Description

Technical Field

[0001] This invention relates to the field of busbar trunking application technology, and in particular to a multi-head quick-connect air-type busbar trunking and its assembly method. Background Technology

[0002] Modern high-rise buildings and large workshops require enormous amounts of electrical energy. To cope with the massive loads and the hundreds or thousands of amperes of current required, safe and reliable transmission equipment is essential. Busbar systems are an excellent choice. Busbar systems are highly efficient power distribution devices that are particularly suited to the increasingly tall buildings and large-scale factories that require economical and rational wiring. Due to the increasing power needs of buildings, factories, and other structures, and the growing trend of these needs, using traditional wiring methods, such as conduit wiring, presents many difficulties during construction. Moreover, simplifying the power distribution system is almost impossible when it needs to be changed. However, using busbars makes it very easy to achieve the desired results and also makes the building more aesthetically pleasing.

[0003] Existing busbar trunking typically consists of two end faces during assembly, and installation usually involves directly connecting and fixing the two busbar trunking sections. When multiple pathways are required, an additional installation pathway for the busbar trunking needs to be created, increasing both cost and installation space occupancy, leading to higher maintenance costs later on. Furthermore, the use of bolts for connection during busbar trunking installation necessitates that workers carry different tools, increasing their workload and reducing installation efficiency. Therefore, this invention proposes a multi-head quick-connect air-type busbar trunking and its assembly method. Summary of the Invention

[0004] The technical problem to be solved by this invention is to provide a multi-head quick-connect air-type busbar trunking and its assembly method. By setting the conductive copper busbar inside the busbar trunking to a multi-connector configuration, multiple busbar trunkings can be connected and fixed in multiple directions as needed when they are arranged and installed, improving the flexibility of installation and avoiding the problem of low space utilization caused by traditional multi-busbar trunking installation. At the same time, a quick-release structure is provided at the plug-in point of the busbar trunking, so that the busbar trunking can be quickly locked and fixed by simply plugging the end face together, improving the convenience of installation and the stability during use, and also facilitating quick disassembly during later inspection and maintenance.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A multi-head quick-connect air-type busbar trunking includes multiple conductive copper busbars. Multiple conductive terminals are symmetrically fixedly connected to the sidewalls of the multiple conductive copper busbars near one end for transmitting multiple circuit currents and connecting multiple electrical devices. Multiple stabilizers are respectively snapped onto the outer wall of the conductive copper busbars for fixing the conductive copper busbars during assembly. Two protective shells are symmetrically snapped onto the sidewalls of the multiple conductive copper busbars. Mounting blocks are symmetrically bolted to the end faces of both protective shells for protecting the conductive copper busbars during installation. Two heat dissipation side plates are symmetrically bolted to the sidewalls of the protective shells, and each outer wall is provided with multiple heat dissipation fins for protecting the internal conductive copper busbars in conjunction with the protective shells. A plug-in male connector is bolted to one end of the protective shell for connecting and fixing multiple busbar trunking sections to be connected. Multiple plug-in female connectors are respectively installed on the other end of the conductive copper busbars and multiple conductive terminals for plugging and fixing with the busbar trunking sections to be connected via the plug-in male connectors.

[0006] The present invention is further configured such that each of the plurality of stabilizers is provided with a plurality of ventilation slots, which are respectively distributed alternately with a plurality of conductive copper busbars.

[0007] The above technical solution facilitates the dissipation of high temperatures generated during the use of the busbar trunking through the ventilation channels, thus enabling heat dissipation from the internal high temperatures.

[0008] The present invention is further configured such that: the male connector includes a mounting plate bolted to the mounting block, a boss is provided at the middle of the side wall of the mounting plate, and plug plates are symmetrically arranged on both sides of the boss, the two plug plates are plugged into the two sides of the female connector, and a plug groove is provided at the middle of the end face of the two plug plates.

[0009] The above technical solution uses an mounting plate installed on the end face of the protective housing, so that the boss can correspond to the end face of the plug-in bracket. The plug-in plate facilitates the connection and fixation of the two busbars when plugging them in, and the plug-in slot facilitates the engagement and fixation of the plug-in bracket and the plug-in plate.

[0010] The present invention is further configured such that: the plug-in female includes a plug frame bolted to the protective shell and plugged into the conductive end; multiple contact elements are evenly engaged at the middle position of the inner wall of the plug frame, and the contact elements are arranged in a Z-shape; a protective frame is slidably connected to the outer wall of the plug frame; and engaging components are symmetrically bolted to the middle position of the side wall of the plug frame.

[0011] Through the above technical solutions, contact components can be used to connect and energize the conductive copper busbars inside the two plug-in busbars, protective frames can be used to protect and fix the contact positions of the busbars, and snap-fit ​​components can be used to further reinforce and stabilize the male and female plug-in connectors, thereby improving the stability of the busbars during installation and use.

[0012] The present invention is further configured such that: the inner top and inner bottom of the protective frame are symmetrically provided with sliding strips near the middle position, and are slidably connected to the sliding grooves opened near the middle position of the top and bottom of the plug-in frame through the sliding strips, and can also slide into the corresponding grooves symmetrically opened near the middle position of the top and bottom of the boss.

[0013] The above technical solution facilitates the sliding of the protective frame on the connector bracket, allowing it to slide onto the boss and seal the connection between the male and female connectors, preventing the entry of external dust.

[0014] The invention is further configured such that: positioning shafts are symmetrically fixedly connected to the middle of the side wall of the protective frame near the center; the outer walls of the two positioning shafts are rotatably connected to sleeves; pressure blocks are fixedly connected to the middle of the side walls of the two sleeves; adjusting bolts are provided through the pressure grooves opened in the middle of the two pressure blocks, and the adjusting bolts are threaded to the side wall of the protective frame; rocker arms are fixedly connected to the middle of the side of the two sleeves away from the pressure blocks; limit springs are provided through the end faces of the two rocker arms; adjusting nuts are threadedly connected to the end faces of the two rocker arms, and are respectively pressed against the end faces of the limit springs.

[0015] The above technical solution utilizes adjusting bolts to drive the pressure block to rotate on the positioning shaft via the sleeve connected to the end face. This causes the rocker arm to bend the limiting spring on the end face, thereby moving the protrusion away from the limiting groove on the plug plate. This facilitates the disassembly of the busbar joint. Furthermore, adjusting nuts can be used to bend and adjust the limiting spring on the rocker arm to a certain extent.

[0016] The present invention is further configured such that: the sidewalls of the two limiting spring pieces are provided with protrusions near the end face, and are respectively engaged with multiple limiting grooves opened on opposite walls of the two plug-in plates through the protrusions; the end faces of the two limiting spring pieces are inclined, and an adjustment groove is opened in the middle of each.

[0017] Through the above technical solution, the protrusion on the side wall of the limiting spring can limit and engage the limiting groove set on the inserted plug plate, thereby improving the stability of the busbar trunking during plugging. Furthermore, the adjustment groove facilitates the movement and tightening of the rocker arm, making it easier for the protrusion to move away from the limiting groove.

[0018] The present invention is further configured such that: the engaging assembly includes a positioning block, a rotating shaft is rotatably connected to the middle of the side wall of the positioning block, a knob is fixedly connected to the end face of the rotating shaft, a rotating rod is fixedly connected to the end of the rotating shaft away from the knob, and two locking pins are movably connected to the two ends of the rotating rod, the two locking pins respectively penetrate the side wall of the positioning block and are slidably connected thereto, and the end faces of the two locking pins can engage with the locking grooves opened in the inner wall of the insertion groove, and connecting pins are fixedly connected to the opposite end faces of the two locking pins, and springs are sleeved on the outer walls of the two connecting pins, and the end faces of the springs abut against the inner side wall of the positioning block.

[0019] The above technical solution utilizes an internal spring to elastically reset the squeezed pins, thereby engaging and fixing the slots inside the connector plate, thus reinforcing and stabilizing the connector plate. A knob can be used to rotate the lever, which in turn causes the two pins to oscillate, moving the end faces of the pins away from the slots, thus facilitating the removal and disassembly of the connector plate.

[0020] The invention is further configured such that: the top of each of the two locking pins is provided with an adaptation groove, and both ends of the rotating rod are fixedly connected to push pins, which are respectively movably connected to the adaptation grooves through the push pins.

[0021] The above technical solution facilitates the movement of the push post within the adaptation groove at the top of the locking post when the rotating rod rotates, thereby causing the locking post to slide and making it easy to disassemble the plug-in plate.

[0022] On the other hand, a method for assembling a multi-head quick-connect air-type busbar trunking is provided, including the following steps: S1. First, connect the male plug bolt to one end of the conductive copper busbar inside the busbar trough, and install multiple female plugs on the other multiple ends of the conductive copper busbar. S2. Next, connect the two busbars that need to be connected to the plug-in female of the other busbar through the male plug-in on one end. S3. Next, the plug plates on both sides of the male connector are inserted along the inner wall of the protective frame, so that the limiting groove on the outer wall is pressed against the limiting spring inside the protective frame, and the protrusion on the inner wall of the limiting spring is embedded in the limiting groove, thereby enabling the plug plate to be pre-positioned and fixed. S4. Continue to push the plug plate so that it is locked onto the positioning block through the plug slots on both sides. The inner wall of the plug slot presses against the locking posts on both sides, causing them to slide on the positioning block and press the internal spring. When the slot corresponds to the locking post, the return elasticity of the compressed spring can make the end face of the locking post engage with the inside of the slot, thereby fixing the male plug and allowing the conductive copper busbars inside the two connected busbars to be energized through the internally compressed contact. S5. Finally, the protective frame slides inside the slide groove via the internal slide bar, and slides the protective frame to the position of the boss. The limiting spring is adjusted to slide on the limiting groove to position it in the moving position of the protective frame, thus protecting the contact position of the male and female plugs and realizing the quick connection operation of the multi-head busbar. The push post moves inside the adaptation groove set on the top of the clamp post, thereby driving the clamp post to slide. S6. When multiple busbar trunkings need to be disassembled and repaired later, first use the adjusting bolts to connect the threaded connection on the protective frame to press the pressure block, so that the sleeve can rotate on the positioning shaft, so that the rocker arm drives the limit spring on the end face to bend, so that the protrusion can move away from the limit groove on the plug plate. And the adjusting nut can be used to bend and adjust the limit spring on the rocker arm to a certain extent, so that it moves away from the limit groove, and slide the protective frame onto the plug frame. S7. Next, turn the knob to make the rotating rod rotate, which will cause the push pin at its end to move inside the adaptation groove set on the top of the locking pin, thereby causing the locking pin to slide and make the end face of the locking pin move away from the locking groove. S8. Finally, simply pull the male connector out of the female connector to complete the disassembly of the busbar trunking that needs maintenance.

[0023] The beneficial effects of this invention are as follows: 1. The present invention proposes a multi-head quick-connect air-type busbar trunking and its assembly method. By setting the conductive copper busbar inside the busbar trunking to a multi-head connection, multiple busbar trunkings can be connected and fixed in multiple directions according to requirements when multiple busbar trunkings are arranged and installed, thereby improving the flexibility of installation and avoiding the problem of low space utilization caused by traditional multiple busbar trunkings being led out and installed. 2. The multi-head quick-connect air-type busbar trunking and its assembly method proposed in this invention have a quick-release structure at the plug joint of the busbar trunking, so that the busbar trunking can be quickly locked and fixed by simply plugging the end face together during connection, which improves the convenience of installation and the stability during use, and also facilitates quick disassembly during subsequent inspection and maintenance.

[0026] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.

[0027] like Figures 1-3As shown, a multi-head quick-connect air-type busbar trunking and its assembly method include multiple conductive copper busbars 1. Multiple conductive terminals are symmetrically fixedly connected to the sidewalls of the multiple conductive copper busbars 1 near one end for transmitting multiple circuit currents and connecting multiple electrical devices. Multiple stabilizing frames 2 are respectively snapped onto the outer wall of the conductive copper busbars 1 for fixing the conductive copper busbars 1 during assembly. Each of the multiple stabilizing frames 2 has multiple ventilation slots 21, which are distributed alternately with the multiple conductive copper busbars 1 to facilitate the flow of high temperatures generated during use of the busbar trunking, thus facilitating heat dissipation. Two protective shells 3 are symmetrically snapped onto the sidewalls of the multiple conductive copper busbars 1. Mounting blocks 31 are symmetrically bolted to the end faces of both protective shells 3 for protecting the conductive copper busbars 1. Two heat dissipation side plates 4 are symmetrically bolted to the sidewalls of the protective shells 3, and each outer wall is provided with multiple heat dissipation fins 41 to cooperate with the protective shells 3 in protecting the internal conductive copper busbars 1.

[0028] like Figure 4 As shown, the male connector 5 is bolted to one end of the protective housing 3 and is used to connect and fix multiple busbar trunking sections that need to be connected. The male connector 5 includes a mounting plate 51 bolted to the mounting block 31. A boss 52 is provided in the middle of the side wall of the mounting plate 51. Plug-in plates 54 are symmetrically arranged on both sides of the boss 52. The two plug-in plates 54 are plugged into both sides of the female connector 6. Plug-in grooves 55 are opened in the middle of the end faces of the two plug-in plates 54. The mounting plate 51 is installed on the end face of the protective housing 3 so that the boss 52 can correspond to the end face of the plug-in bracket 61. The plug-in plates 54 facilitate the connection and fixation of the two busbar trunking sections when plugged in, and the plug-in grooves 55 facilitate the engagement and fixation of the plug-in bracket 61 and the plug-in plates 54.

[0029] like Figures 5-7 As shown, multiple female connectors 6 are respectively installed on the other end of the conductive copper busbar 1 and multiple conductive terminals, and are used to connect and fix the busbar trough that needs to be connected through male connectors 5. The female connector 6 includes a connector frame 61 bolted to the protective housing 3 and plugged into the conductive terminal. Multiple contacts 62 are evenly engaged and connected in the middle of the inner wall of the connector frame 61, and the contacts 62 are arranged in a Z-shape. The contacts 62 can be used to connect and energize the conductive copper busbar 1 inside the two plugged busbar troughs.

[0030] like Figure 8 and Figure 9As shown, a protective frame 63 is slidably connected to the outer wall of the plug-in bracket 61, and the protective frame 63 can protect and fix the contact position of the busbar trunking. Sliding strips 631 are symmetrically arranged at the inner top and bottom near the center of the protective frame 63, and are slidably connected to the sliding grooves 611 opened at the top and bottom near the center of the plug-in bracket 61 via the sliding strips 631. Simultaneously, they can slide into corresponding grooves 53 symmetrically opened at the top and bottom near the center of the boss 52, facilitating the sliding of the protective frame 63 on the plug-in bracket 61 and onto the boss 52, thus protecting the male and female plug-in connectors. The connection points of the protective frame 63 are sealed to prevent the entry of external dust. Positioning shafts 632 are symmetrically fixedly connected to the middle of the side wall of the protective frame 63 near the center. The outer walls of both positioning shafts 632 are rotatably connected to sleeves 633. Pressure blocks 634 are fixedly connected to the middle of the side walls of both sleeves 633. Adjusting bolts 636 are threaded through the pressure grooves 635 in the middle of the two pressure blocks 634 and threadedly connected to the side wall of the protective frame 63. A rocker arm 637 is fixedly connected to the middle of the side of each sleeve 633 away from the pressure block 634. The end faces of both rocker arms 637 are... The busbar is fitted with limiting springs 638. Each limiting spring 638 has a protrusion 6381 near its end face on its side wall. These protrusions 6381 engage with multiple limiting slots 57 on opposite walls of the two insertion plates 54. The end faces of both limiting springs 638 are inclined, and each has an adjustment slot 6382 in the middle. The protrusions 6381 on the side wall of the limiting spring 638 engage with the limiting slots 57 on the inserted insertion plate 54, improving the stability of the busbar connection. The adjustment slots 6382 facilitate the tightening of the lever 637, making it easier to adjust the connection. When the protrusion 6381 is away from the limiting groove 57, the end faces of the two rocker arms 637 are threaded with adjusting nuts 639, which are respectively pressed against the end faces of the limiting springs 638. The adjusting bolt 636 drives the pressure block 634 to rotate on the positioning shaft 632 through the sleeve 633 connected to the end face, so that the rocker arms 637 drive the limiting springs 638 on the end face to bend, thereby making the protrusion 6381 away from the limiting groove 57 on the plug plate 54, thus facilitating the disassembly of the busbar joint. The adjusting nuts 639 can be used to bend and adjust the limiting springs 638 by the rocker arms 637.

[0031] like Figures 10-12As shown, a locking assembly 64 is symmetrically bolted to the middle of the side wall of the plug-in bracket 61. The locking assembly 64 can further reinforce and stabilize the male plug-in connector 5 and the female plug-in connector 6, improving the stability of the busbar trunking during installation and use. The locking assembly 64 includes a positioning block 641. A rotating shaft 642 is rotatably connected to the middle of the side wall of the positioning block 641. A knob 643 is fixedly connected to the end face of the rotating shaft 642. A rotating rod 644 is fixedly connected to the end of the rotating shaft 642 away from the knob 643. The two ends of the rotating rod 644 are movably connected to locking pins 645. The two locking pins 645 pass through the side wall of the positioning block 641 and are slidably connected thereto. At the same time, the end faces of the two locking pins 645 can be locked into the locking groove 56 opened in the inner wall of the plug-in groove 55. The top of the two locking pins 645 is provided with an adaptation groove 6451. The two ends of the rotating rod 644 are fixedly connected to push pins 6441, and the push pins 6441 are respectively connected to the male plug-in connector 55. 6441 is movably connected to the adaptation groove 6451, so that when the rotating rod 644 rotates, it can drive the push post 6441 to move inside the adaptation groove 6451 set on the top of the locking post 645, thereby driving the locking post 645 to slide, which facilitates the disassembly of the plug-in plate 54. The opposite end faces of the two locking posts 645 are fixedly connected to the connecting posts 646. The outer walls of the two connecting posts 646 are fitted with springs 647, and the end faces of the springs 647 are pressed against the inner side wall of the positioning block 641. The internal springs 647 can elastically reset the squeezed locking posts 645, thereby locking and fixing the locking groove 56 inside the plug-in plate 54, thus reinforcing and stabilizing the plug-in plate 54. The knob 643 can drive the rotating rod 644 to rotate, which can make the two locking posts 645 fluctuate, so that the end faces of the locking posts 645 move away from the locking groove 56, thereby facilitating the extraction and disassembly of the plug-in plate 54.

[0032] like Figures 1-12 As shown, an assembly method for a multi-head quick-connect air-type busbar trunking includes the following steps: S1. First, connect the male plug 5 to one end of the conductive copper busbar 1 inside the busbar trough with a bolt, and install multiple female plugs 6 on the other multiple ends of the conductive copper busbar 1. S2. Next, connect the two busbars that need to be connected to the plug-in male connector 5 on one end of the other busbar through the plug-in female connector 6. S3. Next, the plug plates 54 on both sides of the male plug 5 are inserted along the inner wall of the protective frame 63, so that the limiting groove 57 provided on the outer wall is pressed against the limiting spring piece 638 inside the protective frame 63, so that the protrusion 6381 provided on the inner wall of the limiting spring piece 638 is embedded in the limiting groove 57, thereby enabling the plug plate 54 to be pre-positioned and fixed. S4. Next, continue to push the plug plate 54 so that it is locked onto the positioning block 641 through the plug slots 55 on both sides. The inner wall of the plug slot 55 presses against the locking posts 645 on both sides, causing them to slide on the positioning block 641 and press against the internal spring 647. When the slot 56 corresponds to the locking post 645, the return elasticity of the compressed spring 647 can make the end face of the locking post 645 engage with the inside of the slot 56, thereby fixing the plug male head 5. At the same time, the conductive copper busbar 1 inside the two connected busbar slots can be energized through the internally compressed contact 62. S5. Finally, the protective frame 63 is slid in the slide groove 611 through the internal slide bar 631, and the protective frame 63 is slid to the position of the boss 52. The limiting spring 638 is slid and adjusted on the limiting groove 57 to position it at the moving position of the protective frame 63, thus protecting the contact position of the plug male head 5 and the plug female head 6 and realizing the quick connection operation of the multi-head busbar. S6. When multiple busbar trunkings need to be disassembled and repaired later, the adjusting bolt 636 is first threaded onto the protective frame 63 to press the pressure block 634, so that the sleeve 633 can rotate on the positioning shaft 632, so that the rocker arm 637 drives the end face limit spring 638 to bend, so that the protrusion 6381 can move away from the limit groove 57 on the plug plate 54. The adjusting nut 639 can be used to bend and adjust the limit spring 638 by the rocker arm 637 to move it away from the limit groove 57, and slide the protective frame 63 onto the plug frame 61. S7. Next, rotate the knob 643 to drive the rotating rod 644 to rotate, which in turn causes the push post 6441 at its end to move inside the adaptation groove 6451 set on the top of the locking post 645, thereby causing the locking post 645 to slide, so that the end face of the locking post 645 moves away from the locking groove 56. S8. Finally, simply pull out the plugged busbar through the male connector 5 and then the female connector 6 to complete the disassembly operation of the busbar that needs maintenance.

[0033] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.

3. The multi-head quick-connect air-type busbar trunking according to claim 2, characterized in that: The inner wall of the plug-in bracket (61) is evenly connected with multiple contact elements (62), and the contact elements (62) are arranged in a Z-shape.

4. A multi-head quick-connect air-type busbar trunking according to claim 3, characterized in that: The protective frame (63) has symmetrically arranged slide bars (631) at the inner top and inner bottom near the middle position. The slide bars (631) are slidably connected to the slide grooves (611) opened at the top and bottom near the middle position of the plug frame (61). At the same time, they can slide into the corresponding grooves (53) symmetrically opened at the top and bottom near the middle position of the boss (52).

5. A multi-head quick-connect air-type busbar trunking according to claim 4, characterized in that: Both of the limiting springs (638) have inclined end faces and an adjustment groove (6382) in the middle.

6. A multi-head quick-connect air-type busbar trunking according to claim 5, characterized in that: The top of each of the two locking pins (645) is provided with an adaptation groove (6451), and both ends of the rotating rod (644) are fixedly connected with push pins (6441), and are respectively movably connected to the adaptation grooves (6451) through the push pins (6441).

7. The assembly method of a multi-head quick-connect air-type busbar trunking according to claim 6, characterized in that: Includes the following steps: S1. First, connect the male plug (5) to one end of the conductive copper busbar (1) inside the busbar trough with a bolt, and install multiple female plugs (6) on the other multiple ends of the conductive copper busbar (1); S2. Next, the two busbars that need to be connected are inserted into the plug-in female connector (6) of the other busbar through the plug-in male connector (5) set on one end. S3. Next, the plug plates (54) on both sides of the male plug (5) are inserted along the inner wall of the protective frame (63), so that the limiting groove (57) provided on the outer wall is pressed against the limiting spring (638) inside the protective frame (63), so that the protrusion (6381) provided on the inner wall of the limiting spring (638) is embedded in the limiting groove (57), thereby enabling the plug plate (54) to be pre-positioned and fixed. S4. Then, continue to push the plug plate (54) so ​​that it is locked onto the positioning block (641) through the plug slots (55) on both sides. The inner wall of the plug slot (55) presses the locking pins (645) on both sides, so that they slide on the positioning block (641) and press the internal spring (647). When the slot (56) corresponds to the locking pin (645), the return elasticity of the internal compressed spring (647) can make the end face of the locking pin (645) engage and connect to the inside of the slot (56), thereby fixing the plug male head (5) and allowing the conductive copper busbars (1) inside the two connected busbar slots to be energized through the internally compressed contact (62). S5. Finally, the protective frame (63) is slid in the slide groove (611) through the internal slide bar (631), and the protective frame (63) is slid to the position of the boss (52), and the limiting spring (638) is slid and adjusted on the limiting groove (57) to position it at the position where the protective frame (63) moves, so as to protect the contact position of the plug male (5) and plug female (6) and realize the quick connection operation of the multi-head busbar. S6. When multiple busbar trunkings need to be disassembled and repaired later, first use the adjusting bolt (636) to connect the threaded connection on the protective frame (63) to press the pressure block (634), so that the sleeve (633) can rotate on the positioning shaft (632), so that the rocker arm (637) drives the end face limit spring (638) to bend, so that the protrusion (6381) can move away from the limit groove (57) on the plug plate (54), and use the adjusting nut (639) to bend the limit spring (638) on the rocker arm (637) to make it move away from the limit groove (57), and slide the protective frame (63) onto the plug frame (61); S7. Next, rotate the knob (643) to drive the rotating rod (644) to rotate, which in turn drives the push post (6441) on its end face to move inside the adaptation groove (6451) set on the top of the locking post (645), thereby driving the locking post (645) to slide, so that the end face of the locking post (645) moves away from the locking groove (56). S8. Finally, simply pull out the plugged busbar through the male plug (5) and then pull out the female plug (6) to complete the disassembly of the busbar that needs maintenance.
