of the nut. The screw is inserted through the screw and is mutually perforated, and a clamping space is formed between the material (4) and the body. [0007] [0009] [0009] The screw that holds the garment lowers the desired object to the body to provide a - clamping force. Since the coupling nut limits the movement of the screw, the loss of force is attenuated by the influence of the brother. Therefore, the holding device can provide a uniform clamping force. [Embodiment] Please refer to Figs. 1 and 2, which show a lost device (10) according to an embodiment of the present invention. The clamping device 100 includes a body 10, a nut assembly 20 secured to the body 10, and a screw 3 conjugated to the body assembly 20 for attachment to the body 10. The body ίο is u-shaped. The body 10 includes a rectangular abutting portion 12, a branch portion 丨4 spaced apart from the D-hai abutting portion 12, and a connecting portion 15 connecting the abutting portion 和2 and one end of the supporting portion 14. The abutting portion 12 is disposed in parallel with the support weir 14. The body 1 is formed with an opening 11 at the other end of the abutting portion 12 and the supporting portion 14. A circular through hole 13 is formed in the support portion 14 near the opening 11 of the body 1''. The β-heel nut assembly 2 includes a coupling nut 22, a nut 24 and a resilient pad 099111530 piece 26. The coupling nut 22 includes a cylindrical screw 224 and a disc-shaped end 222 at the bottom of the screw 224. Wherein, the outer diameter of the screw 224 is smaller than the diameter of the through hole 13 of the support portion 14, and the outer diameter of the end portion 222 is larger than the diameter of the through hole 13 form tar number A0101. The length of the screw 224 is much larger than the thickness of the support portion 14 page 4 / total 15 pages 0992020396-0 201135080 degrees. The coupling nut 22 has a hollow shape, and a central portion thereof defines a through hole 220 that penetrates the thread 224 and the end portion 222 in the axial direction. The size of the aperture of the perforation 220 is constant along the axial direction of the coupling nut 22, i.e., the aperture of the perforation 220 at the screw 224 coincides with the aperture at the end 222. The inner surface of the coupling nut 22 is formed with an internal thread at the periphery of the through hole 220. An external thread is formed on the outer surface of the screw 2 24 of the coupling nut 22. [0011] [0012] The nut 24 has a hollow cylindrical shape, and an inner surface thereof is provided with an internal thread. The internal thread of the nut 24 is matched with the external thread of the screw 224 of the coupling nut 22, so that the nut 24 can be closely fitted with the coupling nut 22, and the elastic gasket 26 is in the shape of & The pressure along the axial direction is compressed. The outer diameter of the nut 24 and the elastic spacer 26 are both larger than the diameter of the through hole 13. "Hui screw 30 includes an elongated bolt 34 and a threaded head 32 attached to the top of the bolt 34. The length of the bolt 34 is greater than the length of the coupling nut 22. The outer diameter of the bolt 34 is approximately the same as the diameter of the bore 22 of the coupling nut 22. The outer surface of the bolt 34 is provided with a thread, and the thread on the bolt 34 matches the internal thread of the coupling nut 22. The diameter of the screw head is larger than the diameter of the bolt 34. Please - and _3 'assemble the clamping device 1Q (4), and thread the screw 224 of the coupling nut 22 from the bottom to the top of the body 1 In the punched through hole 13, the end portion 222 abuts against the lower surface of the periphery of the through hole 13 of the supporting portion 14, and the elastic cymbal 26 is sleeved on the screw 224 of the coupling nut 22 from above the cutting portion 14. 'The nut 24 is screwed from above onto the screw 224 of the coupling nut 22. When the nut 24 is fully tightened, the elastic spacer 099111530 26 is sandwiched between the nut 24 and the branch portion 14. And is pressed by the nut 24 to produce an elastic deformation and is (4) 'butted against the cut (four) in the through hole _ form number A0101 page 5 / total 15 page 0992020396-0 201135080 edge of the upper surface. At this time, the connection nut The end portion 222 of the 22 abuts against the lower surface of the support portion 14 such that the nut assembly 2 is firmly fixed to the branch portion 14. [0013] [0015] In addition, since the elastic spacer 26 is Compression, the elastic gasket 26 has a tendency to restore deformation and gives the nut 24 an outward thrust, so that the coupling nut 22, the elastic gasket 26 and the screw 24 becomes a whole, the cooperation of the nut 24 and the connecting nut 22 is not easily loosened. The screw 3 is screwed to the through hole 220 of the connecting nut 22 and connected to the supporting portion 14 of the body 1 , the freedom of the screw A clamping space β〇 is formed between the end and the abutting portion 1 2 of the body 10 for placing the object to be clamped. Please refer to FIG. 4 together, and now the combination of the heat absorbing plate 4〇 and the heat pipe 5〇 is For example, a method of using the clamping device 100 will be described. When the clamping device 1 is used, 'the heat absorbing plate 40 and the heat pipe 5 〇 are determined in a positional relationship and placed between the screw 3 〇 and the abutting portion 12 . The clamping space is 6 inches, and the heat pipe 5 is located below the connecting nut 22 to be the position of the perforating hole 22. The electric screwdriver (electric locking screw tool) is used to screw the screw 3 into the connecting nut 22 The perforation 22 is in the middle. Since the external thread of the bolt 34 of the screw 30 matches the internal thread of the coupling nut 22, the bolt 34 of the screw 3 can move through the through hole 220 of the coupling nut 22 toward the abutment 12 until The bolt 34 of the screw 30 abuts against the heat pipe 50. The electric screwdriver applies the screw 30 After a certain limit, the screw 30 squeezes the heat pipe 5 〇, and applies a pressure to the heat pipe 5 紧 to the heat absorbing plate 40. Since the length of the connecting nut 22 is long, the connecting nut 22 has a long guiding stroke to the screw 30' The coaxiality of the screw 30 and the connecting nut 22 is well preserved', thereby ensuring the perpendicularity of the screw 30 and the abutting portion 12, 099111530 Form No. Α01Ο1 Page 6 / Total 15 Page 0992020396-201135080 Screw 3G Respond to the vertical fairy on the heat (four) (four) to ensure the quality of the product. [0016] Ο [0018] In addition, since the electric screwdriver can provide a certain torque and the torque can be verified, the clamping force provided by the clamping device 100 can be kept consistent, and the same batch of products can be reduced. Quality differences. In addition, in the process of locking the screw, the screw 30 is pressed against the heat pipe 5Q, and a downward pressure is applied to the heat pipe 5 () while the heat pipe 50 reacts to the thrust of the screw 3Q_ upward, and the thrust has a selection portion. u is topped up, so that the distance between the branch portion 14 and the abutment portion 12 is slightly increased. The support portion 14 has a tendency to rebound toward the abutting portion 12. 34] During the welding process, gp slightly reduces the spacing between the heat pipe 5〇 and the heat absorbing plate 40, resulting in a decrease in the spacing between the screw 3〇 and the splicing portion 12, but the support portion 14 faces the abutment portion. The tendency of the 12 rebound causes the screw 30 to be held straight against the heat pipe 5 ,, providing a continuous and uniform clamping force for the heat pipe 5 〇 and the heat absorbing plate 40. In the clamping device 100, since the coupling nut 22 is fixed to the support portion 14 by the engagement with the nut 24, if the screw of the coupling nut 22 or the nut 24 is damaged due to long-term use, the connection can be directly made. The nut 22 and the nut 24 are loosened for repair or replacement, and the maintenance operation is convenient. In summary, the present invention complies with the requirements of the invention patent, and patents are filed according to law. However, the above description is only the preferred embodiment of the present invention, and equivalent modifications or variations made by those skilled in the art of the present invention should be included in the following claims.
