Abstract

A connecting mechanism is provided for connecting a power adapter and an electronic device. The connecting mechanism includes a first connecting part and a second connecting part. The first connecting part is connected with the power adapter, and includes a first magnetic core, a first winding and a first magnetic element. The second connecting part is connected with the electronic device, and includes a second magnetic core, a second winding and a second magnetic element. The first magnetic element and the second magnetic element are aligned with and magnetically attracted by each other, so that the first connecting part is fixed onto the second connecting part and electromagnetic coupling between the first winding and the second winding is produced.
