Description

Technical Field

[0001] This utility model belongs to the field of 5G and 6G high-speed signal transmission technology, and particularly relates to a plug, connector and electronic device. Background Technology

[0002] With the rapid development of electronic technology, society has gradually entered the 5G and 6G era. 5G and 6G signals have higher requirements for transmission speeds, demanding faster transmission rates. Connectors, as indispensable components in electronic devices, play a crucial role in the high-speed transmission of 5G and 6G signals. Existing 5G and 6G high-speed transmission connectors generally consist of a socket and a plug. The socket is soldered to the circuit board of an electronic device, such as a mobile phone, via socket solder pads. The plug is soldered to a circuit board containing signal processing components, such as a plug circuit board. After the plug and socket are connected, the communication signal processed by the signal processing component is transmitted sequentially through the plug and socket to the mobile phone's circuit board. The stability and secure connection of the plug to the socket significantly impacts the connector's operational stability and the quality of high-speed 5G and 6G signal transmission. However, in existing technologies, when plugging and socket are connected and fixed together, only an interference fit is generally used, lacking a corresponding locking and fixing structure. This results in unreliable connections, causing the plug and socket to wobble or even detach during operation. Consequently, the plug cannot maintain a secure connection with the socket, making it impossible for the plug to stably transmit signals between the plug and socket. This decrease in signal transmission capability leads to poor high-speed transmission performance of 5G and 6G signals. Utility Model Content

[0041] Example 1

[0042] See Figures 1-9This utility model provides a plug including a plug insulator 1, a plug power terminal 2, and a plug signal terminal 3. Both the plug power terminal 2 and the plug signal terminal 3 are made of metal. A cavity 15 is formed on one end face of the plug insulator 1.

The second protrusion 1131 and the second recess 251 cooperate to fix the plug power terminal 2; a plug signal terminal 3 is provided on the plug signal terminal mounting part 12, and the plug signal terminal 3 is provided with a third recess 361 that cooperates with the third protrusion 121. The plug signal terminal 3 is fixed by the cooperation of the third protrusion 121 and the third recess 361.

[0043] The plug power terminal mounting portion 11 includes a side concave surface 111 provided along the end face of the plug insulator 1 along its length, an upper concave surface 112 formed on the upper end face of the plug insulator 1, and a mounting groove 113 at one end away from the side concave surface 111. The mounting groove 113 communicates with the upper concave surface 112 on the side wall of the plug insulator 1 along its width. The first protrusion 1111 is located at the intersection of the side concave surface 111 and the upper concave surface 112, and the first protrusion 1111 extends along the side wall of the plug insulator 1 along its width. The insulator 1 protrudes along its length, that is, it protrudes towards the end away from the cavity 15. A first positioning protrusion 13 is provided between the upper concave surface 112 and the mounting groove 113, and a second positioning protrusion 14 is provided between the mounting groove 113 and the plug signal terminal mounting part 12. The first positioning protrusion 13 and the second positioning protrusion 14 are formed by the plug power terminal mounting part 11 and the plug signal terminal mounting part 12 recessed on the plug insulator 1, which is used to achieve the positioning function of the plug power terminal 2 and the plug signal terminal 3.

[0044] A third positioning protrusion 17 is provided at the four corners of the plug insulator 1. A limiting member 16 is also symmetrically provided at the bottom of both ends of the plug insulator 1 in the width direction. The limiting member 16 is integrally formed with the plug insulator 1. A first limiting groove 161 is symmetrically opened at both ends of the bottom of each limiting member 16 along its length direction. A second limiting groove 163 and a third limiting groove 164 are provided at the bottom of each limiting member 16 between the two symmetrically arranged first limiting grooves 161, and the second limiting groove 163 and the third limiting groove 164 are connected.

[0045] The plug power terminal 2 includes an integrally formed connecting part 21, a connecting part 22, and a connecting part 23. The connecting part 23 is provided in pairs on both ends of the connecting part 21 along its length. The connecting part 22 is connected to the connecting part 21 and the connecting part 23 on the upper end face of the connecting part 21 and the connecting part 23. A first notch 231 is also provided on the connecting part 22 and the connecting part 23. The first notch 231 is provided in pairs along the length of the plug power terminal 2. A second notch 212 is provided at the position where the connecting part 21 and the connecting part 23 are connected.

[0046] In this embodiment, a first contact portion 211 is provided at the connection position between the connecting part 21 and the connecting part 22, and a second contact portion 232 is provided at the connection position between the connecting part 22 and the connecting part 3. The second contact portion 232 is located at the end of the first notch 231 away from the connecting part 21. Both the first contact portion 211 and the second contact portion 232 have an outwardly convex arc surface structure. The first recess 213 is provided on the inner side of the arc surface structure of the first contact portion 211, and the second recess 251 is provided on the inner side of the arc surface structure of the second contact portion 232. The second contact portion 232 is located at the end of the connecting part 22 away from the connecting part 21. A first extension 233 is provided at the position of the connecting part 21. The first extension 233 is parallel to the connecting part 23. The connecting part 22, the connecting part 23 and the first extension 233 are connected to each other to form a first U-shaped groove 25. The second recess 251 is located in the first U-shaped groove 25 at a position corresponding to the second contact part 232. A plug power terminal welding part 24 is provided at the end of the connecting part 23 away from the connecting part 22. The plug power terminal welding parts 24 are symmetrically arranged on the two connecting parts 23. Each plug power terminal welding part 24 has a limit opening 241.

[0047] When the plug power terminal 2 is located on the plug power terminal mounting part 11, by placing the connecting part 21 on the side concave surface 111, and the connecting part 22 on the upper concave surface 112 and abutting against the contact surface 221, the first U-shaped groove 25 is placed in the mounting groove 13, the first recess 213 is placed on the first protrusion 1111, and the second recess 251 is placed on the second protrusion 1131, the cooperation between the first recess 213 and the first protrusion 1111 and the cooperation between the second recess 251 and the second protrusion 1131 achieves the connection between the plug and socket during insertion and removal. To ensure stability in the insertion and removal direction and prevent the plug power terminal 2 from loosening during long-term use, the first extension 233 is placed on the mounting groove 113 within the cavity 15. The first positioning protrusion 13 engages with the first notch 231, and the second notch 212 engages with the third positioning protrusion 17, thus positioning the plug power terminal 2 on the plug insulator 1 along its length and width directions, improving connection stability. The plug power terminal welding part 24 is placed within the first limiting groove 161, achieving positioning of the plug power terminal 2 in the height direction of the plug insulator 1. A third extension 162 is also provided at the position where the plug insulator 1 mates with the limiting opening 241. The third extension 162 mates with the limiting opening to position the plug power terminal welding part 24, preventing loosening of the welding due to frequent insertion and removal between the plug and socket during long-term use, and improving product lifespan.

[0048] The plug signal terminal mounting part 12 has an inverted U-shaped groove structure. The third protrusion 121 is placed on the inverted U-shaped groove of the plug signal terminal mounting part 12. The position and direction of the third protrusion 121 are consistent with the position and direction of the second protrusion 1131.

[0049] The plug signal terminal 3 includes a second extension 31, a connecting four-part 32, and a connecting five-part 33. The second extension 31 and the connecting five-part 33 are arranged parallel to each other. One end of the connecting four-part 32 is connected to the top of the second extension 31, and the other end is connected to the top of the connecting five-part 33. The second extension 31, the connecting four-part 32, and the connecting five-part 33 form a second U-shaped groove 36. A third contact part 311 is provided on the outer wall where the second extension 31 and the connecting four-part 32 connect. The third contact part 311 has an outwardly convex arc surface structure, and the third recess 3... 61 is located on the inner side of the arc surface structure of the third contact portion 311. The plug signal terminal is also provided with a connecting sixth portion 34 at the end of the connecting fifth portion 33 away from the connecting fourth portion 32. The plug signal terminal welding portion 35 is provided at the end of the connecting sixth portion 34 away from the connecting fifth portion 33. The width of the plug signal terminal welding portion 35, the second extension portion 31, the connecting fourth portion 32, the connecting fifth portion 33 and the connecting sixth portion 34 are the same. The width of the plug signal terminal welding portion 35 is smaller than the width of its connecting sixth portion 34, so that the arc surface of the third contact portion 311 has a sufficiently large contact surface, improving the stability of the connection.

[0050] When the plug signal terminal 3 is disposed on the plug signal terminal mounting part 12, the second U-shaped groove 36 is placed in the inverted U-shaped groove of the plug signal terminal mounting part 12 to fix the plug signal terminal 3 in the length and width directions of the plug insulator 1. The third protrusion 121 is connected with the third recess 361 to achieve stability in the insertion and removal direction during the plug and socket insertion and removal process, ensuring that the plug signal terminal 3 will not loosen during long-term use. The plug signal terminal welding part 35 is placed in the second limiting groove 163 and the third limiting groove 164 to fix the plug signal terminal 3 along the height direction of the plug insulator 1, so that the plug signal terminal 3 can be stably connected to the plug insulator 1. Both the power terminal soldering part 24 and the signal terminal soldering part 35 of the plug are soldered onto the plug circuit board. The power terminal mounting part 11 of the plug adopts a design that combines a side concave surface 111, an upper concave surface 112, and a mounting groove 113. The mounting groove 113 matches the structure of the first U-shaped groove 25 of the power terminal 2 of the plug. The signal terminal mounting part 12 of the plug adopts an inverted U-shaped groove that mates with the second U-shaped groove 36. This modular design makes the installation of the terminals more convenient. Quick positioning and fixing can be achieved through the interlocking of the protrusions and recesses, reducing assembly complexity and improving production efficiency.

[0051] In this embodiment, a mechanical interlocking structure is formed by providing a first protrusion 1111, a second protrusion 1131, and a third arc-shaped protrusion 121 on the plug insulator, which cooperate with the first recess 213 and the second recess 251 of the plug power terminal 2 and the third recess 361 of the plug signal terminal 3. This design effectively avoids the instability caused by interference fit alone, making the plug and socket more firmly fixed after insertion, preventing relative shaking or detachment during operation, thereby improving the overall reliability of the connector; the precise positioning and fixing of the plug power terminal and plug signal terminal ensure the stability of the plug-socket contact point. This reduces impedance changes and signal loss during signal transmission, and is particularly suitable for high-speed signal transmission scenarios such as 5G and 6G, helping to maintain high-quality signal transmission and avoiding signal attenuation or interruption due to loose connection.

[0052] Example 2

[0053] This utility model provides a connector, including a plug as described above. The connector also includes a socket, which includes a socket insulator, a socket power terminal disposed on the socket insulator for cooperating with the plug power terminal 2, and a socket signal terminal for cooperating with the plug signal terminal 3. After the plug and socket are inserted and engaged, the plug power terminal 2 and the socket power terminal are in contact with each other, and the socket power terminal undergoes elastic deformation at the contact portion. The plug signal terminal 3 and the socket signal terminal are in contact with each other, and the socket signal terminal undergoes elastic deformation at the contact portion. The elastic deformation of the socket power terminal and the socket signal terminal ensures that the socket power terminal and the plug power terminal 2, as well as the plug signal terminal 3 and the socket signal terminal, can maintain effective contact at all times.

[0054] Example 3

[0055] This invention provides an electronic device, including the plug and connector as described above. It has the same beneficial effects as the plug or connector described above, and will not be repeated here.

[0056] Example 4

[0057] like Figure 10-11As shown, this embodiment is an improvement on the structure of the plug power terminal 2 based on the above embodiment 1. In this embodiment, a first recess 214 is provided on the connecting part 21. The first connecting part 241 and the second connecting part 22 are connected by an arc part 215. The first connecting part and the third connecting part are connected by an arc part 216. The second connecting part 22 and the third connecting part 23 are connected by an arc part 217. The second connecting part 22 and the first extension part 233 are connected by an arc part 218. The arc part 215, the arc part 216 and the arc part 217 are connected by an arc part 218. All three parts 217 are formed by stretching, while the four arc-shaped parts 218 are formed by bending. The stretching and bending processes allow the power terminals to be integrally formed, effectively improving their strength and ensuring efficient signal transmission. A first recess 214 is provided on the end face of the connecting part 21, and a second recess 234 is provided on the end face of the connecting part 23. The first recess 214 and the second recess 215 engage with the contact portion of the socket power terminal to prevent loosening and ensure electrical connection between the socket power terminal and the plug power terminal. To prevent deformation after the mounting groove 113 mates with the first U-shaped groove 25, which could lead to loosening between the plug power terminal 2 and the plug insulator 1, a connecting arm 26 is provided between the two opposing first extensions 233 in this embodiment. The connecting arm 26 connects to the first extension 233 at the end furthest from the arc-shaped parts 218, thus preventing deformation after the mounting groove 113 mates with the first U-shaped groove 25 and ensuring reliable connection of the plug power terminal.

[0058] Example 5

[0059] like Figure 12-13 As shown, this embodiment is an improvement on the structure of the plug power terminal 2 based on the above embodiment 1. The plug power terminal 2 in this embodiment also includes a fourth extension 27, which is arranged parallel to the connecting part 22 and located near the cavity 15. The fourth extension 27 is connected to the connecting part 21. The fourth extension 27 also has a pair of small solder feet 271 at both ends along its length direction, and the length direction of the small solder feet 271 is consistent with the length direction of the plug insulator 1. The length direction of the plug power terminal welding part 24 is consistent with the width direction of the plug insulator 1. The plug power terminal welding part 24 and the small solder feet 271 are both welded to the connected circuit board, which improves the gripping force between the plug power terminal 2 and the circuit board at the welding point, making the connection of the plug power terminal 2 more firm and ensuring the stability of signal transmission.

[0060] Example 6

[0061] like Figure 14-15As shown, this embodiment is an improvement on the structure of the plug power terminal 2 based on the above embodiment 5. In this embodiment, the length direction of the small solder 271 is the same as the length direction of the power terminal solder part 24, and both are arranged along the width direction of the plug insulator 1. The width of the small solder 271 is the same as the width of the power terminal solder part 24. There is a gap between the small solder 271 and the power terminal solder part 24. Compared with the embodiment 1 which only has one power terminal solder part 24, the plug power terminal 2 in this embodiment has more positions to be soldered to the circuit board, which can effectively improve the stability of the connection.

[0062] Example 7

[0063] This embodiment is an improvement on the structure of the plug power terminal 2 based on the above embodiment 1. In this embodiment, the plug power terminal is formed by cutting the plug signal terminal 2 along the length direction of the plug insulator 1 from the middle as in embodiment 1. The plug power terminals 2 are arranged in pairs at one end of the plug insulator 1 along the length direction. With this design, only half of the mold is needed in actual production. The mold can be symmetrically set up at the top and bottom for processing and production, which can greatly reduce the production difficulty and improve the production efficiency.

[0064] The above description is merely a specific implementation of this application. Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the specific working processes of the systems, modules, and units described above can be referred to the corresponding processes in the foregoing method embodiments, and will not be repeated here. It should be understood that the protection scope of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the protection scope of this application.
