Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to a connector, an electronic component and an electronic equipment. Background Art

[0002] Electronic devices usually include multiple electronic components, including circuit boards and boards, and circuit boards and boards are connected by signals. There are many ways to achieve signal connection between circuit boards and chips, and a more common one includes using a connector to connect circuit boards and boards.

[0003] With the continuous evolution of electronic devices, the number of transmitted signals is increasing and the speed is getting faster. As an important part of signal transmission, connectors also have an important impact on the operating speed of electronic devices. Therefore, higher requirements are also placed on the speed of connector signal transmission. Summary of the invention

[0004] The present application provides a connector, an electronic component and an electronic device to increase the rate at which the connector transmits signals and enrich the application scenarios of the electronic device.

[0005] In the first aspect, the present application provides a connector, which includes a housing and a terminal. Among them; the terminal is fixed to the housing, and the two ends of the terminal are respectively connected to the electronic device to realize signal transmission between the two electronic devices. The two ends of the terminal include a first contact and a second contact, respectively, and the terminal is fixedly installed on the housing in the area between the first contact and the second contact. The above-mentioned first contact and the second contact are respectively connected to the electronic device to realize signal transmission between the two electronic devices. In specific implementation, the above-mentioned first contact can be used to connect with the opposite end connector, and the first contact and the opposite end connector are detachably connected. For ease of understanding, it is considered that the edge of the area where the above-mentioned terminal is fixed to the housing in the direction of the first contact is a fixed point, and specifically, the terminal is in a free state starting from the fixed point. The area between the above-mentioned terminal and the first contact is a force arm area, which can be deformed with the connection between the connector and the opposite end connector, and the first contact and the contact of the opposite end connector are reliably in contact. Further, the terminal of the above-mentioned connector includes a signal terminal and a ground terminal, and the ground terminal can be used as a reference ground for the signal, and can also play a role in signal shielding, reduce crosstalk between signals, and help improve the rate at which the connector transmits signals. The connector also includes a first common ground component, which is electrically connected to the ground terminal. Specifically, at least two ground terminals can be electrically connected to the same first common ground component in the force arm area. In this solution, at least two ground terminals are connected to the same common ground component in the force arm area through the first common ground component, and the arm length of the ground terminal extending from the common ground point is shorter. Specifically, the resonance point generated by the ground terminal is increased to outside the working frequency band, which is beneficial to reducing signal crosstalk and improving the rate at which the connector transmits signals. In addition, the first common ground component set in this solution has little effect on the mechanical properties of the force arm area of ​​the terminal.

[0006] In a specific technical solution, the housing includes a plurality of mounting grooves, and the terminals are fixedly mounted in the mounting grooves.

[0007] In a further technical solution, the connector further includes a second common ground component, which is fixed to the housing, and at least two ground terminals are electrically connected to the second common ground component. This solution increases the common ground point of the ground terminals, which is conducive to further increasing the frequency of the resonance point generated by the ground terminals and reducing crosstalk between signals.

[0008] The connection method between the first common ground component and the ground terminal is not limited. In an optional technical solution, the first common ground component and the ground terminal electrically connected to each other are an integrated structure. The structure of the connector is relatively simple, and the connection between the first common ground component and the ground terminal is relatively reliable, and the installation process is also relatively reliable.

[0009] In another optional technical solution, the first common ground component is an independent structural member. Specifically, the first common ground component includes a plurality of slots, which are snap-fitted with the force arm area of ​​the ground terminal. Thus, an electrical connection between the first common ground component and the ground terminal is achieved. In this solution, the position where the first common ground component is snap-fitted with the ground terminal can be adjusted according to demand, and the resonance point generated by the ground terminal can be flexibly adjusted, which is conducive to enriching the application scenarios of the connector in the embodiment of the present application.

[0010] When the above-mentioned first common ground component is specifically set, the first common ground component can be located at a position between the fixed point of the ground terminal and the first contact. In a preferred technical solution, for the same ground terminal, the above-mentioned first common ground component is located at the midpoint between the fixed point of the ground terminal and the first contact. Specifically, it can be considered that for the same ground terminal, the distance between the first common ground component and the fixed point of the ground terminal is equal to the distance between the first common ground component and the first contact. The arm lengths of the ground terminals extending from the first common ground component are relatively close and are not too long, which is beneficial to increase the frequency of the resonance point generated by the ground terminal and improve the rate at which the connector transmits signals.

[0011] When the above-mentioned connector is specifically assembled, the ground terminal and the signal terminal are usually located in the same plane, and the first common ground component is only used to be electrically connected to the ground terminal, but not connected to the signal terminal. Therefore, the first common ground component includes a first avoidance groove, which is opposite to the signal terminal and is used to avoid the signal terminal. In addition, in order to avoid the above-mentioned first common ground component, the housing of the connector also includes a second avoidance groove, which is opposite to the first common ground component and is used to avoid the first common ground component. In particular, the first common ground component is located at the force arm of the ground terminal, and will swing with the swing of the ground terminal. Therefore, the second avoidance groove has a certain avoidance space so that the first common ground component can swing in the above-mentioned second avoidance groove.

[0012] In order to simplify the installation of the connector, the above-mentioned shell includes a fixing component and a shell body, and the fixing component is fixedly connected to the shell body to form the shell of the connector. The terminal is fixedly installed on the fixing component, and specifically, the fixing component can have an installation groove, and the terminal is installed in the above-mentioned installation groove. The fixing component is fixedly installed on the shell body, and the first common ground component can avoid the fixing component, and the second avoidance groove of the shell for avoiding the first common ground component can be located in the shell body. This solution can first fix the signal terminal and the ground terminal to the fixing component, and the fixing component can be designed to be smaller, which is conducive to achieving the fixed connection between the terminal and the fixing component, and then the fixing component is fixedly connected to the shell body. The connection process of the fixing component and the shell body is relatively simple, which is conducive to simplifying the assembly process of the connector.

[0013] In a technical solution, the signals transmitted by the connector include high-speed signals and low-speed signals, wherein the transmission rate of the high-speed signals is higher than the transmission rate of the low-speed signals. It includes a high-speed signal transmission area and a low-speed signal transmission area, and the rate of signal transmission in the high-speed signal transmission area is higher than the rate of signal transmission in the low-speed signal transmission area. It can be considered that the high-speed signal transmission area is used to transmit high-speed signals, and the low-speed signal transmission area is used to transmit low-speed signals. All ground terminals in the same high-speed signal transmission area are electrically connected to the same first common ground component. In this solution, the ground terminal in the high-speed signal area generates a higher resonant frequency, which is higher than the operating frequency of the connector, which is conducive to reducing the impact on the high-speed signal and improving the transmission rate and effect of the high-speed signal.

[0014] In the second aspect, the present application also provides an electronic component, which includes a circuit board, an electronic device and the connector provided in the first aspect. The connector is arranged on the circuit board, specifically so that the second contact is electrically connected to the circuit board; in addition, the electronic device includes a counterpart connector, and the connector provided by the present application is connected to the counterpart connector, specifically so that the first contact is electrically connected to the counterpart connector. In this solution, the circuit board and the electronic device are connected by a connector, and since the crosstalk generated by the ground terminal is small, it is beneficial to improve the rate at which the connector transmits signals, thereby realizing high-speed transmission of signals between the circuit board and the electronic device.

[0015] In a third aspect, the present application further provides an electronic device, the electronic device comprising a housing and the electronic component provided in the second aspect, the electronic component being arranged in the housing. In this solution, the rate of signal transmission in the electronic device is relatively high, which is conducive to adapting to the continuous evolution of electronic devices and transmitting more and faster signals.

[0032] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings.

[0033] The terms used in the following embodiments are only for the purpose of describing specific embodiments and are not intended to be limiting of the present application.

The terms "include", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized.

[0035] To facilitate understanding of the connector, electronic components, and electronic devices provided in the embodiments of the present application, their application scenarios are first introduced below.

[0036] The electronic device in the embodiment of the present application can be a communication device (such as a router), a computing device (such as a server), a network device (such as a switch) or a storage device (such as a storage array) and other electronic devices, especially electronic devices with high-speed signal transmission requirements. The present application does not limit the specific type of electronic device, as long as the electronic device needs to use a connector to connect the chip to the circuit board, the technical solution provided by the present application can be adopted.

[0037] For ease of description, the embodiments of the present application are described by taking the electronic device as a server as an example. Figure 1 is a schematic diagram of the structure of an electronic device in an embodiment of the present application, such as Figure 1 As shown, the electronic device may include a housing 100 and an electronic component 200 disposed in the housing 100. Specifically, when the electronic device is a cabinet server, the housing 100 may be understood as a cabinet of the cabinet server, and the electronic component 200 may include a node. Figure 1 As shown, the electronic assembly 200 specifically includes a circuit board 210, an electronic device 220 and a connector 230, and the connector 230 is connected between the circuit board 210 and the electronic device 220 to realize signal transmission between the electronic device 220 and the circuit board 210. In specific applications, the electronic device 220 can include a counterpart connector, and one end of the connector 230 can be welded and fixed to the circuit board 210, and the other end can be connected to the counterpart connector. Specifically, the counterpart connector can be plugged into the connector 230, so as to realize the connection between the electronic device 220 and the circuit board 210. In a specific embodiment, the electronic device can be a board or a cable connector.

[0038] In a specific embodiment, a chip 211 may also be provided on the circuit board 210, and the chip 211 is electrically connected to the circuit board 210. The electronic device 220 is a board, which is connected to the connector 230, and then connected to the chip 211 signal to form the electronic component 200. As the rate of signals transmitted in electronic devices becomes higher and higher, the rate of signals transmitted between the board 220 and the circuit board 210 is gradually increased. Specifically, the chip 211 provided on the circuit board 210 may be an artificial intelligence (AI) chip or a graphics processing unit (GPU), which is used to perform computationally intensive or memory-intensive business data processing such as artificial intelligence or high performance computing (HPC).

[0039] Figure 2 This is a schematic diagram of the structure of a connector in an embodiment of the present application. Figure 3 FIG. 1 is a schematic diagram of a partial explosion structure of a connector in an embodiment of the present application. Figure 2 and Figure 3 As shown, the connector 230 in the embodiment of the present application includes a housing 1 and a terminal 2, and the housing 1 can be specifically a housing 1 made of plastic material. Specifically, the two ends of the terminal 2 include a first contact 21 and a second contact 22, respectively, wherein the first contact 21 and the second contact 22 are respectively used to connect with the circuit board 210 and the electronic device 220. For example, the first contact 21 is used to electrically connect with the electronic device 220. Specifically, the first contact 21 can be connected to the opposite connector connected to the electronic device 220, and the connector 230 is a detachable end at the end where the first contact 21 is located; the second contact 22 is used to electrically connect with the circuit board 210, thereby realizing signal transmission between the electronic device 220 and the circuit board 210. The terminal 2 is fixedly connected to the housing 1 in the area between the first contact 21 and the second contact 22, that is, the middle area of ​​the terminal 2 is fixedly connected to the housing 1. For ease of understanding, it is considered that in the area where the terminal 2 is fixedly connected to the housing 1, the edge facing the first contact 21 is the fixed point 23, and the area of ​​the terminal 2 between the fixed point 23 and the first contact 21 is the force arm area 24. Specifically, the fixed point 23 may correspond to a specific physical structure, or may not correspond to a specific physical structure, and only refers to a specific position on the terminal 2. When the opposite connector is connected to the connector 230, it abuts against the first contact 21, causing the force arm area 24 to deform and generate elastic force, and the force arm area 24 begins to deform from the fixed point 23.

[0040] Please continue to refer to Figure 2 and Figure 3 In a specific embodiment, the terminal 2 includes a signal terminal 25 and a ground terminal 26, wherein the signal terminal 25 is used to transmit signals, and the ground terminal 26 is used as a reference ground for the signal, or can be used as a shielding structure to reduce signal crosstalk between different signal terminals 25, which is beneficial to improving the signal transmission efficiency of the connector 230. The connector 230 also includes a first common ground component 3, which is electrically connected to the ground terminal 26. Specifically, at least two ground terminals 26 can be electrically connected to the same first common ground component 3 in the arm region 24. In this solution, at least two ground terminals 26 are connected to the same ground through the first common ground component 3 in the arm region 24, and the arm length of the ground terminal 26 extending from the common ground point is shorter. Specifically, the resonance point generated by the ground terminal 26 is increased to outside the working frequency band, which is beneficial to reducing signal crosstalk and improving the rate at which the connector 230 transmits signals. In addition, the first common ground component 3 set in this solution has little effect on the mechanical properties of the arm region 24 of the terminal 2.

[0041] Figure 4 Schematic diagram of the comparison between the connector of the embodiment of the present application and the connector in the prior art, as shown in FIG. Figure 4As shown, the solid line in the figure represents the resonance schematic diagram of the ground terminal of the connector 230 in the embodiment of the present application, and the dotted line in the figure represents the resonance schematic diagram of the ground terminal without the first common ground component in the embodiment of the present application. Figure 4 As shown, when the first common ground component is not provided, the ground terminal of the connector 230 has a resonance point near 26 GHz to 27 GHz, so it is difficult for the connector 230 to transmit high-speed signals, or the rate of the signal transmitted by the connector 230 is limited and difficult to further improve. In the technical solution of the present application, a first common ground component is provided, so that multiple ground terminals are shared, and then the resonance point of the ground terminal of the connector 230 is increased, thereby improving the rate at which the connector 230 transmits signals to meet the current demand for high-speed signal transmission.

[0042] In a specific embodiment, in order to install the terminal 2 , the housing 1 includes a plurality of installation slots 11 , and the terminal 2 is fixedly assembled in the installation slots 11 .

[0043] In a further embodiment, the connector 230 may further include a second common ground component, which is fixed to the housing 1, and at least two of the above-mentioned ground terminals 26 are electrically connected to the second common ground component. Specifically, all of the ground terminals 26 may be electrically connected to the above-mentioned second common ground component. In this solution, the common ground point of the ground terminal 26 is increased, which is conducive to further increasing the frequency of the resonance point generated by the ground terminal 26 and reducing the crosstalk between signals.

[0044] In a specific embodiment, all the ground terminals 26 in the connector 230 can be electrically connected via a first common ground component 3 , so that all the ground terminals 26 can be grounded in the force arm region 24 .

[0045] In another specific embodiment, the signal transmitted by the connector 230 includes a high-speed signal and a low-speed signal, wherein the transmission rate of the high-speed signal is higher than the transmission rate of the low-speed signal, which can also be understood as the signal rates transmitted by the connector 230 are different. Therefore, the connector 230 may include multiple areas, specifically including a high-speed signal transmission area and a low-speed signal transmission area, the high-speed signal transmission area is used to transmit high-speed signals, and the signal terminal 25 in this area is a first signal terminal; the low-speed signal transmission area is used to transmit low-speed signals, and the signal terminal 25 in this area is a second signal terminal. The rate at which the first signal terminal transmits a signal is higher than the rate at which the second signal terminal transmits a signal. In specific applications, the ground terminal 26 of each high-speed signal transmission area can be electrically connected through the same first common ground component 3. It can also be understood that in each high-speed signal transmission area, the ground terminal 26 adjacent to the first signal terminal is electrically connected to the same first common ground component 3. This solution can enable a small number of necessary ground terminals 26 to achieve common ground in the arm area 24, and the preparation process is relatively simple, which is conducive to reducing costs.

[0046] The specific formation method of the first common ground component 3 is not limited in the present application. In a specific embodiment, the first common ground component 3 and the ground terminal 26 electrically connected to each other are an integrally formed structure. In this solution, the structure of the connector 230 is relatively simple, and the connection between the first common ground component 3 and the ground terminal 26 is relatively reliable, and the installation process is also relatively reliable.

[0047] Specifically, the above-mentioned integrally formed ground terminal 26 and first common ground component 3 can be prepared by a stretching process. The preparation of the two structures is completed by a one-time preparation process, and the elasticity of the force arm region 24 is good.

[0048] Figure 5 Schematic diagram of the structure of the ground terminal and the first common ground component in the embodiment of the present application. Figure 5 As shown, in another embodiment, the first common ground component 3 is an independent component, and the first common ground component 3 includes a plurality of slots, which are snap-fitted with the ground terminal 26, so as to realize the connection between the ground terminal 26 and the first common ground component 3. In this solution, the ground terminal 26 and the first common ground component 3 can be prepared independently, and the preparation process is relatively simple, and then the first common ground component 3 is snap-fitted with the ground terminal 26. In addition, in this solution, the position where the first common ground component 3 is snap-fitted with the ground terminal 26 can be adjusted according to needs, and the resonance point generated by the ground terminal 26 can be flexibly adjusted, which is conducive to enriching the application scenarios of the connector 230 in the embodiment of the present application.

[0049] In a specific embodiment, when the first common ground component 3 is provided in the force arm 24 of the ground terminal 26, the first common ground component 3 can be located at the midpoint between the first contact 21 and the fixed point 23 of the ground terminal 26. Then the distance between the first contact 21 of the ground terminal 26 and the first common ground component 3 is equal to the fixed point 23 of the same ground terminal 26. Here, the equality is equal in design, not absolutely equal. The distance between the position of the first common ground component 3 and the first contact 21 and the distance between the first common ground component 3 and the fixed point 23 of the same ground terminal 26 may be slightly different due to installation errors. In other words, the first common ground component 3 is connected to the area between the first contact 21 and the fixed point 23 of the ground terminal 26, so that the arm length of the ground terminal 26 extending from the first common ground component 3 is relatively close and not too long, which is conducive to increasing the frequency of the resonance point generated by the ground terminal 26 and improving the signal transmission rate of the connector 230.

[0050] In another specific embodiment, the connector 230 may further include at least two first common ground components 3, and the at least two first common ground components 3 are electrically connected to the force arm region 24 of the ground terminal 26. This solution is conducive to increasing the common ground point of the ground terminal 26. The arm length of the ground terminal 26 extending from the common ground point is shorter, which can further increase the frequency of the resonance point generated by the ground terminal 26, reduce the crosstalk between the ground terminals 26, and improve the signal transmission rate of the connector 230.

[0051] When the at least two first common ground components 3 are specifically arranged, the at least two first common ground components 3 can be evenly arranged in the ground terminal 26 between the fixed point 23 and the first contact 21 , or in other words, the at least two first common ground components 3 are evenly arranged in the force arm area 24 of the ground terminal 26 .

[0052] Please refer to Figure 2 and Figure 3 Since the contact of the signal terminal 25 of the connector 230 and the contact of the ground terminal 26 are approximately located in the same plane, the force arm area 24 of the signal terminal 25 and the force arm area 24 of the ground terminal 26 are approximately located in the same plane. To this end, the first common ground component 3 includes a first avoidance groove 31, and the first avoidance groove 31 is opposite to the signal terminal 25, so that there is no contact between the signal terminal 25 and the first common ground component 3. The above-mentioned shell 1 includes a second avoidance groove 12, and the second avoidance groove 12 is opposite to the first common ground component 3, which is used to avoid the first common ground component 3. In order to set the above-mentioned first avoidance groove 31, the first common ground component 3 protrudes from the force arm area 24 of the ground terminal 26, and when the connector 230 is connected to the opposite connector, the force arm will swing. In the technical solution of the present application, the second avoidance groove 12 of the shell 1 can avoid the first common ground component 3, so that the first common ground component 3 can swing in the above-mentioned second avoidance groove 12.

[0053] In a specific embodiment, please refer to Figure 2 and Figure 3 The housing 1 includes a fixing component 13 and a housing body 14, and the terminal 2 is fixed to the fixing component 13. Specifically, the mounting groove 11 can be located in the fixing component 13, that is, the signal terminal 25 and the ground terminal 26 are both fixed to the fixing component 13, and the fixing point 23 is located in the fixing component 13. The fixing component 13 is fixedly installed in the housing body 14, and the second avoidance groove 12 is located in the housing body 14. In this solution, the signal terminal 25 and the ground terminal 26 can be fixedly connected to the fixing component 13 first, and the fixing component 13 can be designed to be smaller, which is conducive to the fixed connection between the terminal 2 and the fixing component 13, and then the fixing component 13 is fixedly connected to the housing body 14. The connection process between the fixing component 13 and the housing body 14 is relatively simple, which is conducive to simplifying the assembly process of the connector 230.

[0054] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
