Abstract

The invention provides a high-pressure wire harness leakproofness on-line testing system for vehicles. The high-pressure wire harness leakproofness on-line testing system comprises a fast detection clamp and a leakproofness detector, wherein the fast detection clamp comprises a base, a linear guide rail, a leakproof base, a leakproofness supporting base and a toggle clamp. The linear guide rail, the leakproofness supporting base and the toggle clamp are arranged on the base, the leakproofness supporting base and the toggle clamp are arranged at two ends of the linear guide rail respectively, the leakproof base is arranged on the linear guide rail and connected with the toggle clamp, an air pipe fast connector is arranged on the leakproof base and connected with the leakproofness detector through the air pipe fast connector, and the leakproofness detector can be a proper leakproofness detector sold in the market. The high-pressure wire harness leakproofness on-line testing system can effectively detect leakage rate of high-pressure wire harnesses, improves relevance ratio of bad products, greatly reduces testing time and totally meets on-line testing requirements.

Description

technical field [0001] The invention relates to the field of high-voltage electrical systems of new energy vehicles, in particular to an on-line test system for the tightness of high-voltage wiring harnesses for vehicles. Background technique [0002] The high-voltage system voltage of new energy pure electric vehicles can reach up to more than 500 volts. Due to layout and space constraints, high-voltage cables are generally arranged outside the vehicle body, and the working environment is harsh, so there are high requirements for the airtightness of high-voltage cables. The safety of new energy vehicles is an important factor affecting the development of the industry. Before they leave the factory, various tests including sealing performance tests need to be carried out on key components. [0003] At present, the sealing performance test of high-voltage cables of pure electric vehicles is mainly realized by water testing machines. However, the testing machine has low effi...
