Abstract
The utility model relates to a micropipe tie-in used for the protection of a micro cable and belongs to the technology field of the optical fiber equipment. The utility model consists of an outer sleeve, a pipehead, a pipehead cassette, a spring ring, a gasket and a sealing ring. The pipehead is inserted into the pipehead cassette. The end part of the pipehead cassette coordinates closely with the end part of the pipehead to form a pipehead module. The pipehead module together with the gasket, the spring ring and the sealing ring are coaxially arranged in sequence at the end part of the frustum-shaped outer sleeve. The clipping edge at the end part of the pipehead is clipped at the end part of the outer sleeve, the clipping head at the end part of the spring on the cylinder wall of the pipehead cassette is clipped into the clipping hole on the pipe wall of the outer sleeve, and the sealing ring is clipped on the convex platform on the inner wall of the outer sleeve. The micropipe tie-in provided in the utility model has simple and reasonable structure, excellent sealing performance, strong shock resistance and corrosion resistance, and remains airtight under 18 atmospheric pressures. The utility model provides a safe and reliable tie-in for the manufacture and construction of micropipes, and prolongs the service life of the optical fiber inside the micropipe greatly.
Description
Technical field
The utility model relates to a kind of microtube joint that is used for micro cable protection, belongs 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 purpose of this utility model is to propose a kind of microtube joint that is used for micro cable protection, is the manufacturing of microtubule and the construction reliable joint of providing convenience.
The microtube joint that is used for micro cable protection that the utility model 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 utility model 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.
