Description

Technical Field

[0001] The present disclosure relates to the field of CPU installation devices, and in particular to a CPU installation device. Background Art

[0002] The central processing unit (CPU) is the computing and control core of the computer system and the final execution unit for information processing and program running. The CPU connector is a connector component that mounts the CPU on the circuit board. The CPU connector generally includes a seat, a fixing plate and a rocker. The CPU is installed in the seat and electrically connected to the circuit board through the terminal. The rocker is used to press the fixing plate to fix the CPU between the seat and the fixing plate.

[0003] For example, Chinese patent application number CN200620133298.4 discloses a CPU electrical connector, comprising a base, on which a plurality of terminal slots arranged in a matrix and a support seat are provided, on which a pivot portion is provided; an upper cover, which is engaged with the base and can slide relative to the base, and on which a plurality of through holes arranged in a matrix and corresponding to the plurality of terminal slots of the base; a plurality of terminals, which are arranged in the plurality of terminal slots of the base; a rocker, which is provided with a rocking portion and a pivot portion, and the pivot portion is provided with at least a first axis and a second axis which are eccentric to each other, the first axis is pivotally connected to the pivot portion of the base, and the second axis is engaged with one end of the inner surface of the upper cover, the rocking portion is connected to the first axis and is provided with a handle, and when the rocker is pivoted, it drives the upper cover to slide relative to the base.

[0004] When installing the CPU, the upper cover of the CPU electrical connector is slid by the rocker so that the upper cover and the base are in an open state. At this time, the CPU is manually placed between the upper cover and the base, and the terminals are located in the base and electrically connected to the CPU. However, for CPUs with large weight and volume, interference will occur when the CPU is placed in the bottom shell manually, making it difficult to control the force when placing the CPU into the base. If the force exerted on the terminals when the CPU enters the base is large, it is easy to crush the terminals in the base, thereby causing damage to the entire connector. On the other hand, the terminals are not blocked by the shell, and dust can easily fall into the terminals, resulting in poor contact between the terminals and the CPU.

[0005] Therefore, there is an urgent need for a connector that can prevent terminals from being crushed when assembling a CPU. Utility Model Content

The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0032] The present disclosure provides a CPU installation device, comprising a mounting seat, a plurality of power connection posts, a support cover and a CPU connector, wherein the mounting seat is used to abut against a PCB board, the plurality of power connection posts are arranged in the mounting seat, and the plurality of power connection posts are electrically connected to the PCB board, the CPU installation device also comprises a support cover and a CPU connector, the mounting seat is provided with the support cover, the support cover is provided with a receiving groove, the receiving groove is used to accommodate the CPU, the CPU connector comprises a bottom sheet, a back connection fixing plate, a clamping sheet and an upper pressure installation fixing cover; the PCB board is clamped and connected between the bottom sheet and the back connection fixing plate; the back connection fixing plate is provided with an installation groove, the mounting seat is located in the installation groove and abuts against the PCB board; the clamping sheet is connected to a side of the upper pressure installation fixing cover close to the back connection fixing plate, and the upper pressure installation fixing cover is rotatably connected to the back connection fixing plate; the clamping sheet is clamped to the CPU at a side adjacent to the back connection fixing plate.

[0033] In the above-mentioned CPU installation device, the power connection post is installed in the installation seat and electrically connected to the PCB board, and the support cover is provided on the installation seat. When installing the CPU, the CPU is placed in the receiving groove on the support cover, and the upper pressure installation fixing cover is pressed down by rotating the upper pressure installation fixing cover, and the upper pressure installation fixing cover drives the clamping piece to be pressed down together, so that the clamping piece is clamped and connected to the CPU. At this time, the upper pressure installation fixing cover is rotated to rise, and the upper pressure installation fixing cover drives the CPU to rise together, and the support cover is removed from the installation seat. At this time, the upper pressure installation fixing cover is rotated again to press down to drive the CPU to be pressed down together, so that the CPU enters the installation seat and abuts against the power connection post, and the CPU assembly is completed.

[0034] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0035] like Figure 1 , Figure 2 , Figure 4, Figure 5 and Figure 6 As shown, a CPU installation device 10 of an embodiment includes a mounting seat 100 and a plurality of electrical terminals. The mounting seat 100 is used to abut against a PCB board 10a. The plurality of electrical terminals are arranged in the mounting seat 100, and the plurality of electrical terminals are electrically connected to the PCB board 10a. Further, the CPU installation device 10 also includes a support cover 200 and a CPU connector 300. The support cover 200 is arranged on the mounting seat 100. The support cover 200 is provided with a receiving groove 210. The receiving groove 210 is used to accommodate the CPU 10b. The CPU connector 300 includes a bottom film 350, a back connection fixing plate 310, a clamping plate 320 and an upper pressure installation fixing cover 330. The PCB board 10a is clamped and connected between the bottom film 350 and the back connection fixing plate 310. The back connection fixing plate 310 is provided with a mounting groove, the mounting seat 100 is located in the mounting groove and abuts against the PCB board 10a, the clamping piece 320 is connected to the side of the upper pressure mounting fixing cover 330 close to the back connection fixing plate 310, and the upper pressure mounting fixing cover 330 is rotatably connected to the back connection fixing plate 310; the clamping piece is clamped on the CPU at a side adjacent to the back connection fixing plate, so that when the upper pressure mounting fixing cover 330 rotates, the clamping piece 320 drives the CPU to rotate together.

[0036] It can be understood that since the size of the CPU cavity in the mounting seat 100 is adapted to the size of the CPU, so that the mounting seat 100 covers the CPU, for a CPU with a larger weight and volume, if traditional technology is used, that is, when the CPU is placed into the mounting seat 100 by hand, the surrounding walls of the mounting seat 100 interfere with the hands, and it is difficult to control the force when placing the CPU. If the force acting on the electrical terminals when the CPU enters the mounting seat 100 is large, it is easy to crush the electrical terminals in the mounting seat 100, causing damage to the entire connector.

[0037] In order to solve the above problems, in the present embodiment, the mounting base 100 and the back connection fixing plate 310 are pre-installed on the PCB board 10a, a plurality of electrical connection terminals are provided in the mounting base 100 and are electrically connected to the PCB board 10a, the mounting base 100 is located in the mounting groove of the back connection fixing plate 310, the top cover of the mounting base 100 is provided with a support cover 200, the clamping piece 320 is connected to the upper pressure mounting fixing cover 330, the upper pressure mounting fixing cover 330 is rotatably connected to the back connection fixing plate 310, and the clamping piece 320 is adjacent to one side of the back connection fixing plate 310 for clamping and connecting to the CPU. When installing the CPU, first place the CPU in the receiving groove 210 on the support cover 200, and then press the upper pressing installation fixing cover 330 downward by rotating, so that the upper pressing installation fixing cover 330 drives the clamping piece 320 downward together, so that the clamping piece 320 clamps and connects to the CPU, and then the upper pressing installation fixing cover 330 is rotated to rise, and the upper pressing installation fixing cover 330 drives the CPU upward together, and the support cover 200 is removed from the mounting seat 100, and then the upper pressing installation fixing cover 330 is rotated to press down again to drive the CPU downward together, so that the CPU enters the mounting seat 100 and abuts against the power connection post. Specifically, by driving the upper pressing installation fixing cover 330 to rotate and enter the mounting seat 100 and abut against the power connection post, the interference of the surrounding wall of the mounting seat 100 with the hands is avoided, and the force when the CPU abuts against the power connection post can be better controlled, thereby avoiding the problem of damage to the power connection post when assembling the CPU. Furthermore, the back connecting and fixing plate 310 is located at the top of the PCB board 10a, and the bottom film 350 is located at the bottom of the PCB board 10a. The PCB board 10a, the back connecting and fixing plate 310 and the bottom film 350 are locked by screws, so that the PCB board 10a is clamped and connected between the bottom film 350 and the back connecting and fixing plate 310, thereby improving the structural strength of the PCB board 10a to prevent the PCB board 10a from being crushed when the heavy CPU is pressed down.

[0038] In the CPU installation device 10, the power connection post is installed in the installation seat 100 and electrically connected to the PCB board 10a, and the support cover 200 is covered on the installation seat 100. When installing the CPU, the CPU is placed in the receiving groove 210 on the support cover 200, and the upper pressing installation fixing cover 330 is rotated to press down, and the upper pressing installation fixing cover 330 drives the clamping piece 320 to press down together, so that the clamping piece 320 clamps and clamps the CPU, and then the upper pressing installation fixing cover 330 is rotated to rise, and the upper pressing installation fixing cover 330 drives the CPU to rise together, and the support cover 200 is removed from the installation seat 100, and then the upper pressing installation fixing cover 330 is rotated to press down again, so as to drive the CPU to press down together, so that the CPU enters the installation seat 100 and abuts against the power connection post, and the CPU assembly is completed. Specifically, by providing a support cover 200 on the mounting seat 100, the CPU can be driven into the mounting seat 100 by rotating and pressing the mounting fixing cover 330 when the CPU is assembled, thereby avoiding interference caused by the base when the CPU is placed manually, and thus better controlling the force generated by the docking electrical terminals when the CPU enters the mounting seat 100, thereby avoiding damage to the electrical terminals due to large forces.

[0039] like Figure 2 As shown, in one embodiment, the CPU connector 300 further includes a mounting connection center axis 340 and a connection fixing base 311, the connection fixing base 311 is convexly arranged on the back connection fixing plate 310, the connection fixing base 311 is provided with a first rotation through hole, the upper pressing mounting fixing cover 330 is provided with a second rotation through hole, and parts of the mounting connection center axis 340 are respectively penetrated in the first rotation through hole and the second rotation through hole, so that the upper pressing mounting fixing cover rotates relative to the back connection fixing plate 310 with the mounting connection center axis as the center. It can be understood that the number of the connection fixing bases 311 is two, and the two connection fixing bases 311 are arranged oppositely, the two ends of the mounting connection center axis 340 are located in the two first rotation through holes, and the two ends of the mounting connection center axis 340 are respectively fixedly connected to the two connection fixing bases 311, and the middle part of the mounting connection center axis 340 passes through the second rotation through hole of the upper pressing mounting fixing cover 330, so that the upper pressing mounting fixing cover 330 rotates relative to the mounting connection center axis 340.

[0040] like Figure 2 and Figure 6As shown, in one embodiment, the back of the clamping sheet 320 is connected to the fixing plate and is provided with a clamping and clamping column 321. The clamping and clamping column 321 is located on a side of the clamping sheet 320 adjacent to the back connecting fixing plate 310. The number of the clamping and clamping columns 321 is at least two, and the clamping and clamping columns 321 are used to clamp and clamp the CPU. It can be understood that the two clamping and clamping columns 321 are respectively arranged on both sides of the clamping sheet 320, so that when the clamping sheet 320 is pressed down, the two clamping and clamping columns 321 clamp and clamp the CPU under the action of external force. Furthermore, the number of the clamping and clamping columns 321 can be multiple, that is, the multiple clamping and clamping columns 321 are evenly distributed along the periphery of the clamping sheet 320, so as to achieve a better clamping effect on the CPU.

[0041] like Figure 3 and Figure 5 As shown, in one embodiment, the periphery of the support cover 200 is provided with a avoidance opening 220 connected to the receiving groove 210, and the clamping and clamping column 321 passes through the avoidance opening 220 when pressed down. In this embodiment, the avoidance opening 220 is used to avoid the clamping and clamping column 321, so as to prevent the support cover 200 from interfering with the clamping and clamping column 321 when the clamping and clamping column 321 is pressed down to clamp and clamp the CPU.

[0042] like Figure 6 As shown, in one embodiment, the clamping clamping column 321 includes a clamping body 321a and a clamping clamping protrusion 321b connected to each other, and the clamping clamping protrusion 321b is located on the inner side of the clamping body 321a. In this embodiment, the clamping body 321a and the clamping clamping protrusion 321b are an integrally formed structure, and the clamping clamping protrusion 321b is convexly arranged on the inner side of the clamping body 321a adjacent to the CPU. When the clamping sheet 320 is pressed down and abuts against the CPU, the clamping clamping protrusion 321b is deformed by the pressure, so that the clamping clamping protrusion 321b is clamped into the surface of the CPU.

[0043] like Figure 5As shown, in one embodiment, the support cover 200 is provided with a positioning column 230 on the upper pressing and mounting fixing cover, and the positioning column 230 is located on a side of the support cover 200 adjacent to the upper pressing and mounting fixing cover 330, the clamping sheet 320 is provided with a first guide hole 322, and the upper pressing and mounting fixing cover 330 is provided with a second guide hole 331 corresponding to the first guide hole 322, and the positioning column 230 is used to pass through the first guide hole 322 and the second guide hole 331 in sequence when the upper pressing and mounting fixing cover 330 is close to the back connecting and fixing plate 310. It can be understood that when the upper pressing and mounting fixing cover 330 drives the clamping sheet 320 to rotate toward the back connecting and fixing plate 310, the positioning column 230 passes through the first guide hole 322 and the second guide hole 331 in sequence, and the positioning column 230 plays a positioning and guiding role, so that the clamping sheet 320 is clamped and connected to the CPU more accurately. Furthermore, there are multiple positioning posts 230 , multiple first guide holes 322 and multiple second guide holes 331 , and each positioning post 230 is provided with a corresponding first guide hole 322 and a corresponding second guide hole 331 .

[0044] like Figure 6 As shown, in one of the embodiments, a deformable connecting hook 323 is protruded from a side of the clamping piece 320 adjacent to the upper pressing installation fixing cover 330, and the upper pressing installation fixing cover 330 is provided with a snap-in connecting through hole 332, and the deformable connecting hook 323 is passed through the snap-in connecting through hole 332, and the clamping piece 320 is snap-connected with the upper pressing installation fixing cover 330 through the deformable connecting hook 323. In this embodiment, the deformable connecting hook 323 includes a first elastic clamping column 323a and a second elastic clamping column 323b arranged adjacent to each other, and the first elastic clamping column 323a and the second elastic clamping column 323b are both fixedly connected to the clamping sheet 320, and the first elastic clamping column 323a and the second elastic clamping column 323b respectively pass through the clamping connection through hole 332 and are clamped with the upper pressing installation fixing cover 330, so that the clamping sheet 320 is fixed to the upper pressing installation fixing cover 330, and then the upper pressing installation fixing cover 330 rotates together with the clamping sheet 320. Further, the number of the deformable connecting hooks 323 is multiple, the number of the clamping connection through hole 332 is also multiple, and the multiple deformable connecting hooks 323 are evenly distributed along the periphery of the clamping sheet 320, so that the fixing effect of the clamping sheet 320 and the upper pressing installation fixing cover 330 is better.

[0045] like Figure 3As shown, it should be noted that, since the clamping sheet 320 is clamped with the upper pressing and mounting fixing cover 330 through the deformable connecting hook 323, in another embodiment, when assembling the CPU, the clamping sheet 320 can be first removed from the upper pressing and mounting fixing cover 330; then, the clamping sheet 320 is clamped and buckled with the CPU, that is, the clamping sheet 320 clamps the CPU through the clamping clamping column 321; then, the assembly after the clamping sheet 320 and the CPU are clamped is placed in the receiving groove 210 of the support cover 200, and at this time, the upper pressing and mounting fixing cover 330 is rotated toward the support cover 200, so that the clamping sheet 320 is clamped and buckled. The deformable connecting hook 323 of 20 passes through the locking connecting through hole 332 of the upper pressing installation fixing cover 330, so that the clamping piece 320 is locked with the upper pressing installation fixing cover 330; then, the upper pressing installation fixing cover 330, the clamping piece 320 and the CPU are rotated together in the direction away from the back connection fixing plate 310, and the support cover 200 is removed from the mounting seat 100 at this time; finally, the upper pressing installation fixing cover 330, the clamping piece 320 and the CPU are rotated together in the direction close to the back connection fixing plate 310, so that the CPU abuts against the power connection terminal in the mounting seat 100 to complete the assembly.

[0046] like Figure 3 As shown, in one embodiment, the CPU installation device 10 further includes a locking member 400, the upper pressing installation fixing cover 330 is provided with a first locking hole, the back connecting fixing plate 310 is provided with a second locking hole corresponding to the first locking hole, and the locking member 400 is sequentially inserted into the first locking hole and the second locking hole. It can be understood that when the upper pressing installation fixing cover 330 presses the CPU into the mounting seat 100 and the CPU abuts against the power connection terminal, the upper pressing installation fixing cover 330 and the back connecting fixing plate 310 are locked by the locking member 400, so that the upper pressing installation fixing cover 330 and the back connecting fixing plate 310 are fixed, and at the same time, the CPU is in close contact with the power connection terminal. In this embodiment, the locking member 400 is a screw.

[0047] like Figure 5 As shown, in one embodiment, the periphery of the support cover 200 is provided with a grabbing protrusion 240, and the grabbing protrusion 240 is provided with a grabbing groove 241. In this embodiment, there are two grabbing protrusions 240, which are respectively distributed on both sides of the support cover 200. When the clamping sheet 320 clamps and connects the CPU, the support cover 200 needs to be removed from the top of the mounting seat 100, and the grabbing groove 241 in the grabbing protrusion 240 is grasped, so that the support cover 200 can be taken and placed more conveniently.

[0048] Compared with the prior art, the present invention has at least the following advantages:

[0049] In the CPU installation device 10, the power connection post is installed in the installation seat 100 and electrically connected to the PCB board 10a, and the support cover 200 is covered on the installation seat 100. When installing the CPU, the CPU is placed in the receiving groove 210 on the support cover 200, and the upper pressing installation fixing cover 330 is rotated to press down, and the upper pressing installation fixing cover 330 drives the clamping piece 320 to press down together, so that the clamping piece 320 clamps and clamps the CPU, and then the upper pressing installation fixing cover 330 is rotated to rise, and the upper pressing installation fixing cover 330 drives the CPU to rise together, and the support cover 200 is removed from the installation seat 100, and then the upper pressing installation fixing cover 330 is rotated to press down again, so as to drive the CPU to press down together, so that the CPU enters the installation seat 100 and abuts against the power connection post, and the CPU assembly is completed. Specifically, by providing a support cover 200 on the mounting seat 100, the CPU can be driven into the mounting seat 100 by rotating and pressing the mounting fixing cover 330 when the CPU is assembled, thereby avoiding interference caused by the base when the CPU is placed manually, and thus better controlling the force generated by the docking electrical terminals when the CPU enters the mounting seat 100, thereby avoiding damage to the electrical terminals due to large forces.

[0050] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the patent of the present disclosure shall be based on the attached claims.
