Copper Terminal Quality Appraisal
Nowadays, the copper terminal market is developing more and more rapidly, and there are more and more copper terminal manufacturers in the corresponding market. Copper terminals have become the most popular connector accessories. However, the quality of so many copper terminal products must be somewhat different. The difference is that there must be a significant gap between some good copper terminal products and inferior quality copper terminals. When you buy, you must also want to choose good copper terminals, but it is a more serious problem that you don’t know how to distinguish. , Now I will teach you a few basic methods of copper terminal quality appraisal, so that you can understand when you love to buy copper terminals. After appraising the quality of copper terminals, you can choose high-quality and suitable copper terminals.
The first is to make false sales for some irregular copper terminal manufacturers. The actual copper terminals sold by some copper terminal manufacturers are actually different from the copper terminals in the sample, which seriously affects the entire copper terminal market and uses some bad copper terminals. Deceptive sales, so here I teach you a way, when you go to buy copper terminals, you can bring a caliper, and take an overall measurement of the copper terminal that the copper terminal manufacturer wants to sell, including the thickness and size of the copper terminal. , The length is measured accurately, and then compare with the copper terminal of the same specification on the sample provided by the copper terminal manufacturer to confirm whether it is consistent. If there are obvious differences in size, it means that the copper terminal manufacturer is deceiving customers. , It must be an irregular copper terminal manufacturer and can cancel the transaction directly.
The second is to check the electroplating on the surface of the copper terminal. Generally, there are two types of electroplating methods for copper terminals, namely, tin and bright tin, because the electroplating method of tin and bright tin is much higher than that of bright tin, and there is a production cost. The difference is several times, so when we evaluate the quality of copper terminals, we must understand the difference between these two plating methods. Here, I will briefly tell you that tin tin is tin plating, and bright tin is copper tin plating. When you are appraising the quality of the copper terminal, confirm the plating method used for the copper terminal, and avoid some businesses that make false plating product marketing in order to increase profits, and make a slight modification on the outside, and use the copper terminal products in the form of bright tin. The sale of tin and tin production cost price.
Of course, we also need to check the insulating sleeve inside the copper terminal. This is a very important part of the quality evaluation of the copper terminal. The insulating sleeve will affect the use of the entire copper terminal. We can use tool pliers to test and confirm the copper The insulation sleeve inside the terminal is not damaged. If the internal copper terminal is cracked or white, this type of copper terminal is a product that is unqualified in terms of quality assessment.
Finally, the quality appraisal of the copper terminal is to identify and distinguish the material used for the copper terminal. Here, I will give you a popular science. The red copper is red and the brass is yellow. We can judge the use of this copper terminal product from the color. The material. In fact, both copper and brass are relatively good materials, but there are differences in performance, and there is not much difference in quality. What you really need to pay attention to is that some non-standard manufacturers use copper terminal products made of copper. This kind of copper The quality of the terminal is very inferior. The tension at the crimping part does not meet the standard at all, which will only cause a series of failures during use, which will cause problems in the entire connection. Therefore, you can properly increase the quality of the copper terminal. Some pressure, remove some copper terminals made of copper.
