Embodiment Construction

[0027] Examples of magnetic cores for non-contact electrical connectors, such as Figure 1-4 As shown, the magnetic core of the non-contact electrical connector includes an inner ring 11, an outer ring 12 and a base 13 arranged at one end of the inner ring and the outer ring.

[0028] In this embodiment, both the inner ring and the outer ring are circular sleeves and each has an integrated structure, wherein the inner ring 11 and the outer ring 12 are coaxially located in the outer ring 12, and the inner hole of the inner ring 11 is axially penetrated. , which are used for the corresponding cables to pass through.

[0029] Both the inner and outer rings are fixed on the base 13, and the base 13 is provided with a through hole corresponding to the inner hole of the inner ring, which is also for the passage of corresponding cables. In addition, the outer edge of the base is provided with Notch 14 , the notch 14 is provided for passing corresponding cables to be wound on the inn...

Abstract

The invention relates to the field of electric connectors, particularly to a magnetic core of a non-contact electric connector and the non-contact electric connector. The magnetic core of the non-contact electric connector comprises an inner ring, an outer ring and a base which is arranged at one ends of the inner ring and the outer ring, wherein the inner ring and the outer ring are respectively fixed on the base through the respective corresponding ends, and one end, which is far away from the base, of the inner ring is protruded outside the corresponding end of the outer ring. Because one end, which is far away from the base, of the inner ring of the magnetic core of the non-contact electric connector is protruded outside the corresponding end of the outer ring, an electromagnetic field can be preferably guided in the wider scope to be distributed, the distance of the power transmission of the non-contact electric connector is longer, the scope of the power transmission of the non-contact electric connector is wider, and the requirement for the shape of the magnetic core can be reduced. In conclusion, the magnetic core of the non-contact electric connector disclosed by the invention not only can conform to the size of the non-contact electric connector, but also can satisfy the requirement for the transmission distance.

Description

technical field [0001] The invention relates to the field of electrical connectors, in particular to a magnetic core of a non-contact electrical connector and the non-contact electrical connector. Background technique [0002] Non-contact power transmission technology is a new technology in the ascendant. Its mechanism of action involves transmitting an alternating electromagnetic field from coil to coil, and induces alternating current in the receiving coil, and supplies it to portable electrical devices such as batteries and mobile phones. The main difficulty of this technology is: how to increase the distance of non-contact power transmission while ensuring the transmission efficiency. [0003] As we all know, adding a magnetic core to the coil can significantly increase the inductance of the coil, so that the same inductance value can be achieved with fewer coil turns, and the reduction in the number of coil turns will reduce the resistance loss of the wire. The magnet...
