Description
Technical field
This utility model belongs to technical field of photo communication, and in particular to a kind of quick connector.
Background technology
Quick connector is a kind of attachment structure for causing the transmission of optical signal continuous-stable, but optical fiber enters traveling optical signal biography
When defeated, as the refractive index difference existed between different medium can cause optical signal that various different incidence angles are produced in optical fiber, cause
Make optical signal transmission unstable, optical signal transmission quality is affected.And, through-put power it is larger and need frequently plug or
The occasion of output optical fibre is changed, than if desired for medical laser equipment frequently changed using optical fiber etc., existing quick connector
There is an obvious shortcoming, optical fiber connection transmission is that two end faces can be broken by being in close contact coupling, extrusion friction repeatedly
The fineness of bad fiber end face, on fiber end face, the spot of contamination can also stop fiber optic conduction or cause fiber end face ablation accidentally
And cause coupling efficiency seriously to reduce.
Utility model content
For above-mentioned deficiency described in the prior, the purpose of this utility model is to provide one kind and is avoided that fiber end face
Abrasion, pollution and ablation, and steady signal transmission, the good quick connector of transmission quality.
To realize above-mentioned technical purpose, the technical scheme adopted by this utility model is as follows：
A kind of quick connector, including input pad, Transmission Part and output connector, are arranged in the input pad
There is optic fibre patchhole, the one end being connected with Transmission Part in input pad is provided with circular groove, the circular groove and light
Fine patchhole is communicated；Built-in fiber is provided with the Transmission Part, the built-in fiber includes fibre core and shell, and shell is wrapped in
On fibre core, and shell is provided with annular groove on the outer circumference surface of one end of input pad, fills in annular groove
There is optical medium；The output connector is provided with output socket.
The external diameter with diameter greater than optic fibre patchhole of the circular groove.Circular groove avoid the optical fiber of outside insertion with it is interior
Put the directly contact of fiber end face, it is to avoid abrasion, and the depth of circular groove is small so as to isolation fiber end face can be reached
Purpose will not seriously reduce coupling efficiency again.
External screw thread is provided with the outer circumference surface of the input pad.External screw thread is for being connected with outside optical fiber.
Refractive index of the refractive index of the optical medium more than shell.Being disposed to of optical medium preferably avoids optical signal
Loss so that when the optical signal of external fiber transmission is entered in annular groove, it is built-in through reflexing to for optical medium difference angle
Continue transmission in the fibre core of optical fiber, improve efficiency of transmission and transmission quality.
Thickness of the depth of the annular groove less than shell.
Female thread is provided with output socket.Output socket is for being connected with external equipment.
This utility model is connected with external fiber by the optic fibre patchhole of input pad, and circular groove is by exterior light
The transmission end face of fine end face and Transmission Part built-in fiber separates a small distance, it is to avoid directly contact, it is to avoid abrasion and pollute,
And the annular groove on the shell of built-in fiber cause external fiber transmission optical signal in the big optical signal of incident angle enter
When entering in annular groove, the fibre core relaying for being reflected back toward built-in fiber resumes defeated, improves efficiency of transmission and transmission quality.This reality
Simple, the low cost with new structure.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
As shown in figure 1, a kind of quick connector, including input pad 1, Transmission Part 2 and output connector 3.It is described defeated
External screw thread is provided with the outer circumference surface for entering connector 1.External screw thread is for being connected with outside optical fiber.And the input connection
Optic fibre patchhole 4 is provided with part 1, the one end being connected with Transmission Part 2 in input pad 1 is provided with circular groove 5, described
Circular groove 5 is communicated with optic fibre patchhole 4.The external diameter with diameter greater than optic fibre patchhole 4 of the circular groove 5.Circular groove
Avoid the optical fiber of outside insertion and the directly contact of built-in fiber end face, it is to avoid abrasion, and the depth of circular groove 5 be small,
Its purpose that can reach isolation fiber end face is made seriously to reduce coupling efficiency again.
Built-in fiber 6 is provided with the Transmission Part 2, the built-in fiber 6 includes fibre core 7 and shell 8, and shell 8 is wrapped up
On fibre core 7, and shell 8 is provided with annular groove 9 on the outer circumference surface of one end of input pad 1, and the annular is recessed
Thickness of the depth of groove 9 less than shell 8.Optical medium 10 is filled with annular groove 9.The refractive index of the optical medium 10 is more than
The refractive index of shell 8.Being disposed to of optical medium preferably avoids loss of optical signal so that the optical signal of external fiber transmission
During in annular groove, continue transmission in the fibre core for reflexing to built-in fiber of optical medium difference angle, improve biography
Defeated efficiency and transmission quality.
The output connector 3 is provided with output socket 11.Female thread is provided with output socket 11.Output socket is used
In being connected with external equipment.
External fiber bare fibre insertion input pad 1 optic fibre patchhole 4 in, and by circular groove 5 with it is built-in
The end face of optical fiber 6 is corresponding, is connected with external equipment by exporting the output socket 11 of connector 3, constitutes transmission channel.
