The crimping method is a wiring method that presses copper wires together through pressure.

The operation steps are as follows:

1. Use insulation stripping pliers to strip the insulation layer of the wire;
2. Insert the terminal copper and aluminum, and insert the wire into the terminal copper and aluminum;
3. Place the wire shrink sleeve at the connection between the wire and the copper and aluminum terminal to ensure that the connection has good insulation properties;
4. Use crimping pliers to press the copper and aluminum terminals tightly to ensure a firm and reliable connection;
5. Finally, check whether the connection is firm and whether there is any short circuit, leakage, etc.

Precautions:
1. Before connecting the wires, turn off the power supply;
2. Before connecting the copper and aluminum terminals, you need to ensure that there is no voltage in the wire;
3. When connecting wires, pay attention to whether the specifications of the wires match the specifications of the copper and aluminum terminals;
4. When connecting wires, pay attention to the insulation performance of the connection and whether there is leakage, etc.;
5. When using tools, pay attention to safety and do not use damaged or invalid tools.

In short, to correctly connect copper and aluminum terminals, you need to select the appropriate terminals, prepare the corresponding tools, follow the correct steps to connect, and pay attention to some details that need to be paid attention to in the connection, so as to ensure that the connection is firm and reliable and achieve the expected results.
