Optionally, in an embodiment, the first interface is a lighting interface and the second interface is a type-C interface. The lightning interface is a high-speed multifunctional I/O interface, also called a lightning interface; the Type-C interface is an USB interface appearance standard, has a smaller volume than both Type-A and Type-B, and can be applied to interface types of PC (host device) and external device (slave device such as mobile phone). Then, the first interface female seat is a lighting female seat (L female seat for short), the first interface male head is a lighting male head (L male head for short), the second interface female seat is a type-C female seat (C female seat for short), and the second interface male head is a type-C male head (C male head for short).
It can be understood that, for the current application device, the charging interfaces are all lighting interfaces (L female sockets), so that the adaptor 10 and the data line 20 are adopted, and the L male end of the data line 20 is connected with the L female socket of the application device, so that charging can be directly performed. However, the future application device may not use the lighting interface any more, but instead use the type-C interface (C socket), so if the adapter 10 and the data line 20 described above are still used, the future application device cannot be connected to achieve charging, resulting in waste of existing wires.
Therefore, the present embodiment improves the adapter 10 on the original system, configures the L female socket on the adapter 10, and then turns the L male and C male of the existing data line 20, the L male of the data line 20 is connected with the L female socket of the adapter 10, and the C male of the data line 20 is connected with the electronic device, so as to realize the sequential connection of the adapter 10, the data line 20 and the electronic device, thereby charging the electronic device. In this way, only the adapter 10 needs to be modified, and the existing data line (C-L data line) can still be used for the data line 20, so that no waste of the existing data line is caused.
Referring to fig. 2, fig. 2 is a schematic structural diagram of a second embodiment of a charging system provided in the present application, and the charging system 100 includes an adapter 10 and a data line 20.

1) Adapter 10, l-C data line: the L male of the L-C data line is connected with the L female of the adapter 10, and the C male of the L-C data line is connected with the C female of future apple equipment;
2) Adapter 10, C-C data line: one end of the C-C data line is connected with the C female seat of the adapter 10 by the C male head, and the other end of the C-C data line is connected with the C female seat of the android device (or other non-apple devices) by the C male head;
3) Adapter 10, C-L data line: the C male of the C-L data line connects with the C female of the adapter 10 and the L male of the C-L data line connects with the L female of the existing apple equipment.
It will be appreciated that the present embodiment improves the adaptor 10 on the original system, configures the L-shaped socket and the C-shaped socket on the adaptor 10, and then uses the existing L-C data line 20 and the existing C-C data line 20 to charge the existing apple device, future apple device and existing android device. In this way, only the adapter 10 needs to be modified, and the existing data line (C-L data line) can still be used for the data line 20, so that no waste of the existing data line is caused.
