Power connector and connector assembly

Abstract

The invention discloses a power connector, which comprises an insulating body with a slot formed in one side thereof, and conductive terminals arranged in the insulating body. Each conductive terminalhas an electrical contact at one end thereof, which is suitable for being in electrical contact with a bus-bar plug assembly inserted into the slot. The power connector further comprises a detectionterminal arranged in the insulating body. The detection terminal has an electrical contact at one end thereof, which is suitable for being in electrical contact with the bus-bar plug assembly insertedinto the slot. The electrical contact of the detection terminal is located at the back of the electrical contacts of the conductive terminals, so that the detection terminal electrically contacts thebus-bar plug assembly after the conductive terminals electrically contact the bus-bar plug assembly in the process in which the bus-bar plug assembly is inserted. Thus, the on/off time of a power supply system can be controlled according to the electrical connection state of the detection terminal. Therefore, electric arc between the conductive terminals and the bus-bar plug assembly is avoided during plugging and pulling of the bus-bar plug assembly, and the safety performance of the power connector is improved.

Description

technical field [0001] The invention relates to a power connector and a connector assembly including the power connector. Background technique [0002] In the prior art, a power connector generally includes an insulating body and a positive conductive terminal and a negative conductive terminal disposed in the insulating body. The positive conductive terminal and the negative conductive terminal are adapted to make electrical contact respectively with a positive bus bar and a negative bus bar inserted into the power connector. However, when plugging and unplugging with power, an arc will be generated between the positive conductive terminal and the positive bus bar and between the negative conductive terminal and the negative bus bar. When the power supply voltage is high, the high-voltage arc generated may burn the positive conductive terminal and the negative bus bar. The negative conductive terminal may cause heat fusion of the positive conductive terminal and the negati...

Problems solved by technology

However, when plugging and unplugging with power, an arc will be generated between the positive conductive terminal and the positive bus bar and between the negative conductive terminal and the negative bus bar. When the power supply voltage is high, the high-voltage arc generated may burn the positive conductive terminal and the negative bus bar. Negative conductive terminals, in severe cases, may cause thermal fusion of positive conductive terminals and negative conductive terminals, making positive conductive terminals and negative conductive terminals thermally welded with positive bus bars and negative bus bars, seriously affecting safety
