[0021] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0022] In the specific implementation process, Figures 1 to 5 As shown, the split disc-type conductive slip ring includes a covering frame and a plurality of conductive rings 3 embedded in the covering frame. The conductive ring 3 is composed of two conductive semi-rings. The covering frame is composed of a semi-circular left covering frame 1 and a semi-circular right covering frame 2. The left covering frame 1 and the right covering frame 2 are joined end to end to form an annular contour of electrical contact. An insulating sleeve 5 and a fixing component are provided on the conductive ring 3. The middle part of the insulating sleeve 5 is recessed inward to form an annular groove 6. The fixing component is used to limit the two sides of the annular groove 6.

[0023] The fixing assembly includes a trapezoidal bracket 7 and two symmetrically arranged limit brackets 8. A connecting through hole and a sliding groove 9 are provided on the conductive ring 3 at the position of the insulating sleeve 5. The insulating sleeve 5 is placed in the connecting through hole. The two limit brackets 8 are slidably connected in the sliding groove 9. An elastic member is arranged between the two limit brackets 8 and the sliding groove 9. The elastic member is a compression spring 10. The two ends of the compression spring 10 are respectively fixedly connected to the sliding groove 9 of the conductive ring 3 and the outer side wall of the limit bracket 8. The two limit brackets 8 are respectively fitted with the annular groove 6 of the insulating sleeve 5. The trapezoidal bracket 7 is slidably connected to the side wall of the conductive ring 3. The two limit brackets 8 are bent toward the trapezoidal bracket 7 and are inclined along the side wall of the trapezoidal bracket 7.

[0024] The combination of the left and right covering frames 2 realizes a split design, which is convenient for installation and maintenance, and reduces the cost and complexity of overall replacement. The conductive ring 3 is composed of two conductive half rings assembled into a whole, which can meet the requirements of different sizes and specifications, and improves the flexibility and versatility of use.

[0025] Through the design of the insulating sleeve 5 and the fixing assembly, the limit bracket 8 is fitted with the annular groove 6 of the insulating sleeve 5, ensuring the stable positioning of the conductive ring 3 in the sheath frame, reducing the shaking and deviation during the rotation process, and improving the stability and reliability of the electrical contact. The elastic member further ensures the fastening between the limit bracket 8 and the sliding groove 9, and can maintain a good contact state even in a vibration environment.

[0026] The sliding connection design between the trapezoidal bracket 7 and the limiting bracket 8, and the inclined setting of the limiting bracket 8 along the side wall of the trapezoidal bracket 7, provide flexibility for installation and adjustment, and are convenient for fine-tuning the position of the conductive ring 3 according to actual working conditions to ensure optimal electrical contact pressure and stability. It is also convenient for quick assembly and disassembly. Specifically, by squeezing the trapezoidal bracket 7, the limiting brackets 8 on both sides are driven to slide horizontally in the sliding groove 9, and the elastic member is squeezed so that the two limiting brackets 8 are unfolded to the outside of the insulating sleeve 5. When the insulating sleeve 5 needs to be installed or replaced, it is convenient. When the insulating sleeve 5 needs to be fixed, it is placed in the connecting through hole, and the force applied to the trapezoidal bracket 7 is removed, so that the two limiting brackets 8 are squeezed by the elastic member, thereby fixing the annular groove 6 of the insulating sleeve 5.

[0027] An insulating structure is provided on the sheath frame, and the conductive rings 3 are stacked up and down in the axial direction and isolated from each other by the insulating structure of the sheath frame, thereby reducing signal interference and uncertainty of potential difference, and are suitable for occasions requiring high-precision signal transmission or large current carrying.

[0028] Each conductive half ring has a terminal 4, which extends out of the covering frame in the axial direction. The terminal is placed in the insulating sleeve. The conductive rings 3 are recorded as the first conductive ring 3, the second conductive ring 3, the third conductive ring 3, and the fourth conductive ring 3 from top to bottom. The first conductive ring 3 and the fourth conductive ring 3 are at the two ends of the axial direction, and the second conductive ring 3 and the third conductive ring 3 are in the middle of the axial direction.

[0029] A connecting assembly is provided on one side of the covering frame, and the connecting assembly includes a box body 11. A plurality of ejector pins 12 are provided inside the box body 11 and are ejected out of the box body 11 by a spring. The plurality of ejector pins 12 are in contact with the conductive ring 3. The spring inside the box body 11 is used to ensure that the ejector pins 12 can maintain continuous and stable contact with the conductive ring 3. Even if vibration or slight displacement is encountered during rotation, the elasticity of the spring can automatically adjust to maintain good electrical contact, thereby reducing the risk of poor contact.
