On terminals selection
2017-11-02
Selection of terminals, is nothing more than the diameter, current wiring direction, applications, wiring diameter and current, do not say here, that is, the size of the wire diameter and rated current. Wiring direction generally positive wiring and side outlet is easy to operate for the convenience of the technical staff to improve work efficiency applications, this is a very frequently asked questions, a wide range of terminals applications, for example, you buy the wiring the terminal is soldered on the PCB board, then you can not go to the rail above the terminals wiring, general butt, vacant, fixed Universal.
Generally fixed terminal before you have to understand what you want the terminal, the terminal functional classification, ordinary terminal, insurance terminal, test terminal and ground terminal, double terminals, double conduction terminal, three-terminal, layer conduction terminal, an inlet and double outlet terminal into a three terminal double inlet and outlet terminals knife terminal overvoltage protection terminals, marked terminal. Current classification is divided into ordinary terminal the (small current terminal), the large current terminals (100A 25MM line above). Classified according to the appearance. Can be divided into the rail terminal JH1, JH2, JH5, JH9, JHY1 fixed terminals (such as TB, TC, X3, X5, H Series, JQH8-12-12B JQH8 JQH8-12C) PCB terminal (PCB terminals).
Terminals characterization: that each connection area by insulating base, U-shaped frame, nut, hex screws and upper and lower living blocks on the next live with wiring hole between the relative contact surface, SHCS through the nut top in the upper Activity block, its purpose is to the different thickness of the cable is directly connected on the high current terminal.
Compared with the prior art, it is flexible combination the stitching terminal unit number, crimp or stranded cable connections are secure and reliable, simple and convenient installation and maintenance, etc..
