Abstract
The present invention discloses optical fiber breakpoint detector, is related to optical-fibre communications engineering field.Optical fiber breakpoint detector is in the test tube shape of upper end opening, and the optical fiber breakpoint detector bottom is provided with a convex lens, and the optical fiber breakpoint detector inner wall is equipped with pairs of metallic channel, the metallic channel positional symmetry arrangement.Optical fiber breakpoint detector of the invention is applicable to place covered wire cable or optical patchcord, to be not easily broken optical fiber；Light is gathered by the convex lens of optical fiber breakpoint detector bottom, makes it easy to see whether that light beam outflow comes.
Description
Technical field
The present invention relates to optical-fibre communications engineering fields, and in particular to optical fiber breakpoint detector.
Background technique
Since optical fiber can fracture when being laid with installation, to make optical path that can not propagate, lead to signal transmission failure.It is logical
It is whether unimpeded in detection fiber in normal situation, it is general using being irradiated in optical fiber one end with laser pen, it has been seen whether in the other end
Light beam outflow comes, to judge whether optical fiber is unobstructed.
In Practical Project, fiber cut cannot usually be irradiated in initial point with laser pen when looking for breakpoints of optical fiber,
Again by the micro- folding in optical fiber middle section, when being folded into certain angle, if this section unobstructed, it will have light spilling, to judge this
Section be it is normal, successively reduce detection range；But the bad control of bending angle in practice, the big optical fiber that can fracture is bent, it is curved
Rolled over small then light can not appear, so a fixed equipment is needed to be detected.
Summary of the invention
The present invention in the prior art by hand bending optical fiber when easily lead to and fracture optical fiber or what optical fiber can not appear asks
It inscribes and proposes optical fiber breakpoint detector, which is applicable to place covered wire cable or optical patchcord, thus not
Frangibility optical fiber.
Technical scheme is as follows：
Optical fiber breakpoint detector is in the test tube shape of upper end opening, and the optical fiber breakpoint detector bottom is provided with a convex lens, institute
It states optical fiber breakpoint detector inner wall and pairs of metallic channel, the metallic channel positional symmetry arrangement is installed.
Above-mentioned metallic channel has two pairs.
Above-mentioned two pairs of metallic channels are respectively to be used to place the first metallic channel of covered wire cable and for placing optical patchcord
Second metallic channel.
The width of above-mentioned first metallic channel is slightly larger than the diameter 5mm of covered wire cable.
The width of above-mentioned second metallic channel is slightly larger than the diameter 4mm of optical patchcord.
The material of above-mentioned optical fiber breakpoint detector is PVC.
Beneficial effects of the present invention：Optical fiber breakpoint detector of the invention is applicable to place covered wire cable or optical fiber is jumped
Line, to be not easily broken optical fiber；Light is gathered by the convex lens of optical fiber breakpoint detector bottom, makes it easy to see whether
There is light beam outflow.
Detailed description of the invention
Fig. 1 is optical fiber breakpoint detector longitudinal section of the present invention；
Fig. 2 is optical fiber breakpoint detector longitudinal section of the present invention；
Fig. 3 is optical fiber breakpoint detector top view of the present invention.
Specific embodiment
In order to better illustrate the present invention, it is further described now in conjunction with examples and drawings.
Optical fiber breakpoint detector is in the test tube shape of upper end opening, and the optical fiber breakpoint detector bottom is provided with a convex lens
3, the optical fiber breakpoint detector inner wall is equipped with pairs of metallic channel, the metallic channel positional symmetry arrangement.
Further, metallic channel has two pairs, and two pairs of metallic channels are respectively 1 He of the first metallic channel for being used to place covered wire cable
For placing the second metallic channel 2 of optical patchcord；The width of first metallic channel 1 is slightly larger than the diameter 5mm of covered wire cable, and second leads
The width of wire casing 2 is slightly larger than the diameter 4mm of optical patchcord, facilitates and places covered wire cable and optical patchcord.
Further, the material of optical fiber breakpoint detector is PVC.
The working principle of optical fiber breakpoint detector of the present invention：
When whether having breakpoint if necessary to detect covered wire cable, then covered wire cable bending is placed in the first metallic channel 1, first
Initial point is irradiated with laser pen, has been seen whether that light beam outflow comes from convex lens 3, has been come if any light beam outflow, then illustrate rubber-insulated wire light
Cable has breakpoint herein, such as comes without light beam outflow, then illustrates covered wire cable herein without breakpoint.
When whether having breakpoint if necessary to detection fiber wire jumper, then optical patchcord bending is placed in the second metallic channel 2,
It is irradiated in initial point with laser pen, has seen whether that light beam outflow comes from convex lens 3, come if any light beam outflow, then illustrate light
Fine wire jumper has breakpoint herein, such as comes without light beam outflow, then illustrates optical patchcord herein without breakpoint.
