[0031] This embodiment provides an electric energy meter component, such as Figures 1 to 3 As shown, it includes an electric energy meter 1 and an auxiliary replacement part 2. The electric energy meter 1 includes an electric energy meter body 11 and a plurality of terminal blocks 12 arranged on the electric energy meter body 11, each terminal block 12 is provided with a spring sheet 121, and the spring sheet 121 is made of conductive material; there are multiple auxiliary replacement parts 2, and the multiple auxiliary replacement parts 2 correspond to the multiple terminal blocks 12 one by one. The auxiliary replacement part 2 includes a connecting rod 21, an insulating part 22 arranged at one end of the connecting rod 21, and a sleeve 23 located at the other end of the connecting rod 21, the connecting rod 21 is made of conductive material, and the insulating part 22 and the sleeve 23 are both made of insulating material; the wire 100 can be plugged into the connecting rod 21, the connecting rod 21 can be inserted into the terminal block 12 and slidably cooperate with the terminal block 12, the outer wall of the connecting rod 21 can contact the spring sheet 121, so that the wire 100 and the spring sheet 121 are electrically connected, and the connecting rod 21 can partially extend into the sleeve 23, so that the insulating part 22 contacts the spring sheet 121, so that the auxiliary replacement part 2 is not charged. In this embodiment, the electric energy meter 1 is illustrated by a three-phase electric energy meter, which has three phases A, B, and C and two neutral wire terminals, and is provided with eight terminals 12 in total. Therefore, eight auxiliary replacement parts 2 are also provided.

[0032] The electric energy meter assembly provided in this embodiment is operated without power when the electric energy meter 1 is newly installed. First, the wire 100 is plugged into the connecting rod 21, and then the connecting rod 21 is inserted into the terminal 12 of the electric energy meter 1, and the spring piece 121 of the terminal 12 is allowed to contact the outer wall of the connecting rod 21. The current can be transmitted to the electric energy meter 1 through the wire 100, the connecting rod 21 and the spring piece 121, thereby realizing the electrical connection between the wire 100 and the terminal 12 of the electric energy meter 1. The multiple terminals 12 of the electric energy meter 1 are connected to the auxiliary replacement part 2 in sequence through the above steps to complete the installation of the new electric energy meter 1. When the electric energy meter 1 fails and needs to be replaced, the connecting rod 21 drives the wire 100 to be partially set in the sleeve 23. At this time, the insulating part 22 contacts the spring sheet 121. The insulating part 22 and the sleeve 23 are both made of insulating materials, so that the auxiliary replacement part 2 is not charged as a whole. The auxiliary replacement part 2 and the wire 100 are taken out from the terminal 12 of the electric energy meter 1, and the multiple auxiliary replacement parts 2 and the multiple terminal 12 of the electric energy meter 1 are separated one by one in sequence, and then the new electric energy meter 1 is replaced. The electric energy meter assembly provided in this embodiment does not cause phase-to-phase short circuits or ground short circuits between phase lines and neutral lines when installing a new electric energy meter 1 or replacing the electric energy meter 1, thereby reducing the risk of electric shock for maintenance personnel when replacing the meter. Moreover, the multiple auxiliary replacement parts 2 correspond to the multiple terminal 12 of the electric energy meter 1 one by one, and it is not easy to cause phase sequence disorder during the replacement of the electric energy meter 1, thereby improving the efficiency of wiring.

[0033] It can be understood that the terminal 12 of the electric energy meter 1 provided in this embodiment is a hollow structure, which ensures that the auxiliary replacement part 2 can be taken out from the terminal 12 of the electric energy meter 1. Preferably, a fixing piece can be provided at the terminal 12 of the electric energy meter 1, and when the outer wall of the connecting rod 21 contacts the spring sheet 121, the fixing piece fixes the connecting rod 21 to restrict its movement, for example, the fixing piece can be a clamp, thereby clamping the connecting rod 21 to restrict its movement.

[0034] Specifically, Figure 1 As shown, the electric energy meter 1 further includes a power indicator light 13 and a display screen 14 arranged on the electric energy meter body 11. The power indicator light 13 is used to display whether the electric energy meter body 11 is powered on, and the display screen 14 is used to display the power consumption.

[0035] Specifically, Figure 2As shown, a plug-in groove 211 is provided on the outer wall of the connecting rod 21, and the wire 100 can be partially arranged in the plug-in groove 211, and the charged end of the wire 100 abuts against the groove wall of the plug-in groove 211. The connecting rod 21 is made of conductive material, and the charged end of the wire 100 abuts against the groove wall of the plug-in groove 211 to ensure the transmission of current. More specifically, the plug-in groove 211 is a stepped groove, and the plug-in groove 211 is set as a stepped groove to adapt to wires 100 of different sizes and models. In this embodiment, the connecting rod 21 is made of a metal material alloy steel to ensure the structural strength of the connecting rod 21.

[0036] Specifically, Figure 2 As shown, the plug-in groove 211 is an annular structure, the connecting rod 21 is a cylindrical structure, and the axis of the plug-in groove 21 is set at an angle with the axis of the connecting rod 21, so that the wire 100 can be set at an angle with the connecting rod 21. In this embodiment, the wire 100 is set at 90° perpendicular to the connecting rod 21.

[0037] Specifically, a clamping member (not shown) is provided on the inner wall of the plug-in groove 211 , and the clamping member is used to clamp the wire 100 to prevent the wire 100 from shaking in the plug-in groove 211 and prevent the wire 100 from being plugged in unstably.

[0038] Specifically, Figure 2 As shown, an external thread is provided on the outer wall of the connecting rod 21, and an internal thread is provided on the sleeve 23. The internal thread and the external thread cooperate with each other. The connecting rod 21 is rotated so that the connecting rod 21 can be inserted into the sleeve 23. While the connecting rod 21 is rotated, the wire 100 can be wound around the connecting rod 21, and part of it is located between two adjacent threads of the external thread. The connecting rod 21 and the wire 100 are partially screwed into the sleeve 23, so that the charged end of the wire 100 is located in the sleeve 23. The sleeve 23 is made of insulating material, which is convenient for the subsequent replacement of the electric energy meter 1.

[0039] Specifically, Figure 2 As shown, the insulating member 22 is a hollow conical structure, and the insulating member 22 has a large end and a small end, and the small end faces the sleeve 23 and is connected to the connecting rod 21. When the connecting rod 21 is rotated, because its small end faces the sleeve 23, the outer wall of the insulating member 22 plays a certain guiding role. When the spring sheet 121 abuts against the insulating member 22, the charged end of the wire 100 is located in the sleeve 23, so that the auxiliary replacement part 2 is not charged.

[0040] Specifically, Figure 2 and Figure 3As shown, the auxiliary replacement part 2 also includes a knob 24, which is arranged at one end of the connecting rod 21 and partially extends out of the large end of the insulating part 22. The knob 24 is used for manual holding. The operation and maintenance personnel manually rotate the knob 24 so that the knob 24 can rotate and drive the connecting rod 21 to rotate, so that the connecting rod 21 partially extends into or extends out of the sleeve 23. The knob 24 is provided to facilitate the operation and maintenance personnel to rotate the connecting rod 21. It can be understood that the knob 24 is made of insulating material to prevent the operation and maintenance personnel from electric shock. In other embodiments, the knob 24 is provided at one end of the connecting rod 21 and is provided in the insulating part 22. The operation and maintenance personnel can extend their hands into the insulating part 22 to rotate the knob 24, or the knob 24 may not be provided, and one end of the connecting rod 21 can be directly extended out of the large end of the insulating part 22. The operation and maintenance personnel hold one end of the connecting rod 21 and rotate the connecting rod 21.

[0041] Furthermore, if Figure 2 and Figure 3 As shown, the electric energy meter 1 includes a limiter, which is used to limit the rotation of the knob 24. An annular groove 2112 is provided at the connection between the connecting rod 21 and the knob 24. The limiter includes a button portion 15, a transmission portion 16 and a limiter 17. The button portion 15 is provided on the electric meter body 11 and is slidably matched with the electric meter body 11. The transmission portion 16 is used to transmit and connect the button portion 15 and the limiter 17. The limiter 17 of the limiter is located in the insulating member 22. When the button portion 15 is pressed, the transmission portion 16 transmits power to the limiter 17, so that the limiter 17 moves to the left (as shown in FIG. 1 ). Figure 3 As shown in the left side, the limiting portion 17 is located at the annular groove 2112. At this time, when the knob 24 is rotated, the limiting portion 17 cannot perform the limiting function.

[0042] The electric energy meter 1 also includes a controller, a pressure sensor 18 and a trigger 19. The pressure sensor 18 and the trigger 19 are electrically connected to the controller. The pressure sensor 18 is arranged on the outer wall of the connecting rod 21. When the spring sheet 121 contacts the outer wall of the connecting rod 21, the pressure sensor 18 is subjected to pressure and transmits the pressure signal to the controller. The controller controls the trigger 19 to move rightward (such as Figure 3 As shown in the right side), the trigger 19 abuts against the limiting portion 17 of the limiting member, pushing the limiting portion 17 of the limiting member to move rightward (as shown in the right side). Figure 3 As shown in the right side, the transmission part 16 transmits the power to the button part 15, and the button part 15 is reset. At this time, the knob 24 is rotated, and the limiting part 17 of the limiting member can abut against the knob 24 to limit the rotation of the knob 24.

[0043] This embodiment also provides the working process of the electric energy meter component:

[0044] When installing a new electric energy meter 1, it is operated without power. First, the wire 100 is plugged into the connecting rod 21, and then the connecting rod 21 is inserted into the terminal 12 of the electric energy meter 1, and the spring piece 121 of the terminal 12 can contact the outer wall of the connecting rod 21. The current can be transmitted to the electric energy meter 1 through the wire 100, the connecting rod 21 and the spring piece 121, thereby realizing the electrical connection between the wire 100 and the terminal 12 of the electric energy meter 1. The multiple terminals 12 of the electric energy meter 1 are connected to the auxiliary replacement part 2 in sequence through the above steps to complete the installation of the newly installed electric energy meter 1.

[0045] When the electric energy meter 1 fails and needs to be replaced, first press the button part 15 of the limit part. At this time, the limit part 17 is located at the annular groove 2112. Rotate the knob 24 to allow the other end of the connecting rod 21 to extend into the sleeve 23. Continue to rotate the knob 24. The spring sheet 121 of the terminal 12 of the electric energy meter 1 is lifted up by the insulating part 22 and separated from the connecting rod 21, thereby achieving the power-off effect. At the same time, due to the insulating protection of the insulating part 22 and the sleeve 23, the entire auxiliary replacement part 2 is in a non-powered state. The entire auxiliary replacement part 2 is taken out of the electric energy meter 1. In this way, all the auxiliary replacement parts 2 of the electric energy meter 1 are taken out. Then insert a connecting rod 21 of an auxiliary replacement part 2 into the new electricity meter 1, rotate the knob 24, and partially unscrew the connecting rod 21 out of the sleeve 23, so that the spring sheet 121 of the terminal 12 of the electricity meter 1 contacts with the connecting rod 21, and the electricity meter 1 is energized. When the connecting rod 21 is rotated to make the pressure sensor 18 on the connecting rod 21 contact with the spring sheet 121, the controller controls the trigger 19 to push the limiting part 17 of the limiting part, and the button part 15 is reset, and the knob 24 cannot be rotated, and multiple auxiliary replacement parts 2 are installed one by one at multiple terminals 12 in turn to complete the work of replacing the electricity meter 1.

[0046] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention.
