Abstract

An outdoor optical fiber splicing box, a cable storage structure is fixed at the bottom of the inner cavity, a plurality of wiring structures are stacked on the upper side of the cable storage structure, and two sides of the wiring structure are provided with a multi-fiber supporting mechanism and a single-fiber supporting mechanism, which are fixed at the bottom of the inner cavity. The single-fiber and multi-fiber supporting mechanisms are all arranged on the side of the wiring structure. The box body is provided with a first and a second cable inlet/outlets, and the first cable inlet/outlet is provided with a single optical fiber waterproof structure. The second cable inlet/outlet is provided with a multi-fiber waterproof structure, and the waterproof effect is good. At the same time, the single-fiber and multi-fiber supporting mechanisms can protect the optical fiber cable from vibration, impact, cable stretching, and twisting.

An optical fiber splicing box, comprising a box body and a box cover, the box body and the box cover are buckled, and the box body is provided with a first opening facing upward, the box body is provided with an inner cavity, wherein a first waterproof ring is provided between the box body and the box cover, the inner cavity comprises a bottom, and a side wall of the box body is provided with a first cable inlet/outlet that allows a single fiber cable with a connector to enter the inner cavity, a second cable inlet/outlet for a plurality of straight-through cables to enter the inner cavity, and a cable storage structure is fixed at the bottom of the inner cavity, and a top of cable storage structure is fixed with a plurality of stacked wiring structures, a first cable positioning structure and a second cable positioning structure are arranged in the box body, a plurality of first cable inlet/outlets are provided and are respectively arranged on both sides of the cable storage structure, and a plurality of the second cable inlet/outlets are provided and are respectively arranged on both sides of the cable storage structure, the first cable positioning structure is arranged between the first cable inlet/outlet and the wiring structure, and the second cable positioning structure is arranged between the second cable inlet/outlet and the wiring structure, a first waterproof structure is arranged between the first cable inlet/outlet and the optical fiber cable, and a second waterproof structure is arranged between the second cable inlet/outlet and the optical fiber cable;

wherein the box body comprises a left side wall, a right side wall, a front side wall and a rear side wall, wherein first upper openings of the left side wall and the right side wall are respectively provided with first flange structures extending toward the outside, the first flange structure is provided with a first half-through hole penetrating the left side wall or the right side wall, and the box cover is provided with a second flange structure extending toward the outside and corresponding to the first flange structure, the second flange structure is provided with a second half-through hole, and the first half-through hole and the second half-through hole are combined to form the first cable inlet/outlet.
