At present, there are many manufacturers in the insulated terminals industry, which there are good, of course, there are some poor-quality products. How to choose some terminal blocks is very important. Insulated terminals in addition to considering the business license, price, site visits, also from the product's appearance, material, torque these three aspects to consider. We'll talk about it in detail below.
Here is the content:
l From the appearance
l From the material side
l Torque
l Terminal type
Most of the production of insulated terminals today for sampling electrical testing, and good terminal blocks should have good workmanship, that is, the surface is smooth, no scratches, no burrs at the corners, and wall thickness uniform. More importantly, the plug and pin seat fit high, no plugging force is too high and too low phenomenon. The easy way is to start from the outside. This is not to say that if the appearance is fine then the insulated terminals are probably fine, but if the appearance is too different, then the terminal already knows that it is defective without examining its interior.
Generally speaking, the material of insulated terminals can be divided into two major parts: one is the plastic parts, to have a good flame retardant, that is, UL94V-0 flame retardant grade; here is a relatively simple test method is to ignite with an open flame, if the plastic parts leave the open flame extinguished, it means that the terminal has a very good flame retardant performance;
The second is the crimp frame, many customers often say that the insulated terminals are copper material or not, and here is the crimp frame. Generally speaking, the copper frame than iron ore has a more angular texture. To ensure the quality of the problem, you can take apart the plastic parts to remove the crimp frame for further testing, but also cannot listen to the sales side of the story.
Nowadays, in some of the insulated terminals on the market, the reason for poor contact is the screw torque cannot meet the requirements, so the screw torque of the terminal blocks is particularly important. It affects the connection and torsion of insulated terminals so it is best to test it personally.
In the current market, the insulated terminals can be divided into European terminal block series, plug-in terminal block series, transformer terminal block, spring-type terminal block series, rail terminal block series, etc. Different types of terminals perform different functions. We can select the right terminal block according to the required function.
CHS has been awarded as a "Zhejiang export famous brand", and passed OHSAS18001 certification, upgraded to "Changhong Plastic Group". The industry standard drafted by our group has passed the expert review and other honors. Our philosophy is to survive by quality and develop by reputation. We carefully examine every insulated terminal before it leaves the factory, from the interior details to the exterior surfaces. We will not let substandard products appear on the market.
