Description

Technical Field

[0001] This application relates to the field of heat dissipation technology, and more particularly to a fan and electronic device. Prior Technology

[0002] With the rapid development of electronic technology, electronic components are becoming increasingly high-performance and high-speed. This leads to a surge in the heat generated by these components. To dissipate this heat, the industry typically installs fans in electronic devices to cool the components. A fan usually consists of a fan frame, internal components housed within the fan frame, and conductive wires connecting the internal components to external circuitry. A common arrangement of the conductive wires is as follows: first, a bracket is installed on the fan frame; then, the wires are mounted on the bracket; finally, a fixing component holds the wires in place, fixing the conductive wires to the terminal block in the same area, enabling quick plugging and unplugging of the fan.

[0003] However, the above arrangement requires the use of bracket components and multiple fixing components to fix the position of the conductive wires. The components occupy a large space, the heat dissipation space of the electronic device is reduced, the heat exchange efficiency is reduced, and the computing load of the heat dissipation system is increased. In addition, the difficulty of fan assembly is increased, and the production cost is increased. Summary of the Invention

[0004] In view of this, in order to solve at least one of the above technical problems, this application provides a fan and an electronic device.

[0005] In a first aspect, this application provides a fan, including a fan frame, a plurality of wires, a terminal plate, and a limiting assembly. A first end of each wire extends into the interior of the fan frame, and a second end of each wire extends into the exterior of the fan frame. The fan frame includes a mounting area, which is provided with a first limiting member, a first mounting plate, and a second mounting plate. The first mounting plate and the second mounting plate are disposed opposite each other along a second direction, and are respectively located on both sides of the first limiting member along the first direction. The first limiting member has a first limiting hole extending along the first direction. The first mounting plate and the second mounting plate are respectively provided with mounting grooves that extend along the second direction; the terminal plate is movably inserted into the mounting groove; the terminal plate is provided with a second limiting hole extending along the thickness direction of the terminal plate and a plurality of cable routing holes, the first limiting hole and the second limiting hole coincide along the axis of the first direction; the cable routing holes are configured to connect the second end of the wire; the limiting component is configured to connect the first limiting hole and the second limiting hole, and the inner diameter of the second limiting hole is larger than at least part of the diameter of the limiting component, so that the terminal plate is floatingly connected to the mounting groove.

[0006] The fan's terminal block has cable routing holes, allowing wires to be connected to the terminal block. The fan frame's mounting area has a mounting groove, allowing the terminal block to be movably inserted into it, ensuring the wires and terminal block are in the same area on the fan frame. A limiting component connects the first and second limiting holes, confining the terminal block within the mounting groove. Furthermore, the inner diameter of the second limiting hole is larger than the diameter of at least part of the limiting component, enabling floating installation of the terminal block within the mounting groove and reducing the impact of vibration on the connection stability between the connector and the terminal block. The cable routing holes eliminate the need for additional components for wire fixing and installation, simplifying fan assembly, ensuring sufficient internal heat dissipation space for electronic devices, improving heat exchange efficiency, and reducing the computational load on the cooling system.

[0007] In some embodiments, the limiting component includes an expansion member and a first positioning pin. The expansion member passes through the first limiting hole and has an expansion hole. The second limiting hole and the expansion hole coincide along the axis of the first direction. The first positioning pin includes a first limiting portion and a pin body. The first limiting portion abuts against the surface of the first limiting member away from the installation area. The pin body is configured to pass through the expansion hole and the first limiting hole, and at least a portion of the expansion member is configured to expand and deform in a direction perpendicular to the axis of the expansion hole.

[0008] The first positioning pin passes through the second limiting hole and the expansion hole. Through the cooperation of the mounting groove and the first positioning pin, the terminal block can be floated in the mounting groove. After the first positioning pin passes through the expansion member and deforms, its diameter is larger than the diameter of the first limiting hole, which can ensure that the first positioning pin will not come out of the first limiting hole, thereby ensuring the stable installation of the terminal block in the mounting groove during operation.

[0009] In some embodiments, the first limiting hole includes a first hole segment and a second hole segment, the second hole segment is disposed at the end of the first hole segment away from the installation area, and the diameter of the second hole segment is larger than the diameter of the first hole segment; the expansion member includes an expansion body and a second limiting part, the diameter of the second limiting part is larger than the inner diameter of the first hole segment, the expansion body passes through the first hole segment, the second limiting part is received in the second hole segment, and the second limiting part is not protruding from the surface of the first limiting member.

[0010] The second limiting part does not protrude from the surface of the first limiting part, which improves the aesthetics and reduces the impact of other parts on the limiting component, ensuring the stable installation of the limiting component.

[0011] In some embodiments, the limiting component includes a positioning body and a second positioning pin. At least a portion of the positioning body is embedded in the first limiting hole. The positioning body has a first positioning post, which is configured to connect the first limiting hole and the second limiting hole. The positioning body has a first positioning hole, and the top of the first limiting component along a third direction has a second positioning hole. The first positioning hole and the second positioning hole coincide along the axis of the third direction. The second positioning pin is configured to connect the first positioning hole and the second positioning hole, thereby fixing the limiting component to the first limiting hole.

[0012] The positioning body is fixed in the first limiting hole by the second positioning pin. The limiting component occupies little system space, which can further increase the heat dissipation space inside the electronic device.

[0013] In some embodiments, the limiting component includes a limiting plate and a snap-fit ​​arm. The limiting plate is located on the side of the first limiting member away from the mounting area. The limiting plate is provided with a second positioning post. The snap-fit ​​arm extends from the wall of the limiting plate toward the mounting area, and the end of the snap-fit ​​arm away from the limiting plate is provided with a snap-fit ​​portion. The limiting plate is configured to connect the first limiting hole and the second limiting hole via the second positioning post, and the snap-fit ​​portion snaps into the first mounting plate and the second mounting plate.

[0014] After the second positioning post connects the third limiting hole, the first limiting hole and the second limiting hole, it can prevent the terminal plate from disengaging from the limiting groove. Furthermore, the snap-fit ​​part of the snap-fit ​​arm can prevent the limiting protrusion from disengaging from the first limiting hole by snapping with the first mounting plate and the second mounting plate, thus ensuring the stable installation of the terminal groove.

[0015] In some embodiments, the snap-fit ​​arm includes a first extension arm and a second extension arm connected to each other. The second extension arm is bent from the end of the first extension arm away from the limiting plate toward the mounting area. The first mounting plate and the second mounting plate are provided with snap-fit ​​grooves on their sidewalls near the first limiting member. The limiting plate is configured to be mounted on the side of the first limiting member away from the mounting area by means of the second positioning post, and at least a portion of the first extension arm is received in the snap-fit ​​groove. The snap-fit ​​portion snaps into the first mounting plate and the second mounting plate.

[0016] The snap-fit ​​grooves provided on the first mounting plate and the second mounting plate, with at least a portion of the first extension arm housed in the snap-fit ​​grooves, can reduce the distance between the limiting plate and the terminal plate after the limiting component is installed, thereby reducing the system space occupied by the limiting component.

[0017] In some embodiments, the installation area is provided with a second limiting member, which is disposed opposite to the first limiting member along a first direction, and the second limiting member is provided with a third limiting hole that passes through along the first direction. The first limiting hole, the second limiting hole and the third limiting hole coincide along the axis of the first direction, and the limiting member is configured to connect the first limiting hole, the second limiting hole and the third limiting hole.

[0018] By setting the second limiting member, the movement of the end of the limiting component away from the first limiting member can be restricted, thereby improving the installation stability of the limiting component.

[0019] In some embodiments, the fan further includes a shock absorber disposed within the mounting groove and located between the surface of the terminal block and the wall of the mounting groove.

[0020] The fan will generate a certain amount of vibration during operation. This vibration is transmitted to the terminal plate through the contact between the mounting slot and the terminal plate, which will affect the connection stability between the terminal plate and the connector. By installing a shock absorber between the surface of the terminal plate and the wall of the mounting slot, the impact of fan vibration on the connection stability between the terminal plate and the connector can be further reduced.

[0021] In some embodiments, the terminal block is provided with electrical contact areas distributed on two surfaces of the terminal block, and at least some of the electrical contact areas have different areas.

[0022] The electrical contact area is used for electrical connection with the connector. The electrical contact areas are distributed on both sides of the terminal block and have different areas, which can provide more contact surface and help ensure a more stable electrical connection. In a vibrating environment, the large contacts can reduce the risk of open circuit due to poor contact and improve the reliability and durability of the fan.

Implementation

[0025] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0026] Example 1

[0027] With the rapid development of electronic technology, electronic components are becoming increasingly high-performance and high-speed. This leads to a surge in the heat generated by these components. To dissipate this heat, the industry typically installs fans in electronic devices. A fan usually consists of a fan frame, internal components housed within the fan frame, and conductive wires connecting the internal components to external circuitry. The conventional arrangement of the conductive wires involves first mounting a bracket on the fan frame, then attaching the wires to the bracket, and finally securing the wires with fixing components, thus fixing the conductive wires to the terminal block in the same area for quick fan insertion and removal. However, this arrangement requires brackets and multiple fixing components to secure the conductive wires, resulting in large space occupied by these components, reduced heat dissipation space in the electronic device, decreased heat exchange efficiency, and increased computational load on the cooling system. Furthermore, it increases the difficulty of fan assembly and raises production costs.

[0028] Therefore, referring to Figures 1-5, this application provides a fan 10, including a fan frame 1, a plurality of wires 2, a terminal plate 3, and a limiting component 4. The first end of the wire 2 extends into the interior of the fan frame 1, and the second end of the wire 2 extends into the exterior of the fan frame 1. The fan frame 1 includes a mounting area 11, which is provided with a first limiting member 13, a first mounting plate 14, and a second mounting plate 15. The first mounting plate 14 and the second mounting plate 15 are arranged opposite each other along the second direction Y, and the first mounting plate 14 and the second mounting plate 15 are respectively located on both sides of the first limiting member 13 along the first direction X. The first limiting member 13 is provided with a first... The first mounting plate 14 and the second mounting plate 15 are respectively provided with mounting grooves 141 that extend along the second direction Y. The terminal plate 3 is movably inserted into the mounting groove 141. The terminal plate 3 is provided with a second limiting hole 31 extending along the thickness direction of the terminal plate 3 and a plurality of cable routing holes 32. The first limiting hole 131 and the second limiting hole 31 coincide along the axis of the first direction X. The cable routing holes 32 are configured to connect the second end of the wire 2. The limiting component 4 is configured to connect the first limiting hole 131 and the second limiting hole 31, and the inner diameter of the second limiting hole 31 is larger than at least part of the diameter of the limiting component 4, so that the terminal plate 3 and the mounting groove 141 are floatingly connected.

[0029] The terminal block 3 of the fan 10 is provided with a cable routing hole 32, through which the wire 2 can be connected to the terminal block 3. The mounting area 11 of the fan frame 1 is provided with a mounting groove 141, and the terminal block 3 can be movably inserted into the mounting groove 141, so that the wire 2 and the terminal block 3 are located in the same area on the fan frame 1. The terminal block 3 can be restricted within the mounting groove 141 by connecting the first limiting hole 131 and the second limiting hole 31 through the limiting component 4. At the same time, the inner diameter of the second limiting hole 31 is larger than at least part of the diameter of the limiting component 4, which can realize the floating installation of the terminal block 3 within the mounting groove 141, reducing the impact of vibration on the connection stability between the connector 100 and the terminal block 3. Furthermore, the setting of the cable routing hole 32 makes it possible to fix and install the wire 2 without the use of additional parts, reducing the assembly difficulty of the fan 10, ensuring the heat dissipation space inside the electronic device 200, improving heat exchange efficiency, and reducing the computational load of the heat dissipation system.

[0030] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the embodiments and features described below can be combined with each other.

[0031] In the following text, for ease of explanation, we define the first direction X as the X-axis direction, the second direction Y as the Y-axis direction, and the third direction Z as the Z-axis direction, and the first direction X, the second direction Y and the third direction Z are orthogonal to each other.

[0032] In some embodiments, the fan frame 1 serves as the housing of the fan 10, providing a stable mounting structure for other components of the fan 10 and ensuring their safe operation. Simultaneously, it protects the internal components of the fan 10 from external factors such as dust, humidity, or other physical damage. The fan frame 1 used in this application is made of plastic or metal, and the choice is made according to actual needs; no limitation is made here.

[0033] The installation area 11 can be any area on the fan frame 1. For example, it can be the end face area of ​​the fan frame 1 or the side area of ​​the fan frame 1. It can be selected according to the arrangement of the fan 10 inside the electronic device, as long as it is convenient to connect with the connector 100. There is no limitation here.

[0034] Please refer to Figure 3. The mounting area 11 is provided with a first limiting member 13, a first mounting plate 14, and a second mounting plate 15. The first mounting plate 14 and the second mounting plate 15 are arranged opposite each other along the second direction Y. The first limiting member 13 has a first limiting hole 131 extending along the first direction X. The first mounting plate 14 and the second mounting plate 15 have mounting grooves 141 extending along the second direction Y. Viewed along the first direction X, the first mounting plate 14 and the second mounting plate 15 are located on opposite sides of the first limiting member 13. It can be understood that the axis of the first limiting hole 131 extends along the first direction X, and the mounting grooves 141 on the first mounting plate 14 and the second mounting plate 15 are on the same straight line along the second direction Y, that is, the axis of the first limiting hole 131 along the first direction X is perpendicular to the through direction of the mounting groove 141.

[0035] It should be noted that this application does not limit the depth and width of the mounting groove 141, and can be selected according to the size of the terminal block 3.

[0036] In this application, the first limiting member 13, the first mounting plate 14, and the second mounting plate 15 can be integrally formed with the fan frame 1, or they can be combined. The combined structure includes bonding, welding, or detachable connections. It is understood that when the components of the mounting area 11 are integrally formed, bonded, or welded with the fan frame 1, the overall strength of the fan frame 1 is high, and its service life is longer. When the components of the mounting area 11 are detachable from the fan frame 1, such as the mating connection of a protrusion and a groove, if a component of the mounting area 11 is damaged, it can be replaced individually, reducing the maintenance cost of the fan 10.

[0037] Optionally, the first limiting member 13, the first mounting plate 14, and the second mounting plate 15 are integrally formed with the fan frame 1. Understandably, since the components of the mounting area 11 are integrally formed with the fan frame 1, no additional fixing components are needed to fix the first limiting member 13, the first mounting plate 14, and the second mounting plate 15 to the fan frame 1. This results in a smaller system space occupied by the first limiting member 13, the first mounting plate 14, and the second mounting plate 15. Furthermore, the fixing and installation of the wires 2 and the terminal block 3 do not require additional fixing components, ensuring sufficient heat dissipation space inside the electronic device, improving heat exchange efficiency, reducing the computational load of the heat dissipation system, while also increasing the strength and extending the service life of the fan frame 1.

[0038] In some embodiments, the terminal block 3 is used for connecting the fan 10 to a power supply or control system, providing an electrical interface to the connector 100 so that the fan 10 can receive power and operate. Specifically, referring to Figure 4, the terminal block 3 has electrical contact areas 33 distributed on both surfaces of the terminal block 3, and at least some of the electrical contact areas 33 have different areas. It is understood that the electrical contact areas 33 are used for electrical connection with the connector 100. The fact that the electrical contact areas 33 are distributed on both sides of the terminal block 3 and have different areas provides more contact surface, helping to ensure a more stable electrical connection. In a vibrating environment, larger contacts can reduce the risk of open circuits due to poor contact, improving the reliability and durability of the fan 10.

[0039] Terminal plate 3 is inserted into the mounting groove 141 of the first mounting plate 14 and the second mounting plate 15, and the thickness of the contact portion between terminal plate 3 and mounting groove 141 is less than the width of mounting groove 141, that is, terminal plate 3 can be displaced within mounting groove 141 along the first direction X. It is understandable that in actual installation, due to manufacturing tolerances, assembly errors, etc., there may be some alignment issues when connector 100 and terminal plate 3 are mated. The fact that terminal plate 3 can move within mounting groove 141 along the first direction X allows for smooth mating between terminal plate 3 and connector 100, simplifying the installation process and reducing stress concentration caused by forced alignment. This application does not limit the thickness difference between mounting groove 141 and terminal plate 3; it can be selected according to the specific application scenario and specifications of fan 10.

[0040] The terminal plate 3, which is movably inserted into the mounting groove 141, has a second limiting hole 31 that extends through the thickness direction. When the terminal plate 3 is installed into the mounting groove 141, the second limiting hole 31 coincides with the first limiting hole 131 of the first limiting member 13 along the axis of the first direction X. By connecting the first limiting hole 131 and the second limiting hole 31 through the limiting component 4, the terminal plate 3 and the mounting groove 141 can be floated and connected.

[0041] In this embodiment, the floating connection refers to a situation where, when the terminal block 3 is installed in the mounting groove 141, the size of the mounting groove 141 is larger than the size of the mounting portion of the terminal block 3, and there is a certain gap between the terminal block 3 and the mounting groove 141, allowing the terminal block 3 to move slightly in one or more directions. It is understood that floating installation can eliminate certain installation errors, ensure proper alignment between the terminal block 3 and the connector 100, and, to a certain extent, play a role in shock absorption and buffering, reducing the impact of mechanical vibration of the fan frame during the rotation of the fan 10 on the connection stability between the terminal block 3 and the connector 100.

[0042] Please refer to Figure 5. The limiting component 4 includes an expansion member 41 and a first positioning pin 42. The expansion member 41 passes through the first limiting hole 131. The first limiting hole 131 includes a first hole segment 1311 and a second hole segment 1312. The second hole segment 1312 is located at the end of the first hole segment 1311 away from the installation area 11, and the diameter of the second hole segment 1312 is larger than the diameter of the first hole segment 1311. The expansion member 41 includes an expansion body 412 and a second limiting part 413. The diameter of the second limiting part 413 is larger than the inner diameter of the first hole segment 1311. The expansion body 412 passes through the first hole segment 1311, and the second limiting part 413 is received in the second hole segment 1312. The second limiting part 413 is not protruding from the surface of the first limiting member 13. Understandably, the second limiting part 413 does not protrude from the surface of the first limiting part 13, which improves the aesthetics and reduces the impact of other components inside the fan on the limiting assembly 4, ensuring the stable installation of the limiting assembly 4.

[0043] The expansion member 41 has an expansion hole 411. When the expansion member 41 is embedded in the first limiting hole 131, the second limiting hole 31 and the expansion hole 411 coincide along the axis of the first direction X. The first positioning pin 42 includes a first limiting part 421 and a pin body 422 connected together. The diameter of the pin body 422 is smaller than the diameter of the second limiting hole 31. The pin body 422 passes through the expansion hole 411 and the second limiting hole 31. The first limiting part 421 abuts against the surface of the first limiting member 13 away from the installation area 11. The pin body 422 causes at least a portion of the expansion member 41 to expand and deform in a direction perpendicular to the axis of the expansion hole 411. It can be understood that after the first positioning pin 42 passes through the expansion member 41 and deforms, a portion of the diameter of the expansion member 41 is larger than the diameter of the first limiting hole 131, which can ensure that the first positioning pin 42 will not detach from the first limiting hole 131, thereby ensuring the stable installation of the terminal board 3 in the mounting groove 141 during operation.

[0044] By cooperating with the expansion member 41, the first positioning pin 42 and the mounting groove 141, the terminal block 3 can be confined within the mounting groove 141, realizing the floating installation of the terminal block 3 within the mounting groove 141, reducing the impact of vibration during the rotation of the fan 10 on the connection stability between the connector 100 and the terminal block 3.

[0045] In some embodiments, referring to Figure 4, the wiring holes 32 on the terminal board 3 are linearly arranged and symmetrically distributed on both sides of the second limiting hole 31 along its length. The wire 2 can then pass through the wiring holes 32 and be soldered to the terminal board 3, thus fixing the conductive wire and the terminal board 3 in the same area. It is understood that after the wire 2 is connected to the wiring holes 32, it is distributed on both sides of the second limiting hole 31, meaning the terminal board 3 and the limiting component 4 are centrally connected. When the connector 100 is inserted into the terminal board 3, the terminal board 3 experiences more uniform force, accelerating the connection speed. Furthermore, the arrangement of the wire 2 does not affect the limiting process of the limiting component 4 on the terminal board 3. The wiring of the wire 2 is more rational, further increasing the heat dissipation space inside the electronic device.

[0046] In practical applications, the terminal block 3 is inserted into the mounting groove 141 along the third direction Z, and the expansion member 41 is embedded in the first limiting hole 131. The first positioning pin 42 passes through the second limiting hole 31 and the expansion hole 411, so that the expansion member 41 deforms in the direction away from the axis of the expansion hole 411, ensuring that the first positioning pin 42 will not disengage from the first limiting hole 131, thereby realizing the floating connection of the terminal block 3 in the mounting groove 141.

[0047] Example 2

[0048] Unlike Embodiment 1, the structure and assembly method of the limiting component 4 are different. Specifically:

[0049] Please refer to Figures 6-10. The limiting component 4 includes a positioning body 43 and a second positioning pin 44. At least a portion of the positioning body 43 is embedded in the first limiting hole 131, and the positioning body 43 does not protrude from the surface of the first limiting component 13 after installation. It is understandable that the above installation method improves the aesthetics of the installation area 11 while reducing the impact of other components on the positioning body 43, ensuring the stable installation of the positioning body 43.

[0050] The surface of the positioning body 43 facing the installation area 11 is provided with a first positioning post 431. The first positioning post 431 is a columnar structure. The diameter of the columnar structure is smaller than the diameter of the first limiting hole 131 and the second limiting hole 31. The first positioning post 431 can connect the first limiting hole 131 and the second limiting hole 31 to ensure that the terminal board 3 will not be dislodged from the installation groove 141 along the installation direction.

[0051] The positioning body 43 has a first positioning hole 432 extending along the third direction Z. The first limiting member 13 has a second positioning hole 132 at its top along the third direction Z. The first positioning hole 432 and the second positioning hole 132 coincide along the axis of the third direction Z. The cross-sectional shape of the first positioning hole 432, the second positioning hole 132, and the first positioning post 431 can be circular or other polygonal, which can be selected according to actual needs and is not limited here. The second positioning pin 44 can be installed along the third direction Z into the first positioning hole 432 and the second positioning hole 132, so that the limiting component 4 is fixed in the first limiting hole 131. It can be understood that by fixing the positioning body 43 in the first limiting hole 131 by the second positioning pin 44, the limiting component 4 occupies less system space, which can further increase the heat dissipation space inside the electronic device.

[0052] In practical application, the terminal block 3 is inserted into the mounting groove 141 along the third direction Z, and the positioning body 43 is embedded in the first limiting hole 131. The first positioning pin 431 passes through the first limiting hole 131 and the second limiting hole 31. At the same time, the second positioning pin 44 can be installed along the third direction Z to the first positioning hole 432 and the second positioning hole 132, so that the positioning body 43 is fixed in the first limiting hole 131, completing the fixing process of the limiting component 4. At this time, the terminal block 3 is floating in the mounting groove 141.

[0053] Example 3

[0054] Unlike Embodiment 1, the structure and assembly method of the limiting component 4 are different. Specifically:

[0055] Please refer to Figures 11-15. The limiting component 4 includes a limiting plate 45. The limiting plate 45 is located on the side of the first limiting member 13 away from the installation area 11. A second positioning post 451 is provided on the surface of the limiting plate 45 facing the installation area 11. The second positioning post 451 passes through the first limiting hole 131 and the second limiting hole 31. The diameter of the second positioning post 451 is smaller than the inner diameter of the first limiting hole 131 and the second limiting hole 31. By setting the second positioning post 451, the limiting plate 45 can be initially snapped into the installation area 11, and the terminal plate 3 can be floatingly connected to the installation groove 141.

[0056] The limiting component 4 also includes a snap-fit ​​arm 452, which extends from the wall of the limiting plate 45 towards the first mounting plate 14 and the second mounting plate 15. Specifically, the snap-fit ​​arm 452 includes a first extension arm 4522 and a second extension arm 4523 connected and perpendicularly arranged. The second extension arm 4523 is bent from the end of the first extension arm 4522 away from the limiting plate 45 towards the first mounting plate 14 and the second mounting plate 15. A latching portion 4521 is provided at the end of the second extension arm 4523 away from the limiting plate 45. It should be noted that the length of the first extension arm 4522 is greater than the distance between the first mounting plate 14 and the second mounting plate 15, and the length of the second extension arm 4523 is greater than the width of the first mounting plate 14 and the second mounting plate 15 along the first direction X, so that after the limiting plate 45 is installed, the latching portion 4521 can snap onto the side of the first mounting plate 14 and the second mounting plate 15 away from the limiting plate 45.

[0057] It should be noted that this application does not limit the specific structure of the buckle part 4521. It can be a triangular buckle or a rectangular buckle, etc. The buckle arm 452 can be stably connected to the first mounting plate 14 and the second mounting plate 15. It can be selected according to actual needs.

[0058] Furthermore, the first mounting plate 14 and the second mounting plate 15 are provided with snap-fit ​​grooves 142 on the sidewalls near the first limiting member 13. The snap-fit ​​grooves 142 can be used to accommodate at least a portion of the first extension arm 4522. It is understood that accommodating at least a portion of the first extension arm 4522 in the snap-fit ​​grooves 142 can reduce the distance between the limiting plate 45 and the terminal plate 3 after the limiting assembly 4 is installed, thereby reducing the system space occupied by the limiting assembly 4 along the first direction X.

[0059] After the second positioning post 451 connects the first limiting hole 131 and the second limiting hole 31, it can restrict the terminal plate 3 from leaving the limiting groove. Furthermore, the snap-fit ​​part 4521 of the snap-fit ​​arm 452 can prevent the limiting protrusion from leaving the first limiting hole 131 by snapping with the first mounting plate 14 and the second mounting plate 15, thus ensuring the stable installation of the terminal groove.

[0060] In practical application, the terminal block 3 is inserted into the mounting groove 141 along the third direction Z. The second positioning post 451 of the limiting plate 45 connects the first limiting hole 131 and the second limiting hole 31, and the snap-fit ​​part 4521 can snap with the side of the first mounting plate 14 and the second mounting plate 15 away from the limiting plate 45. The first extension arm 4522 is received in the snap-fit ​​groove 142, so that the limiting plate 45 is stably installed in the mounting area 11, thereby limiting the terminal block 3. At this time, the terminal block 3 is floating in the mounting groove 141.

[0061] It should be noted that the diameter of the contact portion between the limiting component 4 and the second limiting hole 31 of the terminal plate 3 is smaller than the inner diameter of the second limiting hole 31, so that the floating of the terminal plate 3 in the first direction X, the second direction Y and the third direction Z is not affected. This application does not limit the diameter difference, and it can be selected according to the specific application scenario and specifications of the fan 10.

[0062] It should also be noted that the shape of the terminal block 3 matches the shape of the connector 100. The type of connector 100 can be selected according to actual needs, and no limitation is made here.

[0063] Example 4

[0064] Please refer to Figures 16, 17 and 18. Unlike Embodiments 1, 2 and 3, the installation area 11 is also provided with a second limiting member 12. The first limiting member 13, the second limiting member 12, the first mounting plate 14 and the second mounting plate 15 are integrally formed with the installation area 11.

[0065] Specifically, the second limiting member 12 and the first limiting member 13 are arranged opposite each other along the first direction X, and the second limiting member 12 is provided with a third limiting hole 121 that passes through along the first direction X. Viewed along the first direction X, the first mounting plate 14 and the second mounting plate 15 are located on both sides of the second limiting member 12 and the first limiting member 13. It can be understood that the third limiting hole 121 and the first limiting hole 131 coincide along the axis of the first direction X, and the mounting grooves 141 opened on the first mounting plate 14 and the second mounting plate 15 are located on the same straight line along the second direction Y, that is, the axis of the third limiting hole 121 and the first limiting hole 131 along the first direction X is perpendicular to the through direction of the mounting groove 141.

[0066] The terminal plate 3, which is movably inserted into the mounting groove 141, is located between the second limiting member 12 and the second limiting part 413 along the first direction X. The terminal plate 3 has a second limiting hole 31 that extends through the thickness direction. When the terminal plate 3 is installed into the mounting groove 141, the second limiting hole 31 coincides with the third limiting hole 121 of the second limiting member 12 and the first limiting hole 131 of the first limiting member 13 along the axis of the first direction X. By connecting the third limiting hole 121, the first limiting hole 131 and the second limiting hole 31 through the limiting component 4, the terminal plate 3 and the mounting groove 141 can be floated and connected.

[0067] Example 5

[0068] Unlike Embodiments 1, 2, 3 and 4, the fan also includes a shock absorber 5.

[0069] Referring to Figure 19, taking the structure of the fan 10 in Embodiment 2 as an example, the shock absorber 5 is disposed within the mounting groove 141 and located between the surface of the terminal plate 3 and the wall surface (side wall surface and bottom wall surface) of the mounting groove 141. It is understood that the fan will generate certain vibrations during operation. These vibrations are transmitted to the terminal plate 3 through the contact between the mounting groove 141 and the terminal plate 3, affecting the connection stability between the terminal plate 3 and the connector 100. By providing the shock absorber 5 between the surface of the terminal plate 3 and the wall surface of the mounting groove 141, the impact of fan vibration on the connection stability between the terminal plate 3 and the connector 100 can be further reduced.

[0070] It is understandable that, except for the structure shown in Embodiment 2, the arrangement of the shock absorber 5 in the mounting groove 141 can also be applied to Embodiments 1, 3 and 4.

[0071] As an optional technical solution of this application, unlike embodiments 1 to 5, the limiting component 4 may not be provided. Instead, a structural component for opening or closing the entrance of the mounting groove 141 of the first mounting plate 14 and the second mounting plate 15 may be provided. This structural component includes, but is not limited to, a baffle, a pin-hole mating structure installed along the first direction, or an elastic clip, etc., which can open or close the mounting groove 141. It is understood that when the terminal plate 3 is installed into the mounting groove 141 along a third direction, the structural component closing the entrance of the mounting groove 141 can prevent the terminal plate 3 from detaching from the entrance, thus achieving a floating connection between the terminal plate 3 and the mounting groove 141.

[0072] As an optional technical solution of this application, unlike embodiments 1 to 5, the limiting component 4 and the mounting groove 141 may not be provided. Instead, mounting holes extending in the second direction are opened on the first mounting plate 14 and the second mounting plate 15. Mounting rods are provided at both ends of the terminal plate 3. The inner diameter of the mounting hole is larger than the diameter of the mounting rod. The side walls of the first mounting plate 14 and the second mounting plate 15 are provided with mounting channels communicating with the mounting holes. The mounting channels include at least one bent portion. It can be understood that the terminal plate 3 can enter the mounting hole through the mounting rod along the mounting channel, so that the mounting rod can move in the mounting hole in the first and second directions. Due to the bent path of the mounting channel, the terminal plate 3 will not detach from the mounting hole.

[0073] As an optional technical solution of this application, unlike embodiments 1 to 5, the limiting component 4 and the mounting groove 141 may not be provided. Instead, a first mounting hole extending along the second direction is opened on the first mounting plate 14 and the second mounting plate 15, and second mounting holes are respectively opened on both sides of the terminal plate 3 along the second direction. The fan 10 also includes a mounting pin, the diameter of which is smaller than the diameter of the mounting hole. It can be understood that the terminal plate 3 can be installed in the mounting area 11. After the mounting pin passes through the first mounting hole, it connects with the second mounting hole of the terminal plate. At this time, the mounting pin can move within the first mounting hole, thereby realizing the floating installation of the terminal plate 3 in the mounting area.

[0074] It should be noted that the shapes of the first limiting hole 131, the second limiting hole 31, the third limiting hole 121, the first positioning hole 432, the second positioning hole 132 and the cable hole 32 provided in this application are including but not limited to round holes or other polygonal holes, and can be selected according to actual needs, without limitation here.

[0075] This application also provides an electronic device 200, which includes, but is not limited to, a server, a switch, or a router. Referring to FIG20, taking the central processing unit 201 of the server as an example, the main internal components of the central processing unit 201 include an arithmetic unit 2011, a controller 2012, and a register 2013. The arithmetic unit 2011 is used for arithmetic and logical operations, the controller 2012 directs and coordinates the work of other components to ensure the orderly operation of all parts of the computer, and the register 2013 is used to temporarily store instructions, data, and addresses, enabling the central processing unit 201 to quickly obtain information and improve processing efficiency. The operation of components such as the arithmetic unit 2011, the controller 2012, and the register 2013 generates heat. At this time, the fan 10 can promote airflow and remove the heat from the heat sink to ensure that the central processing unit 201 operates at a suitable temperature and prevent the central processing unit 201 from degrading in performance or being damaged due to overheating.

[0076] In addition to the example above, the fan 10 can be applied to other electronic devices 200, and the number of fans 10 is not limited to eight. Eight is just an example. More fans 10, such as ten or twelve, can be used, or fewer fans 10, such as one, two or four, can be used. The type of electronic device 200 and the number of fans 10 can be selected according to actual needs, and there are no limitations here.

[0077] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
