Description

Technical Field

[0001] The utility model relates to a lighting pen, in particular to a lighting pen for detecting optical fiber after fusion splicing, and belongs to the technical field of optical fiber detection. Background Art

[0002] The full name of optical fiber is optical fiber. It is a bendable pure glass fiber made of glass or plastic. It is also a light transmission tool that uses the principle of total internal reflection to transmit light in these fibers. Optical fiber is mainly composed of a core and a cladding. The core and cladding are concentric glass cylinders. The refractive index n1 of the core is slightly higher than the refractive index n2 of the cladding. When the light wave enters from the end face of the optical fiber at a small angle, it will be fully or partially reflected at the interface between the core and the cladding to the interface on the other side and then reflected again. Such repeated reflections allow the light signal to propagate forward. It is divided into quartz optical fiber, multi-component glass optical fiber, plastic-clad quartz core optical fiber and all-plastic optical fiber according to the material. It is divided into step-index optical fiber and gradient-index optical fiber according to the structure of the optical fiber. The principle is that the transmitting device at one end of the optical fiber uses a light-emitting diode or a laser to send a light pulse into the optical fiber, and the receiving device at the other end of the optical fiber uses a photosensitive component to detect the pulse. The optical fiber needs to be detected after fusion splicing. At this time, a post-fusion fiber fusion detection lighting pen is needed.

[0003] Among them, the application number is "CN201620742326.6" which is a fiber optic pen, comprising a pen cap, a transparent pen tube, a pen tip, an LED lamp, a fiber optic ribbon and an ejection block. One end of the transparent pen tube is connected to the pen cap, and the other end is connected to the pen tip. The LED lamp is arranged in the pen cap, the fiber optic ribbon is arranged in the transparent pen tube, characters are arranged on the fiber optic ribbon, and one end of the fiber optic ribbon is located on the LED lamp, a guide groove is arranged on the inner wall of the pen tip, a wedge is arranged on the inner wall of one end of the transparent pen tube corresponding to the pen tip, the ejection block is arranged in the pen tip, and a guide block is arranged at one end of the ejection block, and a bevel groove is arranged at the other end, the wedge is in contact with the bevel groove to push the ejection block, and the guide block is arranged in the guide groove; the beneficial effects of the utility model are: the structure is reasonable, it can produce light effects with characters, and does not affect normal writing.

[0004] However, the above-mentioned method still has certain shortcomings when used. Since there is no structure or component that provides anti-lost function and carrying function, the staff can only hold and carry it. It is easy to drop and lose during the process of holding and carrying and during the process of holding and using, which is not convenient for better anti-lost and carrying. Utility Model Content
