[0028] Through the above, by setting the cable connection component connected with the ground lines of the communication buses in the server, the classification and collection of the to-be-grounded components in the server to the first connection end are realized, which on the one hand saves the number of port occupation of the first connection end, and on the other hand ensures the neatness of the internal space of the server, and facilitates the subsequent maintenance operation of the grounding device.

When installed, the connecting cables connected with the fixing components are respectively connected to the first fixed holes on the fixing frame and the side wall cross bar, so as to realize that all movable structural components are actively grounded with the server case. The second fixed hole is connected with the first connecting end, so that the metal fixing components can be concentrated on the first connecting end, and the impedance difference is reduced.

[0044] Through the above, by setting the support component, the plurality of third connection ends and fourth connection ends are integrated on the same support component, and the structure of the internal grounding device of the server is simplified.

[0045] As an optional embodiment, the support component is fixed on the side wall of the server.

[0046] As an optional embodiment, the server device further comprises a state monitor connected with the first connection end and the second connection end respectively.

[0047] Optionally, in the embodiment, the state monitor is a device for monitoring the in-place state of each connection end in the grounding device, and the state monitor can be but is not limited to a baseboard management controller (BMC) provided in the server device. When an electromagnetic emission test of the server is abnormal, it is quickly determined whether the problem is a grounding problem, and the speed of rectification is accelerated. When the electromagnetic compatibility test is abnormal, the grounding problem is first checked. Since the new structure and the grounding scheme of the cable are adopted, the location of the grounding problem can be quickly viewed, and the grounding problem can be quickly checked. The rectification strategy and countermeasures are formulated. Due to the convenience of the structure and the cable scheme, after the grounding problem is quickly checked and the grounding problem is eliminated, other countermeasures are started to formulate rectification strategies. Finally, the rectification is completed, and the electromagnetic compatibility performance is met.

[0048] At present, there are many movable metal structural parts (fixed parts) in the server, such as PCIE supports, case covers, dust covers, etc. In order to facilitate the modification of the server, such structural parts are generally designed to be movable or detachable in the related art. They are all connected to the main body of the case by screws, etc., and finally connected to the ground line of the power supply system through the ground pin of the power supply. Although they are all connected to the main body of the case by screws, etc., and finally connected to the ground line through the ground pin of the power supply, due to their movable characteristics, it is easy to cause impedance difference between each structural part and the ground pin of the power supply. Since the structural part also serves as a carrier of the PCIE part, for example, on the PCIE structural part, a network card, a graphics card, a hard disk, etc. PCIE equipment are usually installed. When these PCIE equipment are powered on and work, due to the resistance difference between the structural parts of different equipment and the ground of the power supply, strong common mode interference emission is generated, causing electromagnetic radiation emission to exceed the standard and static electricity problems.

[0049] In addition, there are many internal cables (connection cables) in the current server, including not only low-speed signal lines such as DC power supply lines, but also a large number of high-speed signal lines such as MCIO. In the related art, whether it is a low-speed line or a high-speed line, a ground wire is generally integrated, and the ground wire is connected to the connector ground pin of the PCB. Like a structural member, the ground wire is ultimately connected to the power supply ground. In addition, for cable management, the cables are managed through methods such as bundling with a strap, a cable management slot, and the like. At present, there are many internal cables in the server, and the wires of the cables such as DC lines and MCIOs are connected to the ground through the PCB connector. The ground of the PCB is connected to the power supply ground pin. The entire grounding circuit does not strengthen the grounding of the cables, and the cable management is messy, which increases the possibility of exceeding the electromagnetic interference standard.

[0050] Through the server device provided in the present application, when the mainboard is designed, a connector area for grounding is respectively arranged on both sides of the mainboard, all the grounding connectors (first connection end and second connection end) are placed on both sides of the mainboard, which facilitates the connection of the metal structural member (fixing part) and the cable (connection cable) to the grounding pin (ground point). In association with the BMC monitoring function of the server, whether the grounding pin is in place and whether it is well connected is checked through the BMC. Inside the side wall of the case, a metal concentrator (concentrator) is designed, and the high-speed signal lines such as MICO and the low-speed lines such as DC pass through one side of the concentrator. In the center of the concentrator, a low-impedance copper core or iron core (cable connection part) is arranged, and the copper core is connected to the metal fixing frame on the outside wall of the case through a screw. The cable passes through one side of the concentrator, and the ground wire tap of all the cables is extracted in the middle of the concentrator and connected to the copper core in the center of the concentrator, and then connected to the grounding connector (first connection end) of the mainboard. Thus, the purpose of strengthening the grounding and connecting to the same grounding point is achieved.

[0051] On the other side of the inside wall of the case, a metal fixing frame (supporting part) is arranged, and all the movable metal structural members of the server are connected to the third grounding end on the metal fixing frame through copper wiring. The fourth connection end connected to the third connection end is arranged on the supporting part, and the fourth connection end is connected to the first connection end. At the same time, the metal fixing frame is connected to the ground pin connector of the mainboard (one end connected to the metal fixing frame and one end connected to the grounding connector on the mainboard), so that all the structural members are connected to the same grounding point through the grounding wire, thereby reducing the impedance difference and reducing the common mode interference.

[0052] Through the above design, the cable, the detachable structure member are all connected to the same grounding point, the purpose of minimum resistance difference is achieved. The electromagnetic radiation emission performance and anti-static interference performance of the server are improved, and when the electromagnetic emission test fails, it can be quickly checked whether the test fail is caused by the grounding problem. Since the grounding connectors on the mainboard are concentrated in the same area, it is convenient to check and rectify.

[0053] The application effectively solves the reliability of the server structure member (fixed component) and the case grounding, and reduces the resistance difference between each detachable metal structure member and the power supply ground, thereby avoiding common mode interference after the equipment is grounded. At the same time, the reliability of the cable grounding is solved, and the mutual crosstalk problem caused by cable arrangement is solved. The design improves the early warning method of the server grounding, and when the grounding is abnormal, it can be quickly checked and disposed in time to avoid EMC risk.

[0054] The above describes in detail a server device provided by the application. The principle and implementation mode of the application are described by applying specific examples in this paper. The above description of the embodiments is only used to help understand the method of the application and its core idea. It should be pointed out that for ordinary skilled persons in the technical field, some improvements and modifications can be made to the application without departing from the principle of the application, and these improvements and modifications also fall within the protection scope of the claims of the application.
