Abstract
The invention relates to microtubule joint used to protect micro cable. It includes outer tube, tubing head, blocking seat, spring ring, filling ring, seal ring. The tubing head is inserted in the blocking seat of which ends are close fit to form tubing head assembly which is set at the end of the outer tube together with the filling ring, spring ring, seal ring. The edge of the tubing head end is blocked at the end of the outer tube. The anchor end on the blocking seat wall is blocked in the hole of the outer tube wall. The seal ring is set on its dummy club. The invention has the advantages of reasonable structure, good sealing property, strong impact resilience, corrosion proof, gas proof under 18 barometric pressures which can supply safe and reliable joint for microtubule manufacture and construction, greatly increase fiber-optic useful life.
Description
Technical field
The present invention relates to a kind of microtube joint that is used for micro cable protection, belong to the fiber optic cable plant technical field.
Background technology
The optical fiber that is used for communication engineering must be protected in its construction and use, therefore at first optical fiber will be placed little cable or optical cable.In recent years, the microtubule technology that develops rapidly of America and Europe impels the manufacturing of little cable, microtubule and construction all to make significant headway.Little cable than the protective layer material of conventional cable lack, cost is low, because of in batches one by one cloth be placed in the pipeline little cable core number of the initial stage that can reduce.According to market demand, can lay at any time and substitute optical fiber, avoided laying 8～10 years after the above optical fiber utilization factor of hundred cores just reach 30% shortcoming.
Little cable must guarantee the serviceable life at least 20 years, and little in the meantime cable function can not be degenerated.Owing in construction and use, be in outdoor environment, so little cable must possess the bad external environment condition of opposing, as the ability of influences such as sewage, sump oil, low temperature, corrosion.Therefore little cable must be placed microtubule, the two ends of microtubule must seal with the waterproof sealing cap.The microtube joint that does not also have a kind of not only easy to use but also superior performance in the market.
Summary of the invention
The objective of the invention is to propose a kind of microtube joint that is used for micro cable protection, be the manufacturing of microtubule and the construction reliable joint of providing convenience.
The microtube joint that is used for micro cable protection that the present invention proposes comprises outer tube, tube head, tube head deck, turn, packing ring and O-ring seal.The profile of outer tube is the two ends symmetry, and two ends are thicker cylindrical, and the centre is thinner truncated cone, and the inwall at outer tube two ends is provided with boss, and thicker part divides on the cylindrical tube wall and has hole clipping.One end of tube head has edge, and the other end has Ka Tai.The tube head deck is a cylindrical shape, and the cylinder periphery has been cut reed vertically, and an end of reed links to each other with cylindrical wall, and the other end of reed is provided with dop.Tube head is inserted in the tube head deck, the Ka Tai of the end of tube head deck and tube head end is in wringing fit, become a tube head assembly, this tube head assembly and packing ring, turn, the coaxial successively end that is installed in the truncated cone outer tube of O-ring seal ecto-entad, the edge of tube head end is stuck in the end of outer tube, the dop of tube head deck barrel upper reed plate end is stuck in the hole clipping of outer tube tube wall, and O-ring seal is stuck on the boss of outer sleeve inner wall.
The microtube joint that is used for micro cable protection that the present invention proposes; its advantage is simple and reasonable; make whole joint tighness good; impact resistance is strong; corrosion-resistant; air tight under 18 atmospheric pressure, for the manufacturing of microtubule, construction provide safe and reliable joint, and have improved greatly the serviceable life of optical fiber in the microtubule.
