Abstract
The utility model discloses a high frequency wave shielding line, which comprises an internal conductor core, an insulation layer, an aluminum foil, a first tinned soft copper wire braid layer, a second tinned soft copper wire braid layer and an insulation sheath which are arranged in turn from outside to inside. The high frequency wave shielding line does not easily attenuate, the shielding effect is good, and even though the bending or torsion times are increased, the shielding performance is still good.
Description
Technical field
The utility model relates to a kind of high frequency waves shielding conductor, belongs 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.
The utility model content
Technical problem to be solved in the utility model 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 waves shielding conductor still.
The utility model solves the problems of the technologies described above the technical scheme of taking: a kind of high frequency waves 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.
Adopt technique scheme, the utlity model has following beneficial effect:
1, shielding properties of the present utility model is strengthened, because the utility model 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 utility model is when bending or number of torsions increase, its shielding properties is still good.Even the utility model 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 waves shielding conductor of the present utility model.
Embodiment
Content of the present utility model is easier to be expressly understood in order to make, and the below is described in further detail the utility model according to specific embodiment also by reference to the accompanying drawings.
As shown in Figure 1, a kind of high frequency waves 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 utility model is strengthened, because the utility model 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 utility model 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; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above only is specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
