Abstract
The utility model discloses a kind of mini optical fibre heat-shrink tubes, it includes inner tube and is wrapped in the heat-shrink tube of said inner tube peripheral side, said inner tube is the hot melt adhesive of cylinder, its inner shaft has set up reserved optic fibre hole, the rectangular notch being connected to the reserved optic fibre hole is further opened in said inner tube, the inner wall of the rectangular notch both sides, which is equipped with, prevents the hangnail that mini optical fibre falls off out of described reserved optic fibre hole, is respectively arranged at the distance between described hangnail on the inner wall of the rectangular notch both sides and is less than mini optical fibre diameter.The utility model structural framing is exquisite, feasible process is high, before the mini optical fibre heat-shrink tube hot melt, said inner tube offers the hangnail for preventing optical fiber from falling off from said inner tube, to avoid mini optical fibre hot melt preceding easy to fall off, mini optical fibre is from distracted rectangular notch is radially put into improve the qualification rate of mini optical fibre heat-shrink tube welding.
Description
Technical field
The utility model is related to fiber optic communication field more particularly to a kind of mini optical fibre heat-shrink tube and its production technologies.
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 being put into heat-shrink tube in axial direction of the mini optical fibre along heat-shrink tube, mini optical fibre easily with the inner wall of heat-shrink tube occur friction and
Collision, the smaller optical fiber of toughness, which is easy to happen, to fracture, in addition when we select from heat-shrink tube radially to place optical fiber, i.e., from side
A rectangular notch for being parallel to axis is opened, but tiny optical fiber is easy to fall off from notch, therefore urgently seek a kind of solution
The certainly mini optical fibre heat-shrink tube of the above problem.
Utility model content
The purpose of this utility model is to provide a kind of mini optical fibre heat-shrink tube, solves mini optical fibre heat-shrink tube in the prior art
Caducous problem before the fine and mini optical fibre that breaks when welding heats.
In order to solve the above technical problems, the utility model adopts the following technical solution：
A kind of mini optical fibre heat-shrink tube comprising inner tube and the heat-shrink tube for being wrapped in said inner tube peripheral side, said inner tube
For cylindrical hot melt adhesive, inner shaft has set up reserved optic fibre hole, has been further opened in said inner tube and the reserved light
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 hangnail to fall off is respectively arranged at the distance between described hangnail on the inner wall of the rectangular notch both sides and 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.
Compared with prior art, the advantageous effects of the utility model：
The utility model reduces the disconnected fibre of mini optical fibre by opening up optical fiber in the placement channel radially of heat-shrink tube
Rate is provided with the hangnail for preventing mini optical fibre from falling off out of described reserved optic fibre hole, to substantially increase on placing channel
The success rate of optical fiber hot melt.

Specific implementation mode
As shown in Figs. 1-2, a kind of mini optical fibre heat-shrink tube
A kind of mini optical fibre heat-shrink tube of the present invention comprising inner tube 2 and the heat-shrink tube 3 for being wrapped in 2 peripheral side of said inner tube,
Said inner tube 2 is the hot melt adhesive of cylinder, and inner shaft offers reserved optic fibre hole 4 upwards, and specifically reserved optic fibre hole 4 passes through
Extrusion mechanism is further opened with the rectangular notch 5 being connected to the reserved optic fibre hole 4 at reserved optic fibre hole in said inner tube 2, described
The inner wall of 5 both sides of rectangular notch, which is equipped with, prevents the hangnail 6 that mini optical fibre 1 falls off out of the reserved optic fibre hole 4, opens up respectively
It is less than mini optical fibre diameter in the distance between the hangnail 6 on the inner wall of 5 both sides of the rectangular notch.
Specifically, the internal diameter of the reserved optic fibre hole 4 is more than the diameter of mini optical fibre 1, convenient for placing mini optical fibre.
Specifically, the internal diameter of the reserved optic fibre hole 4 is not more than 0.1mm.
Specifically, before hot melt, the length of the heat-shrink tube 3 is more than the length of said inner tube 2, when due to hot melt, heat-shrink tube
Heated can shrink shortens, in order to which ensure heat-shrink tube can suture inner tube.
Specifically, the rectangular notch 5 is an integral molding structure with the reserved optic fibre hole 4, it is easy to make quick.
Embodiment described above is only that the preferred embodiment of the utility model is described, not to the utility model
Range is defined, and under the premise of not departing from the spirit of the design of the utility model, those of ordinary skill in the art are new to this practicality
The various modifications and improvement that the technical solution of type is made should all fall into the protection domain of the utility model claims book determination
It is interior.
