Description

Connector socket and plug

technical field

The utility model relates to the field of electronic equipment, in particular to a socket and a plug of a connector.

Background technique

With the continuous development of electronic equipment technology, the application of USB (Universal Serial Bus) is becoming more and more extensive. Especially in terminal devices such as smartphones and tablet computers, USB can be used for charging and data transmission. At present, the USB connectors on the market generally include sockets and plugs. The sockets are generally set on the terminal equipment, including the power terminals of the socket and the grounding terminals of the socket; the plugs are generally set on the data lines for electrical connection with external power sources, and The plug generally includes a power terminal of the plug and a ground terminal of the plug. When the socket is connected to the plug, the power terminal of the socket is connected to the power terminal of the plug, and the grounding terminal of the socket is connected to the grounding terminal of the plug to form a loop to realize charging of the terminal equipment by the external power supply.

However, since both the socket and the plug have only one power terminal and one ground terminal, on the one hand, the current resistance of the connector is limited, only about 1.8A, which is difficult to meet the charging needs of the terminal equipment; even if the power terminal and the ground terminal are replaced The high-quality material does not significantly improve the flow resistance of the connector, which reduces the user experience. On the other hand, if one of the above-mentioned four terminals constituting the loop fails, the loop will be disconnected, resulting in failure of the USB connector, reducing product reliability and user experience.

Utility model content
