3. Cold pressure

When the cold pressure is connected, first select the correct wire for the cold -pressure wiring terminal, peel off the wire insulating layer of the wire, so that the length of the naked wire is equal to the length of the metal cylinder on the wiring terminal. If the peeling wire is matched with the part of the tube metal, there is no space, indicating that the size of the cold pressure wiring terminal is appropriate, as shown in Figure 1-40 (a); if the wire does not match the cylinder, or too loose, then Explain the selected wire or wiring terminal size error. Insert the wire until the insulating layer on the wire is exposed to the end of the metal cylinder, as shown in Figure 1-40 (b). Then put the wires and terminals into a threading pliers. The color of the terminal insulation layer should match the color on the pressure connection tool. Place horizontally, and the tube is facing up. Then, the pierced tie mouth is vertically on the terminal and placed on the cylinder, and the lower pressure thread is placed. After the pressure is completed, the finished product is shown in Figure 1-40 (C). Try to pull the wires and terminals, the successful cold pressure wiring terminals are not easy to be pulled open.

pressure connecting cold pressure wiring terminals

Single -stock wires and cold -pressure wiring terminal pressure will generate weaknesses on the wires. Because the wires are inconsistent with the terminal, the possibility of loosening the connection connection is more likely. If a solid -core wire must be used, welded after light pressure connection.

4. Common error thread

Several common error lines are shown in Figure 1-41. Figure 1-41 (A) The specifications of the cold-voltage wiring terminal in the medium-cold pressure wiring terminal are too small, so that the wires cannot be completely plugged into the cold-voltage wiring terminal; The wires should not exceed the requirements of the outer body of the cylinder, and it is recommended to trim the guide wire; Figure 1-41 (C) The insulation part of the wiring terminals corresponding to is too much, which is easy to cause hidden safety hazards.

Automotive circuit is a comprehensive comprehensive integration of power system, starting system, ignition system, lighting system, lighting and signal system, and auxiliary electrical appliances. Sex network. The vehicle circuit is the same as the general circuit. It is also composed of power supply, load (electric equipment), wires, switches, protection devices, etc., but they all have their own characteristics and laws.

By learning the classification and characteristics of auto circuits, the classification and characteristics of the switch, wires, and protection devices in the automotive circuit by learning the relevant content of automotive wires, car wire beams, car control switches, circuit protection devices, circuit protection devices, and relay.
