[0001] The utility model belongs to the technical field of automobile wiring harnesses, and in particular relates to a wiring harness component which is easy to install. Background Art

[0002] The car wiring harness runs through the entire car. It connects various electrical devices in the car and acts as a medium for power supply and signal transmission of each device.

[0003] The automotive wiring harness is often compared to the neural network system of the car. The automotive wiring harness is the network body of the car circuit. Without the wiring harness, there is no car circuit. The literal meaning of wiring harness is the bundled object of wires. The automotive wiring harness defines the use environment of the wiring harness, that is, the assembly of the car.

[0004] However, there are some problems with the existing technology: the existing automotive wiring harnesses are all bonded by tape when in use, and the tape is prone to falling off during use, which makes the installation of the wiring harness very unstable. In addition, the wiring harness is usually relatively long when in use. The existing technology is to bundle the wiring harness with a strapping tape, or to bend the wiring for bonding, which can easily cause damage to the wiring harness. Therefore, we propose a wiring harness assembly that is easy to install. Utility Model Content
