Abstract
The utility model discloses a tensile wear-resisting earphone wire harness, which comprises a protective layer and a shielding layer, wherein an earphone wire harness cable core is arranged in the shielding layer, four conductive wire cores respectively coated by a polyethylene insulating layer are arranged in the earphone wire harness cable core, each conductive wire core is formed by twisting seven winding wires, and each winding wire is formed by coating a tinned copper flat wire outside an aramid fiber filament. The tensile wear-resisting earphone wire harness adopts the special structural design and materials, has the advantages of tension resistance, low temperature resistance, wear resistance, tensile strength and flame retardance, and is applicable to wire harnesses used for communication and transmission of earphones on helmets of drivers in extreme severe environments such as field combat vehicles and aircraft.
Description
Technical field
The utility model relates to a kind of earphone wire harness, specifically a kind of tensile wear-resistant earphone wire harness being applied in the extreme severe rugged environment such as field battlebus, aircraft.
Background technology
At present, traditional headphone cable mainly adopts bare copper wire twisted bundles to become conductor, and insulation and sheath are that PVC material forms, and this is mainly used in general service and uses, and this type of headphone cable process alternating bending is disconnected core easily, uses insulation to occur rupturing under low temperature environment.Once this earphone is applied to military field, to pilot and operational commanding, will form serious threat, so field battlebus and the aircraft helmet, to earphone wire harness, specific requirement, i.e. tension have been proposed, resistance to bending, when wear-resisting, low temperature resistant environment is worn simultaneously to skin without allergic reaction etc.
Utility model content
The purpose of this utility model is to provide a kind of tensile wear-resistant earphone wire harness, the deisgn product of carrying out for shortcoming in the technology of background, this wire harness is on the basis of original cable, improved the tension of wire harness, resistance to bending, wear-resisting, low temperature resistant environmental performance, when simultaneously personnel wear to its skin without allergic reaction.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: a kind of tensile wear-resistant earphone wire harness, it comprises overcoat, screen, in described screen, be provided with earphone wire harness cable core, in earphone wire harness cable core, be provided with four conductor wire cores that wrapped up by polyethylene layer, described conductor wire core is to be combined into by seven winding skein silks, and described winding silk is wrapped with by aramid fiber silk that tin-coated copper lenticular wire is stranded to be formed.
Described tin-coated copper lenticular wire is equidistantly wrapped on aramid fiber silk.
Described screen adopts wire netting material.
Described overcoat is nylon yarn material.
Its operation principle is as follows: adopt aramid fiber silk as heart, the outer employing of aramid fiber silk tin-coated copper lenticular wire is wrapped in aramid fiber silk according to fixing pitch and has formed a tin-coated copper lenticular wire winding silk outward, tin-coated copper lenticular wire is wound around the unique texture form that adopted, tensile strength and bending ability have been improved, comparing tradition is compared as the earphone of conductor thread core by simple copper cash, useful life and the reliability of earphone have been increased, adopt seven winding silks to be combined into conductor wire core, this conductor wire core tensile strength is high, can bear the heavy burden bending under adverse circumstances, outside conductor wire core, melting extrudes layer of polyethylene insulating barrier, polyethylene layer than traditional PVC do insulate more low temperature resistant, have good dielectric property simultaneously, by wire harness, process, four above-mentioned conductor wire cores are processed into earphone wire harness cable core, the outer high-speed knitter braiding formation layer of metal net that adopts of earphone wire harness cable core has formed beam shield layer, effectively resisted electromagnetic interference, described protective jacket adopts the braiding of black nylon silk to form, increased the resistance to wear of wire harness, wire harness has good pliability simultaneously, increase driver's comfortable wearing degree.
In sum, the utility model advantage is as follows: this utility model has simple in structure, adopts unique version, improves product useful life, compared better anti-electromagnetic interference capability with traditional earphone wire harness, wear-resisting, low temperature resistant, more can adapt to adverse circumstances.
