Description
Technical field
The present invention relates to the optical fiber interconnection technique.More particularly, the present invention relates to a kind of straightly-inserted preembedded optical fiber quick connector and its implementation.
Background technology
When any fibre system is installed, all must consider to be connected with each other optical fiber or optical cable, to realize continuing of optical link with low-loss method.Continuing of optical fiber link can be divided into nonvolatil and activity two kinds again.Nonvolatil continuing adopts fused fiber splice method or optical fiber cold joint to realize mostly; Continuing of activity generally adopts flexible jumper to realize, can realize between each flexible jumper that selectivity joins mutually.
Fiber active linker; Be commonly called as articulation; Be commonly referred to as the joints of optical fibre; Be be used to connect two optical fiber or optical cable form the continuous light path can reusable passive device, be widely used in optical fiber transmission line, fibre distribution frame and test optical fiber instrument, the instrument, be the maximum optical passive component of present usage quantity.The joints of optical fibre are exactly the accurate butt joint of two end faces of optical fiber; So that being coupled to receive in the optical fiber to greatest extent, the luminous energy of launching fiber output goes; And make because it is got involved optical link and the influence that system causes is reduced to minimum, this is the basic demand of the joints of optical fibre.To a certain extent, the joints of optical fibre have also influenced reliability and each item performance of optical transmission system.
The performance of the joints of optical fibre at first is an optical property, will consider interchangeability, repeatability, tensile strength, temperature and the plug number of times etc. of the joints of optical fibre in addition.Joints of optical fibre kind is numerous, and structure is different.But canvass, the basic structure of various types of joints of optical fibre but is consistent, the high-accuracy assembly of general employing of promptly most joints of optical fibre (by two contact pins and a tube coupling totally three parts forms) aligning of realization optical fiber is connected.Fiber active linker is current to divide for two kinds of the optical fiber quick connectors of the traditional fiber flexible jumper accomplished by factory's Direct Production and manual quick Fabrication at the construction field (site); The former must use such as: muller in dust proof workshop, inhale apparatus processing manufacturings such as glue machine, fiber cut cutter and baking oven; Fabrication cycle was generally more than 30 minutes; The latter only uses fiber cut cutter and scissors manufacturing; Fabrication cycle is generally 2 minutes, thus the latter be beneficial to the working-yard in the optical cable and optical fibres termination quick Fabrication fiber active linker.
Direct insertion optical fiber quick connector being arranged and presets optical fiber quick connector of in the market common optical fiber quick coupler.
Direct insertion optical fiber quick connector realizes that principle is: inserts optical fiber in the quick coupler, backs down and get into V-shaped groove with the optical fiber front end, and through ceramic insertion core front end, V-shaped groove two clampings up and down, fixed fiber is made into fiber active linker again.Its shortcoming is to rely on when optical fiber gets into V-shaped groove the optical fiber front end to remove to push open two closed up and down V-shaped grooves; Because the thrust by optical fiber conducts is limited; Sometimes need repeated multiple times to remove to push open V-shaped groove up and down, very easily cause optical fiber front end end face to receive friction damage, the logical light quality of influence with fiber end face.(referring to Fig. 1)
The realization principle of presetting system optical fiber quick connector is: at the pre-buried and fixing optical fiber of optical fiber quick connector inner (the ceramic insertion core front end is to the V-shaped groove centre position) elder generation; And in V-shaped groove, be pre-charged with optical fiber matching fluid; Treating that jointed fiber inserts optical fiber quick connector, contact again with pre-buried optical fiber, at last about two V-shaped grooves be fixed two optical fiber; Fill slit between two optical fiber, the connection of realization light path through treating the optical fiber matching fluid in the middle of jointed fiber and the pre-buried optical fiber.Its shortcoming is: 1, owing to introduced a pre-buried optical fiber, in the overall optical link, increased a fiber alignment face, also just increased loss and the labile factor in the link.2, accomplish in the factory of quick coupler owing to pre-buried fibre; Waiting to connect optical fiber is provided by the working-yard; Cause two kinds of optical fiber variant on external diameter, manufacturer, model easily; But two kinds of optical fiber all rely on same V-shaped groove to clamp, and the holding force that causes the less optical fiber of external diameter wherein to receive easily is not enough, and there is defective in stability in use.And two kinds of optical fiber very likely are not same manufacturer production, and difference is perhaps also arranged on model, more can cause very big influence to logical light quality, cause optical link quality to descend.3, owing to adopted matching fluid to realize that pre-buried fibre is connected with optical fiber to be connect, after the matching fluid loss, pre-buried fibre and the logical light quality of waiting to connect between the optical fiber will decline to a great extent, and cause optical fiber quick connector to lack (referring to Fig. 2) serviceable life.
Summary of the invention
The technical matters that the present invention will solve is, overcomes deficiency of the prior art, and a kind of straightly-inserted preembedded optical fiber quick connector and its implementation are provided.
In order to solve the problems of the technologies described above, the present invention realizes through following technical scheme:
A kind of straightly-inserted preembedded optical fiber quick connector is provided; Comprise the ceramic insertion core that is positioned at the optical fiber quick connector front end; And the V-shaped groove that joins with ceramic insertion core; Have one section to preset optical fiber and be located at ceramic insertion core to V-shaped groove, the said optical fiber that presets is that activity is installed in ceramic insertion core and V-shaped groove inner.
Among the present invention, the said termination of optical fiber in V-shaped groove of presetting is positioned at the interval of V-shaped groove front end 1/3 place to its tail end.
The present invention also provides a kind of implementation method of aforementioned straightly-inserted preembedded optical fiber quick connector, comprising:
, install one section earlier and preset optical fiber to the V-shaped groove place at the inner ceramic insertion core of optical fiber quick connector;
Treating that the tail end of jointed fiber from optical fiber quick connector inserts, will preset optical fiber and from V-shaped groove, release gradually, break away from optical fiber quick connector fully up to presetting the front end face of optical fiber from ceramic insertion core;
V-shaped groove up and down two compress, realize treating the fixing of jointed fiber.
Among the present invention,, make and preset the termination of optical fiber in V-shaped groove, be positioned at the interval of V-shaped groove front end 1/3 place to its tail end installing when presetting optical fiber.
Beneficial effect of the present invention is:
Its advantage is:
1, through adopting direct insertion structure to make to treat the jointed fiber ceramic insertion core front end that goes directly, makes the end face quantity that continues that produces because of fibre junction reduce to minimum, at utmost reduced logical optical loss, avoided the number of drawbacks of traditional pre-buried optical fiber technology.
2, through the pre-buried optical fiber of employing activity, make and need not remove to push open two V-shaped grooves up and down by the state that V-shaped groove in use is in out all the time with the front end of treating jointed fiber, avoided treating that the jointed fiber front end is damaged, greatly improved logical light quality.
