The wire stripper is one of the common tools used by electricians for circuit maintenance, etc., and is used to allow the electrician to strip the insulation layer on the surface of the wire head. The wire stripper can separate the insulation of the cut wire from the wire, and can also prevent electric shock. And usually, when many people use wire strippers for wire processing, they do not know how to use wire strippers. Let me introduce you to the use of wire strippers.
Performance standards of wire stripping pliers: the pliers head can be opened and closed flexibly, and can be opened and closed freely under the action of a spring; when the cutting edge is closed, the gap between the cutting edges is not more than 0.3mm; HRA56 or no less than HRC30; the wire stripper can smoothly strip the plastic or rubber insulation layer on the outside of the core; the handle of the wire stripper has sufficient bending strength, and the adjustable end surface wire stripper after 20N · m load test , The permanent deformation of the clamp handle is not more than 1mm.

　 How to use wire strippers
Â
The main points of using wire stripper: According to the diameter of the wire, the diameter of the blade of the wire stripper should be selected.
1. According to the thickness of the cable, select the corresponding stripping blade
2. Place the prepared cable in the middle of the blade of the stripping tool and choose the length of the stripped cable
3. Hold the handle of the stripping tool, clamp the cable, and slowly force the outer skin of the cable to slowly peel off
4. Loosen the handle of the tool and take out the cable. At this time, the cable metal is neatly exposed, and the remaining insulating plastics are intact.

　　 Structure principle of wire stripper
Â
When gripping the handle of the wire stripper to make it work, the spring in the wire stripper is first compressed, so that the tightening mechanism tightens the wire. At this time, the shear mechanism will not move due to the torsion spring 1. When the tightening mechanism completely clamps the electric wire, the force received by the torsion spring 1 gradually changes to roughly deform the torsion spring 1, so that the shearing mechanism starts to work. At this time, the force received by the torsion spring 2 is not enough to separate the clamping mechanism from the shearing mechanism. After the shearing mechanism completely cuts the wire sheath, the shearing mechanism is clamped. At this time, the force applied by the torsion spring 2 increases. When the force applied by the torsion spring 2 reaches a certain level, the torsion spring 2 begins to deform, and the clamping mechanism is separated from the shearing mechanism, so that the insulation of the wire is cut off , So as to achieve the purpose of stripping.

Precautions for using wire strippers
Â
Pay attention to the following three safety precautions when using wire strippers daily:
1. Please wear goggles when operating;
2. In order not to hurt people and objects around the fragment, please confirm the direction of the fragment splash before cutting off;
3. Be sure to close the tip of the blade tightly and place it in a safe place where children cannot reach.
The above is the content about the use method of wire stripping pliers introduced to you. Wire stripping pliers are also a relatively professional electrician tool, so we must understand its use method in order to use it in normal use. Operation without damaging the wires or stripping pliers.
