Abstract
A high-strength anti-interference telephone signal transmission line comprises conductive cores (1) and a cladding (4), wherein three conductive cores (1) are covered inside the cladding (4), insulation layers are respectively covered outside the three conductive cores (1) to form insulated cores (2), and shielding layers (3) are respectively covered on a left insulated core (2) and a right insulated core (2). The high-strength anti-interference telephone signal transmission line has particularly fine anti-tensile and anti-bending performances, and the cores can not fracture even after being bended 180 thousands of times. Besides, the shielding layers are covered outside conductive cores of main loops, and the anti-interference performance is good, accordingly the transmission line guarantees telephone signal transmission to be steady and clear under complex electromagnetic environments having staggered circuits, such as rapid transit railway, metro, city train, mine and the like.
Description
Technical field
The utility model relates to the anti-interference telephone signal transmission line of a kind of high strength.
Background technology
Traditional telephone signal transmission line all is directly to be core with the metal wire; outside coating insulating material provides protection to the metal wire of inside; reach the purpose of transmission signals; long-term use is constantly pullled, bending action easily fractures metal core wire, exposes the defective that the black phone transmission line exists low, the not anti-bending of intensity, interference free performance difference.Develop rapidly along with China's electrified high-speed railway and urban rail transit technology, the environment for use of car phone is subjected to the interference of various electromagnetic signals, require its supporting telephone transmission line not only to want intensity height, good springiness, anti-bending, and anti-electromagnetic field disturbs, guarantee telephone signal transmission stablize clear.As seen the black phone transmission line is difficult to meet the demands.
Summary of the invention
The technical problem that the utility model solves: design the anti-interference telephone signal transmission line of a kind of high strength; adopt the polypropylene material of good-toughness to extrude insulated wire cores; and two major loop insulated wire cores outer wrapping screens; outermost layer extrudes environmental protection, fire-retardant new polyurethane protective layer, makes the telephone signal transmission line have good high strength, anti-bending, interference free performance under the staggered complex environments such as high-speed railway, subway, city train and mine of circuit.
Technical solution of the present utility model: the anti-interference telephone signal transmission line of a kind of high strength comprises conductor wire core (1) and protective layer (4).Be enclosed with three conductor wire cores (1) in the protective layer (4), the outer wrap insulate layer respectively of three conductor wire cores (1) forms insulated wire cores (2), and about two thoroughly do away with the outer screen (3) that wraps up respectively of edge cores (2).
Described conductor wire core (1) is by four tinsel conductors (6) and be positioned at central polyamide fibre reinforced wire (5) formation of four tinsel conductors (6), and the outer polypropylene insulation layer that extrudes of four tinsel conductors (6) forms insulated wire cores (2).
Described screen (3) adopts zinc-plated circular copper wire to work out.Described protective layer (4) adopts the new polyurethane material to extrude and forms.Described tinsel conductor (6) is made of the Copper Foil (8) that Polyamide Yarns (7) and helical form are wound on the Polyamide Yarns (7).
Advantage that the utility model compared with prior art has and effect:
1, the utility model conductor wire core has good especially stretching resistance and bend resistance performance, and it bends continuous core 180,000 times.
2, the utility model major loop conductor wire core outer wrapping screen, interference free performance is good, under the staggered complex electromagnetic environments such as high-speed railway, subway, city train and mine of circuit, guaranteed telephone signal transmission stablize clear.

Embodiment
1,2,3 a kind of embodiment of the present utility model is described in conjunction with the accompanying drawings.
The anti-interference telephone signal transmission line of a kind of high strength; comprise conductor wire core 1 and protective layer 4; be enclosed with three conductor wire cores that are arranged side by side 1 in the protective layer 4; the three conductor wire core 1 outer parcel of parcel respectively polypropylene insulation layers form insulated wire cores 2; and about two thoroughly do away with the screens 3 that edge cores 2 outer parcels respectively adopt zinc-plated circular copper wire to work out; be used for the shielding of interference source to external world, interference free performance is good.Conductor wire core 1 is made of four tinsel conductors 6 and the polyamide fibre reinforced wire 5 that is positioned at four tinsel conductor 6 central authorities, tinsel conductor 6 is made of the Copper Foil 8 that Polyamide Yarns 7 and helical form are wound on the Polyamide Yarns 7, make conductor wire core 2 have good especially stretching resistance and bend resistance performance, it bends continuous core 180,000 times.
During use the utility model turned to spring molded lines 9, the two ends general crystal head 10 of riveting telephone set of letting the hair grow becomes the anti-interference phone assembly line of high strength, it can be in stretchings up to ten thousand time resilience rapidly, nearly 200,000 continuous cores that circumnutate, guaranteed telephone signal transmission stablize clear.The utility model is not limited to the foregoing description, can increase or reduce the conductor wire core radical as required.
