Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of computing devices, and in particular, to a single board, a computing device, and a method for determining a connection status of a connector. Background Art

[0002] Internet service providers, enterprise platforms, research institutions, etc. all have a large number of computing needs. The operating platform that carries storage, computing, and network needs is called a data center. With the rise of big data, cloud computing, and artificial intelligence (AI), the computing needs of data centers and servers are getting higher and higher, and the exchange rate between server nodes and networks is also gradually increasing.

[0003] The computing equipment in the data center includes single boards. For example, switch boards, etc. Single boards can be inserted into computing equipment. The connector on the single board docks with the connector on the opposite device. After the two connectors are docked, there may be a gap (Demating). The size of the gap has a great influence on the impedance. Too large a gap will cause impedance mutation, thereby affecting signal integrity and affecting the working reliability of the single board. At this time, the operator needs to take timely measures to reduce the gap to within the allowable target spacing threshold.

[0004] In the related art, a distance sensor is usually used to detect the mating gap. The distance sensor can be located on a single board. When two distance sensors are docked, the distance sensor can be used to detect the distance between the opposite device, so that based on the distance, it can be determined whether the connection status between the connectors is normal. However, the distance sensor is large in size, and the location of the distance sensor layout is limited by its own size. The distance sensor can only be arranged in a certain area, and its detection range is limited. Therefore, it is easy to lead to low detection accuracy, and even prone to misdetection, affecting the reliability of the single board operation. Summary of the invention

[0005] The embodiments of the present application provide a single board, a computing device, and a method for determining the connection status of a connector, which can solve the problem that the detection accuracy of the mating gap is low, which easily leads to misdetection and thus easily affects the reliability of the single board operation.

[0006] In a first aspect, an embodiment of the present application provides a single board, including a circuit board and a first connector. The first connector is arranged on the circuit board, and the first connector is used to dock with a second connector of an opposite device. The first connector includes a plurality of first connection parts, and the first connection parts are used to transmit signals with the second connector; the outer wall of the first connection part is provided with a detection part constituting a detection layer, and the detection part is used to detect the connection state between the first connector and the second connector.

[0007] In the single board provided in the embodiment of the present application, a detection coating is provided on the first connector of the single board to form a detection part. By providing the detection coating on the outer wall of the first connection part and forming the detection part, the second connector can form a wear mark on the detection coating of the detection part during the docking process between the first connector and the second connector. Therefore, by detecting the size of the wear mark along the docking direction, it can be used to confirm the connection state between the first connector and the second connector, and the detection accuracy is high, thereby confirming whether the connection state between the first connector and the second connector can meet the requirements.

[0008] Moreover, compared with the method of arranging a distance sensor, the method of detecting the matching gap by detecting the plating layer is less expensive and does not require an additional fixing structure to be provided on the first connector or the second connector. The detection method is simple and convenient, and can effectively improve the detection efficiency.

[0009] Since the detection coating is a thin layer structure and has a small volume, the detection coating is not easily limited by its own volume or the space on the first connector, and the detection coating can be provided on any first connection part. Therefore, the operator can set the position of the detection part according to the shape of the mating surface of the first connector and the second connector, so as to achieve high-precision detection with a small number of detection parts. For example, according to the shape of the mating surface of the first connector and the second connector, the detection part can be located in the middle, at the edge, at the corner, etc.

[0010] In a possible implementation, there are multiple first connection parts, which can form a docking area, and there is only one detection part, which is close to the middle area of ​​the docking area.

[0011] In the embodiment of the present application, a detection portion is formed by providing a detection coating on the outer wall of one of the first connection portions, so that the detection of the mating clearance can be realized, and the detection portion is located in the middle area of ​​the docking area. Taking the cross-sectional shape of the first connector and the second connector in the docking direction as a rectangle as an example, it is easy to understand that since the first connector is a rigid structure, if the first connection portion and the second connection portion located in the middle area can be in a normal connection state, then other areas can also be in a normal connection state to a large extent. Therefore, by providing a detection portion in the middle area, the detection of the mating clearance can be realized by a small number of detection portions.

[0012] In a possible implementation, there are multiple first connection parts, which can form a docking area, and there are multiple detection parts, which are located near the edge of the docking area.

[0013] In the embodiment of the present application, the docking of the first connector and the second connector along the docking direction is a rigid connection. When the detection portion located on the outside and the second connection portion located on the outside have a good matching clearance, the first connection portion located on the inside and the second connection portion located on the inside may also have a good matching clearance, so that the first connection portion and the second connection portion can maintain a normal connection state. Therefore, by arranging the detection coating on the first connection portion located on the outside, the connection state of the first connection portion and the second connection portion located on the outside can be detected, so that the detection coating does not need to be additionally arranged on the first connection portion located on the inside, that is, the connection state of the first connection portion and the second connection portion can be confirmed, which is conducive to saving the material cost of the detection coating and reducing the coating process.

[0014] In a possible implementation, a plurality of first connection portions are spaced apart along the first direction, and at least one detection portion is respectively provided near two ends of the docking area.

[0015] In the embodiment of the present application, when the plurality of first connection parts are distributed in one direction, a "I"-shaped docking area can be formed. By arranging the detection parts at the two ends of the docking area along the first direction, the connection state of the entire first connector and the second connector can be confirmed by the connection state of the first connector and the second connector at the end positions.

[0016] In a possible implementation, a plurality of first connection portions form a docking area having a circular cross-section, where the cross-section is a cross-section in the docking direction of the first connector and the second connector; wherein the plurality of detection portions are evenly distributed in the docking area, and the detection portions are close to the outer edge of the docking area.

[0017] In the embodiment of the present application, since the volume of the detection coating is relatively small, a detection coating can be set on any type of first connector to calculate the size of the fitting gap according to the target threshold value, so that the connection status of the first connector and the second connector can be confirmed according to the size of the fitting gap.

[0018] Among them, the docking area having a circular cross-section may mean that the shape formed by the first connection part located on the outer side of the docking area may be circular. In addition, multiple first connection parts may be evenly and spacedly distributed in the docking area. Among the multiple first connection parts located on the outer edge of the docking area, the outer wall of at least some of the first connection parts is provided with a detection coating and constitutes a detection part for detecting the connection state between the first connection part and the second connection part located on the outer edge of the docking area, so that the connection state between the first connector and the second connector can be confirmed according to the connection state between the first connection part and the second connection part located on the outer edge of the docking area.

[0019] In a possible embodiment, a plurality of first connection parts form a docking area with a polygonal cross-section, where the cross-section is a cross-section in the docking direction of the first connector and the second connector; wherein the plurality of detection parts are respectively located at the connection points of a plurality of adjacent sides of the polygonal cross-section of the docking area.

[0020] In an embodiment of the present application, the docking area having a polygonal cross-section may mean that the shape formed by the first connection portion located on the outside of the docking area may be a polygon. In addition, a plurality of first connection portions may be evenly and spacedly distributed in the docking area. This embodiment is described using a quadrilateral as an example of a polygon. It is easy to understand that when the first connection portion located at the four corners of the docking area has a good fitting clearance with the second connection portion, the first connector and the second connector may generally be in a normally connected state. Therefore, by providing a detection coating on the first connection portion located at the four corners of the docking area, it can be used to detect the fitting clearance between the first connection portion and the second connection portion at the four corners, thereby confirming the connection state of the first connector and the second connector.

[0021] In a possible implementation manner, the detection coating is a flexible metal layer.

[0022] In the embodiment of the present application, by setting the detection coating as a flexible metal layer, the second connection part can easily leave a wear mark on the detection coating of the detection part during the process of connecting the detection part to the second connection part. The matching clearance is calculated by the difference between the wear mark size and the target threshold value, thereby confirming the connection state of the first connector and the second connector. In addition, the flexible metal layer can not easily affect the transmission of the signal.

[0023] In a second aspect, an embodiment of the present application further provides a computing device, comprising a single board and a docking board in any of the above embodiments. The docking board comprises a second connector docked with the first connector of the single board, the second connector comprises a second connecting portion, and the second connecting portion is in contact with and connected to the first connecting portion.

[0024] In a possible implementation manner, the single board may be a service board, a switching network board, or a main control board; and the docking board may be a backplane.

[0025] In a third aspect, the embodiment of the present application further provides a method for determining the connection status of a connector, wherein a single board is docked with an opposite device, the single board includes a first connector, the first connector includes a first connecting portion, the outer wall of the first connecting portion is provided with a detection coating layer which can constitute a detection portion, and the number of the detection portions is at least one. The opposite device includes a second connector which can be docked with the first connector; the method may include:

[0026] Obtaining a size of a wear mark on a detection portion of the first connector, where the wear mark on the detection portion is generated by the first connector and the second connector being mated with each other;

[0027] Based on the size of the wear mark on the detection portion, the connection state between the first connector and the second connector is determined.

[0028] In the embodiment of the present application, since the second connection portion of the second connector can move a certain distance on the detection portion during the docking process between the first connector and the second connector, the second connection portion can form a wear mark on the detection coating of the detection portion. The size of the wear mark can indicate the relative movement distance of the second connection portion on the detection portion, so the connection state of the first connector and the second connector can be confirmed by the size of the wear mark.

[0029] The method for determining the connection status of the connector provided in the embodiment of the present application is simple to operate, convenient for operators to operate, and helps to reduce the difficulty of detection and improve the work efficiency in the confirmation process. In addition, since the volume of the detection coating is small, the detection coating can be set on any first connection part, which helps to improve the accuracy of the detection.

[0030] In a possible embodiment, the connection state includes a normal state and an abnormal state, the wear mark size may have a target threshold, and in the normal state, the difference between the wear mark size on the detection part and the target threshold is within a preset range; in the abnormal state, the difference between the wear mark size on the detection part and the target threshold is outside the preset range.

[0031] In an embodiment of the present application, the connection state includes two states: a normal state and an abnormal state. The detection standards under the normal state and the abnormal state can be set. When the first connector and the second connector are connected normally, the difference between the wear mark size on the detection part and the target threshold value can be within a preset interval. In other words, the first connector and the second connector can have a good fitting clearance, so that the first connector and the second connector can maintain a normal connection state. When the first connector and the second connector are connected abnormally, the difference between the wear mark size on the detection part and the target threshold value can be outside the preset interval. In other words, the fitting clearance between the first connector and the second connector is abnormal. At this time, the connection state of the first connector and the second connector may be skewed or over-pressured, etc.

[0032] In a possible implementation, based on the wear mark size on the detection part, the connection state between the first connector and the second connector is determined, including: the target threshold is D1, the wear mark size on the detection part is D2, and the fitting clearance D is the difference between the target threshold D1 and the wear mark size D2. When the fitting clearance D is within a preset interval, it is confirmed that the connection state between the first connector and the second connector is normal; when the fitting clearance D is outside the preset interval, it is confirmed that the connection state between the first connector and the second connector is normal.

[0033] In a possible implementation, the preset interval is determined based on a transmission rate of the first connector.

[0034] In the embodiment of the present application, different preset intervals can be determined based on the transmission rate of the first connector. When the transmission rate requirement is high, the range of the preset interval is smaller and the maximum value of the preset interval is also set smaller. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] Internet service providers, enterprise platforms, research institutions, etc. all need a lot of computing needs. The operating platform that carries storage, computing, and network needs is called a data center. A data center can include a computer room. There is at least one computing device in the computer room. The computing device can be a communication cabinet, a power cabinet, etc. Among them, the computing device can be a server, such as a liquid cooling service, an AI server, etc.

[0056] With the rise of big data, cloud computing and artificial intelligence (AI), the computing requirements of data centers and servers are getting higher and higher, and the exchange rate between server nodes and networks is also gradually increasing.

[0057] The computing equipment in the data center includes single boards. For example, switch boards, etc. When the single board is inserted into the computing equipment, the connector on the single board is docked with the connector on the opposite device. After the two connectors are docked, there may be a gap (Demating). The size of the gap has a great influence on the impedance. Too large a gap will cause impedance mutation, thereby affecting signal integrity and affecting the working reliability of the single board. At this time, the operator needs to take timely measures to reduce the gap to within the allowable target spacing threshold.

[0058] The embodiment of the present application provides a single board, and a first connector 120 for docking with other devices is provided on the circuit board 110 of the single board. The first connecting portion 121 of the first connector 120 is connected to the second connector 210 on the docking device, so that the first connector 120 and the second connector 210 can transmit signals. During the connection process between the first connector 120 and the second connector 210, they can move relative to each other for a distance along the docking direction X, so that the first connector 120 and the second connector 210 can have a good matching clearance. By providing a detection plating layer 1221 on the first connecting portion 121, based on the smaller volume of the detection plating layer 1221 itself, the detection plating layer 1221 can be arranged on any first connecting portion 121, and the arrangement position and arrangement range of the detection plating layer 1221 are not easily limited, which is conducive to improving the accuracy of the detection result. During the docking process between the first connector 120 and the second connector 210, the second connector 210 generates wear marks on the detection plating layer 1221. The operator can confirm the size of the fitting gap by detecting the length of the wear mark, and thus can confirm the connection state of the first connector 120 and the second connector 210 based on the size of the fitting gap.

[0059] The single board 100, the computing device 10 and the method for determining the connection status of the connector provided in the embodiment of the present application are described in detail below through specific implementation methods.

[0060] The present application embodiment provides a single board 100, see Figures 1 to 3 As shown, the single board 100 may include a circuit board 110 and a first connector 120. The first connector 120 is disposed on the circuit board 110. The first connector 120 may be used to dock with the second connector 210 of the opposite device. The first connector 120 includes a first connecting portion 121, and the first connecting portion 121 is used for signal transmission with the second connector 210. Among them, the outer wall of the first connecting portion 121 is provided with a detection coating 1221 to constitute a detection portion 122. The detection portion 122 may be used to detect the connection state of the first connector 120 and the second connector 210.

[0061] It should be noted that the outer wall of the first connecting part is provided with a detection coating to constitute the detection part, and the detection part is composed of the first connecting part and the detection coating arranged on the outer wall of the first connecting part. It can also be understood that the detection part includes the first connecting part and the detection coating.

[0062] The outer wall of the first connection portion 121 is provided with a detection coating 1221 to form a detection portion 122. In the embodiment of the present application, the number of the detection portion 122 can be at least one.

[0063] It should be noted that the embodiment of the present application does not limit the type of the single board 100. The single board 100 can be connected to the opposite device in a plug-in manner through the first connector 120. Exemplarily, the single board 100 is a business board 300, a switching network board 400 or a main control board 500. The business board 300 can also be called a line processing unit (LPU), a line card board and a line card. The switching network board 400 can also be called a switch fabric unit (SFU) and a switch card. The main control board 500 can also be called a main processing unit (MPU).

[0064] The circuit board 110 can be used as a carrier of the first connector 120, and the circuit board 110 can be a printed circuit board (PCB). The first connector 120 is used to dock with the second connector 210 of the opposite device. The type of the first connector 120 is not limited in the embodiment of the present application. For example, the first connector 120 can be a male connector, and the second connector 210 can be a female connector. Alternatively, the first connector 120 can be a female connector, and the second connector 210 can be a male connector. The number of the first connecting portion 121 can be multiple, so as to be used for signal transmission with the opposite device.

[0065] It is easy to understand that the position of the detection part 122 can affect the detection accuracy of the mating clearance. For example, when there are multiple detection parts 122, if the multiple detection parts 122 are evenly distributed at various positions of the first connector 120, multiple positions on the first connector 120 can be detected, so that the detection range can be expanded, thereby having better detection accuracy. If the multiple detection parts 122 are concentrated and offset on the first connector 120, the detection range of the first connector 120 is also concentrated in this area, and its detection accuracy is low.

[0066] In the embodiment of the present application, since the detection plating 1221 is a thin layer structure, the volume of the detection plating 1221 is small, and the detection plating 1221 is not easily limited by its own volume, nor is it easily limited by the space on the first connector 120. The detection plating 1221 can be provided on any first connecting portion 121, so the operator can set the position of the detection portion 122 according to the shape of the mating surface of the first connector 120 and the second connector 210, so as to achieve high-precision detection through a small number of detection portions 122. For example, according to the shape of the mating surface of the first connector 120 and the second connector 210, the detection portion 122 can be located in the middle position, or at the edge position, corner position, etc.

[0067] Moreover, compared with the method of arranging a distance sensor, the method of detecting the fitting gap by detecting the plating layer 1221 is less expensive. There is no need to set an additional fixing structure on the first connector 120 or the second connector 210. The detection method is simple and convenient, and can effectively improve the detection efficiency.

[0068] By providing the detection plating layer 1221 on the outer wall of the first connection portion 121 and forming the detection portion 122, during the docking process between the first connector 120 and the second connector 210, the second connector 210 can form a wear mark on the detection plating layer 1221 of the detection portion 122. Therefore, by detecting the size of the wear mark along the docking direction X, it can be used to confirm the connection state between the first connector 120 and the second connector 210.

[0069] It should be noted that when the first connector 120 is connected to the second connector 210, the second connector 210 can easily form a wear mark on the detection plating layer 1221 of the detection portion 122. In addition, the detection plating layer 1221 can also have the function of transmitting signals. In other words, the detection plating layer 1221 is arranged on the outer wall of the first connection portion 121, which can not easily affect the signal transmission between the first connector 120 and the second connector 210.

[0070] Specifically, the second connector 210 may also be provided with a second connection portion 211. The number of the second connection portions 211 may also be multiple. The second connection portion 211 and the first connection portion 121 may correspond one-to-one and be connected to each other, so as to realize signal transmission by connecting the first connection portion 121 and the second connection portion 211. It should be noted that the second connection portion 211 corresponds one-to-one to the first connection portion 121, including the second connection portion 211 corresponding to and connected to the first connection portion 121 provided with a detection coating 1221. During the docking process of the first connector 120 and the second connector 210 along the docking direction X, the first connection portion 121 and the second connection portion 211 move relative to each other, and the second connection portion 211 may form a wear mark on the detection coating 1221 of the detection portion 122. The size of the wear mark can represent the distance of the sliding contact of the second connection portion 211 on the first connection portion 121. Therefore, by measuring the size of the wear mark along the mating direction X, the contact position between the second connection portion 211 and the first connection portion 121 can be determined, thereby confirming the connection state between the first connector 120 and the second connector 210 .

[0071] In some examples, when the first connector 120 and the second connector 210 fit well, the second connection portion 211 can form a well-fitting wear scar size on the detection plating 1221. During the actual docking process, the second connection portion 211 can form an actual wear scar size on the first connection portion 121. For the convenience of description, the well-fitting wear scar size can be referred to as the target threshold. The actual wear scar size can be referred to as the wear scar size. Among them, the difference between the target threshold and the wear scar size is the fitting clearance. It is easy to understand that when the fitting clearance is 0, the wear scar size is equal to the target threshold, and the first connector 120 and the second connector 210 are in a normal connection state. When the fitting clearance is greater than or less than 0, the first connector 120 and the second connector 210 are in an abnormal connection state.

[0072] In some examples, the fitting clearance can also be an interval range, depending on the different requirements of the server node and the network exchange rate. For example, when the fitting clearance is within 0-0.5mm and can also meet the signal transmission rate, when the fitting clearance obtained by wear mark size detection is within 0-0.5mm, the first connector 120 and the second connector 210 can be in a normal connection state. Among them, the interval parameter of 0-0.5mm can be called a preset interval. It is easy to understand that when the fitting clearance obtained by wear mark size detection is outside the range of 0-0.5mm (that is, outside the preset interval), the first connector 120 and the second connector 210 are in an abnormal connection state.

[0073] It should be noted that the higher the exchange rate requirement, the smaller the fit clearance.

[0074] In summary, the operator can confirm the connection status of the first connector 120 and the second connector 210 based on the size of the wear marks on the detection layer 1221, so as to optimize and improve the structural design of the first connector 120 or the second connector 210, so that in actual applications, the first connector 120 and the second connector 210 can be normally connected to ensure the normal operation of the computing device 10.

[0075] Alternatively, in actual application, the first connector 120 and the second connector 210 may be docked first, and then the first connector 120 and the second connector 210 may be separated, and the wear scar size may be detected. By comparing the wear scar size with the target threshold, it is confirmed whether the fitting clearance between the first connector 120 and the second connector 210 is within a preset interval. If within the preset interval, the first connector 120 and the second connector 210 are in a normally connected state, and the computing device 10 may operate normally. If the fitting clearance is greater than or less than the preset interval value, it is necessary to readjust the connection state between the first connector 120 and the second connector 210 so that the fitting clearance between the first connector 120 and the second connector 210 can meet the integrity of the signal transmission of the high-speed link.

[0076] In some examples, the abnormal connection state between the first connector 120 and the second connector 210 may include that the first connector 120 and the second connector 210 are over-pressured or skewed. When the wear scar size on the detection plating 1221 is greater than the target threshold, and the fitting clearance is outside the preset interval, the first connector 120 and the second connector 210 are in an over-pressure state. Among the multiple detection parts 122 on the first connector 120, when the fitting clearance calculated based on the wear scar size on some of the detection parts 122 exceeds the preset interval, and the fitting clearance calculated based on the wear scar size on some of the detection parts 122 is located in the preset interval, the first connector 120 and the second connector 210 are in a skewed state. Therefore, through the detection part 122 of the embodiment of the present application, when the connection between the first connector 120 and the second connector 210 is abnormal, the specific abnormal state can be confirmed.

[0077] In some examples, the position and number of the detection parts 122 can be set according to the structure of the first connector 120 and the second connector 210, which is not limited in the present embodiment. It is easy to understand that the more the number of detection parts 122, the larger the range covered by the detection parts 122 on the first connector 120, and the larger the detection range, which is conducive to improving the accuracy of the detection results. Through the parameters detected by each detection part 122, the connection status at the corresponding position of each detection part 122 can be accurately confirmed, so that it is convenient for the operator to readjust the docking angle or force direction of the first connection part 121 and the second connection part 211, and then the first connection part 121 and the second connection part 211 can be adjusted to maintain a normal connection state.

[0078] In some achievable manners, there may be a plurality of first connection portions 121. The plurality of first connection portions 121 may form a docking area 120a, and there may be one detection portion 122. The detection portion 122 may be close to a middle area of ​​the docking area 120a.

[0079] In the embodiment of the present application, a detection portion 122 is formed by setting a detection coating 1221 on the outer wall of one of the first connection portions 121, so that the detection of the fitting gap can be realized, and the detection portion 122 is located in the middle area of ​​the docking area 120a. Taking the cross-sectional shape of the first connector 120 and the second connector 210 in the docking direction X as an example, it is easy to understand that since the first connector 120 is a rigid structure, if the first connection portion 121 and the second connection portion 211 located in the middle area can be in a normal connection state, then other areas can also be in a normal connection state to a large extent. Therefore, by setting a detection portion 122 in the middle area, the detection of the fitting gap can be realized by a small number of detection portions 122.

[0080] In some possible implementations, see Figures 4 to 6 As shown, the number of the first connection parts 121 in the embodiment of the present application is multiple. The multiple first connection parts 121 can form a docking area 120a. The number of the detection parts 122 can be multiple. The multiple detection parts 122 can be spaced and located near the edge of the docking area 120a.

[0081] In the embodiment of the present application, by providing multiple detection parts 122, more data parameters can be provided for detecting the matching gap to improve the detection accuracy. In addition, when there are multiple detection parts 122, it is also possible to judge whether the first connection part 121 and the second connection part 211 are in a skewed or over-pressed state by the size of the wear marks on different detection parts 122.

[0082] Specifically, see Figure 4a As shown, the docking of the first connector 120 and the second connector 210 along the docking direction X is a rigid connection. When the detection portion 122 located on the outside and the second connection portion 211 located on the outside have a good matching gap, the first connection portion 121 located on the inside and the second connection portion 211 located on the inside can also have a good matching gap D1, so that the first connection portion 121 and the second connection portion 211 can maintain a normal connection state. Therefore, by setting the detection plating 1221 on the first connection portion 121 located on the outside, the connection state of the first connection portion 121 and the second connection portion 211 located on the outside can be detected, so that the detection plating 1221 does not need to be additionally set on the first connection portion 121 located on the inside, that is, the confirmation of the connection state of the first connection portion 121 and the second connection portion 211 can be realized, which is conducive to saving the material cost of the detection plating 1221 and reducing the plating process.

[0083] In some possible implementations, see Figure 4As shown, the multiple first connection parts 121 of the embodiment of the present application can be arranged at intervals along the first direction Y. At least one detection part 122 is respectively arranged at both ends of the docking area 120a along the first direction Y. Among them, at least one detection part 122 can refer to two, three, four or even more.

[0084] In the embodiment of the present application, when the plurality of first connection portions 121 are distributed in one direction, a "I"-shaped docking area 120a can be formed. By arranging the detection portion 122 at the two ends of the docking area 120a along the first direction Y, the connection state of the entire first connector 120 and the second connector 210 can be confirmed by the connection state of the first connector 120 and the second connector 210 at the end positions.

[0085] When the docking area 120a forms an "I"-shaped docking area 120a, it is easy to understand that the two points near the end can form a stable connection mode. Therefore, when the first connector 120 and the second connector 210 are docked, if the first connection part 121 and the second connection part 211 can be in a normal connection state at both ends of the docking area 130a, the middle area can also be in a normal connection state to a large extent. Therefore, by setting two detection parts 122 at both ends of the docking area 130a, a smaller number of detection parts 122 can be used to detect the matching gap.

[0086] In some examples, the first connector 120 may be a gold finger connector. Figure 4 In the direction shown, among the multiple first connection parts 121 arranged at intervals along the first direction Y on the first connector 120, the surfaces of the first connection parts 121 located at the two ends can be provided with a detection plating layer 1221. The second connection part 211 of the second connector 210 can match the first connection part 121. When the first connector 120 and the second connector 210 are docked, the second connection part 211 can form a wear mark on the detection plating layer 1221, so that the matching clearance can be obtained through the wear mark size, and the connection state of the first connector 120 and the second connector 210 can be confirmed through the matching clearance.

[0087] In some examples, the first connection portion 121 may have two metal connection segments spaced apart along the mating direction X. The detection plating layer 1221 may be disposed on at least one of the metal connection segments.

[0088] In some examples, the gold finger may be in the form of, but not limited to, MCIO, UBC, etc.

[0089] In some examples, the number of the detection parts 122 may be, but is not limited to, two. When the number of the detection parts 122 is two, the two detection parts 122 may be located at two ends of the docking area 130a, respectively. Alternatively, the number of the detection parts 122 may be an even number, and when the number of the detection parts 122 is four, two detection parts 122 may be provided at two ends of the docking area 130a, respectively.

[0090] It is easy to understand that the more the number of detection parts 122 is, the more measurement data can be provided for the connection state of the first connector 120 and the second connector 210, which is conducive to improving the accuracy of the connection state confirmation result. However, the more the number of detection parts 122 is, the higher the material cost of the detection plating layer 1221 and the cost of the plating process are. Therefore, the number of detection parts 122 can be set according to parameters such as the type of the first connector 120 and the size of the docking area 120a.

[0091] In some possible implementations, see Figure 5 As shown, the plurality of first connection portions 121 of the embodiment of the present application may form a docking area 120a having a circular cross section, where the cross section is a cross section of the docking direction X of the first connector 120 and the second connector 210. The plurality of detection portions 122 are evenly distributed in the docking area 120a, and the detection portions 122 are close to the outer edge of the docking area 120a.

[0092] It should be noted that the circular cross section may refer to, but is not limited to, a standard circular cross section. The circular cross section may also refer to a closed curve formed by a plurality of arcs. For example, the circular cross section may also be an elliptical cross section, a waisted circular cross section, and the like.

[0093] In the embodiment of the present application, since the volume of the detection coating 1221 is relatively small, the detection coating 1221 can be set on any type of first connector 120 to calculate the size of the fitting gap according to the target threshold value, so that the connection status between the first connector 120 and the second connector 210 can be confirmed according to the size of the fitting gap.

[0094] Among them, the circular cross-section of the docking area 120a may mean that the shape formed by the first connection part 121 located on the outside of the docking area 120a may be circular. In addition, multiple first connection parts 121 may be evenly and spacedly distributed in the docking area 120a. Among the multiple first connection parts 121 located on the outer edge of the docking area 120a, the outer wall of at least part of the first connection parts 121 is provided with a detection coating 1221 and constitutes a detection part 122, which is used to detect the connection state between the first connection part 121 located on the outer edge of the docking area 120a and the second connection part 211, so that the connection state between the first connection part 121 located on the outer edge of the docking area 120a and the second connection part 211 can be confirmed.

[0095] In some examples, the plurality of detection units 122 may also be unevenly distributed in the docking area 120a. For example, when the operator performs focused detection on a local area of ​​the docking area 120a according to needs, a larger number of detection units 122 may be arranged in the local area, and a smaller number of detection units 122 may be arranged in other areas.

[0096] In some examples, the first connection portion 121 may be a PIN. The first connection portion 121 may extend along the mating direction X and extend into the second connector 210 to be connected to the second connection portion 211 of the second connector 210 .

[0097] In some examples, the number of the detection parts 122 may be at least three. For example, the number of the detection parts 122 may be three. The three detection parts 122 may be evenly distributed on the outer edge of the docking area 120a. Alternatively, the number of the detection parts 122 may be four or more. Four or more detection parts 122 may be evenly distributed on the outer edge of the docking area 120a.

[0098] Taking the number of the detection parts 122 as three as an example, by detecting the sizes of the wear marks on any two detection parts 122, the connection state of the first connection part 121 and the second connection part 211 in the area connected by the two detection parts 122 can be detected. Since three points can form a stable connection mode, if the three detection parts 122 can detect that the first connection part 121 and the second connection part 211 are in normal connection, it can be determined that the first connection part 121 and the second connection part 211 are in a stable and reliable normal connection state.

[0099] In some possible implementations, see Figure 6As shown, the multiple first connection parts 121 of the embodiment of the present application can form a docking area 120a with a polygonal cross section, and the cross section is a cross section of the first connector 120 and the second connector 210 in the docking direction X. Among them, the multiple detection parts 122 can be respectively located at the connection of multiple adjacent sides of the polygonal cross section of the docking area 120a.

[0100] It should be noted that the polygonal cross section may refer to a quadrilateral, such as a square, a rectangle, etc. The polygonal cross section may also refer to a pentagon, a hexagon, etc., which is not limited in this embodiment. When the polygonal cross section is a pentagon, the number of the detection parts 122 may be five.

[0101] Among them, the docking area 120a having a polygonal cross-section may mean that the shape formed by the first connection part 121 located on the outside of the docking area 120a may be a polygon. In addition, multiple first connection parts 121 may be evenly and spacedly distributed in the docking area 120a. This embodiment is described by taking the polygon as a quadrilateral as an example. It is easy to understand that when the first connection part 121 and the second connection part 211 located at the four corners of the docking area 120a have a good matching clearance, the first connector 120 and the second connector 210 can usually be in a normal connection state. Therefore, by setting a detection coating 1221 on the first connection part 121 located at the four corners of the docking area 120a, it can be used to detect the matching clearance between the first connection part 121 and the second connection part 211 at the four corners, so that the connection state of the first connector 120 and the second connector 210 can be confirmed.

[0102] Specifically, the first connector 120 and the second connector 210 are docked to form a wear mark on the detection portion 122 of the first connector 120, and then the first connector 120 and the second connector 210 can be separated. The wear mark size of the detection plating layer 1221 on the detection portion 122 at the four corners can be measured by the length testing instrument, so that the matching clearance between the first connection portion 121 and the second connection portion 211 can be obtained, and the connection state of the first connector 120 and the second connector 210 can be confirmed.

[0103] In some examples, the length measuring instrument may be a caliper, an optical rangefinder, etc., which is not limited in this embodiment.

[0104] In some achievable embodiments, the detection coating 1221 of the embodiment of the present application may be a flexible metal layer.

[0105] In the embodiment of the present application, by setting the detection plating layer 1221 as a flexible metal layer, the second connection part 211 can easily leave a wear mark on the detection plating layer 1221 of the detection part 122 during the process of connecting the detection part 122 with the second connection part 211. The matching clearance is calculated by the difference between the wear mark size and the target threshold value, thereby confirming the connection state of the first connector 120 and the second connector 210. In addition, the flexible metal layer can not easily affect the transmission of the signal.

[0106] In some examples, the flexible metal layer may be copper, tin, etc., which is not limited in this embodiment.

[0107] In some achievable embodiments, the thickness of the detection coating layer 1221 may be between 0.1 micrometers and 0.5 micrometers.

[0108] Among them, when the thickness of the detection plating 1221 is less than 0.1 micron, the thickness of the detection plating 1221 is too thin. After repeated plugging and unplugging tests, the detection plating 1221 is easily worn away, thereby affecting the accuracy of wear mark detection, and then easily affecting the accuracy of confirming the connection state of the first connector 120 and the second connector 210. When the thickness of the detection plating 1221 is greater than 0.5 micron, the thickness of the detection plating 1221 is too large, and the resistance of the second connecting portion 211 to forming wear marks on the first connecting portion 121 is large, which is easy to affect the smoothness of the first connector 120 and the second connector 210 during the docking and insertion process. Therefore, the above technical problems can be effectively solved by setting the thickness of the detection plating 1221 between 0.1 micron and 0.5 micron.

[0109] In some examples, taking the first connection portion 121 as a PIN needle as an example, the outer diameter of the detection portion 122 may be greater than or equal to the outer diameter of the first connection portion 121. When the outer diameter of the detection portion 122 is greater than the outer diameter of the first connection portion 121, the difference between the outer diameter of the detection portion 122 and the outer diameter of the first connection portion 121 is not easy to be too large. If the difference between the outer diameter of the detection portion 122 and the outer diameter of the first connection portion 121 is large, it is easy to have a poor connection between part of the first connection portion 121 and the second connection portion 211, which is easy to affect the integrity of signal transmission.

[0110] In some examples, the difference between the outer diameter of the detection portion 122 and the outer diameter of the first connection portion 121 may be within 0.5 micrometers.

[0111] In some examples, the outer diameter of the first connection portion 121 provided with the detection coating 1221 can be smaller than the outer diameters of the other first connection portions 121 , so that after the detection portion 122 is formed, the outer diameter of the detection portion 122 can be equal to or have a small difference with the outer diameters of the other first connection portions 121 .

[0112] The embodiment of the present application may further provide a computing device 10. The computing device 10 may include the single board 100 in any of the above embodiments.

[0113] In an embodiment of the present application, the single board 100 includes a first connector 120, and a detection part 122 is provided on the first connector 120. Therefore, when the single board 100 is docked with other docking devices, wear marks can be formed on the detection coating 1221 of the detection part 122 to confirm the connection status between the single board 100 and the other docking devices.

[0114] In some possible implementations, see Figure 7 and Figure 8 As shown, the opposite device connected to the single board 100 may be a docking board. The computing device 10 may also include a docking board. The docking board may have a second connector 210. The second connector 210 may have a second connecting portion 211. When the first connector 120 is docked with the second connector 210, the first connecting portion 121 is connected and contacted with the second connecting portion 211.

[0115] In some examples, the single board 100 may be a service board 300 , a switching network board 400 , or a main control board 500 . The docking board may be a backplane 600 .

[0116] For some examples, see Figure 7 As shown, the computing device 10 used by the single board 100 may adopt an orthogonal architecture, and the opposite-side device includes an opposite-side single board 200 , and the opposite-side single board 200 has a second connector 210 .

[0117] For example, the board 100 may be a service board 300 or a main control board 500, and the opposite board 200 may be a switching network board 400. Alternatively, the board 100 may be a switching network board 400, and the opposite board 200 may be a service board 300 or a main control board 500.

[0118] For some examples, see Figure 8 As shown, the computing device 10 used by the single board 100 may adopt a non-orthogonal architecture, and the opposite-side device includes a backplane 600 having a second connector 210 .

[0119] The present application may also provide a method for determining a connection state of a connector. The method may refer to a connection state between a first connector and a second connector.

[0120] The method may include the following steps:

[0121] First, the size of the wear mark on the detection portion 122 of the first connector 120 is obtained. The wear mark on the detection portion 122 is generated by the first connector 120 and the second connector 210 being mated.

[0122] In the process of docking the first connector 120 with the second connector 210 , wear marks may be generated on the detection plating layer of the detection portion 122 .

[0123] Then, the first connector 120 and the second connector 210 may be separated to measure the size of the wear mark on the detection plating layer of the detection portion 122 along the mating direction X.

[0124] After the wear marks are formed on the detection plating layer 1221 of the detection part 122, the first connector 120 and the second connector 210 can be separated to facilitate the operator to measure the size of the wear marks. The operator can measure the size of the wear marks on the detection part 122 using a measuring tool.

[0125] Finally, the connection state between the first connector 120 and the second connector 210 may be determined based on the size of the wear mark on the detection portion 122 .

[0126] Specifically, the connection state of the embodiment of the present application may include a normal state and an abnormal state. The wear mark size may have a target threshold. In the normal state, the difference between the wear mark size on the detection part and the target threshold may be within a preset interval. In the abnormal state, the difference between the wear mark size on the detection part and the target threshold may be outside the preset interval.

[0127] In the embodiment of the present application, since the second connection portion 211 of the second connector 210 can move a certain distance on the detection portion 122 during the docking process between the first connector 120 and the second connector 210, the second connection portion 211 can form a wear mark on the detection plating layer 1221 of the detection portion 122. The size of the wear mark can indicate the relative movement distance of the second connection portion 211 on the detection portion 122, so that the connection state of the first connector 120 and the second connector 210 can be confirmed by the size of the wear mark.

[0128] The method for determining the connection status of the connector provided in the embodiment of the present application is simple to operate, convenient for operators to operate, and helps to reduce the difficulty of detection and improve the work efficiency during the confirmation process. In addition, since the volume of the detection coating 1221 is small, the detection coating 1221 can be set on any first connection part 121, which helps to improve the accuracy of detection.

[0129] Among them, the connection state includes two states: a normal state and an abnormal state. The detection standards in the normal state and the abnormal state can be set. When the first connector 120 and the second connector 210 are connected normally, the difference between the wear mark size on the detection part 122 and the target threshold value can be within a preset interval. In other words, the first connector 120 and the second connector 210 can have a good matching clearance, so that the first connector 120 and the second connector 210 can maintain a normal connection state. When the first connector 120 and the second connector 210 are abnormally connected, the difference between the wear mark size on the detection part 122 and the target threshold value can be outside the preset interval. In other words, the matching clearance between the first connector 120 and the second connector 210 is abnormal. At this time, the connection state of the first connector 120 and the second connector 210 may be skewed or over-pressured.

[0130] In some examples, the preset interval may be a specific parameter value or an interval range, which is not limited in this embodiment.

[0131] In some possible implementations, see Figure 2 and Figure 3 As shown, in the embodiment of the present application, the target threshold of the wear mark size can be set to D1. When the wear mark size actually detected on the detection unit 122 is D2, D1-D2 represents the fitting clearance D between the first connector 120 and the second connector 210. If the fitting clearance D is within the preset interval, it can be confirmed that the connection state between the first connector 120 and the second connector 210 is normal. If the fitting clearance D is outside the preset interval, it can be confirmed that the connection state between the first connector 120 and the second connector 210 is normal.

[0132] In some examples, when there are multiple detection parts 122, after the first connector 120 and the second connector 210 are docked along the docking direction X and then separated, wear marks may be generated on each detection part 122. Therefore, the wear mark size D2 on each detection part 122 may be measured respectively, and each wear mark size D2 may be subtracted from the target threshold value D1 to obtain the fitting clearance D. When each fitting clearance D is within the preset interval, it can be confirmed that the first connector 120 and the second connector 210 are in a normal state. When the fitting clearance D obtained on any of the detection parts 122 is not within the preset interval, it can be confirmed that the first connector 120 and the second connector 210 are in an abnormal state.

[0133] In some achievable ways, in the embodiments of the present application, the preset interval may be determined based on the transmission rate of the first connector 120 .

[0134] In the embodiment of the present application, different preset intervals may be determined based on the transmission rate of the first connector 120. When the transmission rate requirement is high, the range of the preset interval is smaller, and the maximum value of the preset interval is also set smaller.

[0135] In the description of the embodiments of the present application, 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, or it can be an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements.
