Abstract
An electron-device protection casing using magnetic connection includes a protection casing for receiving a tablet form electronic device; a device end connecting unit installed in the protection casing for being connected to the electronic device. The device end connecting unit further includes at least one device end magnetic unit which is positioned in the body; the device end magnetic unit serves to be magnetically connected to an external device so that the external connecting unit can be fixedly connected to the external device. The present invention further includes an intermediate connecting unit which further has at least one intermediate magnetic unit positioned for being magnetically connected to the device end magnetic unit; the positions of the device end magnetic units are corresponding to those of the intermediate magnetic units so that the device end magnetic units are attracted by the intermediate magnetic unit.
