Abstract
The utility model provides an insulation optical fiber interface module, which comprises an isolator, a metal fixed base, a metal nut cap, a ceramic wafer, a ceramic bushing and a ceramic inserting core. The ceramic inserting core is inserted in the ceramic bushing, one end of the ceramic bushing is pressed in the metal nut cap through interference fit, the ceramic wafer penetrates through the ceramic inserting core, the other end of the ceramic bushing is pressed in the metal fixed base through interference fit, and the isolator is fixed in the metal fixed base through a gluing mode, and is align to one end of the ceramic inserting core pressed in the metal fixed base. The insulation optical fiber interface module increases anti-static capability of components, reduces return loss of light, reduces physical contact of and ceramic inserting core end face in an assembling process, thereby improving acceptability of assembly manufacture and reducing manufacture cost.
Description
Technical field
The utility model relates to the optical transmission connector spare in a kind of optical fiber communication, particularly relates to a kind of two-forty insulating optical fiber interface module.
Background technology
The optical fiber interface assembly is to be used for being connected of laser instrument and optical cable optical fiber, and it is the indispensable part of light transmission in the optical communication system, and the section of the optical fibre core that the optical fiber interface assembly will connect is aimed at, presses close to and can repeatedly be used repeatedly.Because the core diameter of optical fiber is thin (reaching nanoscale) very, the processing technology of optical fiber interface assembly and precision all have the higher requirement of ratio.Because the optical fiber interface assembly will weld together with generating laser when using, the static that is produced by generating laser like this will be delivered on the short contact pin assembly, thereby influences the stability of light transmission.
The utility model content
For solving the problems of the technologies described above, the purpose of the utility model is to provide a kind of insulating optical fiber interface module, increases the antistatic effect of setting up, and has reduced return loss.
For realizing above purpose, the utility model provides following technical scheme:
A kind of insulating optical fiber interface module; Comprise isolator, metal firm banking, metal nut cap, potsherd, porcelain bushing, ceramic insertion core; Said ceramic insertion core inserts in the porcelain bushing; Said porcelain bushing one end is pressed in the metal nut cap through interference fit, and said potsherd is through on the ceramic insertion core, and the other end of said ceramic insertion core is pressed in the metal firm banking through interference fit; Said isolator is fixed in the metal firm banking through adhesive means, and holds level with both hands neat with one of the ceramic insertion core that is pressed into the metal firm banking.
As a preferred version of the utility model, said ceramic insertion core adopts ends A PC oblique angle pattern.
As another preferred version of the utility model, said porcelain bushing is to have groove and the cross section opening porcelain bushing for " C " font on the total length.
As another preferred version of the utility model, said ceramic insertion core and porcelain bushing all adopt zirconium dioxide faience material to process.
The beneficial effect that the utility model brings is:
1, avoided leaving metal trace on the ceramic insertion core surface after the interference fit because of ceramic insertion core and component metals firm banking and external metallization firm banking, increased the antistatic effect of assembly;
2, through the use of design of both-end APC face rake angle and isolator, reduce Optical Return Loss, be applicable to the transmission of higher rate signal.
3, reduce the physics contact of ferrule endface in assembling process, thereby improved the qualification rate that assembly is made, reduced production cost.

Embodiment
Below in conjunction with accompanying drawing the preferred embodiment of the utility model is set forth in detail, thereby the protection domain of the utility model is made more explicit defining so that advantage of the utility model and characteristic can be easier to it will be appreciated by those skilled in the art that.
A kind of insulating optical fiber interface module as shown in Figure 1; Comprise isolator 1, metal firm banking 5, metal nut cap 6, potsherd 2, porcelain bushing 4, ceramic insertion core 3; It is characterized in that said ceramic insertion core 3 inserts in the porcelain bushing 4, said porcelain bushing 4 one ends are pressed in the metal nut cap 6 through interference fit; Said potsherd 2 is through on the ceramic insertion core 3; The other end of said ceramic insertion core 3 is pressed in the metal firm banking 5 through interference fit, and said isolator 1 is fixed in the metal firm banking 5 through adhesive means, and holds level with both hands neat with one of the ceramic insertion core 3 that is pressed into metal firm banking 5.Said ceramic insertion core 3 adopts ends A PC oblique angle pattern.Said porcelain bushing 4 is for having groove and the cross section opening porcelain bushing for " C " font on the total length.Said ceramic insertion core 3 and porcelain bushing 4 all adopt zirconium dioxide faience material to process.Wherein, The effect of isolator 1 is that direction of light is limited; Make light can only folk prescription to transmission, can well be isolated by optoisolator through the light of optical fiber echo reflection, improve light wave transmissions efficient; Reduced the influence of echo reflection, effectively raised the stability of output optical fibre laser instrument (LD).
The above; Be merely the embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any those of ordinary skill in the art are in the technical scope that the utility model disclosed, and variation or the replacement that can expect without creative work all should be encompassed within the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion with the protection domain that claims were limited.
