Description

Technical Field

[0001] The utility model relates to the technical field of conductive slip rings, in particular to an interference-proof conductive slip ring. Background Art

[0002] Conductive slip ring is a precision power transmission device that transmits electrical signals and electrical energy between rotating parts, rolling or sliding parts of a fixed frame. It is widely used in all electromechanical systems that require unlimited, continuous or intermittent 360-degree rotation, and provide multi-channel rotational power, data and signals. It greatly simplifies the system structure, avoids twisting of the wire during rotation, and can realize the precise transmission of images, data signals and power transmission between two relatively rotating mechanisms.

[0003] Chinese patent announcement number CN219627077U discloses an anti-interference and isolated conductive slip ring, in which different wires are connected to conductive rings of different heights, so that the distance between the wires is relatively far, and the anti-interference components and the arrangement of multiple epoxy resin insulating material partitions are used to prevent the wires from affecting each other. However, the above technology requires overall disassembly and maintenance in actual application, which is difficult to operate, and conductive slip rings of uniform size are difficult to meet the needs of multi-signal synchronous output of different mechanical equipment. Therefore, the utility model provides an anti-interference conductive slip ring to solve the above problems. Utility Model Content

[0022] Specifically, the rotor blocks 3 are added according to the demand, and the guide columns 21 and the limiting plates 22 play the role of limiting the rotor blocks 3 to prevent the rotor blocks 3 from shifting, thereby ensuring the communication effect between the rotor blocks 3.

[0023] Furthermore, a power socket 23 is provided on the bottom surface of the power socket 2, and a first plug-in column 24 is fixedly provided on the top upper side of the power socket 2 corresponding to the plug-in hole 31 of the lowermost rotor block 3, and the power socket 23 is electrically connected to the first plug-in column 24;

Optionally, the connection method between the stator block 63 and the rotor block 3 can be one of contact communication (see: patent announcement number CN201360094Y for details) or contactless communication (see: patent announcement number CN115037368B for details).

[0027] Furthermore, an assembly block 6 is provided between the supporting plates 5, and the assembly block 6 is detachably connected to the adjacent isolation plate 4. The assembly block 6 is provided in an arc-shaped structure, and a cavity is provided in the assembly block 6. A threading barrel 61 is rotatably embedded between the front and rear inner walls of the cavity, and a torsion spring 65 is sleeved on the outer side of the threading barrel 61. The two ends of the torsion spring 65 are respectively fixed to the threading barrel 61 and the inner wall of the cavity.
