Description

Technical Field

[0001] The utility model relates to the technical field of optical fibers, in particular to a focusing matrix optical fiber which is easy to disassemble. Background Art

[0002] In automated machinery or automated production lines, we often see sensors with functions such as detection, mobile positioning, and good product screening to meet various needs and purposes. Among them, photoelectric proximity sensors use the signal feedback of the penetration, reflection, or shielding of the light beam, and then use the transmission line to connect to the mechanical control end or signal receiving end to calculate the relevant information of the detection.

[0003] A Chinese patent with publication number (CN207882500U) discloses a focusing matrix optical fiber, including an optical fiber connector composed of an optical fiber cable protection component, and a shell. The shell has a positioning member and a matrix member inside. The positioning member has a groove for setting at least one curved cylinder, and the matrix member can be embedded and fixed in the shell with the positioning member. When the optical fiber connector is connected to the shell, the light beam transmitted by the optical fiber connector can be projected at a fixed angle through the curved cylinder via the matrix member. In addition to effectively suppressing malfunctions caused by light beam refraction, the optical fiber connector is connected to the shell into an integrated design with the help of the shell, so that the inconvenience of adjustment of the conventional structure can be improved, and small objects under test can be detected.

[0004] The defect of the above-mentioned selected technology is that the positioning piece has a groove for accommodating at least one curved cylinder, and the positioning piece is embedded and fixed in the shell with the matrix piece. There are two rectangular grooves on the upper and lower sides of the shell respectively. The positioning piece and the corresponding surface of the matrix piece have protrusions for easy embedding. However, when the number of curved cylinders needs to be increased or decreased, a tool must be used to press the protrusion out of the rectangular groove before the positioning piece and the matrix piece can be removed, which makes disassembly very inconvenient.
