Problems solved by technology

If the traditional photoelectric rotary connector manufacturing process is still used, the size needs to be increased by ten times in order to achieve the withstand voltage index of thousands of volts, and the diameter of the photoelectric connector will exceed half a meter, which is obviously not suitable for machines with strict requirements on size and weight. platform environment

Embodiment Construction

[0020] The following description serves to disclose the present invention to enable those skilled in the art to carry out the present invention. The preferred embodiments described below are only examples, and those skilled in the art can devise other obvious variations.

[0021] Such as figure 1 The shown connector includes a central shaft 1, a bracket housing 2 and a housing 3, the two ends of the central shaft 1 are respectively fixedly connected to the inner rings of the upper and lower bearing seats 7, and the two ends of the bracket housing 2 are connected to The outer rings of the upper and lower bearing seats 7 are fixedly connected, and a bearing 8 is arranged between the inner ring and the outer ring of each upper and lower bearing seat 7, so that the support housing 2 and the central shaft 1 can rotate relative to each other. The housing 3 is sleeved on the outside of the bracket housing 2 and rotates together with the bracket housing 2 . The central shaft 1, the ...

Abstract

The invention discloses an electric rotary connector. The electric rotary connector comprises a center shaft and a support housing, wherein the center shaft is coaxially arranged inside the support housing, the support housing can rotate relative to the center shaft, the center shaft is axially provided with multiple electric slip rings, electric connecting blocks are arranged positions, which are opposite to the electric slip rings, on the support housing, and each electric connecting block is electrically connected with the corresponding electric slip ring through a brush filament. The electric rotary connector is characterized in that the two sides of each brush filament are each provided with an insulation structure, and each insulation structure is internally provided with insulation liquid. The connector employs the insulation structures with the insulation liquid, effectively prevents air circulation between brush structures and improves the insulation effect.

Description

technical field [0001] The invention relates to an electrical rotary connector, in particular to an electrical rotary connector suitable for weather resistance and insulation. Background technique [0002] When the first device and the second device of the rotary connector are relatively rotated more than 360°, if it is necessary to exchange electrical information between the two devices, it is often necessary to use an electrical rotary connector for switching. Conventional electric rotary connectors include a central shaft and a bracket housing. The left and right axial ends of the central shaft are rotatably assembled inside the bracket housing through bearings. The central shaft is provided with a plurality of conductive slip rings arranged along the axial front and rear directions. The electric brush wires arranged on the bracket shell are frictionally contacted with each conductive ring respectively. The wires drawn out from the conductive ring are connected to the fi...
