Abstract

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.

Abstract

An optical cable connection casing includes at least one cable in-out end surface on which at least one connection part and at least one first hollow tubular column are located. The connection part and the first hollow tubular column allow the optical cable to pass in and out the connection casing through the connection part and the first hollow tubular column in the form of double optical cables after the optical cable being oppositely bent without cutting off the optical fiber core of the optical cable, respectively; wherein the optical cable will be guided and connected to a branching halfway.

Abstract

A wire connection and distribution casing with a connecting part, hollow pipe columns and a connected part for communication cables includes at least one cable inlet and outlet end face and at least one connected part. At least one connecting part and at least one hollow pipe column which is provided for the communication cables penetrating through the cable inlet and outlet end face and entering into the wire connection and distribution casing for the communication cables are formed on the cable inlet and outlet end face, and the communication cables which are to penetrate through the hollow pipe columns form waterproof structures by means of elastic shrinkable pipes. The connected part may form a waterproof structure by combining with the connecting part. The invention involves many problems which result from the waterproof means of the wire connection and distribution casing for the communication cables in the prior art.

Abstract

A waterproof communication cable connection box includes a protective cover, a cable pass-through end surface, a hollow cylindrical pipe formed on the cable pass-through end surface, an elastic rubber shrinking pipe, and a flexible hard plastic strip provided on the inner wall of the elastic rubber shrinking pipe. The plastic strip will be removed after a cable passes through the cable connection box so that the elastic rubber shrinking pipe closely covers the hollow cylindrical pipe and the cable part exposing outside of the hollow cylindrical pipe.
