Description
Technical field
The utility model relates to a kind of optical fiber splicing device, relates in particular to a kind of LC type short-tail without the heat-shrink tube fiber active linker.
Background technology
The joints of optical fibre, optical fiber with optical fiber between carry out the device that detachable (activity) is connected, it gets up the accurate docking of two end faces of optical fiber, so that the luminous energy of launching fiber output can be coupled to receive in optical fiber to greatest extent, go, and make because it is got involved optical link and the impact that system causes is reduced to minimum.Under some specific environment, as limited as spatial area, 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 can't 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 the 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, the optical fiber inner sheath is slidably arranged in disposal area by the elastic force of spring, the optical fiber inner sheath is from stretching out the front end of fore shell in disposal area, its complex structure, manufacturing cost is high, easily come off, install and use inconvenience.
The utility model content
The purpose of this utility model be to provide a kind of simple in structure, take up room littlely, easy to install, and can prevent effectively that the LC come off type short-tail is without the heat-shrink tube fiber active linker.
In order to solve the problems of the technologies described above, the technical scheme that the utility model is taked is as follows:
A kind of LC type short-tail is without the heat-shrink tube fiber active linker, comprise lock pin, web member, spring, the tail cover, shell and optical cable bare fibre, the web member head end is connected with shell, the web member tail end is connected with the tail cover, shell and web member form cavity, spring and lock pin are placed in cavity, optical cable bare fibre one end is fixed in lock pin, the other end passes cavity, it also comprises crimp rings, described web member tail end is provided with riveting spare, described crimp rings is located on web member tail end riveting spare, the crimp rings overcoat has the 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 the heat-shrink tube fiber active linker, and its described web member is provided with buckle, and shell passes lock pin and is stuck on buckle.
Above-mentioned LC type short-tail is without the heat-shrink tube fiber active linker, and its described web member inwall is provided with boss, and spring is arranged on the boss of web member inwall.
Above-mentioned LC type short-tail is without the heat-shrink tube fiber active linker, and its optical cable bare fibre uses glue curing in lock pin.
Above-mentioned LC type short-tail is without the heat-shrink tube fiber active linker, and it also comprises dust cap, and the dust cap shutoff is in the outer end of shell.
Beneficial effect:
The utility model has adopted technique scheme, it is provided with crimp rings, and crimp rings is protected optical cable outward and aramid fiber is pressed on web member afterbody riveting spare, and outer cover has the tail cover, described tail cover is the cylindrical shape of a hollow, one end outside surface inwardly shrinks, and takes up room little, and web member is provided with buckle, shell passes lock pin and is stuck on buckle, simple in structure, use, easy for installation, effectively avoided the generation of obscission.During use, tail cover, crimp rings, web member, spring are penetrated to 2.0 optical cables in order successively.Bare fibre is penetrated in lock pin, together with spring, shift web member onto the plug core tail handle bottom, then shell is penetrated and blocks web member buckle seat and fix from the lock pin head, then by crimp rings, optical cable is protected outward and aramid fiber is pressed on web member afterbody riveting spare, finally the tail cover is shifted onto on web member afterbody crimp rings crimping position and got final product, simple to operation.Add dust cap, prevent that lock pin is infected with dust,
