Description

Technical Field

[0001] This utility model relates to the field of conductive rings, and in particular to an integrated conductive ring. Background Technology

[0002] Slip rings, also known as collector rings, are used in any electromechanical system that requires continuous rotation while transmitting power and signals from a fixed position to a rotating position. Slip rings improve system performance, simplify system structure, and prevent wires from twisting during rotation. Motors using slip rings, such as synchronous and asynchronous motors, are widely used in industrial sectors, often operating under harsh conditions.

[0003] The existing technology still has the following problems when used: Existing conductive rings typically use a plastic structure to enclose the brush structure, while the internal brush structure is connected to an external metal ring for conductive or signal connection. However, due to the large number of carbon brush structures, any loosening of a single carbon brush structure during sealing will lead to a decrease in yield. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, this utility model provides an integrated conductive ring, which can solve the following technical problems: Existing conductive rings usually use a plastic structure to wrap the brush structure inside, and the internal brush structure is connected to an external metal ring for conductive or signal connection. However, since there are many carbon brush structures, any loosening of a carbon brush structure during sealing will lead to a decrease in yield.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an integrated conductive ring, including an outer metal ring, a support frame formed by injection molding inside the outer metal ring, and a carbon brush assembly. The conductive ring also includes a carbon brush connecting ring. The surface of the carbon brush connecting ring is provided with multiple T-shaped mounting grooves to accommodate the carbon brush assembly. The bottom surface of the carbon brush connecting ring is integrally formed with a receiving arc plate spanning the T-shaped mounting groove. The receiving arc plate supports the carbon brush assembly, and the carbon brush connecting ring and the carbon brush assembly are wrapped and fixed after the support frame solidifies. Holes are left on the inner side of the support frame for the carbon brush rod of the carbon brush assembly to extend out.

[0006] As a preferred embodiment of this utility model, the outer ring of the carbon brush connecting ring is integrally formed with a connecting ring, and the connecting ring is fitted to the inner side of the outer metal ring.

[0007] As a preferred technical solution of this utility model, the bottom of the outer metal ring is formed with a metal ring flange, and multiple connecting holes are provided on the metal ring flange. During the forming of the support frame, a portion of the plastic flows into the connecting holes to form a limiting block.

[0008] As a preferred embodiment of the present invention, the carbon brush assembly includes a carbon brush terminal head and a carbon brush terminal shell, wherein the carbon brush terminal head is formed by inserting a carbon brush rod and pressing it together, and the carbon brush terminal shell is cylindrical.

[0009] Compared with the prior art, the beneficial effects that this utility model can achieve are: 1. The T-shaped mounting groove on the carbon brush connecting ring is used to accommodate the carbon brush assembly, and the receiving arc plate supports the carbon brush assembly placed in the T-shaped mounting groove, which improves the yield rate during injection molding. At the same time, the built-in carbon brush connecting ring places the carbon brush assembly inside the T-shaped mounting groove, which increases the overall strength of the conductive ring and extends its service life.

Example

[0012] Please refer to Figures 1-7As shown, this utility model provides an integrated conductive ring, which includes a carbon brush assembly. The carbon brush assembly includes a carbon brush terminal head 11 and a carbon brush terminal shell 3. The carbon brush terminal shell 3 is rolled into a circle. After inserting the carbon brush rod 4 into the through hole of the carbon brush terminal head 11 and the carbon brush terminal shell 3, the carbon brush terminal head 11 is mechanically pressed to fix the carbon brush rod 4 inside the carbon brush terminal head 11 and the carbon brush terminal shell 3. like Figures 1-6 As shown, the conductive ring also includes a carbon brush connecting ring 10. The carbon brush connecting ring 10 has multiple T-shaped mounting grooves 12. Each T-shaped mounting groove 12 includes a tangential groove and a radial groove. The radial groove of the T-shaped mounting groove 12 points to the center of the carbon brush connecting ring 10 and extends to the inner edge of the carbon brush connecting ring 10. The bottom surface of the carbon brush connecting ring 10 is formed with a receiving arc plate 13, which spans across the radial groove of the T-shaped mounting groove 12. like Figures 1-7 As shown, the carbon brush terminal head 11 of the carbon brush assembly is placed in the tangential groove of the T-shaped mounting groove 12, and the carbon brush terminal head 11 and the tangential groove of the T-shaped mounting groove 12 have the same size. The carbon brush terminal shell 3 of the carbon brush assembly is placed on the receiving arc plate 13, and the receiving arc plate 13 supports the carbon brush terminal shell 3. The carbon brush rod 4 can contact the carbon brush connecting ring 10 for conducting electricity. A part of the carbon brush rod 4 is inside the carbon brush terminal shell 3 and the carbon brush terminal head 11, and a part extends to the outside of the carbon brush terminal shell 3 for contacting the motor rotor for conducting electricity. like Figures 1-5 As shown, the conductive ring also includes an outer metal ring 1. The outer ring of the carbon brush connecting ring 10 is provided with a connecting ring 9. The connecting ring 9 is in close contact with the inner side of the outer metal ring 1, which increases the contact area between the outer metal ring 1 and the carbon brush connecting ring 10.

After the outer metal ring 1, the carbon brush connecting ring 10 and the carbon brush assembly are placed in place, injection molding is performed. After the injection molding solidifies, the support frame 2 wraps the carbon brush connecting ring 10 and the carbon brush assembly inside, but leaves holes for the carbon brush rod 4 to enter and exit. When the support frame 2 is formed, heat dissipation holes 8 are reserved on the outer side of the support frame 2 for heat dissipation of the carbon brush assembly. The bottom of the outer metal ring 1 is provided with a metal ring flange 5. Multiple connecting holes 6 are opened on the metal ring flange 5. Before the support frame 2 is formed, the plastic flows into the connecting holes 6 and solidifies to form a limiting block 7, which increases the connection strength between the outer metal ring 1 and the support frame 2. The carbon brush rod 4 extends into the conductive ring to a certain length, allowing for a certain amount of wear, and the carbon brush rod 4 is made of carbon fiber.
