Description
Technical field
The present invention relates to a kind of optical fiber splicing device, particularly relate to a kind of LC type short-tail without heat-shrink tube fiber active linker.
Background technology
The joints of optical fibre, between optical fiber with optical fiber, carry out the device that detachable (activity) be connected, it gets up the docking of two of optical fiber end face precisions, the luminous energy exported to make launching fiber can be coupled to greatest extent to receive in optical fiber and go, and makes get involved optical link due to it and reduce to minimum to the impact that system causes.Under some specific environment, as spatial area is limited, or the environment such as the integrated higher wiring space of optical fiber distribution cabinet is little, may cause with common LC type fiber active linker that ODF cabinet door cannot be closed, long tail pipe extruding optical fiber increases the problems such as loss.Chinese patent ZL200920053030.3 discloses a kind of LC plastic joints of optical fibre and LC plastic joints of optical fibre duplex group, comprise fore shell, back cover, optical fiber inner sheath,
Spring, spring housing is located on optical fiber inner sheath, fore shell rear end and the socket of back cover front end, fore shell and back cover socket place offer disposal area, and optical fiber inner sheath is slidably arranged in disposal area by the elastic force of spring, and optical fiber inner sheath stretches out the front end of fore shell in disposal area, its complex structure, manufacturing cost is high, easily comes off, and installs and uses inconvenience.
Summary of the invention
The object of the present invention is to provide a kind of structure simple, take up room little, easy to install, and can effectively prevent the LC type short-tail come off without heat-shrink tube fiber active linker.
In order to solve the problems of the technologies described above, the technical scheme that the present invention takes is as follows:
A kind of LC type short-tail is without heat-shrink tube fiber active linker, comprise lock pin, web member, spring, tail cover, shell and optical cable bare fibre, web member head end is connected with shell, web member tail end overlaps with tail and is connected, shell and web member form cavity, spring and lock pin are placed in cavity, lock pin is fixed in optical cable bare fibre one end, the other end is through cavity, it also comprises crimp rings, described web member tail end is provided with riveting part, described crimp rings is located on web member tail end riveting part, crimp rings overcoat has tail cover, described tail cover is the cylindrical shape of a hollow, one end outside surface inwardly shrinks.
Above-mentioned LC type short-tail is without heat-shrink tube fiber active linker, and the web member described in it is provided with buckle,
Shell is stuck on buckle through lock pin.
Above-mentioned LC type short-tail is without heat-shrink tube fiber active linker, and the web member inwall described in it is provided with boss, and spring is arranged on the boss of web member inwall.
Above-mentioned LC type short-tail is without heat-shrink tube fiber active linker, and its optical cable bare fibre glue curing is in lock pin.
Above-mentioned LC type short-tail is without heat-shrink tube fiber active linker, and it also comprises dust cap, and dust cap shutoff is in the outer end of shell.
Beneficial effect:
Present invention employs technique scheme, it is provided with crimp rings, and crimp rings will to be protected outside optical cable and aramid fiber is pressed on web member afterbody riveting part, and outer cover has tail cover, described tail cover is the cylindrical shape of a hollow, one end outside surface inwardly shrinks, and take up room little, web member is provided with buckle, shell is stuck on buckle through lock pin, structure is simple, uses, easy for installation, effectively avoids the generation of obscission.During use, tail cover, crimp rings, web member, spring are penetrated 2.0 optical cables in order successively.Bare fibre is penetrated in lock pin, web member is shifted onto bottom plug core tail handle together with spring, then shell is penetrated from lock pin head and block web member buckle seat and fix, then will to protect outside optical cable and aramid fiber is pressed on web member afterbody riveting part by crimp rings, finally tail cover is shifted onto on web member afterbody crimp rings crimping position, simple to operation.Add dust cap, prevent lock pin to be infected with dust,
Accompanying drawing explanation
