Durability test fixture for high-voltage direct-current contactor

Abstract

The utility model provides a high voltage DC contactor endurance test clamp comprising a support plate, a third slide block and a second slide bar are arranged on the lower part of a third fixing plate, and a fourth slide block, a fifth fixing plate and a third slide bar are arranged on the lower part of a fourth fixing plate. According to the durability test fixture for the high-voltage direct-current contactor, a motor drives a fifth sliding block and a sixth sliding block to move on a fourth sliding rod, so that an upper fixture and a lower fixture perform clamping according to the thickness of equipment through the movement of the fifth sliding block and the sixth sliding block, and the situation that when the equipment is clamped, the equipment is damaged is avoided. As the test result is inaccurate or the test is interrupted due to poor contact between the clamp and the tested equipment, the fifth sliding block and the sixth sliding block are driven by the motor to move, the clamping force of the upper clamp and the lower clamp on the tested equipment is improved, the poor contact phenomenon is effectively avoided, and the test efficiency is improved. Therefore, the durability and the practicability of the clamp for clamping the tested equipment are improved.
