Description

Technical Field

[0001] This utility model relates to the field of conductive slip ring technology, and in particular to a conductive slip ring brush filament structure. Background Technology

[0002] Conductive slip rings, also known as current collector rings, are mainly used to conduct electricity at the connection between rotating shafts and solid devices, preventing wires from twisting and being damaged during rotation. The principle of a conductive slip ring is that the copper ring of the rotating part rotates with the rotating shaft, and the fixed brush bristles generate current through friction with it. The current is then transmitted to the external circuit through the terminal block.

[0003] Currently, in the existing conductive slip ring brush filament structure, increased pressure can reduce contact resistance during use, but exceeding a threshold will lead to a sharp increase in frictional torque and accelerated wear. Therefore, it is necessary to adjust and monitor the pressure of the conductive slip ring. Thus, in order to improve the service life of the conductive slip ring brush filament and to promote technological progress in the industry and enhance core technological competitiveness, this application proposes a new implementation scheme that differs from the existing conductive slip ring brush filament structure. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a conductive slip ring brush filament structure to solve one or more problems in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A conductive slip ring brush filament structure includes a terminal block and a housing. The terminal block is mounted on the housing. The bottom of the terminal block has two sliding grooves. Multiple guide rods are fixedly connected between the inner walls of the two sides of the sliding grooves. An insulating slide plate is slidably sleeved between the multiple guide rods. Multiple brush filament bodies are fixedly connected to one side of the insulating slide plate. The middle part of the brush filament body has a first bend, and one end of the brush filament body has a second bend. A spoke-type sensor is fixedly connected to one side of the inner wall of the sliding groove. The spoke-type sensor can contact the insulating slide plate. Adjusting screws are threaded to both sides of the terminal block. One end of the adjusting screw contacts one side of the insulating slide plate.

[0007] Furthermore, a sealing cover is fixedly connected to the top of the terminal block, and a display is embedded in the top of the sealing cover. The display is electrically connected to the spoke-type sensor.

[0008] Furthermore, the sealing cover plate is provided with multiple mounting holes.

[0009] Furthermore, a fixed wire is inserted into one end of the terminal block, and the fixed wire is electrically connected to the brush body.

[0010] Furthermore, both sides of the outer casing are provided with adjustment holes, and the adjustment screw is sleeved with the adjustment hole.

[0011] Furthermore, bearings are embedded at both ends of the outer shell, and an insulating shaft is inserted between the two bearings. Multiple conductive rings are fixedly sleeved on the outer wall of the insulating shaft, and the conductive rings are in contact with the brush bristle body.

[0012] Furthermore, a movable wire is threaded through one end of the insulating shaft, and the movable wire is electrically connected to the conductive ring.

[0013] Furthermore, fixed brackets are fixedly connected to both sides of the outer wall of the outer shell.

[0014] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0015] 1. By adjusting the screw and connecting plate with a threaded connection, the insulating slide plate is moved along the guide rod, thereby adjusting the pressure of the brush bristle body on the conductive ring. At the same time, the pressure is monitored by a squeeze wheel spoke sensor to extend the service life of the conductive slip ring brush bristles.

[0016] 2. The first bend allows the bristle body to fit more tightly with the conductive ring. Then, the second bend reduces the friction between the bristle body and the conductive ring, thereby making the conductive ring rotate more smoothly and reducing wear. Attached Figure Description

[0024] Reference Figures 1-5 A conductive slip ring brush filament structure includes a terminal block 1 and a housing 15, wherein the terminal block 1 is mounted on the housing 15 by bolts;

[0025] The bottom of the terminal block 1 is provided with two sliding grooves 4. Multiple guide rods 5 are integrally formed between the inner walls of the two sides of the sliding grooves 4. An insulating slide plate 6 is slidably sleeved between the multiple guide rods 5. Multiple brush bristle bodies 8 are fixed to one side of the insulating slide plate 6 by bolts. The brush bristle bodies 8 are made of Ag-Pd alloy.

[0026] The middle part of the bristle body 8 is provided with a first bending part 9, and one end of the bristle body 8 is provided with a second bending part 10.

[0027] A spoke-type sensor 11 is fixed to one side of the inner wall of the sliding groove 4 by bolts. The spoke-type sensor 11 can contact the insulating slide plate 6. The model of the spoke-type sensor 11 can be selected as LSZ-F03BM. The output signal of the spoke-type sensor 11 is 0-10V analog quantity with a sampling frequency of 1kHz.

[0028] Both sides of the terminal block 1 are threaded with adjusting screws 12. The adjusting screws 12 are threaded through the insulating slide plate 6. The adjusting screws 12 are moved by the threaded connection between the terminal block 1 and the terminal block 1, thereby pushing the insulating slide plate 6 to move along the guide rod 5, which in turn causes the insulating slide plate 6 to squeeze the spoke sensor 11; thereby adjusting the pressure of the brush body 8 on the conductive ring 19.

[0029] A sealing cover 2 is fixed to the top of the terminal block 1 by bolts. A display 13 is embedded in the top of the sealing cover 2. The display 13 is electrically connected to the spoke sensor 11.

[0030] The sealing cover 2 is provided with multiple mounting holes 3, which facilitates the fixing of the sealing cover 2 to the outer casing 15.

[0031] One end of the terminal block 1 is connected to a fixed wire 14, which is electrically connected to the brush body 8.

[0032] The outer casing 15 has adjustment holes 16 on both sides, and the adjustment screw 12 is sleeved with the adjustment hole 16 with a gap, which facilitates the operation of the adjustment screw 12.

[0033] Bearings 17 are embedded at both ends of the outer casing 15, and an insulating shaft 18 is inserted between the two bearings 17. The bearings 17 reduce the rotational friction of the insulating shaft 18 and increase the durability of the equipment. Multiple conductive rings 19 are fixedly sleeved on the outer wall of the insulating shaft 18, and the conductive rings 19 are in contact with the brush body 8.

[0034] A movable wire 20 is threaded through one end of the insulating shaft 18. The movable wire 20 is electrically connected to the conductive ring 19, thereby facilitating the connection between the movable wire 20 and the conductive ring 19.

[0035] Both sides of the outer wall of the outer shell 15 are integrally formed with fixed brackets 21, which are used for fixing and installing the overall structure.

[0036] The working principle of this embodiment is as follows: When in use, the bristle body 8 contacts the conductive ring 19, and then the adjusting screw 12 is turned with a tool. Under the action of the threaded connection between the adjusting screw 12 and the terminal block 1, it moves, thereby pushing the insulating slide plate 6 to move along the guide rod 5, squeezing the spoke sensor 11. Then, the spoke sensor 11 monitors the pressure and displays it on the display 13, thereby controlling the pressure between 8-15 Newtons, and thus adjusting the pressure of the bristle body 8 on the conductive ring 19.

[0037] The first bend 9 makes the bristle body 8 fit more tightly with the conductive ring 19. Then, the second bend 10 reduces the friction between the bristle body 8 and the conductive ring 19, thereby making the conductive ring 19 rotate more smoothly and reducing wear.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
