The panel 5 has an operation hole corresponding to the voltage operation rod 33, the voltage operation handle 36 is exposed outside the box, and the first connection split 131 and the second connection split 132 are electrically connected to the first voltage conductor 31 and the second voltage conductor 32, respectively. The first current connector 11 and the second current connector 12 may be current connection wires or current connection guide strips. The voltage connector 13 may be a voltage connection wire or a voltage connection lead.
When the electric meter or the terminal is replaced, the first current connector 11 and the second current connector 12 inside the metering junction box need to be short-circuited first, and then the first connection split 131 and the second connection split 132 need to be broken.

In one embodiment, the first connection sub-body 131 is connected to the first voltage conducting member 31 through a first circuit board (not shown), and the second connection sub-body 132 is connected to the second voltage conducting member 32 through a second circuit board (not shown), wherein the first circuit board and the second circuit board are embedded in the base 4. The connection split bodies are electrically connected with the voltage conductive pieces through the circuit board, so that wiring on the base 4 is facilitated, the circuit board is embedded into the base 4, and the circuit between the connection split bodies and the voltage conductive pieces is prevented from being exposed on the surface of the base 4. In addition, because the circuit board is embedded in the base 4, the metering junction box is prevented from being burnt out due to the fact that other conductive parts on the base 4 are connected with circuits on the circuit board accidentally, and the safety of the metering junction box is improved. In practical design, the first circuit board and the first voltage conducting member 31 and the second circuit board and the second voltage conducting member 32 may be connected by using auxiliary wires.
In order to prevent the first conductive terminal 211 and the second conductive terminal 212 from falling off from the first connection hole 111 and the second connection hole 121, in this embodiment, a first elastic rubber ring 51 is disposed in the first through hole, a first position-limiting hole 55 is disposed in a middle portion of the first elastic rubber ring 51, and a diameter of the first position-limiting hole 55 is smaller than a diameter of the first conductive terminal 211. A second elastic rubber ring 52 is arranged in the second through hole, a second limiting hole 56 is arranged in the middle of the second elastic rubber ring 52, and the aperture of the second limiting hole 56 is smaller than the diameter of the second conductive terminal 212. Wherein, the first elastic rubber ring 51 is adhered to the inner wall of the first through hole, and the second elastic rubber ring 52 is adhered to the inner wall of the second through hole. The first elastic rubber ring 51 and the second elastic rubber ring 52 are mainly used for limiting the first conductive terminal 211 and the second conductive terminal 212. The aperture of the limiting hole is smaller than the diameter of the conductive terminal, and when the conductive terminal passes through the limiting hole, the elastic rubber ring is elastically deformed, so that the conductive terminal is clamped in the limiting hole.
In one embodiment, the current wiring contacts 21 corresponding to the three-phase electrical connection assembly 1 are connected through a first insulating block 22, and the first insulating block 22 is provided with a current operating handle 23. The three current wiring contact pieces 21 are connected into a whole by the first insulating block 22, and all the current wiring contact pieces 21 can be synchronously plugged and unplugged through the current operating handle 23 during specific operation without plugging and unplugging the current wiring contact pieces 21 one by one, so that the operation speed is increased. Of course, in other embodiments, each current wiring contact 21 may be provided separately, and each current wiring contact 21 may be separately inserted and removed during a specific operation.
The current connection contact 21 is connected to the base 4 by an insulated connecting cable (not shown). After the first and second conductive terminals 211 and 212 are pulled out from the first and second connection holes 111 and 121, the current wiring contact 21 is prevented from being separated from the box body due to the presence of the connection cord. In actual design, the length of the connecting rope is usually set according to actual requirements, and the lengths of the first conductive terminal 211 and the second conductive terminal 212 which are inserted and pulled can be all unaffected.
In this embodiment, voltage wire operating member 3 includes a mounting seat 34 mounted on base 4, and first voltage conducting member 31 and second voltage conducting member 32 are respectively mounted on mounting seat 34.

In addition, because the thickness of the mounting seat 34 is equal to the depth of the mounting groove, after the mounting seat 34 is mounted in the mounting groove, the surface of the mounting seat 34 can be flush with the surface of the base 4, and the aesthetic property of the metering junction box is improved.
In one embodiment, the mounting seat 34 is adhered to the mounting groove by an adhesive, so that the mounting seat 34 is connected to the base 4.
In another embodiment, the base 4 is connected with the bottom of the mounting groove through a connecting screw, so that the mounting seat 34 is detachably connected with the base 4, and the metering junction box is convenient to overhaul.
Referring to fig. 3, the second voltage conductor 32 has a first conductor 321 and a second conductor 323, and a gap is formed between the first conductor 321 and the second conductor 323 to form a plug-in slot 322 for the voltage operating rod 33 to plug in. Preferably, the first conductive member 321 and the second conductive member 323 are made of elastic metal, for example, the first conductive member 321 and the second conductive member 323 are both copper sheets, the insertion groove 322 is located at an end of the second voltage conductive member 32 away from the base 4 and has an insertion opening, a width of the insertion groove 322 is gradually reduced from the insertion opening to a position of the base 4, and a width of the insertion groove 322 away from the insertion opening is smaller than a thickness of the voltage operating rod 33, so that after the voltage operating rod 33 is inserted into the insertion groove 322 from the insertion opening, opposite side surfaces of the voltage operating rod 33 are respectively abutted against the first conductive member 321 and the second conductive member 323, and reliability of connection between the voltage operating rod 33 and the first conductive member 321 and the second conductive member 323 is ensured. In this specification, the width of the insertion groove 322 refers to the distance between the first conductive member 321 and the second conductive member 323.
In this embodiment, the voltage connection operating part 3 further includes a second insulating block 35, the three voltage operating rods 33 corresponding to the three-phase electrical connection assembly 1 are connected through the second insulating block 35, and the voltage operating handle 36 is disposed on the second insulating block 35. In the voltage connection operation member 3 having such a structure, the three voltage operation levers 33 are connected as a whole by the second insulating block 35 and share the voltage operation handle 36, so that the voltage operation levers 33 can be operated in synchronization with each other.
Of course, in other embodiments, one voltage operating handle 36 may be correspondingly disposed on each voltage operating rod 33, so that the voltage operating handles 36 can be separately operated.
The panel 5 has a first side surface 57 and a second side surface 58 perpendicular to the first side surface 57, the first side surface 57 is opposite to the electrical connection component 1, the first through hole and the second through hole are both disposed on the first side surface 57, the operation hole has a first hole and a second hole communicated with the first hole, the first hole is disposed on the first side surface 57, and the second hole is disposed on the second side surface 58. When the first and second connection division bodies 131 and 132 need to be electrically connected, the voltage operating lever 33 is pushed by the voltage operating handle 36 from the first hole to the second hole, so that the voltage operating lever 33 is inserted into the insertion groove 322, and the voltage operating lever 33 is in contact with the second voltage conductive member 32, and when the first and second connection division bodies 131 and 132 need to be disconnected, the voltage operating lever 33 is pushed by the voltage operating handle 36 from the second hole to the first hole, and the voltage operating lever 33 is separated from the second voltage conductive member 32.
In a preferred embodiment, an elastic sponge block 53 is disposed in the operation hole, and the elastic sponge block 53 has an operation lever passage 54 at a middle portion thereof through which the voltage operation lever 33 passes, and the width of the operation lever passage 54 is smaller than the thickness of the voltage operation lever 33. Because the elastic sponge block 53 has elastic deformation, when the voltage operating rod 33 is operated, the voltage operating rod 33 can extrude the side wall of the operating rod channel 54, so that the side wall of the operating rod channel 54 is elastically deformed, when the voltage operating rod 33 is not operated, the side wall of the operating rod channel 54 recovers the elastic deformation, the gap of the operating rod channel 54 is reduced, the possibility that dust and other impurities enter the box body from the operating rod channel 54 is reduced as much as possible, and the box body is kept clean and tidy.
Specifically, the elastic sponge block 53 is bonded to the inner side wall of the operation hole by an adhesive.
