For convenient use, adapters are needed to convert them to meet normal operating requirements. Furthermore, to ensure the safety of special electrical uses, overload protectors need to be added to the electrical circuit. However, due to the structural design of RVs, restarting these overload protectors after a power outage is difficult.

[0003] To facilitate the assembly and operation of the converter, the existing converter needs to be structurally improved. Utility Model Content

[0004] The present invention aims to overcome the shortcomings of existing devices, such as inconvenient assembly and poor performance, and provides a converter with overload protection that is simple and convenient to assemble and operate, and has good performance.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a converter with overload protection, comprising: The outer casing has an upper insertion hole on its top and a lower plug on its bottom. An upper mounting block is installed at the upper end of the housing, and a copper insert is connected inside the upper mounting block, the copper insert corresponding to the upper insert. A lower mounting block is installed at the lower end of the housing, and a lower plug is inserted into the lower mounting block; An overload protection element is installed in the middle of the housing and is connected to the socket copper plate and the lower plug via a conductive wire.

[0006] This converter includes a housing, an upper mounting block, a lower mounting block, and an overload protection element. The housing is a cylindrical structure composed of two separate parts. An upper insertion hole is located at the top of the housing, and a lower plug is located at the bottom. The upper insertion hole and lower plug are used for connection and conversion. The upper mounting block is fitted onto the upper end of the housing, and the lower mounting block is fitted onto the lower end. A copper socket is inserted into the upper mounting block, corresponding to the upper insertion hole, allowing the external plug to contact the copper socket and form a circuit. The lower plug is fixedly inserted into the lower mounting block and extends out of the lower end of the housing. This structure is used to connect to a socket, achieving conversion through this connection method. Simultaneously, the overload protection element is installed in the middle of the housing. A conductive wire connects the overload protection element to the copper socket and the lower plug, enabling the overload protection element to function. This converter has a simple component structure, is easy to assemble and operate, and results in good performance.

[0007] Preferably, the outer wall of the housing is provided with several anti-slip protrusions. These anti-slip protrusions facilitate plugging and unplugging of the converter, improving its usability.
