[0056] Another technical problem to be solved by the present invention is an assembly method of a compact low-voltage busbar trunking,

[0057] S1. Overall assembly of the busbar trunking components: Assemble a plurality of groups of built-in plug plates into the busbar trunking housing, assemble a plurality of groups of insulating load-bearing columns on the built-in plug plates, assemble a plurality of groups of insulating load-bearing columns on the conductive copper bars, and enable the conductive copper bars to penetrate out of the busbar trunking housing, and assemble copper bar connection pieces on the conductive copper bars;

[0058] S2. Assembly of the first insertion member: Fit multiple groups of first connection gaskets onto multiple groups of copper bar connection pieces within one group of busbar groove members, so that the entire first insertion member is electrically connected to one group of busbar groove members;

Fit the first upper fastening frame and the second upper fastening frame to the upper end faces of the two groups of busbar housings respectively, and fit the first lower fastening frame and the second lower fastening frame to the lower end faces of the two groups of busbar housings respectively. Use the first fastening rod to position the first upper fastening frame and the first lower fastening frame, and use the second fastening rod to position the second upper fastening frame and the second lower fastening frame to further strengthen the connection between the two groups of busbar members. At the same time, the cover plate can be stably positioned on the busbar housing, and the cover plate can be re-positioned by screwing the first positioning screw and the second positioning screw into the insertion holes to prevent the connection between the conductive copper bars from becoming unstable due to shaking when the two groups of busbar members are spliced.

[0062] Generally speaking, compared with the prior art, the beneficial effects of the above technical solutions conceived by the present invention include:

[0063] The intensive low-voltage busbar trunking of the present invention and its assembly method. Through the arranged first insertion member and second insertion member, the first insertion member is pushed to move towards the second insertion member. When the first insertion frame penetrates into the second insertion frame, the roller moves upward along the lowest point of the displacement inclined plane, and the first compression spring can be compressed. When the first insertion frame continues to slide in the second insertion frame, the first insertion frame reaches the highest point of the displacement inclined plane and slides on the locking base. When the roller reaches the through-locking hole, the roller and the second displacement rod penetrate into the through-locking hole. After the roller penetrates into the through-locking hole, the built-in clamping plate is pushed, and the built-in clamping plate can cooperate with the first inclined plate and the second inclined plate to perform internal clamping operation on the first conduction column, so that the two busbar trunking components can be quickly spliced together. It can effectively prevent the conductive copper bars inside the two busbar trunking components from falling off after splicing due to vibration during the splicing of the two busbar trunking components, resulting in the situation of power failure, and greatly enhances the stability during the copper bar splicing. Through the arranged fastening member, the second adjusting plate is stretched out from the first adjusting plate, and the pin is used to insert and position the first adjusting plate and the second adjusting plate. The first upper fastening frame and the second upper fastening frame are respectively attached to the upper end faces of the two busbar trunking housings, and the first lower fastening frame and the second lower fastening frame are respectively attached to the lower end faces of the two busbar trunking housings. The first fastening rod is used to position the first upper fastening frame and the first lower fastening frame, and the second fastening rod is used to position the second upper fastening frame and the second lower fastening frame to further strengthen the connection between the two busbar trunking components. At the same time, the cover plate can be stably positioned on the busbar trunking housing, and the cover plate can be re-positioned by screwing the first positioning screw and the second positioning screw into the insertion hole to prevent the connection between the conductive copper bars from becoming unstable due to shaking during the splicing of the two busbar trunking components.

[0088] In some embodiments, more specifically, in order to enable the first conduction post 22 to be more tightly connected when connected to the second conduction post 32, a circular groove is provided at one end of the second conduction post 32 close to the first conduction post 22, and the circular groove can be penetrated by the first conduction post 22. When the first conduction post 22 penetrates into the circular groove, the first conduction post 22 is positioned within the second conduction post 32.

[0089] In some embodiments, in order to enable the first inclined plate 39, the second inclined plate 391, and the built-in clamping plate 38 to better abut and protect the first conduction post 22, there is a first included angle between the first inclined plate 39 and the built-in clamping plate 38, and a second included angle between the second inclined plate 391 and the built-in clamping plate 38. The values of the first included angle and the second included angle are the same.

A first insulating rubber pad is detachably installed on one side surface of the first inclined plate 39, and a second insulating rubber pad is detachably installed on one side surface of the second inclined plate 391.

[0090] Next, a more specific structure and configuration are given to the fastening member 4 for further explanation.

[0091] Next, a further explanation of the overall principle of use of the fastening member 4 will be given. First, the second adjusting plate 492 is extended from the first adjusting plate 45, and the pin 491 is used to insert and position the first adjusting plate 45 and the second adjusting plate 492. The first upper fastening frame 41 and the second upper fastening frame 46 are respectively attached to the upper end faces of the two busbar housing 11, and the first lower fastening frame 42 and the second lower fastening frame 47 are respectively attached to the lower end faces of the two busbar housing 11. The first fastening rod 43 is used to position the first upper fastening frame 41 and the first lower fastening frame 42, and the second fastening rod 48 is used to position the second upper fastening frame 46 and the second lower fastening frame 47, so as to further strengthen the connection between the two busbar members 1. At the same time, the cover plate 16 can be stably positioned on the busbar housing 11, and the first positioning screw 44 and the second positioning screw 49 can be screwed into the insertion hole 17 to re-position the cover plate 16, so as to prevent the connection between the conductive copper bars 14 from becoming unstable due to shaking when the two busbar members 1 are spliced.

[0092] In some embodiments, in order to further lock and protect the insertion hole 17, the size of the first positioning screw 44 is adapted to the size of the first upper fastening frame 41, and the first positioning screw 44 can penetrate into the insertion hole 17. The size of the second positioning screw 49 is adapted to the size of the second upper fastening frame 46, and the second positioning screw 49 can penetrate into the insertion hole 17.

[0093] Another technical problem solved by the present invention is an assembly method of a compact low-voltage busbar.

[0094] S1. Assembly of the overall busbar member 1: Assemble multiple groups of built-in insertion plates 12 into the busbar housing 11, assemble multiple groups of insulating bearing columns 13 on the built-in insertion plates 12, assemble multiple groups of insulating bearing columns 13 on the conductive copper bars 14, and make the conductive copper bars 14 pass through the busbar housing 11, and assemble the copper bar connecting pieces 15 on the conductive copper bars 14;

[0095] S2. Assembly of the first insertion member 2: Attach multiple groups of first connection gaskets 24 to multiple groups of copper bar connecting pieces 15 in one of the busbar members 1, so that the first insertion member 2 is electrically connected to one of the busbar members 1 as a whole;

[0096] S3. Assembly of the second insertion member 3: Attach multiple groups of second connection gaskets 33 to multiple groups of copper bar connecting pieces 15 in the other busbar member 1, so that the second insertion member 3 is electrically connected to the other busbar member 1 as a whole;

[0097] S4. Assembly and connection of the first interpenetrating member 2 and the second interpenetrating member 3: Push the first interpenetrating frame 21 towards the second interpenetrating frame 31. When the first interpenetrating frame 21 penetrates into the second interpenetrating frame 31, the roller 29 moves upward along the lowest point of the displacement inclined plane 37, and the first compression spring 294 can be compressed. When the first interpenetrating frame 21 continues to slide inside the second interpenetrating frame 31, the first interpenetrating frame 21 reaches the highest point of the displacement inclined plane 37 and slides on the locking base 34. When the roller 29 reaches the through locking hole 35, the roller 29 and the second displacement rod 27 penetrate into the through locking hole 35. After the roller 29 penetrates into the through locking hole 35, it pushes the built-in clamping plate 38, and the built-in clamping plate 38 can cooperate with the first inclined plate 39 and the second inclined plate 391 to perform an internal clamping operation on the first conduction column 22, effectively connecting the second conduction column 32 with the first conduction column 22, preventing the second conduction column 32 and the first conduction column 22 from falling off during vibration, and at the same time performing a lateral internal clamping operation on the first conduction column 22 to further strengthen the connection between the first conduction column 22 and the second conduction column 32.

[0098] S5. Assembly and use of the fastening member 4 as a whole: First, pull out the second adjusting plate 492 from the first adjusting plate 45, and the pin 491 is used to insert and position the first adjusting plate 45 and the second adjusting plate 492. The first upper fastening frame 41 and the second upper fastening frame 46 are respectively attached to the upper end faces of the two busbar housings 11, and the first lower fastening frame 42 and the second lower fastening frame 47 are respectively attached to the lower end faces of the two busbar housings 11. The first fastening rod 43 is used to position the first upper fastening frame 41 and the first lower fastening frame 42, and the second fastening rod 48 is used to position the second upper fastening frame 46 and the second lower fastening frame 47 to further strengthen the connection between the two busbar members 1. At the same time, the cover plate 16 can be stably positioned on the busbar housing 11, and the first positioning screw 44 and the second positioning screw 49 can be inserted into the through hole 17 to re-position the cover plate 16 to prevent the connection between the conductive copper bars 14 from becoming unstable due to shaking when the two busbar members 1 are spliced.

[0099] In summary, by arranging the first interpenetrating member 2 and the second interpenetrating member 3, the first interpenetrating member 2 is pushed to move towards the second interpenetrating member 3. When the first interpenetrating frame 21 penetrates into the second interpenetrating frame 31, the roller 29 moves upward along the lowest point of the displacement inclined plane 37, and the first compression spring 294 can be compressed. When the first interpenetrating frame 21 continues to slide in the second interpenetrating frame 31, the first interpenetrating frame 21 reaches the highest point of the displacement inclined plane 37 and slides on the locking base 34. When the roller 29 reaches the through locking hole 35, the roller 29 and the second displacement rod 27 penetrate into the through locking hole 35. After the roller 29 penetrates into the through locking hole 35, the built-in clamping plate 38 is pushed, and the built-in clamping plate 38 can cooperate with the first inclined plate 39 and the second inclined plate 391 to perform internal clamping on the first conduction column 22, so that the two busbar components 1 can be quickly spliced together. It can effectively prevent the conductive copper bars inside the two busbar components 1 from falling off after splicing due to vibration during the splicing of the two busbar components 1, resulting in a situation where power cannot be supplied, greatly enhancing the stability during copper bar splicing. By arranging the fastening member 4, the second adjusting plate 492 is stretched out from the first adjusting plate 45, and the pin 491 is used to insert and position the first adjusting plate 45 and the second adjusting plate 492. The first upper fastening frame 41 and the second upper fastening frame 46 are respectively attached to the upper end surfaces of the two busbar housings 11, and the first lower fastening frame 42 and the second lower fastening frame 47 are respectively attached to the lower end surfaces of the two busbar housings 11. The first fastening rod 43 is used to position the first upper fastening frame 41 and the first lower fastening frame 42, and the second fastening rod 48 is used to position the second upper fastening frame 46 and the second lower fastening frame 47 to further strengthen the connection between the two busbar components 1. At the same time, the cover plate 16 can be stably positioned on the busbar housing 11, and the first positioning screw 44 and the second positioning screw 49 can be screwed into the through hole 17 to re-position the cover plate 16 to prevent the connection between the conductive copper bars 14 from becoming unstable due to shaking during the splicing of the two busbar components 1.
