Description
Technical field
The present invention relates to fiber optic communication field, more particularly to a kind of mini optical fibre heat-shrink tube and its production technology.
Background technology
In recent years, industry focuses on reducing always the area occupied of fiber optic network, it may be said that at 2005 or so with optical fiber
Supplier development goes out small-bend radius optical fiber, has just started to occur towards the trend of smaller optical cable and hardware advances.Therefore, have
The demand of mini optical fibre, due to the thinner smaller of the architectural characteristic of mini optical fibre and then toughness is smaller, in production, as shown in Figure 1,
When mini optical fibre is put into heat-shrink tube along in the axial direction of heat-shrink tube, mini optical fibre easily occur with the inner wall of heat-shrink tube friction and
Collision, the less optical fiber of toughness easily fractures, in addition when our selections radially place optical fiber from heat-shrink tube, i.e., from side
A rectangular notch parallel to axis is opened, but tiny optical fiber easily comes off from notch, therefore urgently seek a kind of solution
The certainly mini optical fibre heat-shrink tube of the above problem.
The content of the invention
The object of the present invention is to provide a kind of mini optical fibre heat-shrink tube, solves mini optical fibre heat-shrink tube welding in the prior art
When break caducous problem before fine and mini optical fibre hot melt.
In order to solve the above technical problems, the present invention adopts the following technical scheme that：
A kind of mini optical fibre heat-shrink tube, it includes inner tube and is wrapped in the heat-shrink tube of said inner tube outer circumferential side, said inner tube
For the hot melt adhesive of cylinder, its inner shaft offers reserved optic fibre hole, is further opened with said inner tube and the reserved light upwards
The rectangular notch of fine hole connection, the inner wall of the rectangular notch both sides, which is equipped with, prevents mini optical fibre out of described reserved optic fibre hole
The distance between the hangnail to come off, the hangnail being respectively arranged on the inner wall of the rectangular notch both sides is less than mini optical fibre
Diameter.
Further, the internal diameter of the reserved optic fibre hole is more than the diameter of mini optical fibre.
Further, the internal diameter of the reserved optic fibre hole is not more than 0.1mm.
Further, before hot melt, the length of the heat-shrink tube is more than the length of said inner tube.
Further, the rectangular notch is an integral molding structure with the reserved optic fibre hole.
Its technological process includes the following steps：
A, by inner tube by extrusion mechanism into the inner tube of the reserved optic fibre hole with hangnail；
B, the rectangular notch with hangnail is strutted by the inner tube Jing Guo step A by device for spreading and is put into mini optical fibre；
The internal diameter of heat-shrink tube is extended to 2.5 times of its former internal diameter C,；
D, the inner tube insertion Jing Guo step B by expanding heat-shrink tube and is made into heat-shrink tube heat shrinkable with hard-pressed bale inner tube and micro-
Type optical fiber.
Compared with prior art, advantageous effects of the invention：
The present invention reduces the disconnected fine rate of mini optical fibre by opening up placement passage radially of the optical fiber in heat-shrink tube,
The hangnail for preventing that mini optical fibre from coming off out of described reserved optic fibre hole is provided with passage is placed, so as to substantially increase optical fiber
The success rate of hot melt.
