Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, and in particular to a reverse self-locking S-type anti-drop-out current-guiding connector for power line operation. Background Technology

[0002] 10kV lines, as a crucial component of power transmission, play a vital role in ensuring power supply, supporting economic and social development, and serving people's livelihoods. With increasing societal demands for power reliability, live-line working has gradually become a key means of resolving the conflict between line maintenance and power demand. However, due to geographical limitations, confined operating space, and non-standard installation of pole-mounted equipment, the application of conventional live-line working tools is significantly restricted. Currently, commonly used user lead wire splicing fittings in distribution network lines suffer from numerous defects such as high contact resistance and easy loosening, causing not only economic losses but also potentially serious personal safety hazards. Therefore, there is an urgent need to develop a new type of anti-loosening lead wire splicing clamp with anti-loosening function that can be installed live. Utility Model Content

[0003] In order to overcome the above-mentioned shortcomings of the prior art, this utility model provides a reverse self-locking S-type anti-drop-out current-guiding splicing clamp for power line operation.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a reverse self-locking S-type anti-drop-out current-guiding splice clamp for power line operation, including a housing, a lifting eye bolt, a pressure plate, a tightening bolt, a push plate, and an anti-drop-out device. The housing has a first clamping groove and a second clamping groove respectively opened at both ends. The lifting eye bolt is connected to the side wall of the first clamping groove of the housing. The pressure plate is set in the first clamping groove and connected to the lifting eye bolt. The tightening bolt is connected to the side wall of the second clamping groove of the housing. The push plate is set in the second clamping groove and connected to the tightening bolt. The anti-drop-out device passes through the bottom wall of the second clamping groove of the housing and abuts against and is fixed to the push plate.

[0005] As a further improvement of this utility model: the anti-drop device is threadedly connected to the bottom wall of the second wire clamping groove of the housing.

[0006] As a further improvement of this utility model: the anti-drop device includes a first tightening bolt and a second tightening bolt, the first tightening bolt and the second tightening bolt are respectively threaded to the bottom wall of the second wire clamping groove of the housing, and the first tightening bolt and the second tightening bolt are staggered along the axis of the tightening bolt.

[0007] As a further improvement of this utility model: the second clamping groove includes a second semi-circular groove and an elongated wire groove that are interconnected. The push plate is slidably disposed within the elongated wire groove. The tightening bolt passes through the side wall of the elongated wire groove of the housing and connects to the push plate. The first tightening bolt and the second tightening bolt are respectively threadedly connected to the bottom wall of the elongated wire groove of the housing. The distance between the first tightening bolt and the side wall of the elongated wire groove is less than the distance between the second tightening bolt and the side wall of the elongated wire groove. By providing an elongated wire groove and having the push plate slidably disposed within it, the elongated wire groove limits and guides the sliding direction of the push plate, making the clamping of the wire more reliable when the push plate clamps it.

[0008] As a further improvement of this utility model: the push plate is a Y-shaped push plate, which is slidably disposed within the elongated wire groove. By using a Y-shaped push plate and slidably disposed within the elongated wire groove, the cooperation between the Y-shaped push plate and the elongated wire groove further improves the reliability of the clamping.

[0009] As a further improvement of this utility model: the tightening bolt is threadedly connected to the side wall of the elongated wire groove of the housing. By connecting the tightening bolt to the side wall of the elongated wire groove, the displacement of the push plate can be precisely adjusted, and the pushing force can be stably transmitted to the push plate to evenly press the wire, which has the advantage of convenient assembly and disassembly.

[0010] As a further improvement of this utility model: the push plate includes an integrally formed pushing part and a pressing part, the pushing part being matched with the elongated wire groove, and the pushing part being slidably disposed within the elongated wire groove. Because the push plate is provided with a pushing part that matches the elongated wire groove, when the push plate slides, the pushing part forms a guiding engagement with the inner wall of the elongated wire groove.

[0011] As a further improvement of this utility model: the tightening bolt is provided with an insertion part, and the push plate is provided with an insertion hole that matches the insertion part. The insertion part of the tightening bolt is inserted into the insertion hole of the push plate. Through the precise cooperation between the insertion part and the insertion hole, the pushing force of the tightening bolt is stably transmitted to the push plate, which pushes the push plate to move smoothly and evenly to press the wire.

[0012] As a further improvement of this utility model: the insertion part is a cylindrical insertion part, and the insertion hole is a cylindrical insertion hole that matches the cylindrical insertion part.

[0013] As a further improvement of this utility model: the first clamping groove includes a first semi-circular groove and a pressure plate mounting groove that are interconnected. The opening directions of the first semi-circular groove and the second semi-circular groove are opposite, and the first semi-circular groove and the second semi-circular groove form an S-shaped structure. By forming an S-shaped structure through the opposite opening directions of the first semi-circular groove and the second semi-circular groove, uniform clamping can be achieved in conjunction with the pressure plate and the push plate.

[0014] As a further improvement of this utility model: the lifting eye bolt is threadedly connected to the side wall of the first wire clamping groove of the housing. This threaded connection between the lifting eye bolt and the side wall of the first wire clamping groove facilitates pushing the pressure plate to tighten the wire.

[0015] As a further improvement of this utility model: a connecting groove is provided on one side of the pressure plate mounting groove of the housing, and a closing device is rotatably connected to the connecting groove. The closing device includes an integrally formed cylindrical connecting part and a square column closing part, and the cylindrical connecting part is rotatably connected to the connecting groove. By rotating the cylindrical connecting part to the connecting groove, the angle of the closing device can be flexibly adjusted.

[0016] As a further improvement of this utility model: the cylindrical connecting part is provided with a rotating groove, and a rotating rod is connected in the rotating groove. Both ends of the rotating rod are installed in the connecting groove, and a torsion spring is installed on the rotating rod. One end of the torsion spring is connected to the closing device, and the other end is connected to the housing. The torsion spring provides an automatic reset preload for the closing device. The cooperation between the rotating rod and the rotating groove ensures precise rotation. The two ends of the torsion spring are connected to the housing and the closing device respectively, allowing for continuous application of torque after installation to resist loosening caused by wire vibration and further prevent wire detachment.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model features a first wire clamping groove and a second wire clamping groove on both sides of the housing. A lifting eye bolt pushes a pressure plate in the first wire clamping groove forward to clamp the wire, and a tightening bolt pushes a push plate in the second wire clamping groove forward to clamp the wire, thus securing it firmly. The first and second wire clamping grooves are integrated, ensuring a reliable connection between the wires on both sides and effectively guaranteeing the integrity of the conductive path. An anti-drop device is provided, which passes through the bottom wall of the second wire clamping groove and abuts against the push plate. After the tightening bolt pushes the push plate in the second wire clamping groove forward to clamp the wire, tightening the anti-drop device further locks the push plate in place, preventing it from loosening.

[0019] 2. The reverse self-locking S-type anti-drop current-guiding connector for power line operation of this utility model can significantly reduce the labor intensity of operators and improve the safety of operation, providing strong support for building a clean, low-carbon, safe and reliable new power system.

[0020] 3. This utility model features a first and second tightening bolts offset along the axis of the tightening bolt. When the tightening bolt pushes the push plate in the second clamping groove forward to press the wire, the first and second tightening bolts on the anti-drop device are tightened sequentially to further fix the push plate. The first tightening bolt is tangential to the bottom of the push plate, forming a mechanical stop to resist the backward movement of the push plate caused by the tension of the wire, thus preventing the push plate from moving backward. The second tightening bolt abuts against the side of the push plate, generating tangential friction to further lock the position of the push plate and prevent it from loosening. The design of the first and second tightening bolts forms a double anti-loosening structure, and the double action creates a constant torque reverse self-locking effect, ensuring that the wire clamp will not loosen during long-term operation.

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. The present invention will now be further described in conjunction with the accompanying drawings and embodiments:

[0027] Please see Figure 1-4A reverse self-locking S-type anti-dropout current-guiding connector for power line operations includes a housing 1, a lifting eye bolt 2, a pressure plate 3, a tightening bolt 4, a push plate 5, and an anti-dropout device. The housing 1 has a first clamping groove 6 and a second clamping groove 7 at both ends. The lifting eye bolt 2 is connected to the right side wall of the first clamping groove 6 of the housing 1. The pressure plate 3 is disposed within the first clamping groove 6 and connected to the lifting eye bolt 2. The tightening bolt 4 is connected to the left side wall of the second clamping groove 7 of the housing 1. The push plate 5 is disposed within the second clamping groove 7 and connected to the tightening bolt 4. The anti-dropout device passes through the bottom wall of the second clamping groove 7 of the housing 1 and abuts against and is fixed to the push plate 5. The axial direction of the anti-dropout device is perpendicular to the axial direction of the tightening bolt 4.

[0028] The housing 1 has a first wire clamping groove 6 and a second wire clamping groove 7 on both sides. The lifting eye bolt 2 pushes the pressure plate 3 in the first wire clamping groove 6 forward to clamp the wire, and the tightening bolt 4 pushes the push plate 5 in the second wire clamping groove 7 forward to clamp the wire, thereby achieving the fastening of the wire. The first wire clamping groove 6 and the second wire clamping groove 7 are set as one piece, so that the wires on both sides can be reliably connected, which can effectively ensure the integrity of the conductive channel.

[0029] By providing an anti-drop device, which passes through the bottom wall of the second wire clamping groove 7 of the housing 1 and abuts against and is fixed to the push plate 5, when the tightening bolt 4 pushes the push plate 5 in the second wire clamping groove 7 to move forward and press the wire, the anti-drop device can be tightened to further lock the position of the push plate 5 and prevent the push plate 5 from loosening.

[0030] This utility model discloses a reverse self-locking S-type anti-drop-out current-guiding connector for power line operations, which can significantly reduce the labor intensity of operators, improve operational safety, and provide strong support for building a clean, low-carbon, safe and reliable new power system.

[0031] In some embodiments, the anti-drop device is threadedly connected to the bottom wall of the second wire clamping groove 7 of the housing 1.

[0032] In some embodiments, the anti-drop device includes a first fastening bolt 8 and a second fastening bolt 9, which are threadedly connected to the bottom wall of the second wire clamping groove 7 of the housing 1, respectively. The first fastening bolt 8 and the second fastening bolt 9 are staggered along the axial direction of the tightening bolt 4. The axial directions of the first fastening bolt 8 and the second fastening bolt 9 are both perpendicular to the axial direction of the tightening bolt 4.

[0033] With a first tightening bolt 8 and a second tightening bolt 9 staggered along the axis of the tightening bolt 4, after the tightening bolt 4 pushes the push plate 5 in the second clamping groove 7 forward to press the wire, the first tightening bolt 8 and the second tightening bolt 9 on the anti-drop device are tightened in sequence to further fix the push plate 5. The first tightening bolt 8 is tangential to the bottom of the push plate 5, forming a mechanical stop to resist the backward movement tendency of the push plate 5 caused by the tension of the wire, thereby preventing the push plate 5 from moving backward. The second tightening bolt 9 abuts against the side of the push plate 5, generating tangential friction force to further lock the position of the push plate 5 and prevent the push plate 5 from loosening. The design of the first tightening bolt 8 and the second tightening bolt 9 forms a double anti-loosening structure. Under the double action, a constant torque reverse self-locking effect is formed to ensure that the wire clamp will not loosen during long-term operation.

[0034] In some embodiments, the second clamping groove 7 includes a second semi-circular groove 10 and an elongated wire groove 11 that are interconnected. The push plate 5 is slidably disposed in the elongated wire groove 11. The tightening bolt 4 passes through the left side wall of the elongated wire groove 11 of the housing 1 and is connected to the push plate 5. The first tightening bolt 8 and the second tightening bolt 9 are respectively threaded to the bottom wall of the elongated wire groove 11 of the housing 1. The distance between the first tightening bolt 8 and the left side wall of the elongated wire groove 11 is less than the distance between the second tightening bolt 9 and the left side wall of the elongated wire groove 11.

[0035] By providing an elongated wire groove 11, and with the push plate 5 slidably disposed within the elongated wire groove 11, the elongated wire groove 11 limits and guides the sliding direction of the push plate 5, making the pressing of the wire by the push plate 5 more reliable.

[0036] In some embodiments, the push plate 5 is a Y-shaped push plate 5, which is slidably disposed within the elongated wire groove 11.

[0037] The push plate 5 is a Y-shaped push plate 5, and the Y-shaped push plate 5 is slidably disposed in the elongated wire groove 11. The cooperation between the Y-shaped push plate 5 and the elongated wire groove 11 further improves the reliability of the clamping.

[0038] In some embodiments, the tightening bolt 4 is threaded to the left side wall of the elongated wire groove 11 of the housing 1.

[0039] By tightening the bolt 4 and threading it to the left side wall of the elongated wire groove 11, the displacement of the push plate 5 can be precisely adjusted, and the pushing force can be stably transmitted to the push plate 5 to evenly press the wire. It has the advantage of convenient assembly and disassembly.

[0040] In some embodiments, the push plate 5 includes an integrally formed pushing part 12 and a pressing part 13, the pushing part 12 being matched with the elongated wire groove 11, and the pushing part 12 being slidably disposed within the elongated wire groove 11.

[0041] The push plate 5 is provided with a pushing part 12 that matches the elongated wire groove 11. When the push plate 5 slides, the pushing part 12 forms a guiding fit with the inner wall of the elongated wire groove 11.

[0042] In some embodiments, the tightening bolt 4 is provided with an insertion part 14, and the push plate 5 is provided with an insertion hole (not shown in the figure) that matches the insertion part 14, and the insertion part 14 of the tightening bolt 4 is inserted into the insertion hole of the push plate 5.

[0043] By precisely engaging the insertion part 14 with the insertion hole, the pushing force of the tightening bolt 4 is stably transmitted to the push plate 5, which pushes the push plate 5 to move smoothly and evenly to press the wire, ensuring reliable connection and convenient assembly.

[0044] In some embodiments, the insertion part 14 is a cylindrical insertion part 14, and the insertion hole is a cylindrical insertion hole that matches the cylindrical insertion part 14.

[0045] In some embodiments, the first clamping groove 6 includes a first semi-circular groove 15 and a pressure plate mounting groove 16 that are interconnected. The opening directions of the first semi-circular groove 15 and the second semi-circular groove 10 are opposite, and the first semi-circular groove 15 and the second semi-circular groove 10 form an S-shaped structure.

[0046] The S-shaped structure is formed by the opposite openings of the first semi-circular groove 15 and the second semi-circular groove 10. With the cooperation of the pressure plate 3 and the push plate 5, uniform pressing can be achieved, preventing the wire from falling off and enhancing the reliability of mechanical self-locking, making it suitable for operation in confined spaces.

[0047] In some embodiments, the eye bolt 2 is threaded to the right side wall of the first clamping groove 6 of the housing 1, and the eye bolt 2 is rotatably connected to the pressure plate 3.

[0048] The eye bolt 2 is threaded to the right side wall of the first wire clamping groove 6, which facilitates pushing the pressure plate 3 to press the wire, making the operation more convenient.

[0049] In some embodiments, a connecting groove 17 is provided on one side of the pressure plate mounting groove 16 of the housing 1. A closing device 22 is rotatably connected to the connecting groove 17. The closing device 22 includes an integrally formed cylindrical connecting part 18 and a square column closing part 19. The cylindrical connecting part 18 is rotatably connected to the connecting groove 17.

[0050] The cylindrical connecting part 18 is rotatably connected to the connecting groove 17, allowing the closing device 22 to be flexibly adjusted in angle. When the square column closing part 19 is rotated to the closed position, it forms a multi-plane mechanical stop with the housing 1, improving the reliability of anti-loosening and installation efficiency.

[0051] In some embodiments, the cylindrical connecting part 18 has a rotating groove, and a rotating rod 20 is connected in the rotating groove. Both ends of the rotating rod 20 are installed in the connecting groove 17. A torsion spring 21 is installed on the rotating rod 20. One end of the torsion spring 21 is connected to the closing device 22, and the other end of the torsion spring 21 is connected to the housing 1.

[0052] The torsion spring 21 provides an automatic reset preload for the closing device 22. The rotating rod 20 cooperates with the rotating groove to ensure precise rotation. The two ends of the torsion spring 21 are connected to the housing 1 and the closing device 22 respectively. It can continuously apply torque after installation to resist loosening caused by wire vibration and further prevent the wire from coming loose.

[0053] In some embodiments, the rotating rod 20 is made of stainless steel.

[0054] The working principle of this utility model:

[0055] The anti-drop current-guiding splice clamp can be used with an American-style gun-shaped operating lever. By hooking the eye bolt 2 with the hook of the gun, rotating the eye bolt 2 pushes the pressure plate 3 forward, and the pressure plate 3 clamps the wire. The clamp is pistol-shaped, with the push plate 5 acting as a trigger, which can clamp the wire when pushed forward. The pressure plate 3 acts as a firing pin, which clamps the wire forward, thus achieving a tight connection of the wire. By simultaneously opening a first clamping groove 6 and a second clamping groove 7 in the housing 1, and the first clamping groove 6 and the second clamping groove 7 being set as one piece, the wires on both sides can be reliably connected, which can effectively ensure the integrity of the conductive channel.

[0056] Specifically, the push plate 5 is slid into the elongated wire groove 11 of the housing 1, with one side of the push plate 5 flush with the housing 1. The push plate 5 is pre-fixed by a fixed anti-drop wire device to prevent the push plate 5 from sliding left and right.

[0057] The cylindrical insertion part 14 at the end of the tightening bolt 4 engages with the cylindrical insertion hole at the bottom of the push plate 5. By twisting the tightening bolt 4, the push plate 5 is pushed towards the direction of the second semi-circular groove 10. After the bare wire is placed in the second wire clamping groove 7, the push plate 5 presses the bare wire. The first fastening bolt 8 and the second fastening bolt 9 on the anti-drop device are tightened in sequence to further fix the push plate 5. The first fastening bolt 8 is tangent to the bottom of the push plate 5 to prevent the push plate 5 from moving backward. The second fastening bolt 9 abuts against the side of the push plate 5 to generate tangential force and further prevent the push plate 5 from loosening.

[0058] The main functions of this utility model are:

[0059] By incorporating an anti-drop device that passes through the bottom wall of the second clamping groove of the housing and abuts against the push plate, the push plate is further locked in position and prevented from loosening after the tightening bolt pushes the push plate forward to press the conductor. The first and second fixing bolts are staggered along the axis of the tightening bolt. After the tightening bolt pushes the push plate forward to press the conductor, the first and second fixing bolts on the anti-drop device are tightened sequentially to further secure the push plate. The first fixing bolt is tangential to the bottom of the push plate, forming a mechanical stop to resist the backward movement of the push plate due to conductor tension, thus preventing the push plate from moving backward. The second fixing bolt abuts against the side of the push plate, generating tangential friction to further lock the push plate in position and prevent loosening. The design of the first and second fixing bolts forms a double anti-loosening structure, creating a constant torque reverse self-locking effect under the dual action, ensuring that the clamp will not loosen during long-term operation. This utility model discloses a reverse self-locking S-type anti-drop-out current-guiding connector for power line operations, which can significantly reduce the labor intensity of operators, improve operational safety, and provide strong support for building a clean, low-carbon, safe and reliable new power system.
