CONTACT DEVICE FOR ELECTRICITY TRANSMISSION BETWEEN MOVABLE PARTS OF SYSTEM Russian patent published in 2022 - IPC H01R39/64 H02K23/18 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering, in particular to devices, which provide continuous energy transmission between separate blocks of one object. A contact pair is created of several brushes being on one part of an object, part of which is pressed against a current-conductive tape forming a contact field of the second part of the object, moving relatively to the first part along a given trajectory, and the other part is pressed back. In a fixed time interval, the other group of contacts of the first part of the object is pressed against the current-conductive tape of the second part of the object, and the first group is pressed back of it and returned to an initial position on the movement trajectory of the contact pair, which provides a constant electrical contact between parts of the object, moving relatively to each other without friction of contacts between each other.

EFFECT: significant reduction in requirements for quality of the manufacture of contact pads of contacts of contact pairs and physical and chemical properties of materials, of which they are made, significant elongation of operation periods of contact pair without deterioration of their characteristics, reduction in power loss between frictional parts of an object, and reduction in a temperature of a contact during operation.
