What is the effect of oxidation of automobile terminal welding

Automotive terminal welding in the process of operation, always due to a variety of reasons and defects. Common defects include poor connector contact, short circuit between wires, open circuit, and bonding. So, what are the causes of the automotive terminal welding defects?

1, natural aging or damage

Harness use time exceeds the use period, the insulation layer of the harness begins to crack gradually, the mechanical strength begins to fall, and after a long time, it simply leads to short circuit, break, and other defects between the wire and the wire.

2, automobile terminal welding oxidation

When the wiring harness terminal is intact oxidized, it may have been deformed, it will also constitute poor wiring contact or short circuit, and then let the wiring harness defect.

3, electrical equipment defects

There is also a situation that is due to the overload of electrical equipment, short circuit, and then cause wiring harness defects.

4. Human reasons

One cause of the defects is improper human operation, such as unreasonable installation position of the wiring harness, incorrect wiring of the wiring harness and electrical equipment, and damage of the wiring harness components during maintenance.

Detection and identification of electronic wiring harness defects:

Taking iron: The rule of electronic wiring harness burning is that in the circuit of the power system, where the iron is taken, the electronic wiring harness is burned to where the junction of the burnt and missing part can be taken iron for the wire; If the electronic wiring harness burns out to the wiring part of an electrical equipment, it indicates that the electrical equipment is defective.

Short circuit: the electronic wiring harness is kneaded and impacted externally, resulting in damage to the insulation layer of the electronic wiring harness, resulting in a short circuit between the wires, making some electrical equipment out of control, and the safety wire is blown.

When judging, the electronic wiring harness connector at both ends of the electrical equipment and the control switch can be disassembled, and the short circuit of the line can be detected with an electric meter or a test light.
