[0066] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0067] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0068] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.
[0069] The terms "first," "second," and "third" (if any) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein.
[0070] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such as a process, method, system, product, or maintenance tool that includes a series of steps or units, not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or maintenance tool.
[0071] With the rapid development of new energy vehicles, the amount of battery packs or distribution boxes used in these vehicles is also increasing.
[0072] The distribution box can be installed within the battery pack or in other power-required components of the vehicle. The distribution box includes various high-voltage devices, each connected to a copper busbar. External electrical components are also connected to copper busbars. These two busbars are fastened together, providing electrical connection between the external electrical components and the high-voltage devices in the distribution box. The copper busbars at the connection points between the high-voltage devices and the external electrical components are energized. Insulating caps can be installed on the copper busbars to prevent them from being exposed.
[0073] When maintaining or replacing high-voltage components in a distribution box, tools are needed to loosen the fasteners, disconnecting the copper busbars connected to the high-voltage components from those connected to external electrical components. Alternatively, tools can be used to reconnect the fasteners between the copper busbars connected to the high-voltage components and those connected to external electrical components. In this case, the insulating caps need to be removed. Removing the insulating caps poses a risk of personnel coming into contact with the copper busbars, as the insulating caps are no longer effective in providing insulation protection.
[0074] In related technologies, insulating caps are difficult to provide insulation protection when maintaining or replacing components in a distribution box.
[0075] Based on this, embodiments of this application provide a connection component, a power distribution component, a battery pack, and an electrical device. The connection component can provide insulation and protection when replacing or maintaining components in the power distribution component.
[0076] The battery pack includes battery cells and a power distribution assembly, with the battery cells and the power distribution assembly being electrically connected.
[0077] Figure 1 This is a schematic diagram of the structure of the power distribution component provided in the embodiments of this application; Figure 2 This is an exploded view of the power distribution components provided in the embodiments of this application.
[0078] See Figure 1 and Figure 2 As shown, the power distribution assembly includes a second conductive element 120, a power distribution box 10, and a connecting assembly 100. The power distribution box 10 includes a housing 200. The connecting assembly 100 is connected to the housing 200. One end of the second conductive element 120 is connected to the power distribution box 10, and the other end is provided with a second conductive part 121. The second conductive part 121 is electrically connected to the connecting assembly 100.
[0079] Specifically, the second conductive element 120 further includes a second lead-out portion 122, which is electrically connected to the second conductive portion 121. The second lead-out portion 122 is located within the housing 200. The distribution box 10 also includes components (not shown in the figure), which are located within the housing 200. The second lead-out portion 122 is electrically connected to the components. The battery cell is connected to the connecting assembly 100 and electrically connected to the second conductive portion 121 of the second conductive element 120 via the connecting assembly 100. Thus, the battery cell can be electrically connected to the components in the distribution assembly through the connecting assembly 100 and the second conductive element 120.
[0080] The components can be relays, fuses, or current sensors, etc. The battery cell generates electrical energy. The components rectify or filter the electrical energy generated by the battery cell before outputting it.
[0081] The structure of the connecting component 100 will be described below.
[0082] Figure 3 This is a schematic diagram of the structure of the connection component provided in an embodiment of this application; Figure 4 An exploded view of the connection components provided in the embodiments of this application; Figure 5 This is a schematic diagram of the internal structure of the connection component provided in an embodiment of this application.
[0083] See Figures 3 to 5As shown, the connection assembly 100 provided in this application embodiment includes: a first conductive element 110 and an insulating assembly 130. The first conductive element 110 includes a first conductive portion 111. The insulating assembly 130 has a receiving portion 131 and a clearance portion 139 communicating with the receiving portion 131. The first conductive portion 111 is located in the receiving portion 131 and is used to connect to the distribution box 10 via the clearance portion 139.
[0084] Figure 6 An exploded view of the first conductive element in the connection assembly provided in an embodiment of this application.
[0085] See Figure 4 and Figure 6 As shown, the first conductive element 110 also includes a first lead-out portion 112, which is electrically connected to the first conductive portion 111. The first lead-out portion 112 includes an insulating layer 113 and can extend from the outer casing 200 of the distribution box 10 for electrical connection with the battery cell. Thus, the battery cell, the first lead-out portion 112 of the first conductive element 110, the first conductive portion 111 of the first conductive element 110, the second conductive portion 121 of the second conductive element 120, the second lead-out portion 122 of the second conductive element 120, and the components in the distribution box 10 are sequentially electrically connected. The first lead-out portion 112 is exposed outside the outer casing 200, and an insulating layer 113 can be wrapped around it to provide insulation and protection. The second lead-out portion 122 of the second conductive element 120 is located in the outer casing 200 of the distribution box 10. The outer casing 200 can shield the second lead-out portion 122 to provide insulation protection for the second lead-out portion 122.
[0086] The first conductive part 111 of the first conductive member 110 and the second conductive part 121 of the second conductive member 120 are the connection points between the battery cell and the distribution box 10. When maintenance or replacement of components in the distribution box is required, the electrical connection between the first conductive part 111 and the second conductive part 121 needs to be disconnected, or the first conductive part 111 and the second conductive part 121 need to be reconnected after maintenance is completed.
[0087] During the operation of connecting the first conductive part 111 and the second conductive part 121 or disconnecting the first conductive part 111 and the second conductive part 121, or during the replacement of other components, the connection point of the first conductive part 111 and the second conductive part 121 should be insulated to prevent operators or operating tools from accidentally touching the first conductive part 111 and the second conductive part 121.
[0088] Specifically, the connecting assembly 100 also includes an insulating assembly 130, which has a receiving portion 131. A first conductive portion 111 is disposed in the receiving portion 131, such that the insulating assembly 130 can cover part of the first conductive portion 111. For example, the side of the first conductive portion 111 facing away from the second conductive portion 121 and the periphery of the first conductive portion 111 are exposed. The insulating assembly 130 can cover the side of the first conductive portion 111 facing away from the second conductive portion 121 and the periphery of the first conductive portion 111, thereby providing insulation protection for the side of the first conductive portion 111 facing away from the second conductive portion 121 and the periphery of the first conductive portion 111.
[0089] The insulating component 130 is also provided with a clearance part 139. The first conductive part 111 can be connected to the distribution box 10 via the clearance part 139. Therefore, when connecting or disconnecting the first conductive part 110 from the distribution box 10, it is not necessary to remove the insulating component 130. In other words, when replacing or maintaining the first conductive part 110, the insulating component 130 can also protect the first conductive part 111 of the first conductive part 110.
[0090] In addition, when replacing other components in the power distribution assembly, the insulation assembly 130 can also provide insulation protection for the first conductive part 111 of the first conductive element 110 to prevent operators or operating tools from accidentally touching the first conductive part 111 of the first conductive element 110.
[0091] The connection component 100 provided in this application embodiment includes a first conductive element 110 and an insulating component 130. The first conductive element 110 includes a first conductive portion 111. The insulating component 130 has a receiving portion 131, and the first conductive portion 111 is located in the receiving portion 131, so that the insulating component 130 can wrap a portion of the first conductive portion 111 to provide insulation protection for the first conductive portion 111. The insulating component 130 also includes a clearance portion 139 that communicates with the receiving portion 131. The first conductive portion 111 can be connected to the distribution box 10 via the clearance portion 139. Therefore, the insulating component 130 can also provide insulation protection for the first conductive portion 111 when the first conductive element 110 is connected to or disconnected from the distribution box 10.
[0092] The specific structure of the insulating component 130 will be described below.
[0093] Figure 7 This is a schematic diagram of the structure of the insulating component in the connection assembly provided in the embodiments of this application; Figure 8 This is another structural schematic diagram of the insulating component in the connection assembly provided in the embodiments of this application; Figure 9 This is a schematic diagram of the internal structure of the insulating component in the connection assembly provided in the embodiments of this application.
[0094] See Figure 5 as well as Figures 7 to 9 As shown, the insulating component 130 includes a first surface 130a and a second surface 130b opposite to each other, with a receiving portion 131 between the first surface 130a and the second surface 130b, and a clearance portion 139 including a first through hole 134 and a second through hole 135, with the first through hole 134 located on the first surface 130a side and the second through hole 135 located on the second surface 130b side.
[0095] The insulating component 130 may include a first surface 130a and a second surface 130b opposite to each other along its thickness direction. A receiving portion 131 is located between the first surface 130a and the second surface 130b. That is, the first conductive portion 111 is also located between the first surface 130a and the second surface 130b. A first through hole 134 communicating with the receiving portion 131 is formed on one side of the first surface 130a, and a second through hole 135 communicating with the receiving portion 131 is formed on one side of the second surface 130b. This allows the first conductive portion 111 to be easily connected to the distribution box 10 via either the first through hole 134 or the second through hole 135. The first through hole 134 occupies a portion of the first surface 130a, and the second through hole 135 occupies a portion of the second surface 130b. Therefore, while facilitating the connection of the first conductive portion 111 to the distribution box 10, the insulating component 130 can also cover a significant portion of the outer surface of the first conductive portion 111, providing better insulation protection for the first conductive portion 111.
[0096] The insulating component 130 has an opening 133 that communicates with the receiving portion 131. The first conductive portion 111 can be inserted into the receiving portion 131 through the opening 133, and the first lead-out portion 112 is led out from the opening 133. The shape of the opening 133 can match the contour of the connection between the first conductive portion 111 and the first lead-out portion 112. Thus, the insulating component 130 can wrap around the first conductive portion 111 and provide better protection for the first conductive portion 111.

[0098] join Figures 10 to 12 As shown, the insulating assembly 130 includes a first insulating member 136 and a second insulating member 137. The first insulating member 136 and the second insulating member 137 are detachably connected. A first surface 130a is located on the first insulating member 136, and a second surface 130b is located on the second insulating member 137. The space between the first insulating member 136 and the second insulating member 137 forms a receiving portion 131.
[0099] Please continue reading Figure 10 As shown, when assembling the first conductive element 110 and the insulating assembly 130, the first conductive portion 111 of the first conductive element 110 can be placed on the second insulating element 137 firstly, and then the first insulating element 136 can be placed on the first conductive portion 111 and connected to the second insulating element 137. The detachable connection between the first insulating element 136 and the second insulating element facilitates the assembly of the first conductive element 110 and the insulating assembly 130.
[0100] Please continue reading Figure 11 As shown, the first insulating member 136 includes a first bottom wall 1361 and a first side wall 1362, and a first through hole 134 is located on the first bottom wall 1361; the first side wall 1362 and the first bottom wall 1361 form a partial receiving portion 131.
[0101] Please continue reading Figure 12 As shown, the second insulating member 137 includes a second bottom wall 1371 and a second side wall 1372, a second through hole 135 located on the second bottom wall 1371, and the second side wall 1372 and the second bottom wall 1371 enclose a partial receiving portion 131.
[0102] The portion formed by the first sidewall 1362 and the first bottom wall 1361 is the first receiving portion 1311. The portion formed by the second sidewall 1372 and the second bottom wall 1371 is the second receiving portion 1312. The first insulating member 136 is placed on the second insulating member 137 so that the first receiving portion 1311 and the second receiving portion 1312 together form the receiving portion 131.
[0103] When assembling the first conductive member 110 and the insulating assembly 130, the first conductive portion 111 of the first conductive member 110 can be placed on the second receiving portion 1312 firstly, and then the side of the first insulating member 136 having the first receiving portion 1311 facing the second insulating member 137 and the first insulating member 136 covering the first conductive portion 111, with the first conductive portion 111 located in the receiving portion 131 formed by the first receiving portion 1311 and the second receiving portion 1312. By forming receiving portions 131 on the first insulating member 136 and the second insulating member 137, the space in the receiving portion 131 can be larger, preventing the insulating assembly 130 from squeezing the first conductive portion 111.
[0104] Please continue reading Figure 10 and Figure 12 As shown, the second sidewall 1372 has a first limiting platform 1374, and the first conductive part 111 has a second limiting platform 1112. The first limiting platform 1374 is used to abut against the second limiting platform 1112 to prevent the first conductive part 111 from coming out of the receiving part 131.
[0105] The first limiting platform 1374 is disposed at the opening 133 of the second receiving portion 1312, and the second limiting platform 1112 is disposed at the connection between the first conductive portion 111 and the first lead-out portion 112. The first conductive portion 111 of the first conductive member 110 is placed in the second receiving portion 1312, which is formed by the second side wall 1372 and the second bottom wall 1371. Then, the first insulating member 136 and the second insulating member 137 are connected. When the first lead-out portion 112 of the first conductive member 110 tends to pull the first conductive portion 111 out of the receiving portion 131, the second limiting platform 1112 can abut against the first limiting platform 1374 to prevent the first conductive portion 111 from coming out of the receiving portion 131. In other embodiments, the first limiting platform may also be disposed on the first side wall 1362.
[0106] Please continue reading Figure 10 As shown, in one possible implementation, one of the first insulating member 136 and the second insulating member 137 has a hook 1363 and the other has a groove 1375, and the hook 1363 engages with the groove 1375.
[0107] exist Figure 10 In the illustrated embodiment, a hook 1363 is disposed on the first insulating member 136, and a slot 1375 is disposed on the second insulating member 137. During the process of the first insulating member 136 covering the second insulating member 137, the hook 1363 engages with the slot 1375. Connecting the first insulating member 136 and the second insulating member 137 via the hook 1363 and the slot 1375 simplifies the assembly process of the first insulating member 136 and the second insulating member 137. In other embodiments, the first insulating member 136 and the second insulating member 137 can also be connected by fasteners.
[0108] Please continue reading Figures 3 to 5 As shown, in one possible implementation, the second surface 130b is configured to face the distribution box 10, and the first conductive part 111 is connected to the distribution box 10 via the second through hole 135; the connection assembly 100 also includes an insulating cap 141, which is located on one side of the first surface 130a and covers the first through hole 134.
[0109] The second surface 130b is positioned facing the distribution box 10. The first conductive part 111 is connected to the distribution box 10 via the second through hole 135. Therefore, the side of the first conductive part 111 facing the second surface 130b is shielded by the outer casing 200 of the distribution box 10. The portion of the first conductive part 111 facing the first surface 130a and opposite to the first through hole 134 is exposed. Therefore, an insulating cap 141 can be provided and covered on the first through hole 134. Thus, the insulating cap 141 can shield the first conductive part 111 aligned with the first through hole 134, thereby providing better insulation protection for the first conductive part 111.
[0110] Figure 13 This is a schematic diagram of the structure of the first insulating member and the insulating cap in the connection assembly provided in the embodiments of this application.
[0111] See Figure 13 As shown, in one possible embodiment, the insulating cap 141 includes an operating part 1411 and a limiting part 1412. The limiting part 1412 is located in the receiving part 131. The outer peripheral dimension of the operating part 1411 is smaller than the diameter of the first through hole 134, and the outer peripheral dimension of the limiting part 1412 is larger than the diameter of the first through hole 134.
[0112] The outer periphery of the operating portion 1411 of the insulating cap 141 is smaller than the diameter of the first through hole 134, allowing the insulating cap 141 to be inserted into the first through hole 134 from one side of the first receiving portion 1311, thus simplifying the installation of the insulating cap 141 and the insulating assembly 130. The outer periphery of the limiting portion 1412 of the insulating cap 141 is larger than the diameter of the first through hole 134, preventing the insulating cap 141 from detaching from the first receiving portion 1311.
[0113] The specific connection method between the connection component 100 and the power distribution component will be explained below.
[0114] Figure 14 A schematic diagram of the connection between the connecting component and the second conductive element in the power distribution assembly provided in the embodiments of this application; Figure 15 for Figure 14 An explosion diagram.
[0115] See Figure 14 and Figure 15 As shown, the power distribution assembly also includes a transition assembly 142. The first conductive part 111 has a third through hole 1111, and the second conductive part 121 has a fourth through hole 1211. The transition assembly 142 is inserted into the clearance part 139, the third through hole 1111, and the fourth through hole 1211 to connect the first conductive part 111, the second conductive part 121, and the insulating assembly 130, and to make the first conductive part 111 and the second conductive part 121 electrically connected.
[0116] Specifically, the adapter assembly 142 includes a first end 1421 and a second end 1422. The first conductive part 111 can be first inserted into the receiving part 131; then the first conductive part 111 and the insulating assembly 130 are placed together on the second conductive part 121, and the clearance part 139 (in...) Figure 14 and Figure 15The first through hole 134 and the second through hole 135, the third through hole 1111 and the fourth through hole 1211 are aligned; then the second end 1422 of the adapter assembly 142 is inserted from the first surface 130a side of the insulating assembly 130 into the first through hole 134, the third through hole 1111, the fourth through hole 1211 and the second through hole 135, so that the first conductive part 111, the second conductive part 121 and the insulating assembly 130 are connected, and the adapter assembly 142 makes the first conductive part 111 and the second conductive part 121 electrically connected.
[0117] The adapter assembly 142 is disengaged from the first through hole 134, the third through hole 1111, the fourth through hole 1211, and the second through hole 135. Thus, as the adapter assembly 142 is removed, the first conductive part 111 and the second conductive part 121 are also electrically disconnected. This arrangement simplifies the connection method between the connection assembly 100 and the power distribution assembly.
[0118] Figure 16 This is a schematic diagram of the structure of the transfer component in the power distribution assembly provided in the embodiments of this application; Figure 17 for Figure 16 An explosion diagram.
[0119] See Figure 15 and Figure 16 As shown, the adapter assembly 142 includes a first adapter 1423 and a second adapter 1424. The first adapter 1423 and the second adapter 1424 are detachably connected, and the second adapter 1424 is connected to the housing 200. An insulating cap 141 is wrapped around the end of the first adapter 1423 that is away from the second adapter 1424.
[0120] For example, the first adapter 1423 can be a nut, and the second adapter 1424 can be a stud.
[0121] Figure 18 This is a schematic diagram showing the connection between the second adapter and the housing in the power distribution assembly provided in the embodiments of this application.
[0122] See Figure 18As shown, when connecting the connecting assembly 100 to the housing 200, the second adapter 1424 can be first placed in the housing 200 to connect with it. For example, the end of the second adapter 1424 away from the first adapter 1423 can be pre-embedded in the housing 200. The fourth through hole 1211 of the second conductive part 121 is placed in the housing 200, so that the second adapter 1424 is inserted into the fourth through hole 1211. The semi-finished product formed by the first conductive part 110 and the insulating assembly 130 is placed on the housing 200, so that the second adapter 1424 is inserted into the second through hole 135, the third through hole 1111, and the first through hole 134. An operator or operating tool applies force to the first adapter 1423 to connect the first adapter 1423 and the second adapter 1424. The detachable connection between the first adapter 1423 and the second adapter 1424 allows the second adapter 1424 to be pre-connected to the housing 200, making the connection between the connecting assembly 100 and the housing 200 more reliable.
[0123] The insulating cap 141 is wrapped around the end of the first adapter 1423 that is away from the second adapter 1424. When the operator or operating tool applies force, it comes into contact with the insulating cap 141. Therefore, the operator or operating tool can be prevented from contacting the adapter assembly 142.
[0124] In other embodiments, the first adapter 1423 may be a stud, and the second adapter 1424 may be a nut, with the nut pre-connected to the housing 200.
[0125] Please continue reading Figure 12 and Figure 15 As shown, in one possible embodiment, the insulating component 130 has a recess 132 that communicates with the receiving portion 131, and at least a portion of the second conductive portion 121 is located in the recess 132.
[0126] The second surface 130b has a recess 132 on one side. The second conductive part 121 of the second conductive member 120 can be a horseshoe-shaped conductive post connected to the second lead-out part 122. The second conductive part 121 extends into the recess 132. Thus, the periphery of the recess 132 can provide insulation protection for the side of the second conductive part 121.
[0127] The recess 132 can be formed on the second bottom wall 1371. That is, the recess 132 and the second through hole 135 are both located on the second bottom wall 1371. Thus, the opening for connecting the connecting assembly 100 to the housing 200 of the power distribution assembly and the opening for electrically connecting to the second conductive member 120 of the power distribution assembly are located on the same side, so that the connecting assembly 100 is connected to the power distribution assembly and electrically connected to the power distribution assembly at the same time.
[0128] It should be noted that the second surface 130b also has a stepped portion 138, and the notch 1212 of the horseshoe-shaped second conductive portion 121 can be engaged with the stepped portion 138 to prevent the second conductive member 120 from rotating.
[0129] The specific structure of the outer casing 200 of the distribution box 10 will be described below.
[0130] Please continue reading Figure 1 and Figure 2 As shown, the housing 200 includes a first housing 210 and a second housing 220, the first housing 210 and the second housing 220 being detachably connected; the first housing 210 or the second housing 220 has a first wall 211 and a second wall 221, the first wall 211 and the second wall 221 being located on opposite sides of the connecting assembly 100.
[0131] The first housing 210 and the second housing 220 can be detachably connected via fasteners. Figure 1 and Figure 2 In the embodiment shown, the first housing 210 has a plurality of pull rings 212, and the second housing 220 has a boss 222. The pull rings 212 are engaged with the boss 222 to connect the first housing 210 and the second housing 220.
[0132] The first housing 210 has a first wall 211 extending from the outer surface of the first housing 210, and the first housing 210 also has a partial second wall 221 extending from the outer surface of the first housing 210. The second housing 220 has a partial second wall 221 extending from the outer surface of the second housing 220. When the first housing 210 and the second housing 220 are assembled together, the partial second wall 221 on the first housing 210 and the partial second wall 221 on the second housing 220 are aligned. The first wall 211 and the second wall 221 are located on opposite sides of the connecting assembly 100, so that the first wall 211 and the second wall 221 can provide insulation protection for the connecting assembly 100.
[0133] The second adapter 1424 and the second conductive element 120 are both connected to the first housing 210 or the second housing 220. Figure 1 , Figure 2 and Figure 18 In the embodiment shown, both the second adapter 1424 and the second conductive element 120 are connected to the second housing 220.
[0134] In one possible implementation, the first adapter 1423 has a first mounting hole 1425, and the second adapter 1424 is inserted into the first mounting hole 1425.
[0135] Specifically, the second adapter 1424 can be a stud, the end of which can be pre-embedded in the second housing 220 during its formation. The threaded portion of the stud extends out of the second housing 220, and the stud is inserted into the fourth through hole 1211 of the second conductive part 121. The first adapter 1423 can be a nut, and its inner wall has internal threads.
[0136] The semi-finished product formed by the first adapter 1423, insulating cap 141, first conductive element 110 and insulating assembly 130 is placed on the second housing 220, so that the stud is aligned with the first mounting hole 1425 in the first adapter 1423 through the first through hole 134, the second through hole 135 and the third through hole 1111. The operating tool applies force on the insulating cap 141, so that the first adapter 1423 and the second adapter 1424 are threadedly connected.
[0137] In another possible implementation, the second adapter 1424 has a second mounting hole (not shown in the figure), and the first adapter 1423 is inserted into the second mounting hole.
[0138] The second adapter 1424 can be a nut, with internal threads on the inner wall of the second mounting hole. The first adapter 1423 can be a stud, with external threads on the stud. The semi-finished product formed by the first conductive element 110 and the insulating assembly 130 is placed in the second housing 220, such that the stud is aligned with the second mounting hole in the second adapter 1424 via the first through hole 134, the second through hole 135, the third through hole 1111, and the fourth through hole 1211. The operating tool applies force to the insulating cap 141, causing the first adapter 1423 to be threadedly connected to the second adapter 1424.
[0139] The first insulating element 136 is connected to the first outer shell 210, and the second insulating element 137 is connected to the second outer shell 220.
[0140] When the first adapter 1423 is a stud and the second adapter 1424 is a nut, the first insulating member 136 can be connected to the first housing 210 firstly, for example, the first insulating member 136 and the first housing 210 are integrally formed, and the second insulating member 137 can be connected to the second housing 220, for example, the second insulating member 137 and the second housing 220 are integrally formed. Thus, while connecting the first housing 210 and the second housing 220, the first insulating member 136 and the second insulating member 137 can form the receiving portion 131, which simplifies the assembly process of the connecting assembly 100. Then, the first conductive part 111 is inserted into the receiving part 131, and the first adapter 1423 is aligned with the second mounting hole in the second adapter 1424 via the first through hole 134, the second through hole 135, the third through hole 1111 and the fourth through hole 1211. The operating tool applies force to the insulating cap 141, so that the first adapter 1423 and the second adapter 1424 are threadedly connected.
[0141] This application also provides an electrical device, including the battery pack or the distribution box 10 described above.
[0142] Electrical equipment can be vehicles, aircraft, ferries, computers, or energy storage cabinets that use battery packs for power. Vehicles can be electric vehicles (EVs), pure electric vehicles (PEVs / BEVs), hybrid electric vehicles (HEVs), range-extended electric vehicles (REEVs), plug-in hybrid electric vehicles (PHEVs), or new energy vehicles.
[0143] The battery pack is used to power electrical equipment, which may include one or more battery packs. The electrical equipment may also include a distribution box 10, which can connect the battery pack of the electrical equipment to other electrical devices.
