Description
Technical field
The present invention relates to the joints of optical fibre (lightpeak), particularly a kind of joints of optical fibre of the loss that reduces light transmission.
Background technology
The joints of optical fibre generally include shell and optical fiber. Optical fiber is coated by protection sleeve conventionally in case fractureed. Shell comprises integrated lens and optical fiber holding seat. That optical fiber holding seat is formed with is opposing with lens, for the receiving space of up-winding fiber and protection sleeve. Fiber alignment in lens and receiving space, coupling, thereby the loss that convergence of rays can be transmitted to reduce light to optical fiber. Shell uses mold injection molding to make conventionally, be to form receiving space, mould have shape corresponding with optical fiber shape enter son. But, on the one hand, enter sub-size less, be therefore difficult to realize precise positioning, on the other hand, when injection mo(u)lding, the injected plastics material of molten condition enters the huge impulsive force that die cavity can produce and causes being offset into son, therefore, tends to existence bias in various degree between receiving space and lens, cause the optical fiber in receiving space also to have eccentric situation in lens, increase the loss of light transmission. In addition, due to outside lens are exposed to, easily contaminated or scratch, this also can increase the loss of light transmission.
Summary of the invention
In view of this, be necessary to provide a kind of joints of optical fibre of the loss that reduces light transmission.
A kind of joints of optical fibre, it comprises the transparent outer cover and the lens fiber being contained in this blind hole that offer a blind hole. One end that this lens fiber stretches into this blind hole is formed with a Conical Lenses face, for assembling light through this transparent outer cover to this lens fiber.
So, can there is not the eccentricity issues between lens and optical fiber, and this Conical Lenses face is protected in this transparent outer cover, avoid polluting or scratching problem, therefore, can reduce the loss of light transmission.

Detailed description of the invention
Refer to Fig. 1-2, the joints of optical fibre 10 of preferred embodiments of the present invention, it comprises the transparent outer cover 100 and two lens fibers 200 that are contained in respectively in these two blind holes 110 that offer two blind holes 110. One end that this lens fiber 200 stretches into this blind hole 110 is formed with a Conical Lenses face 210, for assembling light through this transparent outer cover 100 to this lens fiber 200.
So, can there is not the eccentricity issues between lens and optical fiber, and this Conical Lenses face 210 is protected in this transparent outer cover 100, avoid polluting or scratching problem, therefore, can reduce the loss of light transmission.
Concrete, this transparent outer cover 100 is substantially rectangular, and comprises the rear end face 130 that a front end face 120 and and this front end face 120 are opposing. These two blind holes 110 are opened on this rear end face 130.
This lens fiber 200 comprises the clad 230 of a fiber cores 220 and coated this fiber cores 220. This lens fiber 200 stretches into one section of this fiber cores 220 of these blind hole 110 one end and exposes (not being coated by this clad 230) from this clad 230, and this Conical Lenses face 210 is formed in this fiber cores 220.
See also Fig. 3-5, this blind hole 110 is divided into one and is connected with this second segment 114 near this rear end face 130 and with the first paragraph 112 of this clad 230 sizes couplings, second segment 114 that is connected with this first paragraph 112 and mates with these fiber cores 220 sizes and one and for the 3rd section 116 of this Conical Lenses face 210 of breasting.
Concrete, the cross sectional dimensions of this first paragraph 112 equals or is slightly larger than the size of the outline of the cross section of this clad 230, the cross sectional dimensions of this second segment 114 equals or is slightly larger than the cross sectional dimensions of this fiber cores 220, the cross sectional dimensions of the 3rd section 116 is less than the cross sectional dimensions of this second segment 114, and the length of this second segment 114 is less than the length of this fiber cores 220 of exposing from this clad 230.
These Conical Lenses face 210 parts stretch into and are arranged in the 3rd section 116, so, can locate this Conical Lenses face 210.
Because light enters with the 3rd section of part that 116 positions are corresponding from this front end face 120, through after this transparent outer cover 100 from blind hole bottom surface 1162 outgoing of the 3rd section 116 to this Conical Lenses face 210, therefore this front end face 120 adopts minute surface (can adopt minute surface die to carry out moulding) with the 3rd section of part that 116 positions are corresponding and the blind hole bottom surface 1162 of the 3rd section 116, so, can further reduce the loss of light transmission.
This transparent outer cover 100 also comprises a side 140 that connects this front end face 120 and this rear end face 130. This transparent outer cover 100 also offers a groove 150 on this side 140. This groove 150 is communicated with the junction of this second segment 114 with this first paragraph 112 of these two blind holes 110. These joints of optical fibre 10 also comprise a locating piece 300 mating with these groove 150 sizes. This locating piece 300 offers two locating slots 320 towards the end face 310 of the groove floor 152 of this groove 150. Each locating slot 320 is for locating corresponding this lens fiber 200, it comprise one be that V-type, size are mated with this clad 230, are reverse V-shaped equally for locating the first locating slot 322 of this clad 230 and one, size is mated with this fiber cores 220, for locating the second locating slot 324 of this fiber cores 220. So, can further locate this lens fiber 200.
This transparent outer cover 100 also comprises that one from the extended adapter sleeve 160 of this front end face 120, this adapter sleeve 160 is for being socketed with the adapter sleeve 160 of another joints of optical fibre 10, this adapter sleeve 160 encloses this front end face 120 to part that should two blind holes 110, so can realize the physical connection of these two joints of optical fibre 10, also the light path between these two joints of optical fibre 10 (i.e. light path between two pairs of these lens fibers 200) can be protected interior, can also prevent that in addition the minute surface part that this front end face 120 is corresponding with the 3rd section of 116 position from being scratched, thereby further avoid the loss of light transmission.
The setting that is appreciated that this transparent outer cover 100 should make: the distance behind these transparent outer cover 100 location between every a pair of this lens fiber 200 equals this operating distance to lens fiber 200.
Be appreciated that, the number of this blind hole 110 is not limited to present embodiment, should be depending on the logarithm of this lens fiber 200 of these joints of optical fibre 10 required couplings, in other embodiments, a pair of this lens fiber 200 is coupled if only need, only need to arrange this blind hole 110, and if two pairs of these the above lens fibers 200 that need to be coupled need to arrange plural this blind hole 110. Be appreciated that no matter be how many these blind holes 110, this adapter sleeve 160 all should be protected the light path of this all these joints of optical fibre 10 lens fibers 200 interior.
In a word; those skilled in the art will be appreciated that; above embodiment is only for the present invention is described; and be not used as limitation of the invention; as long as within connotation scope of the present invention, within the appropriate change that above embodiment is done and variation all drop on the scope of protection of present invention.
