Description
Technical field
The present invention relates to a kind of built-in type optical fiber Quick Connect Kit, can be at the scene that needs the optical fiber active link, the aligning of realizing optical fiber quickly and easily be connected, belong to the technical field that fiber optic telecommunications equipment is made.
Background technology
In optical access network, need a large amount of flexible jumpers that use.Therefore, need a kind of optical fiber splicing device fast and effectively, realize the connection of optical fiber.Very flexible is used in non-built-in type optical fiber splicing device operation inconvenience.Existing built-in type optical fiber splicing device needs the alignment device of additional structure complexity more, makes cost improve.Therefore, need a kind of simple in structure, cheap, on-the-spot optical fiber Quick Connect Kit of simple and easy fast, the suitable various optical fiber flexible connections of operation.
Summary of the invention
Technical matters: the purpose of this invention is to provide a kind of optical fiber that is applicable to and connect engineering site, low, the simple to operate quick and little optical fiber align coupling arrangement of insertion loss of device cost.
Technical scheme: built-in type optical fiber Quick Connect Kit of the present invention comprises wheel shank, pre-buried optical fiber, normal pore size lock pin and sleeve pipe; Pre-buried optical fiber is arranged in the normal pore size lock pin, and an end of normal pore size lock pin passes wheel shank and is arranged in sleeve pipe; Sleeve pipe and wheel shank join, and there is an opening at lock pin middle part in normal pore size to endoporus, and optical fiber to be connected joins in opening by sleeve pipe and pre-buried optical fiber.
In described opening, be filled with matching fluid in the junction of pre-buried optical fiber and optical fiber to be connected.
In described sleeve pipe, be provided with conical targeting port, be used to guide optical fiber to be connected to enter the normal pore size lock pin; Make optical fiber to be connected in pipe, be little curved state, lock and protect optical fiber to be connected.
Beneficial effect: the present invention compared with prior art, its remarkable advantage is: adopt the normal pore size lock pin, reduced the component processing accuracy requirement, low cost of manufacture; Optical fiber reaches accurate aligning with the lock pin aperture precision, and the operator can observe and complete operation by opening in use, has improved the accuracy of operation; Exhaust when opening is convenient to matching fluid injection and optical fiber to be connected insertion.Therefore, the present invention is simple in structure, cheap, easy and simple to handle fast.Be fit to various optical fiber and flexibly connect the scene, improve the matching degree of waiting to connect optical fiber, effectively reduce joint and insert loss, improve return loss.

Embodiment
Built-in type optical fiber Quick Connect Kit of the present invention comprises a wheel shank and pre-buried optical fiber.Described wheel shank is mainly the normal pore size lock pin, and an opening is arranged on the lock pin, and an end is provided with conical targeting port, is convenient to the insertion of optical fiber to be connected.When practical, opening part has matching fluid; The abutment of optical fiber to be connected and pre-buried optical fiber is positioned at the opening part of wheel shank; Sleeve pipe holding tube inner fiber when locking is waited to connect optical fiber is little curved, keeps in touch to guarantee pre-buried optical fiber and fiber end face to be connect.
This device comprises a wheel shank 1, pre-buried optical fiber 2, normal pore size lock pin 5 and sleeve pipe 6.One opening 3 is arranged on the described lock pin 5, make things convenient for matching fluid 8 be equipped with into.The one end is provided with conical targeting port 4; Described pre-buried optical fiber 2 is purchased in lock pin 5, and these pre-buried optical fiber 2 one ends place opening 3 places of lock pin 5, is used for and waits that connecing optical fiber 7 docks, and the other end places end, lock pin 5 outer end, and end face is standby behind rubbing down; The interior of described sleeve pipe 6 waits to connect optical fiber 7 diameters through being slightly larger than, and leaves the space and guarantees that waiting to connect optical fiber 7 is little curved state in sleeve pipe 6, and sleeve pipe 6 one ends tighten up the parts locking by the outside and wait to connect optical fiber 7.
One end of optical fiber 7 to be connected guides to opening 3 places of lock pin 5 by sleeve pipe 6 through the taper targeting port 4 of lock pin 5, and the operator can observe the fiber alignment processes by lock pin 5 and the opening 3 on the sleeve pipe 6.Exhaust when in addition, opening 3 also can be used as the optical fiber insertion; The pre-buried optical fiber of the accuracy guarantee of lock pin 5 internal diameters 2 and wait to connect optical fiber 7 and accurately aims at plays in connection procedure and locatees and alignment effect.Cooperate matching fluid 8 simultaneously, guarantee the low junction loss and the high reflection loss of fiber alignment; Sleeve pipe 6 is used for that guiding waits to connect optical fiber 7, to guarantee to wait to connect optical fiber 7 little curved and tighten up protection and wait to connect optical fiber 7; Use standard lock pin 5 is convenient to optical fiber and is connected, and improves the dirigibility that optical fiber connects.
The example that is connected to general single mode fiber: the lock pin product that this installs used lock pin 5 is the standard aperture.One end has the structure of conical targeting port 4, opening 3, and a section single-mould fiber is inserted in the lock pin 5 in advance as pre-buried optical fiber 2, and this optical fiber one end end face is positioned at opening 3 places, and the other end is to lock pin 5 outer end end faces, and this end face grinds on demand and is used for external connection.Be equipped with into matching fluid 8 in the lock pin 5.With external force optical fiber 7 to be connected is pushed lock pin 5 to opening 3 from sleeve pipe 6 through the targeting port 4 of lock pin 5, and maintenance thrust, it is little curved that optical fiber 7 to be connected is formed in sleeve pipe 6, by the latch mechanism optical fiber 7 to be connected that locks, guarantees that with this optical fiber 7 to be connected contacts with the end face of pre-buried optical fiber 2 simultaneously.At last, add encapsulation such as sheath external member at device and form the standard actions connector plug.
