Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle charging connector technology, and discloses a novel Mode 2 charging gun. Background Technology

[0002] Currently, the charging guns used in the market have shortcomings in terms of size, number of parts, and connection methods. In terms of size, the PCBA boards of the charging guns used in the market are too large, resulting in high volume and cost. In addition, the finished products have many parts, making installation cumbersome and the connection method complicated. Typically, the PE pin is connected to the micro switch by crimping, which is inconvenient for subsequent assembly.

[0003] For example, Chinese utility model patent application CN210706932U discloses a novel charging gun, including a charging gun, a charging head, and a charging cable. The charging gun has a hook inside, and a handle and a button on its surface. The button passes through the charging gun and is connected to the end of the hook. The handle is located at the end of the charging gun furthest from the charging head. A mechanical lock is provided on one side of the outer surface of the charging gun. This charging gun has an anti-theft function, a simple structure, and is convenient and quick to use, improving the security of the device. Locking and unlocking the charging gun effectively prevents theft.

[0004] However, the aforementioned patents have the following drawbacks: the traditional mode 2 charging gun has a control box, which makes the overall size too large and the weight too heavy, making it inconvenient to carry, and the manufacturing cost is high. The PE pin welding can easily cause the micro switch connection to fall off later, making subsequent assembly inconvenient. Utility Model Content
