[0049] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0050] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, 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, and therefore should not be construed as a limitation of this application.

[0051] In the description of this application, "first feature" and "second feature" may include one or more of the features, "multiple" means two or more, "first feature above" or "below" the second feature may include the first and second features being in direct contact, or the first and second features being in contact through another feature between them, and "first feature above", "above" and "over" the second feature may include the first feature being directly above or diagonally above the second feature, or simply indicate that the first feature is at a higher horizontal level than the second feature.

[0052] The connector assembly 100 according to an embodiment of this application is described below with reference to the accompanying drawings.

[0053] Referring to Figures 1-11, the connector assembly 100 according to an embodiment of this application may include: a housing 10, a high-voltage connection component 20, and a low-voltage connection component 30.

[0054] Specifically, the housing 10 has a first mounting hole 11 and a second mounting hole 12. The high-voltage connection component 20 passes through the second mounting hole 12. The housing 10 can fix the high-voltage connection component 20, which facilitates the connection between the high-voltage connection component 20 and the terminal 200 (e.g., the terminal 200 of the copper-aluminum busbar of the battery pack), thereby fulfilling the high-voltage electrical connection requirements between the high-voltage connection component 20 and the terminal 200.

[0055] Furthermore, as shown in Figures 1-5, 9, and 10, the low-voltage connection assembly 30 includes a first interlocking member 31 and a second interlocking member 32. The first interlocking member 31 passes through the first mounting hole 11, and the second interlocking member 32 is movable in a first position and a second position. When the high-voltage connection assembly 20 is connected to the terminal 200, the second interlocking member 32 can move from the first position to the second position, so that the second interlocking member 32 connects with the first interlocking member 31, thus fulfilling the connection requirement of the low-voltage connection assembly 30 and the fixing requirement of the housing 10 for the low-voltage connection assembly 30. When the high-voltage connection assembly 20 is disconnected from the terminal 200, the high-voltage connection assembly 20 can prevent the second interlocking member 32 from moving towards the second position, thus preventing the first interlocking member 31 and the second interlocking member 32 from connecting.

[0056] Therefore, it is easy to determine whether there is a loose connection between the high-voltage connection component 20 and the terminal 200. Only when the connector assembly 100 is properly connected to the terminal 200 through the high-voltage connection component 20 can the low-voltage connection component 30 be connected. This avoids the risk of arcing or electric shock caused by a loose connection between the high-voltage connection component 20 and the terminal 200 mistakenly connecting the low-voltage connection component 30. This avoids the safety risks of live operation and ensures the safety of the connector assembly 100. At the same time, the connector assembly 100 has a simple structure. The connection detection between the high-voltage connection component 20 and the terminal 200 can be achieved through the low-voltage connection component 30 alone. It also eliminates the need for structures such as the back cover in related technologies, which helps to reduce production costs.

[0057] It should be noted that "high voltage" here refers to a voltage of 60V or higher DC or 30V or higher AC.

[0058] In some embodiments, the housing 10 can be made of nylon. Nylon can withstand greater external forces and pressures, has good structural strength, and can meet insulation requirements to avoid short circuits and other problems, thus ensuring the safety of the connector assembly 100 in use.

[0059] In some embodiments, as shown in Figures 9 and 10, the low-pressure connection assembly 30 further includes a third seal 33, which is located between the first interlock member 31 and the first mounting hole 11. The third seal 33 can seal the gap between the first interlock member 31 and the first mounting hole 11, thereby achieving a seal and preventing external dust or liquids from entering the interior through the gap between the first interlock member 31 and the first mounting hole 11, which could easily cause safety hazards and ensure the safety of the connector assembly 100.

[0060] According to the connector assembly 100 of this application embodiment, a high-voltage connection component 20 is inserted through a second mounting hole 12 of a housing 10, and a first interlocking member 31 is inserted through a first mounting hole 11 of the housing 10. When the high-voltage connection component 20 is connected to the terminal 200, the second interlocking member 32 is adapted to move from a first position to a second position to connect with the first interlocking member 31. When the high-voltage connection component 20 is disconnected from the terminal 200, the high-voltage connection component 20 blocks the second interlocking member 32 from moving to the second position. This facilitates the determination of whether there is a loose connection between the high-voltage connection component 20 and the terminal 200, avoiding the risk of arcing or electric shock caused by a loose connection between the high-voltage connection component 20 and the terminal 200 and mistakenly connecting the low-voltage connection component 30. This avoids the safety risks of live operation. At the same time, the connection detection between the high-voltage connection component 20 and the terminal 200 can be realized only through the low-voltage connection component 30, which is simple in structure and helps to reduce production costs.

[0061] In some embodiments of this application, as shown in Figures 2 and 3, when the second interlocking member 32 is in the second position, the second interlocking member 32 can prevent the high-voltage connection assembly 20 from moving in the direction of disengaging from the second mounting hole 12 (e.g., upward as shown in Figure 2), ensuring that the high-voltage connection assembly 20 is reliably installed in the second mounting hole 12, avoiding problems such as falling off, and preventing personnel from removing the high-voltage connection assembly 20 from the second mounting hole 12 during operation, thus avoiding electric shock and other problems, effectively preventing the risk of personnel operating with electricity and ensuring safety.

[0062] It should be noted that, for ease of description, the directions such as "up", "down", "left", "right", "front" and "back" in this application are based on the orientation relationships shown in the accompanying drawings, and are not limitations on the orientation in actual application.

[0063] According to some embodiments of this application, as shown in Figures 2-5 and Figure 12, the second interlocking member 32 includes a body portion 325 and a limiting portion 326. The body portion 325 extends along the extending direction of the first mounting hole 11 (for example, the front-back direction shown in Figure 4) to facilitate the body portion 325 extending into the first mounting hole 11. The limiting portion 326 is connected to the body portion 325, and the outer peripheral wall of the limiting portion 326 protrudes from the outer peripheral wall of the body portion 325.

[0064] When the high-voltage connection assembly 20 is disconnected from the terminal 200 and the second interlocking member 32 is in the first position, the outer peripheral wall of the limiting part 326 can abut against the outer peripheral wall of the high-voltage connection assembly 20, so that the high-voltage connection assembly 20 prevents the second interlocking member 32 from moving toward the second position, thus preventing the first interlocking member 31 and the second interlocking member 32 from connecting, meeting the required limiting requirements. Moreover, the structure of the second interlocking member 32 is simple, easy to operate, and conducive to reducing production costs. When the second interlocking member 32 is in the second position, the limiting part 326 can abut against the end of the high-voltage connection assembly 20 away from the second mounting hole 12 (for example, the upper end shown in Figure 2), so that the second interlocking member 32 prevents the high-voltage connection assembly 20 from moving toward the direction of disengaging from the second mounting hole 12, preventing the high-voltage connection assembly 20 from coming out of the second mounting hole 12 and causing safety problems, thus meeting the required limiting requirements. Moreover, the structure of the second interlocking member 32 is simple, easy to operate, and conducive to reducing production costs.

[0065] According to some embodiments of this application, as shown in Figures 2-5, 7 and 13, the high-voltage connection assembly 20 includes a connector 21, which passes through the second mounting hole 12, so that the connector 21 can be connected to the terminal 200 opposite to the second mounting hole 12, thereby fulfilling the connection requirement between the high-voltage connection assembly 20 and the terminal 200.

[0066] In addition, as shown in Figures 5 and 13, the high-voltage connection assembly 20 also includes an elastic element 22, which is sleeved on the connector 21 and can push the connector 21 to move in the direction of disengaging from the second mounting hole 12. When the connector 21 is disconnected from the terminal 200, as shown in FIG2, the connector 21 can be pushed up by the driving action of the elastic member 22. When the second interlock member 32 is in the first position, the outer peripheral wall of the limiting part 326 can abut against the outer peripheral wall of the connector 21, thereby the connector 21 can prevent the second interlock member 32 from moving toward the second position. When the connector 21 is connected to the terminal 200, as shown in FIG3, by moving the connector 21 toward the second mounting hole 12 to connect with the terminal 200, the elastic member 22 can be compressed, so that the connector 21 can be offset from the limiting part 326 in the height direction, the second interlock member 32 can move from the first position to the second position, and the limiting part 326 can abut against the end of the connector 21 away from the second mounting hole 12, ensuring that the connector 21 is fixed reliably.

[0067] Therefore, the height difference between the free state and the flattened state of the elastic element 22 can be used to limit the second interlocking element 32, thereby making it easier to determine whether there is a loose connection between the connector 21 and the terminal 200. This avoids the risk of arcing or electric shock caused by a loose connection between the connector 21 and the terminal 200 and accidentally connecting the low-voltage connection component 30. In addition, the elastic element 22 makes it easy to control the position of the connector 21, which simplifies the structure and reduces production costs.

[0068] In some embodiments, the connector 21 can be made of stainless steel, which has good structural strength, avoids deformation, helps to extend service life, and can meet the required electrical conductivity.

[0069] In some embodiments, the elastic element 22 can be a stainless steel element, which has good structural strength, avoids deformation, helps to extend service life, and can meet the required electrical conductivity.

[0070] In the embodiments of this application, the specific structure of the elastic element 22 can be set according to the actual situation. For example, the elastic element 22 can be a spring, etc.

[0071] For example, in some embodiments, the elastic element 22 can be an elastic washer. The elastic washer has a simple structure, is easy to process and manufacture, and can avoid developing other structures and increasing design costs, which helps to reduce costs.

[0072] In some embodiments, as shown in Figures 2, 3, 7, and 13, the connector 21 includes a screw head 212 and a stud 213. One end of the stud 213 along its length is connected to the screw head 212. The stud 213 passes through the second mounting hole 12. The terminal 200 is threadedly connected to the end of the stud 213 along its length away from the screw head 212. An elastic member 22 is sleeved on the stud 213 and located between the terminal 200 and the screw head 212, which can ensure a reliable connection between the connector 21 and the terminal 200. The connector 21 has a simple structure, is easy to process and manufacture, and helps to reduce production costs. Furthermore, the stud 213 can be completely covered by the housing 10, which has a good insulation effect and can prevent risks such as electric arc and electric shock, ensuring the safety of the connector assembly 100.

[0073] In some embodiments of this application, as shown in FIG5, the high-voltage connection assembly 20 further includes a flat washer 23. The flat washer 23 is sleeved on the connector 21 and is located between the terminal 200 and the elastic member 22. When the connector 21 is connected to the terminal 200, the flat washer 23 can ensure that the terminal 200 is subjected to uniform force, ensure that the connection between the connector 21 and the terminal 200 is reliable, and can play an anti-loosening role, ensuring the safety of the connector assembly 100.

[0074] In some embodiments, the flat washer 23 can be made of stainless steel. Stainless steel has good structural strength, avoids deformation, helps to extend service life, and can meet the required conductivity.

[0075] According to some embodiments of this application, as shown in FIG8, a first limiting protrusion 211 is provided on the outer peripheral wall of the connector 21, and a second limiting protrusion 121 is provided on the hole wall of the second mounting hole 12. When the connector 21 passes through the second mounting hole 12 and the connector 21 is disconnected from the terminal 200, the first limiting protrusion 211 and the second limiting protrusion 121 cooperate to prevent the connector 21 from moving in the direction of disengaging from the second mounting hole 12. This enables the pre-installation function of the connector 21, prevents the connector 21 from coming out of the second mounting hole 12, facilitates the subsequent connection of the connector 21 and the terminal 200, and helps to improve assembly efficiency.

[0076] In some embodiments of the connector 21, including a screw head 212 and a stud 213, as shown in FIG7, firstly, the elastic member 22 passes through the stud 213, and the stud 213 passes through the second mounting hole 12. The first limiting protrusion 211 and the second limiting protrusion 121 cooperate to pre-install the connector 21, and the elastic member 22 can drive the screw head 212 to move away from the second mounting hole 12. When the second interlock member 32 is in the first position, the outer peripheral wall of the limiting part 326 can abut against the outer peripheral wall of the screw head 212, thereby the connector 21 can prevent the second interlock member 32 from moving towards the second position; then... The drive connector 21 rotates and moves linearly within the second mounting hole 12, connecting the stud 213 to the terminal 200 and compressing the elastic member 22 to tighten the connector 21. The connector 21 can be offset from the limiting part 326 in the height direction, and the second interlocking member 32 can move from the first position to the second position. The limiting part 326 can abut against the end of the screw head 212 away from the second mounting hole 12, ensuring that the connector 21 is securely fixed. This prevents personnel from removing the connector 21 from the second mounting hole 12 during operation, thus avoiding electric shock and other problems. It effectively prevents the risk of personnel operating with live electricity and ensures safety.

[0077] In some embodiments of this application, the high-voltage connection assembly 20 further includes a first seal. The first seal is sleeved on the end of the connector 21 away from the terminal 200. The first seal is interference-fitted with the wall of the second mounting hole 12, so that the first seal can seal the gap between the second mounting hole 12 and the connector 21, thereby achieving a seal and preventing external dust or liquids from entering the interior through the gap between the connector 21 and the second mounting hole 12, which could easily cause safety hazards and other problems, thus ensuring the safety of the connector assembly 100.

[0078] In some embodiments, the first seal can be a silicone rubber component, which can ensure a reliable seal and provide insulation to prevent short circuits and other problems, thus ensuring safe use.

[0079] According to some embodiments of this application, as shown in Figures 1-7, the first mounting hole 11 extends along a first direction (e.g., the front-back direction shown in Figure 4), and the second mounting hole 12 includes a first mounting sub-hole 122 and a second mounting sub-hole 123. The first mounting sub-hole 122 and the second mounting sub-hole 123 are located on the same side of the first mounting hole 11 in the first direction. The first mounting sub-hole 122 and the second mounting sub-hole 123 are arranged along a second direction (e.g., the left-right direction shown in Figure 3), and the first mounting sub-hole 122 and the second mounting sub-hole 123 extend along a third direction (e.g., the up-down direction shown in Figure 2). The first direction, the second direction, and the third direction are perpendicular to each other. There are two high-voltage connection assemblies 20, and two connectors 21 are respectively inserted through the first mounting sub-hole 122 and the second mounting hole 123, so that the connector assembly 100 can meet the support requirements of the two connectors 21. For example, the two connectors 21 can be formed as positive and negative electrodes respectively to meet the required setup requirements.

[0080] Furthermore, as shown in Figures 1-5, at least one connector 21 is disconnected from the terminal 200 to prevent the second interlocking member 32 from moving toward the second position. That is, one connector 21 is disconnected from the terminal 200, and this connector 21 can prevent the second interlocking member 32 from moving toward the second position; or, both connectors 21 are disconnected from the terminal 200, and both connectors 21 can prevent the second interlocking member 32 from moving toward the second position. This facilitates the determination of whether there is a loose connection between the high-voltage connection component 20 and the terminal 200, so that the connector assembly 100 can be connected to the terminal 200 through at least one connector 21 to realize the connection of the low-voltage connection component 30. This avoids the risk of arcing or electric shock caused by a loose connection between the high-voltage connection component 20 and the terminal 200, thereby avoiding the safety risks of live operation and ensuring the safety of the connector assembly 100.

[0081] In some embodiments of this application, as shown in FIG9, when the second interlocking member 32 is in the first position, a portion of the second interlocking member 32 passes through the first mounting hole 11, which facilitates the second interlocking member 32 to move toward the second position. The first mounting hole 11 can play a good guiding role for the second interlocking member 32, ensuring that the connection between the first interlocking member 31 and the second interlocking member 32 is reliable, which is beneficial to improving assembly efficiency.

[0082] According to some embodiments of this application, as shown in FIG12, the second interlocking member 32 is provided with a protrusion 321, and the wall of the first mounting hole 11 is provided with a groove. When the second interlocking member 32 is in the first position, the protrusion 321 cooperates with the groove to limit the second interlocking member 32, preventing the second interlocking member 32 from coming out of the first mounting hole 11, thereby avoiding problems such as the second interlocking member 32 falling off, ensuring reliable limiting of the second interlocking member 32, facilitating the subsequent operation of the second interlocking member 32 moving toward the second position, and improving assembly efficiency.

[0083] Of course, the first mounting hole 11 has a protrusion 321 on its hole wall, and the second interlocking member 32 has a groove that mates with the protrusion 321, which is also within the scope of protection of this application.

[0084] In some embodiments of this application, as shown in FIG11, the first interlocking member 31 is snapped into the housing 10 to ensure that the first interlocking member 31 is reliably fixed on the housing 10, to prevent the first interlocking member 31 from coming out of the first mounting hole 11, and to facilitate disassembly, maintenance or replacement, etc.

[0085] In some specific embodiments, as shown in Figures 9-11, a buckle 311 is provided on the outer peripheral wall of the first interlocking member 31, and a groove 111 is provided on the hole wall of the first mounting hole 11. By engaging the groove 111 with the buckle 311, the first interlocking member 31 can be reliably fixed in the first mounting hole 11, preventing it from disengaging. This ensures a reliable connection between the first interlocking member 31 and the second interlocking member 32, ensuring the safety of the connector assembly 100. Furthermore, the engagement of the groove 111 with the buckle 311 can provide a reminder of the position of the first interlocking member 31 in the first mounting hole 11, which helps to improve assembly efficiency.

[0086] Of course, the first mounting hole 11 has a buckle 311 on its hole wall, and the outer peripheral wall of the first interlocking member 31 has a groove 111 that cooperates with the buckle 311, which is also within the protection scope of this application.

[0087] According to some embodiments of this application, as shown in Figures 2, 4, 5, and 9-11, the first interlocking member 31 is provided with two wire harnesses 312, and the second interlocking member 32 is provided with a shorting piece 322. When the second interlocking member 32 is in the second position, the shorting piece 322 connects the two wire harnesses 312, realizing the connection requirement of the first interlocking member 31 and the second interlocking member 32, forming a low-voltage circuit path, and realizing the required connection requirement. Moreover, since the shorting piece 322 and the wire harnesses 312 are two independent components, the connection between the first interlocking member 31 and the second interlocking member 32 can be used to determine whether there is a loose connection between the high-voltage connection assembly 20 and the terminal 200, which makes the structure simple and helps to reduce production costs.

[0088] In some embodiments, as shown in Figures 9 and 10, the second interlocking member 32 includes a first housing 327, and a shorting piece 322 is connected to the first housing 327, so that the first housing 327 can support and fix the shorting piece 322, ensuring that the shorting piece 322 is reliably fixed, thereby ensuring that the shorting piece 322 is reliably connected to the wire harness 312 and avoiding problems such as poor contact.

[0089] In some embodiments, as shown in Figures 9 and 10, a mounting groove is provided on one end of the first housing 327 facing the first mounting hole 11 (e.g., the rear end shown in Figure 9). A portion of the shorting piece 322 extends into the mounting groove, and the shorting piece 322 is interference-fitted with the groove wall of the mounting groove, which can prevent the shorting piece 322 from coming out of the mounting groove and ensure that the shorting piece 322 is reliably fixed in the first housing 327.

[0090] In some embodiments, the shorting piece 322 has multiple (two or more) protrusions 321 on the outer peripheral wall of the mounting groove. The multiple protrusions 321 can be interference-fitted with the mounting groove, so that the shorting piece 322 is reliably fixed in the mounting groove. Moreover, the structure of the shorting piece 322 is simple, which can reduce production costs.

[0091] In some embodiments, the shorting piece 322 can be a copper component, which has good conductivity, effectively connects the two wire harnesses 312, ensures reliable connection, and is inexpensive, thus reducing production costs.

[0092] In some embodiments, as shown in Figures 9 and 10, the first interlocking member 31 includes a second housing 313. The second housing 10 is provided with a through hole 314. One end of each wire harness 312 in the length direction passes through the through hole 314, so that the second housing 313 can support and fix one end of the two wire harnesses 312, ensuring that the two wire harnesses 312 are reliably fixed. When the second interlocking member 32 is in the second position, a portion of the shorting piece 322 can pass through the through hole 314, so that the shorting piece 322 can be connected to the two wire harnesses 312, ensuring that the connection between the wire harnesses 312 and the shorting piece 322 is reliable and avoiding problems such as poor contact.

[0093] In some embodiments, as shown in Figures 9 and 10, a fourth sealing element 34 is provided between the wall of the through hole 314 and the outer peripheral wall of the wire harness 312. The fourth sealing element 34 can seal the gap between the through hole 314 and the wire harness 312, thereby achieving a seal and preventing external dust or liquids from entering the interior through the gap between the through hole 314 and the wire harness 312, which could easily cause safety hazards and ensure the safety of the connector assembly 100.

[0094] In some embodiments of this application, as shown in Figures 9 and 10, the second interlocking member 32 is provided with a first hook 323, and the housing 10 is provided with a second hook 13. When the second interlocking member 32 is in the second position, the first hook 323 and the second hook 13 cooperate to ensure that the second interlocking member 32 is reliably limited in the second position, so that the second interlocking member 32 can be stably located in the second position, thereby ensuring that the connection between the second interlocking member 32 and the first interlocking member 31 is reliable, which can improve the safety of the connector assembly 100. Furthermore, the cooperation between the second hook 13 and the first hook 323 can remind the second interlocking member 32 to reach the second position, which is beneficial to improving assembly efficiency.

[0095] According to some embodiments of this application, along the installation direction of the second interlocking member 32 (e.g., the front-to-back direction shown in FIG9), the mating surfaces of the first hook 323 and the second hook 13 extend obliquely toward the side closer to the first mounting hole 11, which can increase the contact area of ​​the first hook 323 and the second hook 13, thereby increasing the reliability of the connection between the first hook 323 and the second hook 13 and ensuring reliable mating between the first hook 323 and the second hook 13.

[0096] In some embodiments of this application, as shown in Figures 9 and 10, the first hook 323 includes an extension 41 and a latching portion 42. The extension 41 is connected to the second interlocking member 32, and the extension 41 extends along the extension direction of the second mounting hole 12 (e.g., the up-down direction shown in Figure 2). The latching portion 42 is disposed on the extension 41, and the latching portion 42 extends toward the mounting direction of the second interlocking member 32. The connection between the latching portion 42 and the extension 41 is spaced apart from both ends of the extension 41 in the length direction. The latching portion 42 is located away from the extension 41. One end of 1 (e.g., the rear end shown in Figure 9) engages with the second hook 13, enabling the engagement of the first hook 323 and the second hook 13. The structure is simple and easy to manufacture. Furthermore, by pressing the end of the extension 41 away from the second interlocking member 32 (e.g., the upper end shown in Figure 9) and rotating it in a direction away from the first mounting hole 11 (e.g., the front shown in Figure 9), one end of the engaging part 42 can be disengaged from the second hook 13, thus disassembling the second interlocking member 32 from the housing 10, making disassembly more convenient.

[0097] According to some embodiments of this application, as shown in Figures 4, 5, 9, and 10, a second sealing element 324 is fitted onto one end of the second interlocking member 32 that extends into the first mounting hole 11. The second sealing element 324 is interference-fitted with the wall of the first mounting hole 11, enabling it to seal the gap between the first mounting hole 11 and the second interlocking member 32. This seal prevents external dust or liquids from entering the interior through the gap between the first mounting hole 11 and the second interlocking member 32, thus avoiding potential safety hazards and ensuring the safety of the connector assembly 100. Simultaneously, when the second interlocking member 32 moves from the first position to the second position, the second sealing element 324 maintains a constant compression, preventing it from dislodging from the first mounting hole 11, avoiding damage to the second sealing element 324, and ensuring a reliable seal.

[0098] In some embodiments, the second seal 324 may be a silicone rubber component, which can ensure reliable sealing and has an insulating effect to avoid problems such as short circuits and ensure safe use.

[0099] In some embodiments, as shown in Figures 4, 5 and 12, the second interlocking member 32 has an assembly groove 328 on one end that extends into the first mounting hole 11. The second sealing member 324 can be located in the assembly groove 328. The assembly groove 328 can limit the second sealing member 324, preventing the second sealing member 324 from sliding on the second interlocking member 32 and ensuring reliable sealing.

[0100] The vehicle according to an embodiment of this application includes a connector assembly 100 according to an embodiment of this application. Since the connector assembly 100 according to an embodiment of this application has the aforementioned beneficial technical effects, the vehicle according to an embodiment of this application, through a high-voltage connection component 20 passing through a second mounting hole 12 in the housing 10, and a first interlocking member 31 passing through a first mounting hole 11 in the housing 10, when the high-voltage connection component 20 is connected to the terminal 200, the second interlocking member 32 is adapted to move from a first position to a second position to connect with the first interlocking member 31; when the high-voltage connection component 20 is disconnected from the terminal 200, the high-voltage connection component 20 blocks the second interlocking member 32 from moving towards the second position. This facilitates the determination of whether there is a loose connection between the high-voltage connection component 20 and the terminal 200, avoiding the risk of arcing or electric shock caused by a loose connection between the high-voltage connection component 20 and the terminal 200 mistakenly connecting the low-voltage connection component 30, thus avoiding the safety risks of live operation. Furthermore, the connection detection between the high-voltage connection component 20 and the terminal 200 can be achieved solely through the low-voltage connection component 30, resulting in a simple structure and reduced production costs.
