Deep sea optical cable coupling box and connecting process thereof

Abstract

The invention provides a deep sea optic cable connector box and a connecting technique, which relates to a deep sea optic cable connecting device and the connecting technique, which is applicable to a factory connecting in a deep sea optic cable communication system, and also applicable to a fault repair of the deep sea optic cable. The structure comprises a bending limiter with a gimbal joint, an outer cylinder, an outer cone seat, an outer cone axis, an inner cone pressure cover, an inner cone axis, a bearing nut, a fiber storage disk, an inner cylinder, a prefabricated cylinder, a plastic injection airproof body; the fiber storage disk is connected with the middle of the bearing nut through a screw thread; the inner cone axis and the inner cone pressure cover constitute an inner jacket steel wire fixation device, which is connected with the bearing nut; the inner cylinder is sleeved on two bearing nuts; the prefabricated cylinder is covered on the inner cylinder, and connected with the deep sea optic cable core through the plastic injection airproof body; the outer cylinder is sleeved on the plastic injection body, the outer cone seat and the outer cone axis constitute an outer jacket steel wire fixation device, which is connected with the outer cylinder through an outer cylinder screw cap; the bending limiter is connected with the outer cylinder screw cap.

Description

technical field [0001] The invention relates to a deep-sea optical cable joint box and its connecting process, which relates to a deep-sea optical cable connecting device and its connecting process, which is suitable for splicing in factories in deep-sea optical cable communication systems, and also suitable for maintenance of deep-sea optical cable failures. Background technique [0002] At present, the submarine cable joint box can only withstand the water pressure of 500m, which is suitable for the connection of shallow sea optical cables, but the structure of the current deep sea optical cables is different from that of shallow sea optical cables, and deep sea optical cables are suitable for 8000m water depth, and the sealing performance requirements are higher, so The original submarine cable splice box cannot meet the connection of deep-sea optical cables, so a deep-sea optical cable splice box is needed to complete the connection of deep-sea optical cables. In additio...
