Description

Technical Field

[0001] This application relates to the field of data communication technology, specifically to a connection architecture and communication device. Background Technology

[0002] Communication devices such as servers and switches include circuit boards with connectors for communication connections with other circuit boards and other electronic components. In related technologies, the layout and design of connectors on circuit boards are often inefficient, leading to wasted space.

[0003] Therefore, how to provide a solution to overcome or alleviate the above-mentioned defects remains a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a connection architecture and a communication device, wherein the connection architecture has first connectors installed on both sides of the normal direction of the first circuit board, which can reduce space waste and increase the number and density of the first connectors.

[0005] In a first aspect, embodiments of this application provide a connection architecture, which can be specifically applied to communication devices such as switches, routers, and servers. The connection architecture includes a first circuit board, a connection module, and a component to be connected. The connection module includes a first connection unit and a second connection unit. The first connection unit includes two first connectors, which are respectively mounted on opposite sides of the first circuit board in the normal direction. The second connection unit includes a second connector, which is mounted on the component to be connected. The first connector and the second connector are connected to achieve a communication connection between the first circuit board and the component to be connected.

[0006] In the above scheme, the first connection unit of the connection module has a split structure, including two first connectors. The two first connectors are respectively installed on both sides of the normal direction of the first circuit board, so that the space on both sides of the normal direction of the first circuit board can be used to install the first connectors, which can reduce space waste and increase the number of first connectors, thereby improving the layout density and electrical connection efficiency of the first connectors. Furthermore, under the condition that the number of transmission links remains unchanged, splitting the first connection unit into two first connectors can also effectively reduce the size of each first connector along the normal direction of the first circuit board, thereby reducing the existence of excessively long transmission links, which is also conducive to reducing transmission loss and improving signal fidelity and anti-interference.

[0007] As can be seen, the embodiments of this application provide a technical solution that can provide first connectors on both sides of the first circuit board in the normal direction. Its structural design is novel, enriching the installation methods of the first connector and improving its installation flexibility. At the same time, because the size of a single first connector is relatively small, it can also reduce the manufacturing cost of the first connector, thereby enhancing the product's market competitiveness.

[0008] In some possible implementations, the second connecting unit includes a second connector, and both first connectors of the first connecting unit are connected to the second connector of the second connecting unit. In this way, the number of second connectors included in the second connecting unit can be relatively small, making it easier to connect the second connecting unit and the component to be connected.

[0009] In some possible implementations, the component to be connected is a connecting cable. In this implementation, the connection architecture provided in this application embodiment can achieve a communication connection between the first circuit board and the connecting cable. Specifically, the connecting cable can be a high-speed cable, etc., for transmitting high-speed signals.

[0010] In some possible implementations, the component to be connected is a second circuit board, and the second connector connects to the second circuit board along its normal direction; the normal direction of the second circuit board and the normal direction of the first circuit board form an angle. In this implementation, the connection architecture provided in this application embodiment can achieve a communication connection between the first circuit board and the second circuit board.

[0011] In some possible implementations, the connection architecture further includes a third circuit board, which is disposed on the side of the second circuit board opposite to the first circuit board. The third circuit board and the second circuit board are also connected via a connection module. In this implementation, the connection architecture provided in this application embodiment can achieve communication connections between the first circuit board, the second circuit board, and the third circuit board.

[0012] In some possible implementations, first connectors are mounted on both sides of the normal direction of the third circuit board, and second connectors are mounted on the second circuit board. The two first connectors of the third circuit board can be plugged into the second connectors of the second circuit board to achieve a communication connection between the second and third circuit boards. Alternatively, first connectors can be mounted on both sides of the normal direction of the second circuit board, and second connectors can be mounted on the third circuit board. Then, the second connectors and the first connectors can be connected together, which can also achieve a communication connection between the second and third circuit boards.

[0013] In some possible implementations, the normals of the third circuit board and the first circuit board are parallel to each other. In this case, the connection architecture provided in this embodiment is a non-orthogonal architecture. Alternatively, the normals of the third circuit board and the first circuit board may form an angle, such as 90 degrees. In this case, the connection architecture provided in this embodiment is an orthogonal architecture.

[0014] In some possible implementations, the second connector has a second connection pin, and the connection method between the second connection pin and the second circuit board includes at least one of crimping, soldering, snap-fitting, riveting, and bonding.

[0015] In some possible implementations, the first connector has a first connection pin, which is connected by at least one of the following connection methods: crimping, soldering, snap-fitting, riveting, and bonding.

[0016] Secondly, embodiments of this application also provide a communication device, which may be, for example, a switch, a router, a server, etc. The communication device may include a casing, a power supply, a heat sink, and a connection architecture, and the connection architecture is specifically the connection architecture involved in the first aspect and any of the various implementations of the first aspect.

[0028] To enable those skilled in the art to better understand the technical solutions of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] In the description of the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0030] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation", "connection" and "linking" should be interpreted broadly. For example, "linking" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0031] In the description of embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0032] Please refer to Figure 1 , Figure 1 This is a schematic diagram of a connection architecture in related technologies.

[0033] like Figure 1 As shown, in related technologies, the connection architecture 1000' includes a first circuit board 1100', a second circuit board 1200', and a connection module 1300'.

[0034] The connection module 1300' includes a first connector 1310' and a second connector 1320'. The first connector 1310' is connected to the first circuit board 1100' and is located on the normal side of the first circuit board 1100'. The first connector 1310' may be provided with at least two transmission links 1311', which can be arranged at intervals. The second connector 1320' can be connected to the second circuit board 1200' along the normal direction, and the first connector 1310' and the second connector 1320' can be connected. In this way, a communication connection relationship can be established between the first circuit board 1100' and the second circuit board 1200'.

[0035] However, in the above scheme, the first connectors 1310' are all located on one side of the normal direction of the first circuit board 1100', resulting in wasted space on the other side of the normal direction of the first circuit board 1100'. This limits the number of first connectors 1310', resulting in a relatively low layout density of the first connectors 1310'. Furthermore, since the first connectors 1310' are only located on one side of the first circuit board 1100', the dimensions of the first connectors 1310' along the normal direction of the first circuit board 1100' can be relatively large, allowing for some transmission links 1311' (such as...) to be larger. Figure 1 The dimensions shown in the bold double-dotted line will be relatively long, and the transmission loss will also be relatively large.

[0036] Please refer to Figures 2-4 , Figure 2 This is a schematic diagram of the connection architecture provided in an embodiment of this application; Figure 3 This is a schematic diagram of another connection architecture provided in the embodiments of this application; Figure 4 This is a schematic diagram of another connection architecture provided in the embodiments of this application.

[0037] Regarding the aforementioned technical issues, such as Figure 2 As shown, this application embodiment provides a connection architecture 1000, which can be applied to communication devices such as switches, routers, and servers. The connection architecture 1000 includes a first circuit board 1100, a connection module 1200, and a component to be connected 1300.

[0038] The connection module 1200 includes a first connection unit 1210 and a second connection unit 1220. The first connection unit 1210 includes two first connectors 1211, which are respectively mounted on opposite sides of the normal direction of the first circuit board 1100. Each first connector 1211 is provided with a transmission link 1211A. The second connection unit 1220 includes a second connector 1221, which is connected to the component 1300 to be connected. The connection between the first connector 1211 and the second connector 1221 establishes a communication connection between the first circuit board 1100 and the component 1300.

[0039] Using the above solution, in this embodiment of the application, the first connection unit 1210 of the connection module 1200 is set as a split structure, including two first connectors 1211, and the two first connectors 1211 are respectively installed on both sides of the normal direction of the first circuit board 1100, so that the space on both sides of the normal direction of the first circuit board 1100 can be used to install the first connectors 1211, which can reduce space waste and increase the number of first connectors 1211, thereby improving the layout density and electrical connection efficiency of the first connectors 1211.

[0040] Furthermore, while maintaining the same number of transmission links 1211A, splitting the first connection unit 1210 into two first connectors 1211 can effectively reduce the size of each first connector 1211 along the normal direction of the first circuit board 1100, thereby reducing the presence of excessively long transmission links 1211A and also helping to reduce transmission loss. For example, it can be compared with... Figure 1 and Figure 2 , Figure 1 The first connector 1310' includes four transmission links 1311', which are arranged sequentially. This results in the two transmission links 1311' closer to the top being relatively long, leading to relatively high transmission loss. However, in this embodiment, the first connectors 1211 are respectively arranged on both sides of the normal direction of the first circuit board 1100, and each first connector 1211 can be provided with only two transmission links 1211A, allowing the size of each first connector 1211 along the normal direction of the first circuit board 1100 to be relatively small. Figure 1 The relatively long transmission link 1311′ of medium size can be omitted, which can significantly reduce signal transmission loss.

[0041] As can be seen, the present application provides a technical solution that can provide a first connector 1211 on both sides of the first circuit board 1100 in the normal direction. Its structural design is novel, which can enrich the installation form of the first connector 1211 and improve the installation flexibility of the first connector 1211. At the same time, since the size of a single first connector 1211 is relatively small, it can also reduce the manufacturing cost of the first connector 1211, so as to enhance the market competitiveness of the product.

[0042] Here, the embodiments of this application do not limit the specific types of the first connector 1211 and the second connector 1221 described above. In practical applications, those skilled in the art can select them according to specific needs, as long as they can meet the requirements of use. For example, the first connector 1211 can be a bent connector, and the second connector 1221 can be a straight connector.

[0043] In some implementations, such as Figure 2 As shown, the second connecting unit 1220 may include one second connector 1221, and both first connectors 1211 of the first connecting unit 1210 may be connected to the second connector 1221 of the second connecting unit 1220. In this way, the number of second connectors 1221 included in the second connecting unit 1220 can be relatively small, which makes it easier to connect the second connecting unit 1220 and the component 1300 to be connected.

[0044] As can be seen, in some other implementations of this application, the second connecting unit 1220 may also include two second connectors 1221. Both of these second connectors 1221 can be connected to the component 1300 to be connected, and each of these two second connectors 1221 can be connected to two first connectors 1211 respectively. In this way, the first connectors 1211 and the second connectors 1221 have a one-to-one assembly relationship, which can largely avoid the situation of incorrect assembly of the first connectors 1211 and the second connectors 1221.

[0045] In some implementations, such as Figure 2 As shown, the component to be connected 1300 can be, for example, a second circuit board 1310. In this implementation, the connection architecture 1000 provided in this embodiment can achieve a communication connection between the second circuit board 1310 and the first circuit board 1100. In specific assembly, the second connector 1221 can connect to the second circuit board 1310 along its normal direction. The normal direction of the second circuit board 1310 and the normal direction of the first circuit board 1100 can form an angle, such as 90 degrees.

[0046] For ease of description, in this embodiment, a first direction X, a second direction Y, and a third direction Z can be defined. The first direction X is the normal to the first circuit board 1100; the second direction Y is the normal to the second circuit board 1310; either the first direction X or the second direction Y can form an angle with the third direction Z, such as 90 degrees.

[0047] In some implementations, such as Figure 3 and Figure 4 As shown, the connection architecture 1000 provided in this application embodiment may further include a third circuit board 1400. Along the second direction Y, the third circuit board 1400 may be located on the side of the second circuit board 1310 opposite to the first circuit board 1100, and the third circuit board 1400 may also be connected through the aforementioned connection module 1200.

[0048] In one specific embodiment, the first connecting unit 1210 may be mounted on the third circuit board 1400. Specifically, the two first connectors 1211 of the first connecting unit 1210 may be mounted on opposite sides of the normal direction of the third circuit board 1400, and the second connector 1221 of the second connecting unit 1220 may be mounted on the second circuit board 1310. Then, the first connectors 1211 and the second connector 1221 may be connected. In another specific embodiment, the first connecting unit 1210 may be mounted on the second circuit board 1310. Specifically, the two first connectors 1211 of the first connecting unit 1210 may be mounted on opposite sides of the normal direction of the second circuit board 1310, and the second connector 1221 of the second connecting unit 1220 may be mounted on the third circuit board 1400. Then, the first connectors 1211 and the second connector 1221 may be connected. The matching relationship in quantity between the first connectors 1211 and the second connector 1221 can be referred to the foregoing description and will not be repeated here.

[0049] Here, the embodiments of this application do not limit the setting direction of the third circuit board 1400. In practical applications, those skilled in the art can set it according to specific needs, as long as it can meet the requirements of use. For example, see Figure 3 The normal direction of the third circuit board 1400 and the normal direction of the first circuit board 1100 can be parallel, that is, the normal direction of the third circuit board 1400 can also be the first direction X; in this case, the connection architecture provided in this embodiment can be a non-orthogonal architecture. For example, see... Figure 4 Furthermore, the normal of the third circuit board 1400 can also form an angle with the normal of the first circuit board 1100. In detail, the normal of the third circuit board 1400 can be a third direction Z; the aforementioned angle can be 90 degrees. In this case, the connection architecture provided in this application embodiment is an orthogonal architecture.

[0050] Furthermore, the embodiments of this application do not limit the specific types of the first circuit board 1100, the second circuit board 1310, and the third circuit board 1400. In practical applications, those skilled in the art can configure them according to specific needs, as long as the requirements for use are met. For example, the first circuit board 1100 can be a service board, the second circuit board 1310 can be a backplane, and the third circuit board 1400 can be a stencil. As another example, one of the first circuit board 1100, the second circuit board 1310, and the third circuit board 1400, such as the first circuit board 1100, can also be a substrate for carrying chips.

[0051] In some implementations, the first connector 1211 may have a first connection pin 1211B, and the second connector 1221 may have a second connection pin 1221A. Both the first connection pin 1211B and the second connection pin 1221A may be connected by at least one of the following connection methods: crimping, welding, snap-fitting, riveting, bonding, etc.

[0052] Please refer to Figure 5 , Figure 5 This is a diagram showing the connection structure between the first connection pin and the first circuit board 1100.

[0053] like Figure 5 As shown, taking the connection between the first connecting pin 1211B and the first circuit board 1100 as an example, the first connecting pin 1211B may have a large portion 1211B1, and the first circuit board 1100 may be provided with a mounting hole 1110. The first connector 1211 can be press-fitted towards the first circuit board 1100 using a press-fitting fixture, so that the first connecting pin 1211B can be inserted and assembled into the mounting hole 1110, and the large portion 1211B1 can form a tight fit with the inner wall of the mounting hole 1110, so as to achieve an interference fit between the first connecting pin 1211B and the mounting hole 1110, thereby realizing the press-fit connection between the first connecting pin 1211B and the first circuit board 1100.

[0054] Please refer to Figure 6 , Figure 6 This is a schematic diagram of another connection architecture provided in the embodiments of this application.

[0055] In some implementations, such as Figure 6 As shown, the component to be connected 1300 can also be a connecting cable 1320. The connecting cable 1320 can be connected to the second connector 1221, and the communication connection between the connecting cable 1320 and the first circuit board 1100 can be realized through the connection between the second connector 1221 and the first connector 1211.

[0056] This application provides a communication device, which may be, for example, a switch, a router, a server, etc. The communication device may include a casing, a power supply, a heat sink, and the connection architecture 1000 involved in the aforementioned implementations. Since the aforementioned connection architecture 1000 already has the above-mentioned technical effects, the communication device having the connection architecture 1000 should also have similar technical effects, which will not be elaborated here.

[0057] This document uses specific examples to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make several improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
