Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a coupling device, and more particularly, to a heat-radiating-part coupling device in which a hook of a lower retaining part is hidden in a cartridge cover to prevent it from being easily detached when a fastener is combined with a cartridge.

[0002]

[Prior art]

 Pentium II (PENTIUM II) is provided with a CPU (CENTRAL PROCESSING UNIT) and an external cache memory (EXTERNAL CACHE) on a circuit board, and is packaged in PLGA (PLASTIC LAND-GRID ARRAY). At the same time, it is connected to the motherboard by the method of cartridge gold finger connection. However, the PLGA packaging process of the CPU is cumbersome and takes a lot of time to manufacture. In addition, this type of packaging increases the price of the CPU and cannot increase price competitiveness and market share. Therefore, a circuit board type CPU without PLGA packaging was developed, but it cannot be combined with the current CPU because the thickness is not so thin as PLGA packaging. Also, there are no suitable coupling devices and heat dissipation parts. Therefore, in order to reduce cost and manufacturing time, an electric circuit type CPU structure combining an electric circuit type CPU and a heat radiating part is required.

[0002]

[Problems to be solved by the invention]

 In order to reduce cost and manufacturing time, an electric circuit type CPU structure combining an electric circuit type CPU and a heat radiating part is provided. Also, when the cartridge is assembled with the fastener, the claws of the lower retaining parts are hidden inside the cartridge to prevent it from being easily removed.

[0004]

[Means for Solving the Problems]

 A fastener is constructed by combining the main body and the upper clasp parts, and a concave portion is provided at an appropriate position on the main body so that both ends of the clasp have elasticity. One end is bent to form a clasp part, and the end of the clasp part is bent to provide a nail having an appropriate inclination angle. A fixing hole is provided at an appropriate position on the main body, and it is used to combine the upper clasp parts. A flat push portion is provided at the end of the top fastening part, and a concave tank and a hook hole are provided at an appropriate position of the top fastening part. When assembling, hook the above-mentioned holes into the protrusions on the upper part of the cartridge, and pass the retaining parts through the through holes opened in the heat radiation parts, the CPU circuit board, and the cartridge. The heat dissipating parts are brought into close contact with the CPU surface, and the cartridge is provided with through holes corresponding to the angles of the claws and concave fitting parts, so that the claws are hidden in the cartridge and the fasteners do not deform and come off.

[0005]

[Embodiment of the invention]

 As shown in FIGS. 1 and 2, a fastener 10 is formed by combining a main body 11 and an upper fastening part 12, and a concave portion 111 is provided at an appropriate position of the main body 11 so that both ends of the fastener 10 have elasticity. One end is bent to form a retaining part 112, and the end of the retaining part 112 is bent to provide a tab 113 having an appropriate inclination angle. The fixing hole 114 at an appropriate position in the main body 11 is used for assembling the upper clasp part 12. A flat push part 121 is provided at the end of the upper retaining part 12, and a concave tank 122 and a hook hole 123 of the main body 11 are provided at appropriate positions.

As shown in FIGS. 2 and 3, there is a space in the cartridge 20 for installing the CPU circuit board 30, a convex portion 21 is provided at the center thereof, and a convex point 211 is provided above the convex portion 21. There is. Further, a localization part 22 having a through hole 221 is provided. The through hole 221 below the cartridge 20 corresponds to the angle of the nail 113 and the fitting part 222 of the cartridge 20 described above. Further, a projection 23 is provided on the upper portion of the cartridge 20 in accordance with the position of the localization part 22. Elastic parts 24 are provided on both sides of the cartridge 20, and the elastic parts 24 have hooks 241 at appropriate positions. When the cartridge 20 is combined with the CPU, the hook 241 can be combined or removed using the elasticity of the elastic part 24 (this is the same as the conventional combination, so it is omitted in the drawing). A pull part 242 is provided on the upper part of the elastic part 24, and a hanging part 243 is provided on a bottom edge of the pull part 242. A pinch groove 25 is provided in the upper portion of the cartridge 20, and the elastic part 24 presses the hanging part 243 against the pinch groove 25 to fix the position of the elastic part 24 for convenient removal. The golden fingers 31 are provided below the CPU circuit board 30 and inserted into the motherboard. A through hole 221 is provided in the localization part 22 at the same position as the hole 33. The CPU circuit board 30 is sandwiched inside the sandwiching plate 40 to correspond to the cartridge 20. The upper part is sealed by the upper frame 41, and the side and the bottom are sealed by the horizontal frame 42 and the cover board 43. In this manner, it is sandwiched between the upper frame 41, the horizontal frame 42, and the cover board 43, and is fitted around the CPU circuit board 30. The CPU circuit board 30 can be laid flat inside the cartridge 20, and the cover board 43 forms a space for installing the golden fingers 31 corresponding to the cartridge 20. The overall appearance is similar to a PLGA package.

The heat dissipating part 50 has a mounting position 51 without splash, and a through hole 52 is provided in the localization part 22 opposite to the mounting position 51. When assembling the fastener 10 integrally, the assembling method inserts the upper clasp part 12 into the fixing hole 114 and fixes the concave tank 122 of the upper clasp part 12 to the fixing hole 114. By pressing the upper clasp part 12, it can be moved by the axis. A fixing hole 114 is provided at an appropriate position on the main body 11, and a round hole 115 is formed at an end. When the upper retaining part 12 is inserted into the fixing hole 114, the fixing hole 114 returns to its original shape due to the elastic recovery force and does not deform. Then, the main body 11 is inserted into the mounting position 51 of the heat dissipating part 50 where there is no splash, and the retaining part 112 is inserted into the through hole 52 of the mounting position 51 and the hole 33 of the CPU circuit board 30, and the through hole 221 of the cartridge 20 is inserted. Hook into the fitting part 222 and combine. Push the push part 121 above the upper retaining part 12, and hook the hook hole 123 over the projection 23 above the cartridge 20. As described above, the concave portion 111 serves as a fulcrum, and the hooks 123 and the claws 113 at both ends are hooked on the cartridge 20 to form a pressing force. The force generates a repulsive force at both ends of the fastener, and the main body 11 presses down the heat radiating part 50 and tightly couples the heat radiating part 50 and the CPU chip 32 to achieve the purpose of heat radiation.

[0005] The above-mentioned claw 113 is inclined at an appropriate angle so as to have strength against a pulling force. The fitting angle 222 corresponds to the angle of inclination, and when hooked, it is stably fixed at the position of the claw 113 so that a phenomenon of deformation or detachment does not occur. Since the fitting portion 222 is in the cover of the cartridge 20, the tab 113 is hidden in the cartridge after assembly. Therefore, the motherboard and other parts do not touch the claws 113, and the combination is secure and cannot be easily removed.

[0006]

[Effect of the invention]

 Since the claws 113 have an inclination at an appropriate angle and have strength against the pulling force, and the fitting angle 222 corresponds to the inclination angle, the claws 113 are stably fixed and do not deform or come off. Further, since the fitting portion 222 is in the cartridge 20, after the assembly, the tab 113 is hidden in the cartridge, and the motherboard and other parts do not touch the tab 113, so that the fixing is more reliable.
