Interior flat excircle USB2. 0 electric wire

The utility model provides an interior flat excircle USB2.0 electric wire, restrictive coating including cable core, shielding layer and pipe shape, the cable core strands into the flat winding displacement of circular form for many heart yearns, the shielding layer cladding in the outside of cable core, the restrictive coating cladding in the outside of shielding layer, the heart yearn include conductor line and cladding in the insulating layer in the conductor line outside. The flat winding displacement that the cable core formed for the transposition of many heart yearns, heart yearn be through disposable cladding, for traditional quartic nature cladding, greatly reduced the cost of labor, diminish through transposition messenger wire rod physique, be convenient for the shielding layerreaches the cladding of restrictive coating to reach the little and mild mesh of electric wire external diameter, practice thrift the cost of labor simultaneously, improved production efficiency. 本实用新型提供了种内扁外圆USB2.0电线，包括缆芯、屏蔽
