Embodiment
Be described in further detail the utility model by reference to the accompanying drawings now, accompanying drawing is the schematic diagram simplified, and only basic structure of the present utility model is described in a schematic way, therefore it only shows the formation relevant with the utility model.
As Figure 1-5, the utility model is built-in for the Fiber connection dish 1 of cold joint optical fiber 8, and the centre of Fiber connection dish 1 is to fine plate 3, the both sides of fine plate 3 is being symmetrical arranged to the fine plate of pressure 5, fiber slide cutting knife 10, is wearing fine plate 4.After cable jacket stripping is good when cable connection, optical fiber 8 is exposed from Loose tube, at this moment as classic method, no longer carry out the stripping of outer protective sleeve to optical fiber 8 and coat, but directly the optical fiber 8 of band sheath is inserted from the wire hole 6 wearing fine plate 4 is interior, until insert motionless, after being plugged etc. whole optical fiber 8, press the tight fine button 12 worn on fine plate 4 and on the fine plate 5 of pressure, the optical fiber 8 of insertion is firmly fixed, after both sides are all plugged, press fiber slide cutting knife 10 ejector button 12 on both sides respectively, sliding cutting cutter 10 can slip over along sliding cutting cutter track 9 automatically fast, cut off optical fiber 8.Next sliding cutting cutter 10 and the fine plate 5 of pressure is taken away from Fiber connection dish 1, at this moment terminal pad just leaves and middle fine plate 4 is worn to fine plate 3 and both sides, transversely the fine plate 4 of wearing on both sides slowly promotes to center by track again, make the optical fiber 8 cut enter in the middle wire hole 6 to fine plate 3 both sides simultaneously, continue again inwardly to push away, (axial clinging force is provided with therebetween until wear fine plate 4 and be combined with fine plate 3, to ensure the pressure of two optical fiber 8 end faces), at this moment, the end face of two optical fiber 8 can dock the close centre of fine plate 3 ceramic insertion core 15, continuing of optical fiber 8 inside just completes.
Although the method that the optical fiber 8 that above-mentioned a kind of optical cable rapid-acting coupling box adopts continues also belongs to the method for cold joint, compared with traditional cold joint method being applied to FTTH, have very large difference, be mainly reflected in following some:
Traditional cold joint method operates for a pair optical fiber 8 substantially, is single slot, and this cold joint method is all optical fiber 8 of disposable operation two optical cables, and generally all between 12 core-48 cores, optical fiber 8 quantity of single operation is many, and the cable connection time is short.
Traditional cold connection needs the oversheath of optical fiber 8 and coat to remove, peel off into naked fibre, this cold joint method eliminates this link, has not only saved the time, and eliminating the possibility that naked fibre easily ruptures in operation, this advantage especially thermal welding is incomparable.
The cutting employing of connector box to optical fiber 8 is specifically designed to trapezoidal blade and carries out sliding cutting, detain when pressing sliding cutting button 12, brute spring 16 by sliding cutting cutter 10 along below orbit shot out, sliding cutting cutter 10 slips over below quick row's optical fiber 8 good from cloth, and optical fiber 8 is just cut disconnected.This method can cut out very smooth optical fiber 8 end face, and compared with typical circular cutting knife and cutting pen, cut quality has had very large raising, even has the effect after approximate grinding.
In ceramic insertion core 15 of the present utility model, two optical fiber 8 end face joints are designed with special little match play, namely hold matter hole 11, matching fluid is just filled in here, and the benefit done like this is the problem that can solve matching fluid loss, its principle strengthens capillary action further, in matching fluid being firmly locked in.
By above technical finesse, within the insertion loss that optical fiber 8 continues can being reduced to 0.1dB, be similar to the effect of thermal welding.
Finally, described Fiber connection dish 1 entirety is implanted in cable splice closure common at present and has just become a kind of optical cable rapid-acting coupling box, penetrating and still traditional method useless such as fixing and sealing of fixing, connector box of optical cable.Just substituted for its inner structure.Rapid-acting coupling box is hat type shape, it can be designed to horizontal or other shape equally.
Connecting time of the present utility model is short, and conventional connector box all adopts thermal welding to continue, and institute is consuming time about 2 hours, and connector box described in the utility model adopts the cold joint technology improved, within connecting time can being foreshortened to 15 points of kinds.
The cost that continues is low, and with having Conventional splice closures cable connection except the expense of connector box, welding expense is about about 30 yuan, every core, and for 24 cores, chieftain's induding material and tailoring about needs 1000 ~ 1300 yuan.Carry out cable connection with connector box described in the utility model, be exactly fee of material itself substantially, labour cost reduces greatly, and the expense of chieftain's induding material and tailoring, about about 300 ~ 700 yuan, can reduce by more than 50%.
The utility model is simple to operation, does not need special technician to operate, and common workmen all can complete operation with reference to the step of instructions.
The utility model can be used for optical cable repairing, the continuing of temporary project optical cable, the continuing of branch cable and terminal optic cable, and under these occasions, is that ordinary couplings box is incomparable.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above, but the utility model is not limited to above-described embodiment, in the ken that those of ordinary skill in the art possess, can also make a variety of changes under the prerequisite not departing from the utility model aim.
