Optical fiber squeezes situation, is easy to influence optical coupling effect, causes light loss to increase, existing LC optical fiber connectors repeat performance
It is not high.
Utility model content
In order to solve the above problem, the utility model provides a kind of by the way that the stay pipe promotion anti-extrusion ability of tail sleeve is arranged,
By the way that ceramic connecting piece is arranged, stay pipe is bolted in a kind of LC optical fiber company that its use repeatly effect is promoted in ceramic connecting piece
Connect device.
The technical solution of the utility model is as follows：
A kind of LC optical fiber connectors, including front housing, rear shell, ferrule assembly, spring, stay pipe and tail sleeve, the front housing and
Rear shell is mutually butted to form a hollow cavity, ferrule assembly by spring coaxial packaging in the hollow cavity, the rear shell packet
Plastic casing and the ceramic connecting piece for being fixed on plastic casing tail portion are included, ceramic connecting piece is equipped with external screw thread, and stay pipe is bolted in
In ceramic connecting piece, tail sleeve is sheathed on the outer rear enclosure of stay pipe and is fixed in ceramic connecting piece.
Preferably, the ceramic connecting piece includes smooth face and external screw thread, and externally threaded outer diameter is less than smooth face
Outer diameter, tail sleeve set are fixed on smooth face.
Preferably, the outer diameter of the stay pipe is less than the tail end internal diameter of tail sleeve.
The slotting core includes ceramic insertion core, stainless steel lock pin and plastic cement lock pin.
Preferably, the front housing is packaged with dust cap.
The beneficial effects of the utility model are as follows：
1, it is higher using ring to be applicable to wiring integrated level for the anti-extrusion ability that tail sleeve is promoted by the way that stay pipe is arranged
Border；
2, by the way that ceramic connecting piece is arranged in the tail portion of rear shell, stay pipe is bolted in ceramic connecting piece, coaxial packaging effect
Fruit is good, and product use repeatly effect is good, is conducive to extend the service life of optical fiber connector.
Description of the drawings
Below in conjunction with the accompanying drawings, by the way that specific embodiment of the present utility model is described in detail, the utility model will be made
Technical solution and other beneficial effects are apparent.
Fig. 1 is LC optical fiber connector decomposition texture schematic diagrams；
Fig. 2 is the structural schematic diagram of LC optical fiber connectors.
Main element symbol description：
1, dust cap；2, front housing；3, ferrule assembly；4, spring；5, rear shell；51, ceramic connecting piece；51w, external screw thread；6、

Specific implementation mode
Further to illustrate technological means and its effect that the utility model is taken, below in conjunction with the utility model
Preferred embodiment and its attached drawing are described in detail.
Please refer to Fig.1-2, a kind of LC optical fiber connectors, including front housing 2, rear shell 5, ferrule assembly 3, spring 4, stay pipe 6
With tail sleeve 7, the front housing 2 and rear shell 5 are mutually butted to form a hollow cavity, and ferrule assembly 3 is by 4 coaxial packaging of spring in this
In hollow cavity, the rear shell 5 includes plastic casing and the ceramic connecting piece 51 for being fixed on plastic casing tail portion, ceramic connecting piece
51 are equipped with external screw thread 51w, and stay pipe 6 is bolted in ceramic connecting piece 51, and stay pipe 6 tightly fits in 7 internal face of tail sleeve, tail sleeve 7
6 outer rear enclosure of stay pipe is fixed in ceramic connecting piece 51.
Specifically, the stay pipe 6 has mechanical support ability, it is preferable that stay pipe 6 uses rigid plastics or metal material
The material of matter is made.
Preferably, the ceramic connecting piece 51 includes smooth face and external screw thread 51w, and the outer diameter of external screw thread 51w is less than light
The outer diameter in sliding surface portion, 7 sets of tail sleeve are fixed on smooth face.Specifically, the maximum outside diameter of the external screw thread 51w is less than tail sleeve 7
The internal diameter of smooth face, when passing through external screw thread 51w sets to be fixed in smooth face to avoid tail sleeve 7.External screw thread 51w is to 7 inner wall of tail sleeve
Wear.More specifically, the outer diameter of the stay pipe 6 is less than the tail end internal diameter of tail sleeve 7.
The slotting core includes ceramic insertion core, stainless steel lock pin and plastic cement lock pin.
Preferably, the front housing 2 is packaged with dust cap 1, and the dust cap 1 is anti-for being played to the micropore of ferrule assembly 3
Dirt acts on.
The beneficial effects of the utility model are as follows：
1, it is higher using ring to be applicable to wiring integrated level for the anti-extrusion ability that tail sleeve 7 is promoted by the way that stay pipe 6 is arranged
