Abstract

A wireless module comprises a coil assembly and an induction substrate. The coil assembly is provided with a coil body and an outgoing line. The outgoing line is electrically connected with the coil body to an outgoing line segement. When observed along the direction of a winding shaft, the coil body and the outgoing line are partially overlapped. The induction substrate is provided with an outgoing line accommodating part and an outgoing line segment accommodating part. The outgoing line accommodating part accommodates part of the outgoing line and the outgoing line segment accommodating partis configured to accommodate part of the outgoing line segment. The outgoing line segment and the outgoing line are arranged along a first direction, the size of the outgoing line segment accommodating part is greater than that of the outgoing line accommodating part in a second direction, and the second direction is not parallel to the first direction and the winding shaft.

Description

technical field [0001] The invention relates to a wireless module, in particular to a wireless module applied to miniaturized electronic devices. Background technique [0002] With the development of technology, many electronic devices (such as tablets or smart phones) now have the function of wireless charging. The user can place the electronic device on a wireless charging transmitter, so that the wireless charging receiver in the electronic device generates current by electromagnetic induction or electromagnetic resonance to charge the battery. Due to the convenience of wireless charging, electronic devices with wireless charging modules are gradually becoming popular with the public. [0003] Generally speaking, a wireless charging module includes a magnetically permeable substrate carrying a coil. Wherein, when the coil is energized to operate in a wireless charging mode or a wireless communication mode, the magnetically permeable substrate can make the magnetic field...
