Description

Technical Field

[0001] The utility model relates to an automobile wiring harness with an anti-loosening structure. Background Art

[0002] The automotive wiring harness is the network body of the automotive circuit. Without the wiring harness, there would be no automotive circuit. The automotive wiring harness is mainly composed of copper connectors (plugs, sockets), plastic sheaths, wires, etc. The connectors are crimped with the wires and installed in the plastic sheath. The wires are bundled with harnesses and wrapped with tape. The common specifications of the wires in the automotive wiring harness are nominal cross-sectional area, each with an allowable load current value, and are used for wires of different power electrical equipment. The automotive wiring harness is divided from the function into two types: power lines that carry power to drive the actuators (actuators) and signal lines that transmit sensor input commands. Power lines are thick wires that carry large currents, while signal lines are thin wires that do not carry power (optical fiber communications). The wiring harness industry chain includes wires and cables, connectors, processing equipment, wiring harness manufacturing and downstream application industries. The wiring harness is widely used and can be used in automobiles, household appliances, computers and communications equipment, various electronic instruments, etc. The body wiring harness connects the entire body and is generally H-shaped.

[0003] The automotive wiring harness is an important component used for circuit connection in the car. The stable operation of the automotive wiring harness is an important guarantee for the normal use of the vehicle. When the automotive wiring harness is in use, it is easy to cause the wiring harness to be pulled during installation and maintenance as well as when the car is driving. Long-term use can easily lead to loose problems at the connection position, making it difficult to ensure the normal and stable driving of the vehicle, increasing safety hazards.
