Description

Technical Field

[0001] This utility model relates to the field of charging gun technology, and in particular to a charging gun with a pluggable and replaceable connector. Background Technology

[0002] Charging guns are divided into DC guns and AC guns. DC guns, which are high-current, high-power charging guns, are generally equipped in fast-charging stations for new energy vehicles. Home use typically involves AC charging piles or portable charging guns. There are many types of charging guns. Although the existing charging guns are relatively well-designed, they still have certain shortcomings. In use, existing charging guns are limited to one model, making it difficult to replace the connectors according to usage needs. This narrows the applicability of the equipment and reduces its practicality. At the same time, most existing replacement connectors use a plug-in method for replacement, without a snap-fit ​​locking mechanism, which reduces the stability of the plug-in connection.
