The Biggest 23 Common Adverse Conditions Of Terminal Crimping Mistakes You Can Easily Avoid-4
15. The contact area of the terminal is too large, resulting in uneven contact surface and difficult to disassemble
If the contact area of the terminal is too large, the contact surface may be uneven, which makes it difficult to disassemble. Here are some possible solutions:
Use the right tools: Using the right tools can help you remove the terminals more easily, such as using the right sized wrench or screwdriver.
Proper use of force: Proper force can help you remove the terminal more easily. However, using too much force may damage the terminals or other components.
Checking the connector: Checking the connector for damage or dirt may also be a solution. If the connector has damage or dirt, it may affect the contact area and make it difficult to remove. In this case, you need to clean the connector or replace the connector.
Use lubricants: Using lubricants can help reduce the problem of excessive contact area. Lubricants reduce friction and make disassembly easier.
Seek professional help: If you are not sure how to remove the terminal, or if you find that the terminal is damaged after removal, it is best to seek professional help. This ensures that you remove the terminals correctly and replace damaged parts if needed.
16. The terminal is in poor contact with the cable
The following problems may occur in the circuit if there is poor contact between the terminal and the cable:
Increased resistance: Poor contact increases the resistance of the circuit, resulting in reduced current, and affects the normal operation of the circuit.
Heat: Because the current cannot flow smoothly through the poorly contacted part, it will generate local heat, which may damage the insulation layer of the wire or cause a fire.
Signal interference: Poor contact may also lead to poor signal transmission, affecting the stability and performance of the device. In order to avoid poor contact between terminals and cable wires, pay attention to the following points:
Clean: Keep the surface of terminals and cable wires clean to avoid interference from surface dirt and oxides.
Fastening: Ensure that the connection between the terminal and the cable is tight to avoid loosening.
Protection: Use insulating materials or sheathing to protect the cable wire to avoid damage to the wire caused by the external environment.
Choose the right wiring method: Choose the right wiring method according to the specific situation to ensure good contact.
17. There is too much gap between the terminal and the cable rod, which affects the contact quality
Too much clearance between the terminal and the cable will affect the contact quality.
The quality of the contact between the cable and the terminal is very important for the reliability and stability of the circuit. When there is too much gap between the terminal and the cable, the contact resistance will increase, which will affect the normal operation of the circuit. This can cause current instability, voltage drop, heat and other problems, and may even damage electronic devices.
In order to avoid this situation, it should be ensured that the gap between the terminal and the cable wire is as small as possible to ensure good contact quality. In addition, attention should also be paid to the use of good quality cable wires and terminals, to avoid the use of aging, worn or damaged wires and terminals, to ensure the reliability and safety of the circuit.
18. There is air or foreign matter in the terminal, which affects the electrical connection
If there is air or foreign matter inside the terminal, it may affect the stability and reliability of the electrical connection. This is because air or foreign bodies may cause problems such as increased contact resistance, reduced contact area or poor contact, which affects the flow of current and signal transmission. In addition, air or foreign matter may also cause arc, spark, short circuit and other faults, affecting the normal operation of electrical equipment and even damaging the equipment.
Therefore, when installing and maintaining electrical equipment, you should pay attention to check whether there is air or foreign matter inside the terminal, and remove it in time. If you find that there is a problem inside the terminal, you can take appropriate cleaning, polishing, coating protective layer and other methods to solve. In addition, when selecting and using connectors and terminals, it should also consider their dustproof, waterproof, corrosion resistance and other characteristics to ensure its long-term stable operation.
