Description

Technical Field

[0001] This invention relates to the field of electrical connector technology, and more specifically to a flat braided wire piercing conductive connector clip. Background Technology

[0002] Currently, conventional flat braided wire conductive connection methods mostly require stripping and tinning the ends of the wires in advance, and then completing the conductive connection with the PCB board by soldering or crimping terminals. The whole process is cumbersome, with low production efficiency and high labor costs.

[0003] Most existing piercing connection structures can only be used with conventional round wires or ordinary flat cables, and cannot be used with special flat braided wires with two independent conductive wires embedded inside. They generally suffer from unstable piercing contact and the conductive wires are prone to displacement and detachment. At the same time, most similar products on the market adopt a split assembly structure, which requires multiple steps to complete the wire fixing, conductive sheet installation, PCB soldering and other processes. The overall structure has poor compactness, and the alignment accuracy of the PCB socket on the back is difficult to guarantee. After long-term use, defects such as poor contact and signal transmission interruption are likely to occur. Summary of the Invention

[0004] Therefore, it is necessary to address the problems of complex connection processes, low assembly accuracy, poor contact stability, and insufficient reliability of existing flat braided wires by proposing a flat braided wire puncture-type conductive connection buckle to achieve rapid assembly and stable conductive connection between the wire and the PCB board without stripping and pressing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A flat braided wire piercing conductive connector buckle includes: An insulating housing includes an upper cover and a lower cover, the upper cover and the lower cover are hinged together, and the interior is provided with a receiving groove for placing flat braided wire. The upper cover is provided with a snap-fit ​​structure that can be pressed down, and the lower cover is provided with a clearance through hole. The snap-fit ​​structure can be engaged with or opened with the clearance through hole, and a flexible gasket is provided at the bottom of the receiving groove. Two beryllium copper piercing conductive sheets are fixed inside the insulating shell. Each beryllium copper piercing conductive sheet has a piercing edge at the upper end and a pin structure for welding at the lower end. The pin structure is set to pass through and avoid through holes. A miniature PCB board with an integrated 2P female socket is fixed to the back of the insulating shell. The miniature PCB board has two circular holes that correspond one-to-one with the pins of the beryllium copper piercing conductive sheet. The 2P female socket is soldered and fixed to the surface of the miniature PCB board, and the pins of the 2P female socket are connected to the internal wiring of the miniature PCB board.

[0007] In some embodiments, the cutting edge angle is 53°.

[0008] In some embodiments, the receiving groove of the insulating shell is provided with a limiting groove that aligns with the two conductive wires inside the flat braided wire.

[0009] In some embodiments, the micro PCB board is detachably fixed to the insulating shell by a pre-positioning snap-fit ​​structure, and the circular hole of the micro PCB board is aligned and matched with the pin of the beryllium copper piercing conductive sheet.

[0010] In some embodiments, the pin structure is a flat, straight-through structure, and the outer contour of the pin is adapted to the inner contour of the circular hole on the micro PCB board.

[0011] In some embodiments, the receiving groove is a long, flat groove structure adapted to the shape of a flat braided yarn, and the width of the groove is matched with the width of the flat braided yarn.

[0012] In some embodiments, the snap-fit ​​structure is provided with a self-locking engagement portion.

[0013] In some embodiments, the beryllium copper piercing conductive sheet has a gold-plated layer on its surface.

[0014] In some embodiments, the insulating shell is made of high-temperature resistant and flame-retardant plastic material.

[0015] This invention utilizes a hinged top and bottom cover, an internal receiving groove and flexible gasket, a beryllium copper piercing conductive sheet, and a micro PCB board on the back to achieve bonding and conductivity without stripping or tinning the flat braided wire. Assembly is simple and efficient. The snap-fit ​​structure allows for opening and locking, and the piercing edge penetrates the insulation layer to reliably contact the conductive wire. The pins are soldered to the PCB board's circular holes to form a complete conductive circuit. The structure is compact, preventing wire damage under pressure, ensuring a stable and secure connection, reducing assembly costs, and making it suitable for rapid conversion of flat wire harnesses in various electronic devices.

[0020] To address the problems of cumbersome flat braided wire connection processes, the need for wire stripping and tinning, poor assembly precision, unstable conductive contact, and long-term easy loosening and failure in existing technologies, the following will combine the attached... Figures 1 to 4 This invention provides a flat braided wire piercing conductive connection buckle, which achieves fast assembly of flat braided wires without stripping, high precision, high stability, and long-term reliable conductive signal connection through an integrated buckle structure, a 53° three-edge piercing structure, wire limiting positioning, and PCB pre-positioning self-locking structure.

[0021] Please see Figures 1 to 4 , Figure 1 This is a schematic diagram of the overall structure of the flat braided wire piercing conductive connection buckle according to an embodiment of the present invention; Figure 2 This is an exploded view of the assembly of the flat braided wire piercing conductive connector buckle according to an embodiment of the present invention; Figure 3 This is a schematic diagram of the open state of the flat braided wire piercing conductive connection buckle according to an embodiment of the present invention; Figure 4 This is a schematic diagram of the three-dimensional structure of beryllium copper piercing the conductive sheet according to an embodiment of the present invention.

[0022] A flat braided wire piercing conductive connector buckle includes: The insulating housing 1 includes an upper cover 11 and a lower cover 12, the upper cover 11 and the lower cover 12 are hinged together, and the interior is provided with a receiving groove 11 for placing flat braided wire. The upper cover 11 is provided with a snap-fit ​​structure 111 that can be pressed down, and the lower cover 12 is provided with a clearance through hole 121. The snap-fit ​​structure 111 can be engaged with or opened with the clearance through hole 121. A flexible gasket 112 is provided at the bottom of the receiving groove 11. Two beryllium copper piercing conductive sheets 2 are fixed inside the insulating shell 1. Each beryllium copper piercing conductive sheet 2 has a piercing blade 21 at the upper end and a pin structure 22 for welding at the lower end. The pin structure 22 is set to correspond to the through-hole 121. The miniature PCB board 3 with integrated 2P female socket is fixed to the back of the insulating shell 1. The miniature PCB board 3 has two round holes 31 that correspond one-to-one with the pins of the beryllium copper piercing conductive sheet 2. The 2P female socket is soldered and fixed to the surface of the miniature PCB board 3. The pins of the 2P female socket are connected to the internal wiring of the miniature PCB board 3.

[0023] Specifically, this device adopts an integrated snap-fit ​​structure, abandoning the traditional modular design of electrical connectors. It is assembled from three core components: an insulating shell 1, two independent beryllium copper piercing conductive plates 2, and a miniature PCB board 3 integrating a 2P female socket. There are no unnecessary auxiliary assembly parts, resulting in a highly integrated and compact structure. The insulating shell 1 serves as the overall load-bearing base, with an internal elongated receiving groove 11 serving as a dedicated placement station for flat braided wires. A flexible pad 112, preferably a silicone pad, is placed at the bottom of the receiving groove 11 for cushioning and protection. A snap-fit ​​structure 111 that can be pressed vertically downwards is integrated above the receiving groove 11. Two symmetrical clearance holes 121 are formed at the bottom of the receiving groove 11, with the hole diameter matching the pin size of the beryllium copper piercing conductive plate 2. Two beryllium copper piercing conductive plates 2 are fixedly embedded in the pre-set installation positions inside the insulating shell 1. The positions are parallel to each other and insulated from each other. Each beryllium copper piercing conductive plate 2 has a piercing blade 21 extending from the upper end and an integrally formed welded pin at the lower end. The pin vertically penetrates the bottom avoidance through hole 121 to achieve structural positioning. The miniature PCB board 3 is fixed to the back of the insulating shell 1 by a snap-fit ​​pre-installation structure. The surface of the PCB board has two pre-set alignment circular holes 31. The position and spacing of the circular holes 31 correspond one-to-one with the pins of the two beryllium copper piercing conductive plates 2. A standard 2P female socket is welded to the surface of the PCB board. The internal pins of the female socket are connected to the copper foil traces built into the PCB board to form a complete signal conduction circuit.

[0024] Working principle: During assembly, there is no need for pre-processing such as stripping, tinning, and crimping terminals on the flat braided wire. The complete double-layer insulated flat braided wire is directly laid flat inside the receiving groove 11 of the insulating shell 1, ensuring that the wire is placed flat and without twisting or offset. The snap-fit ​​structure 111 is pressed down at a uniform speed by manual operation or equipment. With the downward stroke of the snap-fit ​​structure, the beryllium copper piercing conductive sheet 2 fixed inside the insulating shell 1 is displaced relative to the wire. Through the piercing action of the cutting edge, it penetrates the outer braided insulation layer of the flat braided wire, so that the conductive sheet contacts the two independent conductive wires inside the wire. At the same time, the lower end of the conductive sheet is firmly inserted into the round hole 31 of the micro PCB board 3. After being fixed by welding, the flat braided wire, beryllium copper conductive sheet, micro PCB board 3, and 2P female socket are fully conductive, completing the rapid assembly connection.

[0025] Beneficial effects: Compared to traditional flat braided wire welding and crimping connections, this method eliminates multiple cumbersome processes such as wire stripping, tinning, and terminal crimping, simplifying the assembly process. It requires no specialized welding equipment or skilled workers, improving wire harness processing efficiency and significantly reducing labor and equipment production costs. Furthermore, it abandons the multi-part assembly structure of traditional split connectors, featuring an integrated design that is compact and small in size, suitable for the limited installation space inside miniaturized electronic devices. This addresses the fundamental structural issues of poor alignment accuracy, loose assembly, and long-term loosening associated with traditional split structures, providing a fundamental structural guarantee for fast and stable electrical connections with flat braided wires.

[0026] In one embodiment, the beryllium copper piercing conductive sheet 2 adopts an integral stamping structure, and the piercing blade 21 is a three-blade structure with side-by-side blades and acute angles.

[0027] Specifically, the beryllium copper piercing conductive sheet 2 is made of a highly elastic and highly conductive beryllium copper alloy, formed in one piece through an integral stamping process, without secondary welding, bending, or splicing. The overall structure has no splicing gaps and uniform structural strength, avoiding the defects of easily deformed, broken, and loosely connected conductive sheets caused by split molding. Three sets of piercing blades 21 are integrally formed and arranged side-by-side at the upper end of the conductive sheet. The three sets of blades are evenly distributed along the width of the flat braided wire, and the blades adopt an acute-angle structure design with uniform thickness, smooth surface, and no burrs, ensuring smooth piercing. The three blades are at the same height and bear force synchronously, acting simultaneously on the surface of the insulation layer of the flat braided wire during the downward pressure process. This multi-point synchronous piercing, compared to single-blade or double-blade structures, results in more uniform piercing force, avoiding the problems of wire compression deformation and excessive local tearing of the insulation layer caused by single-point stress concentration. Meanwhile, the integrated stamping process can control the flatness and coaxiality of the cutting edge, ensuring that the piercing depth of each set of cutting edges is consistent, effectively adapting to the structural characteristics of the thin insulation layer of the flat braided wire and the built-in fine conductive wire.

[0028] Working principle: When the snap-fit ​​structure 111 is pressed down, three sets of parallel acute-angled cutting edges simultaneously contact the braided insulation layer of the flat braided wire. Utilizing the high-strength piercing performance of the acute-angled cutting edges, the warp and weft braided structure of the braided insulation layer is evenly broken, overcoming the bottleneck of traditional ordinary cutting edges being unable to pierce dense braided insulation layers. The three cutting edges simultaneously contact the conductive wires inside the wire, forming a multi-point contact conductive structure, increasing the conductive contact area. At the same time, the integrally molded conductive sheet structure ensures that it will not deform during the piercing process, always maintaining the fit between the cutting edge and the conductive wire, avoiding problems such as incomplete contact or contact misalignment in a single contact.

[0029] Beneficial effects: The integrated stamping process ensures the overall structural strength and dimensional accuracy of the conductive sheet, eliminating the defects of spliced ​​conductive sheets such as loosening, deformation, and poor contact. The three-edged acute-angle structure is suitable for piercing the dense braided insulation layer of flat braided wires, easily breaking through the layer without strong pressure and without compressing or damaging the wire itself. Multi-point contact conduction increases the conductive contact area, reduces contact resistance, and improves the stability of signal transmission. It effectively solves the technical problems of existing piercing structures such as single-edged contact, small contact area, easy to have poor connection, and unstable signal transmission. At the same time, the structural forming process is simple and suitable for mass production.

[0030] In one embodiment, the cutting edge angle is 53°.

[0031] Specifically, this angle is the optimal puncture angle obtained through multiple tests and optimizations, differing from the conventional 45° and 60° puncture angles. The 53° blade angle balances puncture sharpness and structural strength, ensuring a sharp blade tip and sufficient support strength. It avoids the problem of an excessively thin blade that is prone to chipping and deformation under pressure due to an excessively small angle, while also preventing excessive puncture resistance that would hinder penetration of the densely braided insulation layer. In this embodiment, the three sets of blade angles are uniform, with an error controlled within ±1°, ensuring high angle consistency. This guarantees complete synchronization of puncture force and depth across the three sets of blades, adapting to the special flat braided wire structure with built-in dual independent conductive wires.

[0032] Working principle: During the downward piercing process, the 53° acute-angle cutting edge can cut into the gaps in the braided insulation layer of the flat braided wire, orderly separating the braided fibers rather than violently cutting them. While completely penetrating the insulation layer and adhering to the internal conductive wires, the mechanical properties of the cutting edge angle avoid the problem of the tip directly cutting the conductive wires. This angle design allows for control of the piercing depth, ensuring that the cutting edge only penetrates the outer insulation braid layer and just contacts the surface of the internal conductive wires, without cutting into or severing the internal copper wires. This perfectly suits the connection requirements of fine flat braided wires.

[0033] Beneficial effects: The optimal 53° cutting edge angle solves two major pain points of traditional piercing structures: small-angle cutting edges are easily damaged, and large-angle cutting edges are difficult to pierce and easily break the conductive wire. At this angle, the cutting edge provides moderate piercing resistance and high structural strength. Long-term repeated pressing and piercing is not prone to wear and chipping, thus extending service life. At the same time, it can achieve the piercing effect of "breaking the insulation layer without damaging the conductive wire", avoiding problems such as open circuits and poor contact caused by broken or damaged conductive wires. This greatly improves the product assembly yield and long-term reliability, making it the optimal angle design for dual-wire flat braided wires.

[0034] In one embodiment, the receiving groove 11 of the insulating shell 1 is provided with a limiting groove that aligns with the two conductive wires inside the flat braided wire.

[0035] Specifically, inside the receiving groove 11 of the insulating shell 1, two sets of symmetrically arranged limiting grooves are integrally formed. The spacing and position of the two sets of limiting grooves correspond to the spacing of the two independent conductive wires inside the flat braided wire, and the width of the groove matches the wiring width of a single conductive wire. The limiting grooves are embedded groove structures, symmetrically distributed on both sides of the center of the receiving groove 11. During assembly, they can provide lateral limiting and radial positioning for the flat braided wire, restricting the wire's lateral displacement and forward and backward movement inside the groove. At the same time, the physical isolation structure of the grooves separates the two independent conductive wires, achieving physical insulation isolation between the two conductive wires. The grooves adopt an arc transition design, which will not scratch the outer insulating braided layer of the wire and protect the integrity of the wire.

[0036] Working principle: When the flat braided wire is placed inside the receiving groove 11, the area of ​​the wire corresponding to the conductive wire is engaged in the limiting groove. The limiting constraint of the groove fixes the placement and posture of the wire, preventing lateral slippage and misalignment caused by the pressure of the cutting edge during the pressing process. At the same time, the isolation structure of the two sets of grooves ensures that the two conductive wires always maintain a fixed distance, preventing the conductive wires from approaching, overlapping, or crossing. Structurally, this ensures the insulation performance between the two wires, eliminates the risk of short circuits, and, together with the piercing cutting edge 21, achieves independent conduction of the two wires.

[0037] Beneficial effects: This design overcomes the shortcomings of existing piercing structures, such as the lack of positioning and limiting mechanisms, easy displacement of flat braided wires under pressure, misalignment of conductive wires, and easy overlap and short circuits in double wires. By using positioning and limiting slots, the wires and conductive wires are positioned, ensuring consistent alignment in each assembly and significantly reducing poor contact and short circuits caused by assembly deviations. Furthermore, the physical isolation structure requires no additional insulating materials, is simple in design, highly stable, and will not experience insulation failure over long-term use, making it suitable for high-precision, high-stability signal transmission scenarios.

[0038] In one embodiment, the micro PCB board 3 is detachably fixed to the insulating shell 1 by a pre-positioning snap-fit ​​structure, and the round hole 31 of the micro PCB board 3 is aligned and matched with the pin of the beryllium copper piercing conductive sheet 2.

[0039] Specifically, the insulating shell 1 features a single-piece molded back with multiple pre-positioning clips made of elastic plastic, symmetrically arranged on both sides of the shell's back. Corresponding clip slots are provided on the micro-PCB board 3, forming a detachable and secure clip structure. The circular holes 31 on the micro-PCB board 3 align with the pins of the beryllium copper piercing conductive sheet 2. During assembly, no additional tooling or fixtures are required for positioning; the PCB board can be quickly snapped into place directly through the pre-positioning clips. Once engaged, the PCB board is secured, while also being detachable for easy future maintenance and replacement of the PCB board and female socket components.

[0040] Working principle: When assembling the miniature PCB board 3, align the PCB board with the mounting position on the back of the insulating shell 1, and gently press to allow the pre-positioning clips to engage with the PCB board slots, achieving quick pre-positioning and fixing. At this time, the circular hole 31 of the PCB board automatically aligns with the conductive plate pins, eliminating the need for manual fine-tuning. After fixing, the conductive plate pins vertically penetrate the circular hole 31, fitting snugly against the hole wall to achieve assembly, making subsequent soldering operations convenient and efficient. When it is necessary to inspect or replace components, the PCB board can be easily removed by gently prying open the elastic clips, making disassembly and assembly convenient without damaging the main structure or conductive plates.

[0041] Beneficial effects: It solves the problems of traditional PCB board assembly, such as lack of positioning, large alignment deviations, and reliance on manual calibration and tooling assistance. It significantly reduces the difficulty of assembly operations, improves assembly efficiency and alignment accuracy, and eliminates defects such as soldering misalignment, poor contact, and cold solder joints caused by alignment deviations. The detachable snap-fit ​​structure facilitates later product maintenance, repair, and component replacement, reducing after-sales maintenance costs. At the same time, the pre-positioning structure ensures the consistency of batch product assembly and improves product yield.

[0042] In one embodiment, the pin structure 22 is a flat, straight-through structure, and the outer contour of the pin is adapted to the inner contour of the circular hole 31 of the micro PCB board 3.

[0043] Specifically, the pin structure 22 at the lower end of the beryllium copper piercing conductive sheet 2 is an integrated flat straight-insertion structure. The pin is flat and strip-shaped with a flat end face and smooth sidewalls, without any protrusions, burrs, or bends. The outer contour dimensions, thickness, and width of the pin are adapted to the inner contour of the circular hole 31 on the micro PCB board 3. The circular hole 31 adopts a flat adaptable opening structure that perfectly matches the shape of the pin, rather than a traditional circular opening. The flat straight-insertion structure ensures that after the pin is inserted into the circular hole 31, the hole wall and the sidewall of the pin are fully fitted, resulting in a large contact area, small assembly gap, and extremely strong positioning stability.

[0044] Working principle: During the forming process of the conductive sheet, the lower end is directly stamped to form a flat, straight-insertion pin, ensuring the flatness and dimensional accuracy of the pin. During assembly, the flat pin is vertically inserted into the flat circular hole 31 of the PCB board. The side wall of the pin fits tightly against the inner wall of the circular hole 31, achieving a wobbly positioning. Compared with the point contact and larger gap between the circular pin and the circular hole 31, the flat structure can effectively limit the radial wobble and rotational offset of the pin, ensuring the stability of the pin position before and after soldering, and providing a structural basis for stable conductivity and soldering fixation.

[0045] Beneficial effects: The flat, through-hole adapter structure improves the fit and positioning stability of the conductive sheet and the PCB board, eliminating the problems of large gaps, easy wobbling, and soldering misalignment associated with traditional round pins, thus improving soldering quality and conductivity stability. The integrated flat pin structure is simple to mold and has high dimensional accuracy, making it suitable for automated assembly operations and mass production. Furthermore, the larger contact area further reduces on-resistance and improves current-carrying stability.

[0046] In one embodiment, the receiving groove 11 is a long, flat groove structure adapted to the shape of the flat braided wire, and the width of the groove is set to match the width of the flat braided wire.

[0047] Specifically, the receiving groove 11 inside the insulating shell 1 is a long, flat, integral groove structure. The length, width, and thickness of the groove are optimized according to the specifications of conventional flat braided wire. The width of the groove matches the width of standard flat braided wire, and the thickness of the groove is adapted to the overall thickness of the wire. The inner wall of the groove is flat and smooth, without any protrusions or steps, allowing the flat braided wire to be placed flat and snugly. The long, strip-shaped groove structure completely wraps around the wire connection area, providing all-round limiting support for the wire and preventing the wire from being suspended, bent, or warped.

[0048] Working principle: During assembly, the flat braided wire can be completely and flatly embedded into the long, flat receiving groove 11. The groove provides all-round support and restraint for the bottom and sides of the wire, ensuring that the wire is placed flat and in a regular posture, without any local warping, twisting, or bending. The groove's size-adaptive design ensures that the wire fits tightly to the groove, and the wire is evenly stressed under pressure, avoiding deformation and insulation damage caused by localized stress concentration. This provides a flat working foundation for the even piercing of the upper piercing edge 21.

[0049] Beneficial effects: It solves the problems of mismatched slot dimensions, easy warping and twisting of wires, and uneven puncture force in traditional connectors, ensuring that the wires are assembled in a neat posture and the force is even, improving the consistency and stability of puncture and avoiding problems such as poor puncture and contact failure caused by wire posture deviation. At the same time, the long, flat slot is compatible with mainstream flat braided wires, which is highly versatile, simple and durable in structure, and not easily deformed after long-term use, effectively improving product compatibility and usage stability.

[0050] In one embodiment, the snap-fit ​​structure 111 is provided with a self-locking engagement portion.

[0051] Specifically, the snap-fit ​​structure 111 integrates a self-locking snap-fit ​​part. The snap-fit ​​is made of highly elastic insulating plastic, and the snap-fit ​​part is a self-locking structure with concave and convex fittings. After the downward stroke is completed, it can automatically snap and lock, without the need for additional bolts or glue for fixation. The self-locking snap-fit ​​part is located on both sides of the snap-fit ​​and is adapted to the slots of the insulating shell 1. After the downward stroke is completed, the snap-fit ​​is tightly engaged with the shell to form a rigid limiting structure, which can continuously maintain the downward pressing state without any springback, loosening, or lifting problems.

[0052] Working principle: The manual pressing of the buckle clamping structure 111 causes the buckle to automatically engage with the locking grooves of the insulating shell 1 when pressed down to the preset working stroke. This mechanical self-locking locks the buckle's pressing position, ensuring that the buckle continuously applies uniform pressure to the flat braided wire below, guaranteeing that the wire remains in contact with the groove and the conductive blade edge remains tightly in contact with the conductive wire. To disassemble the wire, simply press the buckle unlocking position to release the self-locking, lift the buckle, and remove the wire. Disassembly and assembly are convenient.

[0053] Beneficial effects: By replacing the traditional elastic rebound structure with a mechanical self-locking structure, the defects of ordinary clips such as elastic fatigue, loosening during rebound, and wire detachment and displacement after long-term use are solved. This ensures tight contact between the wire and the conductive sheet during long-term use, eliminating problems such as poor contact and signal interruption under vibration and temperature difference environments. The self-locking structure requires no auxiliary fixing parts, making assembly efficient, disassembly convenient, and the structure highly durable, thus improving product lifespan and adaptability to various operating conditions, including automotive and industrial control applications with complex vibrations.

[0054] In one embodiment, the beryllium copper piercing conductive sheet 2 has a gold-plated layer on its surface.

[0055] Specifically, the beryllium copper piercing conductive sheet 2 has a dense and uniform gold plating layer covering its entire surface. The gold plating layer is of uniform thickness, has strong adhesion, and is free from peeling or incomplete plating defects. It completely covers the cutting edge, contact area, and pin soldering area, providing all-around protection for the conductive sheet. The gold plating layer has excellent conductivity, oxidation resistance, and corrosion resistance; it will not oxidize or rust, nor will it be corroded by moisture. At the same time, it can effectively reduce metal contact resistance and improve conductivity.

[0056] Working principle: The gold plating layer covers all conductive contact points of the conductive sheet, isolating the beryllium copper substrate from oxidation and corrosion by air, moisture, and oil. Long-term use maintains a smooth surface and stable conductivity of the conductive sheet. Simultaneously, the low resistance of the gold plating reduces contact resistance between the conductive sheet and the conductive wires, and between the conductive sheet and the PCB board, minimizing signal transmission loss and ensuring the stability of electrical signals and current transmission. This avoids problems such as increased contact resistance, signal attenuation, and transmission interruption caused by oxidation and corrosion.

[0057] Beneficial effects: Effectively solves industry pain points such as easy oxidation and corrosion of copper conductive sheets, increased resistance over long-term use, and unstable conductivity. Improves the weather resistance, corrosion resistance, and service life of conductive sheets, making them suitable for complex working environments such as humidity, high temperature, and dust. The low resistance characteristics of the gold plating layer further optimize conductivity, reduce signal transmission loss, improve the accuracy and stability of equipment signal transmission, eliminate equipment failures caused by oxidation, and enhance the long-term reliability of the product.

[0058] In one embodiment, the insulating shell 1 is made of high-temperature resistant and flame-retardant plastic material.

[0059] Specifically, the insulating outer shell 1 is integrally molded from modified high-temperature resistant and flame-retardant plastic material. This material possesses excellent insulation, high-temperature resistance, and flame-retardant properties, meeting industry standards for flame retardancy and effectively preventing the spread of open flames. Its high-temperature resistance range covers the typical operating high-temperature range of electronic equipment, and it will not soften, deform, age, or crack under long-term high-temperature environments. Simultaneously, the material has high insulation resistance, effectively isolating the risk of leakage and cross-current, protecting the internal conductive structure for safe and stable operation.

[0060] Working Principle: During operation, the heat and instantaneous high temperatures generated inside the electronic equipment will not cause the insulating outer shell 1 to soften or deform. The shell maintains its structural integrity and dimensional stability, ensuring the assembly accuracy and structural position of the internal conductive sheets, wires, and PCB board remain unchanged. Simultaneously, the shell's high insulation and flame-retardant properties isolate the internal conductive structure from the equipment housing and surrounding components, eliminating the risk of leakage, short circuits, and fire. In the event of instantaneous overheating or sparking, the shell effectively prevents the malfunction from escalating.

[0061] Beneficial effects: It solves the shortcomings of traditional connector plastic shells, such as poor high-temperature resistance, easy aging and deformation, lack of flame retardancy, and weak insulation performance. It is suitable for the closed, high-temperature working environment inside electronic equipment, effectively improving the safety, stability, and aging resistance of the product. The material has excellent insulation properties, eliminating the safety hazards of leakage, cross-current, and short circuits. The flame-retardant properties can improve the safety level of equipment use, reduce the risk of equipment failure and safety accidents, and are suitable for high-reliability scenarios such as industrial electronics, automotive electronics, and smart homes.

[0062] This invention features high structural integration, simple assembly, and reliable connection. The integrated snap-fit ​​structure enables flat braided wires to achieve rapid conduction without stripping or tinning, simplifying processes and improving production efficiency. The 53° three-edge piercing structure can pierce the braided insulation layer without damaging the conductive wires, and the limiting slot prevents wire displacement and short circuits, improving conductivity stability. The PCB pre-positioning structure achieves tooling-free alignment, ensuring consistent soldering. Self-locking clamping, a gold-plated conductive layer, and a flame-retardant, high-temperature resistant shell make the product resistant to loosening, corrosion, and heat, ensuring stable operation under complex conditions. It overcomes the shortcomings of traditional structures, such as poor contact and aging failure, and is suitable for various electronic wire harness connections, significantly improving reliability.
