[0028] like Figure 1As shown, the utility model discloses a replaceable plug 1 of a charger, wherein the plug 1 is used to match a charger body 2, the charger body 2 and the plug 1 are detachable and matched, and the charger body 2 can be replaced with different plugs 1 according to the use environment.

[0029] In this application, the plug 1 can be a plug of different specifications and standards such as Chinese, British, American, European, and Australian. Different plugs 1 can be added according to the use environment or demand requirements to improve the practicality of the device. At the same time, the charger body 2 mentioned in this application only needs to be able to match with the plug 1. The specific model, shape, and matching products of the charger body 2 will not be limited here.

[0030] like Figure 2 、 Figure 3 and Figure 5 As shown, specifically, the plug 1 matches the charger body 2, and the plug 1 includes a main body 11, a pin 12 is fixedly provided on one side of the main body 11, and a mounting protrusion 13 is provided on the other side of the main body 11, and a clamping piece 14, a button 15 and a first power connection part 16 are slidably provided on the mounting protrusion 13, and the pin 12 is electrically connected to the first power connection part 16; a mounting groove 21 is provided on the charger body 2, and a second power connection part 23 and a clamping slot 22 are provided in the mounting groove 21, and the mounting protrusion 13 slides into the mounting groove 21 so that the second power connection part 23 is electrically connected to the first power connection part 16, and the clamping piece 14 partially extends out of the mounting protrusion 13 and is engaged with the clamping slot 22 to lock the plug 1 to the charger body 2; the button 15 drives the clamping piece 14 to disengage from the clamping slot 22 to unlock the plug 1 from the charger body 2. In the present application, when the plug 1 is installed with the charger body 2, the portion of the clip 14 extending from the mounting protrusion 13 extends into the clip slot 22, securing the plug 1 and the charger body 2 together. Simultaneously, the second power connection portion 23 is electrically connected to the pin 12 via the first power connection portion 16. At this point, the charger body 2 can be connected to a socket via the plug 1. When the plug 1 needs to be removed or replaced, the button 15 is pressed, which moves the clip 14, disengaging it from the clip slot 22. The plug 1 can then be removed from the charger body 2, making the operation simple.

[0031] Furthermore, the main body 11 includes a bottom shell 111 and a top plate 112. The bottom shell 111 and the top plate 112 are fixedly connected to form the main body 11 having a mounting cavity 113. The pin 12 is fixed to the surface of the bottom shell 111 away from the top plate 112; the mounting protrusion 13 is provided on the top plate 112. A T-shaped positioning protrusion 17 is provided on the top plate 112, and a T-shaped positioning groove 24 is provided in the mounting groove 21. When the mounting protrusion 13 extends into the mounting groove 21, the T-shaped positioning protrusion 17 is positioned and matched with the T-shaped positioning groove 24. When the plug 1 needs to be matched with the charger body 2, the plug 1 slides relative to the charger body 2, so that the mounting protrusion 13 extends into the mounting groove 21. At this time, the T-shaped positioning protrusion 17 extends into the T-shaped positioning groove 24, thereby improving the stability of the connection between the plug 1 and the charger body 2.

[0032] The mounting protrusion 13 is located at the edge of the main body 11 , and the mounting groove 21 is a notch groove at the edge of the charger body 2 .

[0033] like Figure 3 Until Figure 6As shown, further, one end of the clip 14 extends into the mounting protrusion 13 and cooperates with the mounting protrusion 13 through the first spring 141, and the other end of the clip 14 can extend out of the mounting protrusion 13, and the first spring 141 applies elastic force to the clip 14 to make it extend out of the mounting protrusion 13; the button 15 slides with the mounting protrusion 13 and the button 15 can drive the clip 14 to fully extend into the mounting protrusion 13. The first end of the button 15 extends into the mounting protrusion 13 and cooperates with the mounting protrusion 13 through the second spring 151. The second end of the button 15 extends out of the mounting protrusion 13. The first end of the button 15 is provided with a driving inclined surface 152. The clamping member 14 is provided with a driving protrusion 142. The button 15 can drive the driving protrusion 142 through the driving inclined surface 152 to drive the clamping member 14 to move in the direction of extending into the mounting protrusion 13; the second spring 151 applies an elastic force to the button 15 to reset it. When the plug 1 is mated with the charger body 2, the first spring 141 applies elastic force to the snap-fit ​​member 14, so that the portion of the snap-fit ​​member 14 extending out of the mounting protrusion 13 extends into the slot 22, thereby fixing the plug 1 and the charger body 2 together; when it is necessary to remove the plug 1 from the charger body 2, the second end of the button 15 is pressed, and an external force is applied to the button 15, so that the button 15 moves in the direction of extending into the mounting protrusion 13. At this time, the driving inclined surface 152 applies force to the driving protrusion 142, and the driving protrusion 142 drives the snap-fit ​​member 14 to move, so that the snap-fit ​​member 14 disengages from the slot 22. At this time, the snap-fit ​​member 14 no longer locks the plug 1 and the charger body 2 together, and the plug 1 can be removed from the charger body 2. When no external force is applied to the button 15 , the second spring 151 drives the button 15 to reset, and the first spring 141 drives the clamping member 14 to reset. At the same time, when the clamping member 14 is reset, the driving protrusion 142 can act on the driving inclined surface 152 and apply force to the button 15 to reset it.

[0034] Furthermore, the plug pin 12 includes a plug-in portion 121 and a spring 122, the plug-in portion 121 extends out of the bottom shell 111, the spring 122 is arranged in the installation cavity 113, the first power connection portion 16 is a slot, and the spring 122 is partially located in the slot; when the mounting protrusion 13 is installed in the mounting groove 21, the second power connection portion 23 extends into the slot and contacts the spring 122, so that the charger body 2 is electrically connected to the pin 12 on the plug 1, and when the plug 1 is matched with the socket, the charger body 2 can be powered.

[0035] In one embodiment, there are two pins 12, which are used to connect the live wire and the neutral wire respectively; the number of the first power connection parts 16 and the number of the second power connection parts 23 are respectively two, and correspond to the corresponding pins 12 according to the phase.

[0036] In another embodiment, there are three pins 12 , and the three pins 12 are used to correspond to the live wire, the neutral wire, and the power supply, respectively.

[0037] The present invention can be implemented in various ways and modified without departing from the broad spirit and scope of the present invention. The above-mentioned embodiments are used to illustrate the present invention, but do not limit the scope of the present invention.
