Summary of the invention
The object of the present invention is to provide a kind of joints of optical fibre, cause making line to solve in prior art take the many problems of personnel because also needing a people hand-held optical cable during assembling holder.
In order to solve the problem, technical scheme of the present invention is:
A kind of joints of optical fibre, comprise housing and be connected to the holder of housing rear end by syndeton, holder comprises the seat body of elbow structure, described seat body has the horizontal routing hole extended along the longitudinal direction and the vertical routing hole tilting with horizontal routing hole or intersect vertically, the rear end of seat body is provided with lower end and extends to Wire channel in building on described seat body lower surface, horizontal routing hole is corresponding with before and after Wire channel in building, and Wire channel in building upper cover is equipped with cover plate.
Described syndeton comprises the syndeton Part I and syndeton Part II that are integrally formed at upper and lower both sides, described seat body front end, and syndeton Part I, syndeton Part II are connected with housing by barb, notch.
Described cover plate passes through elastic conjunction structure installment on described seat body.
The left and right sides hole wall of Wire channel in building is respectively arranged with the mounting groove extended along the longitudinal direction, and the left and right sides of cover plate is provided with the mounting ear corresponding with each mounting groove, and over-surplus fit structure comprises the upper and lower side channel wall of mounting groove and the upper and lower end face of mounting ear.
The lower end of seat body is provided with seat body screw thread, and the lower end of cover plate is provided with the cover plate screw thread forming whole circle screw thread together with seat body screw thread, and the arc length of seat body screw thread is greater than the arc length of cover plate screw thread, and seat body screw thread and cover plate screw thread are installed with pressure welding case.
Beneficial effect of the present invention is: of the present invention when making line, the end of optical cable passes through the front side of Wire channel in building by horizontal routing hole, because horizontal routing hole is corresponding with before and after Wire channel in building, therefore optical cable can be passed by horizontal routing hole through Wire channel in building easily, when assembling holder, operating personnel are hand-held seat body on the other hand, because horizontal routing hole plays certain maintenance position-limiting action to optical cable, therefore operating personnel do not need hand-held optical cable again, optical cable can well be layed in vertical routing hole through Wire channel in building, cover plate is mounted cover the assembling that just can complete holder on Wire channel in building by operating personnel with another hand, the assembling process of holder only needs operating personnel just can complete, the seat body of elbow structure can realize optical cable the outlet of bending in advance, therefore can reduce the actual of the joints of optical fibre to take up room.
Further, the syndeton Part I of syndeton and syndeton Part II between left and right every be integrally formed on seat body, do not need secondary to assemble, therefore the precision of syndeton be easy to ensure, reduce the assembly precision requirement to holder.
