Abstract
A connector has a first end provided with a first interface and a second end provided with a second interface. The second interface includes a first switch unit and a second switch unit, where the second switch unit is connected to a control terminal of the first switch unit and a ground pin of the second interface, and a preset reference voltage is input into the ground pin of the second interface. In a case that the second interface is disconnected from a to-be-charged device, the first switch unit is in an off state. In a case that the second interface is connected to the to-be-charged device, the ground pin of the second interface is connected to a ground pin of the to-be-charged device, the ground pin of the second interface is grounded, and the first switch unit is in an on state.
Claims12
A connector, wherein a first end of the connector is provided with a first interface, a second end of the connector is provided with a second interface, the first interface is connected to a charging power supply, and the second interface comprises:
- a first switch unit, wherein the first switch unit is connected in series between a power input terminal and a power output terminal of the second interface;
- and
- a second switch unit, wherein the second switch unit is connected to a control terminal of the first switch unit and a ground pin of the second interface, and a preset reference voltage is input into the ground pin of the second interface, wherein
- in a case that the second interface is disconnected from a to-be-charged device, the first switch unit is in an off state;
- and in a case that the second interface is connected to the to-be-charged device, the ground pin of the second interface is connected to a ground pin of the to-be-charged device, the ground pin of the second interface is grounded, and the first switch unit is in an on state.
