[0002] The present invention relates to connectors, and more particularly to low voltage signal connectors for controlling the power on and power off of power terminals of high voltage power connectors. [Background technology]

[0003] In the prior art, for safety reasons, it is desirable to disconnect the power supply to the high-voltage power terminal during the process of tightening or loosening the high-voltage power terminal of the high-voltage power connector. Therefore, in the prior art, a low-voltage signal connector for controlling the power-on and power-off of the high-voltage power terminal is generally incorporated into the high-voltage power connector, and the low-voltage signal connector is generally called a high-voltage interlock connector. During the process of tightening or loosening the high-voltage power terminal, the low-voltage signal connector is electrically disconnected from the mating signal connector, thereby turning off the power supply to the high-voltage power terminal. After the high-voltage power terminal is tightened to the mating power terminal, the low-voltage signal connector is electrically connected to the mating signal connector, thereby turning on the power supply to the high-voltage power terminal.

[0004] In the prior art, the position of the low-voltage signal connector in the high-voltage power connector is fixed and cannot float relative to the housing of the high-voltage power connector, so that the low-voltage signal connector cannot absorb installation errors and manufacturing errors, which therefore causes great difficulties in the mating operation of the low-voltage signal connector.
