Description

Technical Field

[0001] The utility model relates to the field of optical fibers, in particular to an optical fiber which is convenient for stripping. Background Art

[0002] Optical fiber is the abbreviation of optical fiber. It is a fiber made of glass or plastic that can be used as a light transmission tool. The transmission principle is "total reflection of light". Its main function is to transmit information. Optical fiber has the advantages of wide bandwidth, low loss, light weight, low attenuation, and no electromagnetic interference. In daily life, since the conduction loss of light in optical fiber is much lower than the conduction loss of electricity in wires, optical fiber is used for long-distance information transmission. When wiring, the outer skin of the optical fiber port needs to be stripped off, which can easily damage the core.

[0003] Chinese patent CN218675415U discloses an optical fiber that is easy to peel, including a protective sleeve, an arc plate and a protective layer. The outer surface of the protective sleeve is provided with a tearing groove along the circumferential direction, a tearing line is provided in the tearing groove, and the other end of the tearing line extends to the inner wall of the protective layer. A groove is provided on one end surface of the protective sleeve, a convex edge is inserted in the groove, and the other end of the convex edge is fixedly connected to the protective sleeve. A circular groove is provided on the upper surface of the protective sleeve, and a guide groove and an annular clamping groove are provided on the circumferential surface of the circular groove. A connecting rod is provided in the circular groove. When the utility model is peeling, the connecting rod is rotated by hand to make the clamping block It is pulled out from the protective sleeve, and the protective sleeve, arc plate and protective layer can be torn by pulling the tear line, so as to peel off the optical fiber core. During use, the tear line in which tear groove is used for tearing can be selected according to the required stripping length, so as to facilitate measurement and make the stripping length uniform. However, the optical fiber is not easy to produce, and the main body is all connected by card connection, which is prone to water leakage. Generally, a wire head separated from the main body is set at the end of the optical fiber to protect the core of the port. The wire head is not connected to the main body, which makes the exposed part easy to break and damage.

[0004] Therefore, those skilled in the art provide an optical fiber that is easy to strip, so as to solve the problems raised in the above background technology. Utility Model Content
