Description

Technical Field

[0001] This invention relates to the field of electricity meter technology, specifically to an electricity meter with a protection mechanism. Background Technology

[0002] An electricity meter is an instrument used to measure the electrical energy consumed in a circuit. It is also commonly known as an "electricity meter" and is widely used in daily life and power systems. The main function of an electricity meter is to record the electrical energy consumed by electrical appliances over a period of time, which is commonly referred to as "kilowatt-hours" (kWh). For example, if a 1000-watt appliance in a household runs for 1 hour, the electricity meter will record the consumption of 1 kWh. It is the main basis for power companies to calculate electricity bills and also helps users understand their electricity usage.

[0003] Common types of electricity meters include mechanical induction electricity meters, electronic electricity meters, and smart electricity meters. Among them, smart electricity meters, based on electronic electricity meters, add communication modules, storage chips, etc., and have functions such as remote meter reading, time-of-use billing and prepayment, and electricity consumption monitoring. When wiring a smart electricity meter, the control line is connected at the same time as the power line. The control line is mainly used to realize the communication and remote control functions of the electricity meter, and its wiring is independent of the main circuit wiring.

[0004] There are two main operational challenges when installing power and control cables for existing smart meters: First, since most meters are wall-mounted or embedded in meter boxes, workers must precisely align and insert the cables into the terminal holes within a limited space. These holes are typically located at the bottom of the meter, making misalignment easy. Second, after the power and control cables are connected to the meter terminals, the lack of a reliable cable-fixing structure means the cables are prone to shaking due to external pulling or vibration during daily use, potentially leading to poor contact or loose terminals. Summary of the Invention

[0005] Therefore, the purpose of this invention is to provide an energy meter with a protection mechanism to solve the technical problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an energy meter with a protection mechanism, comprising a device housing and an upper cover plate, wherein a lower cover plate for positioning the power line and control line is installed at one end of the device housing, the lower cover plate comprising a fixing block, a first through hole and a second through hole, a first through hole at the top of the fixing block and a second through hole at the lower end of the fixing block, a first positioning groove and a second positioning groove at one end of the device housing, wherein a second limiting plate and a first limiting plate are fixedly installed on the outer walls of the first positioning groove and the second positioning groove, wherein a first pair of interfaces and a second pair of interfaces are provided at one end of the first limiting plate and the second limiting plate, and a partition plate is installed on the top of the second pair of interfaces.

[0007] By adopting the above technical solution, staff can quickly locate the corresponding holes, improving work efficiency and accuracy of wiring. The lower cover plate is fitted over the outer walls of the first and second limiting plates, with a fixing block located on top of the second limiting plate. The first through hole, second threaded hole, and third threaded hole are positioned opposite each other. Bolts are passed through these holes sequentially to position the lower cover plate, and then bolts are passed through the first and second threaded holes for secondary positioning. This improves the stability of the lower cover plate installed at the bottom of the electricity meter, effectively limiting and protecting the power and control lines, and reducing the risk of poor contact or loose terminals between the power line and the electricity meter.

[0008] The present invention is further configured such that a second threaded hole is provided in the middle part of the second limiting plate, and the number of the second threaded holes is two sets, the two sets of the second threaded holes are diagonally distributed, and the second threaded holes are arranged opposite to the first through hole.

[0009] Preferably, the two sets of second threaded holes are diagonally distributed, and their axes (center lines) are perpendicular to each other, which facilitates multi-angle positioning of the lower cover plate.

[0010] The present invention is further configured such that a third threaded hole is provided in the middle part of the first limiting plate, and the third threaded hole is arranged opposite to the second threaded hole.

[0011] Preferably, the position of the lower cover plate is limited by bolts passing through the first through hole, the second threaded hole, and the third threaded hole.

[0012] The present invention is further configured such that a cavity is provided at one end of the second limiting plate near the second positioning groove, and the second positioning groove is sleeved inside the cavity, wherein the second positioning groove and the first pair of interfaces are located on the same horizontal plane.

[0013] Preferably, the position of the second positioning slot is positioned to facilitate the connection of the power cord to the first pair of interfaces.

[0014] The present invention is further configured such that a first threaded hole is provided in the middle part of the fixing block, and the first threaded hole is arranged opposite to a second threaded hole.

[0015] Preferably, the second threaded hole is positioned opposite to the first threaded hole, and then the position of the lower cover plate is fixed again by passing a bolt through the second threaded hole and the first threaded hole.

[0016] The present invention is further configured such that a first through hole is provided at the lower end of the fixing block, and the first through hole is disposed opposite to the second positioning groove and the first interface.

[0017] Preferably, the position of the power cord is effectively limited, thus effectively limiting and protecting the power cord.

[0018] The present invention is further configured such that a connecting block is provided at one end of the partition plate, and multiple sets of sliding grooves are provided at the top of the partition plate.

[0019] Preferably, the slider is fitted inside the groove to effectively limit the position of the connecting pipe.

[0020] The present invention is further configured such that a plurality of connecting pipes are placed on the top of the partition plate, and a slider is provided at the bottom of the connecting pipe, and the slider is sleeved in the groove.

[0021] Preferably, multiple sets of connecting pipes are added to the top of the partition plate to provide secondary protection for the power cord.

[0022] The present invention is further configured such that a protrusion is provided at one end of the connecting pipe near the first pair of interfaces, and the protrusion is in contact with one end of the first pair of interfaces.

[0023] Preferably, one end of the connecting tube is provided with a protrusion, and the protrusion contacts one end of the first pair of interfaces to reduce the phenomenon of power cord leakage.

[0024] In summary, the present invention has the following main beneficial effects: 1. The present invention, through the setting of a first limiting plate and a second limiting plate, which are respectively connected to the first positioning groove and the second positioning groove, makes it easier for workers to quickly find the corresponding hole positions when installing the power line and control line of the electricity meter, thereby improving work efficiency and the accuracy of wiring.

[0025] 2. This invention utilizes a lower cover plate, which is fitted onto the outer walls of the first and second limiting plates. A fixing block is located on top of the second limiting plate. The first through hole, the second threaded hole, and the third threaded hole are arranged opposite each other. The lower cover plate is positioned by bolts passing through the first through hole, the second threaded hole, and the third threaded hole in sequence. Then, bolts are used to perform a secondary positioning of the lower cover plate by passing through the first threaded hole and the second threaded hole in sequence. This improves the stability of the lower cover plate installed at the bottom of the electricity meter, effectively limits and protects the power line and control line, and reduces the risk of poor contact between the power line and the electricity meter or loose terminals.

Then, the bolt is passed through the second threaded hole 6 and the first threaded hole 32 to fix the position of the lower cover plate 3 again.

[0035] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-5 The lower end of the fixing block 31 is provided with a first through hole 33, and the first through hole 33 is positioned opposite to the second positioning groove 9 and the first interface 11, which effectively limits the position of the power cord and effectively limits and protects the power cord.

[0036] Second embodiment: Please see Figure 7 , Figure 8 The difference between Embodiment 2 and Embodiment 1 is that, while retaining the features of Embodiment 1, multiple sets of connecting pipes 10 are added to the top of the partition plate 13 to provide secondary protection for the power cord.

[0037] A partition plate 13 is provided between the first pair of interfaces 11 and the second pair of interfaces 14, and a connecting block 12 is provided at one end of the partition plate 13. The connecting block 12 is engaged with the outer wall of the device housing 1. The surface of the partition plate 13 is provided with a sliding groove 15, and a connecting pipe 10 is placed at the top of the sliding groove 15. A slider 101 is provided at the bottom of the connecting pipe 10, and the slider 101 is fitted inside the sliding groove 15 to effectively limit the position of the connecting pipe 10. A protrusion 102 is provided at one end of the connecting pipe 10, and the protrusion 102 contacts one end of the first pair of interfaces 11 to reduce the phenomenon of power cord leakage.

[0038] In practical operation, this invention: When it is necessary to connect power and control lines to the electricity meter installed on the wall, first remove the upper cover plate 2, lower cover plate 3, multiple sets of connecting pipes 10 and partition plate 13. Then place the control line on the surface of the first limiting plate 4 and place the control line from the second positioning groove 9 into the first positioning groove 5 according to the hole position, and connect it to the second pair of interfaces 14. When the multiple sets of control lines are installed, place the partition plate 13 on the top of the second pair of interfaces 14, and the connecting block 12 engages with the outer wall of the device housing 1 to limit the position of the partition plate 13. Then install the power line. When installing the power line and control line, the staff only needs to observe the position of the second limiting plate 8 and the first limiting plate 4 to install the power line or control line, which effectively improves the efficiency of the installation work. Furthermore, before installing the power cord, after the partition plate 13 is installed, multiple sets of connecting pipes 10 are placed on top of the partition plate 13, and the slider 101 is located in the groove 15 to effectively limit the connecting pipes 10. Secondly, the protrusion 102 fits against the outer wall of the first pair of interfaces 11 to reduce the phenomenon of power cord leakage and effectively protect the power cord. Then, the staff inserts the power cord from the outer wall of the second limiting plate 8 into the second positioning groove 9, and then passes through the connecting pipe 10 to reach the first pair of interfaces 11 and connects with the first pair of interfaces 11. Furthermore, after the power cord and control line are installed, the upper cover plate 2 and the lower cover plate 3 are installed in sequence. The upper cover plate 2 is installed on the outer wall of the device housing 1, and the lower cover plate 3 is installed on the top of the device housing 1. When the lower cover plate 3 is fitted onto the outer wall of the second limiting plate 8, the fixing block 31 contacts the top of the second limiting plate 8 to limit the position of the power cord. At the same time, when the second through hole 34 contacts the top of the first limiting plate 4, it limits the position of multiple sets of control lines. Finally, the position of the lower cover plate 3 is limited by bolts passing through the first through hole 30, the second threaded hole 6, and the third threaded hole 7. There are two sets of second threaded holes 6. The other set of second threaded holes 6 is set opposite to the first threaded hole 32. The position of the lower cover plate 3 is fixed again by bolts passing through the second threaded hole 6 and the first threaded hole 32, thereby protecting and limiting the power cord and control line.
