Tail connects, and to form loop coil, so two square coil junctions, has appropriate adjustment.In these square coils
The heart is identical, all at the center of display screen；In these square coils, a coil in outermost is the rectangular lines of area maximum
Circle, size are slightly less than the area of the display screen of the mobile terminal.
In the present embodiment, one end being connect with the cathode of the charging circuit of the second wireless charging built-up coil
It is drawn from the central area of the mobile terminal, the other end of the second wireless charging built-up coil is from the mobile terminal
Fringe region is drawn.
As shown in figure 3, in the present embodiment, one end of the second wireless charging built-up coil is the second wireless charging group
The cathode of zygonema circle, the other end of the second wireless charging built-up coil are the anode of the second wireless charging built-up coil；Make
For another embodiment, the anode and cathode can be exchanged.
In the present embodiment, the other end of the second wireless charging built-up coil and the anode of isolation circuit connect.Institute
It states isolation circuit and includes diode.With forward conduction, the function of reversely ending, so that cradle is only unidirectionally filled to mobile terminal
Electricity avoids reverse charging.
As another embodiment, the concentric anode coil can also be oval coil, circular coil or other shapes
The coil of shape, as long as can realize the effect of large area wireless charging, the shape of coil using the space for shielding circuit as much as possible
Shape both had relationship with the shape of mobile terminal display screen, also had relationship, power transmission coil with the shape of the power transmission coil on cradle
It to be overlapped as much as possible with power receiving coil, could realize maximum charge efficiency.
