Description

Anti-interference audio cable

Technical Field

The utility model relates to a wire and cable technical field especially relates to an anti-interference audio frequency wire and cable.

Background

Cables are generally rope-like cables made by stranding several or groups of conductors (at least two in each group), each group being insulated from each other and often twisted around a center, the entire outer surface being coated with a highly insulating coating. The cable has the characteristics of internal electrification and external insulation. The cable comprises a power cable, a control cable, a compensation cable, a shielding cable, a high-temperature cable and a computer

Cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, and the like. They are composed of single or multi-strand wires and insulating layers, and are used for connecting circuits, electric appliances and the like. However, the common cable is lack of anti-interference design, the signal is not stable enough in the operation of the cable, and the performance of the cable is reduced.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that an adopt the design that the parcel has aluminium foil wheat to draw and tinned wire to weave the shielding layer on the inner conductor is provided, can make the cable anti-interference, guarantee the stability of signal in the cable operation, improved the anti-interference audio frequency wire and cable of cable performance.

In order to solve the technical problem, the utility model provides an anti-interference audio cable, including oversheath layer, shielding layer, aluminium foil wheat draw, insulating layer and inner conductor, its characterized in that, the oversheath in situ is connected with the shielding layer, be connected with the aluminium foil wheat in the shielding layer and draw, the aluminium foil wheat draws the in-connection and has the insulating layer, be connected with the inner conductor in the insulating layer, the aluminium foil wheat draws and is the infundibulate structure, the inner conductor is equipped with many, and it has the one deck insulating layer to all wrap up on the every inner conductor.

Furthermore, the shielding layer is a tinned copper wire braided shielding layer.

Furthermore, the aluminum foil mylar is formed by adopting a metal aluminum foil as a base material and attaching the metal aluminum foil to a polyester tape after being glued, and the thickness of the aluminum foil mylar is 4 UM.

Further, the insulating layer is a polyvinyl chloride insulating layer.

Further, the inner conductor is a copper core conductor.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses a parcel has the design that aluminium foil wheat drawn and tinned wire woven shield layer on the inner conductor, can make the cable anti-interference, guarantees the stability of signal in the cable operation, has improved the cable performance.
