The choice of insulated terminals depends mainly on the insulation materials of their terminals. Insulation is very important for the safety of the terminals. However, it is difficult for ordinary consumers to judge. If you can do a combustion test on the core components of the terminal, it is good. If there is no condition, in terms of appearance, good materials are generally hard and hard to scratch, and the structure is tight and the weight is heavy after molding. Good resin material, flame retardant, arc resistant, heat resistant and hard.

Terminal blocks are one of the most common copper tubes and are one of the most common non-ferrous metals. The demand for such copper pipes is relatively large, and the copper pipes are relatively light in weight, which can help people to alleviate the troubles that may be caused during transportation. Better, generally can be applied to heat exchange equipment. When people choose the terminal block, the copper material of the terminal block is not obvious when purchased, but it is very important for the socket. The easiest way to judge is to use a plug to try out whether the insertion force is moderate, and then rub it with your hand, whether the socket is really a bit heavy.

To choose a quality terminal, you must first consider the power handling factor. Buyers cannot simply read the data sheet and cannot guarantee the correct comparison data. It is also necessary to know how the product function data listed in the manual is tested and determined.
