The wire and cable segment is called a wiring harness segment, which is an important component of products such as aircraft, automobiles, and home appliances.

[0003] Designers use clamps to fix wire harnesses in the equipment. There are multiple wire harnesses in the equipment, and there are multiple wire harnesses in the clamps, coming from different directions and going to different directions.
