[0051] 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 a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0052] According to the first aspect of this application, referring to Figures 1 to 8 This disclosure provides a connector 300. The connector 300 is used to connect a first conductor 260 and a second conductor 250. The connector 300 includes a first housing 310, a first terminal 400, and a second terminal 500. The first housing 310 has a receiving cavity 320. The first terminal 400 and the first conductor 260 are connected within the receiving cavity 320. The second terminal 500 is connected to the second conductor 250, and the second conductor 250 and the first conductor 260 are electrically connected through the first terminal 400 and the second terminal 500.

[0053] Thus, the first housing 310 can block water from the external environment, increasing the difficulty for water to contact the connection between the first terminal 400 and the first conductor 260. This reduces short-circuit accidents caused by moisture intrusion into the containment cavity 320, structurally lowering the possibility of safety accidents caused by circuit failures.

[0054] Furthermore, the connection between the first terminal 400 and the first conductor 260 is physically protected by the first housing 310 within the receiving cavity 320, reducing damage to the connection between the first terminal 400 and the first conductor 260 caused by external mechanical impacts and friction. This also reduces oxidation and corrosion at the connection between the first terminal 400 and the first conductor 260 caused by impurities, maintaining the stability of conductivity and extending the service life of the connector 300 and the overall circuit.

[0055] In some embodiments, the first housing 310 is provided with a first cavity 321, which communicates with the receiving cavity 320, allowing the first terminal 400 to be attached to and detached from the receiving cavity 320 via the first cavity 321. Thus, the first terminal 400 can be maintained via the first cavity 321. However, this design is not limited to this; in some other embodiments, the first housing 310 and the first terminal 400 are integrally formed.

[0056] In some embodiments, the first housing 310 is provided with two first through holes 323 disposed opposite to each other, the first through holes 323 communicating with the receiving cavity 320, and the first conductor 260 passing through the two first through holes 323.

[0057] The two first through holes 323 provide a clear guiding path for the first conductor 260 to pass through, so that it can be accurately put into the receiving cavity 320 without repeatedly adjusting the position of the conductor during assembly, which facilitates the quick connection between the first conductor 260 and the first terminal 400.

[0058] However, this design is not limited to this. In some other embodiments, the first conductor 260 can extend into the receiving cavity 320 through the first cavity 321 to connect with the first terminal 400.

[0059] In some embodiments, the connector 300 includes two first sealing rings 610, which are sleeved on the first conductor 260 and respectively seal the first through hole 323.

[0060] This reduces the pathways for impurities to enter. In one example, the first sealing ring 610 can be connected to the cavity wall of the receiving cavity 320 and the outer peripheral surface of the first conductor 260, thereby forming a seal on the first through hole 323. In another example, the first sealing ring 610 (made of rubber or silicone) can form a tight fit with the inner wall of the first through hole 323 and the outer peripheral surface of the first conductor 260, filling the gap between them through elastic deformation, thus blocking the channel for impurities such as water, moisture, and dust to enter the receiving cavity 320 along the first through hole 323 from the source.

[0061] Furthermore, it improves maintenance convenience and reduces replacement costs. If the first sealing ring 610 ages or breaks due to long-term use, it can be disassembled and replaced separately without replacing the entire first housing 310 or the first conductor 260, thus reducing maintenance costs.

[0062] However, this design is not limited to this. In some other embodiments, the gap between the wall of the first through hole 323 and the first conductor 260 can also be filled with sealant to achieve the sealing of the first through hole 323.

[0063] In some embodiments, in a first direction, the receiving cavity 320 has two opposing first cavity walls, the first cavity walls are provided with a first through hole 323, and the receiving cavity 320 is also provided with two first fixing parts 340, and a first sealing ring 610 is provided between the first fixing part 340 and the adjacent first cavity wall.

[0064] This strengthens the fixation of the first sealing ring 610 and reduces sealing failure caused by displacement. The sealing effect of the first sealing ring 610 depends on the tight fit between the first sealing ring 610 and the first cavity wall and the outer periphery of the first conductor 260. If the first sealing ring 610 is displaced under conditions such as vibration, temperature change, or pulling of the first conductor 260 (e.g., sliding along the first direction), the fitting gap will increase, leading to sealing failure. The two first fixing parts 340 respectively form limiting constraints on adjacent first sealing rings 610. The first fixing part 340 located between the two first sealing rings 610 can prevent the two first sealing rings 610 from approaching each other in the first direction, firmly fixing the first sealing ring 610 in the corresponding sealing position, structurally reducing the decrease in protective performance caused by displacement.

[0065] Furthermore, ensuring uniform sealing pressure improves sealing reliability. The elastic sealing effect of the first sealing ring 610 requires a stable preload (i.e., the degree to which the first sealing ring 610 is compressed). If the first sealing ring 610 is not fixed, slight deviations during assembly or deformation during long-term use may lead to uneven compression (e.g., one side is too loose, and the other side is too tight), affecting the sealing effect.

[0066] Furthermore, the enhanced structural impact resistance facilitates adaptation to complex environments. In environments with high vibration and strong impact (such as vehicle driving), the first conductor 260 may cause the first sealing ring 610 to undergo high-frequency, small-amplitude displacement. Long-term accumulation of this displacement can lead to wear or detachment of the first sealing ring 610 from the fixed structure. The first fixing part 340, by constraining the first sealing ring 610, locks it in a preset position, directly bearing the forces from vibration or impact. This reduces unnecessary wear on the first sealing ring 610, extends its service life, and ensures the long-term stable operation of the connector 300 in complex environments.

[0067] In some embodiments, the first through hole 323 extends in the second direction to the side of the first cavity wall near the first cavity opening 321 to communicate with the first cavity opening 321. The second direction intersects with the first direction. The first fixing part 340 has a first insertion port 341 on the side near the first cavity opening 321. The first conductor 260 can be inserted into the receiving cavity 320 through the first insertion port 341.

[0068] This simplifies the assembly process and makes it suitable for operation in confined spaces. When the conventional first conductor 260 is inserted along the first direction (through-hole axis), it may be difficult to insert due to spatial obstacles in the installation environment (such as obstruction by surrounding components, excessively long paths, etc.). However, insertion along the second direction (first cavity 321 axis) allows for direct insertion and removal using the operating space of the first cavity 321, avoiding the spatial limitations of insertion along the first direction.

[0069] For example, when there are other devices or wires blocking the connector 300 in the first direction, the operator can directly insert the conductor into the through hole and socket in the second direction through the first cavity 321 without adjusting the surrounding parts, which significantly reduces the assembly difficulty.

[0070] Furthermore, after the first conductor 260 is inserted along the second direction, the first insertion port 341 of the first fixing part 340 can form an additional fixing point by cooperating with the first conductor 260, and in conjunction with the limiting of the first through hole 323, the first conductor 260 is constrained.

[0071] In some embodiments, the connector 300 further includes a first seal 620 disposed in the first cavity 321 and together with the first sealing ring 610, seals the first cavity 321.

[0072] The sealing performance of the first cavity 321 directly affects the safety of the connection between the first terminal 400 and the conductor within the receiving cavity 320. After the first sealing element 620 and the first sealing ring 610 work together to seal, they can effectively prevent moisture from entering and reduce the occurrence of short circuits at the connection.

[0073] In some embodiments, the first seal 620 is partially disposed between the two first fixing portions 340 and partially disposed at the two first insertion ports 341.

[0074] The two first fixing parts 340 themselves have a rigid limiting function, clamping the first sealing member 620 between them. The first sealing member 620 can be restricted from moving along the first direction by the constraint of the first fixing parts 340. At the same time, the first sealing member 620 is partially embedded in the two first insertion ports 341, which can restrict the shaking of the first sealing member 620 along the second direction. In this way, it is beneficial to keep the first sealing member 620 in a relatively stable position.

[0075] In one example, the first seal 620 and the first sealing ring 610 can be in physical contact (e.g., the edge of the first seal 620 abuts against the first sealing ring 610). When the first sealing ring 610 has a slight gap due to minor deformation, the first seal 620 can make up for the gap with its own elasticity; conversely, the deformation of the first seal 620 can also be constrained by the first sealing ring 610, and the two support each other.

[0076] In some embodiments, the connector 300 further includes a first cover 371 for covering the first cavity 321.

[0077] The first cavity opening 321 serves as an operating channel for the assembly and disassembly of the first terminal 400. If it remains open for extended periods during non-operational periods, it can become a pathway for water, dust, and impurities to enter the receiving cavity 320. After the first cover 371 closes the first cavity opening 321, it helps to reduce the intrusion of moisture into the receiving cavity 320.

[0078] In some embodiments, the first cover 371 is snapped or plugged into the first housing 310. Furthermore, the first cover 371 is provided with a fourth insertion port 372 for the insertion of the first conductor 260.

[0079] In some embodiments, the first conductor 260 includes a first conductor 262 and an insulating layer 261. In the length direction of the first conductor 260, the first conductor 262 includes a first connecting segment and a second connecting segment. The first connecting segment is disposed outside the receiving cavity 320, and the outer peripheral surface of the first connecting segment is provided with the insulating layer 261. The second connecting segment is disposed inside the receiving cavity 320, and the first terminal 400 is connected to the second connecting segment.

[0080] The first connecting section located outside the containment cavity 320 is directly exposed to the external environment. Its outer insulating layer 261 can effectively isolate the first conductor 262 from other external conductors (such as metal parts or other wires) to avoid short circuits caused by accidental contact; at the same time, it can prevent personnel from accidentally touching live conductors and reduce the risk of electric shock.

[0081] The second connecting section located in the receiving cavity 320 does not require the insulating layer 261 and can be directly and tightly electrically connected to the first terminal 400 (such as crimping, welding, screwing), avoiding the insulating layer 261 from obstructing conductive contact, ensuring smooth current conduction path, reducing contact resistance, and reducing the risk of overheating.

[0082] In some embodiments, the connector 300 further includes a fuse 650, through which the first terminal 400 and the second terminal 500 are connected.

[0083] In this way, overcurrent protection is achieved, preventing safety accidents caused by circuit overload.

[0084] The core function of fuse 650 is to melt its internal fuse element when the current in the circuit exceeds the rated value (such as a short circuit or a current surge caused by equipment failure), automatically cutting off the electrical connection between the first terminal 400 and the second terminal 500, and preventing excessive current from continuously flowing through the first conductor 260 and the second conductor 250. This disconnection mechanism can prevent wires and equipment from burning out due to overcurrent and overheating, and even prevent serious safety accidents such as fires and explosions.

[0085] Furthermore, the circuit protection design is simplified, resulting in higher integration. In traditional designs, the fuse 650 is often installed independently of the connector 300, requiring additional installation space and adding wiring connections. Integrating the fuse 650 into the connector 300 reduces the number of components and connection points in the overall circuit, making the structure more compact.

[0086] In some embodiments, the first terminal 400 includes a first terminal body 410 and two first clamping arms 420, the two first clamping arms 420 being disposed on the same side of the first terminal body 410, the first terminal body 410 being connected to the first conductor 260, and the two first clamping arms 420 clamping the fuse 650.

[0087] This enhances the reliability of the electrical connection between the fuse 650 and the terminal. The two first clamping arms 420 clamp the fuse 650, and through elastic or rigid pressure, make the terminal and the fuse 650 fit tightly together, increasing the contact area while ensuring uniform pressure distribution, effectively reducing contact resistance and reducing heat loss when current passes through.

[0088] In some embodiments, the first terminal 400 further includes two second clamping arms 430 disposed on the first terminal body 410, the two second clamping arms 430 clamping the two first clamping arms 420 to prevent the two first clamping arms 420 from separating.

[0089] When the first clamping arm 420 is used for a long time or is affected by vibration, the clamping force may decrease due to elastic fatigue, which may lead to a gap between it and the fuse 650, resulting in increased contact resistance, increased heating, or even power failure.

[0090] The second clamping arm 430 constrains the first clamping arm 420 from the outside. By continuously applying inward pressure, it counteracts the possible separation tendency of the first clamping arm 420, ensuring that it always maintains a stable clamping force on the fuse 650 and maintains tight electrical contact.

[0091] In some embodiments, the first housing 310 is provided with a second cavity 324 communicating with the receiving cavity 320, and the fuse 650 can be installed and removed from the receiving cavity 320 through the second cavity 324.

[0092] This facilitates the replacement and maintenance of the fuse 650. Furthermore, the first housing 310 also provides protection for the fuse 650.

[0093] In some embodiments, the first housing 310 is provided with a mounting cavity 330, which has a third cavity opening 331 and a fourth cavity opening 332. The second terminal 500 can be installed and removed from the mounting cavity 330 through the third cavity opening 331. The mounting cavity 330 is connected to the receiving cavity 320 through the fourth cavity opening 332. The second terminal 500 is connected to the fuse 650 through the fourth cavity opening 332.

[0094] Thus, the mounting cavity 330 provides a dedicated space for the second terminal 500, and is connected to the receiving cavity 320 (which houses the first terminal 400 and the fuse 650) through the fourth cavity opening 332 without being mixed up. The installation, fixing, and maintenance of the second terminal 500 are concentrated in the mounting cavity 330, while the related operations of the first terminal 400 and the fuse 650 are concentrated in the receiving cavity 320.

[0095] This partitioned design avoids structural interference (such as component size conflicts or tool collisions) between the second terminal 500 and the first terminal 400 and fuse 650 during assembly or maintenance.

[0096] In some embodiments, the connector 300 further includes a second sealing ring 630, which is sleeved on the fuse 650 and is used to seal the fourth cavity 332.

[0097] This reduces the pathways for impurities to enter. In one example, the second sealing ring 630 can be connected to the cavity wall of the receiving cavity 320 and the outer peripheral surface of the fuse 650, thereby forming a seal on the fourth cavity opening 332. In another example, the second sealing ring 630 (made of rubber or silicone) can form a tight fit with the inner wall of the fourth cavity opening 332 and the outer peripheral surface of the fuse 650, filling the gap between them through elastic deformation, thus blocking the channels for water, moisture, dust, and other impurities to enter the receiving cavity 320 along the fourth cavity opening 332 from the source.

[0098] Furthermore, it improves maintenance convenience and reduces replacement costs. If the second sealing ring 630 ages or breaks due to long-term use, it can be disassembled and replaced separately without replacing the entire first housing 310 or the fuse 650, thus reducing maintenance costs.

[0099] However, this design is not limited to this. In some other embodiments, the gap between the fourth cavity 332 and the fuse 650 can also be sealed by filling the gap with sealant.

[0100] In some embodiments, the receiving cavity 320 is further provided with a second fixing part 350. The receiving cavity 320 has a second cavity wall and a fourth cavity opening 332. The second cavity wall and the second fixing part 350 are arranged opposite to each other in a first direction. In the first direction, the second fixing part 350 fixes the second sealing ring 630 to the second cavity wall.

[0101] This strengthens the fixation of the second sealing ring 630 and reduces sealing failure caused by displacement. The sealing effect of the second sealing ring 630 depends on its tight fit with the second cavity wall and the outer periphery of the fuse 650. If the second sealing ring 630 shifts under conditions such as vibration, temperature changes, or tension on the fuse 650 (e.g., sliding along the first direction), the fitting gap will increase, leading to sealing failure. The second fixing part 350 provides a limiting constraint on the second sealing ring 630. The second fixing part 350 can prevent the second sealing ring 630 from moving in the first direction, firmly fixing the second sealing ring 630 in the corresponding sealing position, structurally reducing the decrease in protective performance caused by displacement.

[0102] Furthermore, ensuring uniform sealing pressure improves sealing reliability. The elastic sealing effect of the second sealing ring 630 requires a stable preload (i.e., the degree to which the second sealing ring 630 is compressed). If the second sealing ring 630 is not fixed, slight deviations during assembly or deformation during long-term use may lead to uneven compression (e.g., one side is too loose, and the other side is too tight), affecting the sealing effect.

[0103] Furthermore, the enhanced structural impact resistance facilitates adaptation to complex environments. In environments with high vibration and strong impact (such as vehicle driving), the fuse 650 may cause the second sealing ring 630 to undergo high-frequency, small-amplitude displacement. Long-term accumulation of this displacement can lead to wear or detachment of the second sealing ring 630 from the fixed structure. The second fixing part 350, by constraining the second sealing ring 630, locks it in a preset position, directly bearing the forces from vibration or impact. This reduces unnecessary wear on the second sealing ring 630, extends its service life, and ensures the long-term stable operation of the connector 300 in complex environments.

[0104] In some embodiments, the second fixing part 350 has a second socket 351 on the side near the second cavity 324, and the fuse 650 can be inserted into the receiving cavity 320 through the second socket 351.

[0105] Thus, after the fuse 650 is inserted in the second direction, the second socket 351 of the second fixing part 350 can form an additional fixing point by cooperating with the fuse 650, thereby constraining the fuse 650.

[0106] In some embodiments, a third fixing part 360 is further provided in the receiving cavity 320. The third fixing part 360 is provided with a third socket 361 on the side near the second cavity opening 324. The fuse 650 can be inserted into the third socket 361 along the second direction. The second direction intersects with the first direction. In the first direction, the second fixing part 350 and the third fixing part 360 are arranged opposite to each other.

[0107] The second socket 351 constrains the end of the fuse 650 near the fourth cavity 332, and the third socket 361 constrains the end of the fuse 650 near the second cavity 324. The displacement of the fuse 650 in the first direction is restricted from both ends, thereby reducing the occurrence of poor contact between the fuse 650 and the first terminal 400 and the second terminal 500.

[0108] In some embodiments, the connector 300 further includes a second seal 640 disposed in the second cavity 324, and the second sealing ring 630 and the second seal 640 together seal the second cavity 324.

[0109] The sealing performance of the second cavity 324 directly affects the safety of the connection between the first terminal 400 and the conductor within the receiving cavity 320. After the second seal 640 and the second sealing ring 630 work together to seal, they can effectively prevent moisture from entering and reduce the occurrence of short circuits at the connection.

[0110] In some embodiments, the second seal 640 is partially disposed on the side of the second fixing portion 350 away from the fourth cavity 332, and the second seal 640 is also partially disposed on the second insertion port 351.

[0111] The second fixing part 350 itself has a rigid limiting function, and the second sealing member 640 is partially embedded in the two second sockets 351. The second sockets 351 can limit the shaking of the second sealing member 640 in the second direction.

[0112] In one example, the second seal 640 and the second sealing ring 630 can be in physical contact (e.g., the edge of the second seal 640 abuts against the second sealing ring 630). When the second sealing ring 630 has a slight gap due to minor deformation, the second seal 640 can make up for the gap with its own elasticity; conversely, the deformation of the second seal 640 can also be constrained by the second sealing ring 630, and the two support each other.

[0113] In some embodiments, the connector 300 further includes a second cover 373 for covering the second cavity 324.

[0114] The second cavity 324 serves as an operating channel for the installation and removal of the fuse 650. If it remains open for extended periods when not in operation, it can become a pathway for water, dust, and impurities to enter the receiving cavity 320. When the second cover 373 is closed, it can physically seal the second cavity 324, reducing the intrusion of foreign objects into the receiving cavity 320.

[0115] In some embodiments, the second cover 373 is snap-fitted into the first housing 310.

[0116] In some embodiments, the second terminal 500 includes a second housing 510 and a second terminal body 520 disposed on the second housing 510. The second terminal body 520 is electrically connected to the first terminal 400 and is mounted on the first housing 310 through the second housing 510.

[0117] The second housing 510 serves as the skeleton of the second terminal 500, undertaking the assembly and fixing function with the first housing 310 (e.g., achieving a rigid connection through snaps or bolts). The second housing 510 can also serve as a pre-assembly carrier for the second terminal body 520. The second terminal body 520 is first fixed to the second housing 510, and then the second housing 510 is assembled with the first housing 310 as a whole, avoiding minor deformation when the second terminal body 520 is directly assembled.

[0118] In some embodiments, the connector 300 further includes an anti-detachment housing 530 and an anti-detachment part 540. The second terminal body 520 is disposed on the anti-detachment housing 530. The anti-detachment housing 530 is inserted into the second housing 510. The anti-detachment part 540 extends into the second housing 510 to connect with the anti-detachment housing 530. The anti-detachment part 540 is used to restrict the anti-detachment housing 530 from exiting the second housing 510.

[0119] After the anti-detachment shell 530 is inserted into the second shell 510, the anti-detachment part 540 extends into the shell and connects with the anti-detachment shell 530 (such as snap-fit ​​engagement or boss engaging with groove), forming a rigid lock from the inside, directly restricting the displacement of the anti-detachment shell 530 in the pull-out direction (opposite to the insertion direction).

[0120] This design solves the problem that single insert fits (such as interference fits) are prone to loosening due to vibration and temperature changes: even when in a high-vibration environment for a long time (such as when a car is driving or an industrial equipment is running), or when the material is subjected to thermal expansion and contraction, the anti-detachment part 540 can still prevent the anti-detachment shell 530 from coming out through mechanical locking, ensuring that the second terminal body 520 is always in the working position aligned with the first terminal 400 (or fuse 650), avoiding circuit interruption or poor contact caused by detachment.

[0121] The first terminal 400 can be made of various materials. In some embodiments, the first terminal 400 is made of copper. However, this design is not limited to this; in some other embodiments, the first terminal 400 is made of silver.

[0122] In some embodiments, at least one of the first terminal 400 and the first conductor 260 is provided with a knurled structure at the connection between the first terminal 400 and the first conductor 260.

[0123] Knurling (such as a grid pattern or straight-lined texture) transforms the contact surface between the first terminal 400 and the first conductor 260 from a smooth plane to a micro-interlocking rough surface, resulting in a larger actual contact area compared to a smooth contact. This larger contact area effectively reduces contact resistance and minimizes heat loss during current transmission. In one example, the first terminal 400 and the first conductor 260 are welded, and the welding method can be, but is not limited to, ultrasonic welding. The knurling structure enhances the mechanical anchoring of the weld, increasing its strength.

[0124] The first conductor 260 has many structural forms. In some embodiments, the first conductor 260 is configured as a bus 265. However, this design is not limited to this. In some other embodiments, the first conductor 260 is configured as a wire.

[0125] Bus 265 can be made of various materials. In some embodiments, bus 265 is configured as an aluminum bus. However, this design is not limited to this. In some other embodiments, bus 265 is configured as a copper bus.

[0126] According to a second aspect of this disclosure, a power distribution system 200 is provided, which includes the connector 300 described above. The power distribution system 200 has all the beneficial effects of the connector 300 described above, which will not be repeated here.

[0127] In some embodiments, the power distribution system 200 includes a bus 265, a power supply 210, and electrical devices 220. The power supply 210 is connected to the bus 265. Multiple electrical devices 220 are provided and connected to the bus 265.

[0128] In traditional solutions, each electrical device 220 needs to be connected to the power supply 210 via an independent wire. When there are many electrical devices 220, the total number of wires increases significantly, resulting in a substantial increase in the space occupied by the wires. However, by using a busbar 265, the power supply 210 only needs to be connected to the busbar 265, and multiple electrical devices 220 are then connected to the busbar 265 together. There is no need to lay separate wires for each electrical device 220 to be directly connected to the power supply 210, which greatly reduces the total number of wires and thus effectively reduces the space occupied by the wires.

[0129] Furthermore, the structure of the power distribution system 200 is simplified. Traditional direct multi-wire connections complicate the wiring layout of the power distribution system 200, with numerous intertwined wires that not only hinder installation and maintenance but also increase the risk of line faults. The use of busbar 265 makes the wiring connections of the entire power distribution system 200 more concise and orderly. The connection relationships between the power supply 210 and busbar 265, and between the electrical equipment 220 and busbar 265, are clear and straightforward, simplifying the overall system structure and reducing the difficulty of installation and maintenance.

[0130] In some embodiments, the power distribution system 200 further includes a connector 300, through which at least one electrical device 220 is connected to the busbar 265.

[0131] Adding connector 300 to the power distribution system 200, and having at least one electrical device 220 connected to busbar 265 via connector 300, brings more practical value, with the following specific benefits:

[0132] The connection between busbar 265 and electrical equipment 220 no longer relies on fixed hard connections (such as soldering). Quick plugging and unplugging or assembly can be achieved through connector 300. When electrical equipment 220 needs to be moved, replaced or repaired, there is no need to make complex wiring modifications to busbar 265 or electrical equipment 220 itself. Simply disconnect connector 300 to operate, which greatly simplifies the installation and maintenance process.

[0133] For electrical equipment 220 of different models and interface specifications, different types of connectors 300 can be used to connect to the busbar 265 without adjusting the structure of the busbar 265, thus enhancing the compatibility of the power distribution system 200 with diverse electrical equipment 220.

[0134] In some embodiments, the connector 300 includes a first housing 310, a first terminal 400, and a second terminal 500. The first terminal 400 is disposed on the first housing 310, and the second terminal 500 can be connected to or disconnected from the first housing 310 to control the connection or disconnection between the second terminal 500 and the first terminal 400. One of the first terminal 400 and the second terminal 500 is connected to a busbar 265, and the other is connected to an electrical device 220.

[0135] Without loss of generality, let's take the connection of the first terminal 400 to the busbar 265 as an example. This simplifies the installation and maintenance process. The detachable design allows for step-by-step installation: first, fix the first terminal 400 to the busbar 265, then connect the second terminal 500 to the electrical device 220, and finally install the second terminal 500 onto the first housing 310. This avoids the problem of "difficulty in aligning the other end after fixing one end" in traditional integral connectors 300, making it especially suitable for scenarios with limited space or restricted operation.

[0136] During troubleshooting, the location of the fault can be determined by separating the first housing 310 and the second terminal 500 separately. If the device does not work after docking, the connection between the first terminal 400 and the busbar 265 and the connection between the second terminal 500 and the device can be checked separately to quickly locate whether the problem is with the first terminal 400 and the second terminal 500 themselves or with the docking of the first terminal 400 and the second terminal 500, thus reducing troubleshooting time.

[0137] In some embodiments, the connector 300 further includes a fuse 650, which connects the first terminal 400 and the second terminal 500.

[0138] Thus, circuit overload and short-circuit protection is strengthened. Fuse 650 has a fusing protection feature: when the current of the electrical equipment 220 increases abnormally due to a fault (such as a short circuit or overload), fuse 650 will quickly melt after the current exceeds the rated value, cutting off the current path between the first terminal 400 and the second terminal 500, and preventing excessive current from damaging the busbar 265, the electrical equipment 220, or causing safety accidents such as overheating or fire.

[0139] Compared to traditional system-level protection (such as a main switch), this fuse 650, which is installed in the connection path of a single electrical device 220, can achieve precise local protection: it only cuts off the power supply to the faulty device, without affecting the normal operation of other electrical devices 220 on the busbar 265, thus reducing the scope of the fault's impact.

[0140] Furthermore, the integration and layout of the protection circuit are simplified. By integrating the fuse 650 into the connector 300, there is no need to install a separate external fuse 650 or lay additional protection lines for the electrical equipment 220. This allows for a closer integration of the protection and connection functions of the power distribution system 200, reducing the installation space and wiring complexity of independent protection components.

[0141] In addition, it facilitates troubleshooting and maintenance. When the electrical equipment 220 suddenly loses power, the fuse 650 in the connector 300 can be checked first to see if it has blown. If it has blown, it usually indicates that the electrical equipment 220 has an overload or short circuit problem, providing a clear direction for troubleshooting and reducing the time cost of blind testing.

[0142] Furthermore, it enhances the flexibility of system design. Different electrical devices 220 have different power and safety current requirements, and targeted protection designs can be achieved by equipping connector 300 with fuses 650 with different rated currents, without having to adjust the overall structure of busbar 265 or connector 300.

[0143] When the electrical equipment 220 is upgraded or replaced, only the fuse 650 in the connector 300 needs to be replaced accordingly (to match the current requirements of the new equipment) to continue using the original connector 300 and bus 265, thus reducing the cost of system upgrades.

[0144] In some embodiments, bus 265 includes a plurality of bus segments connected in sequence.

[0145] This improves the ease of installation and transportation of the busbar 265. Integrated busbars 265 are often of fixed length and large size, making them difficult to handle during transport due to space constraints, and potentially causing deformation or damage from collisions. The multi-section design allows the busbar 265 to be disassembled, reducing the length and weight of individual sections, facilitating loading, unloading, and storage during transport, and is particularly suitable for transport scenarios in confined spaces or complex environments.

[0146] During installation, the busbar sections can be pieced together step by step according to the actual layout on site, without the need for major adjustments to the overall busbar 265. This reduces the extra steps such as cutting and grinding caused by size mismatch during installation, thus improving installation efficiency.

[0147] Furthermore, the flexibility and scalability of the power distribution system 200 are enhanced. When the power distribution system 200 needs to expand its power supply range or increase the number of electrical devices 220, the length of the busbar 265 can be directly extended by adding new busbar sections and connecting them to the existing busbar sections, without having to replace the entire busbar 265, thus reducing expansion costs. For example, based on the original three busbar sections 265, adding two new sections can meet the power supply needs of a larger area.

[0148] Furthermore, different busbars can be designed with different specifications (such as different current carrying capacity and different materials) to adapt to the different power load differences in different areas of the power distribution system 200. For example, high-current-carrying busbars are used in areas with concentrated high-power equipment, while conventional busbars are used in areas with low-power equipment, realizing a flexible design of "segment customization".

[0149] Furthermore, it facilitates troubleshooting and maintenance. When bus 265 malfunctions (such as localized poor conductivity or overheating), the fault point can be quickly located through segmented testing. Since multiple bus segments are connected sequentially, the connection between adjacent bus segments can be disconnected one by one to identify which segment is causing the problem, avoiding a complete disassembly of the entire bus 265 and shortening troubleshooting time. If a bus segment needs to be replaced due to aging or damage, only the faulty segment needs to be replaced, without replacing the entire bus 265, reducing maintenance costs and material waste.

[0150] Furthermore, it adapts to complex spatial layout requirements. In practical applications of the power distribution system 200, wiring spaces may contain complex situations such as corners and obstacles. The design of multiple busbars can adjust the connection angles (e.g., by using a rotatable connection structure) to allow the busbar 265 to adapt to non-linear layout paths, improving space utilization. For example, at cabinet corners, a right-angle connection between two busbars can achieve line turning.

[0151] In some embodiments, bus 265 is provided with multiple busbars.

[0152] This improves system safety and reliability. If a single bus 265 fails (such as a short circuit or breakage), it will cause all connected devices to lose power; however, when multiple bus 265s are running independently, a failure of one bus 265 will only affect the devices connected to it, while other bus 265s can supply power normally, reducing the risk of overall system failure and improving the continuity of power supply.

[0153] In some embodiments, the power distribution system 200 further includes a fuse 230, through which the power supply 210 is connected to a plurality of busbars 265.

[0154] In this way, overall protection is achieved on the power supply 210 side to prevent global risks. When the total load of the electrical equipment 220 connected to multiple busbars 265 is too large, or when the busbar 265 itself experiences a serious fault such as a short circuit, the fuse 230 will blow when the current exceeds the rated value, directly cutting off the power supply from the power supply 210 to all busbars 265, thus preventing excessive current from damaging the power supply 210 itself or causing more serious circuit accidents (such as line fires).

[0155] Fuse 230 can control the total current risk from the source and prevent the fault from spreading to the power supply 210 side when the local protection fails, forming a "multi-level protection" safety system.

[0156] Furthermore, the protection logic for total current overload is simplified. Without fuse 230, power supply 210 would have to directly handle the total current surge from multiple busbars 265, which could lead to overload damage to power supply 210 if the total load exceeds the limit. However, the rated current of fuse 230 can be set according to the total power requirements of the system, precisely matching the output capacity of power supply 210. This eliminates the need for a complex overload protection circuit for power supply 210, simplifying the overall protection logic of the system.

[0157] For a system with multiple busbars 265 in parallel, the total current is the sum of the currents of each busbar 265. The fuse 230 can monitor and limit this total current in a unified manner, avoiding system risks caused by a single busbar 265 protection functioning normally but the total current exceeding the limit.

[0158] Furthermore, it facilitates troubleshooting between power supply 210 and bus 265. When all electrical devices 220 connected to bus 265 are unable to receive power, the fuse 230 can be checked first for blown. If it blows, it indicates that the fault may be at the output of power supply 210, the main line, or the total load of bus 265 is over-limit. This provides a clear direction for troubleshooting global power outages and reduces the time cost of checking each bus 265 or device one by one.

[0159] Furthermore, the fuse 230 protects the power supply 210 and extends its service life. The power supply 210 is a core component of the power distribution system 200; its damage could paralyze the entire system, and repair or replacement costs are high. The fuse 230 effectively isolates the power supply 210 from the fault risks of downstream circuits, preventing short circuits, overloads, and other downstream problems from impacting the power supply 210 in reverse, reducing the probability of the power supply 210 burning out due to overcurrent, and thus extending the service life of the power supply 210.

[0160] In some embodiments, bus 265 is configured as an aluminum bus or a copper bus.

[0161] Copper is the second most conductive metal after silver, exhibiting high conductivity and strong current-carrying capacity. Under the same current load, copper busbars can have smaller cross-sectional dimensions, making them suitable for applications requiring high conductivity and where space is limited. Furthermore, copper has good oxidation resistance, and a high-resistivity oxide layer does not easily form on its surface, allowing it to maintain stable conductivity over a long period.

[0162] Copper has high mechanical strength, good ductility, and is easy to process (such as bending, cutting, and drilling), allowing it to adapt to complex installation layouts. At the same time, copper has strong fatigue resistance and is less prone to poor contact due to deformation in vibrating environments.

[0163] Although aluminum has a lower conductivity than copper, aluminum busbars weigh only about one-third of copper busbars for the same current carrying capacity, which helps to reduce the overall weight of the power distribution system.

[0164] Aluminum is abundant, and its raw material cost is far lower than that of copper. For large-scale power distribution systems with a large number of electrical devices (220) and a high demand for busbars (265), choosing aluminum busbars can significantly reduce overall costs while maintaining basic conductivity.

[0165] Aluminum is more ductile than copper, easier to process, and lightweight, making it easy to transport and install.

[0166] There are many types of electrical equipment 220. In some embodiments, electrical equipment 220 is configured as a zone controller or a distribution box. However, this design is not limited to this.

[0167] In some embodiments, the electrical equipment 220 includes a zone control circuit and a power distribution circuit. Thus, the electrical equipment 220 integrates a zone control circuit and a power distribution circuit.

[0168] In some embodiments, the power distribution system 200 further includes a DC-DC converter 240 connected to a bus 265.

[0169] In this way, flexible conversion of DC voltage is achieved to adapt to diverse power needs.

[0170] The DC voltage transmitted by bus 265 may be a fixed value (such as high-voltage DC output from power supply 210), but the rated voltage of different electrical devices 220 often differs. DC-DC converter 240 can convert the voltage on bus 265 to the specific voltage required by electrical device 220, eliminating the need to configure power supply 210 or bus 265 separately for devices with different voltage requirements, greatly improving the system's adaptability to diverse electrical devices 220.

[0171] Furthermore, energy distribution has been optimized, improving system energy efficiency. In power distribution scenarios that include renewable energy sources (such as solar panels) or energy storage devices (such as batteries), the DC voltage output by these devices may be unstable or differ from the standard voltage of bus 265. DC-DC converter 240 can convert unstable voltage into stable voltage before connecting it to bus 265, ensuring voltage stability on bus 265 and preventing voltage fluctuations from affecting the normal operation of other electrical equipment 220.

[0172] Meanwhile, the high-efficiency DC-DC converter 240 can reduce energy loss during voltage conversion (DC conversion is more energy efficient than traditional AC conversion schemes), reduce the overall energy consumption of the system, and is especially suitable for scenarios with high energy efficiency requirements (such as power distribution for new energy vehicles and photovoltaic microgrids).

[0173] Furthermore, it simplifies the system structure and reduces wiring complexity. Without the DC-DC converter 240, multiple busbars 265 of different voltage levels would likely be required to meet the voltage demands of devices, resulting in a complex system structure and redundant wiring. With the DC-DC converter 240, a single busbar 265 can power devices with various voltage requirements, reducing the number of busbars 265, simplifying the wiring layout, and lowering installation and maintenance costs.

[0174] According to a third aspect of this disclosure, a vehicle 100 is provided, which includes the aforementioned power distribution system 200. The vehicle 100 has all the beneficial effects of the aforementioned power distribution system 200, which will not be repeated here.

[0175] In some embodiments, the busbar 265 extends along the front-rear direction of the vehicle 100 and penetrates the cabin area of ​​the vehicle 100.

[0176] This adapts to the distribution characteristics of the electrical equipment 220 in the cabin area, shortening the power supply distance. The electrical equipment 220 in the vehicle 100 cabin area (such as the instrument panel, central control screen, seat heating / ventilation devices, ambient lighting, on-board charger, steering wheel control module, etc.) is typically distributed along the front-to-back direction (from the driver's seat to the rear seats). The busbar 265 runs through the cabin in the front-to-back direction, allowing these devices to be connected to the busbar 265 nearby via short-distance connectors 300 or wires, significantly shortening the power supply line length for a single device.

[0177] Shortening the wiring not only reduces the material cost and space occupied by the conductors, but also reduces resistance loss during current transmission, thus improving the energy efficiency of power distribution in the cabin area.

[0178] Furthermore, it facilitates the expansion of cabin area functions and supports the access of intelligent devices. With the intelligent upgrade of the vehicle 100, the cabin area often requires the addition of new electrical equipment 220 (such as rear entertainment screens, in-vehicle refrigerators, HUD head-up displays, biometric sensors, etc.). The busbar 265, designed to run through the entire cabin, provides a "full-area coverage" connection interface. New devices can be connected to the busbar 265 at any front or rear position via connector 300, without the need to re-lay cross-area main lines.

[0179] For example, when adding a rear seat massage function, the manifold 265 can be connected directly near the seat, without having to run long wires from the front or rear of the vehicle, thus avoiding damage to the integrity of the cabin interior.

[0180] In some embodiments, at least one of the left sill 110 and right sill 120 of the vehicle 100 is equipped with a busbar 265.

[0181] In this way, the space of the left sill 110 and / or right sill 120 is fully utilized to optimize the power distribution layout. The vehicle sill 100 (the longitudinal structure below the left and right doors) is itself a hollow or cavity-like frame, possessing natural accommodation space, and extends along the front-rear direction of the vehicle 100, which highly matches the longitudinal layout requirements of the busbar 265. Installing the busbar 265 here does not require additional valuable space inside the cabin (such as the center console or under the seats), nor does it affect the convenience of passengers getting in and out of the vehicle.

[0182] In some embodiments, the central passage 130 of the vehicle 100 is equipped with a busbar 265.

[0183] The central tunnel 130 (located between the driver's seat and the front passenger seat) is a natural longitudinal passageway within the vehicle's 100-seat cabin, extending from the front to the rear and running through the entire cabin. The busbar 265 is installed here, which can cover all electrical equipment 220 from the front dashboard to the rear passenger area along the central tunnel 130, forming a "central power distribution hub".

[0184] This layout allows electrical equipment 220 in both the front and rear areas (such as the central control screen and gear shift mechanism in the front row, and the air conditioning control panel and charging interface in the rear row) to be connected to the busbar 265 nearby, reducing the use of long cross-area wires, reducing line loss and layout complexity.
