Technical Field

[0001] The utility model relates to the technical field of optical cable connection and fixing devices, in particular to a transmission optical cable line connection and fixing device. Background Art

[0002] A fiber optic cable splice closure (Fiber Optic Joint Closure) is a device used to protect and connect optical fibers and plays a vital role in fiber optic communication networks. Its primary function is to provide a secure environment, protecting the fiber connection points from physical damage and environmental influences while ensuring the transmission quality and stability of optical signals.

[0003] The conventional junction box for connecting and fixing optical cable lines mainly consists of a lower junction cover and an upper junction cover. Specifically, in the process of fixing the cable, the staff first unscrews the fixing screws, further removes the fixing piece, and then places the optical cable line into the wire hole. Afterwards, the fixing piece is placed and the fixing screws are tightened so that the fixing piece is crimped and fixed to the wire body inside the wire hole. The fixing operation process is relatively cumbersome. Therefore, it is necessary to improve the conventional junction box. Utility Model Content
