AI Technical Summary
Existing automotive signal cables have poor shielding performance, and using multiple shielding layers would increase cable diameter and manufacturing costs.
The cable employs a double-layer shielding structure, in which both the first and second shielding layers consist of a shielding tape body, an inner extension, an outer extension, and a folded section. The inner and outer extensions overlap each other, and the outer extension has a folded section on its outer side. Combined with polyester wrapping tape and aluminum foil layer materials, it achieves a shielding effect of more than two layers without increasing the cable diameter.
This improves the shielding effect of the cable while essentially not increasing the cable diameter, thus reducing manufacturing costs.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of integrated wire technology, specifically an automotive signal integrated wire. Background Technology
[0002] With the development of technology, automobiles are becoming increasingly functional, and electronic control technology is being used more extensively, resulting in a greater demand for wiring inside vehicles. The wiring harnesses required for automotive wiring are now thicker and heavier than before, leading to a reduction in the space available for wiring within the vehicle.
[0003] Existing automotive signal cables use a shielding layer to shield against electromagnetic interference. However, current technology with a single shielding layer provides poor shielding, while using multiple shielding layers increases the cable diameter and manufacturing cost. Therefore, we propose an integrated automotive signal cable. Utility Model Content

[0006] Preferably, the first shielding layer and the second shielding layer have the same structure. Both the first shielding layer and the second shielding layer are composed of a shielding strip body, an inner extension, an outer extension, and a folded part. One end of the shielding strip body is provided with an inner extension, and the other end of the shielding strip body is provided with an outer extension. The inner extension and the outer extension overlap each other, and a folded part is provided on the outer side of the outer extension.
[0007] Preferably, both the first shielding layer and the second shielding layer are made of aluminum foil or metal braid.
[0008] Preferably, the filler strip is made of rubber and has a circular cross-section.

[0010] Preferably, the insulation layer is made of polyvinyl chloride (PVC) insulation layer, and the outer sheath is made of PVC sheath.
[0011] Compared with the prior art, the beneficial effects of this utility model are:

The shielding strip body has an inner extension at one end and an outer extension at the other end. The inner and outer extensions overlap each other, and a folded section is provided on the outer side of the outer extension. Although a shielding layer on one side is used, a shielding effect of more than two layers is achieved, which improves the shielding effect without increasing the diameter of the cable.

The outer extension 43 has a folded part 44 on its outer side. Although only one shielding layer is used, the shielding effect of more than two layers is achieved. While improving the shielding effect, the diameter of the cable is basically not increased.
