Multifunctional cable of sound equipment

Abstract

A multifunctional audio cable, which comprises a composite shielding layer, a plurality of insulating cores formed of composite conductors and insulating layers arranged in the composite shielding layer, fillers and a sheath layer arranged outside the composite shielding layer; The conductor includes a center conductor and an outer conductor twisted around the center conductor, the composite shielding layer includes an insulating shielding layer, an anti-interference drain wire, a wrapping tape and a metal wire braid; the anti-interference and drain wire is twisted together with the insulated wire core The composite cable is closely attached to the insulating shielding layer of the insulated core; it adopts the composite conductor and composite shielding structure to overcome the problems of large transmission attenuation and signal mixing of the existing audio cable, and the overall structure is scientific and reasonable, and the installation is simple, which can ensure the internal safety of the cable. Each conductor will not interfere with each other when transmitting large current, and the external electromagnetic interference signal is isolated outside the cable; it is widely used in home audio equipment.

Description

technical field [0001] The invention relates to a multifunctional audio cable. Background technique [0002] At present, there are the following situations in the common audio cables commonly used in households on the market: ① Ordinary products use several low-oxygen bare copper stranded wires with the same diameter of monofilament as conductors, so the structure is single, resulting in large transmission attenuation, mixed signals, high , middle and bass can not be distinguished; ② Ordinary products use ordinary polyvinyl chloride as insulating material, so that the characteristic impedance cannot be matched, resulting in large transmission attenuation and sound distortion; ③ Ordinary products have no shielding structure or a single shielding structure, resulting in signal Mutual interference, easy to generate noise; ④ Ordinary products have no sheath, and the insulation layer and conductor core are easily damaged during installation and use.
