The role of crimping pliers

The role of crimping pliers：Wire crimping pliers, one of the tools for power line maintenance

Wire crimping pliers are a kind of hardware tools that use cold pressing to connect copper and aluminum wires. They are often used in the construction of aluminum stranded wire and steel core aluminum stranded wire. crimping pliers can be roughly divided into two categories: hand crimping and oil crimping. Hand crimping pliers are used for wire cross-sections of 35 mm2 and below, and gear crimping pliers or oil crimping pliers are used for wire cross-sections of 35 mm2 and above. With the development of the machinery manufacturing industry, more and more mechanical tools are available to electricians. Using these tools can not only greatly reduce labor intensity, but also increase work efficiency exponentially.

The wire crimping pliers are composed of a handle, a crimping mechanism, a cutting blade, and a wire stripping blade. The handle is used for holding, the crimping mechanism is used for crimping the wire and the terminal, and the cutting blade and the wire stripping blade are used to cut and strip the insulation layer of the wire. The working principle of the wire crimping pliers is to use the crimping mechanism to crimp the wire and the terminal to tightly connect the metal parts between the wire and the terminal. During the crimping process, the wire is clamped in the crimping mechanism, and the crimping mechanism is moved to the top of the terminal by manual operation, and a certain amount of pressure is applied to press the metal part between the wire and the terminal to form a firm connection.
