Abstract

The invention discloses a high-current and high-power maintenance-free slip ring. The high-current and high-power maintenance-free slip ring comprises a mounting plate, wherein a bearing pedestal is arranged on the top surface of the mounting plate; an inner ring of the bearing pedestal is connected with the slip ring; a stand column I is arranged on the top surface of the slip ring; the top end of the stand column I is connected with a rotating ring; the stand column I is provided with conductive rings; an outer ring of the bearing pedestal is connected with a stand column II; the top end of the stand column II is connected with a protective cover; the stand column II is provided with electric brushes with conductive columns; the conductive columns are elastically connected with the corresponding electric brushes through springs; the conductive columns are connected with the corresponding conductive rings in a fitting manner; a dust holding groove is formed in the connecting place between the stand column II and the outer ring of the bearing pedestal; and the corresponding fitting places between the conductive columns and the conductive rings are vertically corresponding to the dust holding groove. The stand column I is driven by a shifting fork to rotate so as to enable the conductive rings and the corresponding conductive columns on the electric brushes to be in friction constantly to realize electric connection; powder generated in the friction can naturally fall into the dust holding groove without being cleaned, so that the maintenance-free effect is realized; and in addition, the cost is effectively lowered while the reliability is high.

Description

technical field [0001] The invention belongs to the technical field of electrical connector slip rings, in particular to a maintenance-free slip ring with high current and high power. Background technique [0002] In the electrical connection system, the slip ring technology is widely used, and the traditional high-current and high-power slip ring adopts the contact form of the sliding friction electrical contact pair, and the sliding friction between the electrical contact materials will inevitably cause a large amount of grinding powder. During the process, it is easy to backlog in the conductive place and cannot be discharged, which will cause the insulation resistance of the slip ring to increase, resulting in the failure of the electrical connection of the slip ring and poor reliability; moreover, a large amount of powder generated needs to be maintained irregularly according to the usage conditions, resulting in slip rings. Increase in ring usage costs. [0003] The f...
