Description: As a carrier for connecting electrical parts, the high-voltage harness has different lengths, directions and positions in the car. Therefore, when fixing it, the surrounding environment should be considered, and different fixing parts and fixing methods should be selected. At the same time, the wire diameter of the high-voltage cable is relatively thick, and the tension required for fixing is relatively large. Bolts are usually used for fixing, and the main parts used are clamps and brackets.
High-voltage connection method: The connection method of high-voltage gas parts depends on the electrical parts end, and high-voltage connector connection and bolt connection are usually used.
Shielding treatment: Shielding treatment is crucial for the high-voltage electrical system of the whole vehicle. Therefore, the high-voltage harness needs to be considered according to the shielding requirements of the high-voltage electrical system of the whole vehicle at the beginning of the design. Use cables and connectors with shielding layers as much as possible, and ensure effective contact between the cable and the connector shielding layer during harness processing to ensure the integrity and effectiveness of the shielding.
Cable detection: High-voltage harness products determine specific detection standards and experimental methods according to different components. It is mainly divided into electrical detection and non-electrical detection.
Of course, electrical tests include voltage resistance, current resistance, voltage drop, insulation resistance, etc.; non-electrical tests include high and low temperature, aging, hot and cold shock, salt spray, vibration, waterproof, flame retardant, airtightness, terminal pull-out force, etc.
The specific test items should be determined according to the selection of wiring harness connection method and the requirements of the whole vehicle to ensure that the selected experiment is reasonable and avoid unnecessary waste. The experimental methods and standards can refer to the national standard.
As an important connection part of hybrid vehicles, the reliability and safety of high-voltage wiring harnesses are crucial to the safety of the whole vehicle. Therefore, when selecting cables, full consideration should be given to the selection of parts to avoid design interference. At the same time, when selecting cables and fixing and protecting materials, the weight of the wiring harness should be considered to reduce the weight as much as possible and save costs.
