A protective cover includes a first housing configured to receive an electronic device therein, a second housing and a connecting assembly coupling the first housing with the second housing. The connecting assembly includes a first connector assembly including a first connecting shell rotatably coupled to the first housing and a first conducting member capable of coupled to the electronic device, and a second connector assembly including a second connecting shell rotatably coupled to the second housing and two second conducting members electrically coupled to the display screen respectively. When the first conducting member is electrically coupled to one second conducting member, the second housing is capable of rotating relative to the first housing about a first direction. When the second housing is capable of rotating relative to the first housing to a predefined position, the first conducting member is thus electrically coupled to the other second conducting member.
