Description

Technical Field

[0001] This utility model relates to the field of motor bus ring technology, and in particular to a motor bus ring and terminal connection structure. Background Technology

[0002] The bus ring is an important component in the motor. The bus ring and the terminal need to be connected. At this time, the bus ring and the terminal need to be positioned. However, after the connection is completed, the terminal may deviate from the intended position.

[0003] For example, on September 6, 2024, a publication with the publication number CN116114150B was disclosed, which discloses a bus ring terminal, a slip ring, and a motor. The bus ring terminal is used to connect to the lead-out end of the bus ring of the motor. The bus ring terminal includes a body and a connecting portion located at one end of the body. The connecting portion is used to surround the lead-out end at least in the circumferential direction, so that the bus ring terminal can be positioned relative to the lead-out end in the radial and circumferential directions of the bus ring. However, the applicant found that if the solder joint is loose, the terminal may move along the radial direction of the bus ring on the lead-out end, and the positioning accuracy is not accurate enough. Summary of the Invention

[0004] In view of this, the purpose of this utility model is to propose a motor bus ring and terminal connection structure to solve the problem that the terminal may move along the radial direction of the bus ring on the lead-out end, resulting in insufficient positioning accuracy.

[0005] Based on the above objectives, this utility model provides a motor bus ring and terminal connection structure, including a connection end disposed on the bus ring. The connection end includes an upper connection portion and a lower connection portion, and a stop portion is disposed between the upper connection portion and the lower connection portion. The width of the stop portion is greater than the width of the upper connection portion and the width of the lower connection portion. A terminal body is connected to the connection end. The terminal body includes a terminal body, and conductor crimping portions are disposed on both sides of the middle portion of the terminal body. The conductor crimping portions are used to surround the upper connection portion in the circumferential direction, so that the terminal body can be connected to the connection end in the circumferential direction of the bus ring. Two insulating crimping portions connected to the terminal body are disposed below the conductor crimping portions. The insulating crimping portions are used to surround the lower connection portion in the circumferential direction, so that the terminal body can be connected to the connection end in the circumferential direction of the bus ring. A gap groove is disposed between the conductor crimping portions and the insulating crimping portions for cooperating with the stop portion.

[0006] Optionally, the two conductor crimp portions are arranged symmetrically about the terminal body.

[0007] Optionally, the two insulating crimp portions are arranged symmetrically at the center, with one insulating crimp portion located diagonally above the other insulating crimp portion.

[0008] Optionally, the terminal body can be strip-shaped.

[0009] Optionally, the stop portion includes two protruding blocks.

[0010] Optionally, the terminal body is provided with a through hole, and the connecting end is provided with a protruding post that penetrates the through hole.

[0011] Optionally, one end of the insulating crimping portion is used to abut against the stop portion in the axial direction of the connecting end, and the other end of the insulating crimping portion is used to abut against the connecting end in the axial direction, so that the terminal body can be positioned and restricted relative to the connecting end in the axial direction.

[0012] Optionally, the upper connecting part and the lower connecting part are elastically bent structures.

[0013] Optionally, both the conductor crimping portion and the insulating crimping portion include a surrounding portion, which is used to circumferentially encircle the connecting end.

[0014] Optionally, the surrounding portion is C-shaped in a cross-section perpendicular to the axial direction of the bus ring.

[0015] The beneficial effects of this utility model are as follows: The motor bus ring and terminal connection structure provided by this utility model has a simple connection structure between the bus ring and the terminal body, high process operability, lower part cost, convenient and accurate positioning of the bus ring and the terminal body. If the welding joint between the bus ring and the terminal body becomes loose, the stop part will restrict the terminal body from moving along the radial direction of the bus ring on the connection end, thereby improving the positioning accuracy. The conductor crimping part is crimped with the upper connection part on the connection end, and the insulation crimping part is crimped with the lower connection part on the connection end. After the crimping is completed, the contact area can be greatly increased, the contact resistance can be reduced, the current density of the terminal contact part can be reduced, and the normal current flow can be maintained.

[0024] like Figures 1 to 4As shown, a motor bus ring and terminal connection structure includes a connecting end 8 disposed on a bus ring 6. The connecting end 8 includes an upper connecting portion 9 and a lower connecting portion 10. A stop portion 11 is disposed between the upper connecting portion 9 and the lower connecting portion 10. The width of the stop portion 11 is greater than the width of the upper connecting portion 9 and the width of the lower connecting portion 10. A terminal body 1 is connected to the connecting end 8.

One end of each guide vane 7 is provided with a welding hook for connecting to the enameled wire of the motor, and the other end of each guide vane 7 is provided with a connecting end 8 for connecting to the terminal body 1. The terminal body 1 includes a terminal body 2. Conductor crimping portions 3 are provided on both sides of the middle part of the terminal body 2. The conductor crimping portions 3 are used to surround the upper connecting portion 9 in the circumferential direction, so that the terminal body 1 can be connected to the connecting end 8 in the circumferential direction of the bus ring 6. Two insulating crimping portions 4 are provided below the conductor crimping portions 3 and connected to the terminal body 2. The insulating crimping portions 4 are used to surround the lower connecting portion 10 in the circumferential direction, so that the terminal body 1 can be connected to the connecting end 8 in the circumferential direction of the bus ring 6. A gap groove 5 is provided between the conductor crimping portions 3 and the insulating crimping portions 4 for cooperating with the stop portion 11.

[0025] The connection structure between the bus ring 6 and the terminal body 1 is simple, the process is highly operable, and the component cost is lower. The positioning of the bus ring 6 and the terminal body 1 is convenient and accurate. If the welding joint between the bus ring 6 and the terminal body 1 becomes loose, the stop part 11 will restrict the terminal body 1 from moving radially along the bus ring 6 on the connection end 8, thereby improving the positioning accuracy. The conductor crimping part 3 is crimped with the upper connecting part 9 on the connection end 8, and the insulation crimping part 4 is crimped with the lower connecting part 10 on the connection end 8. After the crimping is completed, the contact area can be greatly increased, the contact resistance can be reduced, the current density of the terminal contact part can be reduced, and the normal current flow can be maintained.

[0026] The two conductor crimping portions 3 are arranged symmetrically about the terminal body 2.

[0029] The stop portion 11 includes two protruding blocks, which can effectively increase the pull-out force of the terminal body 1 after it is pressed against the connection end 8.

[0030] The terminal body 2 is provided with a through hole, and the connecting end 8 is provided with a protruding post that passes through the through hole to facilitate further positioning.

[0031] One end of the insulating crimping part 4 is used to abut against the stop part 11 in the axial direction of the connecting end 8, and the other end of the insulating crimping part 4 is used to abut against the connecting end 8 in the axial direction, so that the terminal body 1 can be positioned and restricted relative to the connecting end 8 in the axial direction.

[0032] The upper connecting part 9 and the lower connecting part 10 are elastically bent structures, ensuring that the upper connecting part 9 can be pressed tightly against the conductor pressing part 3 after crimping, and the lower connecting part 10 can be pressed tightly against the insulating pressing part 4 after crimping.

[0033] Both the conductor crimping part 3 and the insulating crimping part 4 include a surrounding part, which is used to surround the connecting end 8 in the circumferential direction. The conductor crimping part 3 is crimped with the upper connecting part 9 on the connecting end 8, and the insulating crimping part 4 is crimped with the lower connecting part 10 on the connecting end 8. After crimping, the contact area can be greatly increased, the contact resistance can be reduced, and the current density of the terminal contact part can be reduced.

[0034] The surrounding portion is C-shaped in a cross section perpendicular to the axial direction of the busbar ring 6.
