Electricians need to deal with all kinds of circuit lines during their work, and generally use pliers tools. Electrician pliers are special pliers for electricians. The utility model is characterized in that the clamp handle is provided with an insulating sleeve which can bear high pressure. There are many kinds of electrician tongs, and the commonly used ones are:

1, wire pliers

Wire cutters are widely used in electrical engineering. Jaws can be used to bend or clamp wire ends, teeth can be used to tighten or loosen nuts, knife edges can be used to cut wires or clamp wire insulation layers, and side openings can be used to cut hard wires such as wire cores and steel wires.

Before using the wire cutters, check whether the insulation of the wire cutters is good, so as to avoid electric shock accidents during live working. When cutting wires with electricity, two kinds of wires with different potentials (such as phase line and zero line, phase line and phase line, etc.). ) Do not use a knife edge to cut at the same time, so as to avoid short circuit accidents.

2, needle-nosed pliers

Needle-nosed pliers, named after their tapering heads, are suitable for narrow working spaces. Needle-nosed pliers can be used to cut smaller wires; Can be used to clamp smaller screws, nuts, washers, wires, etc. It can also be used to form a single wire (such as straight line, bending, etc.). ). If the needle-nosed pliers are used for live working, check whether the insulation is good, and the metal part should not touch the human body or the adjacent live body during operation.

3. diagonal pliers

Dedicated to cutting all kinds of wires and cables. For materials with different thickness and hardness, diagonal pliers with appropriate size should be selected.

4. Stripping pliers

Wire stripper is a special tool for stripping the insulation of thin wires. When stripping the wire insulation, the wire stripper first determines the insulation length to be stripped with a ruler, then puts the wire into the corresponding cutting edge (slightly larger than the wire diameter), and then holds the clamp handle by hand to strip the insulation of the wire.

5, wire pressing pliers

Crimping pliers are mainly used to process cables and connectors in electrical operations. According to the size of the crimping connector, the built-in crimping holes are also different. Among them, the wire pressing pliers are specially used for the processing of network cable crystal heads and telephone line crystal heads.

Second, the electrician pliers are generally used in what operating occasions?

Electrician is a special type of work, which needs to work in a charged environment, so it is dangerous, and the insulation and safety requirements of the electrician pliers used are also very high, and the use occasions are also limited. Under what circumstances are electrician tongs generally used?

Usually, electrician tongs are mostly used in wire and circuit maintenance, electrical instrument installation, cable and connector processing and other fields. , usually used for cutting cables and stripping cable insulation. Because most of these occasions have relatively narrow operating space, electrician pliers are generally small in size and suitable for use in places with narrow space, especially needle-nosed pliers. Electricians can choose suitable pliers according to the needs of working conditions in actual operation.

Three, electrician pliers use matters needing attention

1, the insulation sheath of the wire clamp is generally 500V V V. Check whether the insulation performance of the handle is good when using it. If the insulation is damaged, an electric shock accident will occur during live working.

2. When working live, the distance between the hand and the metal part should be not less than 2cm to ensure personal safety.

3. When cutting live wires, it is forbidden to cut the phase line and neutral line at the same time with a knife edge, or cut two phase lines at the same time to avoid short circuit accidents.

4. Be sure to oil the clamping shaft to prevent rust.

5. When the insulated handle is damaged, it cannot be used to cut live wires.

6. The tong head is tapered and heat-treated, so the clamped object should not be too big or too hard to prevent the tong head from being damaged.

7, stripping pliers can't be used as wire cutters, so as not to damage the incision.

8. The selected incision diameter must be larger than the core diameter, that is, the wire must be cut and stripped on the incision larger than the core diameter, and the large-diameter wire cannot be stripped with a small incision to avoid cutting the core wire.

9, when live working, first check whether the handle insulation is good, in order to prevent electric shock.
