Description
Technical field
The present invention relates to electric wire field, be specifically related to a kind of multifunctional room external high-power coaxial photoelectricity and be combined flexible cable.
Background technology
World today's stepped into information epoch, information has become the strategic resource of economic development and unique production factors, combine the present information transmission system and complete information service system set up with multimedia terminals such as telecommunications network, computer, videos, it has also become the important symbol of a country economic development level.
Coaxial optical fiber cable is the important kind of one in information transmission, is mainly used as radio transmitting or feeder and various communication, the machine intraconnections of electronic equipment of the equipment of reception or is connected with each other line.Coaxial cable is made up of inner conductor layer, insulating barrier, outer conductor layer and restrictive coating, inner conductor layer and the usual cross section of outer conductor layer are the least, from carrying poor performance, when especially cable uses under the most buried operating mode, owing to load-carrying properties are poor, cable own wt can make cable conductor break, and the most easily damages tiny cable conductor when in construction simultaneously.Prior art uses bracing frame to be supported cable; coaxial cable is protected by the form increasing bracing frame; there is certain effect; but add laid down cost and time; in addition the load-carrying properties of cable own are poor, unavoidably can be because operation causes the problem that the core of cable damages accidentally in work progress；The moistureproof and waterproof of existing optical fiber composite cable is the poorest, in the case of humidity, affects the performance of cable.
Summary of the invention
In order to overcome the deficiencies in the prior art, it is provided that a kind of have the strongest from load-carrying properties and tensile property, and moistureproof and waterproof performance is good, good stability, multifunctional room external high-power coaxial photoelectricity easy for installation are combined flexible cable.
For achieving the above object, the invention discloses a kind of multifunctional room external high-power coaxial photoelectricity and be combined flexible cable, include conductor center carrying core, tubular inner conductor, insulating barrier, screen layer, impermeable stratum, outer conductor, inner sheath and metallic conduction pipe from inside to outside；Outer conductor is wound around side by side by many tension tinsels and combines；Described metallic conduction pipe is externally provided with the damp-proof layer that part is squeezed mutually with metallic conduction pipe；Gap, both sides outside metallic conduction pipe and in damp-proof layer is provided with one group of fiber unit；Elastic protective is filled in gap between metallic conduction pipe, damp-proof layer and fiber unit three；Being additionally provided with fixing tongue on damp-proof layer, the height of described fixing tongue is not less than 4mm, and width is not less than 2mm.
Preferably, described conductor center carrying core is zinc-coated wire.
Preferably, described fiber unit is by optical fiber and the protection set that is extruded in outside optical fiber.
Preferably, described metal compression tube is the hard compression tube of wrapped or vertical bag, specially embossing pipe.
The beneficial effects of the present invention is:
The present invention has the strongest from load-carrying properties, the conductor center layer You Yigen center carrying core of cable, and the stress point of inner wire concentrates on center carrying core, and cable, in folding and unfolding winding process, protects inner wire annealing copper wire, and is not easily broken；It is wound around tension tinsel simultaneously outside outer conductor and improves the overall tensile property of cable；Metallic conduction pipe compressive property is good, and moistureproof and good airproof performance, embossing can improve its bending property；Cable entirety is full symmetrical configuration, and copper wire and zinc-coated wire have function of shielding, and inner and outer conductor is in concentric position, and electromagnetic energy is confined to the media between internal and external conductor, therefore has decay little, and shielding properties is high；With one group of fiber unit, be used interchangeably or one be broken, can use at once, to maintenance bring the biggest convenience, saved the use time of user；Described impermeable stratum is made up of thermoplasticity low-density polyethylene material, when cable runs into moisture or is placed in the occasion of humidity, can effectively stop the intrusion of moisture, considerably increase the service life of cable, also improve the property that cable uses；Insulating barrier and the electrical property of damp-proof layer and mechanical performance have each obtained optimal performance, make up mutually, synergism, and damp-proof layer compensate for that insulating barrier is ventilative, the defect of moisture-sensitive, and damp-proof layer not only gives full play to moisture-proof role, simultaneously works as the effect of second insulation；Outer damp-proof layer is oval, when laying fixing, is difficult to roll；Being squeezed when, have the space of buffering, substantially increase the rounding property of cable, also improve the service life of cable；Damp-proof layer is additionally provided with fixing tongue, outside during laying installation, easily fixes, bring convenience to construction.
