Optical cable down-lead plugging cap

Abstract

The invention relates to a special optical fiber down-lead pipe waterproof facility for electric power communication, which is composed of a two-section shell and an internal waterproof material. The two two-section shell is fixed through a buckle, a seaming position is provided with an occlusion buckling edge, and the waterproof material is used for tightly sealing a plugging cap and an optical cable, so as to prevent rain water from entering a down-lead pipe. The shell of the plugging cap is provided with a replaceable optical cable information clamping sleeve. The optical cable service is not interrupted during installation and maintenance, and the operation is very simple and easy. The problem that the optical cable down-lead pipe is not prone to installation and is not tight in plugging is solved. The problem that the optical cable information is inaccurate is solved. The optical cable information communication service cannot be interrupted in installation and maintenance, and the secure operation of the information communication network is ensured.

Description

technical field [0001] The invention relates to a waterproof facility for downconducting tubes of special optical cables for electric power communication, in particular to a sealing cap for downconducting optical cables, which is mainly suitable for the sealing of downconducting optical cables in substations above 66KV, and belongs to the application field of electric power communication. Background technique [0002] In the past, the sealing method of the optical cable downpipe used sleeve type heat-shrinkable tube and fireproof mud for sealing: it was necessary to interrupt the information communication service of the downconducting optical cable during installation and maintenance, resulting in a long installation and maintenance period, which affected the normal operation of the information communication service; After being exposed to wind and sun, it is easy to dry, crack and fail, resulting in water accumulation in the lower part of the downcomer of the optical cable a...
