Description

Technical Field

[0001] This utility model belongs to the field of meter box technology, and specifically relates to a modular meter box. Background Technology

[0002] Electricity meter boxes, also known as meter sets or energy meter enclosures, are essential devices in power systems used to install and protect electricity meters, circuit breakers, air switches, and other components. They are typically installed in residential, commercial, and industrial facilities. Electricity meter boxes are generally classified by casing material (metal and non-metal), phase (single-phase and three-phase), and meter position (single-position and multi-position). Single-position meter boxes are commonly used in rural residential areas, apartments, villas, detached buildings, new energy grid connection, and new energy vehicle charging stations, while multi-position meter boxes are typically used in residential communities, shopping malls, and industrial facilities.

[0003] Traditional electricity meters and components are typically fixed inside electricity metering boxes using screws, clips, or other methods. The meters and components are connected by rigid wires, with screws securing the wires to the internal terminals to establish the electrical connection. Initial installation and replacement of traditional electricity metering boxes and their internal components require installers to simultaneously secure the meters, components, and rigid wires, demanding considerable experience and skill. This process is prone to wiring errors and is time-consuming. When replacing components inside the metering box, the disassembly and reassembly of wires and components require significant time, especially in poor installation conditions, limited space, or scenarios with multiple meters and components, increasing the risk of wiring errors and potential power outages. In practical use, because the outer casing and back panel of the meter box are exposed to the environment for a long time, they are more prone to cracking or damage due to exposure to sunlight or impact compared to electrical components such as electricity meters and circuit breakers. In traditional electricity meter boxes, the electricity meters and components are installed on the back panel. When the back panel is damaged, the electricity meters and components must be disconnected from the power supply and removed before the back panel can be replaced. This power outage due to non-electrical component failure will cause a bad experience for electricity users. Some electricity users may insist on using the damaged meter box because they cannot disconnect the power in the short term due to production requirements, which brings certain production safety risks.

[0004] Therefore, there is a need for an energy metering box structure that can be quickly installed and disassembled at the power installation site to solve the above problems. Utility Model Content

[0036] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0037] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0038] Example 1

[0039] Please see Figures 1-8 As shown, this embodiment is a modular electricity meter box, including a box body 1. The box body 1 is equipped with an electricity metering unit, a transfer unit, and a circuit switching unit. Both the electricity metering unit and the circuit switching unit are provided with electrical connection sockets. The transfer unit is provided with a plug-in part. The plug-in part can be plugged into the electrical connection sockets on both the electricity metering unit and the circuit switching unit to conduct electricity, so as to realize the conductive connection between the electricity metering unit and the circuit switching unit through the plug-in of the transfer unit.

[0040] The adapter also includes a mounting base, which can be detachably connected to the housing 1. The plug-in part, the power metering part, and the circuit switching part can be installed on the mounting base.

[0041] When installing this modular meter box, first, the box body 1 is locked and installed in the corresponding wall position with screws. Then, the adapter is fixed and installed on the mounting base with screws. Next, the energy metering part and the circuit switching part are connected to the plug-in part on the adapter part through the electrical connection socket. The electrical connection between the energy metering part and the circuit switching part is achieved through the plug-in of the adapter part. Finally, the energy metering part and the circuit switching part are locked and installed on the mounting base with screws. Finally, the mounting base is fixed and installed in the box body 1 to complete the installation of the meter box.

[0042] Among them, by setting up a transfer part in the meter box, the transfer and plug-in connection between different electrical components in the meter box can be realized through the transfer part, without the need for external connecting wires, which can simplify the installation process at the power construction site, reduce the installation difficulty, save installation time, and reduce installation costs.

[0043] Specifically, the electricity metering part includes an electricity meter 3, the bottom of which is provided with multiple electricity meter electrical connection sockets 31; the circuit switching part includes a circuit breaker 5, the top of which is provided with multiple circuit breaker electrical connection sockets 51; the plug-in part includes a plug socket 4, the top of which is fixedly installed with multiple upper connecting pins 41 corresponding to the electricity meter electrical connection sockets 31; the bottom of which is fixedly installed with multiple lower connecting pins 42 corresponding to the circuit breaker electrical connection sockets 51; and the corresponding upper connecting pins 41 and lower connecting pins 42 are electrically connected.

[0044] When installing the meter box, the upper connecting pin 41 of the connector 4 is connected to the electrical connection socket 31 at the bottom of the meter 3, and the lower connecting pin 42 of the connector 4 is connected to the electrical connection socket 51 at the top of the circuit breaker 5. Thus, the upper connecting pin 41 and the lower connecting pin 42 can achieve a conductive connection between the meter 3 and the circuit breaker 5 without the need for an external wire to connect the meter 3 and the circuit breaker 5. The circuit breaker 5 is then connected to the power supply circuit through a wire, so that the meter 3 and the circuit breaker 5 can work together to achieve power metering and on / off control of the circuit.

[0045] Furthermore, the circuit switching part can also use an air switch, and the air switch is equipped with a corresponding electrical connection socket.

[0046] Furthermore, in addition to the above-mentioned plug-in connection method, the electricity meter 3, the socket 4, and the circuit breaker 5 (air switch) can also be arranged in a reverse vertical arrangement, with the circuit breaker 5 (air switch) on top and the electricity meter 3 on the bottom. In this case, the electrical connection sockets on the electricity meter 3 and the circuit breaker 5 need to be swapped accordingly. Alternatively, they can be arranged horizontally, with the electricity meter 3 in the middle, and the circuit breaker A connected to the incoming line and the circuit breaker B connected to the outgoing line installed on both sides of the electricity meter 3. In this scheme, there are two sockets 4, and the two sockets 4 are respectively located on both sides of the electricity meter 3. At the same time, the electrical connection sockets and pins are all arranged laterally.

[0047] Furthermore, this embodiment takes a single-phase metering box as an example, but it can also be used for three-phase metering boxes. The reference circuit breaker (air switch) for three-phase metering box special components such as current transformer (CT) and voltage transformer (VT) is equipped with an adapter to form a unit module, which is plugged into the built-in copper busbar back plate.

[0048] Furthermore, this application takes a single-meter meter box as an example, but it can also be used for multi-meter meter boxes with two, four, six, nine, or twelve meters. In the multi-meter meter box, each group of energy meters 3 and circuit breaker 5 (air switch) is equipped with a transfer part to realize the plug-in connection between each group of energy meters 3 and circuit breaker 5 (air switch).

[0049] Specifically, the mounting base includes an adapter backplate 2, which has multiple mounting holes. The adapter backplate 2 can be locked into the interior of the housing 1 through the mounting holes and screws, thus achieving the purpose of detachable connection between the mounting base and the housing 1. The power metering unit and the circuit switching unit can be fixedly installed on the adapter backplate 2 through screws and mounting holes.

[0050] When installing the meter box, the energy metering unit and the circuit switching unit can be fixedly connected to the adapter back plate 2 with screws, and the connection between the energy metering unit and the circuit switching unit can be realized through the plug-in part. Then, the adapter back plate 2, the energy metering unit, the circuit switching part and the plug-in part are installed as a whole in the box 1. Therefore, it is not necessary to install each electrical component in the narrow box 1 one by one, which makes the installation of electrical components in the meter box more convenient.

[0051] Specifically, the corresponding upper connecting pin 41 and lower connecting pin 42 are made by bending the same copper wire, and the adapter back plate 2, the socket 4, the upper connecting pin 41 and the lower connecting pin 42 are integrally injection molded to improve the stability of the overall connection.

[0052] Specifically, the upper end of the adapter back plate 2 is provided with a limiting guide groove 21. The power metering unit can be lifted and slidably mounted in the limiting guide groove 21. When installing the power metering unit, the limiting guide groove 21 is used to slide and guide the power metering unit, which can improve the alignment accuracy of the power metering unit and make the power metering unit and the plug-in part accurately aligned and plugged in.

[0053] Specifically, the lower end of the adapter back plate 2 is provided with a guide rail 6. The circuit switching part can be slidably mounted on the guide rail 6 through the waist-shaped hole on the back. Both ends of the guide rail 6 are provided with adjustment grooves 61. The guide rail 6 is locked onto the adapter back plate 2 by screws passing through the adjustment grooves 61, and the guide rail 6 can be adjusted up and down along the screws through the adjustment grooves 61.

[0054] The guide rail 6 is a DIN rail. When installing the circuit switching part, the circuit switching part can be clamped onto the DIN rail through the waist-shaped hole. Then, the screw is passed through the upper end of the adjustment groove 61 to initially install the DIN rail onto the adapter back plate 2. Then, the DIN rail is pushed upward under the limit of the screw so that the electrical connection socket at the upper end of the circuit switching part is connected to the upper plug-in part. Then, the screw is tightened to lock the DIN rail and the circuit switching part onto the adapter back plate 2.

[0055] Specifically, a cover 11 is fixedly installed at the front opening of the enclosure 1 by screws. An operation window 13 is provided on the cover 11, located in front of the circuit switching part. A window cover 12 is rotatably installed inside the operation window 13 via a pin.

[0056] The box body 1 and the box cover 11 are made of plastic or metal materials. The box cover 11 is provided with a transparent window located in front of the display position of the power metering section. By providing the operation window 13, the circuit can be switched on or off through the operation window 13 without opening the box cover 11.

[0057] Furthermore, the lower end of the box 1 is provided with an opening slot 14 for the routing of the incoming and outgoing lines outside the meter box. The incoming and outgoing lines are connected to the circuit switching part inside the meter box through the opening slot 14. The opening slot 14 is located on one side of the box cover 11 and is designed to be open. When the box 1 needs to be replaced due to rust or aging, without interrupting the power supply, remove the screws fixing the adapter back plate 2. Under the premise of taking safety precautions (wearing insulating clothing and insulating gloves), remove the adapter back plate 2, the energy metering part, the circuit switching part, and the plug-in part as a whole. The incoming and outgoing lines are separated from the box 1 through the opening slot 14. After replacing the new meter box 1, put the adapter back plate 2, the energy metering part, the circuit switching part, and the plug-in part back into the box 1 as a whole and install the screws. This allows the replacement of the box 1 without interrupting the power supply, making the replacement of the box 1 more convenient and preventing the power outage caused by non-electrical component failures from causing a bad experience for the power users.

[0058] Furthermore, the connection ends of the incoming and outgoing lines are equipped with aviation plugs (not shown in the figure), and the incoming and outgoing lines are connected to the circuit switching part through the aviation plugs. At the same time, the aviation plugs are sealed in the opening slot 14. By sealing the opening slot 14, the sealing performance of the box 1 can be improved, thereby improving the waterproof and dustproof effect of the meter box.
