WISDOM terminal block is a little drawback

"Interrupted multiple lines using Terminal" (especially touched electrical power, the current is large, the impact of heat on the line terminals working properly) need to pay attention, and the presence of risk.
Its long-term risks, terminal block is not short-term. Because of the time, on screw terminals will corrode, subject to thermal expansion and contraction, will naturally loose, copper oxide, and so some of WISDOM fiber optic connectors  the reasons, resulting in poor contact heat, and accidents.
Buildings should now minimize the use of terminals, whenever possible puncture clamp. Screw terminal called the Dragon three rotating terminal! Originated in the United States! After the production of imitation Taiwan! There are currently only in the production of Taiwan's Golden Pen!
Wire terminals for easy connection and it WISDOM rca cable  is generally used to connect the point source line clockwise twist in a very simple, terminal block is going to take a few shares of wires into the appropriate types of terminals connected together and tighten the wires wiring applications, it is actually some sealed inside an insulating plastic sheet metal, wire can be inserted into the hole at each end, for tightening or loosening screws, such as two wires, and sometimes need to be connected, and sometimes WISDOM scart splitter  need to disconnect, Then you can use the terminal to connect them, and can be disconnected at any time without having to weld them together or intertwined, it is convenient
