[0032] like Figures 1 to 4 As shown, in this embodiment, a junction box includes:

[0033] The housing 100 has a receiving cavity, and is provided with a first output inlet 110 and a second output inlet 120 communicating with the receiving cavity, wherein the first output inlet 110 and the second output inlet 120 face different directions;

[0034] An input component 200 is disposed in the accommodating cavity and is used to receive power input;

[0035] The output assembly 300 is removably mounted within the housing. One end of the output assembly 300 is electrically connected to the input assembly 200, while the other end can selectively face the first output inlet 110 or the second output inlet 120. The output assembly 300 can be electrically connected to a load via the first output inlet 110 or the second output inlet 120. This design allows the user to quickly adjust the direction of the current output path by simply removing and installing the output assembly 300, eliminating the need for complex disassembly and rewiring of the entire device. This significantly reduces maintenance complexity and costs while also improving maintenance efficiency.

[0036] Specifically, if Figures 1 to 4 As shown, in this embodiment, the shell 100 is rectangular and includes a detachably connected base 101 and a shell cover 102, and the two cooperate to form a rectangular accommodating cavity for accommodating the input component 200 and the output component 300, and forming protection for the input component 200 and the output component 300 so that electrical energy can be stably managed and distributed.

[0037] In this embodiment, the base 101 and the shell cover 102 are respectively recessed from the inside to the outside, and the two are detachably connected by screws 500, ensuring the convenience of disassembly, assembly and maintenance of the input component 200 and the output component 300.

[0038] To connect the output assembly 300 to an external load, in this embodiment, the housing 100 is provided with a first output inlet 110 and a second output inlet 120 that communicate with at least the accommodating cavity. This allows the output assembly 300 to be electrically connected to the load via the first output inlet 110 or the second output inlet 120. This design not only provides a connection path between the output assembly 300 and the load but also allows for a variety of connection paths, significantly increasing the flexibility of the combiner box's installation and use.

[0039] In this embodiment, the first output inlet 110 and the second output inlet 120 can be oriented oppositely or perpendicularly to each other, depending on the needs. Preferably, they are arranged oppositely. This design effectively optimizes space utilization within the housing 100 while reducing interference between current output paths. Furthermore, the relative arrangement allows users to flexibly select the connection direction based on the load location, further enhancing the system's adaptability and ease of operation.

[0040] In this embodiment, both the first output inlet 110 and the second output inlet 120 are equipped with at least one circular positive electrode access hole 111 and a circular negative electrode access hole 112 to meet the basic power supply requirements of the load and ensure normal input and output of current. Preferably, the first output inlet 110 and the second output inlet 120 are each equipped with two positive electrode access holes 111 and two negative electrode access holes 112, arranged in a straight line. This design not only provides users with redundant connection options, but also allows for the simultaneous connection of multiple loads or meets the needs of multiple input channels for a single load.

[0041] Preferably, in this embodiment, the first output inlet 110 and the second output inlet 120 are arranged on the left and right sides of the shell 100, and the positive electrode access hole 111 and the negative electrode access hole 112 are both formed by the semicircular structures respectively arranged on the base 101 and the shell cover 102.

[0042] In this embodiment, the housing 100 is further provided with a converging inlet 130 located between the first output inlet 110 and the second output inlet 120 and communicating with the accommodating cavity. The converging inlet 130 includes a plurality of circular through-holes 131. This design allows the user to flexibly connect more power sources or circuits according to actual needs, and can transmit current from different power sources or circuits to the input component 200, where it is then integrated and uniformly transmitted to the output component 300.

[0043] Preferably, in this embodiment, the confluence inlet 130 is provided at the bottom of the housing 100 , and the through hole 131 thereof is formed by the combination of semicircular structures provided at the bottom of the base 101 and the bottom of the housing cover 102 .

[0044] Preferably, in this embodiment, each positive electrode access hole 111, negative electrode access hole 112, and through hole 131 is provided with a sealing piece that can be knocked off by external force. When the user needs to use the corresponding positive electrode access hole 111, negative electrode access hole 112, or through hole 131, simply knock off the corresponding sealing piece. This design prevents dust from entering the junction box through unused positive electrode access holes 111, negative electrode access holes 112, and through holes 131.

[0045] To enable quick positioning of the output component 300 after removal, in this embodiment, a first fixing structure 140 and a second fixing structure 150 are provided within the accommodating cavity. The output component 300 can be selectively detachably connected to the first fixing structure 140 or the second fixing structure 150. When the output component 300 is connected to the first fixing structure 140, one end of the output component 300 is opposite the first output access port 110. When the output component 300 is connected to the second fixing structure 150, one end of the output component 300 is opposite the second output access port 120. This design provides a clear installation position for the output component 300. When removing and reinstalling the output component 300, the user can quickly complete positioning without repeatedly adjusting the position, significantly reducing the number of steps required when switching current paths and improving work efficiency. Furthermore, the user can simply remove and reconnect the output component 300 to the desired fixing structure to complete the current path switching without having to disassemble and assemble the entire junction box, significantly reducing the number of steps and time costs.

[0046] In this embodiment, the first fixing structure 140 and the second fixing structure 150 have the same structure, wherein the first fixing structure 140 is located on the side close to the first output inlet 110, and the second fixing structure 150 is located on the side close to the second output inlet 120. Both include a first fixing base 141, which is provided with a first threaded hole 141a extending along its length, and the output component 300 can be removably fixed to the first threaded hole 141a via a screw 500. Because the first fixing structure 140 and the second fixing structure 150 are designed identically, the user does not need to re-adapt to a different fixing method when installing or replacing the output component 300, simplifying the operation process. The design of fixing the output component 300 to the first threaded hole 141a via a screw 500 provides a secure and reliable connection method, avoiding loosening problems caused by vibration or other external forces.

[0047] Preferably, in this embodiment, the first fixing seat 141 is cylindrical, vertically arranged on the base 101, and integrally formed with the base 101, and one end of the first fixing seat 141 extends away from the base 101 and has a first threaded hole 141a so that the first connecting member 310 of the output component 300 can be firmly fixed on the first fixing seat 141.

[0048] Preferably, in this embodiment, two groups of first fixing seats 141 are provided, and a plurality of reinforcing ribs are arranged along the circumference of the outer wall of the first fixing seat 141. This design further improves the reliability of the installation of the output assembly 300.

[0049] In this embodiment, the first fixing structure 140 and the second fixing structure 150 further include a second fixing base 142, which is provided with a first mounting groove 142a. The output assembly 300 is removably secured to the first mounting groove 142a via a fastener 600, with the end of the fastener 600 snapping into the first mounting groove 142a. This design provides a mounting point for the overload protector 330 of the output assembly 300, ensuring a secure fixation and facilitating assembly and disassembly of the overload protector 330. Furthermore, compared to conventional designs in which a nut 620 is embedded in the second fixing base 142, this design significantly reduces production costs.

[0050] Preferably, in this embodiment, the second fixing seat 142 is cylindrical, vertically arranged on the base 101, and integrally formed with the base 101, and one end of the second fixing seat 142 extends away from the base 101 and has a first mounting groove 142a so that the first connecting member 310 of the output component 300 and the overload protector 330 can be firmly fixed on the second fixing seat 142.

[0051] Preferably, in this embodiment, the first mounting groove 142a is in the shape of a hexagonal nut 620, whose size and shape are compatible with the head of the bolt 610 of the fastener 600. During assembly, the head of the bolt 610 is first inserted into the first mounting groove 142a. The first connector 310 is then passed through the bolt 610 to abut against the first and second fixing seats 141 and 142. One end of the overload protector 330 is then passed through the bolt 610 to abut against the first connector 310. Finally, the nut 620 is screwed onto the bolt 610 and tightened. It is worth noting that because the first connector 310 is fixed to the first fixing seat 141 via the screw 500, the overload protector 330 can be fixed within the accommodating cavity via the second fixing seat 142.

[0052] Preferably, in this embodiment, the first fixing seat 141 and the second fixing seat 142 have the same height, and there is a gap therebetween for the end portion of the overload protector 330 to be installed.

[0053] In this embodiment, a third fixing base 160 is provided between the first fixing structure 140 and the second fixing structure 150. One end of the output assembly 300 is detachably connected to the third fixing base 160, and the other end is selectively detachably connected to the first fixing structure 140 or the second fixing structure 150. The distance between the third fixing base 160 and the first fixing structure 140 is equal to the distance between the third fixing base 160 and the second fixing structure 150. This design not only provides support and fixing points for the other end of the overload protector 330 and the second connector 320, but also allows the second connector 320 to be conveniently electrically connected to the overload protector 330 and the input assembly 200, significantly improving maintenance convenience and space utilization. Furthermore, the equidistant design of the third fixing base 160 from the first fixing structure 140 and the second fixing structure 150 ensures symmetry and consistency when the output assembly 300 switches between different positions, avoiding connection instability caused by distance differences.

[0054] In this embodiment, the third fixing base 160 is provided with a second mounting slot 161. The output assembly 300 is removably secured to the second mounting slot 161 via a fastener 600, with the end of the fastener 600 snapping into the second mounting slot 161. This design provides a mounting point for the second connecting member 320, ensuring not only a secure fixation but also eases assembly and disassembly of the second connecting member 320. Furthermore, compared to conventional designs in which a nut 620 is embedded in the third fixing base 160, this design significantly reduces production costs.

[0055] Preferably, in this embodiment, the third fixing base 160 is cylindrical, vertically arranged on the base 101, and integrally formed with the base 101, and one end of the third fixing base 160 extends away from the base 101 and has a second mounting groove 161 so that the second connecting member 320 of the output component 300 and the overload protector 330 can be firmly fixed on the third fixing base 160.

[0056] Preferably, in this embodiment, the second mounting groove 161 is in the shape of a hexagonal nut 620, whose size and shape are compatible with the head of the bolt 610 of the fastener 600. During assembly, the head of the bolt 610 is first inserted into the second mounting groove 161. The second connecting member 320 is then passed through the bolt 610 and abutted against the third fixing seat 160. The other end of the overload protector 330 is then passed through the bolt 610 and abutted against the second connecting member 320. Finally, the nut 620 is screwed onto the bolt 610 and tightened. It is worth noting that because the overload protector 330 is already fixed, the second connecting member 320 can be fixed within the accommodating cavity via the third fixing seat 160.

[0057] Preferably, in this embodiment, the third fixing seat 160 is at the same height as the first fixing seat 141 and the second fixing seat 142 , thereby ensuring the flatness of the installation of the overload protector 330 .

[0058] In this embodiment, the accommodating cavity is further provided with a third fixing structure 170 and a fourth fixing structure 180 having a height difference and aligned with the confluence inlet 130. The third fixing structure 170 and the fourth fixing structure 180 are arranged in an upper and lower structure, and two groups of the first fixing structure 140, the second fixing structure 150, and the third fixing seat 160 are each provided in an upper and lower structure, corresponding one-to-one with the third fixing structure 170 and the fourth fixing structure 180 to form independent positive and negative paths. This design provides a clear installation position for the input component 200. When the user removes and reinstalls the input component 200, the position can be quickly completed without repeated adjustments, thereby significantly reducing the number of operation steps and improving work efficiency. In addition, the height difference design between the third fixing structure 170 and the fourth fixing structure 180 avoids interference when wiring the positive and negative poles.

[0059] In this embodiment, the third fixing structure 170 and the fourth fixing structure 180 are the same, and both include a fourth fixing seat 171 and a fifth fixing seat 172, wherein the fourth fixing seat 171 is provided with a second threaded hole 171a extending along its own length direction, and the positive electrode bus structure 210 and the negative electrode bus structure 220 can be detachably fixed on the second threaded hole 171a by a screw 500, ensuring the stability of the installation of the positive electrode bus structure 210 and the negative electrode bus structure 220; the fifth fixing seat 172 is provided with a third mounting groove 172a, and the positive electrode bus structure 210 and the negative electrode bus structure 220 can be detachably fixed on the third mounting groove 172a by a fastener 600, and the end of the fastener 600 can be stuck in the third mounting groove 172a. This design provides an installation point for the second terminal 410 of the positive bus structure 210 and the negative bus structure 220, which not only ensures that the second terminal 410 can be firmly fixed, but also improves the convenience of disassembly and assembly of the second terminal 410; and, compared with the traditional design of embedding the nut 620 on the fifth fixing seat 172, it effectively saves production costs.

[0060] In this embodiment, the fourth fixing seat 171 is cylindrical, vertically arranged on the base 101, and integrally formed with the base 101. One end of the fourth fixing seat 171 extends away from the base 101 and has a second threaded hole 171a so that the bus bars of the positive bus structure 210 and the negative bus structure 220 can be firmly fixed on the fourth fixing seat 171.

[0061] Preferably, in this embodiment, two groups of fourth fixing bases 171 are provided, arranged in a left-right structure, and a plurality of reinforcing ribs are arranged along the circumference of the outer wall of the fourth fixing base 171. This achieves the fixation of both ends of the busbar and further improves the stability of the busbar fixation.

[0062] In this embodiment, the fifth fixing seat 172 is cylindrical, vertically arranged on the base 101, and integrally formed with the base 101. One end of the fifth fixing seat 172 extends away from the base 101 and has a third mounting groove 172a so that the second terminal 410 of the input component 200 can be firmly fixed on the fifth fixing seat 172.

[0063] Preferably, in this embodiment, a plurality of fifth fixing seats 172 are provided and arranged in a straight line to allow multiple current connections. The third mounting groove 172a is in the shape of a hexagonal nut 620, and its size and shape are adapted to the head of the bolt 610 of the fastener 600. During assembly, the head of the bolt 610 is first inserted into the third mounting groove 172a, and then the busbar is passed through the bolt 610 to abut against the fourth fixing seat 171 and the fifth fixing seat 172. Then, one end of the second connecting member 320 is passed through the bolt 610 to abut against the busbar, and finally the nut 620 is screwed onto the bolt 610 and tightened. It is worth noting that since the busbar is fixed to the fourth fixing seat 171 by the screw 500, the second terminal 410 can be fixed in the accommodating cavity through the fifth fixing seat 172.

[0064] Preferably, in this embodiment, the fourth fixing seat 171 and the fifth fixing seat 172 have the same height.

[0065] In this embodiment, the input assembly 200 is located within the housing chamber and is used to receive power input and consolidate multiple currents, allowing them to efficiently and flexibly power the load through the output assembly 300. This design effectively integrates current from different sources, ensuring a stable and reliable power supply.

[0066] In this embodiment, the input assembly 200 includes a positive current bus structure 210 and a negative current bus structure 220, which are removably fixed to the upper and lower ends of the inner wall of the base 101.
