Example

[0018] Reference Figure 1-4 This is an embodiment of the present invention, which provides a high-speed backplane connector for an AI server, comprising: The support assembly 100 includes a base plate 101, a support plate 102 fixedly connected to the center of the base plate 101, a main positioning seat 103 fixedly connected to one side of the support plate 102, and a secondary positioning seat 104 fixedly connected to the other side of the support plate 102. The main positioning seat 103 and the secondary positioning seat 104 are symmetrically arranged on the outside of the support plate 102. The support plate 102 has a mounting groove in the middle that cooperates with the main positioning seat 103 and the secondary positioning seat 104. The connecting assembly 200 includes a main fixing seat 201 fixedly connected to one side of the end of the base plate 101, a main push rod 202 slidably inserted into the side wall of the end of the main fixing seat 201, a main connector male head 203 fixedly connected to the end of the main push rod 202, a secondary fixing seat 204 fixedly connected to the other side of the end of the base plate 101, a secondary push rod 205 slidably inserted into the side wall of the secondary fixing seat 204, a secondary connector male head 206 fixedly connected to the end of the secondary push rod 205, and a connector female head 207 fixedly connected to the inner side of the middle mounting groove of the support plate 102. The connector female head 207 is symmetrically installed on the side wall of the middle mounting groove of the support plate 102, and the connector female head 207 is used in conjunction with the main connector male head 203 and the secondary connector male head 206.

[0019] Specifically, a main support 208 is fixedly connected to the side wall of the main fixed base 201. A sleeve fitted onto the end of the main push rod 202 is installed at the end of the main support 208. A main handle 209 is hinged to the side wall of the main support 208. A main connecting rod 210 is hinged to the side wall of the main handle 209. The end of the main connecting rod 210 is hinged to the end of the main push rod 202. A main moving block 211 is slidably connected to the side wall of the base plate 101. The end of the main moving block 211 is engaged with the side wall of the main push rod 202. The side wall of the main moving block 211 has a slot for use with the male head 203 of the main connector.

[0020] Furthermore, a secondary bracket 212 is bolted to the side wall of the secondary fixed base 204. A sleeve fitted onto the side wall of the end of the secondary push rod 205 is installed at the end of the secondary bracket 212. A secondary handle 213 is hinged to the side wall of the secondary bracket 212. A secondary connecting rod 214 is hinged to the side wall of the secondary handle 213. The end of the secondary connecting rod 214 is hinged to the end of the secondary push rod 205. A secondary moving block 215 is slidably connected to the side wall of the base plate 101. The end of the secondary moving block 215 is engaged with the side wall of the secondary push rod 205. The side wall of the end of the secondary moving block 215 is provided with a clearance groove for use with the male head of the secondary connector 206.

[0021] It should be noted that the main moving block 211 and the auxiliary moving block 215 are symmetrically arranged on the outside of the support plate 102. A slide rail 216 is fixedly connected in the middle of the base plate 101. A slider 217 is slidably installed on the side wall of the slide rail 216. The sliders 217 are symmetrically arranged at the ends of the slide rail 216. The two sets of sliders 217 are respectively connected to the bottom of the main moving block 211 and the auxiliary moving block 215 by bolts.

[0022] Preferably, the main positioning seat 103 and the auxiliary positioning seat 104 are fixedly connected to a positioning rod 105 for use, and the end of the positioning rod 105 extends to the side wall of the main moving block 211 and the auxiliary moving block 215.

[0023] The base plate 101 provides the mounting reference for the entire device and can be fixed to the AI ​​server backplane frame with bolts. The support plate 102 is vertically fixed to the center of the base plate 101, and has a mounting groove in the middle to match the contour of the connector female head 207 for sealing installation of the connector female head. Two sets are symmetrically arranged to fit the main and auxiliary connector male heads respectively. The main positioning seat 103 and the auxiliary positioning seat 104 are symmetrically fixed on both sides of the support plate. The two and the support plate form a positioning structure to ensure that the coaxiality of the connector female head is consistent after installation and to provide guidance for the male head docking. The positioning rod 105 is used to limit the lateral displacement of the moving block and to provide sliding guidance for the moving block, ensuring that the main and auxiliary connector male heads move smoothly along the axial direction and avoiding misalignment during docking that could damage the signal pins. The main fixing seat 201 and the auxiliary fixing seat 204 are symmetrically fixed at both ends of the base plate 101, providing installation support for the main power and auxiliary power mechanisms, respectively. The main fixing seat 201 and the auxiliary fixing seat 204 are symmetrically fixed at both ends of the base plate 101, providing installation support for the main power and auxiliary power mechanisms, respectively. The main fixing seat has a main support 208 fixed to its side wall, with a sleeve installed at its end (fitted onto the end of the main push rod 202) to provide axial guidance for the push rod and prevent bending or displacement. The main handle 209 is hinged to the side wall of the main support 208 and is hinged to the end of the main push rod 202 via the main connecting rod 210. Using the lever principle, when the main handle is pressed, the connecting rod converts the rotational force into the axial thrust of the push rod, achieving smooth advancement of the main connector male head 203. Similarly, the auxiliary handle 213 drives the auxiliary push rod 205 and the auxiliary connector male head 206 to move via the auxiliary connecting rod 214, allowing for independent control or synchronous bidirectional docking. The main connector male head 203 is fixed. At the end of the main push rod 202 (compatible with the pins of the female connector 207, supporting high-speed differential signal transmission), the main moving block 211 is slidably connected to the side wall of the base plate 101, with its end engaged with the side wall of the main push rod 202. A slot adapted to the male connector of the main connector is provided in the middle. The moving block moves synchronously with the push rod, and the slot provides lateral fixation for the male connector of the main connector, enhancing the stability of the male connector. The male connector 206 of the auxiliary connector is fixed to the end of the auxiliary push rod 205. The auxiliary moving block 215 cooperates with the auxiliary push rod, and the end clearance groove provides installation space for the auxiliary male connector and also assists in fixation. A slide rail 216 (extending axially) is fixed in the middle of the base plate 101. The sliders 217 are symmetrically installed at the ends of the slide rail and are bolted to the bottom of the main and auxiliary moving blocks respectively. The slide rail and the slider cooperate to convert the sliding friction of the moving block into rolling friction, improving the smoothness of movement, while ensuring that the main and auxiliary male connectors move axially, meeting the accuracy requirements of physical connection for high-speed signal transmission.

[0024] During use, the base plate 101 is fixed with bolts to form a stable installation reference; the symmetrical layout of the support plate 102 and the main and auxiliary positioning seats allows the connector female head 207 to be accurately fixed in the mounting groove, providing a physical basis for high-speed signal transmission (reducing signal crosstalk); the positioning rod 105 cooperates with the guide groove on the side wall of the moving block to restrict the main and auxiliary moving blocks to slide only along the axial direction, avoiding lateral offset that would cause misalignment of the male and female heads, while also helping to maintain the straightness of the male head movement, ensuring that the pins are accurately inserted into the female head interface and reducing insertion and removal losses; When docking is required, press the main handle 209. The main connecting rod 210 drives the main push rod 202 to move axially along the main support sleeve. The main moving block 211 slides synchronously along the slide rail 216 with the push rod (with the positioning rod 105 providing auxiliary guidance). The main connector male head 203 smoothly approaches the connector female head 207. Similarly, the auxiliary handle 213 can be operated to drive the auxiliary male head forward, supporting unidirectional or bidirectional simultaneous docking. During the male head advancement, the slide rail and slider ensure linear movement, and the positioning rod limits lateral offset, so that the male head pins are accurately aligned with the female head interface until fully inserted (the high-speed signal channel is confirmed by the feel of the handle when docking is in place). At this time, the high-speed signal channel is activated, meeting the standard transmission requirements. When disassembly is required, reverse the main / auxiliary handles. The connecting rod drives the push rod and moving block to move in opposite directions, and the male head is smoothly pulled out of the female head, avoiding hard pulling that could cause pin bending or damage, thus improving the connector's service life.

[0025] In summary, the symmetrical structure of the supporting components reduces connector connection errors, and the differential signal design of the male pins effectively reduces signal crosstalk. The guiding structure of the connecting components restricts the male pin to move only axially, avoiding lateral deviation. The lever-driven smooth advancement ensures that the male pins are accurately inserted into the female connector interface, reducing pin damage and failure rates. Simultaneously, the lateral fixation of the male pin by the main / secondary moving blocks resists vibrations during server operation, improving connection stability. Utilizing a lever-driven principle, docking is completed by pressing the handle, eliminating the need for direct force on the functional module, reducing operational effort and preventing module deformation. It supports independent or synchronous operation of the main / secondary male pins, and the bidirectional docking design allows simultaneous connection of two sets of functional modules. No additional connectors are needed for expansion, and during maintenance, the handle can be smoothly separated by reverse lever operation, shortening downtime for maintenance. The bidirectional docking structure supports parallel connection of two modules with a single connector, saving backplane interface and internal space, adapting to the high-density module deployment requirements of AI servers. It can be quickly fixed to the backplane frame of different AI server models using bolts, adapting to various server specifications and offering strong versatility.
