Description

Technical Field

[0001] The invention relates to the field of optical fiber plugging and unplugging devices, in particular to a replaceable FC type optical fiber head plugging and unplugging tool. Background Art

[0002] At present, optical fibers have been widely used in secondary equipment cabinets in converter stations. Dense optical fibers are distributed in a limited space. It is difficult for maintenance personnel to plug and unplug optical fibers in the dense optical fiber area with their bare hands, which will inevitably cause damage to adjacent optical fibers and optical fiber heads to be removed.

[0003] When tightening or loosening the fiber head with a pliers-type fiber disassembly tool, due to the small space, it is impossible to hold it with both hands, and it can only be clamped with one hand. The force will be large or small, and the uneven force will easily cause the fiber head to be over-tightened or under-tightened. Over-tightening may cause damage to the fiber head and fiber thread. The next time it is damaged, the corresponding board can only be replaced to eliminate the fault, expanding the replacement range and causing unnecessary losses; if it is not tightened in place, it will cause unstable fiber transmission data and increase fiber attenuation. Summary of the invention

[0004] The invention mainly solves the problems existing in the prior art and provides a replaceable FC type optical fiber head plugging and pulling tool.

[0005] The present invention is achieved through the following technologies:

[0007] The method of using the present invention is as follows: insert the optical fiber into the interior of the fixed head and the rotating head through the axial opening 1 and the axial opening 2, and rotate it left and right so that the axial teeth on the optical fiber head mesh with the anti-slip teeth 1 and the anti-slip teeth 2, push the plug-in tool inward so that the outer shell of the optical fiber head is completely placed in the fixed head, turn the bolt so that the anti-slip teeth 2 are misaligned with the anti-slip teeth 1 and the axial teeth on the optical fiber head; rotate the plug-in tool to disassemble the optical fiber head; and the process is the opposite when reinstalling the optical fiber.

[0008] The beneficial effects of the present invention are:

[0009] 1. The fixed head and rotating head can be disassembled, and tools of different lengths can be replaced in time according to the density of optical fiber distribution and the bending radius of the optical fiber to improve work efficiency;

[0010] 2. The handle adopts a ratchet handle. When it is rotated to the dead angle of the arm, the handle is adjusted back to the correct force posture. This can not only prevent the problem of the optical fiber and the tool being twisted or entangled when removing the optical fiber head, but also prevent multiple clamping, damage to the optical fiber head and position correspondence errors, causing the intact optical fiber to be disassembled and installed.
