Description

Waterproof connector assembly

Technical Field

The utility model relates to the technology of connector field, in particular to a waterproof connector component.

Background Art

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.

When the male head in the existing connector assembly is connected to the female seat, not only is the connection between the male head and the female seat not sufficiently sealed and waterproof, and is easily affected by external water vapor during the connection process, but water vapor is also easily introduced into the connection between the internal terminal of the male head and the insulating part, as well as between the internal terminal of the female seat and the insulating part, thereby damaging the male head and the female seat and affecting the service life of the connector. At the same time, the sealing performance of the female seat when assembled with the external host is also insufficient, and is easily affected by external water vapor and dust during use; therefore, it is necessary to further improve the existing connector structure.
