Description

Technical Field

[0001] This invention relates to the field of electric vehicle charging technology, and more particularly to a temperature detection module and a charging socket including the temperature detection module. Background Technology

[0002] In existing technologies, charging the battery packs of new energy electric vehicles requires installing charging sockets suitable for use with charging guns. To increase charging speed, the charging current needs to be increased, currently reaching 600A, and potentially even 1000A in the future. When a large current flows through the power terminals within the charging socket, it generates a significant amount of heat, causing a rapid rise in the temperature of the power terminals. If this temperature rise is not controlled in time, it can lead to safety accidents, such as burning out the charging socket or other electrical equipment.

[0003] In existing technologies, to control the temperature rise of the power terminals, a lead frame is typically installed in the charging dock, and a temperature detection module is integrated on the lead frame. This temperature detection module includes a temperature sensor and a thermally conductive pad surrounding the temperature sensor. The thermally conductive pad is in thermal contact with the power terminals, and the temperature sensor is electrically connected to the lead frame. However, in existing technologies, the lead frame is bulky and needs to be pre-installed in the charging dock housing, making it very inconvenient to use. Furthermore, in existing technologies, to facilitate the installation of the lead frame, the charging dock housing needs to adopt a split design, which results in a complex charging dock housing structure. In addition, existing lead frames need to be able to rotate between the locked position and the unlocked position of the power terminals, which makes the lead frame and charging dock housing more complex, assembly more difficult, and costs higher.
