Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of computing devices, and in particular, to a connector and a computing device. Background Art

[0002] High-speed connectors are the key path and key components for data transmission and data exchange. As the transmission rate of high-speed signals increases, higher and higher requirements are placed on the transmission performance of high-speed connectors. Among them, the grounding method of the female connector is an important factor affecting the signal quality.

[0003] At present, each ground terminal in the connector is usually grounded independently. However, the independent grounding of the ground terminal will make the signal return path longer and the crosstalk between signals more serious. It can only meet the transmission requirements of low-speed signals and is difficult to meet the transmission requirements of high-speed signals. Therefore, how to improve the quality of high-speed signal transmission has become an urgent problem to be solved. Utility Model Content

[0004] The embodiments of the present application provide a connector and a computing device, which can effectively improve the signal backflow effect and reduce signal crosstalk.

[0005] The present application provides a connector, comprising a first grounding terminal and a second grounding terminal arranged adjacent to each other;

[0006] At least one of the first grounding terminal and the second grounding terminal is provided with a spring portion, the spring portion abuts against the other of the first grounding terminal and the second grounding terminal, and the first grounding terminal and the second grounding terminal are electrically connected through the spring portion;

[0007] One of the first grounding terminal and the second grounding terminal further has a grounding terminal, and both the first grounding terminal and the second grounding terminal are grounded through the grounding terminal.

[0008] In the embodiment of the present application, the first ground terminal and the second ground terminal are electrically connected through the spring portion, and the first ground terminal and the second ground terminal are grounded together through the ground terminal. In this way, the signal on the signal terminal can be refluxed through two paths, the first ground terminal and the second ground terminal, which can effectively improve the reflux effect of the signal. In addition, the signal crosstalk between adjacent signal terminal pairs can be reduced, thereby improving the integrity of the signal.

[0009] In a possible implementation, the first grounding terminal includes a first thin sheet portion and the elastic sheet portion, the elastic sheet portion is located on a side of the first thin sheet portion close to the second grounding terminal and extends outward relative to a side of the first thin sheet portion close to the second grounding terminal, and the elastic sheet portion and the first thin sheet portion are an integrated structure;

[0010] And / or, the second grounding terminal includes a second thin sheet portion and the spring sheet portion, the spring sheet portion is located on a side of the second thin sheet portion close to the first grounding terminal, and extends outward relative to a side of the second thin sheet portion close to the first grounding terminal, and the spring sheet portion and the second thin sheet portion are an integrated structure.

[0011] Taking the setting of the spring sheet part on the second grounding terminal as an example, the integrated structure of the second thin sheet part and the spring sheet part can effectively reduce or avoid the situation where the spring sheet part falls off, and can effectively improve the firmness and reliability of the connection between the spring sheet part and the second thin sheet part, which helps to improve the reliability and stability of the electrical connection between the first grounding terminal and the second grounding terminal, thereby effectively ensuring the stability of signal return.

[0012] In a possible implementation, the first sheet portion includes a first sheet body and a first sheet bending body, the first sheet body is located at two ends of the first sheet bending body, and the first sheet bending body protrudes from the plane where the first sheet body is located, and the elastic sheet portion is connected to the first sheet bending body;

[0013] And / or, the second thin sheet portion includes a second thin sheet body and a second thin sheet bending body, the second thin sheet body is located at both ends of the second thin sheet bending body, and the second thin sheet bending body protrudes from the plane where the second thin sheet body is located, and the elastic sheet portion is connected to the second thin sheet bending body.

[0014] Taking the arrangement of the spring sheet portion on the second grounding terminal as an example, since the spring sheet portion is connected to the second thin sheet bending body and the second thin sheet bending body protrudes from the plane where the second thin sheet body is located, the spring sheet portion also protrudes from the second thin sheet body. Among them, the second thin sheet body in the second grounding terminal is located in the same plane as the first grounding terminal, so the spring sheet portion is also higher than the first grounding terminal, so that the lower surface of the spring sheet portion is close to the upper surface of the first grounding terminal. In this way, it is convenient for the lower surface of the spring sheet portion to contact the upper surface of the first grounding terminal to achieve electrical connection. It helps to increase the abutting contact area between the spring sheet portion and the first grounding terminal, and improve the firmness and stability of the abutment between the spring sheet portion and the first grounding terminal.

[0015] In a possible implementation, the elastic sheet portion is arranged at an angle to the first sheet bending body, and the elastic sheet portion is offset in a direction close to the second ground terminal;

[0016] And / or, the elastic sheet portion and the second sheet bending body are arranged at an angle, and the elastic sheet portion is offset in a direction close to the first ground terminal.

[0017] Taking the example of setting a spring sheet part on the second grounding terminal, when the spring sheet part is grounded to the first grounding terminal, the first grounding terminal has an upward force on the spring sheet part, and the spring sheet part is in an elastic deformation state. Therefore, the spring sheet part has a large downward rebound force. The rebound force can prompt the spring sheet part to press toward the first grounding terminal, which helps to increase the reliability and firmness of the abutment between the spring sheet part and the first grounding terminal, and improve the reliability and stability of the electrical connection between the first grounding terminal and the second grounding terminal.

[0018] In a possible implementation, the angle between the spring portion and the first sheet bending body is approximately 185° to 189°;

[0019] The included angle between the spring portion and the second sheet bending body is approximately 185° to 189°.

[0020] Taking the setting of the spring piece part on the second grounding terminal as an example, this can increase the elastic force of the spring piece part during the contact process with the first grounding terminal, help increase the reliability and firmness of the abutment between the spring piece part and the first grounding terminal, and improve the reliability and stability of the electrical connection between the first grounding terminal and the second grounding terminal.

[0021] In a possible implementation, the spring piece portion includes a spring piece body and a spring piece bending body connected to each other;

[0022] The spring sheet body is connected to the first thin sheet portion through the spring sheet bending body, and the spring sheet bending body is arranged at an angle to the spring sheet body and the first thin sheet portion respectively, so that the spring sheet body protrudes from the plane where the first thin sheet portion is located, and the spring sheet body abuts against the second ground terminal;

[0023] And / or, the spring sheet body is connected to the second thin sheet portion through the spring sheet bending body, and the spring sheet bending body is arranged at an angle to the spring sheet body and the second thin sheet portion respectively, so that the spring sheet body protrudes from the plane where the second thin sheet portion is located, and the spring sheet body abuts against the first ground terminal.

[0024] Taking the second grounding terminal as an example, the distance between the spring body and the first grounding terminal can be closer, which can effectively increase the contact area between the spring body and the first grounding terminal and improve the reliability and stability of the contact between the spring body and the first grounding terminal.

[0025] In a possible implementation, the angle between the spring body and the spring bent body is about 85° to 89°. This can increase the elastic force during the contact between the spring body and the first ground terminal, help increase the reliability and firmness of the abutment between the spring body and the first ground terminal, and improve the reliability and stability of the electrical connection between the first ground terminal and the second ground terminal, thereby effectively improving the reliability and stability of signal return.

[0026] In a possible implementation, a first hollow portion is formed on the first thin sheet portion, the first hollow portion penetrates the first thin sheet portion in the thickness direction of the first thin sheet portion, and the shape of the elastic sheet portion matches the shape of the first hollow portion; one end of the elastic sheet portion abuts against the second grounding terminal, and the other end of the elastic sheet portion is connected to an inner wall of one side of the first hollow portion close to the second grounding terminal; in the thickness direction of the first thin sheet portion, at least a portion of the elastic sheet portion overlaps with the first thin sheet portion;

[0027] And / or, a second hollow portion is provided on the second thin sheet portion, the second hollow portion penetrates the second thin sheet portion in the thickness direction of the second thin sheet portion, and the shape of the spring sheet portion is adapted to the shape of the second hollow portion; one end of the spring sheet portion abuts against the first grounding terminal, and the other end of the spring sheet portion is connected to an inner wall of one side of the second hollow portion close to the first grounding terminal; in the thickness direction of the second thin sheet portion, at least part of the spring sheet portion overlaps with the second thin sheet portion.

[0028] Taking the second grounding terminal as an example, the spring part can be formed by using the material of the second grounding terminal itself, and no additional material for forming the spring part is required outside the second grounding terminal, which can reduce the material used for the second grounding terminal and reduce the material cost of the second grounding terminal.

[0029] In a possible implementation, the first sheet portion is further provided with a first edge pressing body, the first edge pressing body is located on a side of the first hollow portion close to the second grounding terminal, and in a thickness direction of the first sheet portion, the first edge pressing body and the second grounding terminal are located on the same side of the spring sheet portion;

[0030] And / or, the second thin sheet portion is also provided with a second edge clamping body, the second edge clamping body is located on the side of the second hollow portion close to the first grounding terminal, and in the thickness direction of the second thin sheet portion, the second edge clamping body and the first grounding terminal are located on the same side of the spring sheet portion.

[0031] In a possible implementation, the first sheet portion is further provided with a first edge pressing body, the first edge pressing body is located on a side of the first hollow portion close to the second grounding terminal, and in a thickness direction of the first sheet portion, the first edge pressing body and the second grounding terminal are respectively located on two opposite sides of the elastic sheet portion;

[0032] And / or, the second thin sheet portion is also provided with a second edge clamping body, the second edge clamping body is located on a side of the second hollow portion close to the first grounding terminal, and in the thickness direction of the second thin sheet portion, the second edge clamping body and the first grounding terminal are respectively located on two sides of the spring sheet portion opposite to each other.

[0033] Taking the second grounding terminal as an example, the second edge pressing body can limit the spring piece part, and can press the spring piece part in the direction close to the first grounding terminal to limit the spring piece part from moving in the direction away from the first grounding terminal. This can effectively reduce or avoid loosening or separation between the spring piece part and the first grounding terminal, and can effectively improve the reliability and stability of the abutment between the spring piece part and the first grounding terminal.

[0034] In a possible implementation, the width of the first edge-holding body is approximately 1 mm to 2 mm; and / or the width of the second edge-holding body is approximately 1 mm to 2 mm.

[0035] This can increase the structural strength of the second edge clamping body, enable the second edge clamping body to provide a more stable clamping force for the spring piece part, effectively reduce or avoid the second edge clamping body from breaking and causing the leaf structure to fail, and help improve the structural stability of the second edge clamping body and the spring piece part.

[0036] In a possible implementation, there are two spring pieces, which are spaced and arranged in parallel. This can prevent one of the spring pieces from being disconnected, thereby preventing the first grounding terminal from being disconnected from the second grounding terminal, and can reduce the probability of the first grounding terminal and the second grounding terminal being disconnected, which helps to increase the reliability and stability of the electrical connection between the first grounding terminal and the second grounding terminal.

[0037] In a possible implementation, the second grounding terminal has the grounding end, the length of the second grounding terminal is greater than the length of the first grounding terminal, and the width of the second grounding terminal is greater than the width of the first grounding terminal;

[0038] Alternatively, the first grounding terminal has the grounding end, the length of the first grounding terminal is greater than the length of the second grounding terminal, and the width of the first grounding terminal is greater than the width of the second grounding terminal.

[0039] Taking the second ground terminal as an example, the signal on the first ground terminal can flow to the second ground terminal and return through the ground terminal on the second ground terminal. This can effectively increase the size of the signal return path and effectively improve the efficiency of signal return.

[0042] In one possible implementation, the computing device is a server. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0066] The embodiment of the present application provides a computing device, which may be a server, a switch, a high-performance computing (HPC) or other device with computing functions.

[0067] The computing device may include a circuit board, and devices disposed on the circuit board, such as a central processing unit (CPU), dual inline memory modules (DIMM), a graphics processing unit (GPU), a network card, a peripheral component interconnect express (PCIE) card, a complex programmable logic device (CPLD), and a baseboard manager controller (BMC).

[0070] Figure 1 A schematic diagram of the structure of a connector provided in an embodiment of the present application.

[0071] The present application provides a connector. The connector may be a high-speed connector, which may be provided in a server and may be used to transmit high-speed signals. For example, a high-speed signal may refer to a signal with a transmission rate greater than 15 Gbps. For example, the connector may be used to transmit SerDes signals, PCIE signals, etc. Figure 1 As shown, the connector 100 may include a first grounding terminal 110 and a second grounding terminal 120 that are adjacently disposed. The first grounding terminal 110 and the second grounding terminal 120 may be disposed in parallel.

[0072] The first grounding terminal 110 and the second grounding terminal 120 respectively have a first end 111 and a second end 121 for plugging. In some examples, the connector 100 may be a female connector, and the connector 100 may be connected to a male connector. The first end 111 may be an end of the first grounding terminal 110 close to the male connector, and the second end 121 may be an end of the second grounding terminal 120 close to the male connector. The first end 111 and the second end 121 may be electrically connected to the male terminal on the male connector, so that the connector 100 is electrically connected to the male connector, so that the connector 100 and the male connector can realize the transmission of circuits and signals.

[0073] In some examples, the connector 100 may further include a signal terminal (not shown in the figure), and the signal terminal may be arranged adjacent to the first ground terminal 110 and the second ground terminal 120. For example, the connector 100 may include a plurality of transmission units, each of which includes a first ground terminal 110, a first signal terminal, a second signal terminal, and a second ground terminal 120 arranged in sequence. The plurality of transmission units are arranged in sequence, and each transmission unit includes two signal terminals and two ground terminals, so that the plurality of first ground terminals 110, signal terminals, and second ground terminals 120 may be arranged alternately.

[0074] For example, in the alternately arranged structure, any two adjacent signal terminals (such as the first signal terminal and the second signal terminal) can be used together to transmit differential signals to form a differential signal terminal pair, and two grounding terminals (such as the first grounding terminal 110 and the second grounding terminal 120) are arranged between two adjacent differential signal terminal pairs. A plurality of grounding terminals and a plurality of signal terminals are alternately arranged to form the connector 100.

[0075] The signal terminal has a first signal terminal and a second signal terminal, the first signal terminal is used to be electrically connected to the male connector, and the second signal terminal is used to be electrically connected to the circuit board. The signal terminal can be docked with the male signal terminal on the male connector to transmit signals. The signal terminal can achieve reflow through the adjacent ground terminal (the first ground terminal 110 or the second ground terminal 120).

[0076] Exemplarily, the connector 100 may further include a housing 130 , and the first ground terminal 110 , the second ground terminal 120 and the signal terminal may all be disposed in the housing 130 .

[0077] Continue to see Figure 1As shown, at least one of the first ground terminal 110 and the second ground terminal 120 may be provided with a spring portion 122, and the spring portion 122 is used to electrically connect the first ground terminal 110 and the second ground terminal 120. The spring portion 122 may abut against the other of the first ground terminal 110 and the second ground terminal 120. The first ground terminal 110 and the second ground terminal 120 may be electrically connected through the spring portion 122.

[0078] In one example, the first grounding terminal 110 is provided with a spring piece portion 122, and the spring piece portion 122 can abut against the second grounding terminal 120, so that the first grounding terminal 110 and the second grounding terminal 120 can be electrically connected through the spring piece portion 122. In another example, the second grounding terminal 120 is provided with a spring piece portion 122, and the spring piece portion 122 can abut against the first grounding terminal 110, so that the first grounding terminal 110 and the second grounding terminal 120 can be electrically connected through the spring piece portion 122.

[0079] In another example, the first grounding terminal 110 and the second grounding terminal 120 are both provided with a spring portion 122. The spring portion 122 on the first grounding terminal 110 can abut against the second grounding terminal 120, and the spring portion 122 of the second grounding terminal 120 can abut against the first grounding terminal 110. The first grounding terminal 110 and the second grounding terminal 120 can overlap with each other through the two spring portions 122, thereby being electrically connected through the two spring portions 122.

[0080] One of the first grounding terminal 110 and the second grounding terminal 120 may also have a grounding terminal 123. The first grounding terminal 110 and the second grounding terminal 120 may both be grounded through the grounding terminal 123. The grounding terminal 123 is used to be electrically connected to the circuit board. In the case where the first grounding terminal 110 has the grounding terminal 123, the grounding terminal 123 is arranged opposite to the first end 111. In the case where the second grounding terminal 120 has the grounding terminal 123, the grounding terminal 123 is arranged opposite to the second end 121. In the case where one of the first grounding terminal 110 and the second grounding terminal 120 is provided with a spring piece 122, the grounding terminal 123 and the spring piece 122 may be located on the same grounding terminal, or may also be located on different grounding terminals.

[0081] In one example, when the first ground terminal 110 is provided with a spring portion 122 and the first ground terminal 110 has a ground terminal 123, the ground terminal 123 may be located at an end of the first ground terminal 110 away from the first end 111. At this time, the signal on the second ground terminal 120 may flow to the first ground terminal 110 through the spring portion 122, and reflux through the ground terminal 123 on the first ground terminal 110, so that the first ground terminal 110 and the second ground terminal 120 may both realize signal reflux through the ground terminal 123.

[0082] In another example, when the first ground terminal 110 is provided with a spring portion 122, and the second ground terminal 120 has a ground terminal 123, the ground terminal 123 may be located at an end of the second ground terminal 120 away from the second end 121. At this time, the signal on the first ground terminal 110 may flow to the second ground terminal 120 through the spring portion 122, and reflux through the ground terminal 123 on the second ground terminal 120, so that the first ground terminal 110 and the second ground terminal 120 can both realize signal reflux through the ground terminal 123.

[0083] In another example, when the second ground terminal 120 is provided with a spring portion 122, and the second ground terminal 120 has a grounding end 123, the grounding end 123 may be located at an end of the second ground terminal 120 away from the second end 121. In this case, the signal on the first ground terminal 110 may flow to the second ground terminal 120 through the spring portion 122, and reflux through the grounding end 123 on the second ground terminal 120, so that the first ground terminal 110 and the second ground terminal 120 can both realize signal reflux through the grounding end 123.

[0084] In another example, when the second ground terminal 120 is provided with a spring portion 122, and the first ground terminal 110 has a ground terminal 123, the ground terminal 123 may also be located at an end of the first ground terminal 110 away from the first end 111. In this case, the signal on the second ground terminal 120 may flow to the first ground terminal 110 through the spring portion 122, and reflux through the ground terminal 123 on the first ground terminal 110, so that the first ground terminal 110 and the second ground terminal 120 may both realize signal reflux through the ground terminal 123.

[0085] In this way, the high-speed signal on the signal terminal can be refluxed through the first ground terminal 110 and the second ground terminal 120 at the same time, so that the signal can have more reflux paths, which can effectively improve the reflux effect of the signal and reduce signal crosstalk.

[0086] In the embodiment of the present application, the first ground terminal 110 and the second ground terminal 120 are electrically connected through the spring portion 122, and the first ground terminal 110 and the second ground terminal 120 are grounded together through the ground terminal 123. In this way, the signal on the signal terminal can be refluxed through two paths, the first ground terminal 110 and the second ground terminal 120, which can effectively improve the reflux effect of the signal. In addition, the signal crosstalk between adjacent signal terminal pairs can be reduced, and the integrity of the signal can be improved.

[0087] In addition, by providing a spring portion 122 on at least one of the first grounding terminal 110 and the second grounding terminal 120, and electrically connecting the first grounding terminal 110 and the second grounding terminal 120 through the spring portion 122, the electrical connection between the first grounding terminal 110 and the second grounding terminal 120 can be achieved without providing accessories separately. In this way, the number of components in the connector 100 can be reduced, the assembly process of the connector 100 can be simplified, and the production efficiency of the connector 100 can be improved.

[0088] Continue to see Figure 1 As shown, the following takes the second grounding terminal 120 provided with the elastic sheet portion 122 as an example, the second grounding terminal 120 may include a second thin sheet portion 124 and the elastic sheet portion 122, and the second thin sheet portion 124 and the elastic sheet portion 122 may be an integrated structure. The elastic sheet portion 122 is located on a side of the second thin sheet portion 124 close to the first grounding terminal 110, and extends outward relative to a side of the second thin sheet portion 124 close to the first grounding terminal 110.

[0089] For example, the first ground terminal 110 and the second ground terminal 120 can be made by cutting. In the process of making the second ground terminal 120 by cutting, the elastic sheet portion 122 can be cut out on, for example, a metal sheet, so that the elastic sheet portion 122 can extend toward the first ground terminal 110 relative to the second thin sheet portion 124, so as to abut against the first ground terminal 110.

[0090] By making the second thin sheet portion 124 and the spring sheet portion 122 an integrated structure, the situation where the spring sheet portion 122 falls off can be effectively reduced or avoided, and the firmness and reliability of the connection between the spring sheet portion 122 and the second thin sheet portion 124 can be effectively improved, which helps to improve the reliability and stability of the electrical connection between the first grounding terminal 110 and the second grounding terminal 120, thereby effectively ensuring the stability of signal return.

[0091] Figure 2 for Figure 1 View from the A direction, Figure 3 for Figure 1 The view from the B direction, Figure 4 A schematic diagram of the partial structure of the first second grounding terminal provided in an embodiment of the present application.

[0092] See also Figure 2 and Figure 3 As shown, in a possible implementation, the second sheet portion 124 may include a second sheet body 1241 and a second sheet bending body 1242. Figure 4 As shown, the second sheet body 1241 may be located at both ends of the second sheet bending body 1242 , and the second sheet bending body 1242 may protrude from the plane where the second sheet body 1241 is located, and the elastic sheet portion 122 may be connected to the second sheet bending body 1242 .

[0093] Specifically, for example, the metal sheet can be bent by a bending process to form a second sheet bending body 1242 protruding from the second sheet body 1241. The elastic sheet portion 122 can be connected to the second sheet bending body 1242 and extend outward relative to the second sheet bending body 1242 to form the second grounding terminal 120.

[0094] Since the spring piece 122 is connected to the second sheet bending body 1242 and the second sheet bending body 1242 protrudes from the plane where the second sheet body 1241 is located, the spring piece 122 also protrudes from the second sheet body 1241. Among them, the second sheet body 1241 in the second grounding terminal 120 and the first grounding terminal 110 are located in the same plane, so the spring piece 122 is also higher than the first grounding terminal 110, so that the lower surface of the spring piece 122 is close to the upper surface of the first grounding terminal 110. In this way, it is convenient for the lower surface of the spring piece 122 to contact with the upper surface of the first grounding terminal 110 to achieve electrical connection, which helps to increase the contact area between the spring piece 122 and the first grounding terminal 110, and improve the firmness and stability of the contact between the spring piece 122 and the first grounding terminal 110.

[0095] Correspondingly, when the first grounding terminal is provided with an elastic sheet portion, the first grounding terminal may include a first thin sheet portion and an elastic sheet portion, the elastic sheet portion may be located on a side of the first thin sheet portion close to the second grounding terminal, and extend outward relative to a side of the first thin sheet portion close to the second grounding terminal, and the elastic sheet portion and the first thin sheet portion may be an integrated structure. The first thin sheet portion may include a first thin sheet body and a first thin sheet bending body, the first thin sheet body may be located at both ends of the first thin sheet bending body, and the first thin sheet bending body may protrude from the plane where the first thin sheet body is located, and the elastic sheet portion may be connected to the first thin sheet bending body.

[0096] Specifically, the structure of the spring piece portion provided on the first grounding terminal may be set with reference to the structure of the spring piece portion provided on the second grounding terminal, which will not be described in detail here.

[0097] Figure 5A schematic diagram of the angle between the spring portion and the thin sheet bending body provided in an embodiment of the present application.

[0098] Among them, see Figure 5 As shown, the spring sheet portion 122 and the second thin sheet bending body 1242 can be set at an angle. The spring sheet portion 122 can be offset in the direction close to the first grounding terminal 110. That is, the spring sheet portion 122 can have a deflection angle in the direction close to the first grounding terminal 110. Specifically, when the spring sheet portion 122 is in contact with the first grounding terminal 110, the first grounding terminal 110 exerts an upward force on the spring sheet portion 122, and the spring sheet portion 122 is in an elastic deformation state, so the spring sheet portion 122 has a large downward rebound force. The rebound force can cause the spring sheet portion 122 to press in the direction of the first grounding terminal 110, which helps to increase the reliability and firmness of the contact between the spring sheet portion 122 and the first grounding terminal 110, thereby effectively improving the reliability and stability of the electrical connection between the first grounding terminal 110 and the second grounding terminal 120.

[0099] For example, see Figure 5 As shown, the angle between the spring piece portion 122 and the second thin sheet bending body 1242 can be α, and the value of α can be approximately 185°~189°, which can increase the elastic force during the contact process between the spring piece portion 122 and the first grounding terminal 110, help increase the reliability and firmness of the abutment between the spring piece portion 122 and the first grounding terminal 110, and improve the reliability and stability of the electrical connection between the first grounding terminal 110 and the second grounding terminal 120.

[0100] Correspondingly, when the first grounding terminal is provided with a spring sheet portion, the spring sheet portion and the first sheet bending body may also be arranged at an angle. The spring sheet portion may be offset in a direction close to the second grounding terminal. The angle between the spring sheet portion and the first sheet bending body may also be approximately 185° to 189°, which will not be described in detail here.

[0101] Figure 6 A schematic diagram of the structure of a second second grounding terminal provided in an embodiment of the present application.

[0102] See also Figure 6 As shown, in another possible implementation, the spring sheet portion 122 may include a connected spring sheet body 1221 and a spring sheet bending body 1222. The spring sheet body 1221 may be connected to the second thin sheet portion 124 through the spring sheet bending body 1222, and the spring sheet bending body 1222 may be arranged at an angle to the spring sheet body 1221 and the second thin sheet portion 124, respectively, so that the spring sheet body 1221 protrudes from the second thin sheet portion 124. The spring sheet body 1221 may abut against the first ground terminal 110.

[0103] Specifically, for example, in the process of forming the second grounding terminal 120, the spring portion 122 can be formed on the second grounding terminal 120 by a bending process. Through two bending actions, the spring bending body 1222 and the spring body 1221 are respectively formed. The spring bending body 1222 can make the spring body 1221 higher than the second thin sheet portion 124 in the first grounding terminal 110 and the second grounding terminal 120.

[0104] In this way, the distance between the spring body 1221 and the first ground terminal 110 can be closer, which can effectively increase the contact area between the spring body 1221 and the first ground terminal 110 and improve the reliability and stability of the contact between the spring body 1221 and the first ground terminal 110.

[0105] Correspondingly, when the first grounding terminal is provided with an elastic sheet portion, the elastic sheet body can be connected to the first thin sheet portion through an elastic sheet bending body, and the elastic sheet bending body can be arranged at an angle with the elastic sheet body and the first thin sheet portion, respectively, so that the elastic sheet body protrudes from the plane where the first thin sheet portion is located, and the elastic sheet body can abut against the second grounding terminal. No further details are given here.

[0106] Figure 7 A schematic diagram of the angle between a spring sheet body and a spring sheet bending body provided in an embodiment of the present application.

[0107] See also Figure 7 As shown, the angle between the spring body 1221 and the spring bending body 1222 can be β, and the value of β can be about 85° to 89°. The spring body can have a deflection angle in the direction toward the first ground terminal 110, which can increase the elastic force of the spring body 1221 in the contact process with the first ground terminal 110, help increase the reliability and firmness of the abutment between the spring body 1221 and the first ground terminal 110, improve the reliability and stability of the electrical connection between the first ground terminal 110 and the second ground terminal 120, and thus effectively improve the reliability and stability of signal return.

[0108] Figure 8 A schematic diagram of the structure of another connector provided in an embodiment of the present application, Fig. 9 A schematic diagram of the structure of a third second grounding terminal provided in an embodiment of the present application, Fig.10 A schematic diagram of the structure of the third second grounding terminal cooperating with the first grounding terminal provided in an embodiment of the present application.

[0109] For some possible implementations, see Figure 8 and Fig. 9As shown, the second thin sheet portion 124 may be provided with a second hollow portion 1243, and the second hollow portion 1243 may penetrate the second thin sheet portion 124 in the thickness direction of the second thin sheet portion 124. The shape of the elastic sheet portion 122 may be adapted to the shape of the second hollow portion 1243. One end of the elastic sheet portion 122 may abut against the first grounding terminal 110, and the other end of the elastic sheet portion 122 may be connected to the inner wall of one side of the second hollow portion 1243 close to the first grounding terminal 110. In the thickness direction of the second thin sheet portion 124, at least part of the elastic sheet portion 122 may overlap with the second thin sheet portion 124.

[0110] Specifically, for example, the elastic sheet portion 122 can be formed by folding part of the original second hollow portion 1243 outward. Fig.10 As shown, the shape of the elastic sheet portion 122 can be cut or trimmed on the second ground terminal 120 , and then the trimmed structure is folded outward to form the elastic sheet portion 122 .

[0111] After being folded, the spring piece portion 122 can abut against and connect with the first ground terminal 110, so that the second ground terminal 120 can be electrically connected to the first ground terminal 110 through the folded spring piece portion 122, thereby realizing a common ground connection of the two ground terminals.

[0112] In this way, the material of the second grounding terminal 120 itself can be used to form the spring portion 122, and there is no need to set additional material for forming the spring portion 122 outside the second grounding terminal 120. This can reduce the material used for the second grounding terminal 120 and reduce the material cost of the second grounding terminal 120.

[0113] Fig.11 A schematic structural diagram of a fourth second grounding terminal provided in an embodiment of the present application.

[0114] like Fig.10 As shown in , the spring piece portion 122 can be located above the second thin sheet portion 124 and the first ground terminal 110. For example, the spring piece portion 122 can be formed by folding a portion of the original second hollow portion 1243 counterclockwise (upward in the figure) to abut the spring piece portion 122 against the first ground terminal 110. Or, in another example, as Fig.11 As shown, the spring piece 122 can be located below the second thin sheet 124 and the first ground terminal 110. For example, the spring piece 122 can also be formed by folding part of the original second hollow portion 1243 clockwise (downward in the figure) to abut the spring piece 122 against the first ground terminal 110.

[0115] Continue to see Fig.11As shown, the second sheet portion 124 may further be provided with a second edge pressing body 1244 , and the second edge pressing body 1244 may be located at a side of the second hollow portion 1243 close to the first ground terminal 110 .

[0116] In some examples, the spring portion 122 abuts against the lower surface of the first ground terminal 110 . At this time, in the thickness direction of the second thin sheet portion 124 , the second edge pressing body 1244 and the first ground terminal 110 are located on the same side of the spring portion 122 .

[0117] In other examples, the spring sheet portion 122 abuts against the upper surface of the first grounding terminal 110. At this time, in the thickness direction of the second thin sheet portion 124, the second edge pressing body 1244 and the first grounding terminal 110 can be respectively located on the opposite sides of the spring sheet portion 122. For example, the spring sheet portion 122 can penetrate the gap between the first grounding terminal 110 and the second grounding terminal 120, and the end of the spring sheet portion 122 away from the second hollow portion 1243 is arranged on the upper surface of the first grounding terminal. The second edge pressing body 1244 can limit the spring sheet portion 122, and can press the spring sheet portion 122 in the direction close to the first grounding terminal 110 to limit the spring sheet portion 122 from moving in the direction away from the first grounding terminal 110. In this way, loosening or separation between the spring sheet portion 122 and the first grounding terminal 110 can be effectively reduced or avoided, and the reliability and stability of the abutment between the spring sheet portion 122 and the first grounding terminal 110 can be effectively improved.

[0118] Understandably, if Fig.10 In the case where the spring sheet portion 122 is located above the second thin sheet portion 124 and the first grounding terminal 110, in some examples, the spring sheet portion 122 abuts against the upper surface of the first grounding terminal 110. At this time, in the thickness direction of the second thin sheet portion 124, the second edge pressing body 1244 and the first grounding terminal 110 are located on the same side of the spring sheet portion 122. In other examples, the spring sheet portion 122 may abut against the lower surface of the first grounding terminal 110. At this time, in the thickness direction of the second thin sheet portion 124, the second edge pressing body 1244 and the first grounding terminal 110 may be located on opposite sides of the spring sheet portion 122, respectively. For example, the spring sheet portion 122 may penetrate the gap between the first grounding terminal 110 and the second grounding terminal 120, and one end of the spring sheet portion 122 away from the second hollow portion 1243 is arranged on the lower surface of the first grounding terminal.

[0119] The width of the second edge clamp 1244 may be d, and the value of d may be approximately 1 mm to 2 mm. This can increase the structural strength of the second edge clamp 1244, and enable the second edge clamp 1244 to provide a more stable clamping force for the spring piece 122, which can effectively reduce or avoid the second edge clamp 1244 from breaking and causing the film structure to fail, and help improve the structural stability of the second edge clamp 1244 and the spring piece 122.

[0120] Correspondingly, when the first grounding terminal 110 is provided with a spring sheet portion 122, a first hollow portion may be provided on the first thin sheet portion, and the first hollow portion penetrates the first thin sheet portion in the thickness direction of the first thin sheet portion. The shape of the spring sheet portion may be adapted to the shape of the first hollow portion. One end of the spring sheet portion may abut against the second grounding terminal, and the other end of the spring sheet portion may be connected to an inner wall of one side of the first hollow portion close to the second grounding terminal. In the thickness direction of the first thin sheet portion, at least part of the spring sheet portion overlaps with the first thin sheet portion.

[0121] The first sheet portion may be provided with a first edge pressing body, and the first edge pressing body may be located on a side of the first hollow portion close to the second grounding terminal, and in the thickness direction of the first sheet portion, the first edge pressing body and the second grounding terminal may be located on opposite sides of the spring sheet portion, respectively. Alternatively, in the thickness direction of the first sheet portion, the first edge pressing body and the second grounding terminal may be located on the same side of the spring sheet portion. The relative positional relationship between the first edge pressing body and the second grounding terminal can be referred to the previous description, and will not be repeated here.

[0122] In the embodiment of the present application, the number of the spring pieces 122 can be two, and the two spring pieces 122 can be arranged in parallel at intervals, and the first ground terminal 110 and the second ground terminal 120 can be electrically connected through the two spring pieces 122 to achieve a common ground connection. In this way, it is possible to avoid disconnection between the first ground terminal 110 and the second ground terminal 120 due to disconnection of one of the spring pieces 122, and the probability of disconnection between the first ground terminal 110 and the second ground terminal 120 can be reduced, which helps to increase the reliability and stability of the electrical connection between the first ground terminal 110 and the second ground terminal 120.

[0123] Alternatively, in some examples, there may be multiple spring pieces 122, and the multiple spring pieces 122 may be arranged in parallel and spaced apart on the second sheet portion 124. Specifically, the number of spring pieces 122 may be selected and set according to the specific application scenario and the size of the second sheet portion 124.

[0124] In the present application, the second ground terminal 120 may have a ground terminal 123. The length of the second ground terminal 120 may be greater than the length of the first ground terminal 110, and the width of the second ground terminal 120 may be greater than the width of the first ground terminal 110. During the signal return process, the signal on the first ground terminal 110 may flow to the second ground terminal 120 and return through the ground terminal 123 on the second ground terminal 120. In this way, the size of the signal return path can be effectively increased, and the efficiency of the signal return can be effectively improved.

[0125] Alternatively, the first ground terminal 110 has a ground terminal 123. The length of the first ground terminal 110 may be greater than the length of the second ground terminal 120, and the width of the first ground terminal 110 may be greater than the width of the second ground terminal 120. During the signal return process, the signal on the second ground terminal 120 may flow to the first ground terminal 110 and return through the ground terminal on the first ground terminal 110. The size of the signal return path can be effectively increased, and the efficiency of the signal return can be effectively improved.
