Description

Technical Field

[0001] This invention relates to the technical field of communication testing equipment, and in particular to a line fault detection device for communication engineering and its cable rewinding structure. Background Technology

[0002] During the construction of communication projects, a large number of pipelines are laid for remote data transmission. In order to ensure the quality of communication, routine maintenance and upkeep of the lines are required, and regular fault detection of the lines is necessary. There are some line fault detection instruments that pull out the detection wires inside the instrument, clamp the circuit clips onto the section of the line to be tested, and then judge the fault of the line by the power-on status of the fault detection instrument.

[0003] To avoid directly storing the test leads inside the casing of fault detection instruments, the test leads are wound up using a cable reel before being stored inside the instrument. However, to prevent tangling at the connection point between the test lead and the instrument during winding and unwinding, the connection point is often inserted into the instrument only after the winding and unwinding process is complete, which is inconvenient. In some existing technologies, a movable connector is used at the connection point to prevent tangling; however, at high winding speeds, tangling can still occur at the movable connector, affecting the normal winding and unwinding of the test lead. Summary of the Invention

[0004] Therefore, it is necessary to provide a line fault detection device for communication engineering and its cable rewinding structure to solve the problem that the cable rewinding structure of fault detection instruments is not convenient to use.

[0005] To achieve the above objectives, the inventors provide a cable rewinding structure for communication engineering, comprising:

[0006] case,

[0007] The roller is rotatably connected to the housing.

[0008] A cable is wound onto a roller; one end of the cable is equipped with a detection part, and the other end of the cable is equipped with a connecting part.

[0009] An energized ring is fitted onto and connected to the roller.

[0010] An energized slider has one end slidably connected to an energized ring, and the other end is used to connect to a fault detector. The energized slider is electrically connected to the connection part of the cable through the energized ring.

[0011] Furthermore, there are two rollers, each used to wind up one cable, and the fault detector, the two cables, and the circuit to be tested form a current loop.

[0012] Furthermore, the side of the housing is provided with an opening, and a sliding door is longitudinally slidably provided at the opening of the housing. The bottom of the sliding door is provided with a cable passage groove for the cable to pass through, and the number of the cable passage grooves corresponds to the number of cables.

[0013] Furthermore, a limiting component is provided at the opening of the housing, and a limiting hole is provided on the sliding door. The limiting component is used to adapt to the limiting hole so that the sliding door and the opening are in a semi-closed state.

[0014] Furthermore, the limiting component includes a sliding plate and a rod. The sliding plate is vertically disposed at the opening of the housing, and the rod is movably connected to the sliding plate and can be inserted into the limiting hole.

[0015] Furthermore, the limiting components are symmetrically arranged on both sides of the sliding door.

[0016] Furthermore, the energized slider includes a connected slider body and a connecting pipe. The energized ring is provided with an energized groove along its circumference. The slider body is adapted to the energized groove and slides along the energized groove. The connecting pipe is used to electrically connect the slider body to the fault detector.

[0017] Furthermore, the cable connection portion is provided with a cable fixing portion, which is fixed to the roller, and the cable fixing portion is electrically connected to the energized ring through a circuit connection.

[0018] Furthermore, the detection section of the cable is equipped with an electrical clamp.

[0019] The inventors also provide a line fault detection device for communication engineering, comprising: a fault detector and a cable winding structure for communication engineering as described in any of the above technical solutions, wherein the fault detector is mounted on the housing.

[0020] Unlike existing technologies, the above-mentioned technical solution has the following advantages: When using this cable reel structure for communication engineering, the cable connector is released from the drum. Rotating the drum allows for a longer cable length to be released, and the connector is then inserted into the line to be tested. During the drum's rotation, the energizing ring rotates accordingly, and the cable connector also rotates on the drum. Throughout this rotation, the connector is electrically connected to the energizing slider via the energizing ring, thus establishing a connection with the fault detector. This allows the fault detector to test the line to be tested. During the drum's rotation and reeling process, the cable connector remains fixed on the drum and connected to the fault detector via the energizing ring and slider. The relative position between the cable connector and the drum remains stable, and the cable reeling always occurs on the drum. The cable connector does not bend, twist, or coil, making it convenient and quick to use. Attached Figure Description

[0037] Please see Figures 1 to 2 This embodiment provides a fault detection device for communication engineering lines, including: a fault detector 12 and a cable reel structure for communication engineering 5. The fault detector 12 is mounted on a housing 1. The specific structure of the cable reel structure for communication engineering 5 is detailed in the following specific embodiment. The fault detector 12 is a commonly available instrument for communication line testing. The cable reel structure for communication engineering 5 includes a housing 1. The fault detector 12 can be directly installed inside or outside the housing 1, and is electrically connected to the cable 5 wound in the cable reel structure. The cable 5 wound in the cable reel structure can be pulled out from the housing 1 and connected to the line to be tested, forming a current loop with the fault detector 12, the cable 5, and the line to be tested, thereby enabling the testing of the line.

[0038] Please see Figure 1 , Figure 3 as well as Figure 5 This embodiment provides a 5-reel structure for communication engineering cables, including:

[0039] Casing 1,

[0040] Roller 3 is rotatably connected to housing 1.

[0041] Cable 5 is wound onto roller 3. One end of cable 5 is provided with a detection part, and the other end of cable 5 is provided with a connecting part.

[0042] The energized ring 9 is sleeved on and connected to the roller 3.

[0043] The energized slider has one end slidably connected to the energized ring 9, and the other end is used to connect to the fault detector 12. The energized slider is electrically connected to the connection part of the cable 5 through the energized ring 9.

[0044] The housing 1 is used to protect and support the roller 3 and other structures. The roller 3 can be installed laterally or longitudinally inside the housing 1. To reduce the longitudinal height of the cable 5 winding structure for communication engineering, the roller 3 is usually installed laterally inside the housing 1. Support shafts 4 are provided at both ends of the roller 3. Support shaft 4 connection holes are provided on both sides of the housing 1 for inserting the support shafts 4. The support shafts 4 are connected to the support shaft 4 connection holes via bearings, allowing the support shafts 4 of the roller 3 to rotate around the support shaft 4 connection holes via bearings. The connecting part of the cable 5 is wound onto the roller 3 first, and the detection part of the cable 5 can be unwound from the roller 3. As the roller 3 rotates, the detection part of the cable 5 can be pulled out a certain length from the roller 3 for connection to the line to be tested. To achieve a detection loop for the line to be tested, two cables 5 are used. The two cables 5 can be wound onto the same roller 3 simultaneously, and the detection parts of the two cables 5 are respectively connected to the two ends of the line to be tested. The energized ring 9 can be sleeved and fixed to the end of the roller 3, or it can be sleeved and fixed to the middle of the roller 3. The energized ring 9 is made of conductive material. During the sliding process of the energized slider on the energized ring 9, the energized slider will not detach from the energized ring 9. Specifically, the energized slider is always located on the rotation trajectory of the energized ring 9, or the energized slider and the energized ring 9 are connected by an anti-detachment buckle structure, an anti-detachment slide structure, or other structures that can prevent the two from detaching. Of course, since the energized slider needs to be connected to the fault detector 12, it is necessary to keep the energized slider and the fault detector 12 relatively stationary as much as possible. The energized slider can be fixed, specifically, it can be fixedly connected to the housing 1, and the energized slider is vertically set on the energized ring 9. In this case, it is only necessary for the energized slider and the energized ring 9 to be compatible.

[0045] In use, the cable 5 winding structure for this communication engineering project involves releasing the connector of cable 5 from the drum 3. Rotating the drum 3 extends the cable 5 to a longer length, allowing the connector to be inserted into the line to be tested. During the rotation of the drum 3, the energizing ring 9 rotates accordingly, and the connector of cable 5 also rotates on the drum 3. Throughout this rotation, the connector is electrically connected to the energizing slider via the energizing ring 9, thus connecting to the fault detector 12. The fault detector 12 can then be used to test the line to be tested. During the winding and unwinding rotation of the drum 3, the connector of cable 5 remains fixed on the drum 3 and connected to the fault detector 12 via the energizing ring 9 and the energizing slider. The relative position between the connector of cable 5 and the drum 3 remains stable, and the winding of cable 5 always occurs on the drum 3. The connector of cable 5 does not bend, twist, or coil, making it convenient and quick to use.

[0046] In some preferred embodiments, there are two rollers 3, each used to wind up two cables 5. The fault detector 12, the two cables 5, and the circuit to be tested form a current loop. A partition 2 can be provided inside the housing 1, and the two rollers 3 are rotatably mounted on both sides of the partition 2. The two rollers 3 are also rotatably connected to the housing 1, allowing the two rollers 3 to rotate independently. Each roller 3 is used to wind up one cable 5, enabling independent winding and unwinding of the two cables 5. This reduces the circumferential dimension of the rollers after winding up the cables 5 and further prevents the two cables 5 from getting tangled together, improving ease of use.

[0047] like Figure 1 , Figure 6 As shown, in some preferred embodiments, the side of the housing 1 is provided with an opening, and a sliding door 20 is longitudinally slidably provided at the opening of the housing 1. The bottom of the sliding door 20 is provided with a wiring groove 21 for the cable 5 to pass through, and the number of wiring grooves 21 corresponds to the number of cables 5. The horizontally placed roller 3, on which the cable 5 is wound, can extend from the side opening of the housing 1 to the outside of the housing 1. The sliding door 20 helps to separate the internal and external spaces of the housing 1, protects the roller 3 and other structures placed inside the housing 1, and also prevents electric shock caused by misoperation during the testing process. After the cable 5 is connected to the circuit to be tested, the sliding door 20 can be closed, allowing the cable 5 to be placed in the wiring groove 21.

[0048] In some more preferred embodiments, a limiting component is provided at the opening of the housing 1, and a limiting hole is provided on the sliding door 20. The limiting component is used to fit with the limiting hole so that the sliding door 20 and the opening are in a semi-closed state. When the limiting component fits with the limiting hole, there is still a certain gap between the sliding door 20 and the bottom of the opening, and there is also a certain gap between the cable 5 wound on the roller 3 and the bottom of the housing 1. The limiting component, which keeps the sliding door 20 in a semi-closed state, allows the cable 5 to still be smoothly pulled out from the bottom of the sliding door 20, and also isolates the inner and outer spaces of the housing 1, protecting the roller 3 and other structures placed inside the housing 1, and preventing electric shock caused by misoperation during the testing process.

[0049] In some more preferred embodiments, the limiting component includes a sliding plate 19 and a rod 25. The sliding plate 19 is vertically disposed at the opening of the housing 1, and the rod 25 is movably connected to the sliding plate 19 and can be inserted into the limiting hole. The sliding plate 19 is adapted to the thickness of the sliding door 20 and is fixedly disposed on the housing 1. The sliding plate 19 provides a sliding track for the sliding door 20. The connection between the rod 25 and the sliding plate 19 can be that the rod passes through a slot in the sliding plate 19 or is installed on the sliding plate 19 through other accessories. After the winding process is completed, the limiting component separates from the limiting hole, allowing the cable 5 to be placed in the cable through groove 21.

[0050] In some more preferred embodiments, the limiting components are symmetrically arranged on both sides of the sliding door 20. This has the advantage of making the sliding door 20 slide more smoothly and efficiently.

[0051] In some preferred embodiments, the energized slider includes a connected slider body 10 and a connecting tube 11. The energized ring 9 has an energized groove along its circumference. The slider body 10 is adapted to the energized groove and slides along it. The connecting tube 11 is used to electrically connect the slider body 10 to the fault detector 12. The slider body 10 is made of a conductive material, and the connecting tube 11 can also be made of a conductive material or have wires threaded inside for conducting electricity between the slider body 10 and the fault detector 12. The extension direction of the energized groove is the same as the rotation direction of the roller 3. The slider body 10 and the connecting tube 11 are fixedly disposed relative to the housing 1. The slider body 10 can be connected to the housing 1 through the connecting tube 11. During the rotation of the roller 3, the slider body 10 moves along the energized groove of the roller 3, maintaining the continuity between the cable 5 and the fault detector 12 at all times.

[0052] In some preferred embodiments, the connecting portion of the cable 5 is provided with a cable fixing part 6, which is fixed to the roller 3. The cable fixing part 6 is electrically connected to the energized ring 9 via a circuit connection 7. The cable fixing part 6 secures the cable 5 to the roller 3 and provides an electrical connection between the cable 5 and the energized ring 9, improving the structural stability of the cable winding structure for communication engineering. Furthermore, when the cable 5 needs to be replaced, it is only necessary to fix the connecting portion of the new cable 5 to the cable fixing part 6, facilitating cable replacement.

[0053] In some preferred embodiments, the detection section of the cable 5 is provided with an electrical clamp 14. The electrical clamp 14 allows the detection section of the cable 5 to quickly make an electrical connection with the circuit under test, improving detection efficiency.

[0054] The inventors also provided the following specific embodiments:

[0055] Example 1:

[0056] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5 This invention provides a technical solution including a housing 1, with a partition 2 fixedly connected to the center of the inner wall of the housing 1. A cable winding structure for communication engineering is provided inside the housing 1. The cable winding structure includes a roller 3, with a support shaft 4 fixedly connected through the center of both sides of the roller 3. One side of the support shaft 4 is rotatably connected to the side of the partition 2 via a bearing, and the other side of the support shaft 4 is rotatably connected to the side wall of the housing 1 and fixedly connected to a turntable 13. The turntable 13 is located outside the housing 1. A cable 5 is wound around the surface of the roller 3. One end of the cable 5 is fixedly connected to a cable fixing part 6. A circuit connection 7 is fixedly connected to the side of the cable fixing part 6 away from the cable 5. A fixing ring 8 is fixedly sleeved on one side of the surface of the roller 3. A current-carrying ring 9 is fixedly sleeved on the outer side of the fixing ring 8. A current-carrying groove is formed on the outer side of the current-carrying ring 9. The end of the circuit connection 7 away from the cable fixing part 6 is fixedly connected to... The outer wall of the energized ring 9 is connected to the upper end of the inner wall of the energized groove of the energized ring 9, and the upper end of the slider body 10 is fixedly connected to the upper end of the slider body 10. The end of the cable 5 away from the cable fixing part 6 is fixedly connected to the electrical clamp 14. The upper surface of the housing 1 is fixedly connected to the fault detector 12. The upper end of the connecting tube 11 passes through and is fixedly connected to the upper side wall of the housing 1 and is fixedly connected to the fault detector 12. The upper surface of the housing 1 is fixedly connected to the protective shell 15. The upper surface of the protective shell 15 has a through groove and a glass plate is installed on the inner wall of the through groove. The opening of the protective shell 15 is fixedly connected to the fixing groove plate 18. The inner wall of the fixing groove plate 18 is slidably connected to the baffle 16. The side of the baffle 16 is fixedly connected to the first handle 17. The opening on the side of the housing 1 away from the sliding groove plate 19 is fixedly connected to the side baffle 29 by a screw. The upper surface of the housing 1 is fixedly connected to the second handle 28 on both sides.

[0057] In this embodiment: pulling the electrical clamp 14 pulls the cable 5 off the roller 3. The roller 3 is supported by the support shaft 4. The end of the cable 5 away from the electrical clamp 14 is connected to the cable fixing part 6, maintaining the wire connection. Then, the cable fixing part 6 is electrically connected to the energized ring 9 through the circuit wiring 7. When the roller 3 rotates, the cable fixing part 6, the circuit wiring 7, and the energized ring 9 all rotate accordingly. The slider body 10 slides along the inner wall of the energized groove of the energized ring 9 to maintain the electrical connection. Then, the circuit connection wire in the connecting tube 11 is connected to the fault detector 12 above, so that when the roller 3 rotates, the electrical clamp 14 and the fault detector 12 can maintain an electrical connection. The electrical clamp 14 is clamped on both sides of the line to be tested and the line is energized. At this time, the fault detector 12 establishes an electrical connection with the line to be tested and forms a circuit. The fault detector 12 is used to determine whether the circuit is working properly. When it is necessary to adjust the parameters and working mode of the fault detector 12, the handle 17 can be pulled to slide the baffle 16 to open the protective shell 15 and operate the internal fault detector 12. The glass plate of the protective shell 15 makes it easy to see the display numbers of the fault detector 12. The operation is quick and portable. After the test is completed, the power to the circuit is turned off and the electrical clamp 14 is removed. Then, the turntables 13 on both sides are rotated to rewind the cable 5 back onto the roller 3, keeping the cable 5 wrapped around the roller 3. This makes the circuit neater and avoids mess, and also improves the speed of storage and retrieval. It solves the technical problems that require sorting when pulling out and storing the cable, which is cumbersome and not fast enough. The tangled cable can easily cause bending and damage to the cable itself, making it not portable and reliable.

[0058] Example 2:

[0059] Please see Figure 1 , Figure 4 and Figure 6 Based on Embodiment 1, the present invention provides a technical solution: Slide plates 19 are fixedly connected to both ends of the side opening of the housing 1; a sliding door 20 is slidably connected to the inner wall of the slide plate 19; a top plate 22 is fixedly connected to the upper end of the sliding door 20; a connecting block 23 is fixedly connected to the outer wall of the slide plate 19; a vertical plate 24 is fixedly connected to the end of the connecting block 23 away from the slide plate 19; a rod 25 is slidably connected through the middle of the vertical plate 24; and a side plate 25 is fixedly connected to one end of the rod 25. The surface of the cover 26 and the insert rod 25 is fixedly fitted with a limiting ring 27. The vertical plate 24 is located between the side cover 26 and the limiting ring 27. The surface of the insert rod 25 passes through the surface of the sliding connection slide plate 19. The surface of the sliding door 20 is provided with a card hole on both sides. The end of the insert rod 25 away from the side cover 26 is slidably connected to the inner wall of the card hole of the sliding door 20. The lower two ends of the surface of the sliding door 20 are provided with a wire through groove 21. The end of the cable 5 away from the cable fixing part 6 passes through the inner wall of the wire through groove 21.

[0060] In this embodiment: Pulling up the top plate 22 causes the sliding door 20 to slide upwards, thereby opening one side of the housing 1 for easy access to the electrical clamp 14. After pulling out the electrical clamp 14, the cable 5 is placed in the cable channel 21. The sliding door 20 is then pushed down, and the side cover 26 is gently pushed to move the insertion rod 25 towards the slide plate 19, causing the end of the insertion rod 25 to slide against the surface of the sliding door 20. As the sliding door 20 moves downwards, the end of the insertion rod 25 engages in the locking hole of the sliding door 20. At this time, the sliding door 20 has not completely fallen, and the cable... The cable channel 21 is located at the lower edge of the side opening of the housing 1. At this time, the cable 5 can be pulled out through the cable channel 21. During the test, it prevents foreign objects from entering the housing 1, protects the wiring inside the housing 1, and prevents accidental electric shock caused by touching the energizing ring 9, thus improving safety. After the test is completed, the plug rod 25 is pulled out so that the sliding door 20 slides down completely to close the opening of the housing 1. The side cover 26 and the limiting ring 27 play a limiting role to prevent the plug rod 25 from detaching from the vertical plate 24 and to prevent loss.

[0061] Working principle: Carry the device to the work area using the handle 28. Place the device on one side of the line to be tested, then pull up the top plate 22 to slide the sliding door 20 upwards, thus opening one side of the housing 1. After pulling out the electrical clamp 14, place the cable 5 in the line through groove 21. Push the sliding door 20 down and gently push the side cover 26 to move the insertion rod 25 towards the slide plate 19, so that the end of the insertion rod 25 slides against the surface of the sliding door 20. As the sliding door 20 moves down, the end of the insertion rod 25 gets into the locking hole of the sliding door 20. At this time, the sliding door 20 is not completely lowered, and the line through groove... 21 is located at the lower edge of the side opening of the housing 1. At this time, the cable 5 can be pulled out through the cable ... The electrical connection forms a circuit, and the fault detector 12 can be used to determine whether the circuit is working properly. When it is necessary to adjust the parameters and working mode of the fault detector 12, the handle 17 can be pulled to slide the baffle 16 to open the protective shell 15 and operate the internal fault detector 12. The glass plate of the protective shell 15 makes it easy to view the display numbers of the fault detector 12. The operation is quick and portable. After the test is completed, the power to the circuit is turned off and the electrical clamp 14 is removed. Then, the turntables 13 on both sides are rotated to rewind the cable 5 back onto the roller 3, keeping the cable 5 wound on the roller 3 for a more neat and tidy state. To avoid clutter, when the cable 5 is pulled out for testing, the position and angle of the cable 5 located between the cable channel 21 and the roller 3 can be kept fixed. When the cable 5 is pulled back, it can be wound onto the roller 3 in sequence, avoiding the cable 5 from getting tangled and making it easy to manage. In conjunction with the winding device, the winding efficiency is further improved. When it is necessary to maintain the internal structure of the housing 1 in the future, the sliding door 20 can be slid up to open one side opening of the housing 1, and the screw on the side baffle 29 can be unscrewed to open the other side opening, thereby facilitating the maintenance and inspection of the inside of the housing 1.

[0062] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
