The high-flame-retardant linear wire harness comprises a plurality of wire harness single bodies, each wire harness single body comprises a wire core conductor, each wire core conductor is wrapped by an inner shielding layer and sleeved with an insulating sleeve, and the outer side of each insulating sleeve is sleeved with an outer shielding layer; the inner flame-retardant sleeve sleeves a plurality of wire harness monomers, and glass fibers are filled between the wire harness monomers and between the wire harness monomers and the inner flame-retardant sleeve; the outer flame-retardant sleeve wraps the outer side of the inner flame-retardant sleeve, the outer flame-retardant sleeve comprises a PVC inner sleeve layer, a halogen-free flame-retardant sleeve and a flame-retardant filling layer located between the PVC inner sleeve and the halogen-free flame-retardant sleeve, and an expandable and stretchable metal net layer is embedded in the flame-retardant filling layer. According to the invention, the wire harness monomers are coated by the inner flame-retardant sleeve, so that the flame retardance is enhanced, meanwhile, the outer flame-retardant sleeve is continuously coated outside, the PVC inner sleeve and the halogen-free flame-retardant sleeve are used for internal and external protection, and the flame-retardant filling layer is filled in the middle, so that the flame retardance of the automobile wire harness is further enhanced.

    本发明公开了一种高阻燃线性线束,包括多根线束单体,线束单体包括线芯导体,线芯导体由内屏蔽层包覆,并套设绝缘套,绝缘套外侧套设外屏蔽层;内阻燃套,内阻燃套套设多根线束单体,且线束单体之间及与内阻燃套之间填充玻璃纤维;包覆于内阻燃套外侧的外阻燃套,外阻燃套包括PVC内套层、无卤阻燃套、及位于PVC内套和无卤阻燃套之间的阻燃填充层,阻燃填充层预埋有可膨胀拉伸的金属网层。本发明通过内阻燃套包覆线束单体,增强阻燃性,同时外部继续包覆外阻燃套,利用其PVC内套和无卤阻燃套内外防护,中间填充阻燃填充层,进一步加强汽车线束的阻燃性能。
