Technical Field

The utility model relates to the technical field of optical fiber wire stripping, in particular to a hot stripping pliers with a wire cutting function.

Background

Before the fusion splicing operation, the optical fiber needs to be cut and the coating layer stripped, so that a stripping tool is needed. The traditional fiber stripping tool is generally provided with a miller clamp and a hot stripper clamp (clamp), when the miller clamp is used for stripping the fiber, the miller clamp can remove the protective skin at the outermost layer of the fiber and the coating layer coated on the surface of the fiber core, but the miller clamp needs higher skill to be used, otherwise, the fiber core is easily damaged, the welding effect is influenced, the miller clamp has good effect in stripping the fiber of the single-core fiber, the fiber stripping effect on the ribbon fiber is not ideal, and the coating layer of the ribbon fiber cannot be completely stripped due to the defects of structural design. The hot stripping pliers generally soften the coating layer on the surface of the fiber core through heating, and strip the fiber core by using a cutter, so that the hot stripping pliers have good stripping effect and less damage to the fiber core, are suitable for simultaneously stripping the coating layer from a single fiber core and a plurality of fiber cores, and are particularly suitable for occasions with high fiber stripping requirements. However, the existing hot stripping pliers generally only can remove the coating layer of the fiber core, but cannot remove the protective skin of the outermost layer of the optical fiber, and the protective skin of the outermost layer of the optical fiber needs to be removed by other tools, so that the function is single, and when the hot stripping pliers are used for outgoing operation, the tools for removing the protective skin and the hot stripping pliers are additionally arranged, so that the hot stripping pliers are inconvenient to carry.

The utility model aims to solve the technical problem that the existing hot stripping pliers have single function and cannot directly strip the rubber-insulated wire optical fiber.
