[0044] Please refer to Figure 1-Figure 3, a preferred embodiment of the present invention, comprises a power distribution unit comprising a housing 100 and an output assembly 300. The output assembly 300 comprises a DC busbar assembly 310, a signal board 340, and at least one power outlet module 360. The DC busbar assembly 310 and signal board 340 are mounted within the housing 100, and at least one power outlet module 360 ​​is pluggable and mounted on the DC busbar assembly 310 and signal board 340. The power outlet module 360 ​​utilizes a modular mounting structure that plugs into the DC busbar assembly 310 and signal board 340, allowing for easy hot-swap and replacement. The capacity and quantity of the power outlet modules 360 can be adjusted based on customer needs. Each of the aforementioned components is described in further detail below.

[0045] like Figure 1 As shown, the power distribution unit includes a housing 100, and an input end component 200 and an output end component 300 installed in the housing 100. The input end component 200 and the output end component 300 are arranged along the length direction of the power distribution unit, that is, the input end component 200 is installed at one end of the housing 100, and the output end component 300 is installed at the other end of the housing 100. The housing 100 is provided with hanging ears (not shown in the figure) on the left and right sides, and a plastic hanging nail (not shown in the figure) on the back, which can meet various wall-mounted installation forms. The input end component 200 and the output end component 300 are connected together by copper busbars and cables.

[0046] like Figure 1 As shown, the input-end assembly 200 includes an external power connector 210, an LED display 220, an Ethernet interface 240, and a miniature circuit breaker 250. These external power connector 210, LED display 220, Ethernet interface 240, and miniature circuit breaker 250 are arranged sequentially, from away from the output-end assembly 300 to closer to it. The input power cable is introduced from the external power connector 210 and connected to the miniature circuit breaker 250 to control the overall circuit of the power distribution unit. The LED display 220, Ethernet interface 240, and other components enable functions such as abnormal protection and remote control.

[0047] like Figure 1-Figure 3 As shown, the output terminal assembly 300 includes a DC busbar assembly 310, a signal board 340, and at least one power outlet module 360. The DC busbar assembly 310 and signal board 340 are mounted within the housing 100, and at least one power outlet module 360 ​​is pluggably mounted on the DC busbar assembly 310 and signal board 340. The power outlet modules 360 can be freely configured as needed, and redundant positions can be installed with dummy panels (not shown) to ensure user electrical safety.

[0048] like Figure 2 and Figure 3 As shown, the DC busbar assembly 310 includes a positive busbar 311, a ground busbar 313, and a negative busbar 312. The positive busbar 311, ground busbar 313, and negative busbar 312 are stacked vertically with spacing therebetween. The positive busbar 311 and negative busbar 312 are connected to the miniature circuit breaker 250 via cables. The signal board 340 is mounted inside the DC busbar assembly 310 and connected to the housing 100.

The travel paddle 366 is protruding outside the shell 100. When the travel paddle 366 is pressed, the travel paddle 366 undergoes elastic deformation, which can drive the travel buckle 367 to move into the socket shell 361; when the travel paddle 366 is released, the travel paddle 366 returns to its original state, driving the travel buckle 367 to return to its original position. Figure 2 As shown, the travel buckle 367 can be clamped on the housing 100. Figure 4 As shown, the power socket module 360 ​​further includes a vertical rib 368. The vertical rib 368 is protruding from the outer surface of the socket housing 361 and extends along the plugging and unplugging direction.

[0051] The power socket module 360 ​​is limited by the travel buckle 367 and the vertical rib 368. The travel buckle 367 is controlled by the travel paddle 366 on the front of the power socket module 360. The power socket module 360 ​​can be plugged in and replaced under power on by simply pressing the travel paddle 366 to control the travel buckle 367 and plugging and unplugging along the installation direction.

[0052] The DC busbar assembly 310 is fastened to the housing 100 via a nut assembly 350. Specifically, the nut assembly 350 includes a self-clinching stud 351, a first insulating support post 352, a second insulating support post 353, an insulating ring 354, a screw 355, and an insulating sleeve 356. The positive busbar 311, negative busbar 312, and ground busbar 313 are fastened together via the nut assembly 350. The insulating components of the nut assembly 350 are interlocked, ensuring reliable safety clearances.

[0053] The bottom end of the self-clinching stud 351 is fixedly mounted on the housing 100. The first insulating support column 352 is sleeved onto the self-clinching stud 351. The bottom ends of the negative busbar 312 and the second insulating support column 353 are sleeved onto the top of the first insulating support column 352. Specifically, the top of the first insulating support column 352 is provided with a first boss 3521. The negative busbar 312 is sleeved onto the first boss 3521. The first boss 3521 can limit the left and right position of the negative busbar 312. The outer surface of the first boss 3521 is provided with a first external thread 3522. The bottom end of the second insulating support column 353 is provided with a second internal thread 3532, which mates with the first external thread 3522. The negative busbar 312 is clamped onto the first boss 3521. In conjunction with the second insulating support column 353, the negative busbar 312 is vertically restrained.

[0054] The bottom ends of the ground bar 313 and insulating ring 354 are mounted on the top of the second insulating support column 353, and the bottom end of the screw 355 is inserted into the top of the second insulating support column 353. Specifically, a second boss 3531 is provided at the top of the second insulating support column 353, and the ground bar 313 and insulating ring 354 are mounted on this second boss 3531. The outer surface of the second boss 3531 is provided with a second external threaded portion 3534, which mates with the fourth internal threaded portion 3541 of the insulating ring 354. The ground bar 313 is fixed to the second boss 3531, which acts as a horizontal limiter for the ground bar 313 and, in conjunction with the insulating ring 354, acts as a vertical limiter for the ground bar 313.

[0055] The top of the second boss 3531 is provided with a third internally threaded portion 3533, which mates with the third externally threaded portion 3551 at the bottom of the screw 355. The positive busbar 311 is sleeved over the screw 355, restraining it horizontally. The insulating sleeve 356 covers the top of the screw 355, and the insulating ring 354 cooperates with the insulating sleeve 356 to restrain the positive busbar 311 vertically.

[0056] The power distribution unit is smarter than traditional power distribution units through its internal circuit board 362, power socket module 360 ​​and other combinations. The product can self-manage and handle most abnormal situations, and the management of electrical equipment is more refined, saving manual maintenance and electricity costs.

[0057] The above content is only a preferred embodiment of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scope based on the concept of the present invention.
