Description

Technical Field

[0001] This utility model relates to the technical field of integrated prefabricated cable accessories, and more specifically, it relates to an integrated prefabricated cable accessory. Background Technology

[0002] In power systems, cable accessories are a key component in ensuring the safe and reliable operation of cable lines. However, existing cable accessories still have some problems in protecting cable joints.

[0003] Firstly, existing technologies mostly protect the cable by using a corrugated sleeve on the outside of the cable connection. The corrugated sleeve is designed to alleviate the stress that the cable may encounter during operation and ensure the safety of the cable connection. However, the expansion and contraction length of the corrugated sleeve is usually inconvenient to control according to the usage requirements, which may lead to greater stress at the cable connection and affect the safe operation of the cable.

[0004] Secondly, the installation and removal of corrugated sleeves responsible for protecting the connection in existing technologies are usually quite cumbersome. This is mainly because the corrugated sleeve needs to be precisely fitted onto the cable connection. Such precise installation and removal requires professional personnel and tools, and cannot be done quickly. This brings inconvenience to cable maintenance and replacement, especially in emergency situations, where rapid maintenance cannot be achieved, thus having an adverse effect.

[0005] In addition, to address the aforementioned issues, existing technologies employ various devices for the rapid installation and removal of corrugated sleeves. However, these devices are relatively simple in structure, resulting in low stability of the installation structure. During prolonged use, these devices are prone to loosening or even detachment, thereby affecting the safety of cable connections. Such loosening or detachment may lead to cable faults and threaten the stable operation of the power system. Utility Model Content

[0031] Please see Figure 1-5 An integral prefabricated cable accessory 1 includes a cable 1, characterized in that: an installation device is installed on the outside of the cable 1, and a connecting device is provided on the outside of the cable 1. The connecting device includes a connecting sleeve 2, a release sleeve 3, a push spring 4, a push plate 5, a plug-in mechanism, a connecting rod 6, a diameter reducing plate 7, a connecting rod 8, and a diameter reducing groove 9. The connecting sleeve 2 is detachably sleeved on the outside of the connecting rod 6, the release sleeve 3 is movably sleeved on the outside of the connecting sleeve 2, the push plate 5 is connected to the inside of the connecting sleeve 2 through the push spring 4, the diameter reducing plate 7 is slidably disposed in the diameter reducing groove 9, the connecting rod 8 is fixedly connected to one side of the diameter reducing plate 7, the diameter reducing groove 9 is opened in the release sleeve 3, and a mating mechanism is provided on the outside of the connecting sleeve 2. The mating mechanism includes a mating sleeve 10, a spring 11, an adapter rod 12, and an adapter groove 13. The mating sleeve 10 is movably sleeved on the outside of the connecting sleeve 2 through threads, the adapter rod 12 is movably connected to the outside of the release sleeve 3 through the spring 11, and the adapter groove 13 is opened on the outside of the connecting sleeve 2.

[0032] Both the connecting sleeve 2 and the connecting rod 6 have a pressing plate 14 at one end.

[0033] The insertion mechanism includes a plug rod 15 and a slot 16. The plug rod 15 is fixedly connected to one end of the connecting rod 8 and is inserted into the slot 16, which is located on the outside of the connecting rod 6.

[0034] The outer side of the fitting sleeve 10 is provided with anti-slip strips 17, and multiple anti-slip strips 17 are fixedly connected to the outer side of the fitting sleeve 10.

[0035] In this embodiment, when it is necessary to connect the connecting plate 20 and the fixing plate 19 together, firstly, the holes on the connecting plate 20 and the fixing plate 19 are aligned. Then, the connecting rod 6 passes through the fixing plate 19 and the connecting plate 20 from one side of the fixing plate 19. Then, the connecting sleeve 2 is fitted onto the outside of the connecting rod 6 from one side of the connecting plate 20, so that the connecting rod 6 pushes the push plate 5 to compress the push spring 4. Then, the release sleeve 3 is rotated, and the release sleeve 3 will drive the adapter rod 12 to move. Due to the rounded corner structure design at the edges of the adapter rod 12 and the adapter groove 13, and the fact that the spring 11 only provides a small force, the side wall of the adapter groove 13 will compress the side wall of the adapter rod 12, so that one end of the adapter rod 12 slides out of the adapter groove 13. At the same time, the other end of the adapter rod 12 will stretch the spring 11. Meanwhile, the release sleeve 3 will drive the variable diameter groove 9 to move. Due to the special... The structural design involves the variable diameter plate 7 being driven by the connecting rod 8 to gradually insert the insertion rod 15 into the slot 16. At this time, the pressing plate 14 on one side of the connecting sleeve 2 and the pressing plate 14 on the other side of the connecting rod 6 cooperate to press the fixing plate 19 and the connecting plate 20 together. Simultaneously, the adapter rod 12 moves to the position corresponding to the other adapter slot 13. Then, the spring 11 drives the adapter rod 12 to reset and inserts the other end of the adapter rod 12 into the adapter slot 13. Then, the two mating sleeves 10 are rotated respectively, and the mating sleeves 10 slide spirally along the threaded line on the outside of the connecting sleeve 2. The inner wall of the mating sleeve 10 limits the outer side of the adapter rod 12, thereby preventing the adapter rod 12 from moving. Then, the adapter rod 12 and the adapter slot 13 cooperate to limit the release sleeve 3, thereby preventing the release sleeve 3 from rotating and ensuring the stability of the installation structure.

[0036] Please see Figure 1 As one embodiment of the installation device: the installation device includes an insulating sleeve 18, a fixing plate 19, a connecting plate 20 and a corrugated sleeve 21. The insulating sleeve 18 is fitted on the outside of the cable 1. The fixing plate 19 is fixedly connected to the outside of the insulating sleeve 18 at two locations. The connecting plate 20 is connected to both sides of the corrugated sleeve 21. The corrugated sleeve 21 is fitted on the outside of the insulating sleeve 18.

[0037] A sliding plate 22 is provided on the outer side of the connecting plate 20, and a screw 23 is provided on the inner side of the sliding plate 22. The screw 23 is slidably disposed on the inner side of the sliding plate 22.

[0038] A screw sleeve 24 is provided on one side of the sliding plate 22, and the screw sleeve 24 is movably connected to the screw rod 23 by threads.

[0039] A knob 25 is provided on one side of the sliding plate 22, and the knob 25 is fixedly connected to one end of the screw 23.

[0040] More specifically, when using this equipment, firstly, the insulating sleeve 18 with the fixing plate 19 is fitted onto the outside of the two cables 1 respectively. Then, the corrugated sleeve 21 is fitted onto the outside of the insulating sleeve 18. Then, the corrugated sleeve is manually tightened. Then, the two cables 1 are connected. After the two cables 1 are connected, the corrugated sleeve 21 is loosened, allowing the corrugated sleeve 21 to extend and return to its original position. Then, when the two connecting plates 20 respectively abut against the fixing plate 19 fitted onto the outside of the insulating sleeve 18, the knob 25 is rotated. The knob 25 drives the screw 23 to rotate. Since the screw sleeve 24 and the screw 23 are movably connected by threads, the screw sleeve 24 will slide spirally along the screw 23. When the knob 25 and the screw sleeve 24 are close to one side of the two sliding plates 22 respectively, the knob 25 and the screw sleeve 24 limit the sliding plate 22, thereby limiting the fixing plate 19. This restricts the extension and retraction length of the corrugated sleeve 21, thus preventing the cable 1 connection from being subjected to excessive stress and breaking.

[0041] In summary, during the use or operation of the overall equipment: when it is necessary to connect the connecting plate 20 and the fixing plate 19 together, first align the holes on the connecting plate 20 and the fixing plate 19, then pass the connecting rod 6 through the fixing plate 19 and the connecting plate 20 from one side of the fixing plate 19, and then fit the connecting sleeve 2 onto the outside of the connecting rod 6 from one side of the connecting plate 20, so that the connecting rod 6 pushes the push plate 5 to compress the push spring 4. Then rotate the release sleeve 3, which will drive the adapter rod 12 to move. Due to the rounded corner design of the adapter rod 12 and the adapter groove 13, and the fact that the spring 11 only provides a small force, the side wall of the adapter groove 13 will compress the side wall of the adapter rod 12, causing one end of the adapter rod 12 to slide out of the adapter groove 13. At the same time, the other end of the adapter rod 12 will stretch the spring 11. Meanwhile, the release sleeve 3 will drive the variable diameter groove 9 to move. With the special structural design of 7, the variable diameter plate 7 will drive the insertion rod 15 to gradually insert into the slot 16 through the connecting rod 8. At this time, the pressing plate 14 on one side of the connecting sleeve 2 and the pressing plate 14 on the one side of the connecting rod 6 cooperate to press the fixing plate 19 and the connecting plate 20. At the same time, the adapter rod 12 moves to the position corresponding to the other adapter groove 13. Then the spring 11 drives the adapter rod 12 to reset and inserts the other end of the adapter rod 12 into the adapter groove 13. Then, the two mating sleeves 10 are rotated respectively. The mating sleeves 10 will slide spirally along the thread line on the outside of the connecting sleeve 2. Then the inner wall of the mating sleeve 10 will limit the outside of the adapter rod 12, thereby preventing the adapter rod 12 from moving. Then the adapter rod 12 and the adapter groove 13 cooperate to limit the release sleeve 3, thereby preventing the release sleeve 3 from rotating, thus ensuring the stability of the installation structure.

[0042] When using this device, first, the insulating sleeve 18 with the fixing plate 19 is fitted onto the outside of the two cables 1 respectively. Then, the corrugated sleeve 21 is fitted onto the outside of the insulating sleeve 18. The corrugated sleeve is then manually tightened. The two cables 1 are then connected. After the two cables 1 are connected, the corrugated sleeve 21 is loosened, allowing it to extend and return to its original position. Then, when the two connecting plates 20 abut against the fixing plate 19 fitted onto the outside of the insulating sleeve 18, the knob 25 is rotated. The knob 25 drives the screw 23 to rotate. Since the screw sleeve 24 and the screw 23 are movably connected by threads, the screw sleeve 24 will slide spirally along the screw 23. When the knob 25 and the screw sleeve 24 are close to one side of the two sliding plates 22 respectively, the knob 25 and the screw sleeve 24 limit the sliding plate 22, thereby limiting the fixing plate 19. This restricts the extension and retraction length of the corrugated sleeve 21, thus preventing the cable 1 connection from being subjected to excessive stress and breaking.

For all the fixed connections mentioned above, welding is preferred.
