How to identify the quality of the terminal block

How to distinguish the quality of the terminal block and the strength of the terminal manufacturer?

First, look at their terminal insulation information:

Insulation material is very important for the safety of the switch socket, but it is difficult for the average consumer to discriminate. It is of course the best to do the incineration test on the core part when purchasing. If there is no condition, the appearance is poor. It is very light in the hand, there is no feeling after pressing, and it is easy to have scratches. Good materials are generally strong in texture, difficult to scratch, and have a tight structure and a heavy weight after molding. Good resin data, with flame retardant, arc resistant, heat resistant and sturdy features.

Second, look at the copper of the terminal block, although it can not be seen clearly when purchasing, but it is very important for the socket. The easiest way to distinguish is to use a plug to try to test the strength of the insertion is not moderate, and then rub it by hand, the socket is really a bit heavy. Can test with a magnet, is it ferroalloy or iron steel plated copper.

To choose an excellent terminal, you must first consider the power handling factor. Buyers cannot simply read the data sheet and cannot ensure accurate comparison data. It is also necessary to understand how the commodity function data listed in the manual is tested and determined.

Third, when you do not have the above experience, it is more guaranteed to choose a brand or a terminal product with a brand company.
