Deep sea optical cable coupling box takes following scheme to realize:
The deep sea optical cable coupling box structure comprises bending restrictor, outer cylinder body, outer cone seat, the outer axis of cone, inner cone gland, the interior axis of cone, load nut, fiber storage tray, inner barrel, prefabricated tube, the injection moulding seal of being with universal joint.
Fiber storage tray is by being threaded in the middle of the load nut; The interior axis of cone and inner cone gland are formed the inner steel wire stationary installation, are connected with the load nut; Inner barrel is enclosed within on the two load nuts; Prefabricated jacket casing is connected with the deep-sea cable cable core by the injection moulding seal on inner barrel; Outer cylinder body is enclosed within outside the injection molding body, and the outer cone seat and the outer axis of cone are formed the outer steel wire stationary installation, are connected with outer cylinder body by outer cylinder screw cap; Bending restrictor is connected with outer cylinder screw cap.
The connection technology of deep sea optical cable coupling box is achieved in that
1. the connection of armour stationary installation in the deep-sea cable: the interior axis of cone is penetrated stainless-steel tube cable core precession inner cone gland, then the inner cone gland is placed on to withhold in the device and clamps.
2. the connection of optical fiber fiber storage tray: with the load nut interior armour stationary installation is installed in the two ends of fiber storage tray, opens and denude fine stainless-steel tube, draw optical fiber, carry out fibre junction; With the fiber reel that connects in fiber storage tray.
3. inner barrel is enclosed within on the load nut, prefabricated jacket casing is on inner barrel.
4. injection moulding sealing: the prefabricated tube that will install is put injection mould into, carries out the injection moulding sealing with injection machine, and injection moulding finishes injection molding body is put into the x-ray detection instrument, and the defective of injection moulding is checked.
5. outer cylinder body is moved on on the injection moulding seal,, with outer cone seat, outer steel wire, outer cone axis clamping, form the outer steel wire stationary installation with the hydraulic clamp instrument with outer axis of cone fixed outer cylinder body two ends.
6. with outer cylinder screw cap the outer steel wire stationary installation is connected with outer cylinder body, bending restrictor is fixed on the outer cylinder screw cap.
Deep sea optical cable coupling box is reasonable in design, simple in structure, volume is little, sealing property height, reliable.Big length submarine optical fiber cable transportation, lay and operational process in, it is unavoidable breaking down, so deep sea optical cable coupling box is an important coupling arrangement of repairing fault, the connection technology of deep sea optical cable coupling box is the reparation fault deep-sea cable optimum process method that continues.Under the hydraulic condition of 80MPa (suitable and 8000m), the waterproof seal of connector box had reliable waterproof sealing performance during 25 years; Afloat installation time was controlled in 12 hours; Pull-off strength is not less than 90% of optical cable Fracture Force, and the work pulling strengrth is not less than optical cable short-term job pulling force; Insulation resistance is not less than 1000M Ω (DC500V), and proof voltage intensity is not less than 5000V (DC/3min), need satisfy the electrically conducting performance simultaneously, guarantees remote power feeding; The fibre junction decay is not more than 0.06dB.
