Description

Technical Field

[0001] The present invention relates to an electrical connector assembly and a charging device including the electrical connector assembly.

Background Art

[0002] In the prior art, in order to charge the battery pack of a new energy electric vehicle, it is necessary to attach a charging stand suitable for pairing with a charging gun to the new energy electric vehicle. In order to improve the charging speed, it is necessary to increase the charging current, which currently reaches a maximum of 600 A and may be increased to 1000 A in the future. When a large current flows through the charging terminal in the charging stand, a large amount of heat is generated, causing a rapid temperature rise of the charging terminal in the charging stand. If the temperature rise cannot be controlled in a timely manner, it may cause a safety accident such as burning out the charging stand or other electrical equipment.

[0003] In the prior art, in order to control the temperature rise of the charging terminal, usually, one lead frame is provided in the charging stand, and a temperature detection module is attached to the lead frame. The temperature detection module includes a temperature sensor and a heat conduction pad coated outside the temperature sensor. The heat conduction pad is in thermal contact with the charging terminal, and the temperature sensor is electrically connected to the lead frame. In the prior art, the heat conduction pad on the lead frame can only be in thermal contact with the outside of the cylindrical body of the charging terminal and cannot be in thermal contact with the connection end electrically connected to the cable of the charging terminal, thereby making it impossible for the temperature detection module to detect the temperature of the charging terminal in a timely and accurate manner, reducing the accuracy and time responsiveness of temperature detection. Also, the cost of such a conventional temperature detection solution is high.

[0040] As shown in Figures 1 to 10, in the illustrated embodiment, the heat conduction member 42 is columnar in shape and has a mounting hole 402, and the body 410 of the temperature sensor 41 is inserted into the mounting hole 402 of the heat conduction member 42 and is tightly fitted to the inner wall surface of the mounting hole 402 so as to be in close contact with the inner wall surface of the mounting hole 402.
