Abstract

The utility model aims to disclose an indoor wall type covered optical cable branching device. An optical cable is branched around a circular structure by the aid of a circular fiber coiling seat when passing through the inside of a branching box, and the bending radius of the optical cable is limited, so that bending loss is ensured not to increase. Moreover, circular arc-shaped optical cable guide walls are arranged on the periphery of the device, so that the optical cable can pass through two adjacent pipe clamp fixing seats in a softly bending manner. Besides, the bending radius of the optical cable is limited, so that the loss is ensured not to increase while the probability of breaking the optical cable by accident at corners is decreased greatly. Various types of corrugated pipes can be fixed well easily by the aid of a position-adjustable pipe clamp. The indoor wall type covered optical cable branching device is simple and easy in operation, and the purposes of the indoor wall type covered optical cable branching device are achieved.

In sum, at the defective of prior art, need a kind of indoor wall formula covered wire cable branch unit especially, to solve above-mentioned problem.

The utility model content

The purpose of this utility model is to provide a kind of indoor wall formula covered wire cable branch unit; solve the defective of above-mentioned prior art; covered wire cable is carried out branch, comes together; protective effect is arranged when the branch and limited the bending radius of covered wire cable for covered wire cable; reduced loss; solved the problem of optical cable fracture, simple to operate, be convenient to install.

The technical matters that the utility model solved can realize by the following technical solutions:

A kind of indoor wall formula covered wire cable branch unit, it is characterized in that, it comprises lid, base and pipe clamp, be provided with the fine seat of circular discs in the center of described base, the center of the fine seat of described circular discs is provided with the optical cable through hole, side margins place at described base is provided with the pipe clamp holder respectively, be provided with the adjustable tooth bar of serrate in the middle of the described pipe clamp holder, be connected to each other by circular arc optical cable guide wall between the adjacent described pipe clamp holder, the installation screw be set at the end points place of described base; Described pipe clamp matches with described pipe clamp holder, and described pipe clamp is provided with the adjustable tooth bar that matches with the adjustable tooth bar of described serrate; Be provided with holes for optical cables and corresponding respectively at the side margins place of described lid with the position of described pipe clamp holder.

In an embodiment of the present utility model, described pipe clamp holder is connected on the described base by the fastener of bottom.

In an embodiment of the present utility model, the bottom of described pipe clamp is provided with card base, and the centre of described pipe clamp holder is provided with draw-in groove, and described card base matches with described draw-in groove.

Indoor wall formula covered wire cable branch unit of the present utility model compared with prior art has following advantage:

(1) adopted the fine seat of circular discs of inner uniqueness, made optical cable when inner branch, reduce loss, the possibility that the quilt that reduces fractures;

(2) when four sides of base were provided with circular arc optical cable guide wall and make optical cable at cabling, bending radius can be not excessive, and radius-of-curvature is big;

(3) fixedly the time, used the pipe clamp of adjustable position, can both fix simple and operation easily easily for the corrugated tube of each model.

Indoor wall formula covered wire cable branch unit of the present utility model, optical cable makes optical cable come branch around circular configuration by the fine seat of circular discs by dividing box inside the time, limited its bending radius, guarantee that bending loss can not increase, and when four sides are provided with circular arc optical cable guide wall and allow optical cable pass through contiguous two pipe clamp holders, optical cable can pass through in soft bending, and limited its bending radius, when having guaranteed that loss does not increase, lower the probability that optical cable is on the corner fractureed because of carelessness greatly, the pipe clamp of utilization adjustable position, corrugated tube for each model can both fix easily, simple and easy operation realizes the purpose of this utility model.

Characteristics of the present utility model can be consulted the detailed description of the graphic and following better embodiment of this case and be obtained to be well understood to.
