Utility model content
The purpose of this utility model is to provide a kind of digital cable, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of digital cable, comprise internal protective cover, copper conductor, insulating barrier, high strength fibre yarn, water blocking layer, crossing skeleton, horizontal aluminum skeleton, vertical aluminum skeleton, aluminium foil layer, elastic gel, polyvinylidene chloride diaphragm, screen and flame resistant protective layer, described internal protective cover inside is containing two copper conductors, described copper conductor crust is enclosed with insulating barrier, described internal protective cover inwall is evenly provided with one deck high strength fibre yarn, described high strength fibre yarn outer wrap has water blocking layer, be connected with crossing skeleton outside described internal protective cover, described crossing skeleton inside is embedded with horizontal aluminum skeleton and vertical aluminum skeleton, described crossing skeleton end is connected with aluminium foil layer, elastic gel is filled with between described aluminium foil layer and crossing skeleton, described aluminium foil layer outer wrapping polyvinylidene chloride diaphragm, described polyvinylidene chloride diaphragm outer wrapping one deck screen, described screen is wrapped with one deck flame resistant protective layer.
Preferably, described high strength fibre yarn is made up of high density polyethylene material.
Preferably, described water blocking layer by indulge alclad plastic composite strip adopt melten gel weld after, extrude PE sheath and make.
Preferably, described crossing skeleton end exposes horizontal aluminum skeleton and vertical aluminum skeleton, and aluminum skeleton and aluminium foil layer are electrical contact.
Preferably, described elastic gel contains waterproof paste.
Preferably, described screen is worked out by five to ten copper wires.
Preferably, described flame resistant protective layer is made up of the tension rubber of crosslinked polyethylene.
Compared with prior art, the beneficial effects of the utility model are: the outer provided with shielding layer of this digital cable, most of electromagnetic radiation can be shielded, ensure healthy when using of user, the aluminum crossing skeleton adopted and aluminium foil layer electric contact structure, transmission consumption is made to drop to minimum, decrease return loss simultaneously, characteristic impedance and crosstalk attenuation, the multilayer flashing adopted and anti-flaming structure, make to use the impact not by extraneous undesirable element in layer, Signal transmissions is more complete, the polythene material protective layer adopted and high strength fibre yarn, substantially increase cable tensile strength, meet the requirement of outdoor application.
