Description

Technical Field

[0001] The present invention relates to the field of hard disk installation, and particularly to a hard disk installation module, a chassis and an electronic device. Background Art

[0002] A PCB (Printed Circuit Board) is a support for electronic components, providing a basis for the electrical connection of electronic components. The connectors on the PCB achieve the transmission of signals or currents through the contact connection between the male end and the female end.

[0003] Wire-end connectors and board-end connectors are two common types of connectors. Wire-end connectors are designed specifically for the end connection of wires or cables, mainly used to achieve the connection between wires and wires, or between wires and devices; board-end connectors are often directly installed on printed circuit boards, generally in the form of pins or sockets, and can be directly soldered or fixed on the PCB through pads or slots for connection with other electronic components or cables; wire-end connectors are more flexible and have low space requirements, but they need to be disassembled and cannot be fixed to the board, resulting in poor connection stability; although board-end connectors have good connection stability with the board, they have high precision requirements for the plugging and mating process.

[0004] In the related art, when installing devices such as hard disks, generally, board-end connectors are installed on a vertically arranged board. The slots of the board-end connectors extend in the horizontal direction, and the hard disks are arranged vertically and installed in the slots in the horizontal direction. In order to achieve the heat dissipation of the board-end connectors and the hard disks, ventilation slots also need to be opened on the board. Since the ventilation slots occupy the area of the board, when installing the same number of hard disks, the area of the board needs to be increased, thus occupying more space; the air flow can only pass through the ventilation slots, resulting in poor heat dissipation effect; and, due to the fixed position of the board-end connectors, the installation of the hard disks is restricted, and the applicable range is small.

[0005] Therefore, how to improve the usability of the hard disk installation module is a technical problem that those skilled in the art need to solve currently. Summary of the Invention

[0031] The present invention also provides an electronic device, comprising any one of the hard disk installation modules described above.

[0032] The hard disk installation module provided by the present invention has the following beneficial effects: By placing the board in the heat dissipation channel, and the board extends along the air flow direction of the heat dissipation channel, it is to enable the air flow to flow over the surface of the board; Since the air flow passes over the surface of the board, there is no need to open ventilation slots on the board, reducing the area of the board occupied by the ventilation slots, which is conducive to the miniaturization of the volume of the board. Moreover, it avoids the problem in the related art that the air flow can only pass through the ventilation slots, resulting in a small gas flow and poor heat dissipation effect. The hard disk installation module makes the air flow pass along the entire surface of the board by setting the board perpendicular to the air flow direction of the heat dissipation channel, with a large gas flow and significantly improved heat dissipation effect; And, through the setting of the connector body, the connector body is provided with an input connection end and an output connection end. The input connection end is for the hard disk to be plugged in, and the hard disk can be components such as a hard disk. The output connection end is used to connect with a cable, and the cable is connected to the server motherboard or the motherboard of other devices to realize the information transmission between the hard disk and the server or other devices; The connector body is also provided with a signal connection end, and a board connection part is provided on the surface of the board. The signal connection end is connected to the board connection part to realize the expansion function of the board; Further, the insertion direction of the signal connection end on the connector body is perpendicular to the plane where the board is located, that is, the installation between the connector body and the board is perpendicular to the board, and the insertion direction of the input connection end is parallel to the plane where the board is located, that is, the installation between the hard disk and the connector body is parallel to the board; With such a setting, since the installation method of the board has changed compared with the related art, from being perpendicular to the air flow direction in the related art to being parallel to the air flow direction, not only the area of the board is reduced, but also the air flow flows on the surface of the board, improving the heat dissipation effect. At the same time, since the insertion direction of the signal connection end on the connector body is perpendicular to the plane where the board is located, and the insertion direction of the input connection end is parallel to the plane where the board is located, that is, the insertion direction of the signal connection end is perpendicular to the insertion direction of the input connection end. With such a setting, although the installation direction of the board has changed, through the setting of the connector body, the installation direction of the hard disk will not change, and the layout of other components in the device body, such as the chassis, will not change, and it can be directly modified in related devices, saving costs; For example, when the hard disks are all arranged vertically, in the related art, the board extends vertically, and the hard disk needs to be inserted horizontally into the board end connector of the board. In this application, the board is arranged horizontally, the connector body is installed vertically, and the hard disk is also inserted horizontally into the input connection end of the connector body.

[0033] The hard disk installation module provided by the present invention can adjust the extending direction of the board, and at the same time, in cooperation with the input connection end and the signal connection end in the connector body, enables the air flow to flow through the surface of the board without affecting the hard disk installation direction. This not only reduces the setting of ventilation slots, decreases the area of the board, but also can increase the contact area between the air flow and the board, effectively improving the heat dissipation efficiency.

[0034] In one embodiment, the connector body includes a wire-end connector body and a board-end connector body. The board-end connector body is installed on the board, and the wire-end connector body is detachably connected to the board-end connector body; and the input connection end and the output connection end are located on the wire-end connector body, and the signal connection end is located on the board-end connector. With the above settings, by setting the connector body as a split structure, the firm connection between the board-end connector body and the board is utilized to ensure the stability of the connector body, and the flexibility brought by the cable connection is fully utilized by the setting of the wire-end connector body; by setting the input connection end and the output connection end on the wire-end connector body, it is convenient for the disassembly and assembly of the hard disk and the connection of the cable, and by setting the signal connection end on the board-end connector body, the connection stability between the board-end connector body and the connection part of the board is ensured, thereby ensuring that the board can achieve the expansion function; at the same time, by using the detachable connection between the wire-end connector body and the board-end connector body, the required wire-end connector body can be selected according to needs to be applicable to different types of hard disks, that is, the input connection end on the wire-end connector body can be connection ends of different types of interfaces.

[0035] The chassis provided by the present invention is provided with the above hard disk installation module. Since the hard disk installation module has the above technical effects, the chassis provided with this hard disk installation module should also have corresponding technical effects.

Detailed implementation manners

[0060] The core of the present invention is to provide a hard disk installation module, a chassis and an electronic device, which can change the installation direction of the hard disk and reduce the influence caused by a relatively small installation space.

[0061] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0062] In this embodiment, please refer toFigure 1 , Figure 7 and Figure 10 , the hard disk mounting module includes:

[0063] Board 1, on the surface of which there is a board connection part, and Board 1 is used to be placed in the heat dissipation channel and extend along the air flow direction of the heat dissipation channel;

[0064] Connector body 2, provided with an input connection end 211, an output connection end 212 and a signal connection end 221. The input connection end 211 is used to install the hard disk 3, the output connection end 212 is used to connect the cable 23, and the signal connection end 221 is used to connect the board connection part;

[0065] Moreover, the insertion direction of the signal connection end 221 is perpendicular to the plane where Board 1 is located, and the insertion direction of the input connection end 211 is parallel to the plane where Board 1 is located.

[0066] Specifically, the function of this hard disk mounting module is to fix the hard disk 3 on Board 1 and connect the connector body 2 to the server motherboard or the motherboard of other devices through the cable 23, which can not only meet the position fixation of the hard disk 3, but also utilize the connection flexibility of the cable 23; the board connection part can be a plug-in terminal of Board 1. After the connector body 2 is installed on Board 1, the signal connection end 221 will be connected to the board connection part, so as to realize the signal transmission between the connector body 2 and Board 1; specifically, the hard disk mounting module is used to transmit the signals between the central processing unit on the server motherboard and the hard disk 3. The signals between the hard disk 3 and the server motherboard are usually high-speed signals, and different types of hard disks 3 require different cables 23; further, the cable 23 is selected as a high-speed signal cable, and the high-speed signal cable can include a high-speed clock signal cable and a high-speed data signal cable; the high-speed signal cable is usually a peripheral component interconnect express (PCI-Express, PCI-Express or PCIe), then at this time, the high-speed signals between the connector body 2 and the server motherboard can include a high-speed serial computer expansion bus data signal and a high-speed serial computer expansion bus clock signal.

[0067] The hard disk installation module places the board 1 in the heat dissipation channel, and the board 1 extends along the air flow direction of the heat dissipation channel, so that the air flow can flow over the surface of the board 1; since the air flow passes through the surface of the board 1, there is no need to open ventilation slots on the board 1, reducing the area of the board 1 occupied by the ventilation slots, which is conducive to the miniaturization of the volume of the board 1. Moreover, it avoids the problem in the related technology that the air flow can only pass through the ventilation slots, resulting in a small gas flow and poor heat dissipation effect. The hard disk installation module makes the air flow pass along the entire surface of the board 1 by setting the board 1 perpendicular to the air flow direction of the heat dissipation channel, with a large gas flow and significantly improved heat dissipation effect. And, through the setting of the connector body 2, the connector body 2 is provided with an input connection end 211 and an output connection end 212. The input connection end 211 is for the hard disk 3 to be plugged in, and the output connection end 212 is used to connect with the cable 23. The cable 23 is connected to the server motherboard or the motherboard of other devices to realize the information transfer between the hard disk 3 and the server or other devices; the connector body 2 is also provided with a signal connection end 221, and the surface of the board 1 is provided with a board connection part. The signal connection end 221 is connected to the board connection part to realize the expansion function of the board 1; further, the insertion direction of the signal connection end 221 on the connector body 2 is perpendicular to the plane where the board 1 is located, that is, the installation between the connector body 2 and the board 1 is perpendicular to the board 1, and the insertion direction of the input connection end 211 is parallel to the plane where the board 1 is located, that is, the installation between the hard disk 3 and the connector body 2 is parallel to the board 1; with such a setting, since the installation method of the board 1 has changed compared with the related technology, from being perpendicular to the air flow direction in the related technology to being parallel to the air flow direction, not only the area of the board 1 is reduced, but also the air flow flows on the surface of the board 1, improving the heat dissipation effect. At the same time, since the insertion direction of the signal connection end 221 on the connector body 2 is perpendicular to the plane where the board 1 is located, and the insertion direction of the input connection end 211 is parallel to the plane where the board 1 is located, that is, the insertion direction of the signal connection end 221 is perpendicular to the insertion direction of the input connection end 211. With such a setting, although the installation direction of the board 1 has changed, through the setting of the connector body 2, the installation direction of the hard disk 3 will not change, and the layout of other components in the device body, such as the chassis, will not change, and it can be directly modified in related devices, saving costs; for example, when the hard disks 3 are all arranged vertically, in the related technology, the board 1 extends vertically, and the hard disk 3 needs to be inserted horizontally into the board end connector of the board 1. In this application, the board 1 is arranged horizontally, the connector body 2 is installed vertically, and the hard disk 3 is also inserted horizontally into the input connection end 211 of the connector body 2.

[0068] The hard disk installation module provided by the present invention can adjust the extension direction of the board 1 and, in conjunction with the settings of the input connection end 211 and the signal connection end 221 in the connector body 2, enable the air flow to pass through the surface of the board 1 without affecting the installation direction of the hard disk 3. This not only reduces the setting of ventilation slots and the area of the board 1, but also increases the contact area between the air flow and the board 1, effectively improving the heat dissipation efficiency.

[0069] In some embodiments, please refer to Figures 10 to 13 , the connector body 2 includes a wire-end connector body 21 and a board-end connector body 22. The board-end connector body 22 is installed on the board 1, and the wire-end connector body 21 is detachably connected to the board-end connector body 22; the input connection end 211 and the output connection end 212 are located on the wire-end connector body 21, and the signal connection end 221 is located on the board-end connector; specifically, the wire-end connector body 21 and the board-end connector body 22 can be connected by plugging or through other structural members; by setting the connector body 2 as a split structure, the firm connection between the board-end connector body 22 and the board 1 is used to ensure the stability of the connector body 2, and the setting of the wire-end connector body 21 can make full use of the flexibility brought by the connection of the cable 23; by setting the input connection end 211 and the output connection end 212 on the wire-end connector body 21, it is convenient for the disassembly and assembly of the hard disk 3 and the connection of the cable 23, and setting the signal connection end 221 on the board-end connector body 22 ensures the connection stability between the board-end connector body 22 and the board connection part, thus ensuring that the board 1 can achieve extended functions; at the same time, using the detachable connection between the wire-end connector body 21 and the board-end connector body 22, the required wire-end connector body 21 can be selected according to needs to be applicable to different types of hard disks 3, that is, the input connection end 211 on the wire-end connector body 21 can be interface connection ends of different types, such as U.2 interface connection ends or E3.s connection ends; the U.2 interface, also known as SFF-8639, is a physical connector standard mainly used to connect high-performance solid-state drives to computer systems; it can provide higher bandwidth and lower latency, and is suitable for applications that process a large amount of data and require fast access; E3.s is a part of the EDSFF (Enterprise and Datacenter Standard FormFactor) standard, which is a form factor specification for solid-state drives designed for enterprises and data centers.

[0070] In some embodiments, please refer to Figures 17 to 20, a board - end pin 222 is provided at the bottom of the board - end connector body 22. Positioning holes are provided on the board 1, and the positions of the board - end pins 222 correspond one - to - one with those of the positioning holes. Moreover, the signal connection end 221 is located on one side of the board - end connector body 22 close to the board - end pin 222. Specifically, the board - end pins 222 can be arranged at the bottom corners of the board - end connector body 22. The signal connection end 221 is located on one side of the board - end connector body 22 close to the board - end pin 222. Such an arrangement is to ensure that after the board - end pins 222 are fixedly connected to the positioning holes, the signal connection end 221 can be firmly connected to the board - card connection part. Specifically, the cross - section of the board - end connector body 22 can be square. By arranging the board - end pins 222 at the four bottom corners of the board - end connector body 22, the connection stability between the board - end connector body 22 and the board 1 can be guaranteed. Further, the signal connection end 221 is located at the middle position of the bottom of the board - end connector body 22, which is convenient for cooperation with the board - card connection part. The sizes of the board - end pins 222 and the positioning holes are adapted to each other. After the board - end pins 222 are inserted into the positioning holes, the board - end pins 222 and the positioning holes are welded together to realize the fixed connection between the board - end pins 222 and the positioning holes, and further realize the fixed connection between the board - end connector body 22 and the board 1. Of course, the setting position of the board - end pins 222 can also be set as required, not limited to the way given in this embodiment. And the connection method between the board - end connector body 22 and the board 1 is not limited to the way of the board - end pins 222 and the positioning holes. Other methods can also be selected, such as directly welding the board - end connector body 22 on the board 1, or fixing the board - end connector body 22 and the board 1 through other structural parts.

[0071] In some embodiments, the input connection end 211 and the output connection end 212 are respectively located on the left and right sides of the wire - end connector body 21. A gold finger 213 is provided at the bottom of the wire - end connector body 21, and the gold finger 213 is used to connect with the board - end connector body 22. Specifically, for the convenience of installing the hard disk 3, the input connection end 211 and the output connection end 212 are respectively arranged on the left and right sides of the wire - end connector body 21. The left - right direction of the wire - end connector body 21 can be parallel to the air - flow direction in the heat - dissipation channel. Such an arrangement can reduce the influence of the input connection end 211 and the output connection end 212 on the air flow and ensure the heat - dissipation effect. At the same time, the input connection end 211 can be suspended on the side of the board 1. In this way, when the hard disk 3 is installed, it will not contact the board 1, and the interference between the hard disk 3 and the board 1 can be avoided. Therefore, the bottom height of the hard disk 3 can be set to be lower than the height of the position where the board 1 is located, and the utilization of space is more flexible. The installation position of the hard disk 3 can be not affected by the position of the board 1. Further, by providing the gold finger 213 at the bottom of the wire - end connector body 21 and using the gold finger 213 to connect with the board - end connector body 22, the installation is convenient and the signal - transmission effect is stable.

At the same time, the gold finger 213 is located on the wire-end plug-in portion 214, and the board-end slot 223 is located in the board-end plug-in cavity 225. When the wire-end plug-in portion 214 is inserted into the board-end plug-in cavity 225, the wire-end plug-in portion 214 will drive the gold finger 213 to move to cooperate with the board-end slot 223 in the board-end plug-in cavity 225, thereby realizing the connection between the gold finger 213 and the slot terminal 224.

[0074] In some embodiments, the bottom height of the wire-end plugging portion 214 is higher than the bottom height of the side of the wire-end connector body 21 close to the input connection end 211, that is, a height difference is formed between the bottom of the wire-end plugging portion 214 and the bottom of the side of the wire-end connector body 21 close to the input connection end 211, which can provide an avoidance space 24 for the board-end connector body 22; such a setting is to reduce the height of the entire connector body 2, thereby reducing the occupied space of the hard disk 3 installation module. Further, after the board-end connector body 22, the wire-end plugging portion 214 are assembled and the board 1 is assembled, the bottom height of the side of the wire-end connector body 21 close to the input connection end 211 is lower than the surface of the board 1; specifically, the wire-end connector body 21 has an L-shaped structure, an avoidance space 24 is formed between the two side edges of the wire-end connector body 21, the board-end connector body 22 is located in the avoidance space 24, and the overall structure layout is compact, which can make the best use of the space.

[0075] In some embodiments, guiding steps 215 are provided on both sides of the wire-end plugging portion 214, guiding sliding grooves 226 are formed on both side walls of the board-end connector body 22, and the shapes of the guiding steps 215 and the guiding sliding grooves 226 are adapted to each other for the guiding steps 215 to slide along the guiding sliding grooves 226; specifically, through the cooperative sliding of the guiding steps 215 and the guiding sliding grooves 226, when the wire-end plugging portion 214 is inserted into the board-end plugging cavity 225 of the board-end connector body 22, the guiding sliding grooves 226 can provide a track for the guiding steps 215, thereby ensuring the position accuracy of the wire-end plugging portion 214 and improving the installation efficiency and accuracy.

[0076] In some embodiments, a first guiding step and a second guiding step are respectively provided on both sides of the wire-end plugging portion 214, the first guiding step and the second guiding step are respectively located on the left and right sides of the wire-end plugging portion 214, and the left-right direction of the wire-end plugging portion 214 is the same as the left-right direction of the wire-end connector body 21; first guiding sliding grooves and second guiding sliding grooves are respectively provided on both side walls of the board-end connector body 22, the first guiding sliding grooves and the second guiding sliding grooves are arranged on the left and right sides of the board-end connector body 22, and the left-right direction of the board-end connector body 22 is also the same as the left-right direction of the wire-end connector body 21; moreover, the slot widths of the first guiding sliding groove and the second guiding sliding groove are different, the first guiding step is in fit connection with the first guiding sliding groove, and the second guiding step is adapted to the second guiding sliding groove, that is, the thicknesses of the first guiding step and the second guiding step in the front-back direction of the wire-end plugging portion 214 are different, and the front-back direction of the wire-end plugging portion 214 refers to the direction perpendicular to the air flow direction and parallel to the board 1; the above setting can play an anti-fooling role in the installation position of the wire-end plugging portion 214 or the board-end connector body 22.

[0077] In some embodiments, avoiding grooves 216 are provided on both sides of the wire-end insertion part 214, and the guiding step 215 protrudes from the wire-end insertion part 214 into the avoiding groove 216. That is to say, on the left and right sides of the wire-end insertion part 214, not only the guiding step 215 is provided, but also there is a spaced arrangement between the left and right sides of the wire-end insertion part 214 and the structure on the side of the wire-end connector body 21 close to the input connection end 211. Such a setting is to divide the wire-end insertion part 214 into a plug-in part, which is convenient for assembly with the board-end connector body 22. Further, the height of the guiding step 215 along the installation direction of the wire-end connector body 21 is less than the height of the avoiding groove 216 along the installation direction of the wire-end connector body 21. That is to say, when the wire-end insertion part 214 moves towards the board-end connector body 22, the avoiding groove 216 first cooperates with the guiding sliding groove 226, and then as the wire-end insertion part 214 continues to be pushed, the guiding step 215 enters the guiding sliding groove 226 and slides along the guiding sliding groove 226. With the above setting, after the wire-end insertion part 214 and the board-end connector body 22 are assembled, the bottom position of the board-end connector body 22 located in the guiding sliding groove 226 can enter the avoiding groove 216, further improving the limit of the board-end connector body 22 and the wire-end connector body 21 in the left-right direction. More specifically, the groove width of the guiding sliding groove 226 is less than the width of the two side walls of the board-end connector body 22, and limiting edges 2174 are formed on both sides of the guiding sliding groove 226, and the limiting edges 2174 cooperate with the side part of the wire-end insertion part 214 for limiting.

[0078] In some embodiments, an introducing arc part is provided at one end of the guiding step 215 close to the board-end connector body 22, and arc chamfers 2261 are provided on both sides at one end of the guiding sliding groove 226 close to the guiding step 215; the arc chamfers 2261 are used for guiding the introducing arc part when the guiding step 215 moves towards the guiding sliding groove 226, ensuring that the wire-end insertion part 214 can be smoothly inserted into the board-end connector body 22 and improving the assembly efficiency.

[0079] In some embodiments, please refer to Figure 10 , a wire-end stop surface 2141 is provided at the bottom of the wire-end insertion part 214, and the gold finger 213 protrudes from the wire-end stop surface 2141, that is, the boss where the gold finger 213 is located is on the wire-end stop surface 2141. A board-end stop surface 227 is provided inside the board-end connector body 22, and the board-end slot 223 is opened on the board-end stop surface 227; when the wire-end stop surface 2141 is in contact with the board-end stop surface 227, the slot terminal 224 is conducted with the gold finger 213. Through the settings of the wire-end stop surface 2141 and the board-end stop surface 227, the limit of the moving extreme positions of the wire-end insertion part 214 and the board-end connector body 22 can be restricted, avoiding damage to the gold finger 213 or the slot terminal 224 caused by the wire-end insertion part 214 being inserted into the board-end connector body 22 with too large a size.

[0080] In some embodiments, an elastic member 217 is provided on one of the wire-end connector body 21 and the board-end connector body 22, and a latch 228 is provided on the other. A locking portion 2171 that cooperates with the latch 228 is provided on the elastic member 217. Specifically, by providing the elastic member 217, when the wire-end connector body 21 and the board-end connector body 22 are assembled, the elastic member 217 undergoes elastic deformation until the locking portion 2171 on the elastic member 217 cooperates with the latch 228. Assembling in the manner of the elastic member 217 and the latch 228 has high disassembly and assembly efficiency and is convenient for installation. Further, the latch 228 is provided on the board-end connector body 22. The latch 228 can be a locking hole, and the locking portion 2171 can be a locking boss. The sizes of the locking hole and the locking boss are adapted to each other.

[0081] In some embodiments, an unlocking member is further included, which is used to drive the elastic member 217 to move to unlock the latch 228 and the locking portion 2171. The unlocking member is provided on the wire-end connector body 21 and is connected to the elastic member 217. By providing the unlocking member connected to the elastic member 217, and using the driving effect of the unlocking member on the elastic member 217, the locking portion 2171 on the elastic member 217 is separated from the latch 228 to complete unlocking. By providing the unlocking member, it is applicable to the case where the installation space is small and manual unlocking is not possible. For the convenience of unlocking, both the elastic member 217 and the unlocking member are provided on the wire-end connector body 21. Of course, when the space permits, the elastic member 217 can also be manually driven to unlock.

[0082] In some embodiments, the elastic member 217 is a spring piece. One end of the elastic member 217 is located on the wire-end connector body 21, and the other end is connected to the unlocking member. Specifically, the elastic member 217 is installed on the front side or the rear side of the wire-end connector body 21. The bottom of the elastic member 217 is provided on the wire-end connector body 21, and there is a deformation space between the top and the wire-end connector body 21. When the wire-end connector body 21 moves towards the board-end connector body 22, the elastic member 217 will move towards the direction close to the wire-end connector body 21 and enter the board-end insertion cavity 225 of the wire-end connector body 21. As the elastic member 217 is under the action of the front wall or the rear wall of the wire-end connector body 21, it undergoes elastic deformation. When the position of the locking portion 2171 moves to the position of the latch 228, the locking portion 2171 is engaged with the latch 228. At this time, under the action of its own elastic force, the elastic member 217 firmly restricts the latch 228 on the locking portion 2171. At this time, the wire-end connector body 21 just completes the assembly with the board-end connector body 22, that is, the gold finger 213 just cooperates and connects with the socket terminal 224.

[0083] In some embodiments, the unlocking component is a drawstring, and a drawstring channel 218 is also provided on the line end connector body 21. After the drawstring passes through the drawstring channel 218 and bypasses the drawstring connecting hole, it is passed back into the drawstring channel 218; the drawstring channel 218 is located at the top of the line end connector body 21 and is provided close to the elastic component 217; specifically, the drawstring passes through the drawstring channel 218, one end of the drawstring is a pulling end, and the other end is a connecting end, and the pulling end of the drawstring is located at the upper part of the line end connector body 21, which is convenient for manually pulling the drawstring, and the connecting end of the drawstring is connected to the elastic component 217, and the connecting part of the drawstring can be connected to the top of the elastic component 217. By pulling the drawstring, the elastic component 217 will be driven to move in a direction close to the line end connector body 21, thereby driving the lock buckle 228 to separate from the locking part 2171, completing the unlocking process of the elastic component 217.

[0084] In some embodiments, please refer to Figure 11 A drawstring connection hole is provided at the top of the elastic component 217, the drawstring is inserted into the drawstring connection hole, and the drawstring can extend to the side of the line-end connector body 21 away from the board-end connector body 22, which is convenient for manual pulling of the drawstring; the drawstring should have a certain hardness, which is not only convenient for observation from the drawstring channel 218, but also can prevent the drawstring from sticking to the line-end connector body 21, which is conducive to manual operation of the drawstring.

[0085] In some embodiments, locking buckles 228 are provided on both the front and rear sides of the board-end connector body 22, that is, the board-end connector body 22 can be a symmetrical structure, which is convenient for processing, and the installation direction between the board-end connector body 22 and the board card 1 can be unrestricted, thereby improving assembly efficiency.

[0086] In some embodiments, a plurality of connecting legs 2172 are provided on one side of the elastic member 217 close to the board-end connector body 22. For example, the number of connections can be two. By using the connecting legs 2172 to connect with the board-end connector body 22, the deformation of the elastic piece is easier and the assembly is convenient; the connecting legs 2172 are arc-shaped and located on the wire-end connector body 21. By using the arc-shaped connecting legs 2172, a deformation space can be formed between the elastic member 217 and the wire-end connector body 21; the middle part of the side of the elastic member 217 facing away from the board-end connector body 22 is connected to the unlocking member, that is, a strap connecting edge 2173 is provided at the middle position of the top of the elastic member 217, and a strap connecting hole is provided on the strap connecting edge 2173. Setting the strap connecting hole at the middle position of the top of the elastic member 217 can ensure the stability of the elastic member 217 during unlocking; specifically, the number of locking portions 2171 and the number of latches 228 can be multiple, for example, two, to improve the reliability of the locking effect; limiting edges 2174 are provided on both sides of the top of the elastic member 217; a limiting block 2175 cooperating with the limiting edge 2174 is also provided on the wire-end connector body 21. Specifically, the limiting block 2175 is located outside the limiting edge 2174. The setting of the limiting block 2175 and the limiting edge 2174 can make the deformation space between the elastic member 217 and the board-end connector body 22 not too large, which will neither affect the assembly of the wire-end connector body 21 nor affect the assembly of the wire-end connector body 21. At the same time, it can ensure the firm locking between the wire-end connector body 21 and the board-end connector body 22; further, an introduction inclined surface is provided on one side of the locking portion 2171 close to the board-end connector body 22, and a locking plane is provided on the other side. The latch 228 is clamped with the locking plane, and the introduction inclined surface can guide the elastic member 217 to elastically deform. Furthermore, in order to facilitate the driving of the elastic member 217 by the unlocking member, the strap connecting edge 2173 is bent toward the side away from the wire-end connector body 21, so that the distance between the strap connecting edge 2173 and the wire-end connector body 21 is increased. When the strap is pulled, the strap will drive the strap connecting edge 2173 to move, and then drive the elastic member 217 to move, completing the unlocking of the elastic member 217 and the latch 228.

[0087] In some embodiments, a board-end guiding edge 229 is further provided on the top of the board-end connector body 22. The board-end guiding edge 229 extends in an arc shape outward from the opening of the board-end insertion cavity 225 of the board-end connector body 22. When the wire-end insertion portion 214 of the wire-end connector body 21 moves toward the board-end insertion cavity 225, the board-end guiding edge 229 can play a guiding role to ensure that the wire-end insertion portion 214 is smoothly inserted into the board-end insertion cavity 225.

[0088] In some embodiments, an avoidance chamfer 219 is further provided on the wire-end connector body 21. On the one hand, the avoidance chamfer 219 can avoid the board-end connector body 22, and on the other hand, it can also prevent interference with the board card 1, so that the bottom of the side of the wire-end connector body 21 where the input connection end 211 is provided can be lower than the surface of the board card 1, reducing the height of the wire-end connector body 21 in the direction perpendicular to the board card 1, thereby saving space.

[0089] Specifically, in a specific embodiment, when installing the hard disk installation module, the board card 1 can be first assembled on the main board of the device body, and then the board-end connector body 22 is installed; alternatively, the board-end connector body 22 can be first installed on the board card 1, and then the board card 1 is installed on the main board of the device body; when connecting the board-end connector body 22 and the board card 1, first insert the board-end pins 222 of the board-end connector body 22 into the positioning holes, and then weld and fix the positioning holes and the board-end pins 222; select a regular wire-end connector body 21, insert the wire-end insertion part 214 of the wire-end connector body 21 into the board-end insertion cavity 225 of the board-end connector body 22 until the locking part 2171 of the elastic member 217 cooperates with the lock 228 on the board-end connector body 22; then install the hard disk 3 on the input connection end 211 of the wire-end connector body 21; when it is necessary to disassemble the wire-end connector body 21, manually pull the pull belt to drive the elastic member 217 to move, and the locking part 2171 is separated from the lock 228, and at this time, the wire-end connector body 21 can be pulled out of the board-end connector body 22 to complete the disassembly process.

[0090] In addition to the above hard disk installation module, the present invention also provides a chassis including the above hard disk installation module. The heat dissipation channel is located inside the chassis. Of course, the hard disk installation module is installed inside the chassis.
