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 socket, connector and electronic device. Background Technology

[0002] With the rapid development of electronic technology, especially communication technologies represented by 5G and 6G, electronic devices have become an indispensable part of people's lives. Connectors, as an essential component of electronic devices, also play a vital role in our lives. Connectors primarily ensure the smooth and continuous flow of current. A connector generally consists of a plug and a socket. The socket is typically soldered onto the electronic device, while the plug connects to other electronic components. The plug and socket work together to allow other electronic components to connect to the electronic device and perform a specific function. For example, multi-channel signal transmission devices, often used as connectors, are frequently employed in the circuit boards of mobile phones to transmit multiple wireless communication signals. The socket of the channel signal transmission device is mounted on the phone's circuit board, and the plug connects to the signal wire. When the plug and socket are connected, the communication signal in the signal wire is transmitted to the phone's circuit board. However, existing connectors still have several shortcomings, leading to unreliability and instability in their operation, all of which require further improvement. One issue is that existing connectors often use a pair of conductive contacts on one side of the plug and socket, which can easily reduce the reliability of the conductive connection, leading to current conduction failure. On the other hand, existing connectors lack a retaining structure to keep the sockets and plugs relatively fixed during mating, resulting in low connector reliability. During operation, the plugs and sockets are prone to relative movement or even detachment, causing unstable current conduction, especially for high-speed 5G and 6G signal transmissions where stable current is crucial, thus reducing high-speed transmission performance. Furthermore, the conductive contacts of existing connectors' sockets and plugs cannot provide sufficient elastic contact force to maintain a firm grip during mating, leading to unreliable and insufficient contact and unstable current conduction. Therefore, there is an urgent need for a socket, connector, and electronic device that ensures high reliability and stability during operation. Utility Model Content

[0028] In this embodiment, each socket signal terminal engages with the U-shaped groove structure via a snap-fit ​​on its snap-fit ​​portion. The interplay of recesses and protrusions ensures precise and stable terminal installation. The precise multi-snap-fit ​​and limiting structure work together to reduce the possibility of relative movement and accidental disengagement after the plug is inserted into the socket. This provides a solid mechanical guarantee for the connector's long-term stable operation in harsh environments (such as mobile devices and automotive equipment). The first movable groove 161, second movable groove 162, and third movable groove 163 on the protrusion 16 provide dedicated, undisturbed deformation space for the first elastic portion 31, second elastic portion 41, and third elastic portion of the first, second, and third signal terminals of the socket. When the plug is inserted, the elastic portion of the signal terminal can freely and smoothly deform within the corresponding movable groove, generating sufficient and consistent elastic resistance. This ensures that the conductive contacts between the socket and the plug maintain a tight and reliable electrical contact with low and stable contact resistance, which is particularly beneficial for low-loss, high-fidelity transmission of 5G / 6G high-frequency, high-speed signals. Each terminal is designed with clearly defined positioning and fixing features such as bayonets and recesses, corresponding one-to-one with the limiting grooves and protrusions on the insulator. This ensures accurate terminal placement, making it ideal for rapid and precise assembly using automated equipment, improving production efficiency and ensuring product consistency. This new socket, through its innovative dual-contact power terminals, flexible signal terminals with independent movement space, and multiple mechanical interlocking fixing structures, comprehensively addresses the shortcomings of existing connectors in terms of conductivity reliability, mechanical stability, and contact stability. Its beneficial effects directly address the high requirements of 5G / 6G high-speed transmission for connectors, significantly improving the performance of electronic devices during high-speed data communication and their long-term reliability. Example 2

[0029] This utility model provides a connector, including a socket as described above. The connector also includes a plug, which includes a plug insulator, a plug power terminal disposed on the plug insulator for cooperating with the socket power terminal 2, and a plug signal terminal for cooperating with a plurality of socket signal terminals. After the socket and the plug are plugged in, the socket power terminal and the plug power terminal are in contact with each other, and the socket signal terminal and the plug signal terminal are in contact with each other. The elastic part of the socket signal terminal undergoes elastic deformation, clamping the plug signal terminal at the contact position. The elastic deformation of the socket signal terminal ensures that the socket signal terminal and the plug signal terminal maintain effective contact at all times. Example 3
