Description

Technical Field

[0001] The utility model relates to the technical field of ribbon pigtails, in particular to a ribbon pigtail with a branching structure. Background Art

[0002] Pigtails are also called pigtails. They have a connector at only one end, and the other end is the broken end of an optical cable core. They are connected to other optical cable cores through fusion splicing. They are often found in optical fiber terminal boxes and are used to connect optical cables to optical fiber transceivers (couplers, jumpers, etc. are also used in between). In the existing technology, after the pigtail passes through the branch box to branch the optical cable, the optical cable after branching will be entangled because there is no branching limit structure inside the branch box, which is not convenient for the installation of the branch box. In addition, the outlet of the optical cable on the branch box is a right angle. Because the branch box is integrally injection molded, the rounded corners at the outlet of the optical cable on the branch box are small and cannot be injection molded. When the optical cable is folded up and down, creases are easily formed on the outer surface of the optical cable, which is easy to damage the optical cable. For this reason, a ribbon pigtail with a branching structure is proposed to protect the optical cable. Summary of the invention

[0003] The utility model aims to solve the above problems and provides a ribbon-shaped pigtail with a branching structure.

[0004] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a ribbon-shaped pigtail with a branching structure, which is characterized by including a pigtail composed of a plurality of optical cables and a branching box installed on the pigtail to branch the optical cables; a plurality of branching grooves for branching the optical cables are arranged in the branch box; and an extended protective cover for protecting the optical cables is inserted on the branch box.

[0005] Preferably, the extended protective cover on the branch box comprises a lower protective cover and an upper protective cover installed on the lower protective cover.

[0006] Preferably, both the lower protective cover and the upper protective cover are provided with guiding arc surfaces to prevent the optical cable from breaking.

[0007] Preferably, the lower protective cover is provided with a plurality of branching grooves adapted to the optical cables.

[0008] Preferably, the lower protective cover is further provided with an inserting boss; and the branch box is provided with an inserting groove adapted to the inserting boss.

[0009] Preferably, the branch box comprises a branch bottom shell having a branch groove and a branch upper cover installed on the branch bottom shell.

[0010] Preferably, the branch bottom shell is also provided with a pigtail inlet hole for facilitating the entry of the pigtail.

[0011] The beneficial effects of the utility model are as follows: by utilizing the branching grooves in the branch box to branch a plurality of optical cables in the pigtail, entanglement between the optical cables is prevented, thereby improving the convenience of installation.

[0012] The extended protective cover is used to protect the optical cable, thereby preventing the right angle of the branching groove on the branch box from easily causing creases on the folded optical cable, thereby damaging the surface of the optical cable, thereby protecting the optical cable.
