Several types of failure of automobile harness
Wire harness It is mainly composed of wires, terminals, connectors, packaging, nails, slot frames, etc. due to the composition of irregular parts, harness manufacturing is a low automation and labor-intensive industry. Many manual operations affect the standardization of harness. The faults in the process of harness manufacturing are random and uncontrollable.
1. Automobile assembly failure.
Wire harness The cloth on the real car,Wire harness The arrangement on the real vehicle will be dispersed into multiple parts, so as to improve the assembly type and maintainability. However, at the same time, the increase of harness interfaces and positioning parts means that the possibility of failure increases. This part classifies and summarizes the failure cases in the whole vehicle assembly process to improve the reliability of harness assembly.
2. Fixed fault.
It means that the positioning part of the harness itself falls off at the fixing hole or tie. This failure will not affect the function or the use of the whole vehicle.
Function failure is a serious failure mode, which will lead to the loss of a function of the whole vehicle and seriously affect the driving of the vehicle and the safety of the driver.
3. Appearance failure.
It is a fault form that affects customer perception. Most harnesses are arranged in areas that are not suitable for customers to perceive, but the process or space of the harness supplier will affect the assembly of parts attached to the harness, resulting in matching or aesthetic problems.
For such problems, in the preliminary design, it is necessary to consider whether there is interference risk between the wire harness or plug motion envelope area and the surrounding components, so as to select an appropriate position to arrange the fixed points to ensure the beauty on the premise of meeting the function.
4. Durability failure.
Durability failure is a failure mode formed in the middle link with the use of vehicles. It occurs randomly with the life cycle of vehicles and has unpredictable performance. Once it fails, it will cause great complaints from customers about the brand. This kind of fault mostly occurs in the envelope area of moving parts, occurs after a certain wear, and is difficult to detect in the initial stage.
