Description

Technical Field

[0001] The utility model relates to the technical field of communications, and particularly to an optical cable splice closure. Background Art

[0002] Optical cable splice closures are widely used in the field of communications. An optical cable splice closure is internally provided with optical cable connectors. Through the optical cable connectors, an optical cable splice closure can realize functions such as optical fiber fusion splicing, wiring, dispatching, and testing between optical cables. It is a hub for signal transmission, dispatching, and conversion between optical signal transceiver devices, and has functions such as optical signal dispatching and switching.

[0003] In a communication line, the failure rate of the optical cable in the optical cable splice closure is relatively high. For example, due to poor sealing performance of the optical cable splice closure, water enters the optical cable splice closure, resulting in increased optical cable loss and fiber breakage; for an overhead optical cable affected by the external environment, poor connection due to thermal expansion and contraction, etc. To repair the optical cable in the optical cable splice closure, the staff needs to open the box cover multiple times. However, since the box body and the box cover are connected by multiple bolts, each bolt needs to be screwed multiple times to complete disassembly and assembly, which is cumbersome and has low work efficiency. To solve this problem, an optical cable splice closure is proposed. Summary of the Utility Model
