When the terminal industry can emerge its own industry standards

Terminal shape looks simple, but the terminal must also undergo rigorous testing and product validation experiments cyclical production patterns. Which has a range of criteria.
Given the importance of the terminal, so the terminals in the design and use must comply with safety and environmental standards and only met the standards in order to buy the rest assured that with the peace of mind in order to avoid risks of accidents. General production terminals styling products manufacturers in the design execution is GB/T5095-1997 Electromechanical components for electronic equipment (basic testing procedures and measuring methods):. UL486E, UL1059 terminal product innovation in its field.
Currently, UL, IEC, CSA and DIN and other agencies in determining the terminal's power and performance specifications of the product, and there is no uniform standard. Users need to understand the difference between UL and IEC specifications.
Terminals manufactured in Europe using the IEC standard product specifications, products manufactured in the United States adopts UL standards. The difference between these two standards is very large. Engineers do not understand the determination of product specifications will take a considerable risk, because the choice of the terminal devices may not reach the required power level, or choose the specifications of the device far beyond the design needs.
In Europe, the current rating of the device is increased by monitoring the current temperature of the metal conductor determined. When the temperature of the metal pin is higher than ambient temperature of 45 ℃, staff will then measure the current as the rated current value (or the maximum current value) of the device. Another IEC specification allowing a current value, which is 80% of maximum current. Unlike this, UL Standard 90% 30 ℃ allow the temperature of the metal conductor current value higher than the ambient temperature of the device as the current nominal value.
Thus, the temperature of the metal conductor portion of all applications are very important factors. It is more important for industrial equipment. Since industrial equipment typically need to work at temperatures up to 80 ℃ environment. If the temperature of the terminals of the temperature be higher than 30 ℃ or 45 ℃, then the temperature of the terminals will exceed 100 ℃. The nominal value of the selected type and insulation materials used in the terminal device according to the product must be less than the rated current of the work, so as to ensure that they can reliably work within the desired temperature range. Sometimes, the device is suitable for compact packaging material may not be well positioned to meet the cooling requirements, so that the current use of these terminals when the device must be significantly lower than ratings.
