[0036] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in detail.

[0037] The utility model embodiment provides a power adapter, such as Figures 1 to 7 As shown, the power adapter includes a housing 1, a rotating plug 2 and an electrical connection socket 3; the electrical connection socket 3 is installed in the housing 1, and the electrical connection socket 3 includes a socket 31 for electrical connection; the rotating plug 2 is rotatably installed on the housing 1, and the rotating plug 2 can be rotatably received on the housing 1 and rotatably raised from the housing 1; the rotating plug 2 includes a plug-in portion 21 for electrical connection, and the plug-in portion 21 is inserted into the housing 1 and is arranged corresponding to the socket 31. When the rotating plug 2 is rotated and raised, the plug-in portion 21 is plugged into the socket 31; when the rotating plug 2 is rotatably received on the housing 1, the plug-in portion 21 is separated from the socket 31.

[0038] The utility model provides a plug-in portion 21 on the rotating plug 2, and a socket portion 31 on the electrical connection socket 3. When the rotating plug 2 is rotated and erected, the plug-in portion 21 can be plugged into the socket portion 31 to achieve electrical connection between the two. Since the plug-in portion 21 is plugged into the socket portion 31 during connection, the connection between the two is more stable and reliable, that is, the electrical connection of the rotating plug 2 is more stable and reliable. When the rotating plug 2 is rotated and stored in the housing 1, the plug-in portion 21 is disengaged from the socket portion 31, and the plug-in portion 21 is separated from the socket portion 31. The rotating plug 2 is rotatably stored in the housing 1, and is stored and carried together with the power adapter.

[0039] Specifically, the electrical connection socket 3 can be a conductive copper sheet or the like. The power adapter also includes a main circuit board 4 and an interface circuit board 5. The main circuit board 4 is installed inside the housing 1, and the electrical connection socket 3 is electrically connected to the main circuit board 4. The interface circuit board 5 is electrically connected and plugged into the main circuit board 4. The interface circuit board 5 is provided with a charging interface 51, such as a USB-A port, a Type C port, etc. The charging interface 51 is connected to the charging cable to enable the power adapter to charge the charging object.

[0040] Furthermore, if Figure 6 and Figure 7 As shown, the socket part 31 includes two socket pieces 311 arranged opposite to each other, and the two socket pieces 311 are arranged vertically; a socket slot 312 is formed between the two socket pieces 311; when the rotating plug 2 is rotated and erected, the plug part 21 is inserted into the socket slot 312. The socket part 31 is provided with two socket pieces 311 arranged opposite to each other and standing vertically, and when the plug part 21 is inserted into the socket slot 312, the two socket pieces 311 can firmly clamp the plug part 21, so as to realize reliable plug-in between the plug part 21 and the socket part 31. Specifically, the middle areas of the two socket pieces 311 are concave inwards, and the top areas are arranged to be open, so as to facilitate the insertion of the plug part 21 and firmly clamp the plug part 21.

[0041] like Figure 8 and Fig. 9 As shown, the rotating plug 2 also includes a rubber-coated portion 22, and two connecting ears 221 are arranged at one end of the rubber-coated portion 22 close to the housing 1; the plug-in portion 21 has two, one can be used as a live line, and the other can be used as a neutral line. The two connecting ears 221 are respectively wrapped around the two plug-in portions 21. Two mounting holes 111 are provided on the housing 1, and the two connecting ears 221 are rotatably mounted in the two mounting holes 111 to realize the rotation of the rotating plug 2. The two connecting ears 221 can be specifically mounted in the two mounting holes 111 through the rotating shaft 6.

[0042] Specifically, the two connecting ears 221 are provided with a first positioning groove 221a and a second positioning groove 221b, and the mounting hole 111 is provided with a first positioning protrusion 111a1. When the rotating plug 2 is rotated and erected, the first positioning groove 221a is embedded in the first positioning protrusion 111a1; when the rotating plug 2 is rotated and stored on the housing 1, the second positioning groove 221b is embedded in the first positioning protrusion 111a1. This solution realizes the positioning of the rotating plug 2 in the folded storage state and the erected use state through the respective cooperation of the first positioning groove 221a, the second positioning groove 221b and the first positioning protrusion 111a1, thereby improving the state retention capability of the rotating plug 2.

[0043] like Figure 1 , Figure 2 , Figure 8 and Fig. 9As shown, the surface of the housing 1 is provided with a mounting boss 11, and the mounting hole 111 is provided on the mounting boss 11; the end of the rubber-encapsulated portion 22 close to the housing 1 is provided with an avoidance groove 222 corresponding to the mounting boss 11, and two connecting ears 221 are provided in the avoidance groove 222; when the rotating plug 2 is rotated and erected, the avoidance groove 222 covers the mounting boss 11. The mounting boss 11 can provide sufficient installation positions for the installation of the connecting ears 221. The setting of the avoidance groove 222 can play the role of avoiding the mounting boss 11, ensuring the rotation of the rotating plug 2. At the same time, it can cover the mounting boss 11 when the rotating plug 2 is erected for use.

[0044] More specifically, the plug-in portion 21 and the connecting ear portion 221 are L-shaped. The L-shaped plug-in portion 21 and the connecting ear portion 221 facilitate the plug-in connection between the plug-in portion 21 and the socket portion 31. The first positioning groove 221a is provided on the side surface of one end of the connecting ear portion 221 close to the avoidance groove 222, and the second positioning groove 221b is provided on the side surface of one end of the connecting ear portion 221 away from the avoidance groove 222.

[0045] Furthermore, if Fig.12 As shown, the L-shaped plug-in portion 21 is provided with an inclined connection portion 211 at the bend, and the angles at both ends of the inclined connection portion 211 are obtuse. The setting of the inclined connection portion 211 can make the plug-in portion 21 not bend directly, increase the transition amplitude at the bend, and facilitate the rubber coating of the connecting ear portion 221.

[0046] Such as 10 to Fig.13 As shown, the rotating plug 2 also includes a connecting piece 23 and a plug part 24, and one end of the plug part 24 and the connecting piece 23 are installed in the rubber-coated part 22. The connecting piece 23 is installed on the plug part 21, and the plug part 24 is connected to the connecting piece 23. The function of the plug part 24 is to be inserted into the jack of the power socket when the power adapter is used. The electrical connection between the plug part 21 and the plug part 24 is realized by setting the connecting piece 23, which is convenient for their respective production and assembly. The connecting piece 23, the plug and the plug part 21 are all made of conductive metal materials, and the rubber-coated part 22 is made of plastic material.

[0047] Furthermore, the rotating plug 2 further includes an inner bracket 25, and an installation cavity 223 is provided at one end of the rubber-coated portion 22 away from the connecting ear portion 221, and the inner bracket 25 is installed in the installation cavity 223; the plug portion 24 is installed in the inner bracket 25. The provision of the inner bracket 25 facilitates the installation and connection of the plug portion 24. Installing the inner bracket 25 in the installation cavity 223 can also achieve a secure assembly of the inner bracket 25.

[0048] The connecting piece 23 is provided with a groove 231 which is recessed in a direction away from the end of the plug part 24, and the end of the plug part 24 is pressed against the groove 231. The provision of the groove 231 can limit the end of the plug part 24, thereby improving the connection stability between the plug part 24 and the connecting part. The connecting piece 23 is provided with a mounting opening 232, and the end of the plug part 21 close to the connecting piece 23 is provided with two limiting sub-parts 212 which are arranged oppositely and tilted outwards, and the mounting opening 232 is clamped on the two limiting sub-parts 212. Through the cooperation of the limiting sub-parts 212 and the mounting opening 232, the plug part 21 and the connecting piece 23 can be reliably connected together. Among them, after the two limiting sub-parts 212 are inserted into the mounting opening 232, the two limiting sub-parts 212 can be folded outwards. Since the limiting sub-parts 212 are relatively small, they can be folded relatively easily.

[0049] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present utility model rather than to limit it. For those skilled in the art, the technical solutions described in the above embodiments can be modified, or some of the technical features therein can be replaced by equivalents; and all these modifications and replacements should fall within the scope of protection of the claims attached to the present utility model.
