According to the high-voltage connector and the vehicle-mounted charger, a plurality of insertion pieces are arranged in a first shell, and contact pieces corresponding to the insertion pieces are arranged in a second shell; a first conductive piece is also arranged in the first shell and is connected with a plurality of first thermistors which are arranged in parallel; a second conductive piece is further arranged in the second shell, the second conductive piece is connected with a plurality of second thermistors which are arranged in parallel, and the first conductive piece is further connected with a control unit; when the first conductive part is jointed with the corresponding second conductive part, the first conductive part, the first thermistor, the second conductive part and the second thermistor form a conductive loop; the first thermistor and the second thermistor are arranged in parallel. The control unit can monitor whether the total resistance value of the first thermistor and the second thermistor which are connected in parallel is within the preset interval to judge whether the temperature rise of the high-voltage connector is abnormal, if yes, the output voltage is cut off, and the situation that the high-voltage connector is damaged is avoided.
本发明公开了一种高压连接器及车载充电机,包括:第一壳体内设有多个插片,第二壳体内设有与插片相对应的接触件;第一壳体内还设有第一导电件,第一导电件连接有若干个并联设置的第一热敏电阻;第二壳体内还设有第二导电件,第二导电件连接有若干个并联设置的第二热敏电阻,第一导电件还连接有控制单元;第一导电件与对应的第二导电件相接合时,第一导电件、第一热敏电阻、第二导电件和第二热敏电阻组成导电回路;第一热敏电阻和第二热敏电阻并联设置。控制单元能监控并联的第一热敏电阻和第二热敏电阻的总阻值是否处于预设区间来判断高压连接器的温升是否异常,若异常便切断输出电压,避免发生高压连接器损毁的情况。
