Description

technical field [0001] The invention belongs to the technical field of mechatronics, and relates to a non-contact data transmission device, which can be used for two-way non-contact data transmission of rotating parts, machine joints, speed turntables and underground equipment. Background technique [0002] Various radars, speed turntables, and automated electronic devices used in aviation, aerospace, navigation, and satellites, such as mechanical joints, rotating arms, prospecting and drilling, etc., usually use electrical contact devices such as conductive slip rings to transmit electrical energy or signals. [0003] Modern electronic equipment has higher requirements on the service life and long-term working reliability of such electrical contact devices. The traditional electrical contact device uses the method of dynamic contact between the conductive ring and the brush to realize the transmission of electric energy or signal, and has very strict requirements on the con...
