The switch body 1 is a split type and includes a base, a top cover and a middle cover. Three mounting slots 101 are arranged side by side in the switch body 1, and each mounting slot 101 corresponds to a wiring slot 102. Switching mechanisms 2 are respectively arranged on the three mounting slots 101, and each switching mechanism 2 includes a metal back plate 201. Among them, a unidirectional current transformer 3 for monitoring current is provided in each mounting slot 101. The metal back plate 201 passes through the corresponding unidirectional current transformer 3 and is electrically connected to the wire in the wiring slot 102 through the outgoing plate 4.

[0018] The switch body 1 is equipped with a display screen 6 and a measurement module 7. The unidirectional current transformer 3 is electrically connected to the display screen 6 and the measurement module 7.

[0019] A receiving groove 103 is provided on one side of the switch body 1, and the measuring module 7 is installed inside the receiving groove 103.

[0020] Example 2 Based on Embodiment 1, this embodiment provides a detailed description of the fixing method between the metal back plate 201 and the cable outlet plate 4. The metal back plate 201 has a first mounting hole 2011 at its end, and the cable outlet plate 4 has a second mounting hole 401 on its side wall. When the metal back plate 201 and the cable outlet plate 4 are installed in the mounting groove 101, the second mounting hole 401 coincides with the first mounting hole 2011, and bolt holes are provided at corresponding positions in the mounting groove 101. During assembly, the first mounting hole 2011, the second mounting hole 401, and the bolt holes are aligned, and then the bolts are rotated to screw the threaded end of the bolts into the bolt holes, thereby fixing the metal back plate 201 and the cable outlet plate 4. This fixing method is simple in structure, convenient to operate, and ensures a firm connection between the metal back plate 201 and the cable outlet plate 4, guaranteeing the stability of the circuit connection.

[0021] Example 3 Based on the above embodiments, this embodiment further optimizes the connection structure between the outgoing plate 4 and the wiring slot 102. Two forked pieces 402 are symmetrically arranged at one end of the outgoing plate 4 near the wiring slot 102. The two forked pieces 402 penetrate the side wall of the mounting slot 101 and extend into the interior of the wiring slot 102. Each wiring slot 102 has a partition 1021 inside, with the two forked pieces 402 located on opposite sides of the partition 1021. This design avoids mutual interference between conductors of different phases, improving the safety and stability of the circuit.

[0022] Each wiring trough 102 has a wire outlet cover 5 inside. Two wiring holes 501 are symmetrically opened on the wire outlet cover 5. A pressure plate 502 is slidably connected to each wiring hole 501 by a bolt. The forked plate 402 extends into the corresponding wiring hole 501 and is located below the pressure plate 502. The position of the pressure plate 502 can be controlled by adjusting the bolt, thereby achieving reliable crimping of the wire and ensuring the stability of the electrical connection.

[0023] Both sides of the wiring trough 102 are provided with protruding ribs 1022, and both sides of the cable outlet cover 5 are provided with slots 503. When the cable outlet cover 5 is installed in the wiring trough 102, the protruding ribs 1022 are inserted into the slots 503. This plug-in installation method facilitates the quick installation and removal of the cable outlet cover 5, and also enhances the connection between the cable outlet cover 5 and the wiring trough 102.
