In order to ensure the electrical contact and mechanical performance of the wire head and the electrical equipment meet the requirements, except for the single-strand copper core wire below 10mm2, the multi-strand copper wire below 2.5mm2 and the single-strand aluminum core wire can be directly connected with the electrical equipment, which is larger than the above For multi-strand or single-strand core wire of the specification, the terminal is usually soldered or crimped on the wire. This process is called wire end capping. However, in terms of process, the end caps of copper wires and aluminum wires are not completely identical. Copper wire capping methods are commonly used for soldering or crimping. 1, soldering method First remove the oxide layer and dirt on the surface of the wire head and the inner surface of the terminal hole, apply acid-free solder paste on the soldering surface, apply a layer of tin on the wire, and place the appropriate amount of solder into the wire hole of the terminal. Use a blowtorch to heat the terminal. When the solder melts, heat the tin wire into the terminal hole and continue heating until the solder completely penetrates into the core seam and fills the gap between the wire and the inner wall of the terminal hole. Stop heating. 2, crimping method Insert the cleaned and finished wire end directly into the cleaned terminal wire hole on the inner surface, and then crimp the wire end and the terminal block with crimping pliers according to the process requirements of the crimping pipe crimping method described earlier in this section. . Since the surface of the aluminum wire is extremely oxidizable, it is difficult to use the soldering method. They are usually capped by crimping. Before crimping, in addition to removing the oxide layer and dirt on the surface of the wire head and the inner surface of the wire terminal hole, the neutral Vaseline should be coated on the contact surfaces of the wire, and then the wire end is inserted into the terminal wire hole and pressed by crimping clamp.
