Description
Technical field
This utility model belongs to field of cable technology, especially relates to a kind of communication cable.
Background technology
Along with the high speed development of optical communication technique, backbone network and the interoffice trunk of China's wire net have commonly used optical cable, and optical fiber enters Access Network has become inexorable trend.But fiber cable laying expense is too high, joint expense and terminal optical-electronic conversion charges are expensive, therefore, in a very long time before light fibrillation is universal, the subscribers feeder of Access Network will based on metal cables, and metal cables mainly includes all-plastic cable, coaxial cable and data cable three kinds.
It is support shielding by support bar that existing cable has the disadvantage that between insulating barrier and conductor, and this insulated wire cores exists transmission jitter, and the anti-tampering property of these communication cables existing is poor, and shield effectiveness is bad；The construction of cable is loose installing and very easily deforming because of cable distortion and extruding in use procedure, thus affecting high frequency signal transmission；The water resistance of communication cable, long-time stop easily causes corrosion.
Summary of the invention
It is strong and improve it and use service life, guarantee the communication cable of its steady signal transmission that the purpose of this utility model is to provide a kind of simple in construction, good water-proof effect, anti-tampering property.
The technical solution of the utility model is: a kind of communication cable, including oversheath body, and multiple conductor groups of the interior setting of jacket body outside, it is provided with between conductor group and oversheath body and is filled with ointment, jacket body inner side is provided with water blocking layer outside, and described water blocking layer is waterstop
Described conductor group includes conductor, reveals line, gasket for packing and anti-interference body, is provided with conductor, reveals line, gasket for packing, be provided with leaky line and at least one gasket for packing in conductor both sides in described anti-interference body,
Described anti-interference body includes helical hollow tube, is surrounded by helical hollow tube outside conductor, is surrounded by insulation tube outside helical hollow tube, is surrounded by silver belt outside insulation tube, is surrounded by filamentary silver braid, is surrounded by protecting pipe outside filamentary silver braid outside silver belt,
The heart arranges a center core in the cable, described center core by outside three insulated wire cores successively wrapped polyurethane belting layer, metal screen layer constitute,
Described oversheath body includes being sequentially provided with insulating barrier, double layer screen layer and jacket body from inside to outside, and described jacket body includes inner sheath, braiding armouring and oversheath successively.
Further, described waterstop is by being coated with the corpus fibrosum expanded into that blocks water on non-woven fabrics.
Further, described conductor is silver-plated single crystal Cu.
Further, described insulation tube is plastic tube.
Further, described waterstop is arranged near insulating barrier.
This utility model has the advantage that and has the benefit effect that owing to adopting technique scheme, makes communication cable have good water proofing property, it is adaptable to various working environments, easy to use, and long service life；Reveal line energy equilibrium electrostatic and reveal electrostatic, improving stability and the safety of cable；Owing to the cable core of cable have employed by conductor outsourcing spiral hollow tubular construction, so make the stable signal transmission of communication cable, and advantages of good shielding performance, anti-interference.
