Description

Technical Field

[0001] The present application relates to the technical field of fuse boxes, in particular to a fuse box, and further to an energy storage system including the fuse box. Background Art

[0002] A fuse, also known as a fuse or a fuse cutout, is a component connected in series in a circuit to ensure safe operation. It is widely used in power distribution and control systems, primarily for overcurrent protection. Its operating principle generally utilizes the thermal melting properties of metal. When the current rises abnormally high or reaches a certain temperature, it melts and cuts off the current, thereby protecting the circuit. A fuse block is a component that houses the fuse and conducts electricity. It is widely used in live equipment in photovoltaic, energy storage, automotive, and other fields.

[0003] The copper busbars that secure fuse boxes are typically fixed using an insert molding method. This involves pre-embedding the busbar in the mold before the plastic part is injection-molded. High-temperature fluid injection molding then wraps around the center of the busbar, securing it and ensuring electrical connection. However, this molding method places high demands on the dimensional tolerances of the busbar. According to mold flow analysis, tolerances must be kept within a range of -0.03-0.01mm, otherwise there is a risk of glue overflow or assembly failure. Furthermore, insert molding can significantly damage the mold and easily form cracks and visible weld marks around the busbar, significantly impacting its strength. This also complicates processing and equipment commissioning. Utility Model Content

[0037] To make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the specific technical solutions of the present application will be further described in detail below in conjunction with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application but are not intended to limit the scope of the present application.

[0038] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of this application, unless otherwise specified, "multiple" means two or more.

[0039] In addition, in the embodiments of the present application, directional terms such as "up", "down", "left" and "right" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they may change accordingly according to changes in the orientation of the components in the drawings.

[0040] In the embodiments of the present application, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integrated connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0041] In the embodiments of the present application, the terms "comprises," "comprising," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of other identical elements in the process, method, article, or apparatus comprising the element.

[0042] In the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be interpreted as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0043] In the prior art, the copper busbar inside the fuse box is generally manufactured using an inlay molding method. Therefore, the copper busbar is generally embedded in the mold before injection molding, and the middle portion of the copper busbar is wrapped with a high-temperature fluid to achieve the effect of fixing the copper busbar and electrically connecting it. However, this type of molding method requires high dimensional accuracy for the copper busbar. When the dimensional tolerance does not meet the requirements, there is a risk of glue overflow and assembly failure. In addition, this type of molding method causes significant damage to the mold, which shortens the mold life. Cracks and obvious weld marks are easily formed around the copper busbar, which adversely affects its strength. Therefore, this type of molding method has high precision and process requirements and is difficult to process. Moreover, since the copper busbar and the fuse box are an integrated structure, it is not convenient to assemble, disassemble, and replace during use, which makes it difficult to meet user needs.

[0044] Figure 1 It is a three-dimensional schematic diagram of a fuse box according to an embodiment of the present application, and includes: a box body 1 with an accommodating space formed therein and configured to have multiple openings 2 passing through one side thereof, a fuse element 3 arranged in the accommodating space and configured so that the terminal 31 corresponds one-to-one with the opening 2, and a conductive member 5 configured to pass through the inside of each opening 2 and be detachably connected to the box body 1 through a locking member 6, one end of the conductive member 5 passes through the box body 1 and is electrically connected to the terminal 31, and the other end passes through the opening 2 and is placed outside the box body 1; the locking member 6 is sequentially connected to the box body 1, the conductive member 5 and the terminal 31 of the fuse element 3 to fix the three.

[0045] In this arrangement, reference Figures 1 to 6 The fuse box described in this article is provided with multiple openings 2, which are convenient for connecting the conductive component 5 to the inside of the opening 2, one end of which is electrically connected to the terminal 31 of the fuse element 3 located inside the accommodating space, and the other end passes through the opening 2 to facilitate connection with external devices; thereby, the locking component 6 is used to realize the detachable connection between the conductive component 5 and the box body 1, while ensuring the function and strength of the fuse box, effectively avoiding the risk of breakage and mold damage caused by insert injection molding, thereby greatly reducing the processing difficulty of the fuse box, and also reducing the dimensional tolerance and other installation accuracy requirements of the conductive component 5; the locking component 6 is connected to the box body 1, the conductive component 5 and the terminal 31 of the fuse element 3, and a single component is used to achieve synchronous fixation and positioning of the three, which is convenient for installation and saves materials, and the detachable installation method also makes it convenient for users to disassemble and replace the conductive component 5 and the fuse element 3, which can meet the user's usage needs.

[0046] It should be noted that the above-mentioned fuse element 3 can be a fuse with two terminal terminals 31. By utilizing the thermal melting characteristics of metal, when the current abnormally rises to a certain height and temperature, it melts itself and cuts off the current, thereby protecting the circuit and achieving safe operation.

[0047] The following will introduce further specific implementation or refinement and improvement process of the fuse box through exemplary descriptions, so as to further improve it or for improvement considerations in other aspects.

[0048] For further reference, Figures 1 to 4 , further comprising: a positioning member 4 configured to be arranged correspondingly on the periphery of each opening 2 away from the fuse element 3, and a through opening 41 is provided inside the positioning member 4 opposite to the opening 2 for the conductive member 5 to pass through.

[0049] In this arrangement, the positioning member 4 is arranged outside the opening 2 and facilitates the insertion and positioning of the auxiliary conductive member 5 through the internal through-hole 41 opposite to the opening 2, so that the conductive member 5 is placed more stably during use.

[0050] Further, refer to Figures 1 to 4 The positioning member 4 is configured to be integrally formed with the box body 1 , and the cross-sectional shape of the through opening 41 is the same as that of the opening 2 .

[0051] It is not difficult to see that the positioning member 4 is integrally formed with the box body 1 , and the cross-sectional shape of the through-port 41 is the same as that of the opening 2 , so that the through-port 41 and the opening 2 are connected during molding, thereby adapting to the conductive member 5 of corresponding size.

[0052] Exemplarily, the cross-sectional shape of the through-portion 41 can be set to a rectangle, and the overall size can be slightly larger than the conductive component 5 to facilitate its connection and installation. Of course, the cross-sectional shape of the through-portion 41 can also be other shapes, such as circular, triangular or trapezoidal, etc., which can be selected according to the shape requirements of the conductive component 5 to match it. This embodiment does not make specific limitations here.

[0053] Exemplarily, the shape of the positioning member 4 can be a rectangular parallelepiped, but is not limited thereto. It can also be other shapes, such as cylindrical, triangular prism, etc. The positioning member 4 and the box body 1 can be formed by integrally processing a block of material, or can be formed by 3D printing. Regarding the specific molding method, this embodiment does not make any specific restrictions here.

[0054] In one case of this embodiment, one of the top cover 11 of the box body 1 and the insertion end of the conductive component 5 is provided with a threaded hole, and the other is provided with a light hole, and the three are fixed by a locking component 6 that is connected to the threaded hole, the light hole and the terminal 31.

[0055] It can be seen that by providing threaded holes and light holes in the top cover 11 of the box body 1 and the end of the conductive member 5 that penetrates the box body 1, respectively, it is convenient to simultaneously connect the locking member 6 to the box body 1, the conductive member 5 and the terminal 31 of the fuse element 3, so that the fuse element 3 and the box body 1 are fixed at the same time by using one locking member 6, which facilitates installation while saving materials and ensures the installation strength of the fuse element 3.

[0056] In actual operation of this embodiment, a through hole is provided through the top cover 11 of the box body 1, a threaded hole is provided at the penetration end of the conductive member 5, and the locking member 6 is configured as a screw and the end away from the head is fixed by a nut.

[0057] It is not difficult to see that by setting a threaded hole at the insertion end of the conductive member 5, a through hole is set through the top cover 11 of the box body 1, and the locking member 6 set as a screw is inserted into the through hole and the threaded hole in turn, and its head is crimped on the top of the top cover 11 of the box body 1, and the end away from the head is fixed by a nut, so that the insertion end of the conductive member 5 and the terminal 31 of the fuse element 3 are fixedly connected to the box body 1, which makes it more convenient and quick to install and remove the conductive member 5.

[0058] Exemplarily, the locking member 6 can be an M4 screw or a bolt; the nut can be an M4 nut that is matched therewith, and the side of the box body 1 can be provided with an M3 inlaid copper nut to facilitate its installation in the position to be placed. Of course, the specifications of the screws and nuts can also be selected as needed, and this embodiment does not make specific limitations here.

[0059] In another case of this embodiment, reference Figure 5 and Figure 6The conductive member 5 is configured so that the penetration end is parallel to the top cover 11 of the box body 1, and an angle is formed between the remaining portion that penetrates the opening 2 and the penetration end.

[0060] It can be seen that the penetration end of the conductive component 5 is parallel to the top cover 11 of the box body 1, and an angle is formed between the remaining part and the penetration end, so that the penetration end is connected and fixed with the locking component 6 after entering the box body 1, while the remaining part penetrates the box body 1 and is conductively connected to the external device, which is more convenient and reliable to use.

[0061] In actual operation of this embodiment, the angle is configured to be 90 degrees. By setting the above angle to 90 degrees, it is more convenient to connect the conductive component 5 to the outside, and the disassembly and installation process is also more convenient.

[0062] For further reference, Figure 4 The inner wall of the opening 2 near the angle is formed with a rounded corner 8 for fitting therewith.

[0063] It can be seen that by setting the rounded corners 8 on the inner wall of the opening 2, it is easier for the conductive component 5 to pass through or out of the opening 2, and it is also easier for the conductive component 5 and the corners of the opening 2 to fit more closely during use, so as to facilitate the passage of the wire harness.

[0064] In one aspect of this embodiment, the conductive member 5 is configured as a copper busbar, and threaded holes are formed at both ends of each copper busbar.

[0065] It can be seen that by setting the above-mentioned conductive component 5 as a copper busbar, one end is electrically connected to the fuse element 3 through the threaded hole and the locking component 6, and the other end is electrically connected to the external energized device through the threaded hole, while ensuring normal function and strength, and achieving easy installation and disassembly.

[0066] Exemplarily, the conductive member 5 can be constructed into an L shape, and the angle between the two ends of the conductive member 5 can be selected according to the required installation position and posture. In addition to 90 degrees, it can also be an acute angle or an obtuse angle to meet the connection requirements with external live equipment.

[0067] In addition, it should be noted that, in addition to copper busbars, the conductive component 5 may also be made of other conductive metals as needed. Its specific shape and structure can be selected as needed and are not specifically limited in this embodiment.

[0068] In another aspect of this embodiment, the openings 2 are formed through the top cover 11 of the box body 1 and are symmetrically distributed relative to the central axis of the box body 1 .

[0069] It is not difficult to see that by opening the opening 2 through the top cover 11 of the box body 1, it is easier to connect the conductive component 5 with the external device during actual use of the fuse box. The openings 2 are symmetrically distributed relative to the central axis of the box body 1 to facilitate the symmetrical correspondence between the openings 2 and the different terminal ends 31 of the fuse element 3.

[0070] On this basis, reference Figure 7 and Figure 8 The fuse element 3 is formed with two wiring terminals 31 , and the two openings 2 located on both sides of the central axis of the box body 1 correspond to the two wiring terminals 31 of the same fuse element 3 .

[0071] It can be seen that by providing two terminal ends 31 at both ends of the fuse element 3, they are conveniently aligned with the two openings 2 located on both sides of the central axis of the box body 1. While ensuring effective electrical connection between the two terminal ends 31 of the fuse element 3 and the conductive member 5, the orderly installation of the fuse element 3 inside the box body 1 is also achieved, saving the accommodation space inside the box body 1.

[0072] In one case of this embodiment, reference Figure 8 At least one partition 12 is provided inside the box body 1. A receiving groove for receiving the fuse element 3 is formed between the partition 12 and the inner wall of the box body 1. A plurality of receiving grooves are spliced ​​together to form an accommodating space.

[0073] It can be seen that the partition 12 arranged inside the box body 1 facilitates the formation of a receiving groove for accommodating the fuse element 3, so that one fuse element 3 is correspondingly installed inside a receiving groove, and different fuse elements 3 are blocked to prevent short circuit or mutual influence, thereby ensuring the functional reliability of the fuse box.

[0074] In another case of this embodiment, reference Figure 1 and Figure 2 , further comprising: a reinforcing rib 7 arranged on the top of the box body 1 and extending along the length direction and / or width direction of the box body 1 , the reinforcing rib 7 being configured to be connected to each positioning member 4 .

[0075] In this arrangement, the reinforcing ribs 7 are used to increase the strength of the top of the box body 1, and the reinforcing ribs 7 are connected to the positioning member 4 to facilitate the positioning and installation of the auxiliary conductive member 5, thereby enhancing the overall strength and consistency of the fuse box and effectively improving the product yield.

[0076] It should be noted that, during the actual production of the fuse box of the present application, material stealing and reinforcing ribs 7 can be performed on multiple parts of the box body 1 to make the wall thickness of the fuse box more uniform.

[0077] For example, Figure 8As shown, the box body 1 in this embodiment is provided with an opening on a side away from the top cover 11. By providing the opening at the bottom of the box body 1, it is convenient to transfer the fuse element 3 from the bottom to the interior of the box body 1 in actual use, and then pass the copper busbar through the top of the opening 2 and fix its two terminal ends by the locking member. Of course, the above-mentioned opening can also be provided at other positions of the box body 1 as long as it can meet the installation requirements of the fuse element 3. This embodiment does not make any specific restrictions here.

[0078] The present application also proposes an energy storage system, which includes the fuse box as described above.

[0079] It can be seen that by using the above-mentioned fuse box on the energy storage system, the locking component 6 can be used to achieve a detachable connection between the copper busbar and the fuse box, while ensuring the function and strength of the fuse box, effectively avoiding the risk of breakage and mold damage caused by insert injection molding, thereby greatly reducing the processing difficulty of the fuse box, and also reducing the dimensional tolerance and installation accuracy requirements of the copper busbar; the locking component 6 is connected to the box body 1, the copper busbar and the terminal 31 of the fuse element 3, and a single component is used to achieve synchronous fixation and positioning of the three, which is convenient for installation and saves materials, and the detachable installation method also makes it easy for users to disassemble and replace the copper busbar and the fuse element 3, which can meet the user's usage needs.

[0080] The above examples primarily illustrate the fuse box of the present application and the energy storage system including the fuse box. Although only some of the embodiments of the present application have been described, those skilled in the art will appreciate that the present application may be implemented in many other forms without departing from its subject matter and scope. Therefore, the examples and embodiments presented are to be considered illustrative rather than restrictive, and the present application may encompass various modifications and replacements without departing from the spirit and scope of the technical solutions of the present application.
