Optical fiber pre-connecting piece and terminal box therewith

Abstract

The invention discloses an optical fiber pre-connecting piece and a terminal box therewith. The optical fiber pre-connecting piece comprises pre-connecting joints and sealing sleeves; connection ports are arranged at joints and used for connecting optical fiber joints; the connection ports comprise core-inserting holes; optical fiber through holes form in the middle of the core-inserting holes; an oblique angle forms between the connection ports and the horizontal direction; the sealing sleeves are mounted outside the optical fiber joints; the pre-connecting joints are in connection with the sealing sleeves through clamping slots or screw threads. The pre-connecting joints of the optical fiber pre-connecting piece are mounted on the terminal box; pre-connecting optical fiber joints or quick optical fiber connectors can be directly mounted when the terminal box shell is not opened, and thus the piece and the terminal box can achieve plug and play, are saved in connection time, are convenient to quick mount and construct and are flexibly and quickly wired and changed on the site; besides the sealing sleeves can protect the pre-connecting joints and have the dust-proof and water-proof function.

Description

technical field [0001] The invention relates to the field of optical fiber connection equipment, in particular to an optical fiber pre-connection piece and a terminal box with the pre-connection piece. Background technique [0002] In recent years, with the rapid development of Internet services and the continuous improvement of broadband access technology, my country's fiber-to-the-home industry has ushered in a period of rapid development, and the corresponding supporting equipment for fiber-to-the-home has also been widely used. Outdoor pre-connected fiber optic terminal box is an indispensable telecommunications equipment for the realization of fiber-to-the-home. It is mainly used in the "last mile" access network of fiber-to-the-home. Install. At present, for most optical fiber terminal boxes, the lead wires or pigtails are generally installed and fixed on the adapter in the terminal box.

AI Technical Summary

Problems solved by technology

At present, for most optical fiber terminal boxes, the lead wires or pigtails are generally installed and fixed on the adapter in the terminal box. Connected with fast cable connectors or pigtails; this not only delays the construction time, but also may affect the communication signals of customers who have already opened, and may also damage the internal fiber routing that has been constructed.
