[0026] Schematic diagram of a commutator with a packing that is not easy to fall off

[0027] refer to Figure 1 to Figure 2According to a preferred embodiment of the utility model, the filler 20 is not easy to fall off the commutator, wherein it should be noted that the above-mentioned new commutator is used for a motor, wherein the commutator includes a plurality of commutator segments 10, and the plurality of commutator segments 10 are arranged in a ring array. In addition, it should be noted that the commutator segments 10 of the utility model are preferably three. In addition, a filler 20 is arranged between the plurality of commutators, and the filler 20 is integrally formed by injection molding.

[0028] It is worth mentioning that the plurality of commutator segments 10 together form a first opening 101 , a cavity and a second opening 102 . The first opening 101 and the second opening 102 are both connected to the cavity, and the filler 20 is used to fill the cavity.

[0029] It should be noted that the sides of the multiple commutator segments 10 facing away from each other each have a first bent portion 11, the first bent portion 11 is integrally formed with the end of the commutator segment 10, and the multiple first bent portions 11 are also close to the first opening 101. In addition, the sides of the multiple commutator segments 10 close to each other each have a second bent portion 12, the second bent portion 12 is integrally formed with the commutator segment 10, and the multiple second bent portions 12 are close to the second opening 102. It is worth mentioning that the multiple second bent portions 12 are configured to increase the bonding force between the commutator segment 10 and the filler 20, but our company's previous commutator structure is as follows Figure 3 As shown in FIG. 1 , the binding force between the hook commutator segment 10 and the filler 20 mainly relies on the dovetail body on the inner side of the commutator segment 10. However, in actual application, the structural force between the commutator segment 10 and the filler 20 of the commutator using this structural design is poor, which leads to poor overspeed performance of the commutator. Therefore, our company has improved the previous dovetail body structure, as shown in FIG. Figure 2 shown.

[0030] It is worth mentioning that the spacing between the dovetail structure and the commutator segment 10 of our company is relatively small, resulting in a smaller contact surface between the dovetail structure and the filler 20, while the bending amplitude of the original dovetail structure is increased in the present invention. Figure 2The second curved portion 12 shown in the figure improves the bonding force between the commutator segment 10 and the filler 20, and the commutator segment 10 is a copper part, so the structural strength at the second curved portion 12 is also increased. Specifically, the commutator in which the filler 20 is not easy to fall off further includes at least one reinforcing sheet 30, which is arranged between the second curved portion 12 and the commutator segment 10, that is, one end of the reinforcing sheet 30 is connected to the side of the second curved portion 12 close to the commutator segment 10, and the other end is connected to the side of the commutator segment 10 close to the second curved portion 12. Specifically, the reinforcing sheet 30 is connected to the second curved portion 12 by welding, and the reinforcing sheet 30 is also connected to the commutator segment 10 by welding, so that the structural strength of the second curved portion 12 and the commutator segment 10 is improved by the reinforcing sheet 30.

[0031] It should be noted that the reinforcing sheet 30 also has a waist-shaped groove 301, and the waist-shaped groove 301 runs through the reinforcing sheet 30. When the filler 20 is injected, the filler 20 will pass through the waist-shaped groove, thereby improving the bonding force between the reinforcing sheet 30 and the filler 20.

[0032] Furthermore, the reinforcing sheet 30 is located in the middle section of the second curved portion 12, and the second curved portion 12 has two first notches 1201, both of which penetrate the second curved portion 12, and the two first notches 1201 are respectively located on both sides of the reinforcing sheet 30. It is worth mentioning that one of the walls forming the first notch 1201 also has a third curved portion 13, the third curved portion 13 extends a predetermined distance in a direction away from the waist-shaped groove 301, and the first notch 1201 is processed and formed by an external cutting device, and at the same time, the wall surface of the second curved portion 12 facing the first notch 1201 can be extruded by an extrusion tool to form the third curved portion 13, that is, after the filler 20 is injection-molded, the third curved portion 13 is used to improve the bonding force between the second curved portion 12 and the filler 20, thereby improving the overspeed performance of the utility model.

[0033] Furthermore, the commutator in which the filler 20 is not easy to fall off also includes a ring 40, and the multiple second curved portions 12 are all matched with the ring 40, and then the positions of the multiple commutator segments 10 are limited by the above-mentioned ring 40, so as to facilitate the subsequent injection molding of the filler 20. In addition, each of the reinforcing sheets 30 has a second notch 302 at one end away from the waist-shaped groove 301, and the ends of the ring 40 are matched with the multiple second notches 302, so as to limit the position of the ring 40 by the multiple second notches 302. In addition, the center of the ring 40 also has an insertion hole 401, and the insertion hole 401 passes through the ring 40, and the ends of the multiple second curved portions 12 are all placed in the insertion hole 401. It is worth mentioning that the ring 40 is also configured to improve the structural strength between the second curved portion 12 and the commutator segment 10.

[0034] In summary, the commutator with filler that is not easy to fall off based on the embodiment of the present application is explained, which provides the commutator with filler that is not easy to fall off with the advantages of good bonding force between the commutator segments and the filler, high connection strength, high practicality, and filler that is not easy to fall off.

[0035] It is worth mentioning that in the embodiment of the present application, the commutator with filler that is not easy to fall off has a simple structure, does not involve complex manufacturing processes and expensive materials, and has high economic efficiency. At the same time, for manufacturers, the commutator with filler that is not easy to fall off provided by the present application is easy to produce and has low cost, which is more conducive to controlling production costs and further conducive to product promotion and use.
