Terminal blocks connection technique characteristics and shortcomings.

Wire nut

Backward technology, due to external pressure for metal flat on wires to connect, it is easy to loose falls off, metal for iron or aluminum, poor corrosion resistance, conductivity difference; shell as a normal plastic, flame resistance difference, not resistant to high temperatures; for multiple line is basically nothing, not; needed tools, easily damaged during operation shell; low efficiency.

Common screw terminal blocks

Structure simple, ends using screws tight solid wire, is easy loose off, metal more for iron or brass, resistance corrosion sexual difference, conductive sexual difference; shell for General plastic, flame retardant sexual difference, does not resistance high temperature, cannot full insulated, easy contact to internal metal; for more unit line, screws is easy agent injury or pressure broken part wire; connector part metal more bare; is difficult to long road branch; efficiency low.

Black tape

Trouble connection technology, life expectancy short, easy to aging, loss, poor flame retardant, look ugly, not resistant to high temperature, low efficiency.

In order to eliminate the hidden circuit fault, in order to facilitate the detection of failures in the future, for appearance of wiring convenience, more power to you and your family safe, recommended be sure to use the excellent decoration supporting quality--the electric circuit PCB wiring terminals.
