Description
Technical field
Technical field of optical fiber communication is the utility model is related to, it is particularly a kind of for the double of heat molten type fiber active linker
Core fibre tempreature bulb.
Background technology
With the continuous development of optical communication technique, light entering and copper back, fiber to the home are widely used, and the joints of optical fibre are also wide
It is general applied among the continuing of optical fiber.When heat molten type fiber active linker heats, due to peelling off the light of external coating and protective layer
Fine very fragile, the protection to fibre junction point seems extremely important.Conventional hot melt pipe is mostly a pin at present, to fibre junction point
Protection insufficient strength it is big, be easily deformed, damage during the optical fiber of stripping hot melt, splicing point is easily broken off, and causes transmission loss inclined
Greatly, the transmission quality of fibre circuit is influenceed, or even causes the phenomenon of optical fiber Transmission, shortens the service life of optical fiber.
Utility model content
To solve above-mentioned problem, the purpose of this utility model is that providing a kind of heat molten type optical fibre that is used for connects
Connect the twin-core fiber tempreature bulb of device.The twin-core fiber tempreature bulb for heat molten type fiber active linker, can be to optical fiber
Continue position enhancing protection, support positioning, while avoids the problem of optical fiber joint flex deforms during external tube shrank, it is ensured that optical fiber passes
It is defeated smooth, increase the service life, reduce later maintenance cost, ensure steady signal transmission.
To reach above-mentioned purpose, the technical solution of the utility model is：
A kind of twin-core fiber tempreature bulb for heat molten type fiber active linker, including outer tube, inner tube and two draw points, institute
The cross section for stating outer tube is circle, and the cross section of inner tube is ellipse, and for outer tube sleeve outside inner tube, inner tube is inscribed within length with outer tube
Two end points of axle, the draw point is between outer tube and inner tube, and the short-axis direction along inner tube cross section is symmetrical arranged, draw point
It is and circumscribed with inner tube with outer tube inscribe.Outer tube and inner tube are nested, and two draw points are placed among outer tube and inner tube, are played
The effect of positioning is supported, strengthens the protection to fibre junction point, avoids what optical fiber joint flex during external tube shrank deformed from asking
Inscribe, extended fiber service life, reduce the maintenance cost in later stage.
Further, said inner tube is identical with the length of draw point, while the respectively less than length of outer tube.Outer tube is than inner tube and steel
Pin is swept along inner tube and draw point after slightly growing the two-port low-grade fever contraction so as to outer tube, further ensures that optical fiber transmission is smooth.
Further, a diameter of 1.4-1.6mm of the draw point.
Further, the draw point is made of 304 stainless steel materials.Material is 304 stainless steels, and hardness is high, stretching resistance
By force, be not easily broken, be corrosion-resistant, it is anti-get rusty, easy processing.
Further, said inner tube and outer tube are made of transparent material.Whether it is easy to the connection of detection fiber junction
Correctly, the damage of optical fiber in installation process is avoided.
Further, the outer tube material is crosslinked polyethylene.Crosslinked polyethylene has good heat resistance and insulating properties,
And minimum shrinkage temperature is 60 DEG C, contraction speed is fast, and efficiency of construction is high, applied widely.
The beneficial effects of the utility model are：
A kind of twin-core fiber tempreature bulb for heat molten type fiber active linker described in the utility model, can be to light
Fibre is continued, and position enhancing is protected, support positions, while avoids the problem of optical fiber joint flex deforms during external tube shrank, it is ensured that optical fiber
Transmit smooth, increase the service life, reduce later maintenance cost, ensure steady signal transmission.
