Analysis of advantages and disadvantages of the thread-free wiring terminal
Screwless terminals are widely used in lighting system kb0, instrumentation, communications equipment, power and other industrial products, but in the production of large power and low voltage electrical appliances, full consideration should be given to the voltage difference brought about a series of problems, it should be used with caution the thread-free wiring terminal.
As everyone knows in numerous terminals, no thread wiring terminal is more mature and widely application of the quick wiring terminal. But in the control and protection switch, socket in the national standard, is only suitable for the rated current of10 ~16 A products, the current products, not suitable for the use of the thread-free wiring terminal.
Although the thread-free wiring terminal does not apply to the current environment, but its most obvious advantage is connection speed, as long as the wire is inserted into the mounting holes can be, so that we can save the time of screw, when in installation is very convenient; can realize positive wiring, wire and a screwdriver can be from the same direction parallel to terminal, so that wiring assembly personnel can obtain a docking line optimal visibility.
Shanghai people intelligent electric said the thread-free wiring terminal is also very obvious shortcomings, remove the lead is not convenient for wire, strict, elastic pressing is not reliable. But in need of some emergency installation, fast and without screw terminal is really a good choice.
