Hollow thin electric conduction link

Abstract

The invention relates to the technical field of electrical apparatuses and particularly provides a hollow thin electric conduction link. The traditional electric conduction link mostly has a solid shaft, collector rings and electric brushes are arranged in an axial overlapped mode, no channel for adding of wires exists in the axis direction, line connection between certain execution devices in need of serial connection and with relative rotary motion relies on external open wires, playing of the continuous rotary function of devices is limited, and the devices can only rotate within 360 DEG. In order to solve the problem of wire number application expansion of the electric conduction link, the invention provides a hollow and thin electric conduction link, and a certain number of wires can pass through the hollow channel. With a middle piece associated with a fixing ring and a moving ring, radial and axial constraints on the moving ring by the fixing ring are formed, an electric conduction link structure with the fixing ring and the moving ring capable of rotating relatively combined into a whole is formed, a hollow hole in the moving ring becomes the channel for expanding the wires, and the purpose of wire number series expansion can be realized.

Description

technical field [0001] The invention relates to the technical field of electrical appliances, in particular to provide a hollow thin conductive slip ring. Background technique [0002] Most of the known conductive slip rings are structured with a solid shaft, laminated collector rings and brushes, and there is no channel for increasing the number of wires in the axial direction, thus limiting the function of some application equipment. For example, some robot end effectors mounted in series that rotate continuously use conventional conductive slip rings, and then the line connection of the series-connected executive devices can only be connected through external open wires, which limits the continuous rotation of the executive device function so that it can only rotate within 360 degrees. Contents of the invention [0003] In order to solve the problem of expanding the number of wires of the conductive slip ring, the invention provides a hollow, thin conductive slip ring,...
