Description

Technical Field

[0001] The utility model relates to the technical field of power converters, in particular to a foldable plug of a power converter. Background Art

[0002] A foldable plug for a power converter is a power adapter or converter with integrated foldable pins designed to improve portability and flexibility of use. A foldable plug is a specially designed power interface accessory, which features a metal pin that can be folded and stored inside the plug body through a built-in mechanical structure. This design not only reduces the space occupied during storage, but also avoids damage to the pins during transportation, while also protecting other luggage items from scratches.

[0003] During use, the folding plug on the existing power converter is moved out of the power converter from a vertical state to a horizontal state. At this time, the plug base has a certain self-locking property due to friction or the cooperation between teeth and grooves. However, when the plug is plugged into an external power socket, the resistance encountered causes axial rotation between the plug base and the power converter, which can easily cause electric shock caused by contact between fingers and the plug, which is not conducive to safe use.

[0004] Therefore, the utility model provides a foldable plug of a power converter to solve the above problems. Utility Model Content

[0015] (III) Beneficial effects

[0016] The present application utilizes the cooperation between the card plate and the plug slot to fix the position of the hinged seat and the plug that are transformed from a vertical state to a horizontal state, thereby preventing the hinged seat from rotating axially due to resistance when the plug is plugged into an external power socket, causing fingers to come into contact with the plug and cause electric shock, thereby ensuring the safety of the power converter body.
