Description

Technical Field

[0001] The utility model relates to the technical field of slip rings, and particularly relates to a slip ring. Background Art

[0002] As a key driving device, the performance and reliability of a motor are crucial for the normal operation of the entire system. However, during the operation of the motor, shaft static electricity problems will occur. The higher the rotational speed, the faster the shaft static electricity is generated. If this problem is not properly solved, serious consequences such as electromagnetic interference, reduced service life of the motor, and even motor damage may occur.

[0003] Shaft static electricity refers to the static electric charges accumulated on the motor shaft due to friction or other reasons. The shaft current flows through the motor bearings or other conductive components, which may cause local overheating, accelerate bearing wear, and pose a threat to the normal operation of the motor.

[0009] The crimping portion is bent to press one end of the conductive cluster on the body, and the other end of the conductive cluster protrudes from the body towards the shaft hole to abut against the motor rotating shaft.

[0010] For a slip ring as described above, a groove is provided on the body, and one end of the conductive cluster is embedded in the groove, and after the crimping portion is bent, the conductive cluster is restricted on the groove.

[0019] The beneficial effects of this application are:

[0020] The present invention provides a conductive ring. By using the crimping portion to press the conductive cluster tightly on the body, since the crimping portion is integrally connected to the body, there is no need to additionally provide other structures to crimp the conductive cluster.

[0026] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the following further describes the present invention in detail with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0027] A conductive ring, comprising

[0028] Conductive cluster 1;

[0029] Fixing plate 2, which includes a body 21 and a crimping portion 22 integrally connected to the body 21; a shaft hole 23 for inserting the motor shaft 3 is provided on the body 21;

[0030] The crimping portion 22 is bent to press one end of the conductive cluster 1 against the body 21, and the other end of the conductive cluster 1 protrudes from the body 21 toward the shaft hole 23 to abut against the motor shaft.

[0031] The present utility model provides a slip ring. By using the crimping portion to press the conductive cluster against the body, since the crimping portion is integrally connected to the body, there is no need to additionally provide other structures to crimp the conductive cluster. When the conductive cluster contacts the motor shaft in the shaft hole, the conductive cluster provides a low-impedance path to conduct the current of the motor shaft to the outside, thereby protecting the motor.

[0032] Further, as a preferred embodiment rather than a limitation of this solution, a groove 24 is provided on the body 21. One end of the conductive cluster 1 is embedded in the groove 24, and after the crimping portion 22 is bent, the conductive cluster 1 is restricted on the groove 24. The groove helps to position the conductive cluster and prevent the conductive cluster from moving during the crimping process.

[0033] Further, as a preferred embodiment rather than a limitation of this solution, the groove 24 is formed by stamping on the body 21, and the groove 24 extends to the shaft hole 23. The conductive cluster extends through the groove to the position of the shaft hole and abuts against the motor shaft.

[0034] Further, as a preferred embodiment rather than a limitation of this solution, the crimping portion 22 is cut out from the body 21. The crimping portion 22 includes a connecting edge 25 connected to the body 21 and a separating edge 26 separated from the body 21.

[0035] Further, as a preferred embodiment rather than a limitation of this solution, the connecting edge 25 is located on the side of the conductive cluster 1 to cover from one side of the conductive cluster 1 to the other side and press it. As Figure 1-2 shown.

[0036] Further, as a preferred embodiment rather than a limitation of this solution, a plurality of the crimping portions 22 are arranged on both sides of the conductive cluster 1 in a left-right staggered and alternating manner. As Figure 3 shown, it can effectively prevent the conductive cluster from slipping out from both the left and right sides.

[0037] Further, as a preferred implementation manner of this solution rather than a limitation, the crimping portion 22 is located outside the body 21. The crimping portion 22 includes a connecting edge 25 connected to the body 21. The crimping portion 22 is bent to cover from the end of the conductive cluster 1 to the top thereof. As Figure 4 shown.

[0038] Further, as a preferred implementation manner of this solution rather than a limitation, a fixing hole 27 is provided on the body 21. The fixing hole is used to connect with the conductive base 4.

[0039] Further, as a preferred implementation manner of this solution rather than a limitation, a flanging 28 is convexly provided on the outer edge of the body 21. The flanging is used to cooperate with the conductive base for positioning, and at the same time can strengthen the strength of the fixing plate. The flanging may also not be provided.

[0040] Further, as a preferred implementation manner of this solution rather than a limitation, the conductive cluster 1 includes a plurality of carbon fiber wires 11; or the conductive cluster 1 includes a plurality of carbon fiber wires 11 and a sheath 12 for binding the plurality of carbon fiber wires 11 to form a bundle. In addition to using carbon fiber wires, other metal conductive wires can also be used. The sheath can be in a horn shape in addition to a cylindrical shape. The horn-shaped sheath is convenient for the carbon fiber wires to be inserted into the crimping part and is not easy to run off the wire. The number and position of the carbon fiber wires can be flexibly and reasonably arranged according to actual needs. The sheath can protect the carbon fiber wires from being crushed.

[0041] The above are only the preferred embodiments of this application and are not used to limit the scope of implementation of this application. Other embodiments whose principles and basic structures are the same as or similar to those of this application are all within the protection scope of this application.
