The invention relates to an oil-immersed contact transmission slip ring, which includes a slip ring stator frame and a slip ring rotor frame with an annular structure. An annular polyimide frame is fixed on the outer wall of the slip ring rotor frame, and several polyimide frame surfaces are installed at intervals. A ring-shaped copper-zinc alloy slideway, the slideway is electrically connected to a single-core copper wire, and the single-core copper wire is electrically connected to a micro-connector; several hollow grooves are evenly distributed in the circumferential direction of the stator frame of the slip ring, and a wiring board is fixedly installed in the hollow groove for wiring. The side of the plate facing the inner side of the slip ring stator frame is electrically connected to the brushes through wires, and the wiring boards in the adjacent hollow slots are connected in series through wires, and the wires are finally electrically connected to the D-Sub connector, which is installed on the D-Sub connector. On the insulating seat of the sub connector, the slip ring stator frame is sleeved on the outside of the slip ring rotor frame. When the slip ring rotor frame rotates, the brush slides along the slideway. The invention can meet the power supply and signal transmission functions of downhole instruments, and adapt to the harsh environment of high speed and strong vibration in downhole.
Description
technical field [0001] The invention belongs to the technical field of petroleum drilling equipment, and in particular relates to an oil-immersed contact transmission slip ring used for an intelligent drilling tool. Background technique [0002] In the oil drilling industry, many intelligent drilling tools need to transmit power and signals in a rotating state. Due to the harsh downhole environment, high speed, strong vibration, etc., it is easy to cause brushes to wear, track, insulation to fail, and single-core wires Easy to loose and other disadvantages. [0003] Therefore, based on these problems, it is of great practical significance to provide an oil-immersed contact transmission slip ring for intelligent drilling tools that can meet the power supply and signal transmission functions of downhole instruments and adapt to the harsh environment of high speed and strong vibration downhole. Contents of the invention [0004] The purpose of the present invention is to ove...
