Description
Technical field
The utility model relates to a kind of connector, and the covered wire cable that particularly relates in a kind of optical communication field is prefabricated into the end connector.
Background technology
Business development and the development in science and technology of in recent years optical communication industry and the popularization of correlation technique along with domestic three large operators, domestic FTTH Fiber to the home networking engineering is launched in succession on a large scale, become simultaneously the final pattern of recent Optical Access Network development, it not only adapts to the demand for development of optical arena engineering construction, also meets users to the high speed of optical network signal, jumbo transmission requirement.In FTTH access engineering, the mechanical bend performance of traditional conventional inside cable and tensile property can not satisfy FTTH access and house wiring requirement, and therefore low bending radius, high-intensity covered wire cable are widely applied among the FTTH.
In the covered wire cable of FTTH access engineering continues, the mode that rubber-insulated wire is fixed connector has solved quick coupler maintenance cost height, unstable properties, the high defective of breakdown maintenance rate, with its low cost, be easy to safeguard that constructability and steady performance become the preferred manner that FTTH access engineering covered wire cable continues gradually.
Existing covered wire cable is prefabricated into end and uses connector, comprises ferrule assembly, inner core, spring, ends cover and overcoat; Described ferrule assembly forms by ceramic insertion core and with metal caudal peduncle that the ceramic insertion core crimping is fixed together, and inner core and overcoat connect and fix, spring with end the cover face and contact support.The connector of this structure, because ferrule assembly is when connecting with covered wire cable, spring can produce axial screen resilience, the bare fibre resilience was crooked in the middle of ferrule assembly drove when resilience, and bare fibre is repeatedly very easily fractureing after the resilience bending continuously, cause fiber-optic signal to interrupt, thereby online optical communication is produced totally unfavorable impact.
Summary of the invention
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, provide a kind of when connecting bare fibre can resilience not crooked, and pulling-out force can reach 120N, can guarantee that the covered wire cable of optical communication stable performance is prefabricated into the end connector.
For solving the problems of the technologies described above, the utility model adopts a kind of like this covered wire cable to be prefabricated into end and uses connector, comprises ferrule assembly, inner core, spring, ends cover and overcoat; Described ferrule assembly is comprised of ceramic insertion core and the metal caudal peduncle that is connected with this ceramic insertion core crimping, described inner core and described overcoat connect and fix, described spring housing is contained on the described metal caudal peduncle, and the two ends of spring are respectively with an end of metal caudal peduncle and end cover and offset, the described cover that ends connects and fixes with described inner core, this connector also comprises an adapter sleeve with center pit, one end of this adapter sleeve is connected with described metal caudal peduncle interference fit, the other end links to each other with covered wire cable, and the stack shell of this adapter sleeve cooperates with the described gap of only overlapping.
In the utility model, an end of described adapter sleeve is provided with endoporus, and this adapter sleeve is connected with described metal caudal peduncle interference fit by described endoporus.
The stack shell of adapter sleeve of the present utility model and described gap of ending between the cover are preferably 0.2 millimeter.
After adopting such structure, when ferrule assembly and covered wire cable connect, the axial screen resilience that spring produces acts on the metal caudal peduncle and ends cover, because an end of adapter sleeve is connected with metal caudal peduncle interference fit, the other end links to each other with external cable, the stack shell of adapter sleeve with only overlap the gap and cooperate, therefore, the screen resilience that spring produces drives the simultaneously vertically motion of bare fibre of ferrule assembly and adapter sleeve and covered wire cable, thereby resilience flexural deformation can not occur because of the screen resilience effect that is not subject to spring in bare fibre, the bare fibre resilience was crooked in the middle of thereby the ferrule assembly that has thoroughly solved traditional structure drove when resilience, cause bare fibre to fracture easily, the technical matters that causes the optical fiber disablement signal to interrupt; In addition, the pulling-out force of the utility model bare fibre can reach 120N.
