Description

Technical Field

[0001] The utility model relates to the technical field of wire harnesses, in particular to an anti-displacement wire harness with a fixing structure. Background Art

[0002] Anti-displacement harnesses usually refer to electrical harnesses used in equipment or systems. Their main purpose is to prevent the harnesses from shifting or misaligning during use, thereby ensuring that the connecting wires or conductors inside the harness are arranged in an orderly manner without causing crossover, short circuit or other adverse effects. The design and installation of anti-displacement harnesses are very important for the reliability and safety of the equipment.

[0003] However, most traditional anti-displacement harnesses lack a fixed support structure, which makes them more susceptible to external vibration and tension, causing the harness to shift or deform. During vibration or movement, the wires in the harness may collide or squeeze each other, causing the wires to shift or break.
