Non-contact power transmission system

The invention relates to the field of electrical connectors, in particular to a non-contact power transmission system. The non-contact power transmission system comprises a transmitting end and a receiving end, wherein each of the transmitting end and the receiving end comprises a magnetic core and a coil; each magnetic core comprises an inner ring, an outer ring and a base; the inner ring and the outer ring are fixed on the base through corresponding ends respectively; the coil is wound on the inner ring; one end, away from the base, of the inner ring protrudes out of the corresponding end of the outer ring. According to the non-contact power transmission system, one end, away from the base, of each of the inner rings of the magnetic cores of each of the transmitting end and the receiving end protrudes out of the corresponding ends of the outer rings. Therefore, the electromagnetic field can be better guided to be distributed in a wider range, so that the non-contact power transmission system has a longer power transmission distance and a wider range, thereby reducing the requirements on the shape of the magnetic core. In conclusion, the non-contact power transmission system is not only consistent with the size of non-contact power transmission systems, but also to meets the requirements on transmission distance.
