Every step of terminal wire manufacturing is very important, which will directly or indirectly affect the actual effect of the application, and it is widely used in electronic products. If there is no wire harness, it cannot be used in practice. The wire harness can be said to be a whole, which is the same as our human heart, but the terminal wire is also very important in the actual use process. If it is not used correctly, it is also It will affect the actual use effect of the product, just like a blood vessel on the heart.
1. Selection of raw materials: The quality of raw materials is directly related to the life of the terminal wire. Normally, the cable of the terminal wire is made of pure copper, but not all wire harness processing manufacturers will follow this industry rule. Some wire harness manufacturers In order to reduce costs and earn more profits, copper-clad steel, iron-clad or copper-clad zinc cables are used to make terminal wires. The quality of the wire harness made of this material can be imagined, not to mention the longevity. Counted.
2. Selection of standards: Different thickness wire harnesses can withstand different currents. If thin wire harnesses are used under too high current, the wire harness will heat up because it cannot withstand the large current, and then cause the wire harness or facilities to burn out. Seriously, it may even cause a fire. Therefore, when using the wiring harness, it must be checked whether it can withstand the corresponding current.
3. Application environment: The application environment of the terminal wire is also a key factor affecting the life of the wire harness. The terminal wire used outdoors is definitely not as long as the indoor service life. Like the terminal wire used in outdoor advertising light boxes, it is exposed to the sun for a long time , Rain will greatly prolong the service life of the terminal line.
Therefore, when selecting terminal wires, it is necessary to comprehensively consider various factors and select suitable terminal wires, not just considering the cost part at the moment. The following issues should be paid attention to when inspecting the terminal line during actual production:
2. Check whether there are scratches, grains, variegated colors, dirt, etc. on the surface of the extruded wire body.
4. The surface of the wire should be clean, and there should be no dirt, scratches, scratches or damage on the outside of the inner core wire.
5. When punching terminals, there should be no defects such as deep punching, shallow punching, broken copper wires, or broken wires.
6. If the wire rack is injection-molded, it is necessary to check whether there are defects such as shrinkage, draping, lack of glue, and deformation.
7. Whether the terminal wire penetrates into the plastic shell, the color of the wire, and the sequence of the wire are reversed or not in place.
In fact, there are many brands of terminal wires, with different types, prices, and sizes. If the product you choose has been used for a long time and is durable enough, it should be classified as a high-quality product.
