[0016] Figure 3 This is a second exploded view of the wiring terminals for connecting the neutral and live wires of this utility model. Detailed Implementation

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0018] like Figures 1 to 3 As shown, the terminal block for connecting the neutral and live wires includes a mounting bracket and a terminal block 3 that cooperate with each other; the terminal block 3 includes multiple connection ports 31 on the back, which can be connected to the live wire and the neutral wire respectively, and the connection ports 31 are fixed by screws; the bottom surface of the terminal block 3 has inwardly protruding clips 32 on both sides; the terminal block 3 is equipped with a fuse.

[0019] The mounting bracket includes two fixing brackets, a first fixing bracket 1 and a second fixing bracket 2, which are fixed on both sides of the terminal block 3. The structures of the first fixing bracket 1 and the second fixing bracket 2 are mirror symmetrical.

[0020] The back of the first fixing frame 1 is provided with a first slot 11 and a second slot 12. The first slot 11 and the second slot 12 are respectively opposite to the top edge and the bottom edge of the switch box support frame. A ramp is provided above the first slot 11 and the second slot 12. The first fixing frame 1 can be fixed by pushing the first slot 11 and the second slot 12 into the upper and lower sides of the switch box support frame using the ramp.

[0021] The front end of the first fixing frame 1 is provided with first connecting members 13 arranged from top to bottom. The first connecting members 13 include a first groove 131 that cooperates with the terminal block 3. In this embodiment, four first connecting members 13 can be provided. The two first connecting members 13 at the upper end are arranged vertically, and the two first connecting members 13 at the lower end are arranged horizontally. This structure can reduce the volume of the first fixing frame 1, so that more terminal blocks 3 can be connected. The bottom end of the inner side of the first groove 131 is provided with a first buckle 132 that cooperates with the bottom end locking block 32 of the terminal block 3. The top end of the first buckle 132 is provided with a protrusion that protrudes along the axial direction of the first groove 131 and faces the inner side of the first groove 131. The distance from the inner wall of the first groove 131 to the inner side of the protrusion is the same as the distance from the outer wall of the terminal block 3 to the inner side of the locking block, ensuring that the terminal block 3 is stably connected in the first groove 131. The outer side of the protrusion is a slope, and the terminal block 3 can slide into the first groove 131 by means of the slope during assembly.

[0022] During assembly, the terminal block 3 is first fixed on the first connector 13 of the first fixing bracket 1. After fixing, the second fixing bracket 2 is fixed on the other end of the terminal block 3 relative to the first fixing member 1. The first fixing member 1 and the second fixing member 2 can be fixed inside the switch box by using the slot on the back to cooperate with the support frame of the switch box. The wiring port 31 on the terminal block 3 can be used to pass wires. The fuse inside the terminal block 3 can protect the circuit, which is safe, convenient and reduces construction costs.

[0023] The wiring terminal for connecting the neutral and live wires of this utility model is fixed to both ends of the wiring terminal 3 by a first fixing frame 1 and a second fixing frame 2 arranged opposite to each other. The inner sides of the first fixing frame 1 and the second fixing frame 2 are provided with buckles that cooperate with the locking block 32 at the bottom of the wiring terminal 3. Two locking grooves that cooperate with the upper and lower ends of the switch box support frame are provided at the bottom of the first fixing frame 1 and the second fixing frame 2, which facilitates installation and disassembly. After installation, the wiring port 31 on the wiring terminal 3 can act as a transfer station, which is safe, convenient and reduces construction costs.
