Description

Technical Field

[0001] This utility model relates to the field of copper busbar technology, and in particular to a high current shunting surface-insulated welded soft copper busbar structure. Background Technology

[0002] Copper busbars are rectangular or irregularly shaped conductive materials made of high-purity electrolytic copper (copper content ≥99.9%), widely used in power, electronics, industrial control, and new energy fields. Their core function is as a high-current transmission carrier, and thanks to their high conductivity, low resistance, and good mechanical properties, they have become an indispensable key component in electrical systems.

[0003] Currently, copper busbars are widely used in outdoor energy storage, home energy storage, substations, servers, and other equipment to connect power supply components and power receiving components. In existing technology, the main structure of a copper busbar includes a main body, an input pole, and an output pole. The input pole and output pole are integrally formed and connected to both ends of the main body. In use, the input pole and output pole are fixedly connected to the power supply component and the power receiving component, respectively, and are electrically connected.

[0004] However, in the existing technology, both the input and output poles are rigidly connected to the main body, resulting in limited deformability and an inability to accommodate assembly errors. This makes it difficult to connect the copper busbar to external installations, and it is also prone to breakage under vibration conditions, adversely affecting conductivity. Furthermore, there is only one output pole, which cannot meet the requirements for shunt power transmission. Therefore, it is necessary to improve the current copper busbar. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies of the existing technology, and its main purpose is to provide a high-current shunting surface-insulated welded soft copper busbar structure, which can effectively solve the problems of existing copper busbars being difficult to connect to external installations, easily breaking under vibration conditions, and failing to meet the requirements of shunting power transmission.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-current shunt surface-insulated welded soft copper busbar structure includes a conductive body and an insulating block. The conductive body includes a substrate portion, a first flexible connection portion, two second flexible connection portions, an input electrode, and two output electrodes. The substrate portion is horizontally arranged. The first flexible connection portion and the two second flexible connection portions are integrally bent and extended from the edge of the substrate portion, and the first flexible connection portion and the two second flexible connection portions are separately arranged from each other. The input electrode is integrally formed and connected to the tail end of the first flexible connection portion. The two output electrodes are respectively integrally formed and connected to the tail ends of the two second flexible connection portions. The insulating block is formed and fixed on the surface of the substrate portion, and the insulating block completely covers the surface of the substrate portion.

[0008] As a preferred embodiment, the conductive body is formed by stacking and welding multiple copper foils. Copper foils have excellent flexibility, which better enables soft connections.

[0009] As a preferred embodiment, the thickness of the copper foil is 0.1 mm.

[0010] As a preferred embodiment, the first flexible connection portion is located on one side of the substrate portion, and the two second flexible connection portions are located on the other side of the substrate portion and are disposed separately to facilitate assembly.

[0011] As a preferred embodiment, the input electrode is plate-shaped and vertically arranged, and the two output electrodes are both plate-shaped and horizontally arranged, with the two output electrodes arranged parallel to each other and separated.

[0012] As a preferred embodiment, the input electrode has a first fixing hole and the output electrode has a second fixing hole, so that bolts can be used for installation and connection, making disassembly and assembly simple.

[0013] As a preferred embodiment, the insulating block is made of epoxy resin and has a resistance of 500MΩ, exhibiting good insulation and withstand voltage performance.

[0014] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0015] Through the first and second flexible connecting parts, the input and output poles can be flexibly connected to the outside. The flexible connecting parts can provide sufficient deformation to fully meet the assembly error, making it easier to connect the copper busbar to the outside. At the same time, it can effectively prevent breakage under vibration conditions, prevent failure, and make the conductive connection more stable and reliable. In addition, there are two output poles, which can meet the requirements of shunt power transmission. Furthermore, by setting an insulating block, insulation withstand voltage can be achieved to prevent electrical failure and bring convenience to use.

[0026] Please refer to Figures 1 to 3 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, including a conductive body 10 and an insulating block 20.

[0027] The conductive body 10 includes a substrate portion 11, a first flexible connection portion 12, two second flexible connection portions 13, an input electrode 14, and two output electrodes 15. The substrate portion 11 is horizontally disposed. The first flexible connection portion 12 and the two second flexible connection portions 13 are integrally bent and extended from the edge of the substrate portion 11, and are separately disposed from each other. The input electrode 14 is integrally formed and connected to the tail end of the first flexible connection portion 12. The two output electrodes 15 are integrally formed and connected to the tail ends of the two second flexible connection portions 13, respectively. In this embodiment, the conductive body 10 is formed by laminating and welding multiple copper foils 101. The copper foils 101 have good flexibility, which better realizes the soft connection. The thickness of the copper foils 101 is 0.1 mm. The substrate portion 11 is rectangular. The first flexible connection portion 12 is located on one side of the substrate portion 11, and the two second flexible connection portions 13 are located on the other side of the substrate portion 11 and are separately disposed. The input electrode 14 is plate-shaped and vertically arranged, and is square. The two output electrodes 15 are both plate-shaped and horizontally arranged, parallel to each other, and are square. The input electrode 14 has multiple first fixing holes 141 arranged in a row; in this embodiment, there are four, but not limited to one. Each first fixing hole 141 is a strip-shaped hole for easy alignment and installation. The output electrode 15 has multiple second fixing holes 151, each of which is a round hole, but not limited to one.

[0028] The insulating block 20 is molded and fixed to the surface of the substrate portion 11, completely covering the surface of the substrate portion 11. In this embodiment, the insulating block 20 is made of epoxy resin, and its resistance is 500MΩ, exhibiting good insulation withstand voltage performance. Furthermore, the insulating block 20 has a rectangular plate-like structure.

[0029] The usage method of this embodiment is described in detail below:

[0030] This product is suitable for circuit connections in outdoor energy storage, home energy storage, transformer cabinets, servers, and other equipment. During use, the insulating block 20 is positioned against the equipment to prevent short circuits. Then, a first bolt (not shown) is passed through the first fixing hole 141 and fixed to the output terminal of the power supply component, thus establishing a conductive connection between the input electrode 14 and the output terminal of the power supply component. Similarly, multiple second bolts (not shown) are passed through the second fixing holes 151 and fixed to the input terminals of multiple power receiving components, thus establishing a conductive connection between the two output electrodes 15 and the input terminals of two power supply components. During energized use, when the positions of the power supply and power receiving components change under vibration conditions, the first flexible connection part 12 and the two second flexible connection parts 13 provide flexible deformation space, ensuring that the conductive connection remains stable and reliable.

[0031] The key design features of this invention are: through the first and second flexible connecting parts, the input and output poles can be flexibly connected to the outside. The flexible connecting parts provide sufficient deformation to fully meet assembly tolerances, making it easier to connect the copper busbar to the outside and effectively preventing breakage under vibration conditions, thus preventing failure and making the conductive connection more stable and reliable. Furthermore, the two output poles can meet the requirements of shunt power transmission. In addition, by setting an insulating block, insulation withstand voltage is achieved to prevent electrical failure and bring convenience to use.
