They can be used in a variety of applications, such as computers, communication equipment, automobiles, industrial equipment, etc. The main function of connectors is to ensure the reliable transmission of signals or power while facilitating the connection and disconnection between devices.

[0003] However, the existing connector nut is designed with conventional threads inside. During the matching process with the connector body, there is a gap in the thread gap. Under long-term high temperature and high humidity conditions, water vapor is prone to intrusion, causing the metal parts inside the connector to rust, resulting in increased contact resistance of the connector, and prone to high-temperature deformation and burning of the connector. Utility Model Content

A connector shell 16 is provided at the outer side of the connector body 1. The connector shell 16 is made of plastic material.

[0032] In this embodiment, the specific implementation steps of a high-sealing, low-water-permeability connector are as follows: align the sealing sleeve 3 with the embedding groove 4 on the top of the connector body 5, nest the connection, ensure that the sealing sleeve is fully inserted to maintain good sealing, place the connector body 5 on the connector body 1, ensure the position is aligned, use the nut 8 to thread the connector body 5 to the connector body 1, ensure to tighten, but do not use too much force to avoid damaging the rubber ring 17 or the silicone seals 9 and 7, check the fixing bolts 14 on the side of the connector body 1, ensure that they are firmly fixed to improve the stability of the connection, connect the sealing fixing part 11 with the pin 12 on the side of the connector body 5, ensure that it can be rotatably connected, use the bayonet 15 to clamp the sealing fixing part 11 with the fixing part 10 to ensure that it is stable, and regularly check whether the connector is loose or worn during normal operation of the equipment.
