[0019] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] The features of the terms "first" and "second" in the specification and claims of the present invention may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "plurality" means two or more. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally means that the objects connected before and after are in an "or" relationship.

[0022] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] E3 hard drives include E3.S hard drives and E3.L hard drives. Taking the E3.S hard drive as an example, the shape of the E3.S hard drive is similar to that of the U.2 hard drive, and traditional servers can more easily transition to the E3 form through compatible design. The E3.S has two thickness specifications of 7.5mm and 16.8mm, and can be installed vertically in a 2U server or horizontally in a 1U server. The thickness of the U.2 hard drive is 15mm. In a traditional 2U server, the maximum number of front U.2 hard drives is 24; the thickness of the E3.S / 2T is 16.8mm, and the number of E3.S / 2Ts that can be placed in a 2U server is 23. The E3.S / 1T can have up to 46 hot-swappable positions, and its density advantage is quite obvious.

[0024] In a 1U chassis, E3.S hard drives need to be placed horizontally. Ten 16.8mm E3.S hard drives can be placed in a 1U chassis, the same number as U.2 hard drives. Twenty 7.5mm E3.S hard drives can be placed in a 1U chassis, twice as many as U.2 hard drives. After PCIe5.0, the bandwidth, performance and electrical characteristics supported by U.2 and M.2 are difficult to meet the requirements. Switching to E3 is an inevitable trend.

[0025] To this end, an embodiment of the present invention provides a hard disk storage system including an E3 hard disk. Figure 1 The hard disk storage system of the present invention is described.

[0026] An embodiment of the present invention provides a hard disk storage system, such as Figure 1 As shown, it includes a first mainboard 11, a second mainboard 12, a backplane 20 and an E3 hard disk 50. The first mainboard 11 is connected to the backplane 20 via a first high-density connector, the second mainboard 12 is connected to the backplane 20 via a second high-density connector, and the E3 hard disk 50 is connected to the backplane 20 via a hard disk connector 40. The hard disk connector 40 is located between the first high-density connector and the second high-density connector.

[0027] The hard disk storage system includes two main boards, a first main board 11 and a second main board 12, wherein the main board integrates the main circuit system of the computer device. For example, electrical components such as a BIOS chip and an I / O control chip are installed on the main board. Optionally, the first main board 11 is the main control board, and the second main board 12 is the standby control board, and the standby control board is in standby mode when the main control board operates normally. Therefore, through the mutual cooperation of the first main board 11 and the second main board 12, when a failure occurs in the main control board, the system automatically switches to the standby control board to ensure the continuity and stability of the system; and in some cases, the first main board 11 and the second main board 12 can work in parallel to jointly process business and data to improve the overall performance of the system.

[0028] The first mainboard 11 is connected to the backplane 20 via a first high-density connector, and the second mainboard 12 is connected to the backplane 20 via a second high-density connector. The high-density connector has a large number of pins and has a high-density characteristic. Therefore, in a compact space, the high-density connector can realize the layout of multiple connection points, improve the connection efficiency and space utilization. Optionally, the first high-density connector and the second high-density connector adopt a contact probe structure, which can complete the operation without applying force during plugging and unplugging, simplifying the operation process. In addition, the mainboard and the backplane are connected by a high-density connector, which can have lower crosstalk and attenuation during signal transmission, thereby improving the stability and accuracy of the signal.

[0029] like Figure 1 As shown, the first high-density connector and the second high-density connector are located on the first side of the backplane 20, and the hard disk connector 40 is connected to the second side of the backplane 20, wherein the hard disk connector 40 is located between the first high-density connector and the second high-density connector, so that the connection position of the first high-density connector and the backplane 20, the connection position of the second high-density connector and the backplane 20, and the connection position of the hard disk connector 40 and the backplane 20 are staggered on the backplane 20, ensuring that the connection position of the first high-density connector and the second high-density connector on the backplane 20 will not interfere with the connection between the hard disk connector 40 and the backplane 20.

[0030] It can be understood that the number of E3 hard disks 50 in the hard disk storage system can be multiple, and multiple E3 hard disks 50 are stacked and arranged, and each E3 hard disk 50 is connected to the backplane 20 through a hard disk connector 40. Among them, the connection position of each hard disk connector 40 and the backplane 20 is located between two high-density connectors. In one embodiment, the connection positions of multiple hard disk connectors 40 and the backplane 20 are at the same height, thus, multiple hard disk connectors 40 are arranged in a single row. In another embodiment, the hard disk connectors 40 installed on adjacent E3 hard disks 50 are staggered, thus, multiple hard disk connectors 40 are arranged in two rows, three rows or more rows, and multiple hard disk connectors 40 located in the same row are at the same height, and hard disk connectors 40 located in different rows are at different heights, as long as the connection position of each hard disk connector 40 and the backplane 20 is ensured to be between the two high-density connectors.

[0031] The hard disk connector 40 is a 1C connector or a 2C connector. Among them, the 1C connector refers to a connector that complies with the SFF-TA-1002 standard and can support the x4 PCIe interface. It is flexible, supports multiple configurations and modular designs, and can maintain the robustness characteristics of the SFF-TA-1002 standard to ensure excellent signal integrity during high-speed data transmission. Optionally, the 1C connector is an EDSFF 1C connector, that is, a connector specification under the Enterprise and Data Center SSD Form Factor (EDSFF) standard, which can provide enterprises and data centers with higher capacity, scalability, performance and heat dissipation capabilities. Solid-state hard disk solutions. 2C connector refers to a connector that complies with the SFF-TA-1002 standard and can support the x8 PCIe interface. During installation, select a suitable hard disk connector 40 according to the specific interface form of the connection structure 51 on the E3 hard disk 50.

[0032] In the hard disk storage system provided by the embodiment of the present invention, the first main board 11 and the second main board 12 are respectively connected to the backplane 20 using a high-density connector, and the E3 hard disk 50 is connected to the backplane 20 via the hard disk connector 40. By arranging the hard disk connector 40 between the first high-density connector and the second high-density connector, the connection positions of the first high-density connector and the second high-density connector on the backplane 20 will not interfere with the hard disk connector 40, thereby ensuring that the E3 hard disk 50 and the main board can be installed on the backplane 20.

[0033] like Figure 1As shown, the backplane 20 has a first high-density connector male head 312 and a second high-density connector male head 322, the first mainboard 11 has a first high-density connector female head 311, and the second mainboard 12 has a second high-density connector female head 321. The first high-density connector male head 312 is docked with the first high-density connector female head 311, and the second high-density connector male head 322 is docked with the second high-density connector female head 321.

[0034] The first high-density connector male head 312 and the second high-density connector male head 322 are spaced apart along the same horizontal plane of the backplane 20. The first mainboard 11 and the second mainboard 12 are connected to the two high-density connector male heads in a one-to-one correspondence. Optionally, the first high-density connector male head 312 and the second high-density connector male head 322 have the same structure.

[0035] Among them, the structures of the first high-density connector and the second high-density connector can be the same or different. Among them, the first high-density connector includes four pairs of pins, which is suitable for applications that need to transmit four groups of differential signals or four independent signals. Alternatively, the first high-density connector includes six pairs of pins, which has more signal transmission capabilities and is suitable for scenarios where higher-density signal transmission is required, such as six groups of differential signals or six independent signals. Similarly, the second high-density connector includes four pairs of pins, which is suitable for applications that need to transmit four groups of differential signals or four independent signals. Alternatively, the second high-density connector includes six pairs of pins, which has more signal transmission capabilities and is suitable for scenarios where higher-density signal transmission is required, such as six groups of differential signals or six independent signals. Of course, the first high-density connector and the second high-density connector can also use high-density connectors with other numbers of pins as needed.

[0036] Optionally, the first high-density connector female head 311 is connected to the first mainboard 11 by a press-fit process, so that the high-speed signal of the first mainboard 11 is transmitted to the backplane 20 through the cooperation of the first high-density connector female head 311 and the first high-density connector male head 312. Similarly, the second high-density connector female head 321 is connected to the second mainboard 12 by a press-fit process, so that the high-speed signal of the second mainboard 12 is transmitted to the backplane 20 through the cooperation of the second high-density connector female head 321 and the second high-density connector male head 322.

[0037] On the basis of the above embodiment, the first high-density connector male head 312 is crimped and connected to the first high-density connector female head 311 , and the second high-density connector male head is crimped and connected to the second high-density connector female head 321 .

[0038] In an optional embodiment, the first high-density connector male head 312 and the second high-density connector male head 322 are pins, the first high-density connector female head 311 and the second high-density connector female head 321 are jacks, and the pins are inserted into the jacks to achieve electrical connection between the high-density connector male head and the high-density connector female head. In another optional embodiment, the first high-density connector male head 312 and the second high-density connector male head 322 are jacks, and the first high-density connector female head 311 and the second high-density connector female head 321 are pins. Optionally, the pins are hard pins or elastically deformable pins, and the jacks are metallized holes. After the pins are inserted into the jacks, a close contact point is formed between the pins and the metallized holes, and electrical interconnection is achieved by mechanical connection.

[0039] In the hard disk storage system provided by the embodiment of the present invention, the first high-density connector male head 312 and the first high-density connector female head 311, as well as the second high-density connector female head 321 and the second high-density connector male head 322 are connected by crimping, thereby achieving electrical connection through the mechanical cooperation of the high-density connector male head and the high-density connector female head. Compared with the traditional welding method, the crimping connection method can meet the requirements of electronic products for consistency and high density.

[0040] In addition, the structures of the first high-density connector male head 312 and the second high-density connector male head 322 may also be different. For example, one of the first high-density connector male head 312 and the second high-density connector male head 322 is a socket and the other is a pin; correspondingly, one of the first high-density connector female head 311 and the second high-density connector female head 321 is a socket and the other is a socket, as long as the first high-density connector male head 312 and the first high-density connector female head 311 can be adapted, the second high-density connector male head 322 and the second high-density connector female head 321 can be adapted.

[0041] Optionally, the first high-density connector male head 312 and the second high-density connector male head 322 are both perpendicular to the backplane 20. Figure 1 As shown, the backplane 20 is a vertical plate, which is vertically arranged between the mainboard and the E3 hard disk 50 .

[0042] In addition, the backplane 20 can also be an L-shaped plate, including a horizontal plate and a vertical plate. The first mainboard 11 and the second mainboard 12 are both connected to the vertical plate, and the E3 hard disk 50 is connected to the other side of the vertical plate. The horizontal plate is used to be fixed in the box structure of the server.

[0043] The first main board 11 and the second main board 12 are arranged in parallel, and correspondingly, the first high-density connector female head 311 and the second high-density connector female head 321 are arranged in parallel. The first high-density connector male head 312 and the second high-density connector male head 322 are arranged perpendicular to the surface of the backplane 20, so that the first high-density connector male head 312 and the second high-density connector male head 322 are both arranged vertically on the backplane 20, and the second high-density connector male head 322 is arranged vertically on the backplane 20 to facilitate docking with the second high-density connector female head 321. In the case of the first high-density connector female head 311 and the first high-density connector male head 312 being crimped and connected, the first high-density connector male head 312 arranged vertically on the backplane 20 is convenient for crimping and mating with the first high-density connector female head 311, and the second high-density connector male head 322 arranged vertically on the backplane 20 is convenient for crimping and mating with the second high-density connector female head 321.

[0044] The E3 hard disk 50 has a connection structure 51 , a first end of the hard disk connector 40 is connected to the backplane 20 , and a second end of the hard disk connector 40 is connected to the connection structure 51 .

[0045] The connection structure 51 is used to connect to the hard disk connector 40. In the case where there are multiple E3 hard disks 50, each E3 hard disk 50 is provided with a connection structure 51, and multiple connection structures 51 are arranged at intervals along the length direction of the backplane 20, and each connection structure 51 can be connected to a hard disk connector 40.

[0046] During the installation process, multiple E3 hard disks 50 are arranged in a one-to-one correspondence with multiple hard disk connectors 40. The number of connection structures 51 is the same as the number of hard disk connectors 40. The connection positions of different hard disk connectors 40 and the backplane 20 are arranged in an up-down staggered manner to facilitate the installation of the hard disk connectors 40. Alternatively, the connection positions of different hard disk connectors 40 and the backplane 20 are arranged along the same vertical line of the backplane 20.

[0047] When the connection positions of multiple hard disk connectors 40 and the backplane 20 are arranged in multiple rows in an up-down staggered manner. For example, the connection positions of multiple hard disk connectors 40 and the backplane 20 are arranged in two rows in an up-down staggered manner. At this time, when installing the first E3 hard disk 50, the connection structure 51 of the E3 hard disk 50 can be connected to the end of the hard disk connector 40 in the top row; when installing the second E3 hard disk 50, the connection structure 51 of the second E3 hard disk 50 can be connected to the end of the hard disk connector 40 located in the second row; the second E3 hard disk 50 here refers to the E3 hard disk 50 adjacent to the first E3 hard disk 50. The hard disk connector 40 located in the second row refers to the hard disk connector 40 adjacent to the hard disk connector 40 located in the top row and located at the first position in the second row. By analogy, when installing the third E3 hard disk 50, the connection structure 51 of the third E3 hard disk 50 can be connected to the end of the hard disk connector 40 located in the second position in the top row. When installing the fourth E3 hard disk 50, the connection structure 51 of the fourth E3 hard disk 50 can be connected to the end of the hard disk connector 40 located at the second position in the second row. This process can be deduced by analogy until all E3 hard disks 50 are connected to the hard disk connectors 40.

[0048] Preferably, the connection structures 51 are arranged in the same manner and position on multiple E3 hard disks 50. During installation, there is no need to distinguish the E3 hard disks 50, which can avoid errors in the process of installing multiple E3 hard disks 50 and improve the accuracy and efficiency of assembly.

[0049] In the case where there are multiple E3 hard disks 50, multiple E3 hard disks 50 are arranged along the length direction of the backplane 20, and the backplane 20 reserves space for setting heat dissipation holes in the area between two adjacent E3 hard disks 50 to achieve heat dissipation of the mainboard. Specifically, in the case where there are multiple E3 hard disks 50, multiple hard disk connectors 40 are correspondingly arranged. For the convenience of installation, the hard disk connectors 40 installed on two adjacent E3 hard disks 50 are arranged in an up-and-down staggered manner, thereby forming multiple rows of hard disk connectors 40 along the height direction of the backplane 20. Among them, the setting heights of each hard disk connector 40 in each row are the same. Along the height direction of the backplane 20, the size of the overlapping part of the upper and lower adjacent rows of hard disk connectors 40 can be made smaller than half of the height of a single hard disk connector 40. Of course, the size of the overlapping part of the upper and lower adjacent rows of hard disk connectors 40 can be made half of the height of a single hard disk connector 40, or the size of the overlapping part of the upper and lower adjacent rows of hard disk connectors 40 can be made slightly larger than half of the height of a single hard disk connector 40, or other values, which are determined according to actual conditions and will not be repeated here.

[0050] By staggering the upper and lower adjacent rows of hard disk connectors 40, the height dimension occupied by the two rows of hard disk connectors 40 in the height direction of the back plate 20 can be further reduced, and the two adjacent rows of hard disk connectors 40 can be further partially overlapped in the height direction of the back plate 20, further reducing the height dimension occupied by the two rows of hard disk connectors 40 in the height direction of the back plate 20, so as to achieve the installation of more hard disk connectors 40 without changing the height of the back plate 20, while ensuring the spacing distance between the two adjacent hard disk connectors 40, and reserving space for setting heat dissipation holes.

[0051] It should be noted that in this specific embodiment, the upper and lower adjacent rows of hard disk connectors 40 have overlapping parts in the height direction of the back plate 20, and the upper and lower adjacent rows of hard disk connectors 40 are staggered. This arrangement will squeeze the space used to set the heat dissipation holes. Therefore, the overlapping dimensions of the upper and lower adjacent rows of hard disk connectors 40 in the height direction of the back plate 20 need to be strictly calculated and determined based on actual conditions.

[0052] In a specific embodiment, the spacing dimensions between the upper and lower adjacent rows of hard disk connectors 40 are the same. Among them, the spacing dimension between the adjacent hard disk connectors 40 in the upper row is equal to the spacing dimension between the adjacent hard disk connectors 40 in the lower row. The backplane 20 is provided with heat dissipation holes in the area between the adjacent hard disk connectors 40 so that the first motherboard 11 and the second motherboard 12 can fully dissipate heat. Therefore, the spacing dimension between the adjacent hard disk connectors 40 cannot be too small, which is determined according to actual conditions and will not be elaborated here.

[0053] In this specific embodiment, the spacing between two adjacent hard disk connectors 40 in each row is the same, so that the hard disk connectors 40 can be neatly and evenly distributed, and the spacing between two adjacent hard disk connectors 40 is ensured to be the same, which facilitates the arrangement of evenly distributed heat dissipation holes, so that each part of the first mainboard 11 and the second mainboard 12 can dissipate heat evenly. At the same time, during the installation of the E3 hard disk 50, the spacing between two adjacent E3 hard disks 50 can be made the same, thereby improving the neatness of the installation process of the E3 hard disk 50.

[0054] In a specific embodiment, the offset size of the two adjacent rows of hard disk connectors 40 is half of the distance between the two adjacent hard disk connectors 40; the hard disk connector 40 in the lower row is just located in the middle position between the two adjacent hard disk connectors 40 in the upper row. In the actual installation process of the E3 hard disk 50, the spacing size between the two adjacent hard disk connectors 40 can be ensured to be the same, which facilitates the setting of evenly distributed heat dissipation holes to uniformly dissipate heat from various parts of the controller; at the same time, in the installation process of the E3 hard disk 50, the spacing size between the two adjacent E3 hard disks 50 can be made the same, thereby improving the integrity of the installation process of the E3 hard disk 50.

[0055] The heat dissipation holes are arranged between two adjacent hard disk connectors 40. For example, two rows of hard disk connectors 40 are arranged on the back panel 20, and the two rows of hard disk connectors 40 are arranged in the middle, and heat dissipation holes are arranged between two adjacent hard disk connectors 40 in the two rows of hard disk connectors 40, and the heat dissipation holes between two adjacent hard disk connectors 40 in the upper row of hard disk connectors 40 can be used to dissipate heat for the first mainboard 11, and the heat dissipation holes 6 between two adjacent hard disk connectors 40 in the lower row of hard disk connectors 40 can be used to dissipate heat for the second mainboard 12, so that the first mainboard 11 and the second mainboard 12 can achieve uniform heat dissipation.

[0056] It should be noted that when the number of hard disk connectors 40 is other values, the size of the hard disk connector 40 in the length direction of the back panel 20 can be shortened so that two rows of hard disk connectors 40 can be set at the same height position of the back panel 20. Of course, multiple hard disk connectors 40 can also be stacked and arranged, which depends on the actual situation.

[0057] The back plate 20 is provided with heat dissipation holes that penetrate the thickness direction of the back plate 20, and the heat dissipation holes are used to dissipate heat for the first main board 11 and the second main board 12. In the present specific embodiment, since the hard disk connector 40 is arranged at the middle position in the height direction of the back plate 20, the heat dissipation holes are also arranged at the middle position in the height direction of the back plate 20, so that the first main board 11 and the second main board 12 arranged up and down can dissipate heat evenly.

[0058] Specifically, the shapes and sizes of the heat dissipation holes are the same. For example, the heat dissipation holes are square holes, oval holes, circular holes, polygonal holes, or other shapes that meet the requirements, which are determined according to the actual situation and will not be described here. Of course, the shapes and sizes of the heat dissipation holes can also be only partially the same. For example, some heat dissipation holes are circular holes, and other heat dissipation holes are square holes or oval holes. For another example, some heat dissipation holes are circular holes with an aperture of R1, and other heat dissipation holes are circular holes with an aperture of R2, and R1 and R2 are different in size.

[0059] Optionally, the second end of the hard disk connector 40 and the connection structure 51 are located at the same horizontal plane, which facilitates the connection of the hard disk connector 40 and the E3 hard disk 50. Each E3 hard disk 50 is provided with a connection structure 51. For multiple E3 hard disks 50, multiple connection structures 51 are arranged in a one-to-one correspondence with multiple hard disk connectors 40, and the relatively arranged connection structures 51 and the second end of the hard disk connector 40 are located at the same horizontal plane. It can be understood that the connection structure 51 and the second end of the hard disk connector 40 can also be located at different horizontal planes. In this case, a transfer structure can be set at the end of the E3 hard disk 50, and the second end of the hard disk connector 40 and the connection structure 51 are located at the same horizontal plane through the transfer structure. In the case of multiple E3 hard disks 50, the connection structures 51 of multiple E3 hard disks 50 can only partially be at the same horizontal plane with the second end of the corresponding hard disk connector 40, and the other connection structures 51 can make the second end of the hard disk connector 40 and the connection structure 51 at the same horizontal plane through the transfer structure.

[0060] In one embodiment, the hard disk connector 40 is bent, and includes a first connection end, a middle section, and a second connection section connected in sequence. The first connection section is connected to the backplane 20, the second connection section is connected to the E3 hard disk 50, the middle section is at an obtuse angle to the first connection section, and the second connection section is at an obtuse angle to the middle section. At this time, the first connection section is vertically arranged with the backplane 20, and can be directly connected with the backplane 20, and the second connection section and the connection structure 51 are in the same horizontal plane, which is convenient for direct docking.

[0061] Specifically, the connection structure 51 is a gold finger. It should be noted that, when there are multiple E3 hard disks 50, the connection structures 51 of the multiple E3 hard disks 50 are all gold fingers, or the connection structures 51 of some E3 hard disks 50 are gold fingers.

[0062] Specifically, a gold finger is provided at the end of the E3 hard disk 50 as a connection structure 51, and the gold finger includes a plurality of golden conductive contacts. The gold finger is formed by coating a layer of gold on the copper clad plate through an electroplating process, because gold has a strong anti-oxidation property and can protect the internal circuit from corrosion, and it also has a strong electrical conductivity and will not cause signal loss. At the same time, gold has a very strong ductility and can make the contact area between the contacts larger under appropriate pressure, thereby reducing the contact resistance and improving the signal transmission efficiency. In the embodiment of the present invention, the gold finger meets the SFF-TA-1002 1C specification, and the use of the gold finger can ensure better signal quality between the E3 hard disk 50 and the backplane 20.

[0063] In combination with the previous embodiment, the gold finger is located at the same horizontal plane as the end of the hard disk connector 40. When the hard disk connector 40 is bent and includes a first connection end, a middle section and a second connection section connected in sequence, the second connection section and the gold finger are at the same horizontal plane, which is convenient for direct docking.

[0064] In a specific embodiment, the hard disk connector 40 includes a first connecting section, a middle section, and a second connecting section connected in sequence. The first connecting section is connected to the backplane 20, and the second connecting section is connected to the E3 hard disk 50. The middle section forms an obtuse angle with the first connecting section, and the second connecting section forms an obtuse angle with the middle section.

[0065] The end of the first connecting section away from the middle section and the end of the second connecting section away from the middle section respectively have connectors, and the connectors are pin structures or socket structures. The connector at the end of the first connecting section is used to connect to the backplane 20, and the connector at the end of the second connecting section is used to connect to the E3 hard disk 50.

[0066] The middle section may be a flexible connecting line. For example, the middle section includes a flexible main body and rigid structures disposed at both ends of the flexible main body, wherein one rigid structure is connected to the first connecting section, and the other rigid structure is connected to the second connecting section, and the rigid structure is used to improve the connection strength between the first connecting section and the second connecting section. Correspondingly, the angle between the first connecting section and the middle section refers to the angle between the first connecting section and the length direction of the flexible main body; the angle between the second connecting section and the middle section refers to the angle between the second connecting section and the length direction of the flexible main body.

[0067] In an optional embodiment, both the first connecting section and the second connecting section are connectors, and reinforcing ribs are respectively provided at both ends of the middle section. The reinforcing ribs are used to improve the connection strength between the connector and the middle section, thereby improving the bending resistance and durability of the entire hard disk connector. Correspondingly, the angle between the first connecting section and the middle section refers to the angle between the connector forming the first connecting section and the extension direction of the reinforcing rib; the angle between the second connecting section and the middle section refers to the angle between the connector forming the second connecting section and the extension direction of the reinforcing rib. In another optional embodiment, hard rings are respectively provided at the connection between the middle section and the first connecting section and at the connection between the middle section and the second connecting section, and the hard rings are used to prevent the connection from breaking.

[0068] The hard disk connector 40 is bent, and has a first connection section, a middle section, and a second connection section that are sequentially connected. It should be noted that the first connection section and the second connection section extend in a horizontal direction, and the first connection section and the second connection section are arranged in parallel, so as to facilitate connecting the first connection section to the upright back panel 20 and to facilitate connecting the second connection section to the E3 hard disk 50.

[0069] It should be noted that the hard disk connector 40 may include other connecting segments in addition to the first connecting segment, the middle segment and the second connecting segment, as long as the first connecting segment and the second connecting segment are arranged in parallel and extend in the horizontal direction.

[0070] In a specific embodiment, the hard disk connector 40 is connected to the backplane 20 by crimping. The connection position between the hard disk connector 40 and the backplane 20 is staggered with the connection position between the high-density connector and the backplane 20, and the hard disk connector 40 can be connected to the backplane 20 by crimping.

[0071] Optionally, the interface form of the first connection section and the second connection section are the same, and the interface opening direction of the first connection section is the same as the interface opening direction of the second connection section. During installation, it is not necessary to distinguish between the first connection section and the second connection section, and one of the connection sections can be directly connected to the backplane 20, and the other connection section can be connected to the E3 hard disk 50. Therefore, by setting the interface of the first connection section and the second connection to the same form, it is avoided that distinguishing between the first connection section and the second connection section during installation affects the installation efficiency.

[0072] Specifically, the ends of the first connection section and the second connection section are both provided with electrical jacks, and the backplane 20 and the E3 hard disk 50 are both provided with electrical pins, which are inserted into the corresponding electrical jacks to achieve the connection between the first connection section and the backplane 20 and the connection between the second connection section and the E3 hard disk 50. Alternatively, the ends of the first connection section and the second connection section are both provided with electrical pins, and the backplane 20 and the E3 hard disk 50 are both provided with electrical jacks. The crimping connection between the hard disk connector 40 and the backplane 20 and the crimping connection between the hard disk connector 40 and the E3 hard disk 50 are achieved by plugging the electrical jacks and the electrical pins.

[0073] In addition, the end interface of the first connection segment and the end interface of the second connection segment may also be in different forms. For example, the end interface of the first connection segment is an electrical pin, and the end interface of the second connection segment is an electrical socket. Alternatively, the end interface of the first connection segment is an electrical socket, and the end interface of the second connection segment is an electrical pin. By setting different forms of end interfaces, the first connection segment and the second connection segment can be distinguished. During installation, the first connection segment and the second connection segment are distinguished according to the different forms of end interfaces set, and the first connection segment is connected to the backplane 20 and the second connection segment is connected to the E3 hard disk 50.

[0074] The hard disk storage system provided by the embodiment of the present invention improves the convenience of installation by crimping the first high-density male connector with the first high-density female connector, and the second high-density male connector with the second high-density female connector. At the same time, the signal communication quality between the first main board 11 and the second main board 12 and the backplane 20 can be improved by crimping.

[0075] In order to improve the stability of the connection between the hard disk connector 40 and the back plate 20 , the hard disk connector 40 is provided with a fixing hole, and a fastener is passed through the fixing hole to fix the back plate 20 and the hard disk connector 40 together.

[0076] Optionally, the fixing hole is a screw hole, and the fastener is a screw, and the screw passes through the screw hole to connect the back plate 20 to the hard disk connector 40. For example, the end interface of the hard disk connector 40 is an electrical pin, and the outer shell of the electrical pin has a lug, and the lug is provided with a fixing hole. When the hard disk connector 40 is connected to the back plate 20, the electrical pin is inserted into the electrical jack, and at the same time, the outer shell of the electrical pin is connected to the back plate 20 through the fixing hole by screws or other fasteners, so that the back plate 20 and the hard disk connector 40 are stably connected together to prevent external vibration from causing the connection between the back plate 20 and the hard disk connector 40 to become loose.

[0077] That is, a fixing hole is provided outside the interface of one end of the first connecting section away from the middle section, so as to enhance the stability of the connection between the first connecting section and the back plate 20 by means of the fixing hole.

[0078] Optionally, there are multiple fixing holes, and the multiple fixing holes are evenly arranged along the circumference of the hard disk connector 40, and multiple fasteners are installed in the corresponding fixing holes one by one, so that the hard disk connector 40 is fastened to the back plate 20, and the uniformity of the distribution of the connecting force between the hard disk connector 40 and the back plate 20 can be improved. For example, the end shell of the hard disk connector 40 is provided with an outer edge in the circumference, and multiple fixing holes are arranged at intervals along the outer edge. Alternatively, the end of the hard disk connector 40 has multiple ears, and each ear is provided with a fixing hole.

[0079] The hard disk storage system provided by the embodiment of the present invention improves the stability of the connection between the backplane 20 and the hard disk connector 40 by adding a fixing hole on the hard disk connector 40 and fixing the backplane 20 with the hard disk connector 40 by means of a fastener penetrating the fixing hole. At the same time, the fastening effect of the fastener can also keep the signal transmission quality between the hard disk connector 40 and the backplane 20 stable, avoiding the loose connection between the two due to external vibration and affecting the signal transmission quality.

[0080] As described above, the end of the E3 hard disk 50 connected to the hard disk connector 40 is a gold finger-shaped connection structure 51, and correspondingly, the end of the hard disk connector 40 connected to the E3 hard disk 50 is provided with a metal spring. The metal spring and the crimping pin inside the hard disk connector 40 are an integrated structure.

[0081] Specifically, one end of the hard disk connector 40 connected to the E3 hard disk 50 is the second connecting section. In order to adapt to the gold finger at the end of the E3 hard disk 50, a metal spring adapted to the gold finger is set at the end interface of the second connecting section. The metal spring and the crimping pin inside the hard disk connector 40 are an integrated structure to improve the signal quality.

[0082] If the metal spring and the crimping pin are separately provided, the connection between the metal spring and the crimping pin is easy to loosen or the signal transmission quality is affected due to improper assembly. When there are a large number of E3 hard disks 50, it is difficult to find the fault location and it is inconvenient to repair. In the hard disk storage system provided by the embodiment of the present invention, the metal spring provided at the end of the hard disk connector 40 and the crimping pin inside the hard disk connector 40 are an integrated structure. Compared with the method of separately providing the metal spring and the crimping pin, it can avoid signal transmission interruption and improve the stability and effectiveness of signal transmission.

[0083] The connection end of the hard disk connector 40 and the E3 hard disk 50 meets the SFF-TA-1002 specification definition. Among them, the E3 hard disk 50 is a hard disk that meets the E3.S and E3.L of the SFF-TA-1002 specification definition.

[0084] The hard disk storage system provided by the embodiment of the present invention includes a first mainboard 11, a second mainboard 12, a backplane 20 and an E3 hard disk 50. The first mainboard 11 is provided with a first high-density connector female head 311, which cooperates with a first high-density connector male head 312 provided on the backplane 20; the second mainboard 12 is provided with a second high-density connector female head 321, which cooperates with a second high-density connector male head 322 provided on the backplane 20. The connection position of the hard disk connector 40 and the backplane 20 is located between the first high-density connector male head 312 and the second high-density connector male head 322, so that the high-density connector and the hard disk connector are staggered to avoid interference when connected to the backplane 20.

[0085] Specifically, the hard disk connector 40 is bent, including a first connection section, a middle section, and a second connection section connected in sequence, the first connection section is connected to the backplane 20, and the second connection section is connected to the E3 hard disk 50. The first connection section is parallel to the second connection section, and the second connection section and the connection structure 51 provided on the E3 hard disk 50 are located in the same horizontal plane to facilitate docking. Optionally, the connection structure 51 is a gold finger, and a metal spring that cooperates with the gold finger is provided at one end of the second connection section away from the middle section, and the metal spring is integrally provided with the crimping pin inside the hard disk connector 40.

[0086] Among them, the hard disk connector 40 and the E3 hard disk 50 are connected by crimping, and the first mainboard 11 and the backplane 20 as well as the second mainboard 12 and the backplane 20 are connected by crimping respectively, which improves the convenience of installation and the communication quality.
