4 pin 04R-TWPF-VSLE-S Waterproof Connector And Plug Plug-in For Automobiles

two-color wire
The cross-area of the wire is marked in front of the color code, and the unit is not marked when it is millimeter. For example, 1.25R means a red wire with a cross-sectional area of 1.25mm2; 1.0G-Y indicates a two-color wire with a cross-sectional area of 1.0mm2. The main color is green and the auxiliary color is yellow.
② High -voltage wire. The circuit between the car ignition coil and the spark plug uses a high -voltage ignition line, referred to as high -voltage lines. The core cross-sectional area of the car high-voltage wire is small (about 1.5mm2), the insulating package layer is thick, and the voltage resistance value is high. Generally, it should be above 15kV .
High-voltage line
③ Car wire beam. In order to make the entire car line regularly, convenient installation, and protect the insulation of the wires, except for high -voltage lines, batteries, and motivation cables on the car. Generally Wind bandaging beams, called wire beams, as shown in Figure 1-2-5.

(3) The function of the switching and switching device is to connect and cut off the connection circuit of the power supply and the power consumption equipment.
① ignition switch. The ignition switch is the most important switch in the automotive circuit, and is the control hub of the branch branches of each circuit. The ignition switch gear.
LOCK "gear: The entire vehicle circuit is disconnected, and all power equipment is not working. At the same time, the ignition key can only be inserted or pulled out in the" LOCK "gear.
"ACC" gear: Affiliated equipment power transmission. When the ignition key is rotated to the "ACC" gear, the electrical equipment circuit in the car is connected, and the radio, indoor lights and other electrical equipment can be used in the car. The air conditioner cannot be used.
"ON" gear: The entire vehicle circuit is connected to the gear. When the ignition key rotates to the "ON" gear, the electrical equipment circuits, ignition circuits, and light lighting device circuits in the car are connected. The ignition device of the engine is in a preheat state, and the engine is to be started.
"START" gear: The starting gear of the engine. When the ignition key rotates to the "START" gear, start the circuit to connect, the starter rotates, and drives the engine to rotate. After the engine starts, the ignition key should be released immediately to make the key automatically return to the "ON" gear to avoid damage to the starting motivation, and it is also conducive to the normal work of the engine.
② Combining switch. The combination switch (front light switch, light -changing switch), turning light switch, emergency alarm light switch, water scratch / cleaner switch, etc. are a multi -function switch, which is installed in a steering column that is convenient for drivers to control the driver.
