Description

TECHNICAL FIELD

[0001] The utility model relates to an alternating current charging module and direct current charging module and the charging stand including the alternating current charging module and direct current charging module, in addition, the utility model still relates to a charging module and the charging stand including the charging module. BACKGROUND

[0002] In the prior art, in order to charge the battery pack of new energy electric vehicle, it is necessary to install the charging seat suitable for being matched with the charging gun on the new energy electric vehicle. In the prior art, the charging seat with alternating current charging and direct current charging functions usually includes a mounting bracket, a housing, alternating current power terminals and direct current power terminals. The mounting bracket is used for being fixed to the vehicle body, for example, being fixed to the vehicle body sheet metal part. The housing is fixed to the mounting bracket. The first terminal hole for inserting the alternating current power terminal and the second terminal hole for inserting the direct current power terminal are formed in the housing. In the prior art, the alternating current charging module and the direct current charging module are integrated in the same housing. Therefore, the direct current charging module and the alternating current charging module cannot be replaced separately, and the direct current charging module and the alternating current charging module must be replaced simultaneously. This will cause inconvenience and high cost.

[0003] In the prior art, in order to improve the charging speed, it is necessary to increase the charging current. At present, the charging current is as high as 600A, and in the future, it will even be increased to 1000A. When the large current flows through the power terminals in the charging seat, a large amount of heat will be generated, which will cause the temperature of the power terminals in the charging seat to rise sharply. 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. In the prior art, in order to control the temperature rise of the power terminals, a lead frame is usually arranged in the housing of the charging seat, and a terminal temperature detection module is integrated on the lead frame. In the prior art, the lead frame is large in size, and needs to be pre-installed in the charging seat housing, 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 housing needs to be designed in a split type. The existing charging seat housing usually includes a housing main body and a housing rear cover assembled to the rear port of the housing main body, which will cause the charging seat housing to be complex in structure and high in cost.
