Aiming at the deficiencies of the prior art, the utility model provides an electric wire for automobiles, which has good shielding performance, bending performance and good fireproof performance.

The technical scheme of the utility model is: an electric wire for automobiles, including six core wires, characterized in that: an aluminum foil strip wrapped around the outer body of the six core wires, the outer body of the aluminum foil strip is covered with a fireproof coating, and the fireproof coating The surface of the outer body of the mica tape is covered with a mica tape, and the outer surface of the mica tape is covered with an external insulating layer; the six core wires are respectively a ground wire, two audio wires for transmitting signals, and three power wires. The colors are different, the ground wire is set at the center of the circular cross-section of the outer insulating layer, and the rest of the rootless wires are evenly distributed around the ground wire, and each core wire includes a cylindrical conductive core. The surface of the outer body of the core is covered with an inner insulating layer, and the outer surface of the inner insulating layer is covered with a copper wire mesh twisted together by bundles.

Further, the conductive cell is a copper conductor.

Further, the conductive electric core is a conductor formed by twisting two or more single copper wires.

Further, the mica tape is one of muscovite mica tape, phlogopite mica tape or synthetic mica tape.

Further, the outer insulating layer is one of PU insulating layer or polyether ether ketone insulating layer.

Further, the thickness of the outer insulating layer is greater than that of the inner insulating layer.

Further, the copper wire mesh is integrally covered on the outer body surface of the six core wires.

The beneficial effects of the utility model are as follows: the utility model is equipped with a copper wire mesh and an aluminum foil strip, which greatly improves the shielding performance, and the fireproof coating and the mica tape improve the fireproof performance of the wire, and the setting of the bundled twisted joint also improves the shielding performance. The bending performance of the wire, the whole wire has good shielding performance, bending performance and good fire resistance performance, and can be well used in automobiles.
