Abstract
The utility model discloses a microphone lead, comprising two core wires twisted with each other. A conductor of the core wire is formed by mutual twisting of a copper wire and a tinning copper-foil wire. A polyester silk layer, an aluminium foil layer and a sheath are covered outside of the core wire from inside to outside. The tinning copper-foil wire and a bare copper wire are arranged between the sheath and the aluminium foil layer. The conductor of the core wire used by the utility model is formed by mutual twisting of the copper wire and the tinning copper-foil wire and the core wire conductor has certain tension and a bending-damage resistant performance by design. The polyester silk layer, the aluminium foil layer and the sheath are covered outside of the core wire from inside to outside; and the tinning copper-foil wire and the bare copper wire are arranged between the sheath and the aluminium foil layer in order to transmit audio signals and have a conductive function. The tinning copper-foil wire has an oxidation resistant effect and the bare copper wire is convenient for subsequent welding processing. The polyester silk layer is used for effectively protecting the core wires and is flexibility resistant and stretching resistant.
Description
Technical field
The utility model relates to a kind of microphone conductor, especially a kind of anti-flexible, oxidation resistant microphone conductor.
Background technology
At present, in the higher place of microphone conductor frequency of utilization, often see microphone conductor and infringement occurs, so long as because the skin of present microphone conductor is the PVC material, be provided with conductor in the skin, the conductor part adopts the fine copper silk basically, be subjected to the restriction of common PVC material and copper wire inherent characteristic, the bend resistance poor performance of this microphone conductor, and also the oxidation resistance of product is not high yet, thereby cause product easily to damage, be difficult to meet people's instructions for use.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of anti-flexible, oxidation resistant microphone conductor.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of microphone conductor, it comprises two mutual stranded heart yearns, the conductor of described heart yearn is mutually linked by copper wire and zinc-plated copper foil wire and forms, described heart yearn is provided with zinc-plated copper foil wire and bare copper wire from inner dacron thread layer, aluminium foil layer and the crust of outwards being coated with between described crust and the aluminium foil layer.
As improvement of the technical scheme, described crust is the frosting structure.
As further improvement in the technical proposal, described copper wire and zinc-plated copper foil wire quantity ratio are 1～10: 1.
The beneficial effects of the utility model are: the conductor of the heart yearn that this product uses is mutually linked by copper wire and zinc-plated copper foil wire and forms; this design is so that cored wire conductor possesses certain pulling force and anti-bending damage performance; described heart yearn is from the inner dacron thread layer that outwards is coated with; aluminium foil layer and crust; be provided with zinc-plated copper foil wire and bare copper wire between described crust and the aluminium foil layer; in order to play transmission of audio signal and conducting function; zinc-plated copper foil wire plays oxidation resistant effect; and the convenient follow-up welding processing of bare copper wire; heart yearn can be effectively protected in use as for the dacron thread layer, and anti-flexible; stretch-proof.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of utility model.
Embodiment
With reference to Fig. 1; a kind of microphone conductor; it comprises two mutual stranded heart yearns 1; the conductor of described heart yearn 1 is mutually linked by copper wire 11 and zinc-plated copper foil wire 12 and forms; described copper wire 11 and zinc-plated copper foil wire 12 quantity ratio are 1～10: 1; this design is so that cored wire conductor possesses certain pulling force and anti-bending damage performance; described heart yearn 1 is from the inner dacron thread layer 2 that outwards is coated with; aluminium foil layer 3 and crust 5; be provided with zinc-plated copper foil wire and bare copper wire between described crust 5 and the aluminium foil layer 3; in order to play transmission of audio signal and conducting function; it arrives oxidation resistant effect zinc-plated copper foil wire; and the convenient follow-up welding processing of bare copper wire; heart yearn can be effectively protected in use as for dacron thread layer 2, and anti-flexible; stretch-proof.
In addition, this product with crust 5 for being set to the frosting structure, thereby effectively play the effect of anti-soil, antiskid.
This product is owing to having anti-flexible, oxidation resistant effect, thereby can be widely used in the making of microphone conductor.
