Description
Technical field
The utility model relates to the optical-fibre communications equipment technical field, is specifically related to GPZ.
Background technology
Along with the development of technology such as EPON, GPON, the large tracts of land of optical splitter is popularized and just have been determined that also the fiber cable network structure will be counted the optical cable point-to-point to putting the transformation that the tree-like little core of multiple spot is counted fiber cable network by big core from now on, and promptly network structure such as FTTH will become to take as the leading factor.This has also just caused the core number of terminal optical cable to significantly reduce.Yet the terminal devices such as GPZ that China adopts at present are many to serve as that increase and decrease adapter slot position, basis realizes that optical cable becomes the variation of end box core number with 12 cores, 24 core box bodies.Because box body volume, accessory etc. do not diminish, reduce thereupon, so cause the financial cost of termination box high.
Because the existence of fibre melting disc is arranged, cause that its box body need be thickeied, box body increases in the existing GPZ, and because GPZ manufacturer is numerous, the fibre melting disc model in the box is also more relatively, can't unify coupling.Existing GPZ, its loam cake separates with box body, needs with special screw fixed bin body, uses inconvenient.The fixed form of existing GPZ is single, and fixedly accommodation is narrower.
Summary of the invention
It is little that the technical problems to be solved in the utility model provides a kind of volume, the GPZ that price is low.
In order to solve the problems of the technologies described above, the technical solution of the utility model is:
A kind of GPZ; comprise box body and lid; box body comprises diapire; left side wall; right side wall; front side wall and rear wall; right side wall is provided with the introducing hole of passing for optical cable; the optical cable that stretches in the box body is fixed by optical cable fixation kit and diapire; the strengthening core of optical cable is fixed by strengthening core fixation kit and diapire; left side wall is provided with 2 or 4 adapters; the optical fiber of optical cable is connected with the tail optical fiber that has connector; optical fiber and tail optical fiber connecting portion overcoat pyrocondensation protection tube; connector is connected with adapter; the fiber spool that is made of 4 " Γ " shape members is set on the diapire; 4 " Γ " shape members are vertical to be fixed on the diapire and to be distributed on four end points of " ten " word; Γ " opening of shape member deviates from the center of diapire; and the center of diapire is provided with deck parallel by multi-disc and that the clamp of fixed interval on diapire constitutes, constitutes the draw-in groove of inlaying an overcoat pyrocondensation protection tube between adjacent two clamps, and unnecessary optical fiber and tail fiber disc are on fiber spool in the box body.
Above-mentioned GPZ, optical cable fixation kit comprise holder that is fixed on the diapire and the anchor ear that is seated on the holder, and anchor ear is fixed on the holder by gib screw.
Above-mentioned GPZ, the strengthening core fixation kit comprises the cylinder that is fixed on the diapire, has horizontal through hole and vertical threaded hole on the cylinder, strengthening core penetrates horizontal through hole and is fixed by the housing screw in the vertical threaded hole.
Above-mentioned GPZ, box body and lid are hinged and pass through snap lock.
Above-mentioned GPZ, introducing the hole is two, one of them is standby.
Above-mentioned GPZ embeds magnet in the box portion bottom wall.
Above-mentioned GPZ, magnet are two, distribute at two diagonal angles of diapire.
Above-mentioned GPZ, the length of box body * wide * height=16cm * 10.4cm * 2.4cm.
The utility model is 4 cores or 2 core GPZs, has reduced number of fitting parts, and the size of GPZ is corresponding to be reduced, and price reduces.Deck and fiber spool have been realized the function of original fibre melting disc, and be simple in structure, takies volume-diminished.It is little to the utlity model has volume, the advantage that cost is low.
