Description

The joints of optical fibre

Technical field

The utility model is related to a kind of connector, more particularly to a kind of joints of optical fibre.

Background technology

Receptacle（The joints of optical fibre）Can be widely applied to various TOSA/ROSA/BOSA laser assemblies, transmitting-receiving mould In the optical devices such as block, optical device interface, with boundless market prospects.The Receptacle of two-forty product is applied to, Requirement to product is higher, for example coupling efficiency.

Utility model content

Deficiency in the presence of for prior art, the utility model provide a kind of high joints of optical fibre of coupling efficiency.

For achieving the above object, the utility model employs following technical scheme：A kind of joints of optical fibre, including conduct First metalwork of housing, is sequentially provided with the second metalwork and ceramic ring as joint in first metalwork, and described the The oral area of two metalworks arranges the first lock pin, and first lock pin is provided with first through hole, second metalwork and ceramic ring The within the chamber being collectively forming arranges the second lock pin, arranges the second through hole, the first lock pin axis and pottery on second lock pin The angle of ceramic ring axis is α, and the inclination angle of first insertion core end face is β, first insertion core end face and ceramic ring end face angle For alpha+beta, the refractive index of n0 × sin β=sin (β+α), wherein n0 for optical fiber core diameter corresponding wavelength.

Preferably, first lock pin setting coaxial with first through hole.

Compared to prior art, the utility model has the advantages that：This joints of optical fibre can the first lock pin and Two lock pin angles are reasonable in design, so as to ensure that the coupling efficiency of product.

Description of the drawings

Fig. 1 is fibre-optic connector structure figure in the utility model.

Specific embodiment

Referring to Fig. 1, a kind of joints of optical fibre, including the first metalwork 5 as housing, in first metalwork 5 according to Sequence is provided with the second metalwork 2 and ceramic ring 4 as joint, and the oral area of second metalwork 2 arranges the first lock pin 1, First lock pin 1 is provided with first through hole, and second metalwork 2 and the within the chamber that ceramic ring 4 is collectively forming arrange the Two lock pins 3, arrange the second through hole on second lock pin 3,1 axis of the first lock pin is α with the angle of 4 axis of ceramic ring, The inclination angle of 1 end face of the first lock pin is β, and 1 end face of the first lock pin and 4 end face angle of ceramic ring are alpha+beta, n0 × sin β= Sin (β+α), wherein n0 are the refractive index of optical fiber core diameter corresponding wavelength, draw the value of α, β, you can ensure what insertion core end face was gone out Just horizontal, for example, α=2.8 degree, β=6 degree, n0=1.465；Or, α=3.7 degree, β=8 degree, n0=1.465.Described first inserts The setting coaxial with first through hole of core 1.

This joints of optical fibre can the first lock pin 1 reasonable in design with 3 angle of the second lock pin, so as to ensure that product coupling imitate Rate.

Finally illustrate, above example is only unrestricted in order to the technical solution of the utility model to be described, although ginseng The utility model is described in detail according to preferred embodiment, it will be understood by those within the art that, can be to this The technical scheme of utility model is modified or equivalent, the objective and model without deviating from technical solutions of the utility model Enclose, which all should be covered in the middle of right of the present utility model.
