Abstract

The utility model relates to a kind of power line, it comprises at least one conductor, and insulating barrier, the overcoat of coating conductor successively from inside to outside, described overcoat to comprise in the first metal winding layer, first of being coated on successively from inside to outside outside insulating barrier tegillum in tegillum, the second metal winding layer, second, is coated with a braid and serving at described overcoat.The utility model power line adds one deck braid outside overcoat, and this braid can when power line distortion, and mask the electromagnetism of effusion overcoat, the capability of electromagnetic shielding of the utility model power line has larger lifting.

Description

Power line

Technical field

The utility model relates to a kind of power line, particularly relates to a kind of power line with metal winding layer.

Background technology

The structure of existing power line 1000 as shown in Figure 1, it comprises at least one conductor 10, and insulating barrier 20, the overcoat 30 of coating conductor successively from inside to outside, and overcoat 30 to comprise in the first metal winding layer 310, first of being coated on successively from inside to outside outside insulating barrier 2 tegillum 340 in tegillum 320, second metal winding layer 330, second.

For the occasion that electromagnetic shielding requirements is harsh, this power line 1000 often can not be employed because capability of electromagnetic shielding does not reach requirement, its reason is, this power line 1000 is when being twisted, its the first metal winding layer 310, first metal winding layer 330 is also distorted, and causes part electromagnetism effusion power line 1000 and does not have conductively-closed to fall.

So, be necessary carry out certain design to existing power line and improve with the application requirement adapting to harsh electromagnetic shielding.

Utility model content

The power line that the utility model provides a kind of capability of electromagnetic shielding excellent.

The technical scheme that the utility model adopts is: a kind of power line, it comprises at least one conductor, and insulating barrier, the overcoat of coating conductor successively from inside to outside, described overcoat to comprise in the first metal winding layer, first of being coated on successively from inside to outside outside insulating barrier tegillum in tegillum, the second metal winding layer, second, is coated with a braid and serving at described overcoat.

Preferably, the coverage rate of described braid tegillum outer surface in second reaches more than 90%.

Preferably, described braid is formed by zinc-plated copper wire woven.

Preferably, described first metal winding layer to be extended spirally around insulating barrier by zinc-plated copper cash and forms; Described second metal winding layer to be extended spirally around tegillum in first by zinc-plated copper cash and forms.

Preferably, described insulating barrier, in first, second, tegillum and serving are prepared from by PVC material respectively.

Preferably, described conductor is prepared from by zinc-plated copper product.

The utility model power line adds one deck braid and serving outside overcoat, and this braid can when power line distortion, and mask the electromagnetism of effusion overcoat, the capability of electromagnetic shielding of the utility model power line has larger lifting.

Fig. 2 is the structural representation of the utility model power line.

Detailed description of the invention

As shown in Figure 1, the utility model power line 100 comprises at least one conductor 1, and insulating barrier 2, the overcoat 3 of coating conductor 1 successively from inside to outside, is coated with one deck braid 4 and serving 5 at described overcoat 3.

Overcoat 3 to comprise in the first metal winding layer 31, first of being coated on successively from inside to outside outside insulating barrier 2 tegillum 34 in tegillum 32, second metal winding layer 33, second.

Braid 4 becomes network structure by zinc-plated copper wire woven, and braid 4 is attached to tegillum 34 outer surface in second, and the coverage rate of braid 4 tegillum 34 outer surface in second reaches more than 90%.

First metal winding layer 31 to be extended spirally around insulating barrier 2 outer surface by zinc-plated copper cash and forms, and coverage rate reaches 80%; Second metal winding layer 33 to be extended spirally around tegillum 32 outer surface in first by zinc-plated copper cash and forms, and coverage rate reaches 80%.

Insulating barrier 2, in first, second tegillum 32,34 and serving 5 by PVC(Polyvinyl chloride polymer, polyvinyl chloride) material is prepared from.

Conductor 1 is prepared from by zinc-plated copper product.Conductor 1 also can comprise in other embodiments by insulating materials many conductor wires separated from one another.

Compared to existing power line, the utility model adds one deck braid 4 outside overcoat 3, this braid 4 can when power line 100 and the first metal winding layer 31, first metal winding layer 33 distortion, mask the electromagnetism of effusion overcoat 3, therefore, the capability of electromagnetic shielding of the utility model power line 100 has larger lifting.

Although be example object, disclose preferred embodiment of the present utility model, but those of ordinary skill in the art will recognize, when not departing from scope and spirit of the present utility model disclosed in appending claims, various improvement, increase and replacement are possible.
