DJ90112-1.2 Automotive Waterproof Male Female Plug Seal Connector

3.1 Wire beam plug -in option selection improvement

The wire beam interpretation is the core component of the wire beam. The performance of the plug -in connection directly determines the overall performance of the wiring beam, and it plays a decisive role in the stability and safety of the electrical component of the vehicle. Plug -in waterproof plug -in, with waterproof sealing ring, and achieve waterproof levels of technical requirements. The interpretation is a secondary lock structure of the terminal, and the plastic shell secondary lock mechanism is used to ensure that the connection is firmly connected and the terminal has no return. After investigation, special car plugs are generally selected from Anpu and Dichth Waterproof Points.

3.2 Promotion of thread beam protection level

Research to meet the protection components and its installation process that meet the requirements of special automobile environment. The wiring beam is upgraded from the opening of the open tube to the closed -mouth ripple and the thermal contraction of the heating tube is used. In addition to the opening of the closed -mouth ripple, the overall is closed. Compared with the open -tuber tube, it is complicated to wear a sleeve.

After investigation and testing, the closed -mouth ripple pipe wearing a section of the branch line → wearing the main and branch line beam of the ripple tube → the ripple tube branch fixed circular process process. In order to improve the waterproofing performance of the wiring beam, the wire beam branch point is treated with tape fixation, thermal shrinkage, and silicon rubber irrigation and other techniques. The thermal shrinkage tube is selected from XX thermal tubes, and the silicon rubber is selected from XX silicon rubber. Both have passed tests such as high and low temperature, waterproof, salt and fog. When the branch point is fixed, the front end of the main trunk and the branch line is wrapped in the tape to be wrapped in the middle of the tape, and the full -wrapped method is used to wrap it to the line bracket branch point (the branch position requirements required by the drawing). Later, the tube of the tube of the tube of the tube in the middle of the set is at the mid -thermal reduction point, and the tape will not leak. Silicon rubber is seized at the gap between the wrapped tubes of the heat shrinkage tube, and the surface of the 24h is curing.
