Description

Technical Field

[0001] The utility model belongs to the technical field related to connectors, and in particular relates to a waterproof structure of a connector. Background Art

[0002] The electrical connector is mainly used to ensure the smooth flow of current between the conductors and segments of the contact network. It is an important part of the main circuit of the contact network. In addition to meeting general performance requirements, the electrical connector must have good contact, reliable operation, and easy maintenance. Its reliability directly affects the normal operation of the aircraft circuit and involves the safety of the entire host. As the main electrical component, automotive electrical connectors are being widely used in automotive electronic equipment and systems. Electrical connectors are the basic components necessary to form a complete system in the electrical system. Waterproof performance is very important. The existing connector waterproof structure is mostly improved by setting a nut structure on the outside of one end of the connector. The threaded connection has a certain degree of waterproofness, but in special circumstances, when the connector is exposed to rain or immersed in water for a long time, water will penetrate into the connector through the gap of the threaded connection, which poses certain safety hazards.

[0003] In view of this, the present utility model is proposed. Utility Model Content
