Description
[technical field]
The utility model relates to a kind of optical communication class passive device, particularly a kind of optical fiber collimator of special construction.
[background technology]
Optical fiber collimator is the most frequently used to basic element in optical passive component, play irreplaceable effect in many applications, refer to Fig. 1, conventional optical fiber collimator is primarily of collimation lens 1 ', optical fiber head 2 ' (kapillary 3 '+optical fiber cable 4 ') and glass bushing 5 ' three part composition, with glue, collimation lens 1 ' and optical fiber head 2 ' are fixed among glass bushing 5 ', three parts form metastable light collimating structure jointly, glass bushing 5 ' plays wherein and is very importantly fixedly connected with effect, but bring some inevitable problems simultaneously, the existence of glass bushing 5 ' increases the volume of product, require to contradict with the trend of market miniaturization. in addition in the assembling process of collimating apparatus, because the space between glass bushing 5 ' and optical fiber head 2 ' needs to fill with glue, be easy to during adhesive curing produce glue sky or bubble in the region of filling, affect yield rate and the reliability of product, under some need the condition of applied at elevated temperature, very serious product failure may be caused.
[summary of the invention]
The technical problems to be solved in the utility model, be the optical fiber collimator that a kind of special construction is provided, it no longer needs glass bushing, also glass bushing and optical fiber head is no longer needed to bond, therefore, greatly reduce the volume of optical fiber collimator, and greatly reduce the glue consumption of product, substantially can solve the problem that product produces glue sky or bubble completely, the performance of product is increased dramatically.
The utility model is achieved in that
A kind of optical fiber collimator of special construction, comprise collimating lens, a kapillary and an optical fiber cable, one end of described kapillary is provided with an introducing port, the other end is provided with a cylindrical aperture, the bottom of described cylindrical aperture is provided with an export mouth, mutually through between described cylindrical aperture and export mouth, and mutually through by a passage between described introducing port and described export mouth, described collimation lens is located in cylindrical aperture, and described optical fiber cable runs through described introducing port, passage and export mouth.
Further, described introducing port and export mouth are flare openings, and described introducing port is greater than described export mouth.
Further, described collimation lens comprises C-lens lens and GRIN Lens.
The utility model has the advantage of:
Kapillary of the present utility model makes the design miniaturization more of product, greatly reduce the volume of optical fiber collimator, this kapillary ensure that the relative integraty of optical fiber collimator, decrease glue consumption and adhesive surface, substantially can eliminate glue sky and bubble completely, the more reliable performance of product, and add and man-hour the operation of the fixing of optical fiber cable and collimation lens assembling is merged, this considerably reduce the process time of product, the production efficiency of product is increased substantially, and cost declines to a great extent.
[accompanying drawing explanation]
The utility model is further described with reference to the accompanying drawings in conjunction with the embodiments.
Fig. 1 is the structural representation of prior art.
Fig. 2 is structural representation of the present utility model.
[embodiment]
Refer to shown in Fig. 2, embodiment of the present utility model is described in detail.
A kind of optical fiber collimator of special construction, comprise collimating lens 1, kapillary 2 and an optical fiber cable 3, one end of described kapillary 2 is provided with an introducing port 21, the other end is provided with a cylindrical aperture 22, the bottom of described cylindrical aperture 22 is provided with an export mouth 23, mutually through between described cylindrical aperture 22 and export mouth 23, and it is mutually through by a passage 24 between described introducing port 21 and described export mouth 23, described collimation lens 1 is located in cylindrical aperture 22, and described optical fiber cable 3 runs through described introducing port 21, passage 24 and export mouth 23.Described collimation lens 1 comprises band angled ramp cylindrical lens (C-Lens) and GRIN Lens (G-Lens).C-Lens structure is selected in Fig. 2.
In the present embodiment, described introducing port 21 and export mouth 23 are flare openings, and described introducing port 21 is greater than described export mouth 23, the importing of optical fiber cable 3 when it is convenient for assembly, the flare openings of export mouth 23 is used for holding the unnecessary glue amount may overflowed when assembling, prevent unnecessary glue stain from leading to light face to optical fiber cable 3, cause product failure, collimation lens 1 and optical fiber cable 3 are fixed by kapillary 2 by described optical fiber collimator.
Refer to Fig. 2, during optical fiber collimator assembling, first pre-fix the relative position of kapillary 2 and collimation lens 1, again by polished certain angle and the optical fiber cable 3 having plated film slowly insert from the introducing port 21 of kapillary 2, make optical fiber cable 3 lead to light end face and stretch out suitable length from export mouth 23, rotate optical fiber cable 3, make optical fiber cable 3 end face parallel with the tapered plane of collimation lens 1, and guarantee fiber end face now is just positioned at the near focal point of collimation lens 1 when designing, move around optical fiber, make the optical index that optical fiber collimator reaches required, now from introducing port 21 solidification glue 4 in right amount, solidification glue 4 is full of the pore of whole kapillary 2 by capillary action and flows out from export mouth 23, the flare openings that the glue that export mouth 23 overflows is exported mouth 23 holds, solation is stoped to lead to light face to optical fiber, ensure that the qualified assembling of product, so far master operation completes.The utility model makes the assembling that is fixing and collimation lens 1 of optical fiber cable 3 settle at one go, and the horn-like structure of export mouth 23 ensure that the feasibility of this technique simultaneously.
The utility model is compared with existing fiber collimating apparatus, completely eliminated the adverse effect of glass bushing in conventional collimator, make the design miniaturization more of product, kapillary of the present utility model ensure that the relative integraty of product, decrease glue consumption and adhesive surface, substantially glue sky and bubble can be eliminated completely, make the more reliable performance of product, add and man-hour the operation of the fixing of optical fiber cable and collimation lens assembling is merged, this considerably reduce the process time of product, the production efficiency of product is increased substantially, and cost declines to a great extent.
The above, be only the utility model preferred embodiment, therefore the scope that the utility model implements can not be limited according to this, the equivalence namely done according to the utility model the scope of the claims and description change with modify, all should still belong in scope that the utility model contains.
