Problems solved by technology

However, when the entire top cover is fully opened, all components and devices in the fiber optic junction box will be completely exposed. The installed original communication lines cause interference or even damage
Therefore, the existing optical fiber junction box cannot provide maximum protection for the original communication lines

Abstract

The invention discloses an optical fiber junction box which comprises a shell for accommodating a wiring tray. The shell comprises a base and a top cover, wherein the top cover comprises at least one sub cover unit; and at least one of the sub cover units can be independently opened so as to open a corresponding region to be operated according to the actual operation requirement. Compared with the prior art, in each embodiment of the invention, the top cover of the optical fiber junction box comprises the sub cover units, and thus, when an operation only needs to be executed in the operation region covered by a certain sub cover unit, only the sub cover unit related to the operation needs to be opened without opening the whole top cover and other operation regions which are not related to the operation are still shielded by the shell, so that the interference, even damage, to an original mounted communication line can be reduced, even avoided, and the furthest safety protection is provided for the original communication line. Moreover, only the sub cover unit related to the operation needs to be opened, so the optical fiber junction box is simple and rapid to operate.

Description

technical field [0001] The invention relates to an optical fiber junction box, in particular to an optical fiber junction box with an improved top cover. Background technique [0002] Existing optical fiber junction boxes generally include a base and a top cover, both of which are molded as one piece. In the optical fiber junction box, there are operating areas such as a wiring operation area for inserting optical fibers, a fusion operation area for fusing trunk optical fibers, and a fiber coiling operation area. After the initial installation of the fiber optic junction box, if any operation area needs to be operated again, the entire top cover of the fiber optic junction box must be fully opened, and the entire top cover must be closed after the operation is completed. [0003] After the fiber optic junction box is installed for the first time, the most important operation is to insert the optical fiber to lead out the signal. For the existing fiber optic junction box, to...
