Description

A kind of eardrum formula can repeat to open the optical fiber connector of use

Technical field

The utility model relates to a kind of coupling arrangement that optical fiber is installed that is used for; Be sealed in V-type slot part in the lock pin assembly in the eardrum chamber; Thereby use the spring folder mode of holding tightly to drive the eardrum pressed fiber; And can repeat to open and use, be specifically related to preset optical fiber or the non-optical fiber connector that presets two kinds of continuation methods of optical fiber.

Background technology

At present, the Quick Connect Kit product that is used for repeating opening use mainly adopts three kinds of mode fixed fibers respectively.

First kind is to realize fiber alignment Cheng Duan's through two optic fibre ends of sheet metal secured in alignment that compress doubling; Second kind is to realize fiber alignment Cheng Duan's through compressing involutory unit of plastic fixed fiber; The third compresses V-block through case block formula gland rubbing and pressure slider pad and fixes optical fiber realization fiber alignment Cheng Duan.Wherein, in the V-block on the sheet metal of doubling, involutory unit of plastic or slider pad opposite, establish the V-type groove that is used for fiber alignment; Optic fibre end link position at the V-type groove splashes into fluent meterial to improve the translucidus of splicing point; Thereby the action of hold down gag be through the sheet metal of pressing doubling or involutory unit of plastic or rubbing and pressure slider pad reduce V-type line of rabbet joint crack compress aim at optical fiber realize two optical fiber to being connected into end.

In optical fiber fixing; In first kind of optical fiber fixed form, withdrawal of currency from circulation groove must be set during the sheet metal pressing on the opposite of V-type groove in the sheet metal secured in alignment mechanism, prevent the optical fiber pressure-off; The optical fiber clearance control guarantees aperture by the space of sheet metal in die cavity of amounting to; Be V-type groove gap (wearing fine gap), these have brought greatly manufacture difficulty, and yield rate is low; In second kind of optical fiber fixed form; Plastics V-block aligning guide is when locking optical fiber; Gland rotatably compresses the optical fiber in the V-type groove, owing to compress mode through rotation, receives the gap drift influence of gland; The optic fibre force direction usually can out of plumb V-type groove, and the error of optical fiber align precision brings two jointed fiber connecting losses to strengthen; The optical-fibre channel of plastics V-block aligning guide is when reusing; Need back down briquetting with private key, the aperture of backing down requires to need strict accuracy requirement, and the product lot quantity manufacture difficulty is big; Yield rate is low; And backing down fricative plastics debris contamination splicing point in the process, the logical light of influence causes connecting quality to descend during repeated use; The plastics V-block aligning guide initial state that has is a free state, need back down the V-block passage when optical fiber penetrates, and matching fluid absorption is arranged in it; When causing optical fiber to penetrate to back down the V-type groove; Wear fine resistance and strengthen, false butt joint probability improves in the engineering, and sharp in addition fiber cut end face is easy to the scratch V-block; Produce the debris contamination splicing point, cause the failure that continues; In the third optical fiber fixed form,, receiving when building lid and pressing down because slider pad is the design of threshold formula; Slider pad is because plastic deformation influences, and downward rubbing when rotating the pressure fibre makes the optical fiber in the V-type groove produce rubbing; Optic fibre force direction and V-type groove out of plumb are brought the alignment precision variation of jointed fiber, and connecting loss strengthens, because alignment precision receives the influence of material, cooperation interference precision; The alignment precision dispersion is big, causes the repetition poor performance of fibre junction.

The common shortcoming of preceding two kinds of optical fiber fixed forms is that the V-type slot part can not seal; Coupling storage chamber at night is not set, causes the matching fluid of the usefulness that is used in the V-type groove to continue to be polluted easily and runs off, directly influence and continue the life-span; Though the third can have certain sealing process at operating conditions; But can not seal before using, and the easy landing of gland of unlatching when reusing, receive the pollution of environment in the repeated use process easily.
