[0035] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] This embodiment provides a fixed structure for a CPU, such as... Figures 1-3 As shown, the fixing structure includes a base 1, a cover plate 2, and a fixing component 3. The base 1 supports the CPU 100, the cover plate 2 covers the base 1, and the fixing component 3 is configured to fix the base 1 and the cover plate 2 to secure the CPU 100 to the base 1. The base 1 is provided with a socket, and the CPU 100 is provided with multiple pins. The multiple pins are plugged into the socket to ensure the connection between the CPU 100 and the base 1.

[0037] In this embodiment, the base 1 is the motherboard, the CPU 100 is mounted on the motherboard socket, the cover plate 2 can cover the socket, and the fixing component 3 includes a plurality of fixing members 31, which pass through the cover plate 2 and are connected to the base 1.

[0038] To ensure reliable connection between the CPU 100's pins and the motherboard's socket, the pins and socket are in a spring-loaded contact. The cover plate 2 is secured to the motherboard by multiple fasteners 31. When the first fastener 31 is installed or the last fastener 31 is removed, the side of the cover plate 2 opposite to that fastener 31 will be lifted by the CPU 100, causing the CPU 100 to tilt. This can easily lead to displacement of the CPU 100 and damage to the pins or socket.

[0039] like Figure 3 and Figure 4To solve the above problems, the base 1 is provided with a limiting column 11, which is arranged through the cover plate 2 to limit the distance between the cover plate 2 and the base 1.

[0040] When the cover plate 2 is arranged on the base 1, the limiting column 11 needs to be arranged through the cover plate 2 to limit the cover plate 2, at this time, the cover plate 2 at the position of the limiting column 11 will not be lifted, and the operator can first fix the cover plate 2 relative to the opposite side of the limiting column 11 with the base 1 by using the fixing assembly 3, and then fix other positions of the cover plate 2, or first disassemble other positions of the cover plate 2, and then disassemble the opposite side of the cover plate 2 relative to the limiting column 11.

[0041] The fixing structure of the CPU can avoid the CPU 100 from being tilted and lifted, protect the pins of the CPU 100 and the sockets of the mainboard, and avoid damage.

[0042] The opposite side is determined relative to the center of the cover plate 2, in the embodiment, the cover plate 2 is rectangular, so the center of the cover plate 2 is the intersection of the two diagonal lines of the rectangle, if the fixing member 31 closest to the limiting column 11 is located at the corner of the rectangle, the fixing member 31 at the diagonal position of the corner is preferentially installed or disassembled, if the fixing member 31 closest to the limiting column 11 is located at one side of the rectangle, the fixing member 31 at the opposite side of the side is preferentially installed or disassembled. In some embodiments, the cover plate 2 is of other shapes, such as circular, hexagonal, etc., and the disassembly sequence is similar, which will not be described here.

[0043] In the embodiment, the plurality of fixing members 31 are arranged at intervals along the circumference of the cover plate 2, the distance between the limiting column 11 and one of the fixing members 31 is less than the distance between the limiting column 11 and any other fixing member 31. The plurality of fixing members 31 can fix the cover plate 2 from the outer circumference, ensure that the cover plate 2 is parallel to the base 1, and thus make the CPU 100 balanced. The limiting column 11 is arranged beside one of the fixing members 31, that is, the limiting column 11 can temporarily replace the fixing member 31 to fix the cover plate 2, when the cover plate 2 needs to be disassembled or installed, the fixing member 31 closest to the limiting column 11 needs to be preferentially disassembled or the fixing member 31 closest to the limiting column 11 needs to be finally installed.

[0044] As Figure 1 and Figure 3As shown, in order to prevent the cover plate 2 from crushing the CPU 100, the fixing assembly 3 further comprises an elastic piece 32 corresponding to each fixing piece 31, the fixing piece 31 has a cap body 311 at the end away from the base 1, the elastic piece 32 abuts against the cap body 311 at one end, and abuts against the cover plate 2 at the other end, so that the cover plate 2 elastically abuts against the CPU 100. The elastic piece 32 can not only press the cover plate 2 against the CPU 100, but also ensure that the pressure of the cover plate 2 on the CPU 100 gradually increases during the installation process, thereby effectively protecting the CPU 100 and avoiding being crushed.

[0045] In the embodiment, the base 1 is provided with a second connecting column 13 corresponding to each fixing piece 31, and the fixing piece 31 is sleeved on and screwed with the corresponding second connecting column 13. The fixing piece 31 can gradually compress the elastic piece 32 during rotation, which can not only press the cover plate 2, but also reduce the increasing speed of the pressure of the cover plate 2 on the CPU 100, thereby further reducing the possibility of the CPU 100 being crushed.

[0046] Generally, the CPU 100 generates heat during work. In order to ensure that the working temperature of the CPU 100 is within a proper range, the fixing structure further comprises a heat sink, which is arranged on the side of the cover plate 2 away from the base 1 and is in heat exchange connection with the cover plate 2.

[0047] The cover plate 2 is preferably made of a material with good thermal conductivity, so that the cover plate 2 can act as a bridge for heat exchange between the heat sink and the CPU 100, and ensure that the heat sink can effectively dissipate heat from the CPU 100. Specifically, the cover plate 2 is made of a metal material, such as copper, aluminum, etc. In some embodiments, the cover plate 2 can also be a uniform temperature plate, which can more efficiently transfer heat and also ensure that the temperature difference of the CPU 100 is not too large.

[0048] In the embodiment, in order to avoid the limiting column 11 affecting the installation of the CPU 100, the limiting column 11 is arranged beside the socket, the area of the cover plate 2 is greater than that of the CPU 100, and in the direction perpendicular to the base 1, the projection of the cover plate 2 on the base 1 can cover the projection of the CPU 100 on the base 1, so that the cover plate 2 can press the CPU 100, and the cover plate 2 and the CPU 100 are in surface contact, thereby ensuring that the CPU 100 is uniformly stressed.

[0049] As Figure 3 and Figure 4As shown, the limiting column 11 comprises a positioning column 111 and a limiting portion 112 protruding from the sidewall of the positioning column 111, the positioning column 111 penetrates the cover plate 2, and the limiting portion 112 abuts against the side of the cover plate 2 away from the base 1. The limiting portion 112 can limit the distance between the cover plate 2 and the base 1 at the position of the limiting column 11, preventing the cover plate 2 from tilting and causing the CPU 100 to tilt. The positioning column 111 can limit the cover plate 2 in the direction parallel to the base 1, thereby positioning the cover plate 2 and preventing the CPU 100 from translating the cover plate 2 and causing the CPU 100 to shift, ensuring the accuracy of the position of the cover plate 2.

[0050] In order to position the cover plate 2 together with the positioning column 111, the base 1 is further provided with a positioning pin 14, which penetrates the cover plate 2 and limits the cover plate 2 in the direction parallel to the base 1. By positioning the cover plate 2 together with the positioning pin 14 and the positioning column 111 of the limiting column 11, the accuracy of the position of the cover plate 2 can be greatly improved, and the cover plate 2 can be prevented from shifting and rotating.

[0051] It is worth noting that the limiting portion 112 is annular, and when the limiting column 11 penetrates the cover plate 2, it will cause extrusion between the limiting portion 112 and the cover plate 2. If the limiting portion 112 is worn, it will not be able to effectively limit the cover plate 2. To solve the above problem, the positioning column 111 comprises at least two column bodies 1111 arranged at intervals, and the sidewalls of the at least two column bodies 1111 are provided with limiting portions 112. When the limiting column 11 penetrates or exits the cover plate 2, the two column bodies 1111 can be clamped to reduce the distance between the limiting portions 112 of the two column bodies 1111, so that the limiting column 11 can penetrate the cover plate 2, avoiding extrusion between the limiting portion 112 and the cover plate 2.

[0052] In this embodiment, when the cover plate 2 abuts against the limiting portion 112, the distance between the cover plate 2 and the base 1 is L1, and when the fixing assembly 3 fixes the cover plate 2 and the base 1, the distance between the cover plate 2 and the base 1 is L2, L1 is greater than or equal to L2. That is, the limiting effect of the limiting column 11 on the cover plate 2 is only to prevent the cover plate 2 from being too far away from the base 1, at this time the pressing force of the cover plate 2 on the CPU 100 is smaller, and when the fixing assembly 3 fixes the cover plate 2 and the base 1, the limiting column 11 does not limit the cover plate 2, thereby reducing the load borne by the limiting portion 112 and improving the service life.

[0053] As shown in Figure 2 and Figure 3 The base 1 is provided with a first connecting column 12, and the limiting column 11 is provided with a connecting groove, and the first connecting column 12 is connected with the limiting column 11 through the connecting groove. The first connecting column 12 fixes the limiting column 11, thereby ensuring that the limiting column 11 can limit the cover plate 2.

[0054] It is worth mentioning that the first connecting column 12 and the connecting groove can be in interference fit or threaded connection.

[0055] The above is only the preferred embodiment of the present application, and for those skilled in the art, according to the idea of the present application, the specific implementation and application range can be changed, and the content of the specification should not be understood as limiting the present application.
