Referring to fig. 1, fig. 1 shows a schematic diagram of a power adapter in an embodiment of the utility model, where the power adapter includes a cover 1 and an adapter body 2. Referring to fig. 2 to 5, fig. 2 is a schematic perspective view of the cover body 1, fig. 3 is a front view of the cover body 1, fig. 4 is a schematic view of the adapter body 2, and fig. 5 is a schematic view of the adapter body 2 from another view angle. As can be seen from fig. 2 to 5, the adaptor body 2 has pins 21 and first female electrical connectors 23 electrically connected to the pins 21, and the first female electrical connectors 23 electrically connected to the pins 21 can output current required by the electronic product to charge the electronic product by inserting the pins 21 into sockets of a wiring board, for example. The cover 1 includes a first cavity 12, and the first cavity 12 is used for accommodating the pins 21 of the adapter body 2. Through the cooperation of the first cavity 12 of the cover body 1 and the pins 21 of the adapter body 2, the cover body 1 can cover the adapter body 2 and form a covering area.

On this basis, as shown in fig. 2 to 5, in the power adapter in an embodiment of the present invention, specifically, the cover body 1 is provided with the male end 11 of the electrical connector in the covering region thereof, the adapter body 2 is provided with the second cavity 22 capable of accommodating the male end 11 of the electrical connector in the covering region thereof, the female end 23 of the first electrical connector is disposed outside the covering region of the adapter body 2, the male end 11 of the electrical connector can be connected and electrically conducted with the female end 23 of the first electrical connector, as shown in fig. 6, which is an exploded view of the cover body 1, the cover body 1 further includes the adapting circuit module 15 and at least one female end 13 of the second electrical connector, the female end 13 of the second electrical connector is disposed outside the covering region of the cover body 1, and the female end 13 of the second electrical connector is electrically connected with the adapting circuit module 15.

In the power adapter of the utility model, the cover body 1 matched with the adapter body 2 is arranged, so that the cover body 1 can cover the pins 21 of the adapter body 2 in a non-use state. Because the plug pins 21 are wrapped by the cover body 1, the power adapter of the utility model can not generate the situation that the sharp plug pins 21 directly collide with other objects, and because the surface plug pins 21 are accommodated by the cover body 1, the surface plug pins 21 are not exposed to the external environment any more, the plug pins 21 can not be polluted and are not easy to oxidize, and the use effect and the service life of the power adapter of the utility model are ensured.

When the power adapter of the utility model needs to be used, the cover body 1 is separated from the adapter body 2, the pins 21 are exposed again, at this time, the pins 21 can be connected with the wiring board, and the power cord of the electronic product is connected with the first electric connector female end 23 of the adapter body 2, so that the electronic product can be charged through the power adapter of the utility model.

It can be understood that, due to the numerous types of the electronic product connection terminals on the market, in some embodiments, it is likely that the electronic product to be charged does not match the first electrical connector female terminal 23 of the power adapter of the present invention, for example, the electronic product to be charged is equipped with the male terminal of USB a, and the first electrical connector female terminal 23 of the adapter body 2 is the female terminal of Type-C USB, so that the adapter body 2 cannot be directly used for charging the electronic product. As shown in fig. 8, at this time, a user can connect the cover body 1 of the power adapter of the present invention with the first female electrical connector end 23 of the adapter body 2 through the male electrical connector end 11, and connect an electronic product with the second female electrical connector end 13 of the cover body 1. In this way, through the adapter circuit module 15 of the cover 1, the current can be transmitted to the electronic product via the second electrical connector female terminal 13 connected to the adapter circuit module 15 to realize charging.

Thus, when the cover body 1 is covered on the adapter body 2, the pins 21 will not interfere with the components in the cover body 1, thereby ensuring the normal operation of the components in the cover body 1.

On this basis, the adapter circuit module 15 is provided with a jack corresponding to the first accommodating cavity 12, and the adapter circuit module 15 can be plugged with the first accommodating cavity 12 through the jack. The plug-in connection mode strengthens the connection integrity of the adapter circuit module 15 and the cover body 1, and makes the space utilization of the cover body 1 more reasonable.
