Single-phase electronic fee-controlled smart watt-hour meters are smart terminals for smart grids. They are no longer watt-hour meters in the traditional sense. In addition to the basic electricity consumption metering functions of traditional watt-hour meters, in order to adapt to the use of smart grids and new energy, smart meters also have two-way multi-rate metering functions, user-side control functions, two-way data communication functions with multiple data transmission modes, and anti-electricity theft functions.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In the present invention, two phase connection terminals and two neutral connection terminals at the bottom of the electric energy meter body are respectively inserted into two conductive horizontal plates, and the conductive horizontal plates are squeezed so that the insulating partition at the bottom separates the two conductive slides. At this time, the power supply state is that the input phase line is connected to the conductive seat through the conductive connecting rod, the conductive seat is connected to the conductive horizontal plate through the conductive column, the conductive horizontal plate is connected to the phase connection terminal, and the other phase connection terminal is connected to the conductive column through the conductive horizontal plate, and the conductive column is connected to the output phase line through the conductive seat and the conductive connecting rod. Similarly, the input neutral line is connected to the output neutral line through the electric energy meter body. At this time, the electric energy meter body is in a monitoring state; when the electric energy meter body is removed, the phase connection terminal and the neutral connection terminal are separated from the conductive horizontal plate, and the conductive connection terminal is disconnected from the conductive horizontal plate. The conductive cross plate and the insulating partition are driven to move upward by the supporting action of the two springs 1. When the insulating partition is separated from the two conductive slides, the two relative springs 2 will squeeze the two conductive slides, so that the two conductive slides are in contact and the purpose of conducting is achieved. At this time, the conductive line is the input phase line connected with the conductive slide through the bracket, the conductive connecting rod and the conductive seat. Since the two conductive slides are in contact, the output phase line can be connected with the input phase line. Similarly, the input neutral line can be connected with the output neutral line. From the above, it can be seen that even after the main body of the electric energy meter is removed, the purpose of connecting the input phase line with the output phase line and the input neutral line with the output neutral line can still be achieved. There is no need to perform a power outage operation, which will not affect the normal power consumption of users and improve user service satisfaction.

[0018] 2. In the present invention, a bracket is provided to place the main body of the electric energy meter so that the main body of the electric energy meter is located in the frame. After the installation of the main body of the electric energy meter is completed, the threaded barrel is rotated forward so that the two screws are close to each other while the threaded barrel is rotating, so that the two screws drive the two clamping plates to approach each other through the two side plates respectively, and the clamping plates are in contact with the top of the main body of the electric energy meter. Since the top of the clamping plate is inclined, the main body of the electric energy meter can be fixed by means of inclined surface extrusion, abandoning the traditional installation method of using multiple screws. When removing the main body of the electric energy meter, the threaded barrel is rotated in the opposite direction. Similarly, the two clamping plates are moved away from each other, and the main body of the electric energy meter can be removed, which greatly improves the convenience of disassembling and assembling the main body of the electric energy meter, reduces the workload and improves the work efficiency.

[0019] 3. In the present invention, two phase connection terminals and two neutral connection terminals are respectively inserted into two conductive horizontal plates, and the main body of the electric energy meter is positioned by plugging. When the main body of the electric energy meter is disassembled and assembled, there is no need to repeatedly connect the wires on the main body of the electric energy meter, thereby improving the convenience of assembling the main body of the electric energy meter. In addition, only two protruding parts of the conductive horizontal plate have a conductive function, which can achieve the purpose of connecting the phase connection terminal and the neutral connection terminal, the conductive horizontal plate, and the conductive column, and will not cause the direct connection between the phase connection terminal and the neutral connection terminal, thereby improving the accuracy of the electric energy meter monitoring. In addition, the heat dissipation net behind the bracket can continuously discharge the internal heat to prevent safety hazards caused by overheating. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0029] like Figure 1-7 As shown, the present invention provides a technical solution: a single-phase electronic intelligent electric energy meter, comprising an electric energy meter body 1, wherein two phase line connection terminals 2 and two neutral line connection terminals 3 are respectively arranged on both sides of the bottom of the electric energy meter body 1, and the two phase line connection terminals 2 and the two neutral line connection terminals 3 are respectively inserted into two conductive horizontal plates 501, and the electric energy meter body 1 is positioned by plugging, and when the electric energy meter body 1 is disassembled and assembled, there is no need to repeatedly connect the electric energy meter body 1, thereby improving the convenience of assembling the electric energy meter body 1.

[0030] The bottom of the electric energy meter body 1 is overlapped with the bracket 4, the two phase line connection terminals 2 and the two neutral line connection terminals 3 pass through the bracket 4 and are respectively clamped on the sliding assembly 5, two heat dissipation nets 18 are provided on the back of the bracket 4, the bottom of the bracket 4 is fixed to the mounting seat 23, and two mounting holes are provided on both sides of the mounting seat 23. Because of the heat dissipation net 18, the internal heat can be continuously discharged to prevent safety hazards caused by overheating.

[0031] A frame 24 is fixed on the bracket 4, the electric energy meter body 1 is located in the frame 24, and mounting components 25 are provided on both sides of the top of the frame 24. The mounting components 25 overlap the top of the electric energy meter body 1, and the mounting components 25 include two fixing frames 251, and the two fixing frames 251 are fixedly connected to the frame 24. The two fixing frames 251 are connected to the same threaded barrel 253 through two bearings 252. The threaded barrel 253 is internally threaded with two screw rods 254, and the thread directions of the two screw rods 254 are opposite. The ends of the two screw rods 254 that are away from each other are fixedly connected to side plates 255, and the opposite surfaces of the two side plates 255 are provided with clamping plates 256. The two clamping plates 256 pass through the frame 24 and overlap with the top of the electric energy meter body 1. The bottom of the clamping plate 256 is designed to be inclined. Since the thread directions of the two screw rods 254 are opposite, when the threaded cylinder 253 is rotated, the two screw rods 254 can move away from or approach each other, which is convenient for synchronous adjustment of the positions of the side plates 255 and the two clamping plates 256, thereby improving the convenience of disassembly and assembly of the electric energy meter body 1. Since the clamping plate 256 is provided, the clamping plate 256 contacts the top of the electric energy meter body 1. Since the top of the clamping plate 256 is designed to be inclined, the electric energy meter body 1 can be fixed by means of inclined surface extrusion, thereby greatly improving the convenience of disassembly and assembly of the electric energy meter body 1.

[0032] Conductive columns 6 are provided on both sides of the bottom of the sliding component 5. The sliding component 5 includes a conductive horizontal plate 501. The conductive horizontal plates 501 on both sides are respectively connected with two phase connection terminals 2 and two neutral connection terminals 3. Springs 504 are fixed on both sides of the bottom of the conductive horizontal plate 501. The bottom ends of the two springs 504 are fixed to the conductive seat 8. An insulating partition 502 is fixed to the bottom of the conductive horizontal plate 501. A smooth layer 503 is provided on the outside of the insulating partition 502. Because the spring 504 is provided, the conductive horizontal plate 501 and the insulating partition 502 are driven by the support of the two springs 504. Move upward to separate the insulating partition 502 from the two conductive slides 901, so that the insulating partition 502 does not contact the conductive slide 901 when the conductive cross plate 501 is not subjected to force, thereby not affecting the normal movement of the two conductive slides 901. Since the conductive cross plate 501 is provided, only the two protruding parts of the conductive cross plate 501 have a conductive function, which can achieve the purpose of connection between the phase line connection terminal 2 and the neutral line connection terminal 3, the conductive cross plate 501, and the conductive column 6, and will not cause the phase line connection terminal 2 and the neutral line connection terminal 3 to be directly connected, thereby improving the monitoring accuracy of the electric energy meter.

[0033] Two slide grooves 17 are provided on both sides of the bracket 4, and the conductive cross plate 501 is slidably connected in the two slide grooves 17. The bottom of the conductive cross plate 501 is fixed to the two conductive pillars 6, and the two conductive pillars 6 are respectively clamped in the two sockets 10, and the sockets 10 are provided on the conductive seat 8. Through the mutual cooperation between the conductive pillars 6 and the sockets 10, when the conductive pillars 6 are clamped into the sockets 10, the conductive pillars 6 and the conductive seat 8 can be connected. At the same time, the sockets 10 play a role in limiting the conductive pillars 6 to prevent the conductive pillars 6 from shifting their positions and affecting the normal conduction of the circuit.

[0034] The conductive column 6 is connected with a conductive sleeve 7, and the two conductive sleeves 7 are both clamped on the sliding component 5. The two conductive columns 6 are located in the conductive seat 8, and the conductive seat 8 is fixed to one side of the bracket 4. The two conductive seats 8 are close to each other. The sides are provided with a telescopic conductive component 9, and the opposite surfaces of the two telescopic conductive components 9 are overlapped with the sliding component 5 respectively. The telescopic conductive component 9 includes a conductive slide 901, which slides in the conductive seat 8. The opposite surfaces of the two conductive slides 901 are overlapped with the two sides of the smooth layer 503 respectively. The side of the conductive slide 901 away from the smooth layer 503 is connected to the support baffle 90 through two springs 902. The three phases are fixed, and the top of the support baffle 903 is fixedly connected to the bottom of the conductive seat 8. Because an insulating partition 502 is provided, the conductive cross plate 501 allows the insulating partition 502 at the bottom to separate the two conductive slides 901, so that the two conductive slides 901 are not connected. At this time, the power supply state is that the input phase line 19 is connected to the conductive seat 8 through the conductive connecting rod 12, thereby improving the convenience of power switching; because a spring 2 902 is provided, when the insulating partition 502 is separated from the two conductive slides 901, the two opposite springs 2 902 will squeeze the two conductive slides 901, so that the two conductive slides 901 are in contact and the purpose of connecting and conducting is achieved.

[0035] A conductive connecting rod 12 is connected to the front of the conductive seat 8, and an insulating protective sleeve 11 is connected to the outer shell of the conductive connecting rod 12. The insulating protective sleeve 11 is clamped on the front of the bracket 4. A bracket 13 is fixed to the end of the conductive connecting rod 12 away from the conductive seat 8, and a pressure block 14 is provided above the bracket 13. Because the insulating protective sleeve 11 is provided and the conductive connecting rod 12 passes through the bracket 4, the insulating protective sleeve 11 can play a role of insulation protection to prevent safety accidents caused by leakage.

[0036] A fastening screw 15 is connected to the top of the pressing block 14, and the fastening screw 15 is threadedly connected to the wiring barrel 16. The wiring barrel 16 is fixed to the front of the bracket 4. The four wiring barrels 16 on the front of the bracket 4 are respectively provided with an input phase line 19, an output phase line 20, an input neutral line 21 and an output neutral line 22, and the input phase line 19, the output phase line 20, the input neutral line 21 and the output neutral line 22 are respectively located between the pressing block 14 and the bracket 13. The opposing surfaces of the pressing block 14 and the bracket 13 are provided with anti-slip textures. Through the mutual cooperation between the pressing block 14 and the bracket 13, the pressing block 14 and the bracket 13 are both arc-shaped in design and are provided with anti-slip textures inside. In the process of clamping the line, it can play a good anti-slip effect to prevent the line from detaching and causing poor contact.

[0037] The working principle of the present invention is:

[0038] When in use, the input phase line 19, the output phase line 20, the input neutral line 21 and the output neutral line 22 are respectively connected to the four wiring barrels 16, and the clamping block 14 is pressed tightly against the line by rotating the tightening screw 15, and the two phase line connection terminals 2 and the two neutral line connection terminals 3 at the bottom of the electric energy meter body 1 are respectively inserted into the two conductive horizontal plates 501, and the conductive horizontal plates 501 are squeezed so that the insulating partition 502 at the bottom separates the two conductive slide plates 901;

[0039] At this time, the power supply state is that the input phase line 19 is connected to the conductive seat 8 through the conductive connecting rod 12, the conductive seat 8 is connected to the conductive horizontal plate 501 through the conductive column 6, the conductive horizontal plate 501 is connected to the phase line connection terminal 2, and the other phase line connection terminal 2 is connected to the conductive column 6 through the conductive horizontal plate 501, and the conductive column 6 is connected to the output phase line 20 through the conductive seat 8 and the conductive connecting rod 12. Similarly, the input neutral line 21 is connected to the output neutral line 22 through the electric energy meter body 1. At this time, the electric energy meter body 1 is in the monitoring state;

[0040] When the electric energy meter body 1 is removed, the phase connection terminal 2 and the neutral connection terminal 3 are separated from the conductive horizontal plate 501, and the conductive horizontal plate 501 and the insulating partition 502 are driven to move upward by the support of the two springs 1 504. When the insulating partition 502 is separated from the two conductive slide plates 901, the two opposite springs 2 902 will squeeze the two conductive slide plates 901, so that the two conductive slide plates 901 are in contact and the purpose of conducting is achieved;

[0041] At this time, the conductive line is that the input phase line 19 is connected to the conductive slide plate 901 through the bracket 13, the conductive connecting rod 12, the conductive seat 8, and the output phase line 20 can be connected to the input phase line 19 due to the contact between the two conductive slide plates 901. Similarly, the input neutral line 21 can be connected to the output neutral line 22.

[0042] When installing the electric energy meter body 1, the electric energy meter body 1 is mounted on the bracket 4, and the electric energy meter body 1 is located in the frame 24. The threaded barrel 253 is rotated forward so that the two screw rods 254 are close to each other while the threaded barrel 253 is rotating, so that the two screw rods 254 drive the two clamping plates 256 to approach each other through the two side plates 255 respectively, and make the clamping plates 256 contact with the top of the electric energy meter body 1. Since the top of the clamping plate 256 is inclined, the electric energy meter body 1 can be fixed by means of inclined surface extrusion. When removing the electric energy meter body 1, the threaded barrel 253 is rotated in the opposite direction. Similarly, the two clamping plates 256 are moved away from each other, and the electric energy meter body 1 can be removed.

[0043] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0044] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
