Terminal machine for pressing made hard wires and strands of wire connection is also easy and convenient. According to the need, customer can choose to use finger to press the key or tool operation press the key.

Terminal quality depends on the following three factors: design, material selection and processing technology. Must pay attention to when choose terminal careful resolution: first is to look at the appearance: good product is like a handicraft look just give a person the feeling of comfort and pleasing to the eye; Second selection: better insulated parts with flame retardant engineering plastics, conductive materials, the use of copper can never use iron; Thread, is the most critical in the processing, if thread processing is not good, torsion moment does not amount to mark also loses the connection of wires.

Set up additional insulation and its test requirements higher than the basic insulation, is basic insulation is usually determined storefront fitment is not good enough, need additional insulation for final protection. And additional requirements below reinforced insulation, insulation because of additional insulation withstand direct impact, less than reinforced insulation. Terminal units in many cases, reinforced insulation equivalent to double insulation. Reinforced insulation does not completely equivalent to double insulation, its basic reason is the composition of reinforced insulation, are often a single layer of insulating system, insulation system analysis knows, insulation performance, and material density, thickness, weight, etc are all closely related to the insulation system on the probability of a hole, far more than two layers of insulation system through the hole in the stacked together to form a hole of probability.
