The invention discloses a charger and a terminal. The charger comprises a first voltage converter for outputting a first voltage value, a second voltage converter for outputting a second voltage value, a switching module and a first charging interface connected with the switching module, wherein when the first detection end of the first charging interface is connected with the second detection endof a second charging interface of the terminal, and when the first charging interface or the second charging interface is in short circuit, the voltage of the first detection end is in a low level; when the first charging interface and the second charging interface are not short circuit, the voltage of the first detection end is in a high level; the switching module is connected with the first voltage converter when the voltage of the first detection end is in a high level; the switching module is connected with the second voltage converter when the voltage of the first detection end is in alow level; and the first voltage value is larger than the second voltage value. According to the charger, the damage to the terminal on the charging interface during short circuit of the charging interface is avoided.
Description
technical field [0001] Embodiments of the present invention relate to the field of electronic products, and in particular, to a charger and a terminal. Background technique [0002] The magnetic suction charging scheme is that the first charging interface on the charger side and the second charging interface on the terminal side are positioned by magnets to realize the physical contact between the first charging interface and the corresponding terminals on the second charging interface, thereby realizing the connection between the charger and the terminal. electrical connection between. Since the magnetic terminals on the first charging interface and the second charging interface are exposed, it is easy to adhere to dirt, liquid, etc., resulting in a short circuit between adjacent terminals; and the magnetic force of the magnet is limited, and the longer the use time, the magnetic attraction decreases. When the first charging interface and the second charging interface are ...
