Copper busbar, also known as copper busbar, copper busbar or copper busbar, grounding copper busbar, is made of copper material, with a long conductor with a rectangular or chamfered (rounded) rectangular cross-section.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] Reference Figure 1-12 A spliced ​​high-current and high-voltage copper busbar comprises a main copper busbar 1, and installation sockets 2 are provided at both left and right ends of the main copper busbar 1. The main copper busbar 1 comprises a left copper busbar seat 100, a connecting copper busbar 101 and a right copper busbar seat 102. The upper right ends of the left copper busbar seat 100 and the connecting copper busbar 101 are provided with connecting slots 28. The upper left ends of the right copper busbar seat 102 and the connecting copper busbar 101 are connected with connecting sliders 29 matching the connecting slots 28. One side of the left copper busbar seat 100 and the right copper busbar seat 102 is provided with installation sockets 2, and the upper end of the connecting copper busbar 101 is provided with an installation slide groove 4. The main copper busbar 1 is assembled by splicing the left copper busbar seat 100, the connecting copper busbar 101 and the right copper busbar seat 102, so that they can be assembled according to the needs of use, and the copper busbar can be recycled.

[0035] The left and right ends of the main copper busbar 1 are both provided with rubber pads 3, and the front sides of the two rubber pads 3 are both provided with guide insulating sleeves 11 matching the mounting sockets 2, and the guide insulating sleeves 11 are evenly provided with rubber flaps 12 at one end away from the rubber pads 3, and the rubber flaps 12 are connected to the end away from the guide insulating sleeves 11 with an insulating pad 13, and the opposite side of the insulating pad 13 is provided with an anti-skid groove 14, and the main copper busbar 1 is insulated and separated from the distribution cabinet by the rubber pad 3. The main copper busbar 1 is conveniently installed in the distribution cabinet by connecting bolts through the setting of the mounting sockets 2, and the connecting bolts are insulated and protected by the guide insulating sleeves 11 and the insulating pads 13, and the anti-skid grooves 14 make it difficult for the connecting bolts to loosen after being locked.

[0036] A gasket 15 is embedded in the front mounting socket 2 of the main copper busbar 1. The gasket 15 is made of stainless steel. A positioning groove 16 matching the insulating pad 13 is provided on the upper surface of the gasket 15. By using the gasket 15 made of stainless steel, the connecting bolts can be prevented from loosening due to the ductility of the material of the main copper busbar 1. At the same time, the positioning groove 16 matching the insulating pad 13 can be provided to prevent the insulating pad 13 from rotating synchronously with the connecting bolts that are screwed.

[0037] The upper end of the main copper busbar 1 is evenly provided with mounting grooves 4, in which a conductive plate 5 is inserted, and the cross section of the mounting groove 4 is in a dovetail shape. The conductive plate 5 is composed of a tensioning frame 50 and a connecting plate 51 that match the mounting groove 4. The cross section of the tensioning frame 50 is in an open triangle shape. Through the sliding connection between the conductive plate 5 and the mounting groove 4, the conductive plate 5 is easy to install on the main copper busbar 1, and can be quickly assembled and installed according to the number of plug-in splints required during use.

[0038] The bending angle of the tensioning frame 50 is 1 to 2 degrees greater than the inner angle of the mounting slot 4. A chamfer is provided on the outer side of the lower end of the tensioning frame 50, and a guide slope is provided at the upper opening of the mounting slot 4. By adopting the setting that the bending angle of the tensioning frame 50 is greater than the inner angle of the mounting slot 4, the side walls of the tensioning frame 50 section of the conductive plate 5 respectively squeeze the inner side walls of the mounting slot 4, so that the conductive plate 5 is more stable and reliable after being plugged into the main copper bus 1, and at the same time, poor contact caused by too loose plugging between the conductive plate 5 and the mounting slot 4 on the main copper bus 1 is avoided. At the same time, the chamfer is provided on the outer side of the lower end of the tensioning frame 50 and the guide slope is provided at the upper opening of the mounting slot 4, so that the tensioning frame 50 part of the conductive plate 5 is easy to insert into the dovetail-shaped mounting slot 4.

[0039] The upper part of the conductive plate 5 is provided with a limit block 6 matching the installation slot 4, and the lower surface of the limit block 6 is provided with a tensioning strip 18 matching the tensioning frame 50. The main copper bar 1 is provided with a positioning slot 19 connected to the installation slot 4. A U-shaped mounting plate 20 is welded to one end of the conductive plate 5, and a plug rod 21 is inserted at the upper end of the U-shaped mounting plate 20. A wedge-shaped plug block 22 matching the positioning slot 19 is sleeved on the outer side of the middle part of the plug rod 21. A mounting hole is provided on one side of the plug rod 21, and a reset spring 23 is installed in the mounting hole. A spring 23 matching the wedge-shaped plug block 22 is provided on one side of the tensioning strip 18. The matching wedge-shaped pressure block 24 fixes the vertical position of the tensioning frame 50 of the conductive plate 5 through the limiting pressure block 6, and at the same time pushes the side wall of the tensioning frame 50 of the conductive plate 5 to fit tightly with the inner wall of the mounting slot 4 through the tensioning strip 18, further avoiding poor contact caused by loose connection between the tensioning frame 50 and the mounting slot 4 of the main copper bus 1, and at the same time drives the wedge-shaped pressure block 24 to squeeze the wedge-shaped plug block 22 through the tensioning strip 18, so that the reset spring 23 is compressed and deformed, and at the same time the wedge-shaped plug block 22 is inserted into the positioning groove 19, so that the position of the conductive plate 5 is positioned and fixed.

[0040] Fixed sleeves 7 are provided on both sides of the left and right sides of one end of the conductive plate 5 away from the mounting slide groove 4. The fixed sleeves 7 on one side are distributed in a herringbone shape. The fixed sleeves 7 are made of the same material as the conductive plate 5. The fixed sleeves 7 are welded and fixed to the conductive plate 5. Anti-slip strips 25 are evenly provided on the outside of the fixed sleeves 7. The cross-section of the anti-slip strips 25 is wedge-shaped. The conductive clamping plate 8 is positioned and fixed by the fixed sleeves 7. At the same time, the protective strips 25 prevent the conductive clamping plate 8 from falling off from the fixed sleeves 7.

[0041] A conductive clamping plate 8 is arranged between the fixing sleeves 7 on one adjacent side, and a connecting screw 9 is arranged on the side of the conductive clamping plate 8 away from the conductive plate 5. One end of the connecting screw 9 passes through the conductive clamping plate 8 and is threadedly connected to the fixing sleeve 7. The conductive clamping plate 8 is provided with a mounting through hole matching the fixing sleeve 7, and the side of the conductive clamping plate 8 away from the conductive plate 5 is provided with a mounting groove connected to the mounting through hole. An elastic washer 26 with a bowl-shaped cross section is arranged in the mounting groove, and a guide section with the same inner diameter as the elastic washer 26 is arranged on the outer side of the connecting screw 9. The elastic washer 26 is squeezed by the connecting screw 9 to make the conductive clamping plate 8 fit tightly with the conductive plate 5. At the same time, the directional force of the elastic washer 26 makes the connecting screw 9 not easy to loosen.

[0042] Limiting plates 10 are provided on both the upper and lower sides of the conductive clamping plate 8, and contact plates 17 are evenly pressed and provided on the conductive clamping plate 8. Rubber buffer strips are fixedly provided on the opposite sides of the two conductive clamping plates 8 away from one end of the conductive plate 5, and the side of the rubber buffer strip away from the conductive clamping plate 8 is parallel to the side of the contact plate 17. The setting of the limiting plates 10 allows the vertical upward position of the conductive plug and the plug copper busbar to be positioned and fixed after being plugged in. At the same time, the setting of multiple contact plates 17 on a single conductive clamping plate 8 allows multiple contact plates 17 to contact and conduct electricity with the conductive plug when the two conductive clamping plates 8 clamp and fix the conductive plug, thereby avoiding the poor conductivity of the conductive clamping plate caused by missing connection due to deformation of a single contact plate 17 under long-term use. At the same time, the conductive plug is limited in the lateral direction by the rubber buffer strip to avoid bending and deformation of the conductive clamping plate 8 due to left and right shaking of the conductive plug.

[0043] Working principle: During installation, the root connection bolts are respectively passed through the guide insulating sleeve 11 to connect and fix with the distribution cabinet, and the main copper bar 1 and the distribution cabinet are insulated by the rubber pad 3. At the same time, the guide insulating sleeve 11 and the insulating pad 13 are used to insulate the connection bolts to avoid leakage of the distribution cabinet caused by direct contact between the connection bolts and the main copper bar 1. At the same time, the compacted area of ​​the connection bolts is supported by a stainless steel gasket 15 to avoid deformation and loosening of the connection bolts after tightening due to the ductility of the material of the main copper bar 1. , the anti-skid groove 14 opened on the insulating pad 13 is used to prevent the connecting bolt from loosening after being locked, and then a certain number of conductive plates 5 are installed on the main copper busbar 1 according to the use needs, and the conductive plates 5 and the installation slide groove 4 are connected by sliding, so that the conductive plates 5 can be installed on the main copper busbar 1 more quickly, and the bending angle of the tension frame 50 of the conductive plate 5 is greater than the inner angle of the installation slide groove 4, and the toughness of the copper material of the conductive plate 5 is used to make the side walls of the tension frame 50 squeeze the installation slide groove respectively. 4, so that the conductive plate 5 is more stable and reliable after being plugged into the main copper bar 1, and at the same time, poor contact caused by the conductive plate 5 and the installation slot 4 on the main copper bar 1 being too loose is avoided. Then, the limiting pressure block 6 is installed in the installation slot 4, so that the limiting pressure block 6 fixes the vertical position of the tensioning frame 50 of the conductive plate 5, and at the same time, the tensioning strip 18 provided at the lower part of the limiting pressure block 6 is used to tighten the tensioning frame 50, so that the side wall of the tensioning frame 50 is closely fitted with the inner side wall of the installation slot 4, and further In order to further avoid poor contact caused by loose connection between the tension frame 50 and the installation slide groove 4 of the main copper busbar 1, the tension bar 18 is used to drive the wedge-shaped pressure block 24 to squeeze the wedge-shaped plug block 22, so that the reset spring 23 is compressed and deformed, and the wedge-shaped plug block 22 is inserted into the positioning groove 19, so that the position of the conductive plate 5 is positioned and fixed, and finally the connecting screw 9 is used to squeeze the elastic washer 26, so that the conductive clamping plate 8 and the conductive plate 5 are closely fitted, and the directional force of the elastic washer 26 is used to prevent the connecting screw 9 from loosening.

[0044] During operation, the conductive plug is inserted into the socket formed by two adjacent conductive splints 8, and conduction is achieved by fitting the contact plate 17 with the surface of the conductive plug. At the same time, a single conductive splint 8 is provided with multiple contact plates 17 to avoid deformation of a single contact plate 17 and poor conductivity of the conductive splint caused by missed connection under long-term use. At the same time, a rubber buffer strip is used to limit the conductive plug in the lateral direction to avoid bending and deformation of the conductive splint 8 due to the left and right shaking of the conductive plug, which causes changes in the distance between the two adjacent conductive splints 8, and the assembly contact plate 17 cannot fit with the surface of the conductive plug.

[0045] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
