The structure of the connector: Waterproof connectors to achieve the effect of waterproof and dustproof. Generally can be divided into the overall seal and single-hole seal; the use of sealing material can be: rubber seal plug and plastic injection seal, the former is more common; with articulated body connector, the connector is more convenient to avoid With the locking mechanism of the connector, so that between the line or line and the electrical connection between the pieces more firmly to prevent loosening, generally used in the engine, the rain Scraping the motor and other bumpy vibration environment; with pressure wire cover connector, it can ensure that the connector inserted into the terminal tail crimp wire is not in the root of the connector when the unnecessary shaking, to reduce the vibration of the connector on the wire Of the shear force, improve the quality of the wiring harness;
The principle of selection of connectors
1 According to the electrical parts of the connector and its environment to choose a reasonable connector. For the engine compartment, the bottom of the chassis and other external contact with the outside world of the line and the line, or line with the electrical components docking connector, should choose the rubber seal plug with the connector, the best form of single-hole sealed to facilitate Easy maintenance of future disassembly;
2 according to the location of the connector and a reasonable way to choose a fixed connector structure. In the selection of the docking connector of the wiring harness and the wiring harness, it is better to select the connector with the hooking mechanism (attachment clip), and fix it to the sheet metal or the interior trim of the vehicle body nearby;
3 door harness and body wiring harness docking, the best choice with a locking mechanism of the connector to ensure that the door in the frequent opening and closing, to avoid the phenomenon of docking loosening; with gland body connectors are commonly used in vehicles Body vibration of the larger;
4 in the selection of the color of the connector, for the same type of connector, especially the docking connector and docking position are the same, should choose different colors of connectors to distinguish (Figure IV); In addition, based on the overall coordination of the appearance of the car, the engine compartment sheath preferred black or dark jacket;
5 from the engine closer to the connector should be selected high temperature nylon connector;
