How To Quickly Determine The Quality Of Cold-pressed Terminal Blocks In A Market Rife With Counterfeit And Substandard Products?

There are many types of crimp contacts on the market, and many of them are of poor quality. So how can we judge the quality of the terminals we choose?

1. You can judge by price. If the price is lower than all other prices on the market, then it's safe to say it's good.

2. Check the copper material at the end of the crimp contact pin. Although you can't see it clearly when buying, it's crucial for the socket. The simplest way to judge is to test the insertion and removal force with a plug to see if it's appropriate, and then lift the socket in your hand to see if it's noticeably heavy. You can also use a magnet to test if it's made of iron alloy or copper-plated iron steel.

3. Check the insulation material of the crimp contact female:

The insulation material is very important for the safety of switches and sockets, but it's difficult for ordinary consumers to judge. Ideally, you should perform a combustion test on the core components before purchasing. If that's not possible, from an appearance perspective, inferior materials feel very light in your hand, lack a sense of weight, and are easily scratched. Good materials are generally hard, difficult to scratch, have a dense structure after molding, and are relatively heavy. Good resin materials are flame-retardant, arc-resistant, heat-resistant, and hard.

4. If you lack the above experience, you can also choose cold-pressed end products from branded or reputable companies.
