[0028] The high-voltage connection assembly 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0029] Reference Figures 1-5 As shown, the high-voltage connection assembly 100 according to an embodiment of the present invention may include: a high-voltage connector 10, a copper busbar 20, and a protective component 30.

[0030] Specifically, the high-voltage connector 10 has a terminal 11, and one end of the copper busbar 20 along its length is connected to the terminal 11, which enables the copper busbar 20 to be connected to the high-voltage connector 10. The high-voltage connector 10 can be connected to other structures through the copper busbar 20 to meet the required connection requirements.

[0031] In addition, such as Figures 2-4 As shown, a protective element 30 is provided above at least the connection area between the terminal 11 and the copper busbar 20. This prevents the connection area between the terminal 11 and the copper busbar 20 from being exposed to the external environment and prevents metal objects (such as bolts) from falling from above the connection area between the terminal 11 and the copper busbar 20, which could cause a short circuit. This avoids dangerous phenomena such as open circuit, fire, and explosion, achieving insulation protection and effectively improving the safety of the high-voltage connection assembly 100. Furthermore, the protective element 30 is a single piece, simplifying its manufacturing, increasing connection strength, and reducing assembly steps, thus improving production efficiency.

[0032] According to an embodiment of the present invention, the high-voltage connection assembly 100 is connected to the terminal 11 of the high-voltage connector 10 via one end of the copper busbar 20 along its length. At least one protective element 30 is provided above the connection area between the terminal 11 and the copper busbar 20, which can prevent the connection area between the terminal 11 and the copper busbar 20 from being exposed to the external environment and prevent metal objects from falling into the connection area between the terminal 11 and the copper busbar 20, thus preventing short circuits. This achieves insulation protection and effectively improves the safety of the high-voltage connection assembly 100. Furthermore, the protective element 30 is an integral piece, which is simple to manufacture, has high connection strength, and reduces assembly steps, thereby improving production efficiency.

[0033] In the embodiments of the present invention, the specific structure of the protective component 30 can be set according to the actual situation, so that the protective component 30 can match different usage requirements, achieve the required insulation protection effect, adapt to different structures and different usage scenarios, and achieve cost reduction and efficiency improvement.

[0034] For example, in some embodiments, such as Figure 2 and Figure 4 As shown, the protective component 30 includes a first shielding plate 31, which is located above the connection area between the terminal 11 and the copper busbar 20. The first shielding plate 31 can completely shield the area above the connection area between the terminal 11 and the copper busbar 20, effectively preventing metal objects from falling from above the connection area between the terminal 11 and the copper busbar 20 and causing a short circuit. This achieves insulation protection and improves the safety of the high-voltage connection assembly 100. Furthermore, the protective component 30 has a simple structure and is easy to manufacture.

[0035] In some embodiments of the present invention, such as Figure 2 As shown, the protective component 30 includes a second shield 32, and the first shield 31 is located along the width direction of the terminal 11 (e.g., Figure 2As shown in the diagram, a second shielding plate 32 is provided at both ends in the left-right direction. The second shielding plate 32 extends in the vertical direction, and the connection area between the terminal 11 and the copper busbar 20 is located between the two second shielding plates 32. The width direction and the vertical direction of the terminal 11 are perpendicular to each other. Thus, the two second shielding plates 32 can shield the connection area between the terminal 11 and the copper busbar 20 on both sides along the width direction of the terminal 11, preventing metal materials from contacting the connection area between the terminal 11 and the copper busbar 20 from the side during collision, which could lead to open circuits and other problems. This achieves the best insulation protection effect and ensures reliable protection.

[0036] According to some embodiments of the present invention, such as Figure 2 and Figure 5 As shown, there are multiple terminals 11 and multiple copper busbars 20. The multiple terminals 11 are spaced apart along the width direction of the terminals 11, and the multiple copper busbars 20 correspond one-to-one with the multiple terminals 11 and are connected. Thus, the high-voltage connector 10 can be connected to multiple other structures through the multiple copper busbars 20 to meet the required connection requirements.

[0037] In addition, such as Figure 2 As shown, the protective component 30 also includes an isolator 33. An isolator 33 is provided between any two adjacent terminals 11. The isolator 33 is connected to the lower end face of the first shielding plate 31, which can fix the isolator 33, which is beneficial to improve the structural strength of the protective component 30. In addition, the isolator 33 can isolate multiple terminals 11, which can increase the creepage distance and ensure safety.

[0038] In embodiments of the present invention, the number of terminals 11 can be flexibly set according to actual conditions. For example, the number of terminals 11 can be as follows: Figure 5 The number shown is two, but it can also be three, four, five, six or more, all of which are within the protection scope of this invention.

[0039] In some embodiments, the plurality of terminals 11 include a positive terminal 11 and a negative terminal 11. The positive terminal 11 and the negative terminal 11 can be blocked by the first shielding plate 31 to prevent the positive terminal 11 and the negative terminal 11 from being disconnected. The positive terminal 11 and the negative terminal 11 can be isolated by the isolator 33 to ensure safety.

[0040] In some embodiments of the present invention, such as Figure 2 As shown, the end face of the second shielding plate 32 facing away from the terminal 11 is provided with a first reinforcing rib 321. The first reinforcing rib 321 can increase the structural strength of the second shielding plate 32 and avoid problems such as deformation of the second shielding plate 32, thereby improving the structural strength of the protective component 30 and ensuring good protection for the connection area of ​​the terminal 11 and the copper busbar 20.

[0041] According to some embodiments of the present invention, such as Figure 2 As shown, the high-voltage connection assembly 100 includes a fixing member 40, through which the high-voltage connector 10 passes to secure it. The protective member 30 also includes a connecting plate 34, which is connected to the first shielding plate 31 and the fixing member 40. Thus, the connecting plate 34 can secure the protective member 30 to the fixing member 40, ensuring reliable fixation and providing good protection for the connection area of ​​the terminal 11 and the copper busbar 20. Furthermore, the connecting plate 34 and the first shielding plate 31 are at an angle to each other, facilitating the connection between the connecting plate 34 and the fixing member 40 and making the connection more convenient, thereby improving assembly efficiency.

[0042] In some embodiments, such as Figure 2 As shown, the connecting plate 34 and the fixing member 40 are connected by a second fastener 50, ensuring a reliable connection between the connecting plate 34 and the fixing member 40, and facilitating disassembly for maintenance or replacement. For example, the second fastener 50 can be a plastic rivet.

[0043] In some embodiments, such as Figure 2 As shown, there can be multiple second fasteners 50. Multiple second fasteners 50 are spaced apart along the length of the connector. Multiple second fasteners 50 can ensure that the connector 34 is reliably fixed on the fixing member 40, avoiding problems such as skewing, thereby ensuring that the protective member 30 has a good protective effect on the connection area of ​​the terminal 11 and the copper busbar 20.

[0044] In embodiments of the present invention, the number of second fasteners 50 can be flexibly set according to actual conditions. For example, the number of second fasteners 50 can be as follows: Figure 2 The number shown is two, but it can also be three, four, five, six or more, all of which are within the protection scope of this invention.

[0045] In some embodiments, such as Figure 1 and Figure 2 As shown, when the high-voltage connection assembly 100 is applied to the battery pack 200, the fixing member 40 is the housing of the battery pack 200, which facilitates the fixing of the high-voltage connector 10 and the protective member 30 inside the battery pack 200, ensuring reliable fixing, and eliminating the need for other connection structures, which helps to reduce production costs.

[0046] In some embodiments of the present invention, such as Figure 2 As shown, a second reinforcing rib 322 is provided between the first shielding plate 31 and the connecting plate 34. The second reinforcing rib 322 can improve the structural strength between the first shielding plate 31 and the connecting plate 34, avoid problems such as breakage between the first shielding plate 31 and the connecting plate 34, and extend the service life of the protective component 30.

[0047] In some embodiments, such as Figure 2 As shown, the included angle between the connecting plate 34 and the first shielding plate 31 is 89°-91°, which ensures the connection strength between the connecting plate 34 and the first shielding plate 31, facilitates the connection between the connecting plate 34 and the fixing member 40, and ensures reliable shielding of the connection area between the terminal 11 and the copper busbar 20 by the first shielding plate 31. Furthermore, the structure is simple and easy to manufacture. For example, in some specific embodiments, the included angle between the connecting plate 34 and the first shielding plate 31 can be 89°, 89.3°, 89.5°, 90°, 90.3°, 90.5°, 91°, etc.

[0048] In some specific embodiments, such as Figure 2 As shown, the high-voltage connection assembly 100 includes a fixing member 40, a high-voltage connector 10 passing through the fixing member 40, multiple terminals 11 spaced apart along the width direction of the terminals 11, and multiple copper busbars 20 corresponding to and connected to the multiple terminals 11. The protective member 30 includes a first shielding plate 31, a second shielding plate 32, and a connecting plate 34. The first shielding plate 31 is located above the connection area between the terminals 11 and the copper busbars 20. The first shielding plate 31 has second shielding plates 32 extending vertically at both ends along the width direction of the terminals 11. The connection area between the terminals 11 and the copper busbars 20 is located between the two second shielding plates 32. The width direction and the vertical direction of the terminals 11 are perpendicular to each other. The first shielding plate 31 and the second shielding plate 32 can protect the connection area between the terminals 11 and the copper busbars 20, preventing short circuits caused by contact between metal objects and the connection area of ​​the terminals 11 and the copper busbars 20. Meanwhile, the connecting plate 34 is connected to the first shielding plate 31 and forms an angle with the first shielding plate 31. The connecting plate 34 is connected to the fixing member 40, which can realize the fixing of the protective member 30.

[0049] An isolator 33 is provided between any two adjacent terminals 11. The isolator 33 is connected to the lower end face of the first shield 31. The isolator 33 can isolate multiple terminals 11, increase the creepage distance, and ensure safety. The end face of the second shield 32 facing away from the terminal 11 is provided with a first reinforcing rib 321, and a second reinforcing rib 322 is provided between the first shield 31 and the connecting plate 34. This can increase the structural strength of the protective component 30 and help extend its service life.

[0050] In addition, the first shielding plate 31, the second shielding plate 32, the isolation component 33, the connecting plate 34, the first reinforcing rib 321 and the second reinforcing rib 322 are integrally injection molded, which makes the structure of the protective component 30 simple, the connection strength high, and reduces the assembly process, thereby improving production efficiency.

[0051] For example, in some embodiments, such as Figure 3 and Figure 4 As shown, the protective component 30 is formed in a ring shape, surrounding the connection area of ​​the terminal 11 and the copper busbar 20. It can protect the connection area of ​​the terminal 11 and the copper busbar 20, effectively preventing metal objects from entering the connection area of ​​the terminal 11 and the copper busbar 20 from above or from both sides of the width direction of the terminal 11, thus preventing short circuits. It achieves insulation protection and improves the safety of the high-voltage connection assembly 100. Moreover, the protective component 30 has a simple structure and is easy to process and manufacture.

[0052] According to some embodiments of the present invention, such as Figure 5 As shown, terminal 11 and copper busbar 20 are connected by first fastener 21 to ensure reliable connection between terminal 11 and copper busbar 20, facilitate installation and disassembly, and make maintenance or replacement convenient.

[0053] In addition, such as Figure 3 and Figure 4 As shown, the inner wall of the protective component 30 is provided with a recess 35. The recess 35 can avoid the first fastener 21, preventing the first fastener 21 from protruding and causing damage to the protective component 30. It also allows the protective component 30 to completely cover the terminal 11, the copper busbar 20, and the first fastener 21, ensuring reliable coverage of the connection area between the terminal 11 and the copper busbar 20, thereby ensuring more reliable insulation protection. For example, the first fastener 21 can be a bolt, and the recess 35 can avoid the head of the bolt.

[0054] In embodiments of the present invention, the specific method of installing the protective component 30 can be set according to actual conditions. For example, the protective component 30 can be first sleeved on the outside of the copper busbar 20 and moved along the length of the copper busbar 20 toward the terminal 11, so that the protective component 30 surrounds the connection area between the terminal 11 and the copper busbar 20.

[0055] In some embodiments, such as Figure 3 and Figure 4As shown, the protective component 30 is a flexible part, giving it elasticity and allowing it to be bent or straightened. The protective component 30 has an opening 36 that extends through it along the extension direction of the terminal 11, which is perpendicular to the vertical direction. Therefore, when installing the protective component 30, it can be directly pried open from the opening 36 and placed over the connection between the connector and the copper busbar 20. The elasticity of the protective component 30 allows it to recover its shape and wrap around the connection between the connector and the copper busbar 20, thus making installation easier and improving assembly efficiency. Similarly, when disassembling the protective component 30, it can be directly pried open from the opening 36 and removed from the connection between the connector and the copper busbar 20, making disassembly easier and improving maintenance efficiency.

[0056] In addition, such as Figure 4 As shown, the opening 36 is located below the terminal 11, which can prevent metal objects from falling from the opening 36 into the connection area between the terminal 11 and the copper busbar 20 and causing a short circuit, ensuring reliable insulation protection and effectively improving the safety of the high-voltage connection assembly 100.

[0057] In some embodiments, the protective component 30 is a polyvinyl chloride (PVC) component. PVC components have simple molds, low costs, and fast production cycles, and are easy and quick to produce, which can improve production efficiency.

[0058] In some embodiments of the present invention, such as Figures 3-5 As shown, there are multiple terminals 11 and multiple copper busbars 20. Each copper busbar 20 corresponds to and is connected to one of the multiple terminals 11. Thus, the high-voltage connector 10 can be connected to multiple other structures through multiple copper busbars 20 to meet the required connection requirements.

[0059] In addition, such as Figure 3 As shown, the protective element 30 is one that surrounds multiple terminals 11, which can meet the protection requirements of multiple terminals 11 by one protective element 30, making the structure of the protective element 30 simple and reducing production costs.

[0060] Or, such as Figure 4 As shown, there can be multiple protective elements 30, which surround multiple terminals 11 respectively. Multiple protective elements can protect multiple terminals 11 respectively, ensuring reliable protection and isolating multiple terminals 11, increasing creepage distance and improving safety.

[0061] The battery pack 200 according to an embodiment of the present invention includes a high-voltage connection assembly 100 according to an embodiment of the present invention. Since the high-voltage connection assembly 100 according to an embodiment of the present invention has the aforementioned beneficial technical effects, the battery pack 200 according to an embodiment of the present invention connects one end of the copper busbar 20 along its length to the terminal 11 of the high-voltage connector 10. At least a protective element 30 is provided above the connection area between the terminal 11 and the copper busbar 20, which can prevent the connection area between the terminal 11 and the copper busbar 20 from being exposed to the external environment, and prevent metal objects from falling into the connection area between the terminal 11 and the copper busbar 20 and causing a short circuit, thus achieving insulation protection and effectively improving the safety of the high-voltage connection assembly 100. Furthermore, the protective element 30 is a single piece, simple to manufacture, has high connection strength, and reduces assembly steps, thereby improving production efficiency.
