Abstract
The utility model discloses an LC grooved ferrule which comprises a ferrule body and a metal flange. A through hole is arranged at the center of the ferrule body, a chamfer is arranged at the front end of the ferrule body, a first fillet is used for transition from the rear end of the ferrule body to the through hole, a second fillet is arranged at the edge of the rear end of the ferrule body, and the rear end of the ferrule body is provided with a bulge loop. The metal flange comprises a bolt which includes a channel in the middle, the front end of the bolt includes an extension portion matching the bulge loop, and an installation hole of the metal flange is internally provided with threads. The first fillet is arranged to prevent adverse influence caused by bump when the ferrule body is connected with the metal flange, the bulge loop is arranged to enable that the extension portion of the bolt and the matched ferrule are firmly fixed to the metal flange, and thus, tight connection can be ensured even if the ferrule is dismounted for multiple times.
Description
Technical field
The utility model relates to optical fiber interface component technical field, relates in particular to the shaped grooved ceramic insertion core of a kind of LC.
Background technology
Optical fiber ceramic lock pin, claims again ceramic ferrule.The right cylinder of precise centering in optical fiber connector plug, there is a micropore at center, as fixed fiber.It is a kind of by nano zircite (ZrO2) material through a series of formulas, the high precision special cermacis element that processes, its aperture, out of roundness error are 0.5 Jing.Made connector is fiber active linker detachable, classification, makes the connection of optical channel, conversion scheduling more flexible, can be for debugging and the maintenance of light way system.
Existing ceramic insertion core is generally all plugged on metal flange, connect and unreliable, at ceramic insertion core through not tight with being connected of metal flange after plug repeatedly.
Summary of the invention
The utility model, for deficiency of the prior art, provides the shaped grooved ceramic insertion core of a kind of LC, and this ceramic insertion core can more closely be connected with metal flange, after plug is repeatedly used, still can keep tight connection.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: the shaped grooved ceramic insertion core of a kind of LC, comprise lock pin body and metal flange, described lock pin body center is provided with through hole, described lock pin body front end is provided with chamfering, described lock pin body rear end and described through hole are by the first round-corner transition, described lock pin body back edge is provided with the second fillet, described lock pin body rear end is provided with bulge loop, described metal flange comprises that middle part has the bolt of passage, described bolt front end has the extension coordinating with described bulge loop, in the mounting hole of described metal flange, be provided with screw thread.The harmful effect that when the first fillet being set can preventing that lock pin body is connected with metal flange, collision brings, bulge loop is set and extension on bolt can be coordinated with it ceramic insertion core is firmly fixed on metal flange, adopt and connect in this way timely ceramic insertion core and repeatedly dismantle and still can guarantee to connect closely.
The utility model compared with prior art, there is following beneficial effect: collision brings can prevent that lock pin body is connected with metal flange time harmful effect that the utility model arranges the first fillet, bulge loop is set and extension on bolt can be coordinated with it ceramic insertion core is firmly fixed on metal flange, adopt and connect in this way timely ceramic insertion core and repeatedly dismantle and still can guarantee to connect closely.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the syndeton schematic diagram of the utility model and metal flange.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail: referring to Fig. 1 to Fig. 2, the shaped grooved ceramic insertion core of a kind of LC, comprise lock pin body 1, described lock pin body 1 center is provided with for plugging the through hole 2 of optical fiber, described lock pin body 1 front end is provided with chamfering 3, described lock pin body 1 rear end and described through hole 2 are by the first fillet 4 transition, and described lock pin body 1 back edge is provided with the second fillet 5, and described lock pin body 1 rear end is provided with bulge loop 6.The first fillet 4 is set and can prevents from when lock pin body 1 is connected with metal flange 7 colliding the harmful effect bringing, bulge loop 6 is set for being connected and fixed with metal flange 7, metal flange 7 is connected more closely reliable with ceramic insertion core.
Metal flange 7 comprises that middle part has the bolt 8 of passage 81, described bolt 8 front ends have the extension 82 coordinating with described bulge loop 6, in the mounting hole 9 of described metal flange 7, be provided with screw thread, when this ceramic insertion core is installed to metal flange 7, now ceramic insertion core is inserted in the mounting hole of metal flange 7, then bolt 8 is tightened on described mounting hole 9 through ceramic insertion core front end, fixing by coordinating ceramic insertion core and metal flange 7 of bulge loop 6 and extension 82, even if repeatedly dismantling, this connection ceramic insertion core still can keep the compactedness that connects between them.
