Copper screw type terminal connection mode is more traditional, advantages of this connection is the largest more convenient and reliable. Because the pillars of large volume, heat itself is very good. High current switch, socket will produce high temperature, so generally use copper terminals to achieve cooling, temperature rise test requirements. The screw creates a great pressure that causes a slight deformation of the wire and firmly presses the wire to make it difficult to disengage. But the drawback is that the wire screw can be easily crushed or broken, the relative cost of other screw type terminal contact resistance and high copper rivet joints can produce higher copper, copper pillars may be relatively rotated by tightening screws, causing serious consequences.
