[0054] Reference Figures 1 to 8 According to another aspect of the present application, the present application also provides a combination device, which includes the above-mentioned charging plug, and the charging plug is provided with two, and the signal pin 210 on one of the two charging plugs is inserted into the slot 2231 on the other charging plug.

[0055] In the embodiment of the present application, the conductive part 100 includes a conductive mounting part 110 and a conductive pin 120. The conductive pin 120 is mounted on the conductive mounting part 110. The conductive pin 120 is made of metal. The conductive mounting part 110 is provided with a conductive socket 130 for inserting the conductive pin 120 on another charging plug and cooperating with the conductive pin 120 on the conductive mounting part 110 to achieve power transmission. The conductive socket 130 is provided on one side of the conductive pin 120. At the same time, when the signal pin 210 on one charging plug is inserted into the slot 2231 on the other charging plug, the end face of the signal pin 210 fits with the bottom of the slot 2231, and the peripheral surface of the signal pin 210 fits with the slot wall of the slot 2231; in addition, the combined device in the present application is a part of the charging device.

[0056] In summary, the implementation of the charging plug and the combination device provided in this embodiment has at least the following beneficial technical effects: the charging plug in the present application can not only use the conductive part 100 to transmit current, so that it has a power transmission function, but also can realize the transmission of electrical signals by inserting the signal pin 210 on the charging plug into the slot 2231 on another charging plug, so that it has an electrical signal transmission function, avoiding the need to use two types of charging plugs when power transmission and signal transmission are required at the same time, which not only improves the convenience of use, but also greatly enriches the use of the charging plug.
