Environmental requirements for wiring terminals
Insulating components should use flame-retardant engineering plastics, and conductive materials that should use copper should never use iron; The plastic insulation material and conductive components of terminal blocks are directly related to the quality of the terminals, and they respectively determine the insulation and conductive functions of the terminal blocks. The failure of any wiring terminal will lead to the failure of the entire system engineering. The most crucial aspect is the processing of wiring terminal threads. If the thread processing is not good and the torque does not meet the standard, the function of connecting the wires will be lost. Thread refers to the thread used for connecting the wiring terminals on the instrument to the field connector, such as the thread specifications commonly used for fixing the connection cable joints in some two wire transmitters in the industry.
Modern terminal design, material selection, and processing technology are the three core factors that affect the quality of terminal blocks, while accurately handling the design of terminal blocks
Material selection and processing technology are also prerequisites for various terminal manufacturers to win the market.
With the increasing demand for environmental protection, it is necessary to meet the environmental requirements of terminal blocks. Terminal blocks must comply with relevant safety and environmental standards when designed and used. Only by meeting the standards can one buy with peace of mind, use with peace of mind, and avoid potential safety hazards. Manufacturers of general wiring terminals follow GB/T5095-1997 for mechanical and electrical components used in electronic equipment (basic test procedures and measurement methods) when designing standardized products: UL486E, UL1059. At the same time, the addition of halogen-free flame retardants, non-toxic conductor insulators, and lead-free coatings are all positive responses to this requirement.
A good wiring terminal product is like a handicraft that gives people a refreshing and pleasing feeling; Many terminal companies believe that it plays an important role in product appearance and user friendliness. Terminal blocks must be easy to install on site, as they are often installed at the front end of easily visible product panels, so marketing personnel often have a certain say in the appearance of terminal block products.
