Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of electrical connection, and in particular to a conductive slip ring with an intermediate loop grounded Background Art
[0002] Conductive slip ring is a kind of rotating power transmission connector. It is a power transmission device that realizes the transmission of electrical signals and electric power between two relatively rotating structures. It realizes sliding power transmission in the rotating state through sliding electric friction contact between the brush wire of the stator part of the slip ring and the ring piece of the rotor part of the slip ring.
[0003] In actual use, one of the slip rings needs to be connected to the shaft and grounded. It is usually placed at the beginning or end to be in direct contact with the shaft or other metal parts. When the surface of the ring is electroplated, the surface of the grounding ring, the shaft or other metal parts, and the plating liquid are all connected at the same time. The plating layer is easy to adhere to the shaft or other metal parts, resulting in flanging and peeling of the plating layer on the edge of the grounding ring, which seriously affects the electroplating quality and conductive performance.
[0004] In addition, due to the surface roughness and flatness errors of the ring, the contact surface of the grounding ring is unstable, resulting in unstable grounding, which becomes a technical problem. The specific cause of this problem is that the grounding ring, metal parts, and electroplating solution are all turned on at the same time during electroplating, causing the coating to adhere to the metal parts, and the contact between the ring and the metal parts is unstable.
[0005] Based on this, the present invention provides a conductive slip ring with a middle loop grounded. Summary of the invention

DETAILED DESCRIPTION
[0023] The technical solution provided by the present invention is further described below in conjunction with the accompanying drawings and according to specific implementation methods.
[0024] like Figure 1 to Figure 6 As shown, a conductive slip ring with a grounded middle loop comprises a base 1, a plurality of power ring sheets 6 are fixedly mounted on the front end of the base 1, an insulating gasket 5 is fixedly mounted between each power ring sheet 6, a grounding ring sheet 2 is fixedly mounted between the stacked power ring sheets 6, and an insulating gasket 5 is fixedly mounted between the grounding ring sheet 2 and the power ring sheet 6. By installing the grounding ring sheet 2 in the middle position of the loop, the problem of unstable grounding connection due to uneven surface when changing sheets is avoided, and at the same time, the problem of poor electroplating effect of the grounding ring sheet 2 due to the plating solution easily adhering to metal parts when electroplating the grounding ring sheet 2 is avoided.
[0025] like Figure 1 to Figure 6 As shown, a grounding shaft 19 is fixedly installed at the front end of the base 1, a grounding threaded hole 7 is provided on the top of the grounding shaft 19, a grounding lug 8 is fixedly installed on the inner ring of the grounding ring sheet 2, a grounding wire welding hole 9 is provided on the grounding lug 8, a grounding wire 3 is fixedly installed in the grounding wire welding hole 9, and the other end of the grounding wire 3 is fixedly installed in the grounding threaded hole 7 through a grounding screw 4, which is used to lead the grounding wire from the inside of the slip ring to achieve reliable grounding.

Wiring clamps 12 are provided at both ends of the wiring board 11. The wiring clamps 12 are used to clamp the contact head or the wire, and transfer the current to the power ring piece 6 through the connecting roller 13. The rolling match between the power ring piece 6 and the connecting roller 13 reduces the wear of the slip ring during operation, and avoids poor contact of the wire or the contact head due to long-term wear when the slip ring rotates.
[0027] like Figure 1 to Figure 6As shown, the inner ring of the superimposed power ring sheet 6 is rotatably installed with two heat dissipation grooves 14, and the heat dissipation grooves 14 are rotatably installed at the front and rear ends of the grounding ring sheet 2 respectively. The heat dissipation grooves 14 are filled with coolant for cooling the power ring sheet 6 when the slip ring is working to prevent the power ring sheet 6 from overheating and causing damage to the insulating pads on both sides of the power ring sheet 6. A plurality of stirring fans 17 are rotatably installed in the heat dissipation grooves 14, and rollers are provided at both ends of the stirring fan 17. The rollers at both ends of the stirring fan 17 roll with the inner ring of the power ring sheet 6. The stirring fan 17 is used to stir the coolant in the heat dissipation grooves 14, so that the coolant in the heat dissipation grooves 14 produces a flow effect, which is convenient for faster heat dissipation of the power ring sheet 6. 14 is provided with a gear pattern 15 on the inner ring, and two transmission rods 16 are rotatably arranged in the base 1. Gears are fixedly mounted at both ends of the transmission rods 16. The gears at the front ends of the two transmission rods 16 are respectively meshed with the gear patterns 15 on the inner rings of the two heat dissipation grooves 14. A driving motor 18 is fixedly mounted on the rear end of the base 1. A gear is fixedly mounted on the front end of the driving motor 18.

When the slip ring is working, the two transmission rods 16 are driven to rotate by starting the driving motor 18, and the corresponding heat dissipation grooves 14 are driven to rotate through the transmission rods 16. When the heat dissipation grooves 14 rotate, the stirring fan 17 is driven to rotate, so as to stir the coolant in the heat dissipation grooves 14 and dissipate the heat.
[0028] like Figure 1 to Figure 6 As shown, the diameter of the ground wire welding hole 9 is 0.1-0.2 mm larger than the diameter of the ground wire 3 .
[0029] like Figure 1 to Figure 6 As shown, the depth of the grounding threaded hole 7 is less than half of the diameter of the grounding shaft 19 .

[0032] like Figure 1 to Figure 6 As shown, the distance between the inner circle of the grounding lug 8 and the grounding axis 19 is less than half of the distance between the inner circle of the grounding ring 2 and the grounding axis 19 .
[0033] Working principle: Before use, the present invention clamps the connected wires through the cooperation of the terminal board 11 and the terminal clamp plate 12, fixes the wires in the terminal bracket 10, and connects the grounding ring plate 2 with the grounding shaft 19 through the grounding wire 3 to improve the stability of the equipment grounding.
[0034] When the slip ring is working, the driving motor 18 is started to drive the transmission rod 16 to rotate, and the corresponding heat sink 14 is driven to rotate, and the coolant in the heat sink 14 is stirred by the stirring fan 17 to improve the heat dissipation effect of the heat sink 14, so as to avoid overheating of the power ring plate 6 during operation and damage to the insulating gasket 5.
