Description

Technical Field

[0001] This patent relates to a power distribution meter, and in particular to a new type of power distribution meter. Background Art

[0002] The power distribution meter is an instrument that can be used to measure various electrical quantities. When using the power distribution meter, please note that in the case of low voltage (no more than 500 volts) and small current (tens of amperes), the power distribution meter can be directly connected to the circuit for measurement. In the case of high voltage or high current, the power distribution meter cannot be directly connected to the line and must be used in conjunction with a voltage transformer or a current transformer.

[0003] Traditional power distribution instruments cannot be easily connected to external devices, such as maintenance equipment, inspection equipment, debugging equipment, etc., for quick and effective connection, which is very inconvenient during installation and debugging.

[0004] At the same time, traditional power distribution meters have different shell sizes because they need to adapt to different scenarios. In the traditional method, the corresponding circuit boards also need to be set in different sizes to match the corresponding shells, resulting in an increase in production costs and R&D costs.

[0005] Traditional power distribution meters are basically fixed in configuration and cannot be easily upgraded.

[0006] Traditional power distribution meters require three circuit boards to set up corresponding transformers, terminals, chips, etc., which are thick and costly. Summary of the invention

[0007] The purpose of this disclosure is to propose a new type of power distribution meter, which can solve at least one of the above technical problems. The technical solution of this patent is as follows:

[0008] A novel power distribution meter comprises a shell and a circuit board. The shell comprises a bottom shell and a panel. The panel is provided with a coding identification area, and the circuit board is provided with a Bluetooth module.

[0009] The beneficial effect is that after setting the coding identification area, the external device can quickly connect the power distribution meter with the external device through the Bluetooth module by scanning the corresponding coding identification area. This makes it convenient to repair or inspect equipment, debug equipment, etc. At the same time, communication connection can be carried out through the Bluetooth module, which makes it convenient to perform remote upgrades (OTA) and other operations.

[0010] In some embodiments, an identification code is provided on the coding identification area, and the identification code is configured to uniquely correspond to the Bluetooth module.

[0011] The beneficial effect is that the identification code is configured to correspond uniquely to the Bluetooth module, so that it can be quickly connected to the Bluetooth module of the power distribution meter.

[0012] In some embodiments, mounting positions are provided on the bottom shell and / or the panel, and the bottom shell and / or the panel of the housing include several different sizes, and the spacing between the mounting positions on the bottom shells and / or panels of different sizes is the same to adapt to circuit boards of the same size.

[0013] The beneficial effect is that by setting the same spacing of mounting positions in shells of different sizes, different sizes of appearances can be adapted to the same size of circuit boards. In this way, distribution meters of different sizes only need to replace shells of different sizes, and the circuit boards can use the same circuit board, which greatly reduces production costs.

[0014] In some embodiments, a Bluetooth indicator light is provided on the panel, and the Bluetooth indicator light is configured to light up when an external device is connected to the power distribution meter via Bluetooth.

[0016] In some embodiments, an LED electronic screen interface and a liquid crystal display screen interface are provided on the circuit board. The LED electronic screen interface is configured to be connected to the LED electronic screen, and the liquid crystal display screen interface is configured to be connected to the liquid crystal display screen.

[0017] The beneficial effect is that the circuit board is provided with both an LED electronic screen interface and an LCD display interface, so that the versatility of the circuit board can be achieved. Regardless of whether the user of the power distribution meter needs an LED electronic screen or an LCD display, the same circuit board can be directly used. It only needs to connect the corresponding screen to the corresponding interface, and the overall versatility is stronger.

[0018] In some implementations, an extended communication interface is provided on the circuit board, and the extended communication interface is configured to connect to an external expansion device.

[0019] The beneficial effect is that after the extended communication interface is provided, the extended communication interface can be conveniently used to connect to the external expansion device to carry out corresponding function expansion, without the need to make corresponding improvements to the circuit board, and the function expansion is more convenient. At the same time, remote communication connection can also be carried out through the extended communication interface, so that remote upgrade (OTA) and other operations can be conveniently carried out.

The hook body is provided on the main body, and the connecting arm is provided on the side of the main body and extends outward.

[0021] The beneficial effect is that after setting the connecting buckle, when the entire distribution meter is installed in the electrical box or the mounting hole, the hook body can directly hook the side wall of the mounting hole, and the connecting arm can be clamped in the mounting hole, thereby achieving good fixation of the distribution meter and preventing it from falling off.

[0022] In some embodiments, a terminal and transformer assembly is provided on the circuit board, and the terminal and transformer assembly includes a transformer body, a terminal body and a U-shaped copper wire. The transformer body is provided in several groups and is spaced apart on one side of the circuit board; the terminal body is provided in several groups and is stacked on top of the transformer body respectively; the U-shaped copper wire is matched with the transformer body, and the end of the U-shaped copper wire is connected to the corresponding terminal body; the terminal body is connected to the circuit to be measured, and the U-shaped copper wire can transfer current or voltage proportionally to the transformer body through electromagnetic induction.

[0023] The beneficial effect is that by integrating the terminal and the transformer structure into the circuit board, the overall thickness of the distribution meter is greatly compressed, the volume requirement of the distribution meter is reduced, and the traditional three circuit boards are compressed to only one circuit board, and the overall thickness and cost are greatly reduced.

[0024] In some embodiments, the terminal and transformer assembly also includes a first fixing frame and a second fixing frame, the first fixing frame is installed above the transformer body, including two vertical plates located on both sides and a cover plate located on the top, and the bottom surface of the cover plate is abutted against the top of the transformer body; the first clamping member and the second clamping member for clamping the transformer body are respectively arranged on both sides of the cover plate, and a plurality of slots are opened on the cover plate, which are used to realize the connection between the U-shaped copper wire and the terminal body.

[0025] The first clamping member is provided with a plurality of vertical grooves at intervals, and the vertical grooves are used to assemble and fix the two ends of the U-shaped copper wire;

[0026] A plurality of positioning members are arranged below the cover plate, and the lower edges of the positioning members abut against the outer wall of the transformer body;
