Description

Technical Field

[0001] The utility model relates to the field of automobile wiring harnesses, in particular to a concave bracket for fixing automobile chassis wiring harnesses. Background Art

[0002] Wire harness brackets are a relatively common wire harness support structure in automobiles. They are mainly used in the engine compartment and passenger compartment of vehicles to support and fix cable harnesses and connectors. As automobile development moves towards electric intelligence, the tolerance requirements and surface appearance quality requirements of parts are also increasing. When uneven surface shrinkage causes significant internal stress or deformation in the product, it is not enough to meet quality requirements or cost requirements, and the workpiece usually has multiple quality problems. In order to meet environmental regulations, production costs, and strict quality requirements, automobile manufacturers focus on lightweighting automobile parts. Lightweighting of automobiles has become a development trend in the global automobile industry. In the past, cable ties or velvet wrapping methods were used to fix the wire harnesses. However, the above bundling methods also have disadvantages. Since the internal temperature of the vehicle may be too high when running at high speeds, bundling or wrapping fixation is easy to loosen, and it cannot provide safety, stability and protection for the signal transmission of the wire harness.
