Electronic power industry to resolve the technical requirements for the terminal
Published：2014-01-10 09:03:11 Views：
In the power electronics industry, the implementation of the 3C certification standards required for use of the terminal set higher standards for the industry commonly used plug-in terminals , terminal and rail fence terminals , Elinker Electric through the compilation of relevant information , the new technical requirements to share with you :
( A ) The plug -in terminal requirements : for a smooth insertion force , the contact resistance can occur after a certain number of difficulties plug or plugged increases and so on, on this point is the power system relay protection specifically requested it, so on the tablet to have a certain conductivity and elastic modulus and tensile strength, corrosion resistance and strong metal surfaces , insulation materials are flame-retardant and insulation levels are higher, and there is : the amount of current , screw torque, anti-vibration , pitch tolerances, appearance and other aspects ;
(B ) on the barrier type terminal requirements : good appearance , safety performance is mainly: creepage distances and clearances must meet the standards of protection of electrical equipment , anti -corrosive screws to be better. Carrying parts clamp temperature can not exceed 45K, the median length of the terminal can not have warpage, choose a large current terminal shell structure of the insulation thickness requirements and materials ;
(C ) for the rail terminal requirements : better housing strength , resistance property must meet UL94 V-0, hard cards or cards can not appear when the product is not installed on the upper rail phenomenon, high pressure line screw torque requirements , have a good appearance phenomenon stitching multi-chip set , electrical parameters and identification of the terminal must be clear mission and accurate. Protection against electric shock and creepage distances and clearances between the terminal and the terminal , and the terminal and other conductive parts must meet the relevant standards.
Elinker Electric Terminal is a professional research and development , production and sales in one of the service providers, the company has skilled and industry experienced R & D and engineering teams , Elinker Electric has been advocating the " revitalization of the national brand," the core values, by continuing to create value for customers to walk the road of prosperity of local enterprises . The terminal is firmly standard technical requirements , and resolutely not back feed production , strongly reducing the rate of returned products , our production terminals are widely used in electric power, transportation , electronics, machinery and other industries.
