Description

Technical Field

[0001] This utility model relates to a quick-installation and detachable fiber optic connector tail structure that is anti-rotation and tensile resistant, and in particular to a tail structure related to the field of fiber optic connector assembly process. Background Technology

[0002] Fiber optic connectors are crucial products in optical communication systems, widely used due to their advantages such as resistance to electromagnetic interference, high transmission rates, and lower cost compared to copper connectors. However, when fiber optic connectors are used with optical cables, the cables are susceptible to movement under external forces during actual use, leading to damage or breakage of the internal optical fibers. Traditionally, two methods are used: one integrates the upper and lower pressure plates into a single unit, directly connecting it to the splitter with screws or adhesive; the other uses screws to lock the splitter to both the upper and lower pressure plates, requiring thread-locking adhesive to prevent loosening over time. Both methods result in low assembly efficiency and inconvenient maintenance. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a fiber optic connector tail structure that is easy to use, simple to operate, stable and reliable, and resistant to twisting and tension.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a fiber optic connector tail structure that can be quickly installed and removed and is anti-spinning and tensile resistant, including a lower pressure plate, an upper pressure plate, a splitter and an optical cable. The lower pressure plate is connected to the upper pressure plate, the splitter cooperates with the grooves of the lower pressure plate and the upper pressure plate, and the optical cable is connected to the splitter.

[0005] Furthermore, the lower pressure plate has an annular groove, and one side of the groove has an inner circular opening. This inner circular opening cooperates with the outer circular opening of the splitter to provide an anti-rotation function.

[0006] Furthermore, the upper pressure plate has an annular groove that engages with the outer circular step of the splitter (2).

[0007] Furthermore, the splitter has an annular boss, and one side of the annular boss has an outer circular flat opening.

[0008] The beneficial effects of this utility model are as follows: by utilizing the fiber optic connector tail structure of this application, which is quick to install and remove and has anti-spinning and tensile strength, after the optical cable is connected to the splitter, it is only necessary to mate the annular boss of the splitter with the annular groove of the lower pressure plate and the upper pressure plate, and align the outer circular flat opening on one side of the annular boss of the splitter with the inner circular flat opening on one side of the annular groove of the lower pressure plate, so as to realize the anti-spinning and tensile strength function of the optical cable, and the assembly and disassembly are simple and convenient.

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The illustrated fiber optic connector tail structure, which is quick-installing, detachable, and resistant to twisting and tensile stress, includes a lower pressure plate 1, an upper pressure plate 3, and a splitter 2. The lower pressure plate 1 is connected to the upper pressure plate 3, and the splitter 2 mates with the grooves of the lower pressure plate 1 and the upper pressure plate 3. The optical cable 4 is connected to the splitter 2. The connection between the lower pressure plate 1 and the upper pressure plate 3 can be achieved using different processes, such as screw connection; similarly, the connection between the optical cable 4 and the splitter 2 can also be achieved using various processes, such as potting.

[0017] To ensure assembly accuracy, the axial dimensions and tolerances of the annular grooves of the lower pressure plate 1 and the upper pressure plate 3 in this application should be consistent, and they should be designed to match the annular boss of the distributor 2.

[0018] In order to limit the circumferential movement of the optical cable, the lower pressure plate 1 of this application has an inner circular opening on one side of the annular groove. This inner circular opening is mainly used for circumferential positioning.

[0019] In order to accommodate tail accessories of different types of connectors, the lower pressure plate 1 and the upper pressure plate 3 of this application can be designed in various other shapes to achieve mating.

[0020] By utilizing the fiber optic connector tail structure of this application, which allows for quick assembly and disassembly and is resistant to rotation and tension, once the optical cable is connected to the splitter, it is only necessary to mate the annular boss of the splitter with the annular grooves of the lower and upper pressure plates. Aligning the outer circular opening on one side of the annular boss of the splitter with the inner circular opening on one side of the annular groove of the lower pressure plate will achieve the anti-rotation and tension function of the optical cable, and the assembly and disassembly will be simple and convenient.
