Description

Technical Field

[0001] The utility model belongs to the technical field of power sockets, and more specifically, particularly relates to a waterproof single-pole German-style output socket. Background Technique

[0002] The German-style output socket is a power socket that conforms to German standards. It usually has two cylindrical jacks and one grounding jack. This design can better adapt to German-standard plugs and ensure a tight and reliable connection between the plug and the socket.

[0003] Existing German-style output sockets usually have no corresponding waterproof structure or a low waterproof level. When used outdoors, in rainy or splashing environments, rainwater easily enters the output socket and even invades the chassis through the output socket, resulting in "burning out the machine" or electric leakage, posing a risk of fire or electric shock and having certain potential safety hazards. Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies to provide a waterproof single-pole German-style output socket, with the expectation of achieving a more practical value purpose.
