[0001] The invention relates to the technical field of electric energy metering boxes, and in particular to an electric energy metering box with a modular structure. Background Art

[0002] The power meter box is a device used for power metering, distribution and protection in power systems. It is widely used in residential, commercial buildings, industrial facilities and other fields. The main function of the power meter box is to ensure the safety and reliability of power supply, accurately measure the user's power consumption, and provide a basis for electricity bill settlement.

[0003] The Chinese utility model patent with application number CN212462499U discloses an electric energy meter box, which belongs to the technical field of electric power metering equipment. The electric energy meter box includes a box door side and an installation side. The first box body and the second box body are spliced ​​to form the electric energy meter box.

[0004] The modular electric energy meter box of the prior art mainly sets the circuit board as a modular structure, and realizes the modular installation of the electric energy box by splicing each other.

For customers who have a preference for the installation position of home decoration, this structure is not convenient for adjusting the position of the electric energy meter. At the same time, in order to take into account the transmission of the line, the modular installation needs to install the electric energy meter, switch and line in a specific position, which will make it impossible to implement the subsequent optimization measures of wiring and heat dissipation layout.

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose an electric energy metering box with a modular structure.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] An electric energy metering box with a modular structure comprises a box body and also comprises:

[0008] An adjustable modular electricity meter, the adjustable modular electricity meter comprising a back plate, mounting plates are fixedly mounted on both sides of the back plate, mounting nuts are arranged around the mounting plates, a thread groove is arranged inside the mounting plate, a first bracket is arranged on the surface of the thread groove, a first screw is arranged on one side of the first bracket, and the first screw is screwed and mounted inside the thread groove;

[0009] A first modular skateboard is suspended in the middle part of the first bracket, a slide groove is provided on one side of the first modular skateboard, a first conductive ring is installed around the inside of the slide groove, an electricity meter is slidably docked and installed on one side of the slide groove, an electricity meter connector is provided on one side of the electricity meter, and the electricity meter connector is slidably arranged on the surface of the first conductive ring, a slot hole is provided on one side of the first modular skateboard, a pad is installed on the surface of the slot hole, a locking piece is provided inside the pad, and the locking piece is screwed and pressed on one side of the electricity meter, a cylinder bracket is provided on one side of the first modular skateboard, a cylinder is provided on one side of the cylinder bracket, and an output end of the cylinder is connected to one side of the electricity meter.

[0010] According to a further technical solution, a surface array of the back plate is provided with heat dissipation grooves.

[0011] Further technical solutions include:

[0012] Modular split switch: The modular split switch includes a split cable and a modular switch; the modular switch:

[0013] The modular switch includes a second bracket mounted on the surface of the thread groove, a second screw is arranged inside the second bracket, and the second screw is screwed and installed inside the thread groove. A second modular slide is mounted on one side of the second bracket, and the longitudinal section of the second modular slide is also an "I"-shaped structure. A switch is slidably arranged on the surface of the second modular slide, and a knife is arranged on one side of the switch. A second conductive ring is installed around the surface of the "I"-shaped structure.

[0014] A further technical solution is that the split cable arrangement includes a first node and a second node respectively connected to one side of the first conductive ring and the second conductive ring, and the ends of the first node and the second node are provided with a first bottom plate, a power connection ring and a second bottom plate, and a second power connection ring, and the power connection ring and the second power connection ring are internally connected and installed with wires, and an expansion joint is provided in the middle of the wire.

[0015] According to a further technical solution, the expansion joint is a part of the conductor and is made of a conductive material.

[0016] According to a further technical solution, one side of the first modular skateboard is conductively connected to a first electric ring, an input line is connected inside the first electric ring, and one side of the second modular skateboard is conductively connected to a second electric ring, an output line is arranged inside the second electric ring.

[0023] Through the split cable structure, the conductive cable is split and arranged on the side of the main electrical appliance. This arrangement can prevent the cable from interfering with the main electrical appliance during the arrangement. At the same time, the expansion joint on the surface of the cable can be adaptively expanded and contracted to avoid the problem of length mismatch during the installation process. The split cable arrangement makes the cable arrangement of the device more neat and beautiful.

The fan blows air into the inside of the box by blowing air, achieving the heat dissipation effect of the entire parts. Due to the modular structure, the installation position can be arranged arbitrarily. The air duct airflow inside the box has a better heat dissipation effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] In the electric energy metering box with a modular structure, the adjustable modular electricity meter 2 and the modular split switch 3 are arranged in parallel with each other to ensure that the device will not be deflected or damaged during movement.

[0046] Working principle:

[0047] In the actual design process of the present invention, in order to avoid the following technical defects existing in the electric energy meter box in the prior art: "The modular electric energy meter box in the prior art mainly sets the circuit board as a modular structure, and realizes the modular installation of the electric energy box by splicing each other. However, this splicing method makes it difficult to adjust the position of the electric energy meter after fixing. For customers who have a preference for the installation position of home decoration, this structure is not convenient for adjusting the position of the electric energy meter. At the same time, in order to take into account the transmission of the line, the modular installation needs to install the electric energy meter, switch and line in a specific position, which will make it impossible to implement the subsequent optimization measures of the wiring and heat dissipation layout.", an adjustable modular electric energy meter 2, a modular split switch 3 and a split wiring are specifically proposed;

[0048] Adjustable Modular Power Meter 2:

[0049] The adjustable modular electricity meter 2 of the present invention improves the traditional modular electricity meter 13 plug-in structure. The traditional modular docking method is improved to a method of docking between local modular and adjustable structures. The first modular skateboard 9 is modularly plugged and installed inside the mounting plate 7 through the first bracket 11 and the first screw 12 on the side. This follows the advantages of modular installation. However, in order to achieve easy adjustment of the installation position of the electricity meter 13, we set the first modular skateboard 9 as a slide structure. An "I"-shaped skateboard structure is provided inside the first modular skateboard 9, which is plugged into the meter connector 21 of the electricity meter 13 by sliding with each other, so as to achieve the sliding effect of the electricity meter 13. When the installation position of the electricity meter 13 is adjusted, the electricity meter 13 is fixed to the surface of the first modular skateboard 9 by the pad 14 and the locking member 15, thereby achieving a stable fixation effect.

[0050] The reason why the present invention converts the fixed modular electric meter installation structure into a modular, mobile and mutually docking method is mainly to take into account the installation position preference of the electric meter 13 during the home decoration process, and at the same time to achieve a reasonable layout of the electrical appliance positions inside the electric meter box, thereby having certain advantages in terms of heat dissipation, wiring and current stability.

[0051] Modular Split Switch 3:

[0052] The modular split switch 3 includes two parts: a split cable and a modular switch. The structural principle of the modular switch is consistent with the principle of the adjustable modular electricity meter 2. Its main structure is a second modular slide plate 16, which is modularly mounted inside the thread groove 8 of the mounting plate 7 through a second bracket 18 and a second screw 19. The surface of the second modular slide plate 16 is also provided with an "I"-shaped structure, and the switch 17 is mounted on the surface of the structure by docking. The modular installation and sliding effect of the switch 17 can be achieved. The knife 24 on the surface of the switch 17 is a component for realizing the opening and cutting off of the circuit.

[0053] Split cable:

[0054] The split cable arrangement is a structure in which the cables are set separately. The first bottom plate 25 and the second bottom plate are set on one side of the electricity meter 13 and the switch 17 respectively, and the first conductive ring 20 and the second conductive ring 1601 are sleeved on the sliding part of the electricity meter 13 and the switch 17, and the current is guided to the part of the power ring 27 through the first node 26 and the second node 30 to realize the connection of the circuit. The inside of the power ring 27 is connected through the wire 28, and the expansion joint 29 is set in the middle section of the wire 28 to adjust the length of the wire 28 so that the wire 28 will not have mismatching problems during the installation process. The input line 23 connected to one side of the first electric ring 22 is the current input part, and the output line 32 installed inside the second electric ring 31 is the current output part.

[0055] The overall line direction of the device is input line 23-electricity meter 13-first wire ring 20-wire 28-second conductive ring 1601-switch 24-output line 32; the overall current flow direction is from top to bottom to achieve current transmission. The remaining components are modularly installed inside the mounting plate 7 by plugging the first bracket 11, the first screw 12; the second bracket 18 and the second screw 19.

[0056] Auxiliary structures:

[0057] In order to achieve auxiliary heat dissipation effect and avoid overheating and dust accumulation inside the device, we set an outer box 34 in the top array of the box 1, and the fan 35 installed in the inner plug of the outer box 34 continuously blows air into the inside of the box 1, thereby achieving the effect of heat dissipation and cooling of internal components.

[0058] In addition, the expansion joint 29 provided in the middle of the conductor 28 is a structure to ensure the expansion and contraction of the conductor 28, and can ensure the expansion and contraction effect of the conductor 28 during the installation process.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
