Abstract
The invention discloses a high-frequency shield wire which sequentially comprises an internal conductor wire core, an insulating layer, an aluminum foil, a first tin annealed copper wire braided layer, a second tin anneal copper wire braided layer and an insulating sheath layer from inside to outside. The high-frequency shield wire is not easy to attenuate and is good in shielding effect, and the shielding property of the high-frequency shield wire keeps excellent after the high-frequency shield wire is bent or twisted repeatedly.
Description
Technical field
The present invention relates to a kind of high frequency shielding conductor, belong to the cable technology field.
Background technology
At present; in the shielding conductor use procedure; often the phenomenons such as bending and torsion can occur, when this phenomenon increased frequency, produce broken string or metal forming in the bundle conductor of formation wire sheathing and can occur damaging; and its breakage develops into the resistance that causes electro-magnetic screen layer increases＜conductance is low 〉; thereby that has destroyed shielding conductor passes through characteristic or shielding character, in addition, and also than being easier to decay; after long-time the use, shielding conductor can lose the effect of its shielding.
Summary of the invention
Technical problem to be solved by this invention is the defective that overcomes prior art, and a kind of decay that is not easy is provided, and shield effectiveness is good, though when bending or number of torsions increase its shielding properties good high frequency shielding conductor still.
The present invention solves the problems of the technologies described above the technical scheme of taking: a kind of high frequency shielding conductor, it comprises inner conductive core, insulating barrier, aluminium foil, the first tin annealed copper wire braid, the second tin annealed copper wire braid and insulating sleeve layer from inside to outside successively.
Adopted technique scheme, the present invention has following beneficial effect:
1, shielding properties of the present invention is strengthened, because the present invention used two-layer electromagnetic shielding braid and one deck aluminium foil, its shield effectiveness is obviously effective than individual layer or two-layer.
2, useful life, more common shielded type cable was long, and double-deck electromagnetic shielding braid has reduced the probability of the fracture of braided wire, has greatly increased its useful life.
Even 3, the present invention is when bending or number of torsions increase, its shielding properties is still good.Even the present invention is when the braided wire of the first tin annealed copper wire braid or the second tin annealed copper wire braid produces fracture or aluminium foil and is damaged, also can compensate by the braided wire of other electro-magnetic screen layers by the part of defective, even when bending or number of torsions increased, its shielding properties was still good.
4, two-layer electro-magnetic screen layer all adopts the tin annealed copper wire braiding, can prevent that insulating barrier or insulating protective layer are clamminess, and the core blackout becomes fragile, and improves its solderability.
Description of drawings
Fig. 1 is the structural representation of high frequency shielding conductor of the present invention.
Embodiment
Content of the present invention is easier to be expressly understood in order to make, and the below is according to specific embodiment and by reference to the accompanying drawings, and the present invention is further detailed explanation.
As shown in Figure 1, a kind of high frequency shielding conductor, it comprises inner conductive core 1, insulating barrier 2, aluminium foil 3, the first tin annealed copper wire braid 4, the second tin annealed copper wire braid 5 and insulating sleeve layer 6 from inside to outside successively.Like this, shielding properties of the present invention is strengthened, because the present invention used two-layer electromagnetic shielding braid and one deck aluminium foil 3, its shield effectiveness is obviously effective than individual layer or two-layer; Useful life, more common shielded type cable was long, and double-deck electromagnetic shielding braid has reduced the probability of the fracture of braided wire, has greatly increased its useful life; Even the present invention is when the braided wire of the first tin annealed copper wire braid 4 or the second tin annealed copper wire braid 5 produces fracture or aluminium foil 3 and is damaged, also can compensate by the braided wire of other electro-magnetic screen layers by the part of defective, even when bending or number of torsions increased, its shielding properties was still good; Two-layer electro-magnetic screen layer all adopts the tin annealed copper wire braiding, can prevent that insulating barrier or insulating protective layer are clamminess, and the core blackout becomes fragile, and improves its solderability.
Insulating barrier 5 can adopt the polyethylene foamed material to make.
Inner conductive core 1 can adopt some annealed copper wire strands to consist of together.
Above-described specific embodiment; purpose of the present invention, technical scheme and beneficial effect are further described; institute is understood that; the above only is specific embodiments of the invention; be not limited to the present invention; within the spirit and principles in the present invention all, any modification of making, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
