Description

Technical Field

[0001] This application relates to the field of electronic equipment and conductive connection technology, and more specifically to a conductive ring or conductive body fixing strip that can be bent into shape for fixing a conductive body. Background Technology

[0002] In products such as rotary connectors (e.g., slip rings) and motors, conductive rings are a key structural component for achieving electrical signal connections.

[0003] Traditional conductive ring components typically use rigid and fixed-shape structural parts as the skeleton for fixing the conductor. For example, the conductive ring skeleton is made of metal or plastic through processes such as turning and milling. The conductor (such as conductive fiber) is then easily fixed by grooving, drilling, welding, etc.

[0004] Therefore, traditional conductive ring structures typically suffer from the following insurmountable drawbacks: For example, they lack flexibility and cannot adapt to non-standard curved surfaces because their rigid ring shape makes them unsuitable for applications requiring conformation to irregular surfaces or dynamic deformation. Furthermore, they are bulky and heavy, limiting precision. To ensure structural strength, the frame is usually large, hindering miniaturization and weight reduction. The cumulative assembly errors of multiple parts also significantly affect the accuracy of the conductor's position. Finally, the cumbersome assembly process and high cost are major disadvantages, resulting in low production efficiency and high labor costs due to the multiple machining and assembly steps involved.

[0005] Therefore, a technical solution is needed that is easy to process and can be easily bent to form the required shape of the conductive ring. Utility Model Content

[0006] This application provides a flexible, bendable conductive ring and conductor fixing strip: through integral molding technology, a "planar intermediate body with a pre-defined final shape potential" is created. In a two-dimensional planar state, this intermediate body can be processed with high precision and low cost to produce all micro-positioning features (such as the mounting part for fixing the conductor), enabling easy installation and precise and reliable fixing of the conductor. In a three-dimensional use state, the flexible features designed inside (such as the connecting bridge part) can release the structural shape potential of the structure itself, making it easy to flexibly and accurately transform into ring-shaped, arc-shaped, or curved structures according to the required shape of the conductive ring.

[0007] The technical solution adopted in this application is as follows: A conductive body fixing device includes a strip structure integrally formed from a flexible conductive strip, the strip structure comprising: Fixed belt main body: As the structural foundation and main load-bearing component of the entire device, it forms the main frame of the ring after being bent into a ring; Multiple connecting bridge sections are formed at intervals on the main body of the fixing belt. Their core concept is to act as pre-defined, controllable flexible components. By designing their geometry (such as width, length, and weakening structures), deformation can be actively concentrated and controlled in these areas, thereby preventing uncontrollable plastic deformation of the fixing belt main body and the mounting portion, ensuring the consistency and repeatability of the bending process. Mounting section: Located on the main body of the fixing band and at one end of the connecting bridge section. Its core concept is as a "precision mooring" for the conductors. These mounting sections are mass-produced with extremely high relative positional accuracy during the planar machining stage, ensuring that the relative spatial relationships between all conductors are precise and predictable after bending into a three-dimensional shape. The mounting section includes a receiving structure, the axis of which is arranged radially, axially, or tangentially relative to the plane of the fixing band main body.

[0008] After obtaining the above-mentioned strip structure, the strip structure can be flexibly bent to form the predetermined structure required for the conductive ring, such as a closed ring, an unclosed arc, or other three-dimensional structural forms, thereby realizing the leap from "two-dimensional precision" to "three-dimensional complexity".

[0009] Preferably, the receiving structure is a seamless, one-piece molded channel, and one or both ends of the channel are set as an inlet transition port. The inlet size of the inlet transition port is larger than the aperture of the receiving structure, and the connection between the inlet transition port and the receiving structure forms a smooth transition surface.

[0010] Preferably, the inlet transition port is a multi-stage transition structure, including at least two tapered segments with gradually changing diameters, wherein at least one tapered segment has a taper angle of 30°-60°.

[0011] Preferably, the inlet edge of the inlet transition port is provided with a rounded corner structure with a radius of 0.1mm-2.5mm; and / or, the depth of the inlet transition port is 0.2-1 times the aperture of the receiving structure.

[0012] Preferably, the mounting parts are arranged in a single row, two rows in parallel, or three or more rows in parallel on the fixing belt body. When the mounting parts are arranged in two or more rows in parallel, the receiving structure axes of each row of mounting parts are parallel to each other or the receiving structure axes of each row of mounting parts form a predetermined angle.

[0013] Preferably, the mounting portion is provided with an elastic deformation zone; And / or, the top shape of the mounting portion is set to be planar, arc-shaped, or pointed.

[0014] Preferably, the width of the connecting bridge portion is smaller than the width of the fixing strap body; And / or, the connecting bridge portion is provided with a structural weakening portion, the structural weakening portion including at least one of a thinning area, a cut or a perforation.

[0015] Preferably, the conductive strip structure further includes a mechanical positioning structure, which is integrally formed on one or both sides of the fixing strip body, wherein the mechanical positioning structure includes at least one of positioning holes, positioning hole array, positioning groove, buckle or protrusion.

[0016] Preferably, the mechanical positioning structure is connected to the fixing belt body through a weak connection part, the thickness of the weak connection part being 10%-70% of the thickness of the fixing belt body, or the weak connection part comprising a fragile bridge structure or a V-shaped notch structure.

[0017] Preferably, the mechanical positioning structure is provided with an identification mark, which includes at least one of color coding, numerical code or barcode.

[0018] Compared with the prior art, this application has one or more of the following significant advantages: On the one hand, the processing and production standard has shifted from "assembly after manufacturing" to "assembly upon forming": the most time-consuming precision positioning work has been transferred from three-dimensional space to two-dimensional plane, which greatly reduces the manufacturing difficulty and cost; Secondly, it endows the shape of the conductive ring with "programmability": by changing the flexible distribution and bending method of the connecting bridge, the same basic strip structure can be derived into circles, ellipses, polygons and even arbitrary curved surfaces, realizing a high degree of design freedom and product versatility. In three aspects, it provides an ideal carrier for automated production: the strip form is compatible with roll-to-roll production processes, and can even be further combined with mechanical positioning structures, so that the entire process of feeding, conductor assembly and bending can be fully automated, significantly improving efficiency and consistency. In four aspects, the overall performance of the product has been improved: the one-piece molding structure avoids assembly interfaces and has high reliability; the precise positioning of the conductors ensures the stability of electrical performance; and the flexible foundation adapts to a wider range of application scenarios.

[0026] Traditional conductive ring structures are basically based on a fixed-shape skeleton design, which causes many disadvantages in manufacturing. Moreover, when applying conductive skeletons to different conductive ring applications, it is difficult to quickly adapt to the needs of actual scenarios, which restricts the improvement of production efficiency and keeps production costs high.

[0027] To address the challenges in production and use, an in-depth analysis of the aforementioned pain points in the industry chain revealed that the root of the problem lies in treating "structural forming" and "conductor fixing" as two separate process steps.

[0028] Therefore, this application focuses on whether the two can be integrated in advance onto a basic component, and whether the problem can be fundamentally solved through an intermediate product with "shape preset capability" and "high-precision positioning capability".

[0029] Based on this, the concept of this application shifted to finding a solution that is integrally molded, flexible and deformable, and has its own precise positioning function. This breaks away from the mindset of the traditional fixed shape "skeleton" of conductive rings and turns to a new technical path such as "flexible strip substrate + deformable connecting bridge + precise mounting part".

[0030] The implementation of the technical concept of this application will be illustrated below with reference to the accompanying drawings and through multiple embodiments.

[0031] Example 1: Basic Structure and "Two-Dimensional to Three-Dimensional" Design and Manufacturing This embodiment demonstrates the most basic structural form and core working principle of this application.

[0032] To address the issues of rigidity, bulkiness, and complex manufacturing of traditional conductive ring structures, this application proposes a "planar prefabrication, spatial forming" production strategy. Specifically, a flexible conductive strip structure containing all functional elements is first fabricated on a two-dimensional plane. Then, during the final formation of the actual conductive ring structure, the strip structure's inherent flexibility allows for a flexible, rapid, and precise transformation into the actual three-dimensional conductive ring structure.

[0033] Reference Figures 1 to 16 In this embodiment, the conductive fixing device is made by precision stamping and integral forming of a flexible metal strip (such as a beryllium copper alloy with good elasticity and conductivity).

[0034] In practice, the conductive fixing device includes an integrally formed strip structure, which has the following parts: a fixing strip body 102, a connecting bridge part 103, and a mounting part 104.

[0035] The main body 102 of the fixing belt serves as a stable skeleton after shape transformation. In its planar state, it provides rigid support for easy processing and handling; after being bent into a three-dimensional shape (such as a ring shape), it becomes the main load-bearing structure of the ring. In practice, its width W1 and thickness T1 can be calculated and determined according to the mechanical strength requirements of the target ring.

[0036] Connecting bridge 103: Key to achieving "controlled bending". By designing its width (denoted as W2) to be much smaller than the width of the fixing belt body 102 (denoted as W1) (for example, setting W2 to 0.1-0.7 times W1), a series of pre-defined, spaced flexible connecting parts are artificially created. Therefore, when a bending moment is applied to the belt structure, deformation occurs preferentially and uniformly in these connecting bridges 103, rather than at random other locations.

[0037] The design of the connecting bridge 103 can achieve one or more of the following effects: (a) The bending process requires a small and stable force; (b) The formed ring structure has good roundness and high shape consistency; (c) The position of the mounting part 104 will not shift due to uncontrollable deformation.

[0038] Mounting part 104: Its core is to reduce the precise positioning problem in three-dimensional space to a two-dimensional plane. When stamping this strip structure, the positions of all mounting parts 104 relative to the fixed strip body 102 are formed simultaneously in the same process and under the same reference. This means that the relative positions between these mounting parts 104 can have extremely high precision, and this precision depends only on the precision of the mold (e.g., up to the micrometer level), which is far higher than the precision of assembling individual parts onto a three-dimensional skeleton (basically several millimeters or more).

[0039] Furthermore, when forming the required shape of the conductive ring, the strip structure is bent along its length. Due to the flexible hinge action of the connecting bridge 103, each segment of the fixed strip body 102 rotates around a virtual center, eventually connecting end to end to form a stable ring structure. At this time, the mounting part 104, "suspended" by the connecting bridge 103, is precisely "placed" at a predetermined position on the circumference. A conductor (such as a bundle of conductive fibers) can pass through each mounting part 104 in sequence, thereby being precisely fixed on an ideal circular path. The entire process achieves a seamless transformation from a "high-precision planar matrix" to a "high-precision three-dimensional structure".

[0040] Example 2: Mounting section housing structure and its "non-destructive guidance and stable clamping" This embodiment focuses on how the mounting part 104 specifically achieves the fixation of the conductor. Its concept originates from solving the problems of damage risk and fixation reliability of conductors (especially thin-diameter or fragile fiber bundles, wires, etc.) during the assembly process.

[0041] To address the challenges of quickly and non-destructively introducing conductors into a confined installation space, and to ensure their secure fixation under harsh conditions such as vibration and temperature changes, this application provides an integrated "guiding-accommodating-clamping" functional design for the installation space.

[0042] refer to Figure 4 As shown, this application designs some preferred structures on the mounting section 104.

[0043] For example, seamless one-piece molded channel 105 (i.e., receiving structure): Considering that there may be burrs or seams at the opening in the conventional solution, which may easily scratch the wire, this application adopts a seamless hole design based on the above concept of one-piece molding design and production, which eliminates this risk from the root. For example, by designing precision pins on the mold, a channel with a smooth inner wall is formed synchronously with the strip stamping, which protects the conductor and ensures the uniform distribution of clamping force.

[0044] For example, the transition port 106 is a key design element that directly embodies the concept of "non-destructive guidance." Its core idea is to use geometric transitions to gradually guide and converge macroscopic assembly actions, which may contain deviations, to microscopic, precise alignment. Preferably, a smooth transition can be provided. It should be noted that transition ports 106 can be provided at both ends of the channel 105.

[0045] For example, smooth transition surfaces: see Figure 4 The schematic cross-sectional view shows that the inlet transition port 106 is set as a curved surface, which can disperse the inlet force and avoid stress concentration during the guiding process.

[0046] For example, a multi-stage transition structure: A multi-stage structure is used to create a better transition entry structure. For instance, the first-stage conical segment (45°-60° taper angle) is responsible for wide-range correction and initial guidance, capturing even if the robot-held wire has a large positional deviation; the second-stage conical segment (30°-45° taper angle) is responsible for fine alignment, further calibrating the wire to coincide with the axis of the receiving structure (i.e., channel 105). This two-stage guidance mechanism, "coarse first, fine later," is particularly suitable for high-speed automated assembly, significantly reducing the requirements for docking accuracy and improving the assembly success rate.

[0047] For example, structural designs such as rounded corners (e.g., corner radius of 0.1mm-2.5mm) and low roughness (Ra≤0.8μm) better achieve the "non-destructive" guidance installation requirements, remove possible microscopic sharp edges, reduce guidance damage, and improve product reliability.

[0048] For example, the elastic deformation zone enables "easy installation and fixation" and "stable clamping," improving the reliability of conductor fixation. For example, based on the elastic deformation zone, it is no longer necessary to rely on specific external measures, such as glue or clips, but to utilize the material elasticity of the mounting part 104 itself to generate active clamping force.

[0049] In practice, by designing slots or locally thinning the sidewalls of the mounting portion 104, a region capable of elastic deformation under stress is created. When the conductor is pressed in, this region can be elastically expanded, and the internal stress of the material continuously applies a radial clamping force to the conductor, forming a reliable frictional fixation. This dynamic elastic clamping is more adaptable to temperature changes and minor vibrations than a static interference fit. Alternatively, the mounting portion 104 can be designed as a structure with elastic deformation capabilities, allowing the tooling to deform the mounting portion 104 and clamp the conductor. For example, the tooling can press the mounting portion 104, causing deformation of the internal housing structure to clamp the conductor.

[0050] During implementation, different optimization designs can be made for the shape of the mounting part 104, for example... Figures 5 to 7 The illustration shows that the top of the mounting part 104 has a triangular-like top structure in its vertical cross-section, and Figures 8 to 9 The illustration shows that the top of the mounting part 104 has a semi-circular top structure in the vertical section.

[0051] Example 3: Installation unit arranged in multiple rows, ensuring "spatial wiring density and flexibility" The aforementioned example illustrates a design using a single-row mounting section, where each mounting section secures only a single conductor. In applications requiring special electrical signal transmission connections, such as differential pair conductor fixing designs or multi-phase electrical signal connections, achieving compact, multi-channel cabling in three-dimensional space without significantly increasing structural complexity becomes particularly important.

[0052] Therefore, this example uses multiple rows of conductive fixing parts arranged in the mounting section.

[0053] refer to Figures 17 to 18 This embodiment illustrates that the core concept is to pre-define the wiring relationships in three-dimensional space on a two-dimensional plane: by designing the mounting parts 104 to be arranged in multiple parallel rows (e.g.) Figure 17 It is a double row. Figure 18 (For three rows), thus, before bending and forming, the arrangement path of conductors at different radii or axial positions on the future three-dimensional ring has been defined on the plane.

[0054] It should be noted that the ingenuity of this example lies in its utilization of the high precision advantages of planar machining to solve the problem of winding multi-layer coils in three-dimensional space in a single operation. For example, for Figure 17 The double-row design allows for the simultaneous forming of two rows of mounting parts in the stamping die, ensuring that the concentricity and spacing accuracy between the two rows are far superior to those achieved by manual winding or step-by-step assembly.

[0055] This application also provides some preferred structural designs for the arrangement of conductors.

[0056] For example, the axial orientation configuration further expands the flexibility of wiring. For instance, when the axes of the two rows of mounting structures are parallel (e.g., both radially oriented), two concentric conductors are fixed. Alternatively, when the two rows of axes form a predetermined angle (e.g., one radial and one axial), electrical connections facing both the center and the outer edge can be simultaneously achieved on a ring structure, meeting more complex interface requirements. Therefore, the ability to pre-determine spatial orientation at the planar stage is a unique advantage of this application, enabling the product to better adapt to various specific applications of the conductive ring.

[0057] Example 4: Weakening of Connecting Bridge Structure and "Precise Control of Bending Performance" Reducing the width of the connecting bridge section can improve flexibility to a certain extent, but this application has made relevant improvements on how to more accurately control the bending moment, bending radius and fatigue life, as well as how to avoid the concentration of bending stress at the root of the connection between the bridge section and the main body.

[0058] The core concept of this embodiment is to perform some structural optimization designs to "fine-tune the performance" of flexible hinges.

[0059] For example, by introducing a structural weakening part 107 (such as reference 107) Figure 5 , Figure 7 (as illustrated), a "preset weak point" is actively created on the connecting bridge 103 to precisely control the bending behavior.

[0060] For example, thinning of the region: by reducing the thickness of a specific region through methods such as local etching or fine pressing, the bending stiffness can be significantly reduced without changing the external profile, thus achieving a smaller bending radius.

[0061] For example, notches or perforations: By incorporating structural optimization designs such as notches and perforations, not only is stiffness reduced, but more importantly, stress is redistributed. For instance, a V-shaped notch allows bending stress to be distributed more evenly across the entire depth of the notch, rather than concentrating at the root, thereby significantly improving fatigue resistance and extending the product's service life under repeated bending conditions.

[0062] Therefore, by achieving "designable flexibility" through the above examples, this application can flexibly adapt to various application scenarios, from one-time bending and forming (such as fixed conductive ring circular applications) to repeated bending (such as special occasions where the conductive ring needs to follow the component to continuously change shape to achieve dynamic sliding contact).

[0063] Example 5: Mechanical positioning structure and its application in facilitating fully automated production. For semi-finished piles, how to ensure that the strip structure is accurately positioned throughout a series of automated processes such as roll packaging, conveying, conductor assembly and bending forming? The core concept of this embodiment is to introduce a "process reference structure" that is integrally formed with the functional structure but can be separated in the final product. That is, by adding a small amount of structural design, automated production and manufacturing can be optimized, providing strong support for enterprises to reduce costs and increase efficiency.

[0064] The core concept of this embodiment is to add a portion of intermediate product structure design to the main body of the fixed belt.

[0065] For example, mechanical positioning structure 111 (reference) Figures 15 to 16 As shown in the diagram, the structure also includes some positioning holes 112: these structures are formed in the same process as the functional parts (installation part, fixing belt body), so their relative positions are precise and known. Thus, this structural information can be used in automated equipment. For example, positioning pins can be inserted into these positioning structures to achieve precise positioning and correction of the belt at each station, which is conducive to achieving high-precision automated assembly.

[0066] For example, a weak connection 113 is provided between the positioning structure and the main body of the fixing belt (see reference). Figures 15 to 16 (The dashed box portion is shown in the diagram), and the weak connection portion 113 is designed to be cut off: the designed positioning structure becomes redundant "excess" after the process reference is completed. Therefore, it is connected to the main body through the weak connection portion 113 (the thickness of which is only 10%-70% of the thickness of the main body).

[0067] It should be noted that the design of adding a weak connection part 113 can achieve the separation of "function and process": for example, it provides strong support for positioning and connection during the assembly process, and after the assembly is completed, the positioning structure can be cleanly broken and separated from the weak connection part by a simple punching or bending action, thereby achieving the lightweight and miniaturization of the final product.

[0068] For example, identification markings: By using identification markings (such as shapes and patterns forming specific identifiers), "physical benchmarks" and "information benchmarks" can be integrated, increasing the convenience and precision of manufacturing. For example, barcodes or numerical codes can be used for positioning and traceability on the production line, effectively preventing improper assembly, material mixing, etc., and enabling flexible production.

[0069] Example 6: A strip structure with "shape configurability" In the exploration of technical improvements before the upgrade, it was found that traditional conductive rings were almost equivalent to "circular rings". However, in modern electronic devices, due to the ever-changing installation space and different electrical performance requirements, for example, a circular ring may not be able to effectively fill a rectangular corner.

[0070] Therefore, there is an urgent need to provide a new solution that breaks the mindset that "conductive rings must be circular," so that the shape of conductive structures can be flexibly adapted to various physical spaces like "building blocks."

[0071] As illustrated in the examples above, the core concept of this application lies in shifting the determining factor of shape from the "mold" to the "bending operation." By designing a long, flexible strip structure that does not inherently possess a specific shape, a "blank check" is created for subsequent shaping. Its final form can be flexibly bent into a specified shape profile after being "filled" in during the final stage of assembly according to the actual requirements of the conductive ring.

[0072] For example, an elliptical configuration: the strip structure is bent into an elliptical loop. The key is that the flexible design of the connecting bridge 103 can adapt to continuously changing radii of curvature. Near the major axis endpoint of the ellipse, the radius of curvature is small, and the deformation of the connecting bridge 103 is large; near the minor axis endpoint, the radius of curvature is large, and the deformation is small. Therefore, the entire strip structure smoothly conforms to the elliptical trajectory through the adaptive deformation of the connecting bridge, allowing a single, standardized strip product to be applied to specific non-circular devices.

[0073] For example, polygonal configurations (such as regular hexagonal rings): When a conductive ring needs to be embedded in the right-angle corners of a honeycomb structure or a regular modular device, a circular ring would result in a significant waste of space. This application addresses this by bending a strip structure into a regular hexagonal ring. The essence of this concept lies in controlling the bending operation, using the connecting bridge 103, originally designed for smooth bending, as a "discrete hinge." At each corner of the polygon, one or more connecting bridges 103 undergo concentrated bending, while the straight edges of the polygon are formed by rigid segments that fix the main body 102. This alternating "hinge-rigid segment" structure perfectly realizes the polygonal profile. It greatly improves space utilization and provides modular possibilities for product design.

[0074] For example, a fan-shaped / semi-circular configuration: In some sensor or communication applications, only a directional non-full-ring structure may be needed, because a full-ring structure not only wastes materials but may also cause unnecessary interference. This application only needs to bend the strip structure to the required angle (such as 180° to form a semi-circle, or 90° to form a fan shape, etc.) and keep it in a non-closed arc shape.

[0075] It should be noted that this concept breaks the traditional understanding that conductive rings must be closed loops. Its technical value lies in realizing the "on-demand customization" of functions, eliminating redundant parts, reducing costs, weight and power consumption, while avoiding the problems that may be caused by a full loop (such as installation interference, excessive space occupation, etc.).

[0076] For example, linear, polygonal, and wavy configurations: This application breaks with traditional thinking, namely whether the basic structure can only be used for ring applications and whether it can be extended to one-dimensional or two-dimensional planar wiring scenarios, thus providing new layout scenarios.

[0077] For example, in a straight line, if the strip structure is kept straight, it becomes a high-precision linear conductor fixing and positioning fixture, which can be used to fix and install multiple parallel conductive lines, ensuring that their spacing and position are absolutely accurate, such as for manufacturing highly consistent differential signal harnesses.

[0078] For example, in the zigzag type, the strip structure is bent at a specific angle at multiple points to form a sawtooth or stair-shaped path, which can be applied to circuits that require specific electrical lengths or impedance matching.

[0079] For example, in wave-shaped structures, the strip structure is continuously bent to form curved shapes such as sine waves. By elevating it to a kind of "conductive trajectory template", it is possible to achieve complex two-dimensional planar wiring that cannot be easily accomplished by traditional winding.

[0080] Example 7: Material Selection for Strip Structures Different application scenarios place vastly different requirements on conductive fixing devices. For example, some require extremely high conductivity, some require excellent fatigue life, some require corrosion resistance, and some require integration with insulating substrates.

[0081] The advantage of this application is that its structural design is decoupled from the material selection. The topology of "flexible strip matrix + connecting bridge + mounting part" has strong material universality. Therefore, the most suitable strip material can be selected in reverse according to the design requirements of the final product without changing the basic structural design.

[0082] For example, metal strips (such as copper strips): these materials are chosen to maximize the combination of mechanical properties and electrical conductivity. For instance, beryllium copper has extremely high yield strength and excellent fatigue life, ensuring that the connecting bridge 103 is not prone to plastic deformation or fracture after repeated bending, making it particularly suitable for moving parts (such as slip rings). At the same time, its good electrical conductivity ensures that its resistance is sufficiently low if the fixing strip body 102 needs to be part of a current path. For example, phosphor bronze offers better elasticity and cost advantages, making it ideal for utilizing the elastic deformation zone of the mounting part 104 to clamp wires.

[0083] For example, conductive composite materials (such as silicone or epoxy resin-based tapes filled with silver powder): These materials are chosen to address the issue of excessive rigidity in metal materials, which is problematic in applications requiring high flexibility, significant stretchability, or conformability to soft substrates. Because these materials possess inherent elasticity and stretchability, not only can the connecting bridge 103 bend, but the entire fixing tape body 102 also exhibits a degree of elasticity, allowing the entire device to be applied to dynamic curved surfaces such as wearable devices and flexible robots. Although the electrical conductivity is slightly lower than that of metals, it still meets the basic electrical performance requirements for signal transmission.

[0084] For example, flexible printed circuit board (FPC) materials (such as copper-clad polyimide): Through flexible circuit boards, "passive fixing" can be upgraded to "active integration," transforming the strip structure from a mere mechanical fastener into a functional component with its own circuitry. For instance, by using FPC material as the substrate for the strip structure, and based on etching processes, not only can the outlines of the connecting bridge 103 and the mounting portion 104 be formed, but pre-defined circuit traces can also be etched onto the fixing strip body 102. These traces can be directly connected to additional conductors (such as coil wires) mounted on the mounting portion 104, forming a complex circuit network. This eliminates the need for additional soldering and assembly steps, significantly improving system integration and reliability.

[0085] Example 8: Example of "one-piece molding" forming a strip structure This application selects manufacturing processes that ensure both precision and efficiency while taking into account the characteristics and costs of different materials, thus enabling compatibility with various processes from traditional subtractive manufacturing to modern additive manufacturing.

[0086] For example, stamping: using high-precision, high-efficiency dies for large-scale replication is the preferred method for metal strip and mass production. By designing and manufacturing a set of precision progressive dies, punching, blanking and other processes are continuously performed on the metal coil to form the entire strip structure in one go, including the tiny inlet transition and structural weakening parts. The manufacturing process has extremely high production efficiency and low unit cost, making it very suitable for mass production.

[0087] For example, etching (photochemical processing): When the structural features are extremely fine (such as connecting bridges with a precision of less than 0.1 mm), a stress-free "etching" molding method can be used. For instance, by coating a strip with photoresist, exposing and developing it, and then using chemical solvents to etch away the unprotected areas, the desired shape is formed. This process can produce ultra-fine structures without burrs or mechanical stress, making it particularly suitable for applications requiring extremely high precision and surface quality, such as medical micro-devices and high-frequency FPC components.

[0088] For example, 3D printing (additive manufacturing): 3D printing enables the integrated manufacturing of complex three-dimensional structures that are impossible to achieve with traditional processes. For instance, using a 3D printer capable of printing conductive materials (such as conductive polymer composites or nano-silver paste), the strip structure described in this application can be directly manufactured layer by layer, easily accommodating changes in the structural axis in any direction in space, or creating mounting parts with irregular shapes. This is a preferred and feasible manufacturing solution for small-batch production, prototyping, or products with extremely complex structures.

[0089] For example, die-cutting: using lower-cost cutting tools for shaping. By using custom dies, materials are separated through pressure cutting, resulting in a highly efficient manufacturing process with costs between stamping and etching. This is a feasible solution for processing conductive composite materials or simple FPC structures.

[0090] Example 9: A variation of "integrated molding" from "integration of homogeneous materials" to "integrated composite of heterogeneous materials". A single material often cannot meet all the requirements. Metal areas that require high strength and high conductivity may be too rigid, which is not conducive to use in areas where large deformation is required. On the other hand, using flexible composite materials as a whole may sacrifice the rigidity and conductivity of the structure.

[0091] Therefore, if the advantages of different materials are integrated into a single strip structure to achieve a combination of rigidity and flexibility as well as functional partitioning of conductivity and insulation, a completely new structural design can be provided for conductive rings.

[0092] The concept behind this application is to extend "integrated molding" from "integration of homogeneous materials" to "integrated composite of heterogeneous materials." Furthermore, through advanced manufacturing processes, the most suitable materials can be used in different regions.

[0093] For example, the strip structure is made of a multi-material composite base strip. For instance, the main body of the fixing strip 102 and the mounting part 104 are made of high-strength metal materials (such as stainless steel or hard copper alloy) to ensure the stability and reliability of the overall structure.

[0094] The connecting bridge 103 is made of highly elastic conductive composite material or superelastic metal (such as nickel-titanium). These two materials are combined at the microscopic level through advanced processes such as overmolding, solid-state welding or laser cladding to form a truly inseparable integrated component.

[0095] Furthermore, a layer 207 of a precious metal material such as silver or gold with high conductivity and low contact resistance can be coated on the inner wall of the housing structure of the mounting part 104 by electroplating or vapor deposition, while the mounting part body uses a lower-cost conductive substrate.

[0096] The fixed belt body 102 provides structural rigidity, ensuring the stability of the final form. The connecting bridge 103, due to its special composite material, possesses bending fatigue life and deformation capacity far exceeding that of ordinary metals, allowing the entire device to withstand millions of repeated bends. The precious metal layer on the inner wall of the mounting section 104 is specifically designed to provide an excellent electrical contact interface, reducing contact resistance. Therefore, through this composite structural design, functions such as "structural support," "flexible connection," and "excellent electrical contact" are simultaneously achieved. Each function is undertaken by the most suitable material in the most suitable position, breaking through the performance limits of a single material and achieving a leapfrog improvement in the overall performance of the product. Furthermore, it specifically addresses the fatigue life issue in the flexible hinge area, greatly extending the product's service life in dynamic application scenarios. Additionally, while ensuring key electrical performance, the overall cost is optimized (precious metals are used only in critical electrical contact areas).
