Description

Optical fiber stripping pliers, its components and methods of use

Technical field

The invention relates to an optical fiber end processing tool and a method for using the same, in particular to an optical fiber stripping pliers and a method for using the same.

Background technique

Optical fiber stripper is a tool used to strip the outer coating of optical fiber. Existing fiber stripping pliers usually include a jaw section and a clamp handle. The two clamp handles are hinged together through a shaft. When the jaw sections are engaged together, the optical fiber held in the jaw is clamped. Pulling the optical fiber will wrap the optical fiber. The coating is peeled off.

Existing optical fiber stripping pliers, such as the Chinese invention patent 201310353466.5 authorized and announced on June 8, 2016, as shown in FIG. 1, relate to a stripping pliers, which includes two pliers handles, each of which includes a jaw at one end Section, the handle section at the other end and the hinge section between the jaw section and the handle section, the two jaw handles are hinged at their respective hinge sections by pins, and at least one jaw handle handle section is provided for adjusting the jaw width Quick adjustment device. When adjusting the bite width of the jaws, the wire stripping pliers of the invention can adjust the bite width of the jaws to a large extent by gently pulling the wrench, and the debugging speed is fast and the use is convenient.

In the Chinese utility model patent 201820441006.6, a wire stripper is also disclosed. As shown in FIG. 2, it includes a first clamp body and a second clamp body. The first clamp body is connected with a first clamp handle and a second clamp body A second clamp handle is connected to the upper portion, and the first clamp body and the second clamp body are hinged to the same pin, and a compression spring for expanding the two is arranged between the first clamp body and the second clamp body. The first clamp body Both the blades of the second pliers body are provided with wire stripping grooves for stripping wire. The first pliers body is fixedly connected with a mounting block, and the mounting blocks are threadedly connected to abut when the first pliers body and the second pliers body are closed The threaded rod of the second pliers body, and the axial direction of the threaded rod is perpendicular to the pin.
