[0029] Specifically, a current-carrying bar is provided in the terminal housing, so that the current is conducted from the rear side, making the current-carrying interface of the terminal block more uniform and reliable, reducing the current transmission distance, making the current transmission more stable, and not occupying the space on the left and right sides, relatively saving costs. The original shape of the current-carrying bar is "T"-shaped. A first wiring hole is designed on the first bending portion at the current input end of the "T"-shaped current-carrying bar, and multiple wiring holes can be designed on the second bending portion at the output end, enabling the terminal block to achieve one input and multiple outputs. The "T"-shaped current-carrying bar makes the terminal block more stable and cost-saving when in use, and better meets the market demand.

[0032] In this embodiment, a clamping groove 4 is formed between the first bending portion 304 and the second bending portion 305. A fixing portion 5 is clamped in the clamping groove 4. Fixing holes 501 adapted to the first wiring hole 301, the second wiring hole 302, and the third wiring hole 303 are respectively provided at both ends of the fixing portion 5.
[0033] Specifically, the fixing portion is clamped in the clamping groove, so that the first bending portion and the second bending portion are respectively placed at both ends of the fixing portion. Then, fixing holes adapted to the first wiring hole, the second wiring hole, and the third wiring hole are provided on the fixing portion. The fixing portion and the current-carrying bar are fixed by bolts, and at the same time, the nut and the screw can also be used to fix the power cord and the current-carrying bar, so as to complete power conduction.
[0034] In this embodiment, a first fixing groove 6 is provided at the bottom of the fixing portion 5, and the middle part of the current-carrying bar 3 is placed in the first fixing groove 6.
[0035] Specifically, an anti-rotation structure, namely the first fixing groove, is provided on the contact surface between the fixing portion and the current-carrying bar. By placing the current-carrying bar in the first fixing groove, the current-carrying bar can be positioned and fixed to prevent the current-carrying bar from rotating relative to the fixing portion.

[0037] Specifically, the first fixing groove and the second fixing groove are buckled up and down to form a fixing cavity, and the middle part of the current-carrying bar is completely placed in the fixing cavity, further preventing the current-carrying bar from rotating and making its position more stable.
[0038] In this embodiment, engaging grooves 9 are provided on opposite sides of the fixing portion 5, and buckles 10 adapted to the engaging grooves 9 are provided on the inner wall of the through hole 2.
[0039] Specifically, the engaging grooves on the fixing portion cooperate with the buckles on the inner wall of the terminal housing to play a fixing role, so that the fixing portion is fixed in the through hole of the terminal housing.
[0040] In this embodiment, a baffle 11 is provided at the opening of one end of the through hole 2.
[0041] Specifically, a baffle is provided in the middle of the power output terminal port of the through hole, so that the baffle separates the second wiring hole and the third wiring hole, which can prevent the power lines from touching each other and causing a short circuit after the power lines are connected to the second wiring hole and the third wiring hole respectively.
[0042] In this embodiment, grooves 12 are provided at both ends of the terminal housing 1 at the openings of the through holes 2, and the bottom surfaces of the grooves 12 are inclined towards the openings of the through holes 2.
[0043] Specifically, setting the bottom surface of the groove to be inclined can facilitate fixing the power line on the wiring hole.
[0044] In this embodiment, a protective cover 13 is provided on the terminal housing 1 at the ends of the second wiring hole 302 and the third wiring hole 303.
[0045] Specifically, adding a protective cover at the output end of the terminal housing plays a role in preventing touching to avoid electric shock; the upper and lower edges of the protective cover are buckled on the terminal housing, which is convenient for disassembly and assembly.
[0046] In this embodiment, the protective cover 13 is transparent, and being designed to be transparent can facilitate observing the inside of the terminal.
[0047] Assembly method: First, place the nut at the fixing hole on the fixing part, then clip the current guiding strip on the fixing part, and then use the locking combination screw to cooperate with the nut to fix the fixing part and the current guiding strip. Then insert the fixing part with the current guiding strip inserted into the terminal housing from one end of the non-separated through hole until the internal buckle is connected and fixed with the engaging groove, and the assembly of the terminal is completed. When in use, just install the wire nose of the corresponding model at the screw position of the incoming current and tighten it to quickly complete the installation.
