Problems solved by technology

[0002] The off-line inspection process of the motor controller needs to connect the controller under test to the external power supply and the load motor. Since there are 5 places in the conventional wiring method of the controller that need to use bolts to connect the cables, and there are requirements for installation torque, the operation takes a long time and requires installation. The probability that the torque does not meet the standard will easily cause detection errors and is not conducive to detection. In view of this situation, the present invention proposes a test fixture for the AC motor controller of an electric vehicle, which helps to quickly and reliably connect the controller under test with the external power supply. It is connected with the load motor and has position status detection function, which can save a lot of manpower and time in the process of mass production, improve production efficiency and save costs

Abstract

An electric car AC motor controller test clamp provided by the present invention comprises a box body and a supporting plate, a cylinder is arranged at the upper part of an inner cavity of the box body, and an ejecting rod of the cylinder is connected with a positioning plate. Electrical contacts are distributed on the positioning plate, the supporting plate is in slip connection with a sliding plate, and the sliding plate is equipped with a first positioning block, a second positioning block, a buffer positioning plate and a guiding sleeve. The positioning plate is equipped with a guiding column, and the supporting plate is equipped with a limiting rod. The electric car AC motor controller test clamp of the present invention is helpful to connect a tested controller with an external powersupply and a load motor rapidly and reliably, is equipped with a position state detection function, can save a lot of manpower and time during a mass production process, enables the production efficiency to be improved, and saves the cost.
