[0002] The commutator is an important component of the armature of DC motors and AC commutator motors. Its main structure consists of multiple commutator copper plates mounted on a commutator body. Each commutator copper plate is connected to several armature winding elements through wires.

[0027] Schematic illustration of a commutator with multiple bends for easy winding, see reference. Figures 2 to 5 According to a preferred embodiment of the present invention, a multi-hook commutator for easy winding includes a bakelite powder body 10, an insulating ring 20, and a fixing component 30 for fixing the position of the insulating ring 20.
[0028] Specifically, such as Figures 2 to 4As shown, the bakelite powder body 10 is arranged in a ring array with a plurality of first commutator segments 40 and a plurality of second commutator segments 50. A second commutator segment 50 is provided between two adjacent first commutator segments 40. The first commutator segment 40 includes a first contact 401 and a first hook portion 402. The second commutator segment 50 includes a second contact 501 and a second hook portion 502. The first contact 401 is embedded in the bakelite powder body 10, and each first hook portion 402 is fixedly connected to one end of the corresponding first contact 401. Each second hook portion 502 is slidably disposed on the corresponding second contact 501. In addition, the outer wall of the insulating ring 20 has a plurality of extension ends 201, each extension end 201 corresponding to a second hook portion 502. Each extension end 201 is fixedly connected to a corresponding second hook portion 502. The insulating ring 20 is slidably disposed on the bakelite powder body 10.
[0029] It should be noted that the position of the first hook portion 402 is fixed relative to the bakelite powder body 10 under normal conditions, while the position of the second hook portion 502 relative to the bakelite powder body 10 can move back and forth in the axial direction. This allows the soldering operator to pull out each second hook portion 502 a certain length before soldering an external wire to the second hook portion 502. Since the second hook portion 502, after being pulled out a certain length, is staggered from the first hook portion 402 in the length direction of the bakelite powder body 10, and a first hook portion 402 is provided between each adjacent second hook portion 502, the included angle between adjacent second hook portions 502 is relatively smaller than that between the first and second hook portions 402. The angle between the first second hook portion 502 and the adjacent first hook portion 402 is larger, thus providing more clearance space so that the soldering personnel can wrap the wire around the second hook portion 502 and solder it. Similarly, after the soldering personnel electrically connect each second hook portion 502, each second hook portion 502 can be moved back one end along the axial direction of the bakelite powder body 10, so that the second hook portion 502 and the first hook portion 402 are again staggered in the length direction of the bakelite powder body 10. However, at this time, the first hook portion 402 is in front and the second hook portion 502 is behind. At this time, the soldering personnel can solder the external wire to the first hook portion 402. It is evident that, compared to the prior art where the position of the hook portion is fixed relative to the bakelite powder body 10, when the number of commutator segments is large, the included angle between two adjacent hook portions is small, the clearance space is small, which is not conducive to winding and soldering. This application achieves the advantages of staggered distribution of hook portions during winding, which facilitates winding and is suitable for multiple hooks by sliding half of the hook portion.
[0030] It should also be noted that when the second hook portion 502 is slidable, the fixing component 30 must first be removed; and after each of the first hook portions 402 and the second hook portions 502 is soldered, the soldering personnel then fix the fixing component 30 to the bakelite powder body 10 to fix the position of the second hook portion 502.
[0031] It should also be noted that by setting the insulating ring 20, each of the second hook portions 502 moves synchronously, which helps to improve efficiency.
[0032] Furthermore, to enable the second hook portion 502 to slide on the second contact member 501, such as... Figure 3 and Figure 5 As shown, the insulating ring 20 is slidably disposed on the bakelite powder body 10. One end of the bakelite powder body 10 has a plurality of first grooves 101 and second grooves 102. The center of the bakelite powder body 10 has a first through hole 103. Each second contact 501 has a third groove 5011 at one end near the second hook portion 502. The two sides of the second groove 102 are respectively connected to the first groove 101 and the first through hole 103. The first groove 101 extends from one end of the bakelite powder body 10 toward the second contact 501 and is connected to the third groove 5011. The insulating ring 20 is slidably disposed in the first through hole 103, and the extended end 201 passes through the second groove 102 and extends into the first groove 101. One end of the second hook portion 502 extends into the third groove 5011, and the side wall of the second hook portion 502 is in contact with the side wall of the third groove 5011.
[0033] It should be noted that, under normal conditions, when the fixing component 30 fixes the position of the second hook portion 502, one end of the second hook portion 502 is located in the middle section of the third slide groove 5011, so that no matter whether the soldering personnel pull the second hook portion 502 forward or slide it backward, the side wall of the second hook portion 502 is in contact with the side wall of the third slide groove 5011. It should also be added that the first contact 401, the first hook portion 402, the second contact 501, and the second hook portion 502 are all made of conductive materials. This is why it is necessary to ensure that the side wall of the second hook portion 502 is in contact with the side wall of the third slide groove 5011, and why the insulating ring 20 is made of insulating material. It should also be noted that if the insulating ring 20 is made of insulating material, the fixed connection between the insulating ring 20 and the second hook portion 502 includes, but is not limited to, screw connection. Each screw passes through the second hook portion 502 and is threadedly connected to the insulating ring 20, and adjacent screws do not contact each other.
[0034] It should also be noted that when the soldering operator wants to slide the position of the second hook portion 502, after removing the fixing component 30, it is only necessary to move the insulating ring 20 along the first through hole 103, and each of the extension ends 201 and the second hook portion 502 will follow the insulating ring 20 and move relative to the second slide groove 102 and the third slide groove 5011 respectively.
[0035] Furthermore, to ensure that the second hook portion 502 is normally fixed during daily use of the commutator with multiple hooks that facilitates winding, such as... Figure 5 As shown, the fixing component 30 includes a front end cover 301, a rear end cover 302, and abutment cylinder 303. The abutment cylinder 303 is placed inside the first through hole 103 and abuts against one side of the insulating ring 20. The front end cover 301 and the rear end cover 302 are located at both ends of the bakelite powder body 10 and are detachably connected to the bakelite powder body 10. The front end cover 301 is located at the end of the bakelite powder body 10 near the first contact member 401 and abuts against the other side of the insulating ring 20. The rear end cover 302 abuts against the end of the abutment cylinder 303 away from the insulating ring 20.
[0036] It should be noted that both the front end cap 301 and the rear end cap 302 are detachably connected to the bakelite powder body 10 via screws. When the second hook portion 502 needs to be pulled out, the soldering operator can remove the front end cap 301, so that the front end cap 301 no longer obstructs the insulating ring 20, allowing the insulating ring 20 to be pulled out a certain distance for winding and soldering. When the first hook portion 402 needs to be wound and soldered, the rear end cap 302 can be removed by hot soldering. It should be pointed out that the abutment cylinder 303 is movably disposed within the first through hole 103 along the axial direction of the first through hole 103. Therefore, when the rear end cap 302 no longer restricts the axial movement of the abutment cylinder 303, the soldering operator can push the insulating ring 20 toward the end of the bakelite powder body 10 away from the first hook portion 402. When the device moves, at a certain moment the insulating ring 20 contacts the abutment cylinder 303 and locks the insulating ring 20 to move further. The abutment cylinder 303 is pushed and moves a distance of the same distance until the first hook part 402 and the second hook part 502 are misaligned. At this time, the first hook part 402 is wound and soldered. After the first hook part 402 and the second hook part 502 are wound and soldered, the operator first connects the front end cover 301 to the bakelite powder body 10, and then pushes the abutment cylinder 303 to the bottom, that is, the abutment cylinder 303 pushes the insulating ring 20 to abut against the front end cover 301. Then the rear end cover 302 is connected to the bakelite powder body 10.
[0037] Furthermore, to prevent metal debris generated by wear between the first commutator segment 40 and the adjacent second commutator segment 50 from interconnecting, such as... Figure 2 As shown, the outer wall of the bakelite powder body 10 has a plurality of partition grooves 104, and a partition groove 104 is provided between the first commutator 40 and the second commutator 50.
[0038] Furthermore, such as Figure 3 As shown, both the first contact 401 and the second contact 501 have an embedding portion 4011 on their bottom surfaces, and the embedding portion 4011 has a plurality of through grooves 4012. The bakelite powder body 10 is integrally injection molded, and the bakelite powder fills the through grooves 4012. After the bakelite powder is formed, the embedding portion 4011 is embedded in the bakelite powder body 10.
[0039] In addition, such as Figure 3 As shown, the front end cover 301, the abutment cylinder 303 and the rear end cover 302 each have a second through hole 3011, and the first through hole 103 and the second through hole 3011 are arranged coaxially.
[0040] In summary, the commutator for multiple hooks that is easy to wind, based on the embodiments of this application, is explained, which provides advantages such as the hook portions being staggered during winding, facilitating winding, and being suitable for multiple hooks.
[0041] It is worth mentioning that, in the embodiments of this application, the commutator with multiple bends and easy winding has a simple structure, does not involve complex manufacturing processes or expensive materials, and has high economic efficiency. At the same time, for manufacturers, the commutator with multiple bends and easy winding provided in this application is easy to produce and has low cost, which is more conducive to controlling production costs and further facilitates product promotion and use.
