Therefore, they should not be construed as limiting the scope of protection of this utility model. The embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] It should be understood that the accompanying drawings are for illustrative purposes only.

[0020] A conductive device, such as Figures 1-8 As shown, it includes a fixing member 1 and a conductive fiber bundle 2 disposed on the fixing member 1. A first mounting hole 121 is provided on the fixing member 1, and the conductive fiber bundle 2 is inserted into the first mounting hole 121. A bracket 13 is also provided on the fixing member 1, and a second mounting hole 131 is provided on the bracket 13.

[0021] The conductive fiber bundle 2 can be linear or U-shaped. In this embodiment, the conductive fiber bundle 2 is U-shaped and inserted into two adjacent first mounting holes 121. The conductive fiber bundle 2 includes a first protrusion, a second protrusion, and a connecting portion. The first and second protrusions are located on the same side of the connecting portion. When the first protrusion passes through the first mounting hole 121, the second protrusion also passes through the adjacent first mounting hole 121. When the first protrusion passes through the second mounting hole 131, the second protrusion also passes through the adjacent second mounting hole 131. If the fixing member 1 is annular or semi-circular, the first and second protrusions extend towards the axis of the fixing member 1. If the fixing member 1 is rectangular or square, the first and second protrusions extend along their length direction to facilitate conductive connection with external rotating or fixed components and achieve stable transmission of current or signals. The length of the conductive fiber bundle 2 is cut using a die.

[0022] The fastener 1 includes a first fixing part 11 and a second fixing part 12. The first fixing part 11 is arranged axially along the first mounting hole 121, and the second fixing part 12 is arranged radially along the first mounting hole 121. The first mounting hole 121 is disposed on the second fixing part 12. One end of the first fixing part 11 is connected to one end of the second fixing part 12, and the connection between the second fixing part 12 and the first fixing part 11 is provided with an arc transition to reduce structural concentration and improve the overall structural strength of the fastener 1. Furthermore, the bottom surface of the first fixing part 11 is higher than the bottom surface of the second fixing part 12. The second fixing part 12 is arc-connected to the first fixing part 11, and the arc connection protrudes toward the upper end of the second fixing part 12 to increase the strength of the fastener 1. The fact that the bottom surface of the first fixing part 11 is higher than the bottom surface of the second fixing part also allows the second mounting hole 131 to be disposed closer to the fixed end of the bracket, making the bracket stronger and preventing damage to the second mounting hole 131 when the bracket is pressed down. After the conductive fiber bundle 2 is placed, the conductive fiber bundle 2 does not come into contact with the arc-shaped connection.

[0023] A clearance groove 122 is provided on the outer side of the second fixing part 12. The clearance groove 122 is arranged around the outer periphery of the second fixing part 12 to ensure that the installation position of the conductive fiber bundle 2 in the circumferential direction is uniform, and further ensures the consistency of the product's conductivity. The first mounting hole 121 is opened in the clearance groove 122. After the conductive fiber bundle 2 is inserted, the connecting part is located in the clearance groove 122, providing sufficient installation space for the conductive fiber bundle 2, avoiding interference or damage to the conductive fiber bundle 2 by the structure or device outside the second fixing part 12, and facilitating the insertion of the conductive fiber bundle 2, thereby improving assembly efficiency.

[0024] The bracket 13 is disposed at the end of the first fixing part 11 away from the second fixing part 12. The bracket 13 is radially arranged along the first mounting hole 121 and protrudes from the first fixing part 11. The second mounting hole 131 is disposed near the fixing end of the bracket 13. The second mounting hole 131 corresponds to the first mounting hole 121 on the second fixing part 12. The conductive fiber bundle 2 passes through the first mounting hole 121 and the second mounting hole 131 in sequence to achieve preliminary positioning. After the conductive fiber bundle 2 is placed, the entire conductive fiber bundle 2 is on the same plane.

[0025] After the conductive fiber bundle 2 passes through the first mounting hole 121 and the second mounting hole 131 in sequence, the external device presses down on the bracket 13 toward the conductive fiber bundle 2. The free end of the bracket 13 presses the conductive fiber bundle 2 tightly onto the fixing member 1. When the free end of the bracket 13 is pressed down, the fixed end of the bracket 13 with the second mounting hole 131 still maintains the radial orientation of the second mounting hole 131. Furthermore, when the bracket 13 is pressed down, the free end of the bracket 13 is pressed into a pressing part extending axially toward the second mounting hole 131. A pressing space is formed between the pressing part and the first fixing part 11. After the conductive fiber bundle 2 passes through the second mounting hole 131, it is located in the pressing space. The pressing part tightly presses the conductive fiber bundle 2 into the pressing space to prevent the conductive fiber bundle 2 from moving.

[0026] The pressing part is positioned towards the second fixing part 12. Since the conductive fiber bundle 2 has no support at the bottom after extending out of the second mounting hole 131, it avoids deformation of the conductive fiber bundle 2 when the bracket 13 extends out of the first fixing part 11 and presses the conductive fiber bundle 2.

[0027] By applying a downward force to the free end of the bracket 13, the free end of the bracket 13 is pressed, creating a clamping force on the conductive fiber bundle 2, thus stably pressing the conductive fiber bundle 2 onto the fixing member 1. By directly pressing the bracket 13 onto the fixing member 1, the resistivity fluctuation problem caused by uneven pressure and poor contact during the separate pressing process is effectively avoided, ensuring stable and reliable conductivity. At the same time, the assembly step of the separate bracket 13 is eliminated; the pressing and installation of the conductive fiber bundle 2 can be completed simply by inserting and pressing the bracket 13, significantly reducing installation steps, assembly difficulty, and labor costs.

[0028] In this solution, to avoid the conductive fiber bundle 2 being scratched or rubbed after the support 13 is pressed down, the support 13 is rounded to reduce scratching or friction.

[0029] A buffer groove 111 is provided on the first fixing part 11. The position of the buffer groove 111 corresponds to the arrangement path of the conductive fiber bundle 2. After the conductive fiber bundle 2 passes through the first mounting hole 121 and the second mounting hole 131 in sequence, the conductive fiber bundle 2 is located above the buffer groove 111. The buffer groove 111 provides buffer protection for the conductive fiber bundle 2, preventing deformation and damage when the conductive fiber bundle 2 is squeezed after the support 13 is pressed down, or deformation caused by squeezing and friction during assembly and use. It also positions the conductive fiber bundle 2. Of course, because there is an arc-shaped transition connecting part between the first fixing part 11 and the second fixing part 12, and the arc-shaped transition is lower than the first fixing part 11, if the buffer groove 111 is not provided, the conductive fiber bundle 2 is prone to deformation or damage at the arc-shaped transition part when it is squeezed, impacted or vibrated. Therefore, the buffer groove 111 is provided on the first fixing part 11.

[0030] To achieve high manufacturing precision and low scrap rate for the conductive device, in this solution, the fixing component 1 and the bracket 13 are integrally formed. Furthermore, the fixing component 1 and the bracket 13 are stamped, which not only ensures the consistency and precision of the product structure, but also simplifies the processing flow, improves production efficiency, facilitates mass production, and ensures the connection strength between the bracket 13 and the fixing component 1.

[0031] The bracket 13 is a portion protruding from the first fixing part 11. When the stamping is just completed, the bracket 13 is arranged axially along the first mounting hole 121. When the bracket 13 is bent and shaped, the bracket 13 arranged axially along the first mounting hole 121 is bent to be arranged radially along the first mounting hole 121. In order to prevent the first fixing part 11 from deforming except for the bracket 13 when the bracket 13 is bent and shaped, stress gaps 112 are opened on both sides where the bracket 13 and the first fixing part 11 are connected. The stress gaps 112 are arranged axially along the first mounting hole 121. In this solution, the length of the stress gaps 112 does not exceed the thickness of the bracket 13.

[0032] The material of the fastener 1 is a conductive material, including but not limited to aluminum, iron, copper, carbon fiber, and graphite.

[0033] The fixing member 1 can be configured as a ring, rectangle, or semicircle, etc. In this solution, the fixing member 1 is configured as a ring, the axial direction of the fixing member 1 is the radial direction of the first mounting hole 121, and the radial direction of the fixing member 1 is the axial direction of the first mounting hole 121.

[0034] The size of the fixing member 1 can be adjusted as needed to ensure compatibility with different motors. Simultaneously, the number of the first mounting holes 121 on the fixing member 1 and the second mounting holes 131 on the bracket 13 can also be adjusted.

[0035] An assembly process for a conductive device is as follows: After the fastener 1 is stamped and integrally formed, the bracket 13, which is axially arranged along the first mounting hole 121, is bent and shaped to be radially arranged along the first mounting hole 121. Then, the free end of the conductive fiber bundle 2 is passed through the first mounting hole 121 on the second fixing part 12 and the second mounting hole 131 on the bracket 13 in sequence. Then, external equipment is used to press and rivet the free end of the bracket 13 towards the conductive fiber bundle 2. After pressing, the free end of the bracket 13 and the conductive fiber bundle 2 form a stable clamping state. Check the installation position and clamping degree of the conductive fiber bundle 2 to ensure that the requirements are met and complete the assembly of the conductive device.

[0036] This utility model mainly designs a conductive device that uses a pressing bracket 13 to press and fix the conductive fiber bundle 2, eliminating the need for the pressing process of a separate bracket, reducing installation steps, and simplifying processing and assembly. At the same time, the contact and pressing state between the bracket 13 and the conductive fiber bundle 2 is stable, ensuring that the resistivity of the conductive device is stable and uniform, which is beneficial for mass production. It can be widely used in equipment such as motors, generators, and sensors that require conductive connections between rotating and stationary components.

However, the present invention is not limited to the specific details of the above embodiments.

[0038] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.
