Description

Technical Field

[0001] This utility model relates to a multi-user smart energy meter that is easy to wire, and belongs to the field of smart energy meter technology. Background Technology

[0002] Smart meters are modern energy metering devices with high accuracy, remote communication, and data analysis capabilities, widely used in homes, industry, and commerce. They employ electronic metering technology, resulting in low error (typically ±0.5% to ±1%), support bidirectional metering (suitable for scenarios such as photovoltaic power generation), and enable automatic data upload via RS-485, PLC (power line carrier), or wireless modules (such as 4G / NB-IoT). They also support remote meter reading and cost control, and time-of-use billing, recording electricity consumption at different times to optimize electricity costs in conjunction with tiered pricing policies.

[0003] A smart meter is a device that measures electricity consumption. It can monitor electricity consumption by connecting the meter to the line. Most existing wiring is done using terminals. However, due to insufficient compression between the metal wire and the terminal, poor wiring may occur. While wrapping the metal wire can solve the problem of poor contact, it is inconvenient to operate and increases the difficulty of operation for construction workers. Utility Model Content

[0028] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0029] like Figure 1-3 As shown, the convenient wiring multi-user smart energy meter includes:

[0030] The electricity meter housing 1 has multiple wiring structures fixedly installed at one end. Each wiring structure consists of a connector 5, a pressure sleeve 9, a top cover 17, and a screw 18. The pressure sleeve 9 is movably sleeved on the surface of the connector 5. A connecting wire 4 is wound around the surface of the connector 5 below the pressure sleeve 9. The bottom surface of the pressure sleeve 9 has a winding structure and a pressing structure on the inside and outside, respectively. The top cover 17 is located above the pressure sleeve 9. A screw 18 is inserted through the middle of the top cover 17 and is threadedly connected to the inside of the connector 5.

[0031] The electricity meter housing 1 has multiple evenly distributed wiring structures on one side, and all wiring structures are located inside the housing cover 2. The housing cover 2 is rotatably connected to the electricity meter housing 1, and the housing cover 2 is fixedly connected to the electricity meter housing 1 by a latch 3. The edge of the housing cover 2 is provided with a notch for the lead-out of the connecting wire 4.

[0032] In this technical solution, the wiring structure is protected by the cover 2. After the latch 3 is opened, the wiring operation is performed. After completion, the cover 2 is closed, and the connecting wire 4 is led out through the notch on the edge of the cover 2.

[0033] The connector 5 is fixedly installed on the surface of the electricity meter housing 1. The top of the connector 5 is provided with a socket 6. The connector 5 located in the middle of the socket 6 is provided with a threaded hole 7. The connector 5 is connected to the screw 18 through the threaded hole 7. A conductive sheet 8 is fixedly connected to the surface of the connector 5. A collar 20 is fitted and rotated on the outer surface of the connector 5. The collar 20 is correspondingly arranged above the conductive sheet 8.

[0034] In this technical solution, the connecting wire 4 is fixed through the connector 5, and the threaded hole 7 is provided for fixing the screw 18. The pressure sleeve 9 can be pressed against the surface of the connector 5. The connection wire 4 is pressed and fixed by the cooperation of the pressure sleeve 9 and the connector 5, so that the metal part of the connecting wire 4 is in close contact with the conductive sheet 8, ensuring the stability of the wiring.

[0035] The winding structure consists of a spring 10 and a lever 11. The spring 10 is located inside the bottom end of the pressure sleeve 9. The pressure sleeve 9 is connected to the lever 11 through the spring 10. The lever 11 is movably inserted into the pressure sleeve 9. The lever 11 is correspondingly located on one side of the collar 20, and the side of the lever 11 near the collar 20 is provided with an inclined surface 12. The lever 11 is correspondingly located above the conductive sheet 8, and a connecting line 4 is provided between the lever 11 and the collar 20.

[0036] In this technical solution, during the wiring process, one end of the connecting wire 4 is placed on the surface of the connector 5. After pressing the pressure sleeve 9, the lever 11 is moved down. The inclined surface 12 of the lever 11 contacts the connecting wire 4 and presses it against the surface of the collar 20. At this time, the pressure sleeve 9 is rotated on the connector 5 to make the clamped connecting wire 4 rotate around the collar 20, thereby winding the connecting wire 4 to increase the metal contact area.

[0037] The clamping structure consists of a pressure ring 13 and guide rods 15. The pressure ring 13 is sleeved with the edge of the pressure sleeve 9. Multiple evenly distributed guide rods 15 are fixedly connected to the top surface of the pressure ring 13. Each guide rod 15 is inserted through the inside of the pressure sleeve 9. A groove 14 is opened on one side of the bottom of the pressure ring 13, and the pressure ring 13 is distributed correspondingly to the edge of the connector 5. A screw cap 16 is threadedly connected to the top of the pressure sleeve 9. The screw cap 16 is fitted and connected to the top surface of the pressure sleeve 9, and the screw cap 16 contacts the multiple guide rods 15.

[0038] In this technical solution, multiple guide rods 15 can be pressed by rotating the cap 16, so that the guide rods 15 drive the pressure ring 13 to press against the edge of the connector 5. The groove 14 is provided for the lead-out of the connecting wire 4, so as to achieve tight pressing and fixation, and avoid the problem of loosening of the connecting wire 4, thereby improving the wiring stability.

[0039] The top cover 17 has an inner cavity 19, which is distributed correspondingly to the top of the connector 5. The top cover 17 located outside the inner cavity 19 contacts the pressure sleeve 9, and the top cover 17 located inside the inner cavity 19 is fitted and inserted into the socket 6.

[0040] In this technical solution, when the screw 18 is tightened, the screw 18 presses the top cover 17 onto the pressure sleeve 9. The outer edge of the top cover 17 presses the pressure sleeve 9, and the internal insertion into the socket 6 achieves a stable connection. When the pressure sleeve 9 presses onto the connecting wire 4, it causes the lever 11 to extend and retract inward, so that the lever 11 is not affected by the thickness of the connecting wire 4 after it is wrapped, and the pressure sleeve 9 can effectively press and fix the connecting wire 4.

[0041] This utility model is not limited to the above-described embodiments. Any changes in its shape or structure fall within the protection scope of this utility model. The protection scope of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
