Abstract
The utility model discloses a shielding cable. The shielding cable includes a conductor group, an insulation layer and an outer sheath arranged successively from inside out. A shielding layer made of a copper foil having a predetermined thickness and a predetermined width and provided with meshes wraps the outer surface of the insulation layer closely in the axial direction of the cable. According to the type and specification of the cable, the predetermined thickness and the predetermined width of the copper foil provided with meshes arranged in an array are selected, and the copper foil is arranged to wrap the outer surface of the conductor group, so that the shielding layer is formed. The shielding cable has characteristics of saving shielding space and saving manufacturing cost; and being good in flexibility and high in manufacturing efficiency.
Description
Technical field
The utility model relates to cables manufacturing field, relates in particular to a kind of shielded type cable.
Background technology
Shielded type cable is after cable cabling, to add upper shielding layer, utilizes screen to electromagnetic reflection, absorption and skin effect, realizes and prevents that external electromagnetic interference from entering cable, also stops internal signal to radiate the work of disturbing miscellaneous equipment simultaneously.Textural from what shield, screen has started development in pluralism, is coated and shields, to using the shielding plastic technology etc. of directly using from the coated shielding of metal forming, metal wire knitted shielding and Alloy Foil.
Prior art mostly adopts copper wire to weave and forms screen, and the shielding space taking is large, and flexible general, consumptive material and the efficiency of making are lower.
Utility model content
The technical problems to be solved in the utility model is, large for the above-mentioned shielding space taking of prior art, and flexible general, consumptive material and the lower defect of efficiency of making, provide a kind of shielded type cable.
It is a kind of shielded type cable of structure that the utility model solves the technical scheme that its technical problem adopts, described shielded type cable comprises conductor group, insulating barrier, oversheath from inside to outside successively, on the axial direction of described cable, the outer surface of being close to described insulating barrier is surrounded with the screen that the meshed Copper Foil of tool of preset thickness and predetermined width forms.
In shielded type cable described in the utility model, described preset thickness is 0.05～0.16mm.
In shielded type cable described in the utility model, described predetermined width is 6～40mm.
In shielded type cable described in the utility model, the wrapped Duplication of described Copper Foil is 0～5%.
In shielded type cable described in the utility model, between described insulating barrier and described screen, be also wound with at least one metal drain wire, described metal drain wire is for guaranteeing the continuity of the shielding of described shielded type cable.
In shielded type cable described in the utility model, described screen outer surface also has one deck zinc-plated, and described zinc-plated thickness is 0.1～1 μ m.
In shielded type cable described in the utility model, described mesh is arrayed, and described mesh is any in circular port, square opening, tri-angle-holed and diamond hole, and the area of described mesh is 0.0025～0.01mm
2.
Implement shielded type cable of the present utility model, there is following beneficial effect: according to cable model specification, selection has preset thickness and the predetermined width of the Copper Foil of arrayed mesh, the wrapped outer surface in conductor group of Copper Foil is formed to screen, so have the shielding space of saving, flexible fine, save manufacturing cost and make the feature that efficiency is high.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:
Fig. 1 is the profile of the utility model shielded type cable;
Fig. 2 is the enlarged drawing of screen of the first embodiment of the utility model shielded type cable;
Fig. 3 is the enlarged drawing of screen of the second embodiment of the utility model shielded type cable.
Embodiment
For technical characterictic of the present utility model, object and effect being had more clearly, understand, now contrast accompanying drawing and describe embodiment of the present utility model in detail.
Fig. 1 is the profile of the utility model shielded type cable.
Shielded type cable comprises conductor group 30, insulating barrier 40, screen 50, oversheath 60 from inside to outside successively, and insulating barrier 40 is coated on conductor group 30 outer surfaces, and screen 50 is coated on insulating barrier 40 outer surfaces, and oversheath 60 is coated on the outer surface of screen 50.Wherein, screen 50 is by wrapped formation of Copper Foil of the meshed preset thickness of tool and predetermined width.Select that Copper Foil is wrapped to be compared with proof copper-wire braided technology, have the shielding space of saving, flexible fine, save manufacturing cost and make the feature that efficiency is high.
Wherein, also comprise a metal drain wire 45 between insulating barrier 40 and screen 50, metal drain wire 45 is for guaranteeing the continuity of shielded type cable shielding in the axial direction.
The preset thickness of Copper Foil can be 0.05～0.16mm.The selection of preset thickness affects the flexibility of Copper Foil, and preset thickness is less, and flexibility is better, more saves shielding space.
Described predetermined width is 6～40mm.Predetermined width affects the flexibility of Copper Foil equally, and the selection of predetermined width will be determined according to the model specification of cable.
The wrapped Duplication of described Copper Foil is 0～5%.
Described mesh is arrayed, and described mesh is any in circular port, square opening, tri-angle-holed and diamond hole.The area of described mesh is 0.0025～0.01mm
