Description

Technical Field

[0001] This invention relates to a charging dock and a method for assembling the charging dock. 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. In existing technologies, to control the temperature rise of the power terminals, a lead frame is typically installed in the charging socket, and a temperature terminal detection module is integrated on the lead frame. This temperature terminal 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. Furthermore, in existing technologies, to detect the electrical signals of the signal terminals of the charging socket, flexible terminals for electrical contact with the signal terminals are also installed on the lead frame.

[0003] 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, to facilitate the installation of the lead frame, existing charging dock housings require a split design. They typically consist of a main body and a rear cover assembled to the rear port of the main body. This not only complicates the charging dock housing structure but also necessitates the addition of a waterproof sealing ring.

[0004] In the prior art, in order to lock the terminals in the charging housing, a locking part needs to be provided on the lead frame. This locking part can rotate relative to the charging housing between the locked position of the locked terminals and the unlocked position of the unlocked terminals. This makes the lead frame and the charging housing more complex, more difficult to assemble, and more expensive.

[0005] In existing technologies, an interference fit is used between the thermal pad and the power terminal to ensure reliable thermal contact. This causes the power terminal to rub against the thermal pad during insertion and removal, which may damage the thermal pad. Furthermore, in existing technologies, the contact area between the power terminal and the thermal pad is axially spaced by a predetermined distance from the solder end of the power terminal. This increases the axial length of the power terminal and makes it impossible to detect the temperature of the solder end of the power terminal in a timely and accurate manner.
