Description

Technical Field

[0001] The utility model belongs to the technical field of automobile floor cables, and in particular relates to a novel automobile floor cable. Background Art

[0002] Automotive floor cables are a crucial component of the vehicle wiring harness system. They connect electronic components beneath the vehicle floor, ensuring the smooth flow of electricity and the accurate transmission of information. They typically consist of cables, wrapping material, and connectors (terminals). Cables, comprising the largest portion of automotive floor cables, are primarily made from multi-core copper wire. Wrapping material protects the cables. Common wrapping materials include corrugated tubing, cloth-based tape, flannel tape, PVC tubing, and sponge strips. Connectors connect the cables to electronic components, ensuring smooth current flow.

[0003] Existing automotive floor cables often use electronic wires, which are heavy and expensive. FFC, also known as flexible flat cable, is a type of cable made of flat and flexible conductors (usually tinned pure copper wire) bonded together at high temperatures. It is lightweight and low-cost. Therefore, how to apply FFC to automotive floor cables to achieve vehicle weight reduction is a pressing issue. Utility Model Content
