Description
Technical field
The present invention relates to a kind of plug-in type joints of optical fibre for fiber alignment, with the efficient and convenient and small volume of use
The characteristics of.
Background technology
Converter valve is the main composition unit of UHV transmission equipment, and IGCT is the core component of converter valve, and it determines
The through-current capability of converter valve is determined, desired system voltage has been can obtain by the way that multiple Thyristors are connected.Converter valve is controlled
System controls the work of converter valve by optical fiber.Optical fiber is connected between converter valve and control room, the IGCT of each converter valve
A receipts one are needed to use to send out two optical fiber, the main triggering for realizing IGCT of effect of optical fiber and returning for trigger signal are examined.The change of current
In valve control system, a converter valve, a converter valve is controlled to contain nearly 500 IGCTs, it is necessary near using a rack
1000 optical fiber are controlled, and a rack will accommodate 1000 joints of optical fibre, therefore miniaturization to the joints of optical fibre is carried
Requirement is gone out.The threaded structure in the existing joints of optical fibre mostly front end, when being connected with control rack control panel joint, passes through
The joints of optical fibre are fixed on control panel by rotation swivel nut, and this is accomplished by leaving enough spaces between the adjacent joints of optical fibre,
Ability easy disassembly, does not waste time and energy so using only inconvenience is installed, and whole cabinet and panel take up space greatly, optical fiber
The integrated level that connector is laid is low.
The content of the invention
The technical problems to be solved by the invention are that the deficiency existed for above-mentioned prior art provides a kind of plug-in type
The joints of optical fibre, it is not only easy to install and use, and small volume, simple and compact for structure.
The present invention is to solve the problems, such as that used technical scheme set forth above is：Including fiber stub, it is characterised in that
Described fiber stub rear end is connected with connecting seat, and the rear end of connecting seat couples with caudal peduncle, between connecting seat termination and caudal peduncle
It is provided with elastomeric sleeve.
By such scheme, described elastomeric sleeve includes spring and sliding sleeve, and described spring housing is loaded on connecting seat periphery, preceding
End terminates in connecting seat termination, and rear end terminates in the front end of sliding sleeve, and described sliding sleeve is set on caudal peduncle, and it is less that front end sets diameter
Hole shoulder and connecting seat periphery phase configuration.
By such scheme, the fiber stub is circular shaft shape, and center opens up through hole, and through-hole aperture is 125 ~ 1000 μm, is led to
Hole rear end sets big end taper hole outwardly, importing when being inserted for optical fiber.
By such scheme, described connecting seat is sleeve-like, and connecting seat front end sets the larger termination of external diameter, termination front end
Spliced eye with fiber stub phase configuration is set, and the rear end of connecting seat is closely linked to by interference fit with caudal peduncle front end, or logical
Screw thread is crossed to be closely linked to the screw of caudal peduncle front end.
By such scheme, described caudal peduncle is tubulose, and front end is provided with the hole shoulder that is relatively large in diameter or screw and is connected base rear end
It is closely linked.
By such scheme, described fiber stub through hole, connection block hole and caudal peduncle through hole coaxial line and it is front and rear connect, institute
The caudal peduncle through-hole aperture stated is more than fiber stub through hole more than connection block hole, connecting seat through-hole aperture.
It is installed on control panel by pressing mode when the present invention is used, the mating interface on control panel is diameter of bore etc.
In the sleeve 9 of fiber stub external diameter, fiber stub is inserted directly into sleeve, and sliding sleeve is pressed using pressing plate, by acting force of the spring,
Fiber stub is steadily connected in sleeve, and pressing plate can on demand design porous pressing, such as 16 hole pressing plate, 18 holes pressing
Plate；During installation, the joints of optical fibre are first inserted, place into pressing plate；During dismounting, pressing plate, then drawn optical fiber connector are first taken out.
Beneficial effects of the present invention are：1st, the connected mode of the joints of optical fibre is pluggable mode, simple and compact for structure, without
Attaching nut, radial space is small, therefore when laying, the spacing between connector is smaller, and intensive laying can be better achieved；2nd, by
The connection of device is attached in plug mode, dismounting can be quickly accomplished, improve the installation efficiency of the joints of optical fibre；3、
Setting elastomeric sleeve can be such that fiber stub is connected in sleeve all the time, improve the connection reliability of the joints of optical fibre.
Brief description of the drawings
Fig. 1 is the front view of one embodiment of the invention.
Fig. 2 is the main sectional view of one embodiment of the invention.
Specific implementation method:
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Including fiber stub 1, the fiber stub is circular shaft shape, and center opens up through hole, and through-hole aperture is 125 μm, through hole
Rear end sets big end taper hole outwardly, importing when being easy to the bare fibre 6 of coat to insert.Fiber stub rear end and connecting seat
2 are connected, and described connecting seat is sleeve-like, and connecting seat front end sets the larger termination of external diameter, and termination front end is set inserts with optical fiber
The spliced eye of core phase configuration, the rear end of connecting seat is closely linked to by interference fit with the front end of caudal peduncle 5, and described caudal peduncle is pipe
Shape, front end is provided with the hole shoulder being relatively large in diameter and is closely linked to base rear end is connected.Fiber stub through hole, connection block hole and caudal peduncle are logical
Hole coaxial line and front and rear connection, are coaxial aperture, and described caudal peduncle through-hole aperture is more than connection block hole, and connecting seat through-hole aperture is big
In fiber stub through hole.Elastomeric sleeve is provided between connecting seat termination and caudal peduncle, described elastomeric sleeve includes the He of spring 3
Sliding sleeve 4, described spring housing is loaded on connecting seat periphery, and front end terminates in connecting seat termination, and rear end terminates in the front end of sliding sleeve, described
Sliding sleeve is set on caudal peduncle periphery, and front end sets hole shoulder and connecting seat periphery phase configuration of the diameter less than caudal peduncle external diameter, and sliding sleeve can
Axially move back and forth along connecting seat, by spring effect in connecting seat, fiber stub is produced top power forward.
The installation process of optical fiber is when the present invention is used：First the sheath of optical cable 8 is removed, exposes optical fiber 7, the front end of optical fiber 7
Removal coat, exposes one section of bare fibre 6, bare fibre length 1 ~ 10mm more long than lock pin length.The optical cable 8 that will be handled well is from connection
Device caudal peduncle end is put into, and by connecting seat, the bare fibre insertion fiber stub of leading portion is appeared from fiber stub front end.Then by glue
Injected in space of the water between the sheath of optical cable 8 and caudal peduncle, wait glue curing, after solidification, cut off optical fiber using diamant and insert
The bare fibre of core exposed portion, the grinding that carries out removing photoresist according to this to fiber stub end face, 9 μm of sand paper grindings, 3 μm of sand paper grindings, 1 μm
