The terminal material determines the insulation performance and electrical conductivity of the terminals. Each terminal determines the success of the project, any failure of the terminal will lead to the failure of the entire system engineering.With the continuous improvement of electronic technology, the terminal itself The structure and R & D technology has also been a generation of innovation, China's terminal industry also ushered in the pursuit of similar products in the development of a change in the process of technological substitution, and directly imitate the large terminal manufacturers of technology research and development results, Saving the product research and development funds in the field of industrial control, the terminal has become the most important parts products, as a connector, the terminal with its good connection performance quickly access to the field of industrial control welcome. Terminal is now widely Applied to various fields, including signal terminals, power terminals, connection terminals, etc., is the circuit in the connection side.
The crimp is a technique for compressing and displacing the metal within the specified limits and connecting the wires to the contact pair. A good crimp connection can produce a metal melt flow, making the wire and contact against the material Symmetrical deformation. This connection is similar to cold welding connections, can get better mechanical strength and electrical continuity, it can withstand even worse environmental conditions.It is generally believed that the use of the correct crimp connection better than tin, especially in High voltage applications must be crimped. Crimping should be used for special crimping pliers or automatic, semi-automatic crimping machine.
Terminals Positive pressure (marked as p) is the electrical equipment that is filled with pressurized air, inert gas or continuous access to clean air to prevent the explosive mixture from entering the enclosure. ), Refers to the electrical equipment that may cause the live parts of the spark, arc, or dangerous temperature to be immersed in the insulating oil so that it can not ignite the explosive mixture above the oil level. The sand type (marked q) means that the fine- The material is filled into the enclosure of the equipment so that the arc, flame propagation, shell wall temperature, or pellet surface temperature in the shell can not ignite the electrical equipment outside the enclosure.
