Description

Technical Field

[0001] This application relates to the technical field of cable installation, and in particular to a conductive cable connection structure and connector. Background Technology

[0002] In today's power distribution systems, distribution cabinets are key equipment, undertaking important functions such as power distribution, control, and protection. Because there are many circuits within a distribution cabinet, and the cables for each circuit need to be connected to the same circuit breaker, but the interface size on the circuit breaker is fixed, it's impossible to secure all the cables within the circuit breaker's interface when there are many. To facilitate the installation of cables for multiple circuits, copper busbars are installed inside the distribution box. These busbars have multiple mounting holes spaced along their length, allowing one end of the busbar to connect to the circuit breaker's interface. Cables for multiple circuits are then threaded through these mounting holes using bolts, and finally, the cables are secured to the copper busbar.

[0003] For example, Chinese patent document CN221669219U discloses a wiring copper busbar for a high-voltage switch, including a female copper busbar and a female copper busbar. The front sidewall of the female copper busbar has evenly spaced connection holes, and the top wall of the female copper busbar has limit grooves. The female copper busbar is integrally stamped from a copper sheet and includes a snap-fit ​​part and a mounting part. The upper end of the snap-fit ​​part is T-shaped, and the upper side of the snap-fit ​​part is bent. The upper side of the front sidewall of the female copper busbar has a mounting part. The mounting part has wiring holes formed by bending backwards on both the left and right sides. The bottom end of the sub-copper busbar is C-shaped. Connecting blocks are provided on both the left and right sides of the inner wall of the wiring hole. The connecting blocks are conical. Clamping screws are provided on both the left and right sides of the rear side wall of the sub-copper busbar. Clamping blocks are provided on both the left and right side walls of the sub-copper busbar. The clamping screws are located on the rear side walls of the clamping blocks. Sliding grooves are provided on the opposite side walls of the clamping blocks on both the left and right sides. The sub-copper busbar is located in the inner cavity of the sliding groove. The T-shaped part of the sub-copper busbar is snapped into the inner cavity of the limiting groove. The mounting hole and the connection hole are aligned. The fixing bolt is installed by passing it through the mounting hole and the connection hole, which facilitates the connection of the mother copper busbar and the sub-copper busbar. The T-shaped part of the sub-copper busbar is snapped and limited by the limiting groove, so that the device limits the connection of the sub-copper busbar. The copper core of the cable to be connected is stripped to a suitable length and inserted into the circular wiring hole. The outer wall of the wiring hole is squeezed by a special wire pressing device to deform and clamp and fix the copper core, which makes it easy for the device to connect the copper core of the cable.

[0004] In the aforementioned related technologies, the T-shaped part of the sub-copper busbar is clamped and limited by the limiting groove, thereby limiting the connection of the sub-copper busbar and fixing it. However, before installation, the installer needs to open multiple connection holes on the copper busbar according to the installation position. Since multiple connection holes need to be opened on the copper busbar, the multiple connection holes will directly cut off the current flow path, forcing the current to detour, thereby reducing the effective conductive cross-sectional area. The electric field strength at the opening may be significantly enhanced, even exceeding the air breakdown threshold, causing partial discharge or corona phenomenon. The edge of the hole may form contact resistance due to oxidation or processing defects, further increasing power loss. Summary of the Invention

[0005] This application provides a conductive cable connection structure and connector, which aims to solve the problem of reduced effective conductive cross-sectional area of ​​copper busbars in related technologies.

[0006] The conductive cable connection structure and connector provided in this application adopt the following technical solution:

[0007] First aspect:

[0008] A conductive cable connection structure includes a copper busbar body slidably connected to a connecting frame. The connecting frame is equipped with a clamping assembly for pressing a copper ring at the end of the conductive cable onto the connecting frame. The connecting frame includes a first vertical plate, a second vertical plate, and a connecting plate. One end of the connecting plate is fixed to the first vertical plate, and the other end is fixed to the second vertical plate. The connecting frame is equipped with an adjusting assembly for driving the clamped conductive cable to slide on the connecting frame. The adjusting assembly includes a first adjusting plate slidably connected to the first vertical plate and a second adjusting plate slidably connected to the second vertical plate. The clamping assembly includes an adjusting ring rotatably connected to the surface of the first adjusting plate, a clamping screw threadedly connected to the adjusting ring, and a clamping ring disposed on the clamping screw. The second adjusting plate is equipped with a support assembly for supporting the clamped conductive cable copper ring. When the clamping screw rotates, it drives the clamping ring to move closer to the second adjusting plate, pressing the copper ring onto the support assembly.

[0009] By adopting the above technical solution, the operator first installs a corresponding number of connecting brackets on the copper busbar body according to the number of conductive cables in the circuit. Then, the copper busbar body is connected to the circuit breaker interface. The copper rings on the corresponding conductive cables are fitted onto the support assembly. The operator holds the adjusting ring with one hand and rotates the clamping screw with the other hand. The clamping screw drives the clamping ring to move closer to the second adjusting plate, so that the clamping ring abuts against the surface of the copper ring, thus fixing the position of the copper ring. Compared with the existing technology, there is no need to open mounting holes on the copper busbar body, avoiding the reduction of the effective conductive cross-sectional area of ​​the copper busbar body. Since the first and second adjusting plates slide on the connecting brackets, when the length of the conductive cable is long, the first and second adjusting plates slide closer to the copper busbar body; when the length of the conductive cable is short, the first and second adjusting plates slide further away from the copper busbar body. Through the setting of the first and second adjusting plates, even if there is an error in the length of the conductive cable cut by the operator, it can still be connected to the copper busbar body, improving the overall installation efficiency of the conductive cables.

[0010] Optionally, the support assembly includes an abutment ring threadedly connected to a second adjusting plate, a limiting ring fixedly installed on the abutment ring, and a support ring passing through the abutment ring. The second adjusting plate is fixedly installed with an adjusting ring, and the support ring is threadedly connected to the adjusting ring on the second adjusting plate. The copper ring to be installed is located on the support ring and abuts against the abutment ring.

[0011] By adopting the above technical solution, when installing the copper ring, the copper ring on the conductive cable is fitted onto the support ring. At this time, the position of the copper ring can be defined. Then, the worker can directly rotate the clamping screw, which drives the clamping ring to move and clamp the copper ring on the support ring. Compared with the existing technology, there is no need to check the position of the bolt and the copper ring during the installation process, making the installation of the copper ring more convenient.

[0012] Optionally, the support ring is provided with a reinforcement component for reinforcing the copper ring abutting against the abutting ring. The reinforcement component includes a reinforcement rod slidably connected to the support ring and an arc-shaped reinforcement plate disposed on the reinforcement rod. The reinforcement rod slides in a direction perpendicular to the axis of the support ring. The support ring is provided with a pushing component for pushing the reinforcement rod and the arc-shaped reinforcement plate to move away from the axis of the support ring. The pushing component causes the arc-shaped reinforcement plate to abut against the inner wall of the copper ring.

[0013] By adopting the above technical solution, the clamping ring abuts against the surface of the copper ring, and the other surface of the copper ring abuts against the surface of the abutting ring, thus fixing the copper ring. Then, by pushing the component, the reinforcing rod is moved, and the reinforcing rod moves the arc-shaped reinforcing plate, so that the arc-shaped reinforcing plate abuts against the inner wall of the copper ring. At this time, the copper ring can be further fixed, thereby improving the stability of the copper ring.

[0014] Optionally, the pushing assembly includes a pushing rod threadedly connected to the support ring and a pushing inclined surface disposed on the pushing rod. The end of the reinforcing rod away from the arc-shaped reinforcing plate is provided with an abutting inclined surface, which abuts against the pushing inclined surface. When the pushing rod moves toward the first adjusting plate, it pushes the reinforcing rod to move away from the axis of the support ring.

[0015] By adopting the above technical solution, when it is necessary to move the reinforcing rod and the arc-shaped reinforcing plate, the push rod is directly rotated and moved towards the first adjusting plate. The push rod is then pushed away from the axis of the support ring by the push slope, so that the arc-shaped reinforcing plate on the reinforcing rod abuts against the inner wall of the copper ring.

[0016] Optionally, a limiting groove is formed on the copper busbar body, the limiting groove is located near the first vertical plate, and a clamping component is provided in the limiting groove to increase the distance between the first vertical plate and the second vertical plate.

[0017] Optionally, the abutting assembly includes a sliding rod slidably connected to the first vertical plate and an elastic sheet fixed to the sliding rod. The elastic sheet includes a first abutting portion, a second abutting portion, a first connecting portion, a second connecting portion, and a third abutting portion. One end of the first abutting portion is fixedly connected to the first connecting portion, and the other end is fixedly connected to the second connecting portion. The end of the first connecting portion away from the first abutting portion is fixedly connected to the second abutting portion, and the end of the second connecting portion away from the first abutting portion is fixedly connected to the third abutting portion.

[0018] Optionally, a groove is provided on the first vertical plate. The groove is arranged along the length of the first vertical plate, and one end of the groove near the connecting plate extends to the connecting plate, so that one end near the connecting plate is in an open state and the other end is in a closed state. A sliding strip is fixedly installed on the first adjusting plate, and the sliding strip is slidably connected in the groove.

[0019] Optionally, an mounting ring is fixedly installed on the clamping ring, the mounting ring is threadedly connected to the clamping screw, the mounting ring is provided with a connecting groove, the connecting groove is provided with an internal thread, and the support ring is provided with an external thread at one end near the first adjusting plate, the support ring being used for threaded connection with the clamping ring.

[0020] By adopting the above technical solution, when the clamping ring moves toward the second adjusting plate, the support ring will be inserted into the connecting groove. Since the clamping ring is provided with a connecting groove and the connecting groove is provided with an internal thread, the support ring and the clamping ring will be threadedly connected, thereby improving the connection strength between the first adjusting plate and the second adjusting plate.

[0021] Optionally, the support ring has an installation groove, and the end of the installation groove near the first adjusting plate has an opening. The reinforcing rod is pushed horizontally along the axis of the support ring through the opening so that the reinforcing rod is placed in the installation groove. The end of the support ring is threaded with a sealing ring for sealing the opening of the installation groove so that the reinforcing rod in the installation groove cannot move along the axis of the support ring.

[0022] The second aspect:

[0023] A conductive cable connector includes a copper busbar body with a connection hole at one end, which is then connected to a bolt in a circuit breaker interface via the connection hole.

[0024] By adopting the above technical solution, when installing multiple conductive cables, these cables can be connected to the circuit breaker via connectors, facilitating the installation of conductive cables with multiple circuits. Specifically, firstly, multiple connecting brackets are fitted onto the copper busbar body, aligning the connecting holes on the copper busbar body with the interfaces on the circuit breaker. Then, the copper busbar body is fixed to the circuit breaker using bolts, thus securing the copper busbar body. After the copper busbar body is fixed, the copper ring on the conductive cable is fitted onto the support ring. Rotating the clamping screw causes the clamping ring to move, pressing the copper ring against the abutment ring. Then, rotating the push rod causes the pushing inclined surface on the push rod to move multiple reinforcing rods and arc-shaped reinforcing plates, causing the arc-shaped reinforcing plates to abut against the inner wall of the copper ring, further securing the copper ring and improving its connection strength.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The first and second adjustment plates slide on the connecting frame. When the conductive cable is long, the first and second adjustment plates slide towards the copper busbar body. When the conductive cable is short, the first and second adjustment plates slide away from the copper busbar body. By setting the first and second adjustment plates, even if there is an error in the length of the conductive cable cut by the worker, it can still be connected to the copper busbar body, thus improving the overall installation efficiency of the conductive cable.

[0027] 2. Rotate the clamping screw, which drives the clamping ring to move closer to the second adjusting plate, so that the clamping ring abuts against the surface of the copper ring, thereby fixing the position of the copper ring. During the connection of conductive cables, there is no need to open mounting holes on the copper busbar body, thus avoiding the reduction of the effective conductive cross-sectional area of ​​the copper busbar body.

[0037] The following combination Figures 1-8 This application will be described in further detail.

[0038] First aspect:

[0039] This application discloses a conductive cable connection structure. (Refer to...) Figures 1 to 5A conductive cable connection structure includes a copper busbar body 1 and a connecting frame 2 slidably connected to the copper busbar body 1. One end of the copper busbar body 1 is connected to a circuit breaker interface. A clamping component 5 is provided on the connecting frame 2 to clamp the copper ring 01 at the end of the conductive cable onto the connecting frame 2. A reinforcing component 4 is provided on the connecting frame 2 to reinforce the copper ring 01 at the end of the clamped conductive cable, thereby improving the connection strength between the conductive cable and the connecting frame 2. An adjusting component 3 is provided on the connecting frame 2 to drive the clamped conductive cable to slide on the connecting frame 2, so that conductive cables of different lengths can be connected to the connecting frame 2. After the copper ring 01 on the conductive cable is clamped onto the connecting frame 2, the current can flow through the circuit breaker to the copper busbar body 1, through the copper busbar body 1 to the connecting frame 2, and finally through the connecting frame 2 to the conductive cable, achieving the effect of a circuit.

[0040] Reference Figures 2 to 4 The connecting frame 2 includes a first vertical plate 21, a second vertical plate 22, and a connecting plate 23. One end of the connecting plate 23 is fixed to the first vertical plate 21, and the other end is fixed to the second vertical plate 22. In this embodiment, the first vertical plate 21, the second vertical plate 22, and the connecting plate 23 are integrally formed, and the material of the first vertical plate 21, the second vertical plate 22, and the connecting plate 23 is copper. The first vertical plate 21, the second vertical plate 22, and the connecting plate 23 form an inverted U-shaped structure. The copper busbar body 1 is located between the first vertical plate 21, the second vertical plate 22, and the connecting plate 23. At this time, the connecting frame 2 can slide on the copper busbar body 1. The number of connecting frames 2 on the copper busbar body 1 can be selected according to the number of circuits of the installed conductive cables.

[0041] Reference Figures 2 to 4 The adjustment assembly 3 includes a first adjustment plate 31 slidably connected to the first vertical plate 21 and a second adjustment plate 32 slidably connected to the second vertical plate 22. The first vertical plate 21 has a groove, which is set along the length of the first vertical plate 21. The end of the groove near the connecting plate 23 extends to the connecting plate 23, so that the end near the connecting plate 23 is in an open state and the other end is in a closed state. A sliding strip is fixedly installed on the first adjustment plate 31. The sliding strip is slidably connected in the groove. Since the upper end of the groove is open, the sliding strip on the first adjustment plate 31 can be inserted into the groove from the upper end. Then, under the action of gravity, the sliding strip will abut against the bottom wall of the groove, thereby realizing the installation of the first adjustment plate 31.

[0042] The second vertical plate 22 is also provided with a sliding groove. The sliding groove is set along the length of the second vertical plate 22, and the end of the sliding groove near the connecting plate 23 extends to the connecting plate 23, so that the end near the connecting plate 23 is in an open state and the other end is in a closed state. A sliding strip is also fixedly installed on the second adjusting plate 32. The sliding strip is slidably connected in the sliding groove. Since the upper end of the sliding groove is open, the sliding strip on the second adjusting plate 32 can be inserted into the sliding groove from the upper end. Then, under the action of gravity, the sliding strip will abut against the bottom wall of the sliding groove, thereby realizing the installation of the second adjusting plate 32.

[0043] Reference Figure 3 , Figure 5 and Figure 6 The clamping assembly 5 includes an adjusting ring 51 rotatably connected to the surface of the first adjusting plate 31, a clamping screw 52 threadedly connected to the adjusting ring 51, and a clamping ring 53 disposed on the clamping screw 52. Meanwhile, a support assembly 6 is disposed on the second adjusting plate 32, which is used to support the copper ring 01 on the conductive cable.

[0044] Reference Figures 5 to 8 An mounting ring 11 is fixedly installed on the clamping ring 53. A threaded groove is provided at the end of the clamping screw 52 away from the rotating groove 12. The mounting ring 11 is inserted into the threaded groove and is threadedly connected to the clamping screw 52. In the initial state, the clamping screw 52 does not protrude from the side of the first adjusting plate 31 near the first vertical plate 21. After the first adjusting plate 31 is installed on the first vertical plate 21, the clamping screw 52 on the first adjusting plate 31 is rotated so that the clamping screw 52 extends out of the first vertical plate 21. At this time, the mounting ring 11 on the clamping ring 53 is threadedly connected to the clamping screw 52. After the clamping ring 53 is installed, the copper ring 01 is directly sleeved on the support assembly 6. The clamping ring 53 continues to move through the clamping screw 52 to clamp and fix the copper ring 01.

[0045] To facilitate the rotation of the clamping screw 52, ​​a rotating groove 12 is provided on the end face of the clamping screw 52. The rotating groove 12 is hexagonal. When rotating the clamping screw 52, ​​the operator inserts a wrench into the rotating groove 12. Rotating the wrench will drive the clamping screw 52 to rotate. The clamping screw 52 drives the clamping ring 53 to move. The clamping ring 53 presses the copper ring 01 onto the second vertical plate 22, thereby achieving the clamping of the copper ring 01.

[0046] Reference Figures 5 to 8The support assembly 6 includes an abutment ring 61 threadedly connected to the second adjusting plate 32, a limiting ring 62 fixedly mounted on the abutment ring 61, and a support ring 63 passing through the abutment ring 61. An adjusting ring 51 is fixedly mounted on the second adjusting plate 32. The support ring 63 is threadedly connected to the adjusting ring 51 on the second adjusting plate 32. One end of the support ring 63 extends out of the abutment ring 61, and the other end extends out of the adjusting ring 51. The support ring 63 is used to support the copper ring 01 on the conductive cable. The diameter of the limiting ring 62 is larger than the diameter of the abutment ring 61. The connecting bracket 2 is inserted into the copper busbar. After the main body 1 is attached, the abutment ring 61 is threaded onto the second vertical plate 22 from the side of the second vertical plate 22 near the first vertical plate 21, and the limiting ring 62 abuts against the side of the second vertical plate 22 near the first vertical plate 21. When it is necessary to fix the conductive cable, the copper ring 01 on the conductive cable is put onto the support ring 63. The operator fixes the adjusting ring 51 with one hand and rotates the clamping screw 52 with the other hand. The clamping screw 52 drives the clamping ring 53 to move towards the second adjusting plate 32. Finally, the support ring 63 presses the copper ring 01 onto the abutment ring 61.

[0047] A connecting groove is provided on the mounting ring 11, and an internal thread is provided in the connecting groove. The end of the support ring 63 near the first adjusting plate 31 is provided with an external thread. In this embodiment, the side near the first adjusting plate 31 is used to extend into the connecting groove on the clamping ring 53. Then, the support ring 63 is threadedly connected to the clamping ring 53 through the connecting groove. During the process of the clamping screw 52 driving the clamping ring 53 to move towards the abutting ring 61, one end of the support ring 63 will be inserted into the connecting groove, and then the support ring 63 will be threadedly connected to the connecting groove.

[0048] In this embodiment, the thread direction on the clamping screw 52 is the same as the thread direction on the abutment ring 61. When the clamping screw 52 and the abutment ring 61 are rotated in the same direction, the clamping screw 52 will drive the clamping ring 53 to move closer to the abutment ring 61. The abutment ring 61 is threadedly fixed on the second adjusting plate 32, and the limiting ring 62 abuts against the surface of the second adjusting plate 32. During the rotation of the clamping ring 53 driven by the clamping screw 52, ​​since the abutment ring 61 cannot continue to rotate, the support ring 63 can be better threadedly connected to the connecting groove. When the clamping screw 52 drives the clamping ring 53 to move closer to the second adjusting plate 32, the support ring 63 will be threadedly connected to the connecting groove. Since the support ring 63 is threadedly connected to the adjusting ring 51, it will not rotate on the adjusting ring 51 at this time.

[0049] When the clamping ring 53 presses the copper ring 01 onto the abutment ring 61, the operator holds the clamping screw 52 with one hand and rotates the adjusting ring 51 with the other. During the rotation of the adjusting ring 51, it will push the first adjusting plate 31 and the first vertical plate 21 to move towards the second adjusting plate 32. Then the first adjusting plate 31 will better abut against the copper busbar body 1. The first vertical plate 21 and the second vertical plate 22 can clamp the connecting frame 2 onto the copper busbar body 1, so that the entire connecting frame 2 cannot move.

[0050] Reference Figures 5 to 8 A mounting groove 13 is provided on the support ring 63, and the reinforcing component 4 is disposed in the mounting groove 13. The reinforcing component 4 includes a reinforcing rod 41 slidably connected in the mounting groove 13 and an arc-shaped reinforcing plate 42 disposed on the reinforcing rod 41. The reinforcing rod 41 slides in a direction perpendicular to the axis of the support ring 63, and the arc-shaped reinforcing plate 42 is fixed to the reinforcing rod 41 by bolts. A pushing component 7 is provided on the support ring 63. The pushing component 7 is used to push the reinforcing rod 41 and the arc-shaped reinforcing plate 42 to move away from the axis of the support ring 63, so that the arc-shaped reinforcing plate 42 abuts against the inner wall of the copper ring 01, thereby improving the fixing strength of the copper ring 01.

[0051] Reference Figures 5 to 8 An opening is provided at one end of the mounting groove 13 near the first adjusting plate 31. The reinforcing rod 41 can be pushed horizontally along the axis of the support ring 63 through the opening, so that the reinforcing rod 41 is placed in the mounting groove 13. A sealing ring 14 is threadedly connected to the end of the support ring 63. The sealing ring 14 is used to seal the opening of the mounting groove 13, so that the reinforcing rod 41 in the mounting groove 13 cannot move along the axis of the support ring 63. In this embodiment, the cross-section of the reinforcing rod 41 gradually decreases along the direction away from the axis of the support ring 63. At this time, it can prevent the reinforcing rod 41 in the mounting groove 13 from falling off under the action of gravity, thereby improving the stability of the reinforcing rod 41 and the arc-shaped reinforcing plate 42.

[0052] Reference Figure 3 , Figures 5 to 8 The pushing component 7 includes a pushing rod 71 threadedly connected to the support rod and a pushing inclined surface 72 disposed on the pushing rod 71. The pushing inclined surface 72 is arranged in a circle around the circumference of the pushing rod 71. An abutting inclined surface is provided at the end of the reinforcing rod 41 away from the arc-shaped reinforcing plate 42. The abutting inclined surface abuts against the pushing inclined surface 72. Under the action of the pushing inclined surface 72, the cross section of the pushing rod 71 gradually decreases towards the first adjusting plate 31. In this embodiment, three mounting slots 13 are provided, which are spaced apart around the circumference of the support ring 63. Each of the three mounting slots 13 is slidably connected to a reinforcing rod 41. An arc-shaped reinforcing plate 42 is fixedly installed on each reinforcing rod 41 by bolts. The setting of three arc-shaped reinforcing plates 42 can improve the fixing strength of the copper ring 01.

[0053] When the second adjusting plate 32 is installed onto the second vertical plate 22, under the action of gravity, the second adjusting plate 32 is at the lowest end of the second vertical plate 22. Then, the abutment ring 61 is installed. After the abutment ring 61 is installed, the support ring 63 is threaded onto the abutment ring 61. One end of the support ring 63 extends between the first adjusting plate 31 and the second adjusting plate 32. The three reinforcing rods 41 with arc-shaped reinforcing plates 42 are slid from the opening of the mounting groove 13 into the mounting groove 13. Then, the opening of the mounting groove 13 is limited by the sealing ring 14, so that the length of the side of the sealing ring 14 away from the first adjusting plate 31 is less than the length of the reinforcing rod 41. The length of the reinforcing rod 41 at its widest position is such that the reinforcing rod 41 in the mounting groove 13 will not detach under gravity. Finally, the copper ring 01 with conductive cable can be fitted onto the support ring 63, and the uppermost arc-shaped reinforcing plate 42 abuts against the inner wall of the copper ring 01. After the clamping ring 53 abuts against the surface of the copper ring 01, the other side of the copper ring 01 abuts against the abutting ring 61, and the copper ring 01 is clamped. Then, the push rod 71 rotates, and the push inclined surface 72 on the push rod 71 pushes the three reinforcing rods 41 to move simultaneously, so that the three arc-shaped reinforcing plates 42 abut against the inner wall of the copper ring 01, thereby further fixing the copper ring 01.

[0054] Reference Figure 1 , Figures 5 to 8 A limiting groove 15 is provided on the copper busbar body 1. The limiting groove 15 is located near the first vertical plate 21 and is arranged along the length direction of the copper busbar body 1. A clamping component 8 is provided in the limiting groove 15. The clamping component 8 is used to increase the distance between the first vertical plate 21 and the second vertical plate 22, reduce the friction between the first vertical plate 21 and the second vertical plate 22 and the connecting frame 2, and make it easier for the connecting frame 2 to slide on the copper busbar body 1.

[0055] Reference Figure 1 , Figures 5 to 8The clamping assembly 8 includes a sliding rod 81 slidably connected to the first vertical plate 21 and an elastic sheet 82 fixed to the sliding rod 81. The elastic sheet 82 is made of copper and includes a first abutting portion 821, a second abutting portion 822, a first connecting portion 824, a second connecting portion 825, and a third abutting portion 823. One end of the first abutting portion 821 is fixedly connected to the first connecting portion 824, and the other end is fixedly connected to the second connecting portion 825. The end of the first connecting portion 824 away from the first abutting portion 821 is fixedly connected to the second abutting portion 822, and the end of the second connecting portion 825 away from the first abutting portion 821 is fixedly connected to the third abutting portion 823. In this example, the first abutting part 821, the second abutting part 822, the first connecting part 824, the second connecting part 825, and the third abutting part 823 are integrally formed. When the first adjusting plate 31 and the first vertical plate 21 are not pressed, the first connecting part 824 and the second connecting part 825 are in an inclined state, the first vertical plate 21 is inclined, and the first vertical plate 21 does not contact the surface of the copper busbar body 1. When the first adjusting plate 31 and the first vertical plate 21 are pressed, the first abutting part 821, the second abutting part 822, the first connecting part 824, the second connecting part 825, and the third abutting part 823 are on the same plane, and the first vertical plate 21 abuts against the surface of the copper busbar body 1.

[0056] The implementation principle of a conductive cable connection structure in this application embodiment is as follows: First, the copper busbar body 1 is fixed on the circuit breaker interface. As needed, multiple connecting frames 2 are fitted on the copper busbar body 1. Each connecting frame 2 is equipped with a first adjusting plate 31 and a second adjusting plate 32. A clamping screw 52 and a clamping ring 53 are installed on the first adjusting plate 31, and an abutment ring 61 and a support ring 63 are installed on the second adjusting plate 32. After all connecting frames 2 are installed, the copper ring 01 on each conductive cable is fitted on the support ring 63. The worker fixes the adjusting ring 51 with one hand and rotates the clamping screw 52 with the other hand. The clamping screw 52 drives the clamping ring 53 to move closer to the second adjusting plate 32. Finally, the clamping ring 53 abuts against the surface of the copper ring 01, and the other side of the copper ring 01 abuts against the abutment ring 61, thus clamping and fixing the copper ring 01.

[0057] After the clamping ring 53 fixes the copper ring 01, the operator rotates the push rod 71. The push ramp 72 on the push rod 71 pushes the three reinforcing rods 41 to move simultaneously, so that the three arc-shaped reinforcing plates 42 all abut against the inner wall of the copper ring 01, further fixing the copper ring 01. When the clamping ring 53 presses the copper ring 01 against the abutment ring 61, the operator fixes the clamping screw 52 with one hand and rotates the adjusting ring 51 with the other hand. During the rotation of the adjusting ring 51, it will push the first adjusting plate 31 and the first vertical plate 21 to move towards the second adjusting plate 32. Then the first adjusting plate 31 will abut against the copper busbar body 1 better. The first vertical plate 21 and the second vertical plate 22 can clamp the connecting frame 2 onto the copper busbar body 1, so that the entire connecting frame 2 cannot move, improving the stability of the connecting frame 2.

[0058] The second aspect:

[0059] A conductive cable connector includes a copper busbar body 1 and a connecting frame 2 slidably connected to the copper busbar body 1. The connecting frame 2 is provided with a clamping component 5 for pressing the copper sheet at the end of the conductive cable onto the connecting frame 2. One end of the copper busbar body 1 is provided with a connecting hole, which is connected to a bolt in the circuit breaker interface through the connecting hole.

[0060] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
