Abstract
A connector for a rapid fiber connector comprises two ceramic pins I (4) and II (2), a ceramic bushing (3) and an external injection-molded piece (1). After the two ceramic pins are inserted into the ceramic bushing (3), the external injection-molded piece (1) is wrapped. The connector for a rapid fiber connector is characterized in that zero-zero contact is realized after the two ceramic pins are butt-jointed. According to the utility model, the pins are effectively prevented from shedding after being butt-jointed, the pins can be more accurately positioned, the zero-zero contact of fibers is realized, the transmission of the fibers is more stable and reliable, the cost of a product is reduced, the promotion of fiber to the home is improved, and the concentricity of each fiber is guaranteed without position offset.
Description
Technical field
The utility model relates to fiber optic communication field, the connector of especially using about a kind of FC of being applied to type, SC type, ST type optical fiber quick connector.
Background technology
Optical fiber quick connector is the device that removably connects between optical fiber and the optical fiber; It is the accurate butt joint of two end faces of optical fiber; Go so that the luminous energy of launching fiber output is coupled to receive in the optical fiber to greatest extent, and make because it is got involved optical link and the influence that system causes is reduced to minimum, the basic demand of the joints of optical fibre here; To a certain extent, the joints of optical fibre have also influenced reliability and each item performance of optical transmission system.
The kind of at present known optical fiber quick connector has two kinds: cold joint formula and through type.The cold joint formula is to be connected with working of plastics with a ceramic contact pin, and a V-type groove is arranged in the working of plastics, and then covers with a working of plastics, with a locking member locking.Because V-type groove precision is at 0.125mm ± 0.001mm, require height to be easy to generate following problem, the V-type groove adds in injection moulding and is under pressure man-hour; Temperature, the influence of cool time etc., the contracting of the plastics of each batch than influence; Thereby scale error is bigger, and the working of plastics easy ageing, and serviceable life is not long; Close pressed fiber because the V groove location of plastic is two in addition, there is the slit centre, and matching fluid is overflowed easily; Cause original just uneven fiber end face surface of contact few, no matching fluid compensation, thus decay is big.Thereby give three nets and of China, Fiber to the home brings obstacle.The direct-pass type optical fiber quick coupler be in the work progress the contact pin top that directly penetrates into connector after the fiber cut, can't focus in the work progress, can't grind the contact pin end face; Thereby surface of contact is few when causing fiber alignment; Decay is big, and optical fiber is movable easily, poor stability.
No matter be that the cold joint formula or the major defect of direct-pass type optical fiber quick coupler are that V-type groove precision does not reach requirement, can't guarantee concentricity during fiber alignment, squinting easily in the position, causes transmission attenuation big.
The utility model content
To the problem of above existence, the purpose of the utility model is to provide a kind of fast fibre connector to use connector, is two contact pins are inserted sleeve pipe, makes two deviation control behind the contact pin fiber alignment within 0.002mm, guarantees the concentricity of two fiber alignments.
The technical scheme of the utility model realizes in the following manner: a kind of fast fibre connector is used connector; Comprise two ceramic contact pin I, II; A porcelain bushing, outside moulding is after inserting porcelain bushing with two ceramic contact pins; Outside moulding is enclosed in it wherein, it is characterized in that: be zero zero contact of bumping after described two ceramic contact pins butt joint.
Described ceramic contact pin I is the two that has penetrated optical fiber, grinds through muller and inserts in the porcelain bushing.
Described ceramic contact pin I and contact pin II are processed with groove outside porcelain bushing, so that injection moulding is fixed and guaranteed that two ceramic contact pins and porcelain bushing form integral body.
Described ceramic contact pin II is a gauge pin, insert in the porcelain bushing one with injection moulding in ceramic contact pin I is docked at porcelain bushing after form zero and bump zero the contact.
Described outside moulding is the transparent body.
Described ceramic contact pin I and ceramic contact pin II are zirconium oxide ceramic contact pin; Porcelain bushing is a zirconia ceramic sleeve.
The utility model inserts sleeve pipe with two contact pins, thereby guarantees two contact pin concentricitys and precision, and behind the assurance fiber alignment can not squint in the position; Fundamentally solved original problem, Optical Fiber Transmission is more stable, and is reliable; Connect the decay of back thereby reached industry standard,, effectively avoid coming off for after fiber-to-the-home popularization plays facilitation and can make the contact pin butt joint less than 0.3DB; And make the contact pin location more accurate, realize that zero of optical fiber bumps zero butt joint, for facilitation is played in fiber-to-the-home popularization; Concentricity when having guaranteed fiber alignment has solved because of squinting the position the big problem of consequent transmission attenuation easily.
