Description
Technical field
The present invention relates to fiber optic communication fields, and in particular to optical cable.
Background technique
Slotted core cable includes：Reinforcer, the fibre ribbon in mounting groove, envelopes bone at the skeleton with mounting groove
Frame block water band and cladding blocks water the oversheath of band.For the ease of identification, generallys use setting flag line or extrude rib
Target mode is distinguished to realize.
Wherein, mark line can fade at leisure over time, bring great inconvenience to later maintenance；By
It is the fillet extruded together with skeleton in rib mark, therefore, usually will appear interrupted phenomenon, it is bad to easily lead to extruding for skeleton.
The great advantage of slotted core cable be it is easily branched, optical cable can not destroyed to greatest extent and complete optical fiber or optical fiber
Branches of band.But in construction, due to the oversheath on the outside of skeleton, in order to achieve the purpose that branch, construction personnel can only lead to
Cross stripping be at least whole circle sheath can be only achieved identify required for fibre ribbon purpose, then carry out stripping skeleton grooves to realize
The branch of optical fiber or optical cable, this can destroy the overall structure of optical cable, open the conduit for originally not needing to destroy also by stripping.
Summary of the invention
The present invention is in view of the above-mentioned problems, propose a kind of optical cable.Existing optical cable is solved in branch, needs to peel off whole circle
Sheath could identify the problem of required fibre ribbon.
The technical solution adopted by the present invention is as follows：
A kind of optical cable, including：

It is adapted.That is the circle of outer profile one standard of composition of cover plate and skeleton cross section.
Optionally, the cover plate with magnetic medium has groove backwards to the side of reinforcer, and the magnetic medium is fixed
In groove.
This structure type can prevent magnetic medium enter in mounting groove influence fibre ribbon and use up magnetic medium can
It can be close to oversheath, so that detection device be facilitated to detect.
Optionally, the magnetic medium is magnetic powder, and magnetic powder is fixed in groove by alite paste.
Optionally, the manufacturing method of the cover plate with magnetic medium includes the following steps：
1) it is made by mold injection with reeded cover plate；
2) cover plate is cooled down by cooling trough；
3) cover plate is dried, removes cover plate surface moisture；
3) alite paste brush is entered in groove by gum brush；
4) magnetic powder is sprayed in groove, magnetic powder is relatively fixed firmly by alite paste and groove；
5) it is blown by the way that the nozzle of groove two sides is arranged in covering plate surface, removes the magnetic powder at the non-recessed place of cover plate.
Magnetic powder is sprayed in groove by first gluing again, keeps magnetic powder relatively fixed by alite paste and groove, this technique side
Formula is simple and reliable；Nozzle by the way that groove two sides are arranged in can quickly and effectively remove the magnetic powder at the non-recessed place of cover plate, protect
The neat and tidy at the non-recessed place of cover plate is demonstrate,proved, is prepared for the subsequent technique for coating the band that blocks water.
Optionally, the gum brush in the step 3) includes：
Brush body；

The more defeated glue branch pipes being spaced apart are arranged in brush body, and one end of defeated glue branch pipe is connected to bristle, another
End is pierced by brush body；
Defeated glue general pipeline, the one end for being pierced by brush body with each defeated glue branch pipe are connected to.
When practice, defeated glue general pipeline is pumped by glue and is connect with glue case, and defeated glue general pipeline is defeated by defeated glue branch pipe by alite paste
Enter into bristle, so that bristle continuously coats groove.
Optionally, the groove includes bottom wall and the sloped sidewall positioned at bottom wall two sides, and the bristle protrudes into groove
And it is contacted with the bottom wall of groove and sloped sidewall.
This structure type can prevent alite paste to be coated in outside groove, can guarantee the whole of the non-recessed place of cover plate
It is clean.
The beneficial effects of the invention are as follows：There are two effects for cover plate, first is that covering mounting groove, prevents the band insertion peace that blocks water
Tankage influences optical cable quality；Second is that the cover plate with magnetic medium can facilitate positioning in fiber cable branch, determines and need
The mounting groove pushed aside.
