TECHNICAL FIELD

[0001] The present application relates to the technical field of conductive slip ring, in particular to a dustproof insulating gasket for conductive slip ring. BACKGROUND

[0002] The conductive slip ring is a key electrical component, which bears the role of transmitting power and signals in the rotating system and is applied in many fields. Since the high-voltage slip ring in the electrical propulsion system is relatively complex, the dustproof work of the ring channel is particularly important. Dust and other pollutants on the ring channel can seriously affect the conductive performance of the ring piece.

[0003] Among them, the common insulating gasket shape is generally a simple circular ring type, the insulating gaskets are 90 degrees with the ring channel in the vertical direction, and there is a large distance between the two insulating gaskets in the horizontal direction. The ring channel is fully exposed. In the rotating process of the conductive slip ring ring body, dust can easily enter the surface of the ring channel. With the accumulation of time, the conductive performance of the ring piece is reduced, thereby affecting the performance of the conductive slip ring. Therefore, we propose a dustproof insulating gasket for conductive slip ring. SUMMARY

[0004] The purpose of the present application is to provide a dustproof insulating gasket for conductive slip ring. The dustproof insulating gasket for conductive slip ring shortens the distance between adjacent insulating outer rings, thereby reducing the exposed space of the slip ring channel, and effectively reducing the dust entering the surface of the slip ring channel.

[0006] The insulating gasket assembly comprises an insulating inner ring, an insulating outer ring and a connecting piece.

[0007] The insulating inner ring is fixedly connected with the slip ring channel, and the insulating inner ring is arranged between adjacent ring pieces. The insulating outer ring is connected with the insulating inner ring through the connecting piece. By shortening the distance between adjacent insulating outer rings, the exposed space of the slip ring channel is reduced, and the dust entering the surface of the slip ring channel is reduced.

[0008] Preferably, the outer end of the insulating outer ring is in inverted trapezoidal shape.

[0009] Preferably, the insulating outer ring is uniformly provided with a groove for storing dust.

[0010] Preferably, the insulating outer ring is fixedly connected with a clamping block, and the clamping block is inserted into a limiting groove in the insulating inner ring.

[0011] Preferably, the ring piece is processed with a V-shaped groove, and the V-shaped groove is used to limit the rotating position of the brush wire.

[0012] Preferably, the connecting piece is a bolt.

[0013] The dustproof insulating gasket for the conductive slip ring is improved in the present application, and has the following improvements and advantages compared with the prior art.

[0014] The insulating inner ring is used to insulate the adjacent ring pieces on the slip ring ring, the detachable connection is adopted between the insulating outer ring and the insulating inner ring, and then the insulating outer ring can be replaced independently, only the space for placing the brush wire is left between the adjacent insulating outer rings in the transverse direction, the brush wire is prevented from jumping, the distance between the adjacent insulating outer rings is shortened, and then the exposed space of the slip ring ring is reduced, and the dust entering the surface of the slip ring ring is effectively reduced.

[0022] Further, the insulating inner ring 31 is used for insulating the adjacent ring piece 2 on the slip ring raceway 1, the detachable connection is adopted between the insulating outer ring 32 and the insulating inner ring 31, thereby facilitating independent replacement of the insulating outer ring 32, only space for placing the brush wire is left between the adjacent insulating outer rings 32 in the transverse direction, and the insulating inner ring 31 and the insulating outer ring 32 are both made of YS20 material, which has the characteristics of high temperature resistance and good insulation performance.

[0023] In some embodiments, as shown in Figure 1 and Figure 4 , the outer end of the insulating outer ring 32 is inverted trapezoidal.

[0024] Further, the design of the inverted trapezoidal outer end of the insulating outer ring 32 makes it difficult for dust to enter the surface of the slip ring raceway 1.

[0025] In some embodiments, as shown in Figure 2 , the insulating outer ring 32 is uniformly distributed with grooves 321, and the grooves 321 are used for storing dust.

[0026] Further, there are several grooves 321 between the ring piece 2 and the insulating outer ring 32 in the vertical direction, which has a certain ability to store pollutants.

[0027] In some embodiments, as shown in Figure 1 and Figure 3 , the insulating outer ring 32 is fixedly connected with a clamping block 322, and the clamping block 322 is inserted into the limiting groove of the insulating inner ring 31.

[0028] Further, the design of the clamping block 322 increases the stability of the connection between the insulating inner ring 31 and the insulating outer ring 32.

[0029] In some embodiments, as shown in Figure 1 , a V-shaped groove 21 is processed in the ring piece 2, and the V-shaped groove 21 is used for limiting the rotation position of the brush wire.

[0030] Further, the design of the V-shaped groove 21 makes it difficult for the brush wire to jump, thereby reducing the possibility of short circuit phenomenon.

[0032] Further, the design of the connecting piece 33 as a bolt facilitates the disassembly of the insulating outer ring 32.

[0033] Working principle:

[0034] First, the insulating inner ring 31 and the ring piece 2 are sequentially installed on the outer wall of the slip ring raceway 1 and fixed, then the insulating outer ring 32 is installed on the outer periphery of the insulating inner ring 31, the clamping block 322 on the insulating outer ring 32 is inserted into the limiting groove of the insulating inner ring 31, the connecting piece 33 is used to penetrate the insulating outer ring 32 and the insulating inner ring 31 for connection, and then the insulating inner ring 31 and the insulating outer ring 32 are fixed. After long-term use, the insulating outer ring 32 is convenient to replace through the design of the connecting piece 33. In the use process of the slip ring raceway 1 and the ring piece 2, the brush wire is inserted into the ring piece 2 through the gap between the adjacent insulating outer rings 32, and the brush wire is embedded into the V-shaped groove 21 of the ring piece 2, so that the brush wire is not easy to jump. At the same time, in the use process, through the design of the inverted trapezoidal shape of the outer end of the insulating outer ring 32 and the groove 321 on the insulating outer ring 32, dust is prevented from entering the surface of the slip ring raceway 1.
