DETAILED DESCRIPTION

[0022] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0023] Example: Figure 1-Figure 6 The conductive slip ring intelligent adjustment connector shown includes a conductive copper bar 2, a brush positioning strip 5 is fixedly mounted on the conductive copper bar 2, an insulating mounting plate 1 and a sub-mounting plate 12 are fixedly mounted on the conductive copper bar 2, the insulating mounting plate 1 is connected to the stator ring using guide pins on both sides, the sub-mounting plate 12 is connected to the rotor ring through a C-shaped structure, a fish scale spring 3 is mounted on the conductive copper bar 2, a fiber brush 4 is fixedly mounted on the conductive copper bar 2, the fiber brush 4 is connected to the conductive copper bar 2 by elastic fixing, and the brush wire height is slightly higher than the brush positioning strip 5, and the fiber brush 4 has adaptive displacement compensation capability in the axial direction. The installation method of the insulating mounting plate 1 realizes the rotary electrical transmission of the conductive slip ring, and the guide pin ensures that the connector has only axial freedom and can be displaced in the axial direction, thereby reducing the error caused during processing and assembly. At the same time, when the working environment of the conductive slip ring is poor and there is shaking, the plug-in connector can compensate for the displacement of the axial float. It effectively reduces the processing and precision requirements of the rotor ring and improves the adaptability of the product to harsh environments.

[0024] The fish scale spring piece 3 is made of elastic alloy with high strength, high conductivity and high stress relaxation performance. The pre-pressure generated by elastic deformation of the fish scale spring piece improves the electrical contact performance and contact stability between the plug-in connector and the rotor ring piece.

[0025] The height of the brush wire is slightly higher than the brush positioning strip 5, so that the fiber brush 4 has adaptive displacement compensation capability in the axial direction, ensuring the contact between the plug-in connector and the rotor ring. At the same time, the fiber brush wire adopts high conductivity metal wire to further meet the electrical performance required by high-power slip rings.

[0026] The fish scale shrapnel 3 is slidably mounted on the conductive copper bar 2, and a swing rod 6 is rotatably mounted on the conductive copper bar 2. A slide groove is provided at one end of the swing rod 6, and the lower end of the fish scale shrapnel 3 slides in the slide groove of the swing rod 6. A central rotating wheel 9 is rotatably mounted on the center of the conductive copper bar 2, and a pull rod 8 is rotatably mounted on the central rotating wheel 9. A connecting rod 7 is rotatably mounted on the pull rod 8, and the other end of the swing rod 6 is rotatably connected to the connecting rod 7. The rotation of the central rotating wheel 9 drives the pulling rod 8 to move to both sides, and the pulling rod 8 drives the connecting rod 7 to move. The connecting rod 7 drives the swing rod 6 to rotate on the conductive copper bar 2, and the connection part of the swing rod 6 and the connecting rod 7 moves downward, and the connection end of the swing rod 6 and the fish scale shrapnel 3 moves upward, thereby driving the fish scale shrapnel 3 to move upward. At this time, the connector is in a waiting state. When the connector needs to be removed, the central rotating wheel 9 is rotated in the opposite direction, and the fish scale shrapnel 3 moves downward, which is convenient for disconnecting from the rotor ring. By setting this structure, the connector has the function of adjusting the switch.

[0027] A twist switch 10 is fixedly mounted on the central rotating wheel 9. The central rotating wheel 9 can be easily rotated by twisting the switch 10.

[0028] A transverse sliding rod 11 is slidably mounted on the conductive copper bar 2. Two transverse sliding rods 11 are provided. One transverse sliding rod 11 is fixedly connected to the insulating mounting plate 1, and the other transverse sliding rod 11 is fixedly connected to the auxiliary mounting plate 12. The transverse sliding rod 11 is fixedly connected to the insulating mounting plate 1 or the auxiliary mounting plate 12 through the mounting plate bolts 13. The two sides of the rotating shaft on the central rotating wheel 9 are provided with threads arranged in opposite directions. The transverse sliding rods 11 on both sides are threadedly matched with the rotating shaft on the central rotating wheel 9. The rotation of the rotating shaft on the central rotating wheel 9 drives the transverse sliding rods 11 on both sides to move to both sides, and the fish scale shrapnel 3 moves upward at the same time. When the central rotating wheel rotates in the opposite direction, the transverse sliding rods 11 on both sides move toward the center, driving the insulating mounting plates 1 on both sides to move toward the center, reducing the spacing, and breaking away from the connection with the stator ring sheet. The fish scale shrapnel 3 also moves downward to break away from the connection with the rotor ring sheet.

[0029] Insulating mounting plates 1 and auxiliary mounting plates 12 are arranged on both upper and lower sides of the connector, and upper and lower ends of the transverse sliding rod 11 are respectively connected to the insulating mounting plates 1 or auxiliary mounting plates 12 on the upper and lower sides.

[0030] The brush positioning bar 5 is fixedly mounted on the conductive copper bus 2 by means of positioning bar bolts 14 .

[0031] The brush positioning strip 5 is made of self-lubricating copper graphite material. During the sliding process, the good thermal conductivity of copper can take away the heat generated by the friction between the friction brush and the rotor ring. At the same time, graphite has excellent lubricity, and part of the wear debris will be transferred to the surface of the rotor ring to form a stable solid lubricating film containing graphite, which can effectively reduce the friction coefficient and improve the electrical contact performance and service life of the plug-in connector.
