Description

Technical Field

[0001] This utility model relates to the field of motor conductive ring technology, and in particular to a plastic-encapsulated motor conductive ring. Background Technology

[0002] During motor operation, the motor conductive ring is a key component, and its performance stability has a significant impact on the overall operating effect of the motor. In traditional technology, due to the size of the motor conductive ring, insulating material is filled between the terminals to prevent conduction between them, and then the terminals are connected together through a molding process. However, in this method of filling the terminals with insulating material and connecting them through molding, the insulating material is prone to displacement during the molding process due to the vibration generated by the injection molding machine when the mold is closed and the internal injection pressure after the mold is closed. This can lead to conduction between the terminals, causing the motor conductive ring to fail, resulting in a technical problem of poor manufacturing yield of the motor conductive ring. Utility Model Content

[0037] like Figure 1 and Figure 7 and Figure 8 As shown, it is the encapsulated motor conductive ring 100 of this utility model.

[0038] like Figures 1 to 4As shown, the encapsulated motor conductive ring 100 includes: a first terminal 10, a second terminal 20, a third terminal 30, a first encapsulated barrier 40, a second encapsulated barrier 50, and an encapsulated disc 60. The first terminal 10 is disposed between the second terminal 20 and the third terminal 30, and is spaced apart from the second terminal 20 and the third terminal 30. Both the first encapsulated barrier 40 and the second encapsulated barrier 50 are encapsulated and connected to the first terminal 10. The first encapsulated barrier 40 is disposed between the first terminal 10 and the second terminal 20, with one end of the first encapsulated barrier 40 facing away from the first terminal 10 abutting against the second terminal 20. The second encapsulated barrier 50 is disposed between the first terminal 10 and the third terminal 30, with one end of the second encapsulated barrier 50 facing away from the first terminal 10.

Through the cooperation of the first encapsulation barrier 40 and the second encapsulation barrier 50, the spacing between each terminal can be stably maintained during the encapsulation process, thereby effectively resisting injection pressure and mold closing vibration, avoiding relative displacement or mutual contact of each terminal due to external force, thereby preventing the terminals from conducting, and achieving the purpose of improving the manufacturing yield of the motor conductive ring.

[0039] The following text, combined with Figures 1 to 8 The above-mentioned encapsulated motor conductive ring 100 will be further explained.

[0040] To improve the reliability of the first plastic-encapsulated barrier 40, such as Figures 2 to 4As shown, the first encapsulated barrier 40 includes a first barrier sheet 41 and a first fixing block 42. The first barrier sheet 41 is attached to the first terminal 10 and disposed between the first terminal 10 and the second terminal 20. The first fixing block 42 is installed on the first terminal 10 and connected to the first barrier sheet 41. By adopting the method of the first encapsulated barrier 40 including the first barrier sheet 41 attached to the first terminal 10 and the first fixing block 42, the first barrier sheet 41 is tightly attached to the first terminal 10 and disposed between the first terminal 10 and the second terminal 20. The first barrier sheet 41 can accurately fill the gap between the terminals and form a stable insulating isolation layer. The first fixing block 42 is connected to the first terminal 10 to fix the first barrier sheet 41, so that the first barrier sheet 41 will not be displaced due to external force during the encapsulation process, ensuring the stability of the insulation distance between the terminals, effectively solving the problem of easy displacement of traditional insulating materials, and achieving the purpose of further improving the reliability of the first encapsulated barrier 40.

[0041] To improve the manufacturing yield and lifespan of conductive rings, such as Figure 5 As shown, the first fixing block 42 includes a first limiting post 421 and a first blocking part 422. The first limiting post 421 is disposed on the first barrier plate 41 and passes through the first terminal 10 and is connected to the first blocking part 422. The first blocking part 422 is connected to the side of the first terminal 10 opposite to the first barrier plate 41. The first terminal 10 is provided with a first limiting hole 11 for the first limiting post 421 to pass through. By using the first fixing block 42 to pass through the first limiting hole 11 on the first terminal 10 and connect to the first blocking part 422 through the first limiting post 421, the first fixing block 42 forms a mechanical limiting structure that passes through the first terminal 10. The first barrier plate 41 is firmly fixed to one side of the first terminal 10 through the first fixing, so that the first plastic-encapsulated barrier 40 and the first terminal 10 form a rigid connection. During the plastic-encapsulation process, it can withstand the injection pressure without positional change, significantly enhancing the fixing strength of the first barrier plate 41, ensuring the stable insulation barrier effect between the terminals, and achieving the purpose of improving the manufacturing yield and service life of the conductive ring.

[0042] To improve the barrier stability of the first encapsulated barrier 40, such as Figure 5As shown, the first encapsulated barrier 40 also includes a first support block 43. The first support block 43 is disposed between the first barrier sheet 41 and the second terminal 20 and contacts the second terminal 20. By disposing the first support block 43 between the first barrier sheet 41 and the second terminal 20 and contacting the second terminal 20, the first support block 43 can effectively provide direct support for the second terminal 20. During the encapsulation process, the first support block 43 can withstand the injection pressure on the second terminal 20, preventing the second terminal 20 from shifting towards the first terminal 10, thereby maintaining the preset interval distance between the terminals and preventing the risk of conduction caused by the reduction of the terminal spacing, thus achieving the purpose of improving the barrier stability of the first encapsulated barrier 40.

[0043] To improve the anti-interference capability of the overall structure of the conductive ring, such as Figure 5 As shown, the first encapsulated barrier 40 also includes an auxiliary support block 44. The auxiliary support block 44 is disposed between the first terminal 10 and the third terminal 30, and passes through the first terminal 10 to connect with the first barrier sheet 41. By using the auxiliary support block 44 to be disposed between the first terminal 10 and the third terminal 30 and to pass through the first terminal 10 to connect with the first barrier sheet 41, a bridging support structure is formed between the first terminal 10 and the third terminal 30. The auxiliary support block 44 not only enhances the connection strength between the first encapsulated barrier 40 and the first terminal 10, but also provides indirect support for the third terminal 30, balancing the external force on the third terminal 30 during the encapsulation process, preventing the third terminal 30 from shifting due to uneven force, ensuring the stability of the insulation interval between the terminals, and achieving the purpose of improving the anti-interference capability of the overall structure of the conductive ring.

[0044] To improve the stability and reliability of the first plastic-encapsulated barrier 40, such as Figure 5 As shown, the auxiliary support block 44 includes an auxiliary blocking part 441 and an auxiliary limiting post 442. The auxiliary blocking part 441 is disposed between the first terminal 10 and the third terminal 30. The auxiliary limiting post 442 passes through the first terminal 10 and connects to the first barrier piece 41. By using the auxiliary limiting post 442 of the auxiliary support block 44 to pass through the first terminal 10 and connect to the first barrier piece 41, and by disposing the auxiliary blocking part 441 between the first terminal 10 and the third terminal 30, the auxiliary support block 44 and the first fixing block 42 form a double limiting on the first barrier piece 41, so that the first plastic-encapsulated barrier piece 40 can be firmly fixed on the first terminal 10, and stably support the third terminal 30 during the plastic-encapsulation process, preventing the third terminal 30 from moving towards the first terminal 10, effectively maintaining the insulation distance between the terminals, and further improving the stability and reliability of the first plastic-encapsulated barrier piece 40.

[0045] To improve the manufacturing yield and performance of conductive rings, such as Figure 5and Figure 7 As shown, the auxiliary support block 44 also includes an auxiliary support part 443. The auxiliary support part 443 is disposed between the first terminal 10 and the third terminal 30 and contacts the third terminal 30. By disposing the auxiliary support part 443 between the first terminal 10 and the third terminal 30 and contacting the third terminal 30, a direct physical support point is provided for the third terminal 30. During the molding process, the auxiliary support part 443 can withstand the injection pressure on the third terminal 30, preventing the third terminal 30 from shifting or tilting, ensuring the stability of the insulation gap between the third terminal 30 and the first terminal 10, thereby effectively preventing the terminals from conducting and achieving the purpose of improving the manufacturing yield and performance of the conductive ring.

[0046] To improve the overall structural stability and insulation reliability of the conductive ring, such as Figure 6 and Figure 8 As shown, the second encapsulated barrier 50 includes a second barrier sheet 51 and a second fixing block 52. The second barrier sheet 51 is attached to the first terminal 10 and disposed between the first terminal 10 and the third terminal 30. The second fixing block 52 is installed on the first terminal 10 and connected to the second barrier sheet 51. By attaching the second barrier sheet 51 of the second encapsulated barrier 50 to the first terminal 10 and disposing it between the first terminal 10 and the third terminal 30, an insulating barrier structure symmetrical to the first encapsulated barrier 40 is formed. The second fixing block 52 fixes the second barrier sheet 51, so that the second barrier sheet 51 is stably maintained in position during the encapsulation process, ensuring that the insulation distance between the third terminal 30 and the first terminal 10 is not disturbed by external forces. The symmetrical structural design can balance the forces between the terminals, thereby improving the overall structural stability and insulation reliability of the conductive ring.

[0047] To improve the manufacturing yield and reliability of conductive rings, such as Figure 6 and Figure 8As shown, the second fixing block 52 includes a second limiting post 521 and a second blocking part 522. The second limiting post 521 is disposed on the second barrier piece 51 and passes through the first terminal 10 and is connected to the second blocking part 522. The second blocking part 522 is connected to the side of the first terminal 10 opposite to the second barrier piece 51. The first terminal 10 is provided with a second limiting hole 12 for the second limiting post 521 to pass through. By using the second fixing block 52 to pass through the second limiting hole 12 on the first terminal 10 and connect to the second blocking part 522, the second fixing block 52 forms a mechanical limiting structure symmetrical with the first fixing block 42. The second barrier piece 51 is firmly fixed to one side of the first terminal 10 by the second fixing block 52, so that a rigid connection is formed between the second encapsulated barrier piece 50 and the first terminal 10. During the encapsulation process, it can withstand the injection pressure without positional change, ensuring the stable insulation barrier effect between the third terminal 30 and the first terminal 10, thereby improving the manufacturing yield and reliability of the conductive ring.

[0048] To improve the stability and reliability of the second encapsulated barrier 50 and ensure the insulation performance of the overall conductive ring structure, such as... Figure 6 and Figure 8 As shown, the second encapsulated barrier 50 also includes a second support block 53. The second support block 53 is disposed between the second barrier sheet 51 and the third terminal 30, and contacts the third terminal 30. By disposing of the second support block 53 between the second barrier sheet 51 and the third terminal 30 and contacting the third terminal 30, the second support block 53 supports the third terminal 30. During the encapsulation process, the second support block 53 can withstand the injection pressure on the third terminal 30, preventing the third terminal 30 from shifting towards the first terminal 10, thereby maintaining the preset spacing between the terminals and preventing the risk of continuity due to the reduction of the terminal spacing. This improves the stability and reliability of the second encapsulated barrier 50 and ensures the insulation performance of the overall conductive ring structure.

[0049] The manufacturing method of the encapsulated motor conductive ring 100 provided in this application is as follows: First, a first encapsulated barrier 40 and a second encapsulated barrier 50 are injection molded onto the first terminal 10. Then, the first terminal 10, on which the first encapsulated barrier 40 and the second encapsulated barrier 50 are injection molded, is placed into a mold, and the first support block 43 of the first encapsulated barrier 40 abuts against the second terminal 20, and the second support block 53 of the second encapsulated barrier 50 abuts against the third terminal 30, in conjunction with the auxiliary support block 44. The auxiliary support part 443 forms a three-way support structure for the second terminal 20 and the third terminal 30. During the molding process, the first molding barrier 40 and the second molding barrier 50 cooperate to effectively resist the injection pressure and mold closing vibration. A molding disc 60 is formed by injection molding on the first terminal 10, the second terminal 20, the third terminal 30, the first molding barrier 40 and the second molding barrier 50, thereby fixing the first terminal 10, the second terminal 20 and the third terminal 30 together to form a molded motor conductive ring 100.

[0050] 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.

[0051] 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.
