Abstract
The utility model discloses a kind of anti-interference audio frequency electric wire, including cable core, screen layer, metal surrounding layer, sprayed metal coating and fire-retardant external sheath layer, described cable core outer wrapping is provided with insulating barrier, described screen layer it is provided with outside described insulating barrier, described metal surrounding layer fixed packet is rolled in outside described screen layer, described sprayed metal coating is located at outside described metal surrounding layer, and described fire-retardant external sheath layer is located at outside described sprayed metal coating.By the way, this utility model can design the anti-interference improving cable by the metallic shield of cable surrounding layer so that cable performance is more stable, and cable outer layer also has corresponding insulation, heat-resisting and reinforcement performance design, preferably improves cable performance.
Description
Technical field
This utility model relates to field of cables, particularly relates to a kind of anti-interference audio frequency electric wire.
Background technology
Cable is typically the cable of the similar rope stranded by several or several groups of wires (often organizing at least two), often mutually insulated between group wire, and is often twisted into round a center, and whole outside is surrounded by the cover layer of high-insulation.Cable has interior energising, the feature of external insulation.Cable has power cable, controls cable, compensating cable, shielded cable, high-temperature cable, computer cable, signal cable, coaxial cable, fire-resisting cable, cable for ship, mine cable, aluminium alloy cable etc..They are all made up of sub-thread or stranded conductor and insulating barrier, are used for connecting circuit, electrical equipment etc..But general cable lacks Anti-interference Design, in cable runs, signal is not sufficiently stable, and reduces cable performance.
Utility model content
This utility model is mainly solving the technical problems that provide a kind of anti-interference audio frequency electric wire, it is possible to designed the anti-interference improving cable by the metallic shield of cable surrounding layer so that cable performance is more stable.
For solving above-mentioned technical problem, the technical scheme that this utility model uses is: provide a kind of anti-interference audio frequency electric wire, including cable core, screen layer, metal surrounding layer, sprayed metal coating and fire-retardant external sheath layer, described cable core outer wrapping is provided with insulating barrier, described screen layer it is provided with outside described insulating barrier, described metal surrounding layer fixed packet is rolled in outside described screen layer, described sprayed metal coating is located at outside described metal surrounding layer, and described fire-retardant external sheath layer is located at outside described sprayed metal coating.
In one preferred embodiment of this utility model, described sprayed metal coating is made up of with binding agent metal dust, and metal dust passes through spray gun spraying outside described metal surrounding layer after mixing with binding agent.
In one preferred embodiment of this utility model, described metal surrounding layer end face outside is provided with multiple salient point, and the metal surrounding layer surface between described salient point is groove surface, overrides described salient point during the spraying of described sprayed metal coating.
The beneficial effects of the utility model are: this utility model can design the anti-interference improving cable by the metallic shield of cable surrounding layer, make cable performance more stable, cable outer layer also has corresponding insulation, heat-resisting and reinforcement performance design, preferably improves cable performance.
