Background Art

[0003] In the prior art, in order to charge the battery pack of a new - energy electric vehicle, it is necessary to install a charging dock suitable for fitting into the charging gun of the new - energy electric vehicle. To improve the charging speed, it is necessary to increase the charging current. Currently, the charging current is about 600A, and in the future, it may increase to 1000A or more. When a large current flows through the charging terminals in the charging dock, a large amount of heat is generated, and the temperature of the charging terminals in the charging dock may rise rapidly. If the temperature rise cannot be controlled in a timely manner, there is a risk of safety accidents such as burning of the charging dock or other electrical equipment.

[0004] In the prior art, in order to control the temperature rise of the charging terminals, usually, a lead frame is installed on the charging dock, and a temperature detector is attached to the lead frame. The temperature detector includes a temperature sensor and a heat pad wound around the outside of the temperature sensor. The heat pad is in thermal contact with the charging terminals, and the temperature sensor is electrically connected to the lead frame. The existing mounting structure of the temperature detector is very complex, costly, and inconvenient to use.
