Description

Technical Field

[0001] The utility model relates to the technology of connector field, in particular to a welding wire type connector female seat. 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 processing process, the existing connector female socket adopts the plug-in installation method to install the female socket terminal. However, this installation method will make the sealing of the connection between the female socket terminal and the insulating part poor. During use, water is easy to enter the inside of the connector female socket from the connection and damage the connector female socket, thereby affecting the service life of the connector female socket. The waterproof performance is poor, and water will also enter the connection between the connector female socket and the external installation part and the connection with the male head during use, thereby affecting the stability of the connection process between the female socket and the male head. Therefore, it is necessary to make further improvements to the existing connector female socket structure. Utility Model Content
