The plug is connected to the receiving body through a connector. The receiving body includes a main body shell, a receiving coil disposed inside the main body shell, and a main body PCB board connected to the receiving coil. A pair of positive and negative electrode contacts are fixedly connected to the main body PCB board. The receiving plug includes a plug housing, a plug PCB board arranged inside the plug housing, a charging plug fixedly connected to the plug PCB board, and a pair of elastic contact pins arranged on the plug PCB board, when the receiving plug is inserted into the charging interface of the mobile phone At the same time, a pair of elastic contact pins are in contact with the positive and negative electrical contacts to form an electrical connection.

More specifically, the connector is a silicone strap, one end of the silicone strap is stuck in the main body shell, and the other end of the silicone strap is stuck in the plug shell.

More specifically, an iron ring is arranged around the receiving coil.

More specifically, the main body casing includes a main body upper cover and a main body lower case.

More specifically, a groove for accommodating the connecting piece is provided in the main body shell.

More specifically, one side of the main body shell is provided with an adhesive layer for attaching the receiving body to the back of the mobile phone.

More specifically, the charging plug is any one of lightning male, Micro-USB male or Type-C male.

Compared with the prior art, the beneficial effects achieved by the utility model are: the patented design can greatly improve the current technical problems of wireless charging: 1. By vertically welding the connector (elastic contact pin) on the plug PCB board of the receiving plug part, The connector (elastic contact pin) can be stably welded on the plug PCB board, which facilitates the realization of automatic welding process, greatly reduces the production cost and improves the yield rate of the product; The spring contact pin realizes the efficient connection with the positive and negative electrode contacts of the receiving body, which can avoid poor connection caused by external impact; 3. It realizes the effect of random plugging and unplugging. When wireless charging is required, the receiving plug remains inserted into the mobile phone; When wired charging is needed, you can unplug the receiving plug, and then plug in the cable to charge, which is very convenient; 4. Through the connection method of the silicone belt, it not only avoids the loss of the plug, but also facilitates the manufacturer to produce separately, according to market demand. Flexible assembly, including but not limited to the current mainstream Apple mobile phone charging head, micro-USB charging head, type c charging head, etc.; 5. Install iron rings/iron sheets/iron rings in the receiving body, which can be matched with the matching car magnetic suction The magnetic suction of the wireless charging bracket can be used as a navigation bracket.
