Description

Technical Field

[0001] This utility model relates to the field of electrical engineering technology, specifically to a live-connection bus clamp. Background Technology

[0002] Traditional emergency power supply operations and low-voltage transformer area renovation operations are characterized by their reliance on power outage operations. The process revolves around "power outage-construction-power restoration," mainly targeting sudden power outages (such as line faults or equipment damage). The goal is to quickly restore power, but this requires first disconnecting the original faulty line, then constructing wiring and connecting the emergency power supply. Traditional operations require completely disconnecting the main power supply and then connecting the wires by manually tightening bolts and connecting cables, which carries a high risk of electric shock. To meet market needs, a live-line connection busbar clamp is now required.

[0003] Existing bus clamps are not safe and reliable enough in use, which means that the bolts or clamping mechanism cannot be subjected to uniform force, and the electrical connection reliability requirements cannot be met. In addition, existing bus clamps are inconvenient to operate when changing the contact teeth, which means that the bus clamps cannot guarantee the piercing effect on the insulation layer of the busbar surface, making the electrical connection of the bus clamps unstable. Utility Model Content

[0004] The purpose of this utility model is to provide a live-connection bus clamp to solve the problems mentioned in the background art, such as the lack of safety and reliability in the use of bus clamps and the inconvenience of changing contact teeth.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a live-connection bus clamp, comprising a bus clamp body, the bus clamp body including a female coupler plug, a connecting rod, a clamp head, a moving block, a fixed clamp hand, a movable clamp hand, and a moving rod. The surface of the female coupler plug is provided with a connecting rod, the surface of the connecting rod is fitted with a clamp head, and the internal thread of the connecting rod provides a moving rod. A fixed clamp hand is provided at the bottom of the clamp head, and a movable clamp hand is also provided at the bottom of the clamp head. Contact teeth are provided on the inner walls of the movable clamp hand and the fixed clamp hand. Two sets of locking blocks are symmetrically installed on the surfaces on both sides of the contact teeth. A busbar is provided on one side of the bus clamp body. The fixed clamp hand and the movable clamp hand are used for clamping the busbar. A moving block is provided inside the clamp head. A safe and reliable mechanism is provided on the surface of the bus clamp body. A convenient replacement mechanism is provided on the surfaces of the fixed clamp hand, the movable clamp hand, the contact teeth, and the locking blocks.

[0006] Preferably, the female coupler plug can rotate 360 ​​degrees to adapt to the horizontal and vertical busbar directions. The female coupler plug is used to connect with external cables to realize power transmission. The moving rod can reciprocate within the connecting rod. The clamp head is connected to the female coupler plug through the moving rod. The surface of the moving block is fixed to the surface of the moving clamp hand. One side of the moving block is fixed to the surface of one end of the moving rod.

[0007] Preferably, the safe and reliable mechanism includes a torque wrench, an elastic locking block, a fixing screw sleeve, a guide block, and a limiting groove. The inner wall of the clamp head is provided with a limiting groove. A guide block is installed on the surface at the top position of the moving block. The guide block and the surface of the limiting groove slide against each other. A torque wrench is provided on the surface of the female connector plug. One end of the torque wrench extends into the interior of the moving rod.

[0008] Preferably, the torque wrench has two sets of elastic locking blocks symmetrically installed on its surface. The elastic locking blocks engage with the inner wall of the moving rod. The moving rod is fitted with a fixing screw sleeve, which engages with the inner wall of the female connector of the female coupler.

[0009] Preferably, the easy-to-replace mechanism consists of a snap-fit ​​groove, a clip, a slot, a mounting groove, and a mounting block. The surfaces of the fixed clamp hand and the movable clamp hand are provided with snap-fit ​​grooves. One end of the snap-fit ​​block extends into the interior of the snap-fit ​​groove, and a clip is installed on the surface of the snap-fit ​​groove.

[0010] Preferably, the surface of the latching block is provided with a slot for engaging with the clip, the surface of the contact teeth is symmetrically provided with two sets of mounting blocks, and the inner walls of the fixed clamping hand and the movable clamping hand are symmetrically provided with two sets of mounting grooves for engaging with the mounting blocks.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the live connection bus clamp not only ensures that the bolt or clamping mechanism is subjected to uniform force when the bus clamp is used, thus meeting the requirements for electrical connection reliability, but also ensures that the bus clamp can penetrate the insulation layer on the surface of the busbar, making the electrical connection of the bus clamp more stable.

[0012] 1. With a safe and reliable mechanism, the user places the torque wrench on the surface of the female coupler plug, causing the elastic locking block on the surface of the torque wrench to automatically engage with the inner wall of the moving rod, thus locking the torque wrench and the moving rod together. The user rotates the torque wrench, which causes the moving rod and the fixing sleeve to rotate inside the female coupler plug. Under the threaded engagement between the fixing sleeve and the inner wall of the female coupler plug, the moving rod moves inside the connecting rod. At this time, the moving rod drives the moving block to slide inside the clamp head. When the moving block moves, it drives the moving clamp hand to move from the bottom of the clamp head towards the side of the fixed clamp hand. Under the combined action of the guide block and the limiting groove, the moving clamp hand is guided, realizing the safe and reliable function of the bus clamp. This ensures that the bolt or clamp body clamping mechanism is subjected to uniform force during use, meeting the electrical connection reliability requirements.

[0013] 2. With a convenient replacement mechanism, the user first moves the movable clamp hand away from the fixed clamp hand to reset it. Then, the user pulls the contact teeth on the inner wall of both the fixed and movable clamp hands, causing the contact teeth to move the locking block away from the locking groove. The locking piece on the inner wall of the locking groove moves away from the inside of the groove. At this time, the contact teeth move the mounting block away from the inside of the mounting groove, allowing the contact teeth and locking block to be removed from the inner wall of the fixed and movable clamp hands respectively. The contact teeth can then be replaced, enabling the bus clamp to easily replace the contact teeth. This ensures that the bus clamp can penetrate the insulation layer on the surface of the busbar during use, making the electrical connection of the bus clamp more stable. Attached Figure Description

[0022] The present invention provides a structure for a live-connection bus clamp as follows: Figures 1 to 5As shown, the device includes a bus clamp body 1, which comprises a female coupler plug 11, a connecting rod 12, a clamp head 13, a moving block 14, a fixed clamp hand 15, a moving clamp hand 16, and a moving rod 17. The female coupler plug 11 has the connecting rod 12 mounted on its surface. The female coupler plug 11 can rotate 360° to adapt to the horizontal and vertical directions of the busbar 101. The female coupler plug 11 is used to connect to external cables for power transmission. The clamp head 13 is mounted on the surface of the connecting rod 12, and the moving rod 17 is threaded inside the connecting rod 12. The moving rod 17 can reciprocate within the connecting rod 12. The clamp head 13 is connected to the moving rod 17 via the moving rod 17. The clamp head 13 is connected to the female connector 11. A fixed clamp hand 15 is provided on the surface at the bottom of the clamp head 13. A movable clamp hand 16 is also provided at the bottom of the clamp head 13. Contact teeth 18 are provided on the inner walls of the movable clamp hand 16 and the fixed clamp hand 15. Two sets of latching blocks 181 are symmetrically installed on the surfaces on both sides of the contact teeth 18. A busbar 101 is provided on one side of the busbar 101. The fixed clamp hand 15 and the movable clamp hand 16 are used to clamp the busbar 101. A movable block 14 is provided inside the clamp head 13. The surface of the movable block 14 is fixed to the surface of the movable clamp hand 16. One side of the movable block 14 is fixed to the surface of one end of the movable rod 17.

[0023] Furthermore, such as Figure 4 and Figure 5 As shown, the surface of the manifold clamp body 1 is provided with a safety and reliability mechanism 2. The safety and reliability mechanism 2 includes a torque wrench 21, an elastic locking block 22, a fixing screw sleeve 23, a guide block 24, and a limiting groove 25. The inner wall of the clamp head 13 is provided with a limiting groove 25. A guide block 24 is installed on the surface of the top position of the moving block 14. The surfaces of the guide block 24 and the limiting groove 25 slide against each other. The surface of the female connector plug 11 of the female coupler is provided with a torque wrench 21. One end of the torque wrench 21 extends into the interior of the moving rod 17. Two sets of elastic locking blocks 22 are symmetrically installed on the surface of the torque wrench 21. The elastic locking blocks 22 are engaged with the inner wall of the moving rod 17. A fixing screw sleeve 23 is fitted on the surface of the moving rod 17. The fixing screw sleeve 23 is threadedly engaged with the inner wall of the female connector plug 11 of the female coupler.

[0024] During implementation, the user places the torque wrench 21 on the surface of the female connector 11 of the female coupler, causing the elastic locking block 22 on the surface of the torque wrench 21 to automatically engage with the inner wall of the moving rod 17, thus locking the torque wrench 21 and the moving rod 17 together. The user rotates the torque wrench 21, which causes the moving rod 17 and the fixing sleeve 23 to rotate inside the female connector 11. Under the threaded engagement between the fixing sleeve 23 and the inner wall of the female connector 11, the moving rod 17 moves inside the connecting rod 12. At this time, the moving rod 17 drives the moving block 1... 4. Sliding inside the clamp head 13, when the moving block 14 moves, the moving block 14 drives the moving clamp hand 16 to move from the bottom of the clamp head 13 to the side of the fixed clamp hand 15. Under the combined action of the guide block 24 and the limiting groove 25, the moving clamp hand 16 is guided. The torque wrench 21 can apply a tightening torque of 10 N·m, and tighten it evenly in two stages. The first pre-tightening is 5 N·m, and the second tightening is 10 N·m. This ensures that the bolt or clamp body clamping mechanism is subjected to uniform force, meets the electrical connection reliability requirements, avoids risks such as "lack of connection", and realizes the safe and reliable function of the bus clamp.

[0025] Furthermore, such as Figure 5 and Figure 6 As shown, the surfaces of the fixed clamping hand 15, the movable clamping hand 16, the contact teeth 18, and the locking block 181 are provided with a convenient replacement mechanism 3. The convenient replacement mechanism 3 is composed of a locking groove 31, a locking piece 32, a locking groove 33, a mounting groove 34, and a mounting block 35. The fixed clamping hand 15 and the movable clamping hand 16 have locking grooves 31 on their surfaces. One end of the locking block 181 extends into the interior of the locking groove 31. The locking piece 32 is installed on the surface of the locking groove 31. The locking block 181 has a locking groove 33 on its surface for engaging with the locking piece 32. Two sets of mounting blocks 35 are symmetrically installed on the surface of the contact teeth 18. Two sets of mounting grooves 34 are symmetrically opened on the inner walls of the fixed clamping hand 15 and the movable clamping hand 16 for engaging with the mounting blocks 35.

[0026] In practice, the user first moves the movable clamp hand 16 to the side away from the fixed clamp hand 15 to reset it. Then, the user pulls the contact teeth 18 on the inner wall of the fixed clamp hand 15 and the movable clamp hand 16 respectively, so that the contact teeth 18 drive the locking block 181 to the side away from the locking groove 31. The locking piece 32 on the inner wall of the locking groove 31 moves away from the inside of the locking groove 33. At this time, the contact teeth 18 drive the mounting block 35 away from the inside of the mounting groove 34. The contact teeth 18 and the locking block 181 can be removed from the inner wall of the fixed clamp hand 15 and the movable clamp hand 16 respectively, and the contact teeth 18 can be replaced to realize the function of convenient replacement of the contact teeth 18 of the bus clamp.

[0027] Working principle: In use, first place the bus clamp body 1 in the designated position. The user holds the female connector 11 of the female coupler and places the clamp head 13 above the busbar 101, so that the busbar 101 is located between the fixed clamp hand 15 and the movable clamp hand 16 at the bottom of the clamp head 13. The surface of the busbar 101 is in contact with the surface of the contact teeth 18 on the inner wall of the fixed clamp hand 15. The female connector 11 can be connected to the 16BV male coupler plug of the generator output cable for quick connection. This connection handle can rotate 360° to adapt to the horizontal and vertical directions of the busbar 101, which can minimize the stress on the cable. The user places the torque wrench 21 on the surface of the female connector 11, so that the elastic locking block 22 on the surface of the torque wrench 21 automatically locks into the inner wall of the movable rod 17, locking the torque wrench 21 and the movable rod 17. The user rotates the torque wrench 21, which moves the movable rod under the action of the torque wrench 21. 17 and the fixing sleeve 23 rotate inside the female connector 11 of the female coupler. Under the threaded engagement between the fixing sleeve 23 and the inner wall of the female connector 11, the moving rod 17 moves inside the connecting rod 12. At this time, the moving rod 17 drives the moving block 14 to slide inside the clamp head 13. When the moving block 14 moves, the moving block 14 drives the moving clamp hand 16 to move towards the side of the fixed clamp hand 15 at the bottom of the clamp head 13. Under the combined action of the guide block 24 and the limiting groove 25, the moving clamp hand 16 is guided. The torque wrench 21 can apply a tightening torque of 10 N·m. Tighten evenly in two stages. The first pre-tighten to 5 N·m and the second tighten to 10 N·m to ensure that the bolt or clamp body clamping mechanism is subjected to uniform force, meet the electrical connection reliability requirements, avoid risks such as "lack of connection", so as to realize the safe and reliable function of the bus clamp. Thus, when the bus clamp is used, it can ensure that the bolt or clamp body clamping mechanism is subjected to uniform force and meet the electrical connection reliability requirements.

[0028] Subsequently, the bus clamp body 1 is connected to the cable through a standard 16BV pre-interface, and then the fixed clamp hand 15 and the movable clamp hand 16 of the bus clamp body 1 are docked with the busbar 101. The entire operation can be compressed to 5-10 minutes, greatly shortening the power outage time and significantly improving work efficiency. The outer shells of the female connector plug 11, connecting rod 12 and clamp head 13 of the female coupler are made of insulating material, so the human body does not need to directly contact the live parts during operation and can maintain a safe distance, avoiding the risk of electric shock from the source and ensuring greater safety during operation.

[0029] Subsequently, the movable clamping hand 16 can move away from or closer to the fixed clamping hand 15, adapting to clamping busbars 101 of different sizes. It is highly flexible and easy to use. Under the action of the contact teeth 18, it pierces the insulation layer on the surface of the busbar 101. The contact teeth 18 have a limited service life and need to be replaced periodically. The user first moves the movable clamping hand 16 back to the side away from the fixed clamping hand 15, and then pulls the contact teeth 18 on the inner wall of the fixed clamping hand 15 and the movable clamping hand 16 respectively, so that the contact teeth 18 drive the latching block 181 away from the latching groove 31. As the clamp moves, the locking piece 32 on the inner wall of the locking groove 31 moves away from the inside of the locking groove 33. At this time, the contact teeth 18 drive the mounting block 35 away from the inside of the mounting groove 34, so that the contact teeth 18 and the locking block 181 can be removed from the inner walls of the fixed clamp hand 15 and the moving clamp hand 16 respectively, and the contact teeth 18 can be replaced. This enables the bus clamp to easily replace the contact teeth 18, thereby ensuring the piercing effect of the insulation layer on the surface of the busbar 101 when the bus clamp is used, making the electrical connection of the bus clamp more stable, and finally completing the use of the bus clamp.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
