Resolve on terminal block rated voltage, rated current

With the innovative connection technology, more and more connectivity products are widely used in research and development by one, the common terminal on the market today have a rail terminal blocks, PCB terminal blocks, spring-type terminals, and so on.
For terminal block itself, rated current, rated voltage of two cognitive attributes is essential, there are two attributes do the music for this specific analysis: Rated voltage, also known as operating voltage, it mainly depends on the insulating material used in the machine even , the  WISDOM printer usb cable spacing between the size of the contact pair. Some components or devices at less than its rated voltage, may not fulfill its proper function. Rated voltage terminals should be understood as a matter of fact manufacturer recommended maximum operating voltage. In principle, the terminal row below the rated voltage can work. I tend According terminals withstand voltage (dielectric strength) indicators, in accordance with the use of the environment, the security level required for the rational use of the rated voltage. In other words, the same pressure indicators, depending on the use of environmental and safety requirements, can be used to different maximum operating voltage. It is also more in line with the objective usage.
Rated current, also known as the operating current. terminal block with the same rated voltage, lower than the rated current WISDOM displayport cable  situation, terminals generally work well. In the terminal design process, is through terminals designed to meet the thermal requirements of the rated current, because the contact to have the current flows due to the presence of conductor resistance and contact resistance, exposure to heat will. When it exceeds a certain limit heat will destroy the insulation and terminals form contact softening of the surface coating, resulting in failure. Therefore, to limit the rated current, in fact, want to limit the terminal block inside  WISDOM barrier terminal block temperature does not exceed the design value. In the choice of when to pay attention to the question is: for multi-core terminals, the rated current must be derated. This should cause a large current situations in importance, such as φ3.5mm exposure to the general provisions of the rated current of 50A, but in five core derated to 33% of the time used for each core is only rated current 38A, Number of cores The more, the greater derating.
