[0042] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0043] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] The terms "first," "second," "third," "fourth," etc. (if present) in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0045] In this application, the terms "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0046] In the description of the embodiments of this application, it should be understood that the terms "inner", "outer", "upper", "bottom", "front", "rear", etc., indicate the orientation or positional relationship (if any) based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0047] In the prior art, the motor is equipped with a coil and a brush holder. One end of the brush holder is soldered to the coil by silver-copper soldering, and the other end of the brush holder is connected to the coil in other locations.

[0048] Because the coil and brush holder are connected by welding, there may be a cold solder joint. A cold solder joint will cause the current path to be blocked, forming local resistance, which will cause the temperature at the cold solder joint to rise, resulting in the cold solder joint being burned out and affecting the working efficiency of the motor.

[0049] Furthermore, during the use of the motor, vibration is inevitable due to external factors or other influences. The welding joint between the coil and the brush holder will be further weakened by external forces, resulting in a loose connection at the welding joint. Therefore, the welding method is not an stable way to connect the coil and the brush holder.

[0050] To prevent the coil from disconnecting from the brush holder, this application employs a connector to link the coil and the brush holder, thereby improving the stability of the connection between them. The following description, in conjunction with the accompanying drawings, further illustrates this application.

[0051] in, Figure 1 This is a structural schematic diagram of a motor brush holder provided in this application. Figure 2 for Figure 1 A schematic diagram of the structure of the first connecting block. Figure 3 This is a top view of a brush holder wiring structure provided in this application. Figure 4 The left view of a brush holder wiring structure provided in this application.

[0052] like Figure 1 and Figure 4 As shown, this application provides a brush holder wiring structure, including a body 100, which includes a first connecting block 110, a connector 120, a second connecting block 130, and a locking member 140.

[0053] The first connecting block 110 and the second connecting block 130 are respectively disposed at both ends of the connector 120.

[0054] The first connecting block 110 is provided with a first connecting hole 111, and the magnetic pole coil 200 is provided with a second connecting hole 210. The first connecting hole 111 and the second connecting hole 210 are connected by a locking member 140 to fix the first connecting block 110 on the magnetic pole coil 200.

[0055] The second connecting block 130 is bolted to the brush holder.

[0056] In this application, the first connecting block 110 and the magnetic pole coil 200 are fixed together by the locking member 140 to avoid the problem of the brush holder 100 and the magnetic pole coil 200 being disconnected due to poor soldering, thereby affecting the working efficiency of the motor.

[0057] Furthermore, the connection condition of the motor is usually checked during minor maintenance and major overhaul. If the connection is made by welding, it is not easy to find the poor weld during minor maintenance and major overhaul. If the 120 connector is used, it can be disassembled and inspected during minor maintenance and major overhaul, so as to update the connecting parts in time and ensure the reliability of the connection.

[0058] In this embodiment, a DC traction motor is used.

[0059] The first connecting block 110 is provided with a first connecting hole 111 corresponding to the second connecting hole 210. The locking member 140 is used to connect the first connecting hole 111 and the second connecting hole 210 together, and to fix the first connecting hole 111 and the second connecting hole 210 by means of the locking member 140.

[0060] Among them, the first connecting block 110, the second connecting block 130 and the connector 120 are all conductive components.

[0061] like Figure 2 As shown, in the embodiments provided in this application, the first connecting block 110 includes a first connecting portion 112 and a second connecting portion 113 located on one side of the first connecting portion 112.

[0062] The first connecting hole 111 is provided on the first connecting part 112.

[0063] At least a portion of the connector 120 is disposed on the side of the second connector 113 opposite to the first connector 112.

[0064] The first connecting part 112 is attached to the outer surface of the magnetic pole coil 200, and the locking member 140 is used to keep the first connecting part 112 and the magnetic pole coil 200 in a close contact state, so as to ensure that the contact surface between the first connecting part 112 and the magnetic pole coil 200 does not change, thereby avoiding the current transmission being affected by the change of the contact surface.

[0065] In the embodiments provided in this application, the first connecting block 110 further includes a bending portion 114, which is disposed between the first connecting portion 112 and the second connecting portion 113.

[0066] An L-shaped groove is formed between the bent portion 114 and both the first connecting portion 112 and the second connecting portion 113. The magnetic pole coil 200 is disposed in the L-shaped groove near the first connecting portion 112. The first connecting hole 111 is located on the bottom wall of the L-shaped groove. The side wall and top of the magnetic pole coil 200 are respectively attached to the first connecting portion 112 and the bent portion 114 to increase the transmission area between the magnetic pole coil 200 and the first connecting block 110. A portion of the connector 120 is disposed in the L-shaped groove near the second connecting portion 113. The side wall and bottom of the connector 120 are respectively attached to the second connecting portion 113 and the bent portion 114 to increase the transmission area between the connector 120 and the first connecting block 110.

[0067] The bending portion 114 effectively increases the transmission area between the connector 120 and the first connecting block 110, as well as between the magnetic pole coil 200 and the first connecting block 110, which can effectively avoid the problem of reduced transmission area and heat generation at the contact surface caused by vibration.

[0068] Combination Figure 3 and Figure 4 As shown, in the embodiments provided in this application, the connector 120 includes a braided component 121 and two connecting plates 122. The two connecting plates 122 are respectively disposed at both ends of the braided component 121, and the first connecting block 110 and the second connecting block 130 are respectively connected to the two connecting plates 122.

[0069] The braided component 121 is made of multiple wires wound together. While improving the current transmission efficiency, it ensures the connection strength between the first connecting block 110 and the second connecting block 130. It can also play a buffering role during motor vibration. Its bending stress can be released through the soft buffer structure of the flexible wire, which greatly improves the reliability and stability of the motor during operation.

[0070] The connecting plate 122 has a width of 1-2cm and is respectively set at both ends of the braided piece 121 and surrounds the braided piece 121, so that the two ends of the braided piece 121 have a certain rigidity, thereby facilitating connection with the first connecting block 110 and the second connecting block 130.

[0071] The braided part 121 is connected to the second connecting part 113 via a connecting plate 122, and the width of the connecting plate 122 is the same as the width of the second connecting part 113 to facilitate welding of the connecting plate 122 and the second connecting part 113.

[0072] In the embodiments provided in this application, the connecting plate 122 is welded to the first connecting block 110, and the connecting plate 122 is welded to the second connecting block 130.

[0073] Among them, the connecting plate 122 and the first connecting block 110 and the second connecting block 130 are all welded by silver-copper soldering.

[0074] In the embodiments provided in this application, the first connecting block 110 and the second connecting block 130 are both integrally molded parts to ensure the strength of the first connecting block 110 and the second connecting block 130.

[0075] In the embodiments provided in this application, the locking member 140 is a bolt, and at least one of the first connecting hole 111 and the second connecting hole 210 is a threaded hole.

[0076] For example, when the first connecting hole 111 is a threaded hole, the locking member 140 needs to pass through the second connecting hole 210 before being threadedly connected to the first connecting hole 111.

[0077] For example, when the second connecting hole 210 is a threaded hole, the locking member 140 needs to pass through the first connecting hole 111 before being threadedly connected to the second connecting hole 210.

[0078] For example, when both the first connecting hole 111 and the second connecting hole 210 are threaded holes, the connection sequence is not considered.

[0079] In the embodiments provided in this application, the locking member 140 is a pin, which is sequentially inserted into the first connecting hole 111 and the second connecting hole 210. The pin is fixed by static friction between itself and the first connecting hole 111 and the second connecting hole 210.

[0080] In the embodiments provided in this application, both the first connecting block 110 and the connector 120 are coated with a sealing layer. The sealing layer is used to prevent the first connecting block 110 and the connector 120 from being oxidized.

[0081] The second connecting block 130 is L-shaped, with one end connected to the connector and the other end having at least one through hole 131. The brush holder has a threaded hole corresponding to the through hole 131. The through hole 131 is connected to the threaded hole on the brush holder by bolts to fix the brush holder and the second connecting block 130.

[0082] During the process of fixing the first connecting block 110 and the magnetic pole coil 200 with the locking member 140, it is necessary to first drill the first connecting hole 111 on the magnetic pole coil 200, and apply silicone grease to the drilled first connecting hole 111 to lubricate the subsequent connection of the locking member 140. After applying the silicone grease, the hole is impregnated with paint to form an anti-oxidation layer in the first connecting hole 111.

[0083] In this application, the first connecting block is fixed to the magnetic pole coil by a locking component, which solves the problem of the brush holder and the magnetic pole coil being disconnected due to poor soldering, thereby improving the working efficiency of the motor.

[0084] Furthermore, the first connecting block and the second connecting block are connected by a braided structure. This soft buffer structure allows the bending stress during motor vibration to be released, which greatly improves the reliability and stability of the traction motor during operation.

[0085] This application also provides a motor, including a brush holder and a magnetic pole coil 200, wherein the brush holder and the magnetic pole coil 200 are provided with a brush holder connection structure as described above.
