Description

Technical Field

[0001] This utility model relates to the field of conductive slip ring technology, and in particular to a conductive slip ring with strong anti-interference ability. Background Technology

[0002] Conductive slip rings, also known as collector rings, slip rings, current collectors, or busbars, are used in any electromechanical system that requires continuous rotation while transmitting power and signals from a fixed position to a rotating position. Conductive slip rings improve system performance, simplify system structure, and prevent wires from twisting during rotation.

[0003] The inner ring of a conductive slip ring typically passes through a shaft or other rotating component. Currently, conductive slip rings rely solely on the friction of their inner ring to connect with the shaft. During equipment operation, if subjected to external forces such as vibration or impact, the friction between the inner ring and the shaft may be insufficient to resist these forces, causing axial or radial displacement of the inner ring relative to the shaft. This affects the fitting accuracy between the conductive slip ring and other components. Furthermore, the fixed diameter of the inner ring limits its compatibility to components of the same diameter, reducing the equipment's versatility and restricting its application in different projects or experiments. Utility Model Content

[0004] The present invention aims to provide a conductive slip ring with strong anti-interference capability to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A conductive slip ring with strong anti-interference capability includes an inner ring sleeve made of insulating material. The inner ring sleeve has an installation groove, and a conductive ring is connected to the inner wall of the installation groove. The inner ring sleeve is rotatably connected to a shell, and a conductive plate is connected to the shell. A brush is connected to the conductive plate and contacts the conductive ring. The inner ring sleeve has several sets of through slots arranged in a circular array. A clamping block is slidably connected to the inner wall of each through slot. The clamping block has a sliding groove, and a locking block is connected to the inner wall of each through slot. The locking block is slidably connected to the sliding groove. The clamping block has a trapezoidal longitudinal section. A threaded sleeve is threadedly connected to the inner ring sleeve, and the threaded sleeve mates with the clamping block.

[0007] Preferably, the outer shell is composed of a shielding coating, an insulating layer, and a metal layer from the inside out.

[0008] Preferably, the clamping block has an arc-shaped groove.

[0009] Preferably, the clamping block is connected to an anti-slip pad.

[0010] Preferably, the outer shell is connected to a fixing plate, and the fixing plate has fixing holes.

[0011] The beneficial effects of this technical solution compared to existing technologies are as follows:

[0012] (1) This technical solution, by setting up locking blocks, through grooves, sliding grooves, locking blocks, and threaded sleeves, can drive multiple sets of locking blocks to perform circumferential contraction motion, thereby quickly and accurately positioning shaft-type connecting components at the center position of the inner ring sleeve of the conductive slip ring, ensuring the concentricity of the shaft and the conductive slip ring. The circumferential contraction locking blocks can apply uniform pressure to the shaft-type components from multiple directions, providing a more reliable clamping effect than simple friction. During equipment operation, whether subjected to external forces such as vibration, impact, or centrifugal force generated by high-speed rotation, the shaft-type components can be firmly clamped in place, effectively preventing axial or radial displacement and ensuring the stability of the connection between the conductive slip ring and the shaft. Furthermore, through the circumferential contraction motion of the locking blocks, the clamping range of the shaft-type components can be flexibly adjusted, allowing the same conductive slip ring to adapt to various shaft-type connecting components of different diameters. It is no longer limited to the limitation that a fixed inner ring diameter can only adapt to a single shaft diameter, improving the versatility and applicability of the conductive slip ring and reducing the cost of replacing the entire conductive slip ring due to changes in shaft diameter.

[0013] (2) By setting up an outer shell consisting of a shielding coating, an insulating layer, and a metal layer from the inside out, the shielding coating can effectively block external electromagnetic fields from interfering with the signal transmission inside the conductive slip ring, ensuring the stability and accuracy of signal transmission, reducing signal distortion and noise, and ensuring normal operation of the equipment, especially in complex electromagnetic environments. The insulating layer isolates the conductive parts from the external environment, preventing current leakage to the outer shell or other adjacent components, preventing electric shock to personnel and short circuit failures in the equipment, and improving the safety and reliability of the equipment. The metal layer provides a robust outer shell for the conductive slip ring, protecting the internal conductive components, brushes, etc., from external mechanical impacts, collisions, and wear, improving the mechanical strength and durability of the conductive slip ring, and extending its service life. Furthermore, it can work in conjunction with the shielding coating to further enhance the electromagnetic shielding effect, forming a more complete electromagnetic shielding system, better blocking external electromagnetic interference and preventing internal electromagnetic leakage.

[0014] (3) By setting the arc groove, the clamping force can be evenly distributed on the shaft component, avoiding concentration on local points or lines, thereby reducing the pressure on the surface of the shaft component and reducing the risk of the workpiece being clamped, deformed or damaged.

[0015] (4) By setting anti-slip pads, the friction between the clamping block and the shaft component can be increased, and a buffering effect can be played between the clamping block and the shaft component to prevent the clamping block from directly contacting the surface of the shaft component and causing scratches, indentations and other damage.

[0016] (5) By setting a fixing plate and fixing holes, a clear positioning benchmark is provided for fixing the outer shell, avoiding the outer shell from rotating with the inner ring sleeve, which would cause the circuit to be subjected to pulling, twisting and other forces.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0021] like Figure 1-2 The conductive slip ring shown includes an inner ring sleeve 1 made of insulating material. Several sets of annular mounting grooves 2 are formed on the outer wall of the inner ring sleeve 1, and conductive rings 3 are connected to the inner walls of the mounting grooves 2. A housing 4 is rotatably connected to the outer wall of the inner ring sleeve 1. The housing 4 is composed of a shielding coating 16, an insulating layer 15, and a metal layer 14 from the inside out. A fixing plate 5 is connected to the outer wall of the housing 4, and the fixing plate 5 has fixing holes 6. The conductive ring 3 is located inside the housing 4, and a conductive plate 7 is connected to the inner wall of the housing 4. A brush 8 is connected to the conductive plate 7, and the brush 8 abuts against the outer wall of the conductive ring 3. Both the conductive plate 7 and the conductive ring 3 are connected to wires, and two sets of wires extend outwards through the housing 4 and the inner ring sleeve 1, respectively. When the inner ring sleeve 1 and the shaft-like components passing through it rotate, the wires connected to the housing 4 do not rotate accordingly.

[0022] like Figure 1-2As shown, the outer wall of the inner ring sleeve 1 located on the outer side of the outer shell 4 has several sets of through grooves 9 arranged in a ring array. A clamping block 10 is slidably connected to the inner wall of each through groove 9. An arc-shaped groove 12 is formed on the inner end face of the clamping block 10, and an anti-slip pad 13 is connected thereto. Sliding grooves 17 are formed on both sides of the clamping block 10. A locking block 18 is connected to the inner wall of the through groove 9 at a position corresponding to the sliding groove 17. The locking block 18 is slidably connected to the sliding groove 17, preventing the clamping block 10 from disengaging from the through groove 9. The clamping block 10 has a trapezoidal longitudinal section, with its inclined surface facing outwards. An external thread is provided on the outer wall of the right end of the inner ring sleeve 1, and a threaded sleeve 11 is threadedly connected thereto. The threaded sleeve 11 mates with the clamping block 10. When the threaded sleeve 11 is rotated, the threaded sleeve 11 moves to the left along the external thread path. The left end of the threaded sleeve 11 abuts against the inclined surface of the clamping block 10 and presses the clamping block 10 downward along the inclined surface, so that several sets of clamps move simultaneously towards the center of the inner ring sleeve 1 until the anti-slip pad 13 connected to the clamping block 10 abuts tightly against the shaft component located inside the inner ring sleeve 1.

[0023] The specific implementation process is as follows:

[0024] In use, insert the shaft component into the inner ring sleeve 1, positioning it between several sets of clamping blocks 10. Then, rotate the threaded sleeve 11, causing it to move to the left along the external thread, pressing the clamping blocks 10. This ensures that the anti-slip pads 13 on the clamping blocks 10 make tight contact with the shaft component and firmly clamp it. Secure the housing 4 to the appropriate position on the equipment using suitable bolts, nuts, or other fastening devices through the fixing holes 6 on the fixing plate 5. Connect the wire connected to the conductive plate 7 to the power source or signal source that needs to transmit power or signals, and connect the wire connected to the conductive ring 3 to the corresponding receiving device or system.
