Parallel plate screw-type terminals parallel plate screw-type terminal is the most widely used terminal, its process is simple, easy to process, the cost is very low. Plate and screw materials are generally made ??of A3 steel, galvanized surface after heat treatment, can achieve high strength and corrosion resistance. Usually the terminal conductive bar and plate will mold stamping some stripes or grid indentation, and tighten the screw, the stripes can damage the wire surface, increasing the contact area, so that the wire is not easy to emerge.
The greatest disadvantage of this wiring is difficult to compress the two wires of different diameters, the plate with the conductive strips always maintain a parallel relationship, and tighten the screw, plate lifting, two wires of different diameter can only be pressed line the larger diameter wire.The saddle-shaped screw-type terminal saddle-shaped screw-type terminals similar to the pillars terminal, but different processing methods and materials, cost between between pillars terminal plate terminal.
