Description

Technical Field

[0001] The utility model relates to the technology of connector field, in particular to a welding wire type connector component. 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 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] In order to simplify the assembly process, the existing connectors choose to assemble the terminals and the insulating parts together by plugging them together. However, this assembly method not only makes the sealing performance of the plug-in connection between the terminal and the insulating part poor, resulting in poor waterproof performance, but also the front-to-back holding force between the male terminal and the insulating part is insufficient after the male connector is assembled, which makes it easy for the PIN to be withdrawn. At the same time, the air tightness between the male connector and the female connector is also insufficient when connected, and it is easy to be disturbed by external water vapor during the connection process, thereby affecting the connection process. Therefore, it is necessary to make further improvements to the existing connector structure. Utility Model Content
