Detailed Description
The utility model is described in further detail below with reference to fig. 1-5.
The embodiment of the utility model discloses a disc type conductive slip ring.
Example 1
Referring to fig. 1, the disc-type conductive slip ring comprises a stator disc 1 and a rotor disc 2, wherein the stator disc 1 and the rotor disc 2 are concentrically arranged, and a plurality of conductive rings 11 are concentrically fixed on the stator disc 1. A plurality of metal spring plates 21 are fixedly connected to the rotor disc 2, the metal spring plates 21 are abutted against the conducting rings 11, and at least one metal spring plate 21 is abutted against each conducting ring 11. The metal elastic piece 21 is fixedly connected with an elastic piece 3, and the elastic piece 3 is used for driving the metal elastic piece 21 to be abutted against the conductive ring 11. When the stator disc 1 and the rotor disc 2 are assembled together, the metal spring pieces 21 abut against the corresponding conductive rings 11. The metal spring piece 21 can be always abutted against the conductive ring 11 by means of the elasticity of the elastic piece 3 in the use process of the conductive slip ring, so that the possibility that the metal spring piece 21 is separated from the conductive ring 11 due to limited elasticity of the metal spring piece 21 is reduced. The elastic piece 3 is used for keeping the metal elastic piece 21 in good contact relation with the conductive ring 11, so that stable electric power and signal transmission is generated between the stator disc 1 and the rotor disc 2.

Referring to fig. 2, three conductive rings 11 are concentrically fixed on the stator plate 1 in this embodiment, and four, five, etc. conductive rings 11 may be provided in other implementations, where the more the number of conductive rings 11, the denser the interval, the stronger the signal transmission capability.
A plurality of supporting ribs 4 are fixedly connected to the stator plate 1, the supporting ribs 4 are annular and are concentric with the conducting rings 11, and the supporting ribs 4 are located between the adjacent conducting rings 11. The number of the supporting ribs 4 in the present embodiment is two, and the number of the supporting ribs 4 and the number of the conductive rings 11 are each other, and since the supporting ribs 4 are provided between the adjacent conductive rings 11, the number of the supporting ribs 4 is one less than the number of the conductive rings 11, for example, when the number of the conductive rings 11 is four, the number of the supporting ribs 4 is three. Adjacent conductive rings 11 are separated by support ribs 4, thereby reducing the likelihood of shorting adjacent conductive rings 11.
In this embodiment, the supporting rib 4 is provided with a plurality of ventilation openings 41, the ventilation openings 41 are obliquely arranged, and the ventilation openings 41 are uniformly distributed around the axis of the supporting rib 4. When the stator plate 1 and the rotor plate 2 rotate for a long time, the friction between the metal elastic sheet 21 and the conductive ring 11 causes the temperature to rise, the air flow between the stator plate 1 and the rotor plate 2 is facilitated by the arrangement of the ventilation openings 41, and the air flow path of the ventilation openings 41 arranged obliquely can cover a larger area, so that the effect of facilitating the heat dissipation of the conductive ring 11 is achieved. And the opening of the vent far away from the axis of the supporting edge 4 is larger than the opening near the axis of the supporting edge 4, so that the air flow speed between the metal elastic sheet 21 and the conducting ring 11 is faster, and a better heat dissipation effect is achieved.

So that the metal spring pieces 21 maintain a good contact relationship with the conductive ring 11, thereby enabling stable power and signal transmission between the stator plate 1 and the rotor plate 2.
