Wire harness structure: how to prevent crushing and correct fixing method

Jan 17,2024

In the wiring industry, the design and installation of wiring harness structures are crucial. A wire harness is a comprehensive integration of connecting wires, including elements such as wires, cables, sleeves, etc., used for transmitting power, data, and signals. However, the wiring harness structure is easily affected by external environment and improper operation, leading to crushing and damage. In this article, we will discuss the reasons why wire harness structures are prone to crushing and introduce the correct fixing method to prevent such problems from occurring.
Why is the wiring harness structure prone to compression damage?
The main reasons why the wiring harness structure is prone to compression damage include:
External pressure: Without sufficient protective measures during the installation of wiring harnesses, external forces such as mechanical compression, vibration, or impact may cause the wiring harness to be under pressure, thereby damaging the wires or cables in the harness.
Improper bending radius: The wires and cables of the wiring harness usually have a minimum bending radius requirement. If the wiring harness is excessively bent or bent in an improper position, the wires and cables may be subjected to stress, resulting in damage.
Temperature changes: Temperature changes can cause expansion and contraction of the wiring harness material. If this is not taken into account, the wiring harness may be stretched or compressed, ultimately leading to damage.
Vibration and shock: In certain applications, such as automobiles, airplanes, and industrial machinery, vibration and shock are common. If the wiring harnesses are not properly fixed and buffered, they are susceptible to vibration and impact.
Correct fixing methods and protective measures
To prevent damage to the wiring harness structure, the following are some correct fixing methods and protective measures:
Use fixing clips: Use appropriate fixing clips at critical locations of the wiring harness to ensure that the harness remains in the correct position and is not affected by external pressure.
Comply with bending radius requirements: Ensure compliance with the manufacturer's minimum bending radius requirements when installing wiring harnesses to prevent stress on wires and cables.
Use appropriate protective sleeves: For wiring harnesses used in harsh environments, consider using protective sleeves to provide additional protection and protection.
Vibration and impact protection: In vibration and impact environments, use seismic protection fixtures and suspension systems to reduce the vibration and impact on the wiring harness.
Regular inspection and maintenance: Conduct regular wiring harness inspections to ensure that the wiring harness is still safe and not crushed or otherwise damaged.

The low voltage resistance of the wiring harness comprehensive tester is insufficient

1. Wire quality issues Low voltage resistance testing may be affected by wire quality. If there are problems such as poor welding, breakage, or substandard material quality in the manufacturing process of wires, it can lead to an increase in low-voltage resistance. At this point, visual inspection and testing of the wires are required to confirm if there are any issues. If there are any issues, the wires need to be remanufactured or replaced.
