Copper Terminal Quality Identification

Nowadays, the Cable Lugs 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, but there are definitely differences in the quality of so many copper terminal products. There is definitely a clear gap between some good copper terminal products and poor quality copper terminals. When purchasing, everyone must want to choose good copper terminals, but not knowing how to distinguish is a more serious problem. Here I will teach you several basic methods of copper terminal quality identification, so that everyone can understand when they buy copper terminals by themselves, and after identifying the quality of copper terminals, choose high-quality and suitable copper terminals.

First of all, it is to target some irregular copper terminal manufacturers for false sales. The actual copper terminals sold by some copper terminal manufacturers are actually different from the copper terminals on the samples, which seriously affects the entire copper terminal market. Some bad copper terminals are used for deceptive sales. So here I will teach you a way. When you go to buy copper terminals, you can bring a caliper to measure the actual copper terminals to be sold by the copper terminal manufacturer. The thickness, size, and length of the copper terminals are measured accurately. Then compare them with the copper terminals of the same specifications on the samples provided by the copper terminal manufacturers to confirm whether they are consistent. If there are obvious differences in size, it means that this copper terminal manufacturer has deceived customers. It must be an irregular copper terminal manufacturer and the transaction can be canceled directly.

The second is to check the electroplating on the surface of the copper terminal. Generally, there are two electroplating methods for copper terminals: tantalum tin and bright tin. Because the tantalum tin electroplating method is much higher than the bright tin electroplating method, there is a difference in production cost. Therefore, when we conduct quality appraisal of copper terminals, we must make clear the difference between the two electroplating methods. Here I will briefly tell you that tantalum tin is tin plating, and bright tin is copper tin plating. When you conduct quality appraisal of copper terminals, confirm the electroplating method used for the copper terminal to avoid some merchants from making false electroplating product marketing in order to increase profits. Slightly modify the outside and sell the copper terminal products in the form of bright tin at the production cost price of tantalum tin.

Of course, we also need to check the insulation sleeve inside the copper terminal. This is a very important part of the quality appraisal of copper terminals. The insulation sleeve should affect the use of the entire copper terminal. We can use tool pliers to test and confirm that the insulation sleeve inside the copper terminal is not damaged. If the internal copper terminal has cracks or whitening, this type of copper terminal is a product that fails in quality appraisal.

Finally, the quality appraisal of copper terminals is to identify and distinguish the materials used for copper terminals. Here is some popular science for everyone. Copper is red and brass is yellow. We can judge the material used for this copper terminal product by the color. In fact, copper and brass are both relatively good materials, but they are different in performance, and there is not much difference in quality. What we really need to pay attention to is that some non-standard manufacturers use copper terminals made of raw copper. This kind of copper terminal is of very poor quality. The tension of the wire pressing part does not meet the standard at all, which will only cause a series of faults during use, thereby causing problems in the entire connection. Therefore, when appraising the quality of copper terminals, you can add some pressure appropriately to exclude some copper terminals made of raw copper.
