Abstract
Description
Technical Field
[0001] The present disclosure generally relates to the field of composite cable connection technology, and in particular to a power cable connection device and method. Background Art
[0002] In the field of modern power communications, the application of power communication composite cables is becoming more and more widespread. They can transmit power and communication signals at the same time, providing a strong guarantee for the stable operation of various systems.
[0003] However, the splicing problem of composite cables has always been a key problem that needs to be solved urgently in the industry.
[0004] The traditional composite cable splicing method usually adopts the step-by-step operation of metal wire and optical fiber. This method has many disadvantages. First, it is extremely inefficient, requires a lot of time and labor costs, and increases the construction period and operating costs. Secondly, the core alignment accuracy is poor, and deviations are prone to occur during the manual core alignment process, resulting in a decrease in signal transmission quality and affecting the stability of communication and power transmission.
[0005] In addition, the optical fiber is easily damaged during the splicing process. Since the processing procedures of the metal wire and the optical fiber are separated and the operation is complicated, the optical fiber may break if you are not careful during the operation, which will seriously affect the overall performance of the cable.
[0006] Moreover, it is difficult to accurately control the stripping range of the metal wire with existing splicing technology, and irreparable damage may be caused to the internal optical fiber when stripping the metal wire.
[0007] At the same time, traditional welding methods cannot achieve uniform circumferential welding of metal wires, resulting in uneven welding quality and affecting the long-term performance of the cable.
[0008] Therefore, there is an urgent need for a composite cable splicing technology that is efficient, high-precision and can avoid damaging optical fibers to meet the power communication industry's demand for reliable splicing of composite cables. Summary of the invention

[0101] According to another aspect of the present disclosure, a wiring method is provided, including the following steps:
[0102] S1. Pretreat the docking end of the composite cable: Manually level the docking end interfaces of the two composite cables, and cut the skin of the exposed part of the metal wire;
[0103] S2. Core alignment and calibration: Install the pretreated composite cables into the symmetrically arranged core-twisting mechanisms respectively, and synchronously rotate the two groups of composite cables through the twisting drive assembly to axially align the internal metal wires and optical fibers respectively;
[0104] S3. Metal wire stripping and positioning: Drive the first telescopic mechanism of the two groups of metal wire stripping structures to feed obliquely towards the composite cable, and use the electromagnetic induction sensor on the stripping block to detect the position of the metal wire.

After the fusion is completed, scan and detect the fusion integrity along the optical fiber axis through the optical time domain reflectometer;
[0107] S6. Metal wire reset welding: After confirming that the optical fiber fusion splicing is qualified, retract the stripping block to make the metal wire reset and contact, and drive the rotary spot welding mechanism to continuously perform spot welding and fixation around the metal wire along the arc-shaped servo slide rail.
[0108] The embodiments of the present disclosure have the following advantages.
[0109] Two groups of core-alignment torsion mechanisms symmetrically clamp both ends of the composite cable. The composite cable is driven to rotate synchronously around its axis by the torsion drive assembly, so that the internal metal wire and the optical fiber are axially aligned, ensuring subsequent connection accuracy. The first telescopic mechanism of the metal wire stripping structure pushes the stripping block to incline and feed towards the composite cable, and uses the mechanical action of the stripping block to push the metal wire to both sides. At the same time, the fusion splicer mounting arm drives the optical fiber fusion splicer to move to the exposed optical fiber position for fusion splicing. After completing the optical fiber fusion splicing, the rotary spot welding mechanism slides around the metal wire along the arc-shaped servo slide rail, and the spot welding assembly is driven by the rotary drive assembly to continuously rotate and perform spot welding around the axis of the composite cable, realizing circumferential uniform welding of the metal wire. The optical fiber fusion splicing and the metal wire welding are integrated and completed by the same device. The fusion splicer mounting arm and the rotary spot welding mechanism are executed step by step to avoid process interference. The core-alignment torsion mechanism calibrates the axial positions of the internal metal wire and the optical fiber in the composite cable by synchronous rotation, avoiding the deviation of traditional manual core alignment and improving the connection reliability. The inclined feeding design of the metal wire stripping structure can accurately control the stripping range of the metal wire to prevent damage to the optical fiber. The rotary spot welding mechanism realizes rapid and continuous circumferential welding of the metal wire through the coordinated movement of the arc-shaped servo slide rail and the rotary drive assembly, greatly improving the welding efficiency and consistency. The optical fiber fusion splicer and the metal wire welding module are integrated into the same device, reducing the process switching time. The inclined linkage design of the stripping block and the first telescopic mechanism provides a stable operation space for optical fiber fusion splicing while pushing the metal wire away, reducing the risk of optical fiber fracture. The fusion splicer mounting arm is independently arranged on the upper part of the mounting frame to avoid spatial interference with the metal wire welding module. The arc-shaped servo slide rail supports multi-angle welding path adjustment of the rotary spot welding mechanism, adapting to different composite cable diameters and metal wire arrangement forms, enhancing the versatility of the device, improving the technical problems of low operation efficiency, poor core alignment accuracy, and easy damage to optical fibers in traditional composite cable connection, and being applicable to the high-efficiency and high-precision connection scenario of power communication composite cables.

[0179] In the above embodiments, when the torsion drive assembly 3 works, the output shaft of the first motor 33 rotates and drives the first drive gear 32 to rotate. When the first drive gear 32 rotates, it drives the driven gear 34 meshing with it to rotate. Then, the first arc-shaped rack 35 meshing with the driven gear 34 rotates around the central axis of the two C-shaped clamping arms 11 to make a circular motion, so that the two C-shaped clamping arms 11 can twist the composite cable 9 respectively. When the two C-shaped clamping arms 11 rotate, the two groups of positioning sliders 36 slide in the two arc-shaped chutes 14 respectively.
[0180] Please refer to Figures 1-9 , in some embodiments, the first telescopic mechanism 41 includes:
[0181] A base 411, which is installed on the lower surface of the mounting frame 2, and the upper part of the base 411 is inclined backward and points to the composite cable 9;
[0182] Two groups of first electric push rods 412, which are installed at intervals on the inclined surface of the upper part of the base 411, and the telescopic ends are connected to the peeling block 42;
[0183] A guide ring 413, which is sleeved on the outer wall of the first electric push rod 412;
[0184] A guide rod 414, one end of which is connected to the peeling block 42 and the other end is connected to the end wall of the guide ring 413;
[0185] The peeling block 42 includes:
[0186] Two groups of diamond-shaped vertical plates 421, with the included angle on the side close to the composite cable 9 open; where
[0187] The guide rod 414 penetrates through the included angle at one end of the two groups of diamond-shaped vertical plates 421 far from the open end;
[0188] A triangular prism 422, with both ends arranged in the inner rings of the two groups of diamond-shaped vertical plates 421;
[0189] One of the side edges of the triangular prism 422 is arranged close to the guide rod 414 and is connected to the guide rod 414;
[0190] A bottom plate 423, with both ends connected to one ends of the two diamond-shaped vertical plates 421 close to the guide ring 413, and the middle section of the bottom plate 423 is connected to the telescopic end of the first electric push rod 412;
[0191] The arc-shaped servo slide rail 5 is arranged between the two groups of peeling blocks 42, and the curved surface of the arc-shaped servo slide rail 5 faces the open end of the diamond-shaped vertical plate 421;
[0192] Two groups of curved spring pieces 424, symmetrically arranged on the inner walls of the diamond-shaped vertical plates 421, and the curved surfaces of the two groups of curved spring pieces 424 face the optical fiber 91 of the composite cable 9;
[0193] The electromagnetic induction sensor 425 is installed at the open end of the diamond-shaped vertical plate 421;
[0194] The optical time domain reflectometer 426, the light-emitting diode at the detection end is arranged at the open end of the diamond-shaped vertical plate 421;
[0195] The control unit is electrically connected to the electromagnetic induction sensor 425 and the first electric push rod 412, and is used to control the first electric push rod 412 to stop moving when the electromagnetic induction sensor 425 detects the disappearance of the metal wire 92;
[0196] The data processing module is connected to the optical time domain reflectometer 426, and is used to calculate the relative distance between the optical fiber 91 and the metal wire 92 according to the measurement data of the optical time domain reflectometer 426.
[0197] In the above embodiment, when the first telescopic mechanism 41 works, the first electric push rod 412 extends, driving the peeling block 42 to feed towards the composite cable 9. During this process, the first electric push rod 412 pushes the open angle of the diamond-shaped vertical plate 421 towards the two metal wires 92. When the diamond-shaped vertical plate 421 abuts between the two metal wires 92, the first electric push rod 412 continues to extend, so that the first electric push rod 412 continues to push the diamond-shaped vertical plate 421 to slide on the guide rod 414 towards the triangular prism 422, so that the inner walls on both sides of the angle at the end of the diamond-shaped vertical plate 421 close to the triangular prism 422 move along the two adjacent faces of the triangular prism 422, so that the adjacent faces of the triangular prism 422 push the angle of the diamond-shaped vertical plate 421 to continuously increase, so that the vertical plates on both sides of the open end of the diamond-shaped vertical plate 421 push the two metal wires 92 to expand outwards, achieving the purpose of separating the metal wire 92. When the diamond-shaped vertical plate 421 completely separates the two metal wires 92, the two groups of curved spring pieces 424 arranged in the diamond-shaped vertical plate 421 are clamped against the outer wall of the optical fiber 91 to stabilize the optical fiber 91. During the movement of the diamond-shaped vertical plate 421, the electromagnetic induction sensor 425 detects the state of the metal wire 92 in real time. When the metal wire 92 disappears, it is directly transmitted to the control unit through an electrical signal. A shielding baffle can be arranged on one side of the electromagnetic induction sensor 425, so that when the electromagnetic induction sensor 425 passes through the metal wire 92, the detection signal is blocked, triggering the first electric push rod 412 to stop immediately; the optical time domain reflectometer 426 (OTDR) collects the data of the optical fiber 91 through the light-emitting diode, and transmits the measurement result to the data processing module through the communication interface. After the data processing module analyzes and calculates the relative distance between the optical fiber 91 and the metal wire 92, it feeds back the calibration parameters to the control unit; the control unit combines the direct shutdown instruction of the electromagnetic induction sensor 425 and the optical fiber 91 status data of the OTDR to form a double insurance mechanism, dynamically controls the action of the electric push rod, ensures the safe cooperation of the metal wire 92 and the optical fiber 91 during the peeling and fusion process, and finally realizes the efficient and accurate connection of the composite cable 9.

[0224] In the above embodiments, when the spot welding assembly 62 needs to be driven to rotate around the wire 92, the second motor 618 is started, so that the second motor 618 drives the second driving gear 617 to rotate. Subsequently, the rotation of the second driving gear 617 drives the second arc-shaped rack 616 engaged with it to rotate around the central axis of the C-shaped mounting plate 612, so that the second arc-shaped rack 616 drives the C-shaped mounting plate 612 to rotate. The openings of the C-shaped mounting plate 612, the C-shaped limiting plate 614, the C-shaped sliding plate 613, and the C-shaped baffle 615 are for the composite cable 9 to enter the rotation driving assembly 61.

During the winding process, the C-shaped mounting plate 612 drives the PVC film 86 to continuously wind around the surface of the metal wire 92.
[0238] Please refer to Figures 1-9 , the exemplary embodiment of the present disclosure also provides a wiring method, including the following steps:
[0239] S1. Pretreat the butt-end cable: Manually level the butt-end interfaces of the two composite cables 9 and cut the skin of the exposed part of the metal wire 92.
[0240] S2. Core alignment and calibration: Install the pretreated composite cables 9 into the core-twisting mechanisms 1 arranged symmetrically respectively, and synchronously rotate the two groups of composite cables 9 through the twisting drive assembly 3 to axially align the internal metal wires 92 and optical fibers 91 respectively.
[0241] S3. Metal wire 92 stripping and positioning: Drive the first telescopic mechanism 41 of the two groups of metal wire stripping structures 4 to feed obliquely towards the composite cable 9, and use the electromagnetic induction sensor 425 on the stripping block 42 to detect the position of the metal wire 92. When the sensor parameter changes from increasing to decreasing, it is determined that the edge of the metal wire 92 is contacted.
[0242] S4. Optical fiber 91 exposure control: Based on the optical time domain reflectometer 426 to detect the position data of the optical fiber 91, dynamically adjust the stroke of the first telescopic mechanism 41 through the control unit, so that the two side stripping blocks 42 push the metal wire 92 outwards to a predetermined distance, completely exposing the middle optical fiber 91.
[0243] S5. Optical fiber 91 fusion and detection: Manipulate the fusion splicer mounting arm 7 to move the optical fiber fusion splicer to the butt joint position for fusion splicing. After fusion splicing is completed, scan and detect the fusion splicing integrity along the axial direction of the optical fiber 91 through the optical time domain reflectometer 426.
[0244] S6. Reset welding of the metal wire 92: After confirming that the fusion splicing of the optical fiber 91 is qualified, retract the stripping block 42 to make the metal wire 92 reset and contact, and drive the rotary spot welding mechanism 6 to continuously spot weld and fix around the metal wire 92 along the arc-shaped servo slide rail 5.
[0245] In the above embodiment, manually cut off the exposed skin of the metal wire 92 at the butt end of the composite cable 9 and level the end face to ensure that the end structures of the two composite cables 9 are the same. Install the pre-treated cables on the core-aligning torsion mechanisms 1 arranged symmetrically respectively. Synchronously rotate the two groups of composite cables 9 through the torsion drive assembly 3 to automatically axially align the internal metal wire 92 and the optical fiber 91, eliminate the connection deviation caused by the torsion or offset of the wire core. Drive the first telescopic mechanism 41 of the metal wire stripping structure 4 to push the stripping block 42 to feed towards the composite cable 9 at an inclined angle. Real-time detect the contact state of the metal wire 92 through the electromagnetic induction sensor 425 integrated in the stripping block 42. When the sensor parameter suddenly changes from increasing to decreasing, it is determined that the stripping block 42 contacts the edge of the metal wire 92. Combine the axial position data of the optical fiber 91 detected by the optical time domain reflectometer 426 (OTDR). The control unit dynamically adjusts the stroke of the first telescopic mechanism 41 to precisely push the metal wire 92 by the two side stripping blocks 42 to a preset distance, completely expose the middle optical fiber 91 and avoid damage. Move the optical fiber fusion splicer to the exposed position through the fusion splicer mounting arm 7 to complete the fusion splicing. The OTDR scans the reflection loss value of the fusion splice point along the axial direction of the optical fiber 91 to determine the fusion splicing integrity. After the fusion splicing is qualified, retract the stripping block 42, the metal wire 92 resets and fits. Drive the rotary spot welding mechanism 6 to slide circumferentially around the composite cable 9 along the arc-shaped servo slide rail 5 for continuous spot welding and fixing.
