Description

Technical Field

[0001] This application relates to the technical field of inverter switches, and more particularly to a copper busbar connection structure for a household energy storage inverter liquid magnetic switch. Background Technology

[0002] The current external wiring terminal structure of the inverter is designed with a switch connected to a copper busbar, and the copper busbar is then connected to a terminal block, i.e., the layout of switch → copper busbar → terminal block.

[0003] However, while this design can achieve electrical connection, the copper busbar needs to maintain a certain bending radius and safety distance. At the same time, the switch, copper busbar, and terminal block are arranged sequentially along the length of the chassis, resulting in the wiring area occupying a large space. This requires an increase in the overall length of the chassis. As a result, this layout design requires a larger chassis length to accommodate the layout of related components. However, in some installation sites with limited space, the inverter may not be able to fit standard mounting brackets or reserved space due to its excessive length, resulting in additional adjustments to the installation plan on site, or even making installation impossible.

[0004] Therefore, there is an urgent need for a simpler wiring structure that can reduce the size of the product to solve this technical problem.

[0005] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is prior art. Utility Model Content

[0006] The main purpose of this application is to provide a copper busbar connection structure for a liquid magnetic switch in a household inverter, which aims to solve the problems that the existing internal switch layout of the inverter requires the addition of a terminal box, resulting in an increased overall housing size and inconvenience for installation.

[0007] To achieve the above objectives, this application provides a copper busbar connection structure for a liquid magnetic switch of a household energy storage inverter, including a switch and a copper busbar. The output end of the switch is connected to the copper busbar. The copper busbar includes a first copper busbar and a second copper busbar. Both ends of the second copper busbar are respectively provided with bending structures, wherein one of the bending structures is connected to the first copper busbar.

[0008] The first copper busbar and the second copper busbar are provided with wiring holes, and the wiring holes are connected to wire lugs by fasteners.

[0009] As a preferred embodiment of this application, the wiring hole includes a first wiring hole and a second wiring hole. The first wiring hole is provided on the side of the first copper busbar away from the switch, and the second wiring hole is provided on the end of the second copper busbar away from the first copper busbar.

[0010] As a preferred embodiment of this application, the first wiring hole and the second wiring hole are arranged in a staggered manner.

[0011] As a preferred embodiment of this application, it further includes a limiting block, which is disposed on both sides of the wiring hole and is bent toward the wire lug.

[0012] As a preferred embodiment of this application, the bending structure includes a first bending portion and a second bending portion, wherein the bending directions of the first bending portion and the second bending portion are opposite.

[0013] As a preferred embodiment of this application, the fastener includes a bolt and a nut, wherein the threaded portion of the bolt passes through the lug, the wiring hole and the nut in sequence.

[0014] This application provides a copper busbar connection structure for a liquid magnetic switch in a home energy storage inverter. The connection to the switch is achieved using a first copper busbar and a second copper busbar. A bending structure is set on the second copper busbar, and the first and second copper busbars are connected through the bending structure. This allows for a staggered layout, either vertically or horizontally, avoiding the waste of lateral space in traditional parallel arrangements. The wire lugs are directly connected through wiring holes and fasteners, eliminating the need for the transition structure of traditional terminal blocks. This allows for a reduction in the size of the inverter housing, making the inverter easier to install while also saving on housing manufacturing costs. Attached Figure Description

[0021] Furthermore, descriptions using terms such as "first" and "second" in this application are for descriptive purposes only (e.g., to distinguish identical or similar elements) and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, technical solutions from different embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If a combination of technical solutions is contradictory or impossible to implement, such a combination should be considered nonexistent and not within the scope of protection claimed in this application.

[0022] Please refer to Figure 1 , Figure 2 , Figure 3 In one embodiment, a copper busbar connection structure for a household storage inverter liquid magnetic switch 1 includes a switch 1 and a copper busbar. The output end of the switch 1 is connected to the copper busbar, which includes a first copper busbar 2 and a second copper busbar 3. Both ends of the second copper busbar 3 are respectively provided with bending structures 9, one of which is connected to the first copper busbar 2.

[0023] The first copper busbar 2 and the second copper busbar 3 are provided with wiring holes. The wiring holes are connected to wire lugs 6 through fasteners 7. Fasteners 7 can be self-tapping screws. Using self-tapping screws to penetrate the copper busbar and lock it to the wire lugs 6 is low-cost and does not require pre-embedded parts.

[0024] Specifically, based on the above embodiments, the wiring hole includes a first wiring hole 4 and a second wiring hole 5. The first wiring hole 4 is provided on the side of the first copper busbar 2 away from the switch 1, and the second wiring hole 5 is provided on the end of the second copper busbar 3 away from the first copper busbar 2.

[0025] It is understood that this application uses the first copper busbar 2 and the second copper busbar 3 to connect with the switch 1. A bending structure 9 is set on the second copper busbar 3, and the first copper busbar 2 and the second copper busbar 3 are connected by the bending structure 9. This can achieve a staggered layout, avoiding the waste of horizontal space in the traditional parallel arrangement. The wire lugs 6 are directly connected through the wiring holes and fasteners 7, eliminating the transition structure of the traditional terminal block. This allows the size of the inverter housing 10 to be reduced, making the inverter easy to install while also saving the cost of manufacturing the housing 10.

[0026] Specifically, please refer to Figure 3 Based on the above embodiment, the first wiring hole 4 and the second wiring hole 5 are arranged in a staggered manner.

[0027] It is understandable that when operators are assembling or disassembling the cable lug 6, the staggered design provides clearer visual distinction and prevents misoperation. At the same time, the staggered design allows the cables connected to the cable lug 6 to be led out at different angles (such as one going up and one going down), avoiding the concentration and crowding of the cable bundle and simplifying the wiring inside the housing 10.

[0028] Specifically, please refer to Figure 2 , Figure 3 Based on the above embodiments, a limiting block 8 is also included. The limiting block 8 is located on both sides of the wiring hole, and the limiting block 8 is bent in the direction close to the wire lug 6.

[0029] It is understandable that the limit block 8 is set to prevent the wire lug 6 from swinging left and right during the wiring process or normal use of the product, which may cause adverse factors and effects.

[0030] Specifically, please refer to Figure 2 Based on the above embodiments, the bending structure 9 includes a first bending portion and a second bending portion. The bending directions of the first bending portion and the second bending portion are opposite. Preferably, the first bending portion and the second bending portion are respectively bent at ninety degrees in opposite directions.

[0031] Preferably, based on the above embodiments, the fastener 7 includes a bolt and a nut, with the threaded portion of the bolt passing through the lug 6, the wiring hole, and connecting to the nut in sequence.

[0032] It is understandable that using bolts and nuts for fastening facilitates maintenance and disassembly, and is also relatively simple to install.

[0033] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, apparatus, article, or method that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, apparatus, article, or method. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, apparatus, article, or method that includes that element.

[0034] The above description is only a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural changes made based on the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
