In order to improve the charging speed, need to improve the charging current, and the current charging current is as high as 600A, and will even increase to 1000A in the future. When the large current flows through the power terminal in the charging seat, a large amount of heat will be generated, which will cause the temperature of the power terminal in the charging seat to rise sharply, and if the temperature rise cannot be controlled in time, it will cause safety accidents, for example, the charging seat or other electrical equipment will be burned out.

[0003] In the prior art, in order to control the temperature rise of the power terminal, a lead frame is usually arranged in the charging seat, and a temperature detection module is integrated on the lead frame. The temperature detection module includes a temperature sensor and a heat-conducting pad wrapped outside the temperature sensor. The heat-conducting pad is in thermal contact with the power terminal, and the temperature sensor is electrically connected with the lead frame. However, in the prior art, the lead frame is relatively large in size, and needs to be pre-installed in the charging seat shell, which is very inconvenient to use. In addition, in the prior art, in order to facilitate the installation of the lead frame, the charging seat shell needs to be designed in a split type, which leads to a complex structure of the charging seat shell. In addition, the existing lead frame needs to be able to rotate between a locking position for locking the power terminal and an unlocking position for unlocking the power terminal, which will make the lead frame and the charging seat shell more complex, more difficult to assemble and higher in cost.
