Description

Technical Field

[0001] This invention belongs to the field of data cable technology, specifically relating to a data cable interface reinforcement structure and preparation method that is resistant to bending and breakage. Background Technology

[0002] Data cables are indispensable connection accessories for the daily use of electronic devices. They are mainly used for the connection and conduction between devices and power sources or other devices. They are made of high-quality materials suitable for conduction requirements, taking into account both flexibility and durability. They are easy to store and carry and can adapt to the bending requirements of different usage scenarios. No additional assembly is required during use. Simply connect the two ends to the corresponding device interfaces to realize power transmission or signal transmission. They are convenient and efficient to operate and widely compatible with various consumer electronic devices, providing stable and reliable connection support for the daily battery life and data interaction of the devices. However, frequent plugging and unplugging, bending and twisting of data cables in daily use will cause the material at the connection between the interface and the cable body to be subjected to continuous mechanical stress. Over time, this can easily lead to fatigue damage to the internal conductor and the outer sheath, eventually causing breakage and affecting the normal use of the data cable.

[0003] Most existing data cable interfaces lack effective bending and breakage resistance structures, or only possess simple ones. These structures are often one-piece grooved protective sleeves. While these structures can disperse bending stress to some extent, they lack rotation capabilities. During daily use, the wires at the interface often twist due to device movement and pulling. These sleeve-type structures cannot rotate in the direction of twisting, thus failing to eliminate torsional stress. A few data cable interfaces with rotating structures use end spring contacts and concentric ring conductive rails to ensure continuity during rotation. However, when the interface rotates, the end spring contacts rub directly against the concentric ring conductive rails, causing rapid wear and resulting in a shorter lifespan for these data cables.

[0004] Most existing data cable interfaces do not have an arc-shaped intersection structure. The intersection between the data cable and the protective structure is circular, and the circumference of this circle is equal to the cross-sectional circumference of the data cable. When the data cable is pulled axially, because the intersection between the data cable and the protective structure is short, the tension is concentrated on this circular structure, which makes it easy for the connection between the data cable and the protective structure to break. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a data cable interface reinforcement structure and preparation method that is resistant to bending and breakage.

[0006] The technical solution adopted to solve the above technical problems is:

[0007] Firstly, a technical solution is provided: a data cable interface reinforcement structure that is resistant to bending and breakage, including a plug mechanism and a rotating conductor mechanism. The plug mechanism includes conductive terminals, a wrapping mechanism is fixed to the top of the plug mechanism, a conductive disk mechanism is fixed to the top of the wrapping mechanism, and the conductive disk mechanism includes a disk body. Multiple conductive copper rings are embedded and fixed on the inner side of the disk body, and a cylindrical conductor is fixed at the axis of the disk body.

[0008] The top of the packaging mechanism is rotatably connected to a rotating disk mechanism, which includes a rotating disk body and a rotating conductor mechanism fixed on the rotating disk mechanism. The rotating conductor mechanism includes a conductor assembly shell, which has multiple assembly cavities. The bottom of the assembly cavity is connected to a conductive ball, and a conductive spring is connected to the conductive ball.

[0009] A wire mechanism is welded onto the rotating conductor mechanism, and a protective mechanism is fixed to the outside of the wire mechanism. The protective mechanism includes a protective cover, and an anti-bending sleeve is integrally formed at the top of the protective cover. An arc-shaped contraction part is integrally formed at the top of the anti-bending sleeve.

[0010] Furthermore, a PCB board is fixed inside the conductive terminal, and multiple first solder contact points are fixed on the PCB board, with PCB solder wires soldered and fixed on the first solder contact points.

[0011] Through the above technical solution, the PCB board is the main control PCB board for the data line, which enables the device to provide signal and power management functions, and the PCB solder wires can connect the PCB board to the circuit.

[0012] Furthermore, the packaging mechanism includes a packaging shell body fixed to the conductive terminals, the packaging shell body being provided with terminal mounting holes, and multiple dispensing areas being opened on the inner side of the terminal mounting holes.

[0013] The above technical solution allows for the secure fixing of conductive terminals to the inside of terminal mounting holes by applying adhesive in the dispensing area. The adhesive, after being squeezed, can also fill the gap between the conductive terminals and the terminal mounting holes, thereby effectively preventing dust from entering the device through the gaps.

[0014] Furthermore, the bottom end of the disk body is integrally formed with multiple reinforcing connecting ribs, and the top ends of the PCB solder wires are respectively welded and fixed to each conductive copper ring. The top of the conductive copper ring is grooved, and the cross-section of the groove is arc-shaped. The multiple conductive copper rings are concentric.

[0015] Through the above technical solutions, the reinforced connecting ribs can effectively improve the structural strength of the disk body, the disk body can provide an installation slot for the conductive copper ring, the annular convex rib structure on the disk body can effectively prevent the conductive copper rings from contacting each other and causing a short circuit, and the annular groove structure on the top of the conductive copper ring can better fit with the conductive ball, improving the current carrying capacity at the contact point between the conductive ball and the conductive copper ring.

[0016] Furthermore, a fixing groove is provided on the rotating disk body, and a rotating connector is fixed at the axis of the rotating disk body. The rotating connector is made of conductive material, and a second welding contact point is fixed at the top of the rotating connector.

[0017] Through the above technical solution, the rotating connector can be made of materials such as carbon bronze alloy that have conductive and wear-resistant properties. While having good conductivity, it can also avoid wear of the rotating connector caused by long-term rotation. The bottom of the rotating connector is welded and fixed to the cylindrical conductor, so that the cylindrical conductor and the second welding contact point are always conductive when the rotating disk rotates.

[0018] Furthermore, the top of the conductor assembly shell is inlaid with a plurality of third welding contact points, and the top of the conductive spring is welded and fixed to the third welding contact points.

[0019] Through the above technical solution, the bottom end of the conductive ball is rolled and connected to the conductive copper ring, and the conductive spring contacts the conductive ball. Therefore, the conductive copper ring is connected to the third welding contact point. When the rotating disk rotates, the conductor assembly shell is also driven to rotate. At this time, the conductive ball will roll along the top of the conductive copper ring. Therefore, the device has the function of rotating and energizing, which can effectively avoid the twisting of the line at the data cable interface, and thus prevent the outer sheath of the line from breaking due to long-term twisting. The conductive spring has a downward elastic thrust on the conductive ball, so that the conductive ball can always contact the conductive copper ring and avoid the occurrence of loose connection. The rolling contact method of the conductive ball can effectively reduce the wear of the conductive ball, thereby improving the service life of the device. The multiple assembly cavities are independent of each other, which can effectively prevent the conductors from contacting each other under external impact or external extrusion, effectively improving the safety of the device.

[0020] Furthermore, the conductor mechanism includes multiple conductor bodies, which are respectively welded to the top of the second and third welding contact points. The conductor bodies are wrapped with an insulating inner layer, and the insulating inner layer is wrapped with an outer sheath.

[0021] Through the above technical solution, the inner insulation layer can effectively prevent short circuits between the individual conductors, while the outer sheath can improve the overall protection effect of the line. The top of the conductor can be welded and fixed to the other end of the data cable connector.

[0022] Furthermore, the anti-bending sheath has multiple transverse grooves, which are distributed in an alternating pattern.

[0023] Through the above technical solution, the anti-bending sheath is fixed in one piece with the rotating conductor mechanism and the wire mechanism. When the data cable is bent, the transverse groove will bend slightly first, thereby dispersing the bending force and avoiding stress concentration in one place, which would cause the interface to break. The staggered distribution structure of the transverse grooves makes the device resistant to bending and breaking in all directions.

[0024] Furthermore, the top of the arc-shaped contraction portion is contracted, and the connection between the top of the arc-shaped contraction portion and the outer sheath is arc-shaped.

[0025] Through the above technical solution, the contraction structure at the top of the arc-shaped contraction section and the arc-shaped cut-off structure on both sides effectively increase the intersection length at the connection between the conductor mechanism and the protection mechanism. This allows the tensile force to be distributed along a longer intersection line when the device is subjected to axial tension, thereby reducing the tensile force borne at each point on the intersection line and effectively improving the tensile strength of the device.

[0026] Secondly, based on the first aspect mentioned above, a method for preparing a data cable interface reinforcement structure that is resistant to bending and breakage is also provided, including the following specific steps:

[0027] Step 1: The outer shell, the disk body, the rotating disk, and the conductor assembly shell are manufactured by injection molding, and multiple conductive copper rings of different specifications are produced by stamping.

[0028] Step 2: Apply adhesive to the dispensing area and insert the plug mechanism into the terminal mounting hole for bonding and fixing;

[0029] Step 3: Assemble multiple conductive copper rings into the tray body, and fix the conductive copper rings to the tray body by interference fit or glue application. Then, weld the top of the PCB solder wire to the bottom of the conductive copper ring.

[0030] Step 4: Insert the conductive ball into the assembly cavity from the top, weld the conductive spring to the third welding contact point, press the conductive spring downward into the assembly cavity, and fix the third welding contact point to the conductor assembly shell by interference fit or glue application.

[0031] Step 5: Install the assembled rotating conductor mechanism in the fixing groove and fix the rotating conductor mechanism by applying glue. Install the rotating disk mechanism on the top of the wrapping mechanism. The rotating disk mechanism and the wrapping mechanism are connected by an interference fit. At this time, the conductive ball and the conductive copper ring are in rolling contact.

[0032] Step 6: Weld the bottoms of the multiple wire bodies to the second and third welding contact points respectively;

[0033] Step 7: The protective mechanism is formed on the outside of the rotating conductor mechanism and the wire mechanism by overmolding, so that the top of the protective mechanism is fixed to the wire mechanism and the bottom of the protective mechanism is fixed to the rotating conductor mechanism. This completes the fabrication of the device.

[0034] The beneficial effects of this invention are as follows:

[0035] 1. The present invention achieves rotary power supply by setting up a conductive disk mechanism, a rotating disk mechanism and a rotating conductor mechanism, thereby effectively avoiding breakage at the interface due to torsional stress, effectively reducing the frictional loss of its rotating power supply mechanism, and preventing mutual interference between conductors;

[0036] 2. By incorporating a protective mechanism, this invention effectively improves the device's resistance to bending and tension, thereby reducing the probability of breakage at the interface due to bending and tension, and extending its service life. Attached Figure Description

[0049] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0050] like Figures 1-11 As shown, a data cable interface reinforcement structure that is resistant to bending and breakage includes a plug mechanism 1 and a rotating conductor mechanism 5. The plug mechanism 1 includes a conductive terminal 101, and a PCB board 102 is fixed inside the conductive terminal 101. Multiple first solder contact points 103 are fixed on the PCB board 102, and PCB solder wires 104 are soldered and fixed on the first solder contact points 103. The PCB board 102 is the main control PCB board 102 of the data cable, enabling the device to provide signal and power management functions. The PCB solder wires 104 can connect the PCB board 102 to the circuit.

[0051] like Figure 1 and Figure 4 As shown, the plug mechanism 1 includes a conductive terminal 101. A wrapping mechanism 2 is fixed to the top of the plug mechanism 1. The wrapping mechanism 2 includes a wrapping shell body 201 fixed to the conductive terminal 101. A terminal mounting hole 202 is provided on the wrapping shell body 201. Multiple glue dispensing areas 203 are provided on the inner side of the terminal mounting hole 202. By dispensing glue in the glue dispensing areas 203, the conductive terminal 101 can be firmly fixed to the inner side of the terminal mounting hole 202. After the glue is squeezed, it can also fill the gap between the conductive terminal 101 and the terminal mounting hole 202, thereby effectively preventing dust from entering the device from the gap.

[0052] like Figure 1 , Figure 5 and Figure 6As shown, a conductive disk mechanism 3 is fixed to the top of the wrapping mechanism 2. The conductive disk mechanism 3 includes a disk body 301, with multiple conductive copper rings 302 embedded and fixed inside the disk body 301. A cylindrical conductor 304 is fixed at the axis of the disk body 301. Multiple reinforcing connecting ribs 303 are integrally formed at the bottom of the disk body 301. The top of the PCB solder wire 104 is welded and fixed to each conductive copper ring 302. The top of the conductive copper ring 302 is grooved, and the cross-section of the groove is arc-shaped. The conductive copper rings 302 are concentric in structure. The reinforcing connecting ribs 303 can effectively improve the structural strength of the disk body 301. The disk body 301 can provide mounting slots for the conductive copper rings 302. The annular protruding rib structure on the disk body 301 can also effectively prevent the conductive copper rings 302 from contacting each other and causing a short circuit. The annular groove structure on the top of the conductive copper rings 302 can better fit with the conductive balls 503, improving the current carrying capacity at the contact point between the conductive balls 503 and the conductive copper rings 302.

[0053] like Figure 1 and Figure 7 As shown, a rotating disk mechanism 4 is rotatably connected to the top of the wrapping mechanism 2. The rotating disk mechanism 4 includes a rotating disk body 401, a fixing groove 402 on the rotating disk body 401, and a rotating connector 403 fixed at the axis of the rotating disk body 401. The rotating connector 403 is made of conductive material, and a second welding contact point 404 is fixed at the top of the rotating connector 403. The rotating connector 403 can be made of materials with conductive and wear-resistant properties, such as carbon bronze alloy. It has good conductivity and can also prevent wear of the rotating connector 403 caused by long-term rotation. The bottom of the rotating connector 403 is welded and fixed to the cylindrical conductor 304, so that the cylindrical conductor 304 and the second welding contact point 404 are always conductive when the rotating disk body 401 rotates.

[0054] like Figure 1 and Figure 8As shown, a rotating conductor mechanism 5 is fixed on the rotating disk mechanism 4. The rotating conductor mechanism 5 includes a conductor assembly shell 501, which has multiple assembly cavities 502. A conductive ball 503 is rolledly connected to the bottom of each assembly cavity 502, and a conductive spring 504 is rolledly connected to each conductive ball 503. Multiple third welding contact points 505 are embedded and fixed at the top of the conductor assembly shell 501. The top of the conductive spring 504 is welded to the third welding contact points 505. The bottom of the conductive ball 503 is rolledly connected to a conductive copper ring 302. The conductive spring 504 contacts the conductive ball 503, thus the conductive copper ring 302 is connected to the third welding contact points 505. When the rotating disk 401 rotates, the conductor assembly shell 501 also... Driven to rotate, the conductive ball 503 rolls along the top of the conductive copper ring 302, thus enabling the device to rotate and conduct electricity. This effectively prevents the wiring at the data cable interface from twisting, thereby preventing the outer sheath of the wiring from breaking due to long-term twisting. The conductive spring 504 exerts a downward elastic force on the conductive ball 503, ensuring that the conductive ball 503 always contacts the conductive copper ring 302, preventing incomplete connections. The rolling contact method of the conductive ball 503 effectively reduces wear, thereby improving the service life of the device. The multiple assembly cavities 502 are independent of each other, effectively preventing the conductors from contacting each other under external impact or external pressure, thus effectively improving the safety of the device.

[0055] like Figure 1 and Figure 9 As shown, a conductor mechanism 6 is welded onto the rotating conductor mechanism 5. The conductor mechanism 6 includes multiple conductor bodies 601. The conductor bodies 601 are welded to the top of the second welding contact point 404 and the third welding contact point 505, respectively. The conductor bodies 601 are wrapped with an insulating inner layer 602, and the insulating inner layer 602 is wrapped with an outer sheath 603. The insulating inner layer 602 can effectively prevent short circuits between the conductor bodies 601, while the outer sheath 603 can improve the overall protection effect of the line. The top of the conductor body 601 can be welded and fixed to the other end of the data cable connector.

[0056] like Figure 1 , Figure 10 and Figure 11As shown, a protective mechanism 7 is fixed to the outside of the conductor mechanism 6. The protective mechanism 7 includes a protective cover 701. An anti-bending sleeve 702 is integrally formed at the top of the protective cover 701. An arc-shaped contraction part 704 is integrally formed at the top of the anti-bending sleeve 702. Multiple transverse grooves 703 are provided on the anti-bending sleeve 702, and the transverse grooves 703 are distributed in an alternating pattern. The top of the arc-shaped contraction part 704 is contracted, and the connection between the top of the arc-shaped contraction part 704 and the outer sheath 603 is arc-shaped. The anti-bending sleeve 702 is integrally fixed to the rotating conductor mechanism 5 and the conductor mechanism 6. When the data cable contacts... When bent, the transverse groove 703 will bend slightly first, thereby dispersing the bending tensile force and avoiding stress concentration in one place, which could lead to breakage at the interface. The staggered distribution structure of the transverse groove 703 gives the device the ability to resist bending and breakage in all directions. The contraction structure at the top of the arc-shaped contraction part 704 and the arc-shaped cut-off structure on both sides effectively increase the intersection length at the connection between the conductor mechanism 6 and the protection mechanism 7. This allows the tensile force to be distributed along a longer intersection line when the device is subjected to axial tension, thereby reducing the tensile force borne at each point on the intersection line and effectively improving the tensile strength of the device.

[0057] When using this invention, the user inserts the plug mechanism 1 into the device's socket. When the device rotates, the wrapping mechanism 2 and the rotating disk mechanism 4 rotate relative to each other, effectively preventing the wire at the interface from twisting and reducing the possibility of the wire breaking due to torsional stress. During this process, the conductive disk mechanism 3 and the rotating conductor mechanism 5 can ensure that the internal circuit of the device is always conductive. When the device is bent, the anti-bending sleeve 702 can effectively disperse the bending stress and effectively prevent the wire from breaking due to bending. When the conductor mechanism 6 is pulled during use, the arc-shaped contraction part 704 can effectively disperse the pulling force, thereby effectively reducing the probability of the connection between the conductor mechanism 6 and the protection mechanism 7 breaking due to pulling.

[0058] A method for preparing a data cable interface reinforcement structure that is resistant to bending and breakage includes the following specific steps:

[0059] Step 1: The encapsulating shell body 201, the disk body 301, the rotating disk body 401 and the conductor assembly shell 501 are processed by mold injection molding process, and multiple conductive copper rings 302 of different specifications are produced by stamping process.

[0060] Step 2: Apply adhesive to the adhesive application area 203 and insert the plug mechanism 1 into the terminal mounting hole 202 for bonding and fixing;

[0061] Step 3: Assemble multiple conductive copper rings 302 into the disk body 301, and fix the conductive copper rings 302 to the disk body 301 by interference fit or glue application. Then, weld the top of the PCB solder wire 104 to the bottom of the conductive copper ring 302.

[0062] Step 4: Insert the conductive ball 503 into the assembly cavity 502 from the top, weld the conductive spring 504 to the third welding contact point 505 and fix it, then press the conductive spring 504 downward into the assembly cavity 502, and fix the third welding contact point 505 to the conductor assembly shell 501 by interference fit or glue application.

[0063] Step 5: Install the assembled rotating conductor mechanism 5 in the fixing groove 402 and fix the rotating conductor mechanism 5 by applying glue. Install the rotating disk mechanism 4 on the top of the wrapping mechanism 2. The rotating disk mechanism 4 and the wrapping mechanism 2 are rotated with an interference fit. At this time, the conductive ball 503 and the conductive copper ring 302 are in rolling contact.

[0064] Step 6: Weld the bottoms of the multiple conductor bodies 601 to the second welding contact point 404 and the third welding contact point 505 respectively;

[0065] Step 7: The protective mechanism 7 is formed on the outside of the rotating conductor mechanism 5 and the wire mechanism 6 by overmolding, so that the top end of the protective mechanism 7 is fixed to the wire mechanism 6 and the bottom end is fixed to the rotating conductor mechanism 5, thus completing the preparation of the device.
