Optical cable connection box with auxiliary device for gap filling and waterproofing

摘要

An optical cable connection box with an auxiliary device for gap filling and waterproofing is provided. The connection box includes a cable accessing end face, an auxiliary device for gap filling and waterproofing and an elastic shrinkable tube. The end face has a first hollow tubular column, and an optical cable to be waterproof processed by the elastic shrinkable tube passes therethrough as a dual cable after face to face bending, so that cable halfway splitting and halfway branching can be processed in the box without cutting off the cable. The auxiliary device cooperates with the optical cable in the hollow column, formerly a first waterproof structure where the auxiliary device is wrapped by the elastic shrinkable tube. At least the outside of the first hollow column and at least a portion of the auxiliary device are also wrapped by the elastic shrinkable tube forming a second waterproof structure.

主权项

1. A cable splice shell, comprising:
at least one end surface passing therethrough a first cable, wherein the first cable has a fiber-optic core therein and is bent in a U-shape without breaking the fiber-optic core, and the bent first cable has an inner part in the cable splice shell and an outer part out of the cable splice shell; at least a first hollow cylindrical tube formed on the end surface and passing therethrough the bent first cable; at least an auxiliary device cooperating with the outer part of the bent first cable to form a first waterproof structure; and at least a first elastic shrinkable tube covering an outer surface of the first hollow cylindrical tube and an outer surface of the auxiliary device to form a second waterproof structure.
