How To Distinguish The Quality Of The Terminal

The terminal block is an accessory product used to complete the electrical connection, which is divided into the category of the connector in the industry. With the increasing level of industrial automation and stricter and more accurate industrial control requirements, the amount of wiring terminals has gradually increased. With the development of the electronics industry, the scope of application of terminal blocks is increasing, and there are more and more varieties.

1. It can be judged from the price that his price is lower than all prices in the market, so it goes without saying.

2. Look at the copper material of the terminal. Although it is not clear when you buy it, it is very important for the socket. The simple way to judge is to use the plug to try whether the plugging force is moderate, and then use your hand to check whether the socket is really heavy. Can use a magnet to test whether it is ferroalloy or iron-steel plated with copper.

3. It depends on their terminal insulation materials:

Of course, it is best to do a extinguishing test on the central components when purchasing. If there is no condition, it is a poor material in terms of appearance. It is very light to hold in the hand, there is no feeling after pressing, and it is easy to scratch. Good materials generally have a harder texture, are difficult to scratch, have a compact structure after molding, and are heavier. A good resin material has the characteristics of flame-retardant, arc-resistant, heat-resistant and hard.
