Detailed ways

As shown in the drawings, a charger in this embodiment includes a charger body 1 and a charging plug. The charger body 1 includes a housing and a charging circuit board disposed in the housing. The housing is assembled by housing one 1-3 and housing two 1-4. The charger body 1 is provided with a USB output socket 1-2. The charger body 1 is provided with a charging plug receiving slot 1-1. The charging plug is arranged in the charging plug accommodating groove 1-1 and is hinged with the charger body 1 . The charging plug in this embodiment is a two-pin plug 2 . When the two-pin plug 2 needs to be used, the two-pin plug 2 is rotated, and the pins of the two-pin plug 2 are stretched out from the charging plug receiving groove 1-1 of the charger body 1, which can be used for American standard and Japanese standard sockets. Of course, the structure of the charging plug can also be changed according to the design, such as making the charging plug attached to the charger body 1 adapt to a Chinese standard socket. A set of extension plugs 3 is also included. The extension plug 3 includes a plug body 3-2, a plug block 3-1 arranged below the plug body 3-2, and a pin 3-3 arranged above the plug body 3-2. The pins 3-3 of the set of extension plugs 3 are set according to different standards. Embodiment 1 shown in accompanying drawing 4 is a pin provided according to European standards, embodiment 2 shown in accompanying drawing 7 is a pin provided according to Australian standard, and embodiment 3 shown in accompanying drawing 8 is provided according to British standard prongs. The outer dimensions of the plug block 3 - 1 correspond to the charging plug receiving groove 1 - 1 of the charger body 1 . The plug block 3-1 is provided with a connecting groove 3-1-1 for plugging with the two-pin plug 2 . The connection slot 3-1-1 is provided with a contact piece 3-4 electrically connected to the pin 3-3 of the two-pin plug 2 and the extension plug 3 respectively. The extension plug 3 and the charger body 1 form a relatively fixed connection structure after the plug block 3-1 is inserted into the charging plug receiving groove 1-1 of the charger body 1 . At the same time, the two-pin plug 2 is inserted into the connection slot 3-1 to form a structure in which the two-pin plug 2 is electrically connected to the pin 3-3 of the extension plug 3. In order to better fix the extension plug 3 to the charger body 1, a limiting protrusion 1-1-1 is provided in the middle of the charging plug receiving groove 1-1 on the charger body 1 preferred in this embodiment, and the limiting protrusion 1 -1-1 is provided with a limit groove 1-1-2. Correspondingly, a limiting block 3-5 is provided under the plug body 3-2. When the plug block 3-1 is inserted into the charging plug receiving groove 1-1 of the charger body 1, the limit block 3-5 is plugged into the limit groove 1-1-2, which not only can limit the insertion depth of the plug block 3-1 , it is also possible to better fix the extension plug 3 and the charger body 1 .

When you need to use other standard plugs, you only need to rotate the two-pin plug 2 back into the charging plug accommodating groove 1-1, align the plug 3-1 of the extension plug 3 with the two-pin plug 2 for insertion, and the two-pin plug 2 It is electrically connected with the contact piece 3-4 in the connecting groove 3-1-1. Since the contact piece 3-4 is electrically connected to the pin 3-3 of the extension plug 3, the two-pin plug 2 is electrically connected to the pin 3-3 of the extension plug 3 through the contact piece 3-4, and the input circuit is turned on at this moment. During the transfer process, the two-pin plug 2 on the charger body 1 is used for connection, which saves an additional transfer mechanism, and the transferred charger can be used on a corresponding socket. Since the charger body 1 comes with a two-pin plug 2, it is also convenient for the user to be equipped with one less standard plug.
