Description
Technical field
The utility model relates to the optical fiber interconnection technique.More particularly, the utility model relates to a kind of straightly-inserted preembedded optical fiber quick connector.
Background technology
When any fibre system is installed, all must consider optical fiber or optical cable to be connected with each other, to realize continuing of optical link with low-loss method.Continuing of optical fiber link can be divided into two kinds of nonvolatil and activity 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 the selectivity interworking between each flexible jumper.
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, being widely used in optical fiber transmission line, fibre distribution frame and test optical fiber instrument, the instrument, is 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 every 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, promptly the high-accuracy assembly of general employing of the Jue Daduoshuo 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 be divided for by factory and directly produces the traditional fiber flexible jumper finished and two kinds of the optical fiber quick connectors of manual quick Fabrication at the construction field (site), the former must use such as: muller in dust proof workshop, inhale equipment processing and 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, so the latter is beneficial to the working-yard at 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: optical fiber inserted in the quick coupler, backs down and enter 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 enters V-shaped groove the optical fiber front end to remove to push open two closed up and down V-shaped grooves, because it is limited by the thrust that optical fiber conducts, 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 be subjected to 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: (the ceramic insertion core front end is to the V-shaped groove centre position) is earlier pre-buried and fix an optical fiber in optical fiber quick connector inside, and in V-shaped groove, be pre-charged with optical fiber matching fluid, again treating that jointed fiber inserts optical fiber quick connector, contact with pre-buried optical fiber, at last two V-shaped grooves up and down are fixed two optical fiber, fill slit between two optical fiber, the connection of realization light path by 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, increased a fiber alignment face in the overall optical link, also just increased loss and the labile factor in the link.2, finish 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, the holding force that causes the less optical fiber of external diameter wherein to be subjected to 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.
