DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0021] Please refer to Figure 1-Figure 7 The present invention proposes a high-speed connector, comprising a shell 1 and at least one group of connecting components 2; the connecting components 2 are respectively arranged in the shell 1; each connecting component 2 comprises a main body 3, a grounding device 4 and a plurality of terminals 5, and the terminals 5 are arranged and distributed on the main body 3; the grounding device 4 is fixed on the main body 3 and contacts the terminals 5; the grounding device 4 is provided with a plurality of contact portions 401, and the contact portions 401 are respectively in contact with the terminals 5; each terminal comprises a plurality of supporting portions 501 and non-supporting portions 502, and the supporting portions 501 and the non-supporting portions 502 are alternately arranged; each supporting portion 501 is provided with at least one material-digging area 503 for increasing the holding force; the main body 3 is provided with a plurality of placement positions 301 corresponding to the supporting portions 501, and the supporting portions 501 are respectively located in the placement positions 301.

[0022] In this embodiment, a plurality of connection components 2 are provided in the housing 1 for transmitting current or signals. Figure 2As shown, each connection assembly 2 includes a main body 3, a grounding device 4 and a plurality of terminals 5, and the terminals 5 are arranged and distributed on the main body 3. The grounding device 4 and the main body 3 are integrally formed by injection molding, so that the grounding device 4 can be fixed on the terminal 5. Specifically, as Figure 3 As shown, the grounding device 4 is provided with a plurality of contact portions 401, which can contact the terminal 5 in the form of elastic contacts instead of laser welding. The grounding device 4 is integrally formed with the main body, which can improve the reliability and stability between the terminal 5 and the grounding device 4. At the same time, a stable connection between the terminal 5 and the grounding device 4 can be achieved without laser welding equipment, which greatly reduces the production cost. In the actual production of the product, the difficulty of the production process is also reduced.

[0023] like Figure 4 and Figure 5 As shown, the terminal 5 includes a plurality of supporting portions 501 and a plurality of non-supporting portions 502. The portion of the terminal 5 located inside the main body 3 is defined as the supporting portion 501 and is used to provide support. The portion of the terminal 5 located outside the main body 3 is defined as the non-supporting portion 502. The supporting portion 501 and the non-supporting portion 502 are arranged alternately, and both ends of the supporting portion 501 are connected to the non-supporting portion 502.

[0024] Each support portion 501 is provided with a hollowing area 503 for increasing the holding force of the terminal 5. The hollowing area 503 is an area for hollowing the terminal 5. Figure 6 As shown, during the production process, the terminals 5 in area B are connected, and the bridge in the middle needs to be cut by a jig. During the cutting process, when the holding force of the terminals 5 in the main body 3 is low, gaps are easily generated during the process and the terminals 5 are separated from the plastic main body 3. However, the present application provides a material removal area 503 at the support portion 501, and the terminals 5 are removed at the material removal area 503, which can improve the holding force of the terminals 5.

[0025] like Figure 7 As shown, the main body 3 is provided with a placement position 301 corresponding to the support portion 501 , and the support portion 501 can be respectively arranged in the placement position 301 , thereby supporting the terminal 5 .

[0026] Please refer to Figure 2 and Figure 3 The grounding device 4 includes a grounding plate 402, which is arranged on the main body 3 and fixedly connected to the main body 3; the grounding plate 402 is fixedly connected to the contact portion 401, and the contact portion 401 is arranged and distributed on the grounding plate 402; a connecting portion 403 is provided between the grounding plate 402 and the contact portion 401, and the connecting portion 403 is curved, and the grounding plate 402 is protruded on the terminal 5; the main body 3 is provided with a heat dissipation portion 308, and the heat dissipation portion 308 is connected to the grounding plate 402.

[0027] In a specific implementation, the contact parts 401 are arranged on the grounding sheet 402, and the contact parts 401 are in contact with the terminals 5 respectively, and are fixed on the terminals 5 instead of laser welding. Figure 2 As shown, the grounding sheet 402 is in sheet shape and is arranged parallel to the terminal 5 and is used for grounding. The connecting portion 403 is arranged between the grounding sheet 402 and the contact portion 401 and is integrally formed with the grounding sheet 402 and the contact portion 401. The grounding sheet 402 is protrudingly arranged on the terminal 5 to improve the problem of crosstalk between the terminals 5.

[0028] Furthermore, the grounding plate 402 may be made of a flexible metal material, such as copper alloy or silver-plated copper, to improve the durability and reliability of the grounding plate 402 and reduce contact resistance during high-frequency signal transmission.

[0029] like Figure 2 As shown, further, the main body 3 is provided with a heat dissipation portion 308, and the heat dissipation portion 308 is connected to the grounding plate 402. The heat dissipation portion 308 is integrally formed with the main body 3, and the heat dissipation portion 308 can be made of copper or aluminum alloy and has thermal conductivity. During the process of data transmission of the connector, the heat of the grounding plate 402 can be conducted, thereby playing a role in heat dissipation.

[0030] Please refer to Figure 8 The contact portions 401 are respectively provided with contact surfaces 404 , and the contact surfaces 404 are respectively in contact with the surfaces of the terminals 5 .

[0031] In specific implementation: the contact surface 404 contacts the surface of the terminal 5, so that the terminal 5 can be grounded through the grounding device 4. Through the surface-to-surface contact, a larger contact area can be provided to ensure the stability of the connection between the terminal 5 and the grounding device 4.

[0032] Please refer to Figure 5 , the width of the supporting portion 501 is smaller than the width of the non-supporting portion 502 .

[0033] In specific implementation: the support portion 501 has a hollowed-out area 503 , so its width is smaller than that of the non-support portion 502 . The hollowed-out area 503 enables the terminal 5 to remain original when cutting the bridge, and avoids separation from the main body 3 .

[0034] Please refer to Figure 5-Figure 10The placement positions 301 are respectively provided with through grooves 302, and the shape of the through grooves 302 corresponds to the support portion 501; the support portions 501 are respectively located in the through grooves 302 and are tightly fitted with the groove walls of the through grooves 302; the through grooves 302 include a first portion 303, a second portion 304 and a third portion 305, and the first portion 303 and the third portion 305 are respectively arranged on both sides of the second portion 304, and the widths of the first portion 303 and the third portion 305 are greater than the width of the second portion 304; the groove walls of the through grooves 302 are provided with a buffer layer for providing a buffering force, and the buffer layer abuts against the support portion 501.

[0035] In specific implementation: each placement position 301 is respectively provided with a through groove 302. During assembly, the terminal 5 will be placed in the through groove 302, and the size and shape of the through groove 302 correspond to the support portion 501, so that the support portion 501 can fit tightly with the groove wall of the through groove 302 to avoid the generation of gaps that cause the terminal 5 to loosen.

[0036] For details, please refer to Fig.10 The through groove 302 includes a first portion 303, a second portion 304 and a third portion 305. The first portion 303 and the third portion 305 are respectively arranged on both sides of the second portion 304. The width of the first portion 303 and the third portion 305 is greater than the width of the second portion 304, forming a shape that is narrow in the middle and wide on both sides. When the non-support portion 502 is subjected to an external force, the middle area of ​​the supporting portion 501 is narrow, so that elastic deformation can be generated, and the original state can be restored after the external force is released, and it is not easy to generate an active gap between the main body 3.

[0037] Furthermore, a buffer layer is provided on the groove wall of the through groove 302, and the buffer layer is provided between the support portion 501 of the terminal 5 and the through groove 302. When the support portion 501 of the terminal 5 contacts the body 3, the buffer layer can provide a buffer force to prevent the terminal 5 from loosening, thereby increasing the stability of the terminal 5.

[0038] Please refer to the attached Fig.11 The present application also includes a first installation group 6 and a second installation group 7. The first installation group 6 and the second installation group 7 are arranged opposite to each other and are respectively engaged with the main body 3.
