Problems solved by technology

[0002] In related technologies, multiple coils may be installed in electronic equipment at the same time, such as NFC (Near Field Communication (NFC) for short) coils and wireless charging coils. It is located outside the other coil, but when the external coil is working, there will be a large current, which will generate a large induced electromotive force on the internal coil, and the circuit where the internal coil is located will have breakdown and overcurrent functional risk

Abstract

The invention discloses a coil assembly and electronic equipment. The coil assembly comprises: a circuit board; a first coil, which is arranged on the circuit board; and a second coil, which is arranged on the circuit board, wherein the second coil and the first coil are spaced in the thickness direction of the circuit board, an area defined by the outer contour of the projection of the first coilon the circuit board is a first area, an area defined by the outer contour of the projection of the second coil on the circuit board is a second area, and the first area and the second area are partially overlapped. According to the coil assembly, when the first coil works, induced electromotive force on the second coil can be reduced, so the functional risks of breakdown and overcurrent of a circuit element where the second coil is located are reduced, and the working reliability of a circuit where the first coil is located and a circuit where the second coil is located is guaranteed.

Description

technical field [0001] The present application relates to the technical field of electronic equipment, in particular to a coil assembly and electronic equipment. Background technique [0002] In related technologies, multiple coils may be installed in electronic equipment at the same time, such as NFC (Near Field Communication (NFC) for short) coils and wireless charging coils. It is located outside the other coil, but when the external coil is working, there will be a large current, and this alternating current will generate a large induced electromotive force on the internal coil, and the circuit where the internal coil is located will have breakdown and overcurrent functional risk. Contents of the invention [0003] The present application proposes a coil assembly, and the coil assembly has high working reliability. [0004] The present application also proposes an electronic device, which includes the above-mentioned coil assembly. [0005] The coil assembly accordi...
