Description

Technical field [0001] The present invention relates to an electrical flat conductor for motor vehicles. The flat conductor has a flat conductor core composed of conductive flat conductor material and an insulator composed of insulating material surrounding the flat conductor core, wherein the height of the flat conductor core is less than The width of the flat conductor core. Background technique [0002] Such electrical flat conductors are used, for example, as a substitute for round conductors in the automotive industry. Due to the flat geometry of the flat conductors, these flat conductors can be used, for example, when their installation space is small, for example behind the outer layer in the interior space of a motor vehicle. [0003] This flat conductor includes a conductive flat conductor core that extends in the longitudinal direction of the flat conductor and whose height (in cross section) is smaller than its width. The flat conductor core is surrounded by an insulat...

Problems solved by technology

[0005] The problem with this forming method is that, especially when relatively soft insulating materials such as polyvinyl chloride (PVC) are used, damage to the insulation of the flat conductor can result due to the forces acting on the flat conductor.

However, this results in a longer cycle time during the bending process and thus increases the manufacturing cost of the 3D bent flat conductor

Depending on the machine load rate, this method may even require the acquisition of an additional bending unit, resulting in additional investment costs
