[0002] This application claims priority to Chinese Patent Application No. 202411045675.8, filed on July 31, 2024, entitled “A Signal Connector and Server”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of signal transmission technology, and more specifically, to a signal connector and server. Background Technology

[0004] A multi-node server is a type of server that houses one, two, or more node enclosures within a single server chassis. These node enclosures are installed in a pluggable manner within the chassis. Each node enclosure contains a motherboard, which interconnects with an adapter board within the server chassis via power connectors and high-speed connectors located on the motherboard, enabling the transmission of electrical and high-speed signals.

[0005] One approach to achieve high-speed signal transmission involves placing a high-speed connector on the motherboard and a high-density connector on the corresponding location on the server chassis's adapter board. The high-density connector contains vertically arranged, layered cables. Signal transmission from the motherboard to the device is achieved by connecting the high-speed connector to the high-density connector, and then connecting the high-density connector's cables to the device. However, this method results in a relatively tall high-density connector, occupying significant chassis height and potentially affecting the chassis's fan components, increasing system air resistance, and consequently, power consumption. Summary of the Invention

[0006] In view of this, the purpose of this application is to provide a signal connector that reduces the overall height of the cable by soldering a single layer of cable onto a wire bonding PCB board, thereby reducing the height space occupied inside the chassis, avoiding interference with the operation of the fan components inside the chassis, avoiding unnecessary energy consumption, facilitating cable bending and winding, and having good applicability.

[0022] On the other hand, the mounting component includes a first cover and a second cover connected thereto, and a protective shell is disposed within a first limiting part inside the first cover, with a gap between the first limiting part and the protective shell.

[0023] The cable passes through the second limiting part inside the second cover. The second limiting part is smaller than the first limiting part and can prevent the protective shell from moving backward along the insertion direction.

[0024] On the other hand, the front end of the second cover is provided with a buckle that engages with the first cover;

[0025] The rear end of the second cover is provided with a second mounting part, which is used to connect with the guide pin on the adapter plate to limit the offset of the mounting part along the insertion direction of the insertion part and the high-speed connector.

Detailed Implementation

[0057] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0058] The core of this application is to provide a signal connector that reduces the overall height of the cable by soldering a single-layer cable onto a wire bonding PCB (Printed Circuit Board), thereby reducing the height space occupied within the chassis, avoiding interference with the operation of the fan components inside the chassis, preventing unnecessary energy consumption, facilitating cable bending and winding, and exhibiting good applicability. Another core aspect of this application is to provide a server incorporating the aforementioned signal connector.

[0059] The signal connector provided in this application is located on the adapter board 2 and is used to connect the motherboard 1 and the device to realize signal transmission. Please refer to Figures 13 and 15.

[0060] Please refer to Figures 1, 7, and 8. The signal connector specifically includes a mounting component 63, a wire bonding PCB board 61, and a cable 613. The mounting component 63 has a limiting part, and the wire bonding PCB board 61 is inserted into the limiting part. The cable 613 is soldered onto the wire bonding PCB board 61. By fixing the mounting component 63 to the adapter board 2, the signal connector and the adapter board 2 can be connected, which is simple and convenient.

[0061] The wire bonding PCB board 61 is inserted into the limiting part. In one specific embodiment, the wire bonding PCB board 61 and the limiting part are tightly fitted to ensure the stable and reliable connection between the two.

[0062] Taking another specific implementation as an example, the wire bonding PCB board 61 and the limiting part are reliably connected, and there is a certain adjustment margin between them. The positional accuracy requirements of the two are not high, which facilitates flexible connection between the two.

[0063] It should be noted that the two specific implementation methods described above are essentially aimed at achieving a stable connection between the wire bonding PCB board 61 and the mounting component 63, ensuring the stability and reliability of the overall structure when it is plugged into the motherboard 1 to form a signal transmission.

[0064] The wire bonding PCB board 61 is provided with a cable section 612 and a plug section 611. The cable section 612 and the plug section 611 are an integral structure. The wire bonding PCB board 61 is insulated, but the cable section 612 and the plug section 611 use the circuit of the wire bonding PCB board 61 itself to realize signal transmission.

[0065] The cable 613 is connected to the cable section 612 via a soldering plane on the cable section 612. The cable 613 connects the device and the cable section 612. The plug section 611 connects to the high-speed connector 5 on the motherboard 1. Therefore, signal transmission between the high-speed connector 5 and the device can be achieved through the cable 613, that is, the outward transmission of signals from the motherboard 1. This direct cable routing solution reduces signal attenuation caused by signal conversion during connector transmission and improves the quality of signal connection.

[0066] The specific form of the plug-in part 611 is not limited, as long as it cooperates with the high-speed connector 5 to achieve signal transmission through plugging. For example, if the high-speed connector 5 has multiple spring contacts, the plug-in part 611 can be divided into multiple plug-in ends that correspond one-to-one with the spring contacts. As shown in Figure 8, the plug-in part 611 is divided into four plug-in ends with gaps between them. The entire plug-in part 611 is hand-shaped, and each plug-in end can be regarded as a finger.

[0067] The cable section 612 has a welding plane, on which a cable 613 is provided. The cable 613 includes a single-layer transmission line welded to the welding plane. The specific size of the welding plane can be flexibly set according to the actual situation and is not limited. In addition, the welding plane is not limited to one. If two welding planes are set, the two welding planes are located in the same plane, and each welding plane corresponds to a different cable 613, which is set according to actual needs.

[0068] Cable 613 may include transmission lines, with several transmission lines soldered in a single layer onto a soldering plane for connecting equipment. When cable 613 includes multiple transmission lines, these lines may be densely arranged on the soldering plane or spaced apart.

[0069] It should be noted that after the cable 613 is welded to the welding plane, adhesive is applied to the corresponding position of the cable 613 on the cable part 612 to carry out insulation and anti-corrosion protection measures, ensuring the reliable and stable operation of the cable 613.

[0070] In one embodiment, to ensure the reliability of the cable 613 being welded to the welding plane, a clamping part can be provided on the cable part 612 to clamp the cable 613 and prevent the cable 613 from falling off and failing during use.

[0071] A single-layer cable 613 is soldered onto a soldering plane. The cable 613 and the soldering PCB board 61 can be processed into a single unit. This single unit can be modularly produced. When used for signal transmission between the motherboard 1 and the device, this single unit is connected to the mounting part 63, and then the adapter board 2 is connected through the mounting part 63. The cable 613 is connected to the device, and the plug-in part 611 is plugged into the high-speed connector 5 on the motherboard 1.

[0072] By using a single-layer cable 613, the overall height of the cable 613 is reduced, thus minimizing the height space it occupies when installed in the server chassis. Consequently, the overall height of the bonding PCB board 61 is also effectively reduced. The mounting component 63 is designed to accommodate the insertion of the bonding PCB board 61, thus its height is also effectively reduced. In summary, the overall height of the signal connector is reduced, avoiding its impact on internal components of the chassis, such as the fan assembly. This prevents the signal connector's height from obstructing or affecting the airflow of the fan assembly, thereby preventing unnecessary energy consumption.

[0073] The single-layer cable 613 facilitates pre-bending and winding of the cable 613. The cable 613 can be bent or wound appropriately according to the actual situation, thereby improving the applicability of the signal connector.

[0074] The signal connector provided in this application is used to connect a motherboard 1 and a device to achieve signal transmission. Specifically, it includes a mounting component 63, a wire bonding PCB board 61, and a cable 613. The mounting component has a limiting part and is used to connect to an adapter board to fix the wire bonding PCB board 61 and the cable 613 on the adapter board 2. The wire bonding PCB board 61 is inserted into the limiting part. The wire bonding PCB board 61 has a cable part 612 and a plug-in part 611. The cable part 612 and the plug-in part 611 achieve signal communication through the internal circuit of the wire bonding PCB board 61. The plug-in part 611 is plugged into the motherboard 1. The high-speed connector 5 on board 1 has a cable 613 soldered on the soldering plane of the cable section 612. The high-speed connector 5 on the motherboard 1 and the external device are transmitted through the cable 613. The cable 613 includes transmission lines, and several transmission lines are soldered in a single layer on the soldering plane to reduce the overall height of the cable 613 and reduce the height space occupied by the cable 613 in the chassis, so as to avoid affecting the operation of the fan assembly in the chassis and avoid unnecessary energy consumption. In addition, the single-layer cable arrangement makes the cable easy to bend and wind, expanding the applicable scenarios of the signal connector.

[0075] By soldering a single layer of cable onto the wire bonding PCB board, the overall height of the cable is reduced, thus reducing the height space occupied inside the chassis. This avoids affecting the operation of the fan components inside the chassis, prevents unnecessary energy consumption, and facilitates cable bending and winding, making it highly adaptable.

[0076] Based on the above embodiment, the welding plane is provided on the upper surface of the cable portion 612;

[0077] Alternatively, the welding plane may be located on the lower surface of the cable section 612;

[0078] Alternatively, the welding planes may be located on the upper and lower surfaces of the cable section 612.

[0079] Please refer to Figures 7 and 8. In one embodiment, the welding plane is provided on the upper surface of the cable section 612, and the signal transmission between the cable 613 and the wire bonding PCB board 61 is achieved by welding a single layer cable 613 on the upper surface.

[0080] In another embodiment, the welding plane is located on the lower surface of the cable section 612, and the signal transmission between the cable 613 and the wire bonding PCB board 61 is achieved by welding a single layer cable 613 on the lower surface.

[0081] Both of the above specific implementation methods use a single-layer cable 613 to achieve signal transmission. That is, a single-layer cable 613 can meet the signal transmission requirements. The specific cable 613 can be flexibly selected to be soldered on the upper or lower surface of the cable part 612 according to the actual situation, and the design should be based on the actual installation situation, operation requirements, etc.

[0082] When a single-layer cable 613 cannot meet the signal transmission requirements, two layers of cable 613 are set by providing welding planes on both the upper and lower surfaces of the cable section 612. In this case, the overall height of the cable 613 is still limited by the overall height of the cable section 612. Each layer of cable 613 is still laid flat and welded. Therefore, the overall height of the cable section 612 can still be kept small, ensuring that the overall structure still occupies a relatively small height space.

[0083] Based on any of the above embodiments, a protective housing 62 is also included, which is connected to and covers the cable portion 612.

[0084] The protective housing 62 has a gap between at least one side and the limiting portion, allowing the protective housing 62 and the wire bonding PCB board 61 to be positioned within the limiting portion.

[0085] Please refer to Figures 6, 7, and 8. The signal connector also includes a protective shell 62, which is connected to and covers the cable section 612 to provide a certain degree of protection for the cable 613 connected inside the cable section 612. Specifically, the protective shell 62 is set to be insulated, and the inner wall of the protective shell 62 is attached to the cable 613.

[0086] It should be noted that both the connector 611 and the cable 613 extend beyond the protective shell 62, without affecting the connector operation or the operation of the cable connection equipment. The protective shell 62 only provides protection for the welded portion of the cable 613 on the welding plane. To provide physical protection for the welding plane and prevent the cable 613 from loosening during assembly or pulling, the protective shell 62 is formed on the outside of the bonding PCB board 61 by injection molding. The protective shell 62, the bonding PCB board 61, and the cable 613 are tightly bonded together.

[0087] There is a gap between at least one side of the protective shell 62 and the limiting part, such as a gap between the upper side of the protective shell 62 and the limiting part of the mounting part 63. When the wire bonding PCB 61 is connected to the high-speed connector 5 on the motherboard 1, there is a certain adjustment space in the vertical direction, so as to adjust the position of the wire bonding PCB 61 in the vertical direction within the limiting part, which facilitates its floating installation with the high-speed connector 5, reduces the requirements for installation position accuracy, improves installation flexibility, avoids collision problems caused by misalignment, and ensures the service life of the wire bonding PCB 61 and the high-speed connector 5.

[0088] If there are gaps between the left and right sides of the protective shell 62 and the limiting part of the mounting part 63, when the wire bonding PCB board 61 is connected to the high-speed connector 5 on the motherboard 1, there can be a certain adjustment space in the left and right directions, so as to adjust the position of the wire bonding PCB board 61 in the left and right directions within the limiting part, which facilitates its floating installation with the high-speed connector 5, reduces the requirements for installation position accuracy, improves installation flexibility, avoids collision problems caused by misalignment, and ensures the service life of the wire bonding PCB board 61 and the high-speed connector 5.

[0089] If the protective shell 62 has gaps between its four sides (top, bottom, left, and right) and the limiting part, when the wire bonding PCB 61 is connected to the high-speed connector 5 on the motherboard 1, there is a certain adjustment space in the top, bottom, left, and right directions. This allows the position of the wire bonding PCB 61 to be adjusted within the limiting part, facilitating its floating installation with the high-speed connector 5, reducing the requirements for installation position accuracy, improving installation flexibility, avoiding collision problems caused by misalignment, and ensuring the service life of the wire bonding PCB 61 and the high-speed connector 5.

[0090] Based on any of the above embodiments, at least one inner wall of the limiting part includes a flat part and a convex part that protrudes from the flat part. The convex part is disposed close to the protective shell 62 relative to the flat part, and the flat part is disposed corresponding to the corner of the protective shell 62.

[0091] Please refer to Figure 6. The specific shape of the limiting part can be set as a rectangle, square, trapezoid, circle, irregular shape, etc. The limiting part can be matched with the protective shell 62.

[0092] The inner wall of the limiting part includes a flat part and a convex part that protrudes from the bottom surface. There is a gap between a side of the protective shell 62 and the limiting part, so that the protective shell 62 and the bonding PCB board 61 can be adjusted in position within the limiting part, which facilitates their floating installation with the high-speed connector 5.

[0093] In one specific embodiment, the protective shell 62 is rectangular, and the limiting part is also rectangular. At least one inner wall of the limiting part includes a flat part and a convex part that protrudes from the bottom surface. By setting the convex part and the flat part, the inner wall of the protective shell 62 has a stepped shape to form a floating space for installation.

[0094] As shown in Figure 6, the convex part is positioned close to the protective shell 62 relative to the plane, and the flat part is positioned corresponding to the corner part of the protective shell 62. Taking the inner wall of the limiting part as including both the flat part and the convex part as an example, the flat part of the inner wall of two adjacent limiting parts forms a corner area. There is a gap between the corner area and the protective shell 62, so that the overall component formed by the protective shell 62, the wire bonding PCB board 61, and the cable 613 can be appropriately positioned and adjusted within the limiting part, ensuring that the plug part 611 on the wire bonding PCB board 61 can be reliably connected to the high-speed connector 5 of the motherboard 1.

[0095] It should be noted that the flat part is located close to the protective shell 62, and there is a certain gap between the flat part and the side of the protective shell 62. This gap allows the overall component formed by the protective shell 62, the wire bonding PCB board 61, and the cable 613 to have a certain adjustment space while preventing the overall component from falling out of the limiting part.

[0096] To prevent the aforementioned integrated component from falling out within the limiting part and affecting the signal connection with the motherboard 1, a blocking part can be provided on the mounting part 63. This blocking part prevents the integrated component formed by the protective shell 62, the bonding PCB board 61, and the cable 613 from moving along the insertion direction when plugged into the motherboard 1. This ensures that the integrated component moves up, down, left, and right within the limiting part, preventing forward and backward movement and guaranteeing stable and reliable plugging. The blocking part is positioned to avoid the cable part 612 and the plug-in part 611, so it does not affect the connection of the device or the plugging operation of the motherboard 1.

[0097] For example, the blocking part can be set as a baffle, which is rotatably connected to the mounting part 63. During use, it rotates to block the front and rear walls of the protective shell 62, preventing the protective shell 62 from moving in the front and rear direction, ensuring the reliable stability of the insertion and avoiding collisions. Here, the front and rear walls are in the same direction as the insertion direction.

[0098] When not in use, the baffle can be rotated to be folded up onto the mounting piece 63 without interfering with the orientation adjustment of the protective shell 62, allowing it to be adjusted in multiple directions.

[0099] In addition, the baffle is configured to be rotatably connected to the mounting component 63, so that the baffle can be rotated to the retracted state for the installation of the overall component formed by the protective shell 62, the bonding PCB board 61, and the cable 613. After installation, the baffle can be rotated to block the front and rear walls of the protective shell 62 or kept in the retracted state, depending on the actual situation.

[0100] Based on any of the above embodiments, at least one of the protective housing 62 and the mounting member 63 is provided with a foolproof part for guiding the insertion part 611 into the high-speed connector 5.

[0101] In this embodiment, the mis-proof part ensures the guidance of the insertion part 611 and the high-speed connector 5, avoiding damage to components or collision problems caused by incorrect insertion direction, which would affect signal transmission and work efficiency.

[0102] The error-proof feature can be a mark or symbol, such as text, raised areas, grooves, or patterns, to indicate the direction and prevent the connector 611 on the wire bonding PCB 61 from being installed in reverse, ensuring reliable and accurate connection between the connector 611 and the high-speed connector 5 of the motherboard 1. At least one of the protective housing 62 and the mounting component 63 has an error-proof feature. This is because the wire bonding PCB 61 itself has a forward and reverse orientation. The protective housing 62 is formed on the outside of the wire bonding PCB 61 through injection molding, therefore the forward and reverse orientations of the protective housing 62 and the wire bonding PCB 61 are consistent. The orientation of the connector 611 can be determined by using the error-proof feature to determine the orientation of the protective housing 62.

[0103] To facilitate operator work, the foolproof part can also be coated with a fluorescent layer to ensure accurate installation of the protective housing 62 and mounting component 63 in low-light conditions. Furthermore, the fluorescent layer allows users to quickly see markings or signs and determine direction. The specific area of ​​the fluorescent layer coated on the foolproof part can be set according to actual conditions, facilitating visual operation.

[0104] In one specific embodiment, the mis-proof part is provided on the protective shell 62, and the direction of the mounting part 63 is determined (e.g., it has been fixed on the adapter plate 2). The installation direction of the plug part 611 can be determined by determining the direction of the mis-proof part.

[0105] In another specific embodiment, the mis-proof part is provided on the mounting member 63. After the protective shell 62 is correctly installed on the mounting member 63, the mounting member 63 is fixed to the adapter plate 2. By determining the installation direction of the mis-proof part and the mounting direction of the mounting member 63, that is, the installation direction of the protective shell 62, the installation direction of the plug-in part 611 is determined.

[0106] In another specific embodiment, the error prevention part is provided on the mounting part 63 and the protective shell 62. The error prevention part on the mounting part 63 and the protective shell 62 cooperate to guide the installation direction and ensure the installation direction of the plug part 611.

[0107] Based on any of the above embodiments, the inner wall of the limiting part is provided with a foolproof groove 6311, the protective shell 62 is provided with a foolproof protrusion 621, and the foolproof protrusion 621 is disposed in the foolproof groove 6311.

[0108] There is a gap between the outer periphery of the anti-mistake protrusion 621 and the groove wall of the anti-mistake groove 6311.

[0109] Please refer to Figures 4 and 5. The specific foolproof design involves the cooperation of the foolproof groove 6311 and the foolproof protrusion 621. The inner wall of the limiting part is provided with a foolproof groove 6311. When the protective shell 62, the bonding PCB board 61, and the cable 613 are installed into the limiting part of the mounting part 63, the foolproof protrusion 621 is inserted along the direction of the foolproof groove 6311 to ensure the correct installation direction and the accuracy of the direction in which the plug-in part 611 is plugged into the motherboard 1.

[0110] The anti-foolproof groove 6311 and anti-foolproof protrusion 621 also provide guidance for the connection between the protective shell 62 and the mounting part 63, ensuring the accuracy of the connection between the two.

[0111] There is a gap between the outer periphery of the anti-mistake protrusion 621 and the groove wall of the anti-mistake groove 6311, which further provides adjustable space for the protective shell 62, making the position of the plug part 611 more adjustable and more flexible.

[0112] Specifically, there can be one, two, or more gaps between the outer periphery of the anti-mistake protrusion 621 and the groove wall of the anti-mistake groove 6311, depending on the actual installation situation. Here, one gap refers to one groove wall of the anti-mistake groove 6311.

[0113] Based on any of the above embodiments, the mounting component 63 is provided with a first mounting part 6312 for connecting with the adapter board 2, and the mounting component 63, the protective shell 62, and the wire bonding PCB board 61 are connected in sequence from the outside to the inside.

[0114] Please refer to Figures 1, 4, and 9. The mounting part 63 is provided with a first mounting part 6312 for connecting with the adapter plate 2. The first mounting part 6312 can be in the form of a hole, a slot, etc.

[0115] After the cable 613 is soldered to the wire bonding PCB board 61, it is connected to the protective shell 62 and then installed in the limiting part of the mounting part 63 to complete the installation of the signal connector. The installed whole component can be regarded as a relatively complex signal transmission cable. The convenient and quick installation of this signal transmission cable can be achieved by connecting the first mounting part 6312 and the adapter board 2, thereby improving the applicability of the connector.

[0116] The specific location and number of the first mounting part 6312 on the mounting component 63 are not limited, and can be defined according to actual design requirements.

[0117] Based on any of the above embodiments, the mounting member 63 includes a first cover 631 and a second cover 632 connected thereto, and the protective shell 62 is disposed in the first limiting part 6313 inside the first cover 631, and there is a gap between the first limiting part 6313 and the protective shell 62.

[0118] The cable 613 passes through the second limiting part 6321 inside the second cover 632. The second limiting part 6321 is smaller than the first limiting part 6313 and can prevent the protective shell 62 from moving backward along the insertion direction.

[0119] Please refer to Figures 1, 2, and 3. The mounting component 63 includes a first cover 631 and a second cover 632 connected thereto. In a specific embodiment, the two are detachably connected, such as by fasteners, by ring clamps, or by snap-fit ​​connectors, etc., to facilitate installation and disassembly.

[0120] The first cover 631 is provided with a first limiting part 6313, and the second cover 632 is provided with a second limiting part 6321. The protective shell 62 is provided inside the first limiting part 6313. The first limiting part 6313 can be set slightly larger than the protective shell 62, so as not to affect the extension of the cable part 612 and the plug part 611, to ensure reliable limiting of the protective shell 62 and prevent the protective shell 62 from falling out of the first limiting part 6313.

[0121] There is a gap between the first limiting part 6313 and the protective shell 62 to facilitate the floating installation of the wire bonding PCB board 61 and the motherboard 1.

[0122] The cable 613 passes through the second limiting part 6321 inside the second cover 632 and connects to the equipment. Specifically, the second limiting part 6321 is smaller than the first limiting part 6313, which can allow the cable 613 to extend and prevent the protective shell 62 from moving backward along the insertion direction, thus avoiding the situation where the solder PCB board 61 falls off and ensuring the reliability and stability of its operation.

[0123] The second limiting part 6321 is smaller than the first limiting part 6313. Specifically, taking the example that both limiting parts are rectangular, the centers of the second limiting part 6321 and the first limiting part 6313 are aligned, the length of the second limiting part 6321 is less than the length of the first limiting part 6313, and the width of the second limiting part 6321 is less than the width of the first limiting part 6313.

[0124] Based on any of the above embodiments, the front end of the second cover 632 is provided with a buckle 6322 that engages with the first cover 631;

[0125] The rear end of the second cover 632 is provided with a second mounting part 6323, which is used to connect with the guide pin 21 on the adapter plate 2 to limit the offset of the mounting part 63 along the insertion direction of the insertion part 611 and the high-speed connector 5.

[0126] Please refer to Figures 2, 3, and 4. The front end of the second cover 632 is provided with a buckle 6322 that engages with the first cover 631. Correspondingly, the first cover 631 is provided with a snap-fit ​​part 6314. Through the snap-fit ​​part 6314 and the buckle 6322, the first cover 631 and the second cover 632 are reliably connected, ensuring the reliable stability of the wire bonding PCB board 61 installed in the limiting part.

[0127] In this embodiment, the snap-fit ​​part 6314 and the buckle 6322 can be either rigid or elastic. The rigid snap-fit ​​is achieved by a hook being fitted onto the snap-fit ​​block, while the elastic snap-fit ​​is achieved by a snap-fit ​​by a snap-fit ​​hook being compressed to extend into the snap-fit ​​groove. Both snap-fit ​​methods can achieve reliable installation between the two covers, and there is no specific limitation.

[0128] In this embodiment, the position and number of the snap-fit ​​part 6314 and the buckle 6322 installed on the cover are not limited, and can be set according to the principle of facilitating installation and reducing the overall installation height of the connector.

[0129] In one specific embodiment, after the snap-fit ​​part 6314 and the latch 6322 are snapped together, the plane of the latch 6322 is lower than or equal to the top surface of the first cover 631, so as to reduce the height of the snap-fit ​​part, reduce the overall height of the connector, and avoid obstructing the internal components of the chassis.

[0130] The rear end of the second cover 632 is provided with a second mounting part 6323. The second mounting part 6323 is used to connect with the guide pin 21 on the adapter plate 2 to limit the offset of the mounting part 63 along the insertion direction of the insertion part 611 and the high-speed connector 5, so that the limiting part can ensure good stability and ensure the stability and reliability of the wire bonding PCB board 61 in the limiting part for installation and adjustment.

[0131] Specifically, the second mounting part 6323 can be a cylindrical structure, and a stepped hole can be provided inside the cylinder. The stepped hole is connected to the guide pin 21 to ensure the reliability of the connection between the two and to avoid the offset of the mounting part 63 in the insertion direction.

[0132] Based on any of the above embodiments, a plurality of buckles 6322 are symmetrically arranged on both sides of the second limiting part 6321, and the first cover 631 is provided with a guide surface for the buckles 6322 to engage.

[0133] Please refer to Figures 2 and 3. Multiple buckles 6322 are provided. Specifically, multiple buckles 6322 are symmetrically arranged on both sides of the second limiting part 6321. Both sides of the first cover 631 and the second cover 632 have snap-fit, ensuring the reliable and stable connection between the two.

[0134] The first cover 631 is provided with a guide surface, which facilitates the quick and accurate insertion of the buckle 6322 into the snap-fit ​​part 6314, so that the first cover 631 and the second cover 632 can be snapped into place quickly and accurately, thereby improving the efficiency and accuracy of installation.

[0135] Specifically, the guide surface can be a plane such as an inclined plane or an arc surface that can achieve a guiding function, which can realize the quick connection between the first cover 631 and the second cover 632.

[0136] In addition to the signal connectors described above, this application also provides a server including the signal connectors disclosed in the above embodiments, comprising:

[0137] Chassis 8;

[0138] The adapter board 2 is located inside the chassis 8, and the signal connector 6, as in any of the above embodiments, is located on the adapter board 2;

[0139] Motherboard 1 is located inside chassis 8 and is electrically connected to adapter board 2;

[0140] High-speed connector 5 is located on motherboard 1 and connected to signal connector 6;

[0141] The fan assembly 9 is located on the adapter plate 2, and the signal connector 6 is located in the height space formed by the adapter plate 2 and the fan assembly 9.

[0142] Please refer to Figures 12 and 14. The signal connector 6 and the high-speed connector 5 on the motherboard 1 are plugged in to form a signal transmission. The cable 613 on the signal connector 6 is connected to the device to realize the signal transmission between the motherboard 1 and the device.

[0143] Both the adapter board 2 and the motherboard 1 are located inside the chassis 8. The power connector on the adapter board 2 is connected to the power connector 4 on the motherboard 1 to provide power.

[0144] When the adapter board 2 and the motherboard 1 are connected, the installation positions of the two are initially aligned by the guide pins 3. Then, the power connector on the adapter board 2 and the corresponding power connector 4 on the motherboard 1 cooperate with each other by relying on their own guiding structure until the male and female ends of the connectors are fully inserted into place to complete the transmission of electrical signals.

[0145] The signal connector 6 on the adapter board 2 and the high-speed connector 5 on the main board 1 are connected to achieve high-speed signal transmission. The aforementioned arrangement of the signal connector 6 allows it to be floated with the high-speed connector 5, avoiding the risk of collision between them, ensuring reliable and effective connection, and guaranteeing reliable signal transmission.

[0146] Please refer to Figures 15 and 12. The fan assembly 9 is located on the adapter plate 2, and may include a fan frame and a fan module, etc., for cooling the chassis 8. The signal connector 6 is located in the height space formed by the adapter plate 2 and the fan assembly 9. That is, the height of the signal connector 6 will not block the fan assembly 9, and the overall area of ​​the signal connector 6 will not block the fan assembly 9. It will not affect the air intake of the fan assembly 9, will not interfere with the fan assembly 9, will not increase the air resistance of the system, and will ensure the normal operation of the fan assembly 9 and the reliability of the server operation.

[0147] Based on the above embodiments, the high-speed connector 5 is provided with a spring piece that connects to the insertion part 611, and the highest point of both the high-speed connector 5 and the signal connector 6 is lower than the lowest point of the fan assembly 9.

[0148] The number of spring contacts in the high-speed connector 5 and the finger structures on the insertion part 611 are configured one-to-one for signal transmission. The spring contacts and the finger structures (i.e., the four corresponding finger-like structures on the insertion part 611) contact each other to achieve signal transmission, and the reliable connection between the two ensures the reliability and quality of signal transmission.

[0149] The highest points of high-speed connector 5 and signal connector 6 are both lower than the lowest point of fan assembly 9, so that the operation of fan assembly 9 is not interfered with, avoiding increased system energy consumption and ensuring the reliability of server operation.

[0150] Based on any of the above embodiments, the fan assembly 9 is provided with a stop portion 91, which abuts against the mounting member 63 to restrict its movement along the insertion direction.

[0151] Alternatively, the stop portion 91 is connected to the mounting member 63 to restrict its movement along the insertion direction.

[0152] Please refer to Figures 1 and 14. The stop part 91 is located at the lower end of the fan assembly 9 and extends into the height space. The cooperation between the stop part 91 and the mounting part 63 restricts the movement of the mounting part 63 in the insertion direction, so as to avoid affecting the insertion of the wire bonding PCB board 61 and the high-speed connector 5, and restricts the floating of the wire bonding PCB board 61 in the limiting part to the up, down and left and right directions.

[0153] Please refer to Figures 11 and 14. The stop part 91 is specifically the bent part at the lower end of the fan assembly 9. This bent part is formed by a component inside the fan frame, extends out of the limiting hole on the fan frame and abuts or connects to the mounting part 63 to restrict the movement of the mounting part 63 in the insertion direction. The stop part 91 presses the mounting part 63 from the rear to prevent the mounting part 63 from being deformed by the impact of the high-speed connector 5 of the motherboard 1 and the plug-in part 611 during the rapid impact when the node plug box 7 is inserted into the chassis 8. This ensures the insertion depth of the plug-in part 611 and ensures reliable signal transmission.

[0154] The size of the limiting hole on the fan frame is designed according to actual operating conditions, so that the stop part 91 can extend and the bending part can be moved to a certain extent. The thickness of the bending part can be set to be large, and the corresponding material can be set to a high-strength material, so that the bending part is not easily deformed, which can ensure reliable limiting of the mounting part 63, avoid the mounting part 63 being deformed by impact, ensure the insertion depth of the plug-in part 611, and ensure reliable and effective signal transmission.

[0155] In one embodiment, the stop portion 91 abuts against the mounting member 63 to restrict its rearward movement in the insertion direction.

[0156] In another specific embodiment, the stop portion 91 is connected to the mounting member 63 to restrict its rearward movement in the insertion direction. This connection can be achieved by providing a slot at the rear end of the mounting member 63, into which the stop portion 91 engages to form a limit.

[0157] Based on any of the above embodiments, the server also includes a captive screw 64, and the mounting component 63 is connected to the stud 22 on the adapter plate 2 by the captive screw 64 to realize the connection between the signal connector 6 and the adapter plate 2.

[0158] Please refer to Figures 2, 3, 4, and 9. The captive screw 64 passes through the first mounting portion 6312 on the mounting piece 63 and connects to the adapter plate 2. Specifically, the captive screw 64 connects to the stud 22, achieving the connection between the signal connector 6 and the adapter plate 2 without the need for tools. The axes of both the captive screw 64 and the stud 22 are perpendicular to the insertion direction, forming a limit on the vertical direction of the mounting piece 63. This prevents the high-speed connector 5 of the motherboard 1 from deforming the mounting piece 63 during rapid impact when the node insertion box 7 is inserted into the chassis 8, ensuring the insertion depth of the insertion portion 611 and guaranteeing reliable signal transmission.

[0159] The combination of the non-removable screw 64 and the stop part 91 forms two stops in different directions, ensuring the insertion depth of the plug part 611, ensuring reliable signal transmission, and ensuring the service life of the signal connector.

[0160] There is no limit to the specific number of the 64 non-removable screws; a relatively stable connection can be achieved to ensure a reliable connection between the signal connector and the adapter board 2.

[0161] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
