Description

Technical Field

[0001] The utility model relates to the technology of connector field, in particular to a connector component capable of passing large current. Background Art

[0002] Connectors are also called connectors. In China, they are also called joints and sockets, and generally refer to electrical connectors. That is, a device that connects two active devices to transmit current or signals. The male end and the female end can transmit information or current after contact, and are also called connectors. The basic performance of connectors can be divided into three categories: mechanical performance, electrical performance, and environmental performance. Another important mechanical performance is the mechanical life of the connector. Mechanical life is actually a durability indicator, which is called mechanical operation in the national standard GB5095. It is based on one insertion and one removal as a cycle, and whether the connector can normally complete its connection function (such as contact resistance value) after the specified insertion and removal cycle is used as the basis for judgment.

[0003] The connector includes a signal terminal for transmitting signals and a power terminal for transmitting current. The signal terminal and the power terminal in the existing connector terminal group have the same structure, and the conductivity of the power terminal is related to the size of the power terminal. Therefore, the power terminal in the existing connector cannot bear large currents due to its small size; therefore, its use is limited; it cannot be used in scenarios where large currents are required to pass through. At the same time, the power terminal of a small size is prone to overheating during long-term use, thereby affecting the transmission process of the connector. Therefore, it is necessary to make further improvements to the existing connector structure. Utility Model Content
