[0026] Example 1: See Figures 1 to 6 The present embodiment provides a converter with a rotary plug structure, which includes a rotary plug structure, a conversion seat 1 and a conversion terminal 2. The rotary plug structure includes a shell 3, a pin 4, a rotating seat 5, a sliding contact piece 6, an elastic component 7 and a fixed seat 8. The rotating seat 5 is rotatably arranged on the shell 3. Specifically, the shell 3 is provided with a rotating hole, and the lower part of the rotating seat 5 passes through the rotating hole and is provided with a flange that can be snapped on the edge of the rotating hole. The pin 4 is fixedly arranged on the rotating seat 5, and the end portion extends into the shell 3 to form a contact end 41. The fixed seat 8 is arranged on the shell 3 corresponding to the position of the rotating seat 5. Preferably, a rotating shaft 51 is provided at the center position of the bottom surface of the rotating seat 5, and an axial hole 81 adapted to the rotating shaft 51 is provided on the fixed seat 8, so that the rotation of the rotating seat 5 is more stable.

[0027] The position of the sliding contact piece 6 corresponding to the contact end 41 is set on the fixed seat 8. Specifically, a lifting cavity 82 adapted to the shape of the sliding contact piece 6 is provided on the fixed seat 8, and the opening of the lifting cavity 82 is provided with a stopper 83 that can confine the sliding contact piece 6 therein, which has a good limiting effect on the sliding contact piece 6, so that the sliding contact piece 6 can only move up and down in the lifting cavity 82.

[0028] The elastic member 7 is located on the fixing seat 8 and pushes the sliding contact piece 6 to move toward the contact end 41 and to be in close contact with it. Preferably, a mounting groove 84 for mounting the elastic member 7 is provided on the bottom surface of the lifting chamber 82, which facilitates the rapid positioning and mounting of the elastic member 7 and is not easily displaced.

[0029] The conversion seat 1 is arranged on the housing 3, and the conversion terminal 2 is arranged on the conversion seat 1 and connected to the sliding contact piece 6. In this embodiment, it is preferred that a connecting piece 21 extending to the bottom of the mounting groove 84 is provided at one end of the conversion terminal 2, and the conversion terminal 2 and the connecting piece 21 are an integral connection structure, both of which are conductive metals. The elastic component 7 is a metal spring, one end of which is in electrical contact with the sliding contact piece 6, and the other end is in electrical contact with the connecting piece 21, that is, the conversion terminal 2 is directly in contact with the sliding contact piece 6 through the metal spring, which ensures the stability and reliability of the electrical connection, and also improves the durability of the converter. In other embodiments, the conversion terminal 2 may also not be provided with a connecting piece 21, but directly connected to the sliding contact piece 6 through a conductive wire. At this time, there is no requirement for the material of the elastic component 7, and it can be a spring rubber column or a metal spring or other components with elastic materials.

[0030] In this embodiment, the sliding contact piece 6 is preferably in an arc shape, which ensures that the track of the adapted contact end 41 during rotation is followed, reduces the material used, reduces the cost, reduces the volume, and reduces the occupied space. Preferably, a limiting groove 61 adapted to the contact end 41 is provided on the sliding contact piece 6, and when the contact end 41 slides to the limiting groove 61, it has a stuck positioning effect, prompting that the rotation is in place.

[0031] Example 2: See Figures 7 to 10The present embodiment provides a converter with a rotating plug structure, which is basically the same as the embodiment 1, except that: the plug pin 4 adopts a flip structure design. Specifically, the rotating seat 5 includes an upper shell 51, a base 52 and a rotating shaft seat 53. The upper shell 51 and the base 52 are buckled to form a rotating cavity for installing the rotating shaft seat 53. The plug pin 4 is fixed on the rotating shaft seat 53. The upper shell 51 is provided with an upper avoidance groove 511 for allowing the plug pin 4 to rotate with the rotating shaft seat 53. The base 52 is provided with a lower avoidance groove 521 for allowing the contact end 41 to rotate with the rotating shaft seat 53. The design of the upper avoidance groove 511 and the lower avoidance groove 521 allows the plug pin 4 to be conveniently and smoothly flipped and retracted. When not in use, the plug pin 4 is pushed to flip toward one side of the upper avoidance groove 511, so that the plug pin 4 is retracted into the upper avoidance groove 511, which reduces space and is convenient for storage.

[0032] Embodiment 3: This embodiment provides a rotary plug structure, which is basically the same as Embodiment 1, except that it does not include a conversion seat 1 and a conversion terminal 2, and the power cord extends into the housing 3 and is directly connected to the sliding contact piece 6.

[0033] Embodiment 4: This embodiment provides a rotary plug structure, which is basically the same as Embodiment 2, except that it does not include a conversion seat 1 and a conversion terminal 2, and the power cord extends into the housing 3 and is directly connected to the sliding contact piece 6.
