Background
With the development of new energy industry, the application of electric automobiles and energy storage devices is more and more widespread. The fixing of the signal acquisition wire harness on the high-voltage component of the battery management system affects the advantages and disadvantages of the whole battery management system. At present, when the wire harness is fixed, the wire harness is fixed on the metal plate of the vehicle body by adopting the ribbon buckle, and the mode is easy to operate and is also suitable for the rhythm of mass production and assembly of automobiles. However, the conventional band buckle adopts a mode of binding the wire harness in advance, and after binding is completed, the position of the band buckle cannot be adjusted, so that the requirement on the accuracy of the fixing position of the wire harness is extremely high. In addition, because of different vehicle types or different positions of the vehicle body of the same vehicle type, the sizes of holes (commonly used circular holes with the diameter of 6mm and circular holes with the diameter of 8 mm) for fixing the wire harness are different from each other on the metal plate of the vehicle body. This results in the fact that when the conventional tie-down buckles are used for fixing, the tie-down buckles cannot be mutually used in the fixing holes with different diameters and shapes, which necessarily results in resource waste.
In addition, some parts of the sheet metal part of the vehicle body are not provided with sheet metal holes, so that the wire harness is directly suspended in the vehicle. The sheet metal fixing part of the conventional buckle structure is directly clamped on the sheet metal of the vehicle body, and the buckle is easy to fall off due to insufficient fixing strength, so that the wire harness is suspended in the vehicle. The wire harness can interfere with peripheral components along with the shaking of the vehicle body, so that the wire harness can be worn for a long time, and even a fire disaster is caused by short circuit. Therefore, a stable and reliable wire harness fixing mode is needed, the problem of fixing the signal acquisition wire harness can be effectively solved, the safety performance of the whole battery management system is improved, the wire harness fixing device with higher universality is adopted to solve the problem of wire harness fixing, and a plurality of groups of wire harnesses are installed in a wire harness arrangement space as few as possible, so that the standardization and the universality of wire harness fixing are finished.
