Description
Technical field
The utility model relates to naked fine hot melt field, refers in particular to a kind of structure of naked fine fuse unit.
Background technology
Along with the sustained and rapid development of internet, online new business emerges in an endless stream, and particularly begins in recent years the business such as fashionable online game, video conferencing, video request program, so that people continue to increase the demand of network insertion bandwidth.
, wireless access technology wired with other compared, optical fiber access bandwidth capacity and apart from aspect have impayable advantage.
In the FTTH engineering, user's house wiring is the most complicated link, and covered wire cable cooperates the type field hot-melt type quick connector as the substitute of traditional inside cable, conveniently for the user provides the broadband, and the voice and video service.The type field hot-melt type quick connector is the connector that open at the most suitable current FTTH scene, but its popularity rate is lower, and one of its reason is that the success ratio of type field hot-melt type quick connector is very low.This is relevant with the thermoplastic sleeve pipe that the outer surface cover of naked fibre has.In optical fiber fusion welding technology, each class standard and textbook all have detailed and clear and definite introduction about naked fibre to melting, and naked fibre to molten high-level efficiency in the cable connection and the important guarantee of high stability of having become, thereby therefore naked fine fragility also become a very crucial problem.For this reason when two fused fiber splices are finished, carry out thermoplastic after usually will packaging the thermoplastic sleeve pipe.This is for the dynamics of strengthening naked fibre and intensity.Thermoplastic sleeve pipe heating time, can slowly shrink, and solidify, nakedly finely can scald naked fibre if run into during contraction, make that naked fibre is impaired to cause its obstructed light, and make on-the-spot welding failure.
The utility model content
The purpose of this utility model is the problem that exists in order to overcome prior art, and a kind of structure of naked fine fuse unit is provided, and can make naked fibre protecting naked fibre not injured by the thermoplastic sleeve pipe when molten, to improve naked fibre to molten success ratio.
The purpose of this utility model is achieved through the following technical solutions:
A kind of structure of naked fine fuse unit is characterized in that comprising:
Naked fine 32, be the naked fibre of standard of being opened stripping by covered wire cable 34, diameter is 0.125mm, naked fine end points is connected in hot melting connector 31;
Naked fine protective casing 10 is long tubes, and its pipe range direction is provided with notch 11, and described naked fine 32 are embedded in the naked fine protective casing 10 by this notch 11; The tube wall of naked fine protection tube 10 is provided with a plurality of manholes 14;
Described standard is naked fine to adopt that SMC is composite material moulded to be made.
The width of described notch 11 is between 0.125mm to 0.2mm.
Described a plurality of manhole 14 spread configurations are in the position of nearly notch 11.
Outer wall 12 diameters of described naked fine protection tube 10 are 0.3mm.
Inwall 13 diameters of naked fine protection tube 10 are 0.2mm.
The beneficial effects of the utility model:
Naked fine fuse unit of the present utility model is surface cover one deck protective casing outside to molten naked fibre, neither affects thermoplastic sleeve pipe hot melt and protects again naked fibre injury-free.After naked fine periphery adds the last layer protective casing; in 30 seconds of thermoplastic sleeve pipe heating; the heat of meeting hermetic section; protect naked fibre can not be burned; and strengthen intensity and the isolated property of naked fibre, like this, except the thermoplastic sleeve pipe; protective casing also carries out hard power protection to naked fibre, and fusion point is carried out second protection.The length controllability of the naked fine protection tube in the utility model is good, adapts to different optical cable and the optical fiber of multiple packing forms.For example for the heat molten type quick coupler of the usefulness of registering one's residence, the rubber-insulated wire of 2X3mm is to the hot melt of rubber-insulated wire, and the loosely shielded optical cable of 2.0/3.0mm is to molten, and the rubber-insulated wire of 2X3mm is to welding of the loosely shielded optical cable of 2.0/3.0mm etc.
Naked fibre has had protective casing in the naked fine fuse unit of the present utility model, can improve naked fibre to molten construction quality and efficient, guarantees the fixed of network.
For further specifying above-mentioned purpose of the present utility model, design feature and effect, below with reference to accompanying drawing the utility model is elaborated.
