[0046] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0047] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0048] This utility model embodiment discloses a copper busbar connection device, as shown in the attached figure. Figure 1 As shown, it includes a first connector 1 and / or a second connector 2. The first connector 1 and the second connector 2 are arranged according to the reversing direction of the copper busbar 01. In a preferred embodiment, this utility model provides two sets of first connectors 1 and one set of second connectors 2, for... Figure 1 Using the coordinate system in the figure as a reference, the first connector 1 and the second connector 2 are respectively connected to the copper busbars 01 in different planes. The first connector 1 is used to connect two perpendicularly intersecting copper busbars 01 in the XOZ plane, and the second connector 2 is used to connect two perpendicularly intersecting copper busbars 01 in the XOY plane.

[0049] As attached Figure 2 As shown, the first connector 1 includes a first base 11 and two first pressure blocks 12. Two first slots 13 are laid flat inside the first base 11, and a copper busbar 01 can be inserted into each first slot 13. The center lines of the two first slots 13 intersect, and can be orthogonal or oblique, depending on the wiring method of the copper busbar 01 within the device. At least one first pressure block 12 is slidably disposed within each first slot 13. When a copper busbar 01 is inserted into a first slot 13, the first pressure block 12 presses and fixes the copper busbar 01 within the corresponding first slot 13, thus connecting the two copper busbars 01 with the first connector 1. To reliably press the copper busbar 01, two first pressure blocks 12 are preferably configured in each first slot 13. Of course, the number of first pressure blocks 12 can be adjusted according to the specifications of the copper busbar 01, and is not specifically limited here.

[0050] As attached Figure 3 As shown, the second connector 2 includes a second base 21 and two second pressure blocks 22. The second base 21 has two bent second slots 23, each capable of holding a copper busbar 01. The center lines of the two second slots 23 intersect, and can be orthogonal or oblique, depending on the wiring configuration of the copper busbars 01 within the device. Each second slot 23 has at least one sliding second pressure block 22. When a copper busbar 01 is inserted into a second slot 23, the second pressure block 22 presses and fixes the copper busbar 01 within the corresponding slot 23, thus connecting the two copper busbars 01 with the first connector 1. For reliable pressing of the copper busbars 01, two second pressure blocks 22 are preferably configured in each second slot 23. However, the number of second pressure blocks 22 can be adjusted according to the specifications of the copper busbars 01, and is not specifically limited here.

[0051] When two copper busbars 01 are inserted into the two first slots 13 respectively, the two first clamping blocks 12 fix the copper busbars 01 in the corresponding first slots 13, so that the first connector 1 connects the two copper busbars 01 in one plane. When two copper busbars 01 are inserted into the two second slots 23 respectively, the two second clamping blocks 22 fix the copper busbars 01 in the corresponding second slots 23, so that the second connector 2 connects the two copper busbars 01 in another plane. In this utility model, the first connector 1 and the second connector 2 adopt a modular design, which can flexibly adapt to the reversing connection requirements of copper busbars 01 with different spatial orientations. Installation can be completed quickly without bending or cutting the copper busbars 01 with special tools. The operation is more convenient and completely avoids the complicated processing procedures such as cutting and bending of copper busbars 01 in traditional processes, effectively shortening the installation cycle and improving installation efficiency.

[0052] As a preferred embodiment, as shown in the appendix Figure 4 and 5 As shown, the first base 11 includes a first base plate 111 and a first inner retaining edge 112 and a first outer retaining edge 113 respectively fixed on two opposite sides of the first base plate 111. The three are integrally formed, wherein the first inner retaining edge 112 is located on the inner side of the first base 11 and has the shortest length. The first base 11 is an L-shaped flat plate, so that the copper busbars 01 in the two first slots 13 are laid flat on the first base 11. Both the first inner retaining edge 112 and the first outer retaining edge 113 are L-shaped retaining edges, and each of the opposite ends of the first inner retaining edge 112 and the first outer retaining edge 113 forms a first slot 13. The center lines of the two first slots 13 intersect perpendicularly, so that the first connector 1 connects two mutually perpendicular copper busbars 01 in a plane.

[0053] As a preferred embodiment, as shown in the appendix Figure 5 As shown, the first outer retaining edge 113 has a segmented structure. The first outer retaining edge 113 includes two first outer retaining segments 1131 respectively located at both ends of the outer edge of the first base plate 111. A first notch 1132 is formed between the two first outer retaining segments 1131 to allow the copper busbar 01 to be inserted into one of the first slots 13. The first notch 1132 is located at the L-shaped corner 1111 of the first base plate 111. The copper busbar 01 can also be inserted into one of the slots at the first notch 1132, so that the first connector 1 can connect three copper busbars 01 at the same time, meet the reversing connection requirements of copper busbars 01 with different spatial orientations, and effectively improve adaptability.

[0054] As a preferred embodiment, as shown in the appendix Figure 2 As shown, the first inner edge 112 is a continuous structure. A first arc edge 1121 is formed at the corner of the first inner edge 112. The first arc edge 1121 is fixedly connected to the L-shaped corner 1111 to avoid the first inner edge 112 forming a protruding edge that scratches the copper busbar 01, which is beneficial to improving the connection quality.

[0055] As a preferred embodiment, as shown in the appendix Figure 2 , 4 As shown in Figure 5, the first connector 1 also includes a first connecting conductor 14 that fits against the first base plate 111. The first connecting conductor 14 is an L-shaped flat plate that perfectly matches the shape of the first base plate 111. The first connecting conductor 14 is used to connect the copper busbars 01 in the two first slots 13, so that the two copper busbars 01 in the first connector 1 are reliably connected through the first connecting conductor 14, avoiding poor contact between the two copper busbars 01 and causing poor circuit connection, thus improving connection reliability. It should be noted that both copper busbars 01 are pressed on the first connecting conductor 14. The first connecting conductor 14 can be made of copper. Based on this, the first base 11 and the first pressure block 12 can both be insulating parts to prevent leakage of current in the first connector 1 and cause safety accidents.

[0056] As a preferred embodiment, as shown in the appendix Figure 7 and 8 As shown, the second base 21 includes a second bent plate 211 and a second upper retaining edge 212 and a second lower retaining edge 213 respectively fixed on two opposite sides of the second bent plate 211. The second bent plate 211 is an L-shaped bent plate, that is, the second bent plate 211 is integrally connected by two mutually perpendicular flat plates. The second upper retaining edge 212 and the second lower retaining edge 213 are L-shaped retaining edges of equal length; each of the opposite ends of the second upper retaining edge 212 and the second lower retaining edge 213 forms a second slot 23, and the center lines of the two second slots 23 intersect perpendicularly, so that the second connector 2 connects to two mutually perpendicular copper busbars 01 in another plane.

[0057] As a preferred embodiment, as shown in the appendix Figure 3 , 7 As shown in Figure 8, the second connector 2 also includes a second connecting conductor 24 that fits against the second bent plate 211. The second connecting conductor 24 is an L-shaped bent plate that perfectly matches the shape of the second bent plate 211. The second connecting conductor 24 is used to connect the copper busbars 01 in the two second slots 23, ensuring a reliable connection between the two copper busbars 01 in the second connector 2. This prevents poor contact between the two copper busbars 01 and thus avoids poor circuit connection, further improving connection reliability. It should be noted that both copper busbars 01 are pressed onto the second connecting conductor 24. The second connecting conductor 24 can also be made of copper. Based on this, both the second base 21 and the second pressure block 22 can be insulating components to prevent leakage from the second connector 2 and potential safety accidents.

[0058] As a preferred embodiment, as shown in the appendix Figure 5 , 8 As shown in Figure 9, the first pressing block 12 and the second pressing block 22 have the same structure, both including a limiting plate X11, a fastener X12 and a pressing plate X13.

[0059] For the first pressing block 12, one side of the limiting plate X11 is fastened to the first inner snap-fit ​​edge 112 and the first outer snap-fit ​​edge 113 respectively. The limiting block limits the position of the first pressing block 12, providing reliable support for the fastener X12 to press against the pressing plate X13. For the second pressing block 22, one side of the limiting plate X11 is fastened to the second upper snap-fit ​​edge 212 and the second lower snap-fit ​​edge 213 respectively. The limiting block limits the position of the second pressing block 22, providing reliable support for the fastener X12 to press against the pressing plate X13.

[0060] Fastener X12 passes through limiting plate X11, specifically a bolt. Correspondingly, limiting plate X11 is provided in the through threaded hole, allowing limiting plate X11 and fastener X12 to be threadedly connected. Pressing plate X13 abuts against the end of fastener X12 that passes through limiting plate X11. Pressing plate X13 is used to press and fix copper busbar 01 through fastener X12, thereby fixing copper busbar 01 onto the first base plate 111 or the second curved plate 211, achieving reliable fixation of copper busbar 01. In other words, in this utility model, both the first pressing block 12 and the second pressing block 22 adopt a bolt-tightening structure, facilitating the disassembly and assembly of copper busbar 01 and reducing installation difficulty.

[0061] As a preferred embodiment, for the first pressing block 12, as shown in the attached figure Figure 2 As shown, both the first inner edge 112 and the first outer edge 113 are bent with L-shaped hooks on the side facing the limiting plate X11; for the second pressing block 22, as shown in the attached... Figure 3 As shown, the second upper buckle edge 212 and the second lower buckle edge 213 are both bent with L-shaped hooks on the side facing the limiting plate X11; correspondingly, the limiting plate X11 is provided with two limiting slots X111, each limiting slot X111 engaging with one of the L-shaped hooks, thereby relying on the limiting plate X11 to limit the position of the first pressing block 12 and / or the second pressing block 22, and facilitating disassembly and assembly, thus significantly improving installation efficiency.

[0062] As a preferred embodiment, as shown in the appendix Figure 9 As shown, the fastener X12 has a spherical protrusion X121 at one end that abuts against the pressing plate X13, and the pressing plate X13 has a spherical groove X131. The spherical protrusion X121 and the spherical groove X131 fit together to achieve self-adjustment, effectively compensate for the positional deviation of the copper busbar 01 during installation, and can automatically correct the pressing angle during the fastening process to ensure that the pressing block and the surface of the copper busbar 01 achieve full-area contact, avoid the edge stress concentration phenomenon caused by traditional planar contact, and reduce the risk of damage to the surface of the copper busbar 01.

[0063] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0064] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
