Description

Technical Field

[0001] This invention relates to the field of electricity metering technology, and in particular to a lightweight, modular, integrated busbar-type electricity metering device. Background Technology

[0002] In the field of electricity metering, electricity meters, as the core equipment for measuring users' electricity consumption, need to be replaced regularly to ensure metering accuracy, or upgraded due to equipment aging, functional upgrades, or other requirements. Traditional electricity meter replacement methods have significant technical drawbacks:

[0003] First, traditional meter replacement work requires interrupting the user's power supply, i.e., cutting off the power by disconnecting the incoming switch in the meter box or disconnecting the wires, and restoring power after the meter replacement is completed. This process results in a complete power outage for the user during the meter replacement, which not only affects the normal life of residents (such as air conditioners shutting down, refrigerator insulation failing, and home medical equipment malfunctioning), but also causes economic losses such as production stoppages, data loss, or equipment damage to enterprises that rely on continuous power supply (such as precision manufacturing workshops, data centers, and medical units). The negative impact of power outages during meter replacement is particularly prominent in places with extremely high requirements for power continuity.

[0004] Chinese Patent Publication No. CN220753949U discloses a single-phase uninterruptible power meter replacement connector, including a base, a terminal block, multiple terminals, and a shorting pin assembly. The shorting pin assembly includes a pin holder rotatably mounted on the base, multiple pins, and a shorting conductive plate. One end of each terminal has a contact portion that mates with the pins. One end of each pin moves with the pin holder and can respectively abut against the contact portion of the multiple terminals, enabling connection or disconnection between the terminals and pins. The shorting conductive plate moves with the pin holder and can abut against the contact portion of two adjacent terminals, enabling connection or disconnection between the shorting conductive plate and two adjacent terminals. This connector has the advantages of simple structure, stable and reliable performance, convenient use, high safety, and high meter replacement efficiency.

[0005] Although the aforementioned patent enables uninterrupted meter replacement, the shorting conductive plate is located at the bottom of the pin socket, making it inconvenient for later maintenance. Furthermore, excessive rotation during meter replacement can easily deform the shorting conductive plate, preventing reliable shorting after it has been rotated into place.

[0006] Therefore, it is necessary to invent a lightweight, modular, integrated busbar-type power metering device to solve the above problems. Summary of the Invention

[0022] The pressure plate is placed on top of the push rod and is slidably connected to the sliding seat;

[0025] As a preferred technical solution of the present invention, each group of conductive posts includes two live wire conductive posts and two neutral wire conductive posts, and the live wire conductive posts and neutral wire conductive posts are staggered.

[0026] As a preferred technical solution of the present invention, the mounting base is provided with a flip cover that slides and rotates over the moving contact joint and the stationary contact joint.

[0051] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] This invention provides, for example Figures 1 to 15 The lightweight, modular, integrated busbar-type power metering device shown includes a fixed module 1 and an integrated busbar copper busbar module 2 built into the fixed module 1. In this invention, the fixed module 1 can be made of a high-strength plastic shell, and its interior has an installation cavity adapted to the integrated busbar copper busbar module 2. The fixed module 1 is fixed in the electrical box by bolts or clips to ensure structural stability. It also includes an installation module 3 connected to the integrated busbar copper busbar module 2 and a metering module 4 plugged into the installation module 3. The metering module 4 of this invention is an power meter.

[0053] The integrated busbar copper busbar module 2 includes an integrated busbar copper busbar 21 and multiple sets of conductive posts 22 fixed to the integrated busbar copper busbar 21 by a riveting and expansion method. In this invention, the integrated busbar copper busbar 21 is made of high-purity copper material, which has good conductivity. The surface of the copper busbar is first treated with matte electroplating, and then treated with a powder dipping process. This way, a layer of insulating epoxy resin will be adsorbed on the surface. The riveting and expansion method is to use special equipment to squeeze and deform the connection between the conductive posts 22 and the integrated busbar copper busbar 21, so that the two are tightly combined. The number of sets of conductive posts 22 is determined according to the number of phases of the power metering module 4.

[0054] The mounting module 3 includes a mounting base 31, and a positioning groove 32 is provided on the top of the mounting base 31. In this invention, the mounting base 31 is made of insulating material, and the shape of the positioning groove 32 is adapted to the bottom end of the stationary contact connector 35, which is used to accurately position the stationary contact connector 35 and prevent it from shifting.

[0055] The sliding seat 33 is slidably connected to the top of the mounting base 31, and has a slot 34 thereon. In this invention, the sliding seat 33 and the top of the mounting base 31 are slidably engaged, such as... Figure 6 As shown, the sliding seat 33 can slide along the length of the mounting base 31, and the slot 34 is used to insert the stationary contact connector 35. Specifically, the bottom of the sliding seat 33 is provided with a sliding mating groove 333, and the top of the mounting base 31 is provided with a sliding mating block 334 that mates with the sliding mating groove 333.

[0056] Multiple stationary contact connectors 35, one end of which is inserted into the slot 34 and the other end is inserted into the positioning slot 32, and a storage slot 36 is provided on them.

[0057] Multiple auxiliary docking components 37 are placed inside the storage slot 36 and are detachably snapped into the conductive post 22. They can realize the electrical connection between the conductive post 22 and the stationary contact connector 35, realize the automatic short circuit between conductive posts 22 of the same polarity, and realize the power disconnection between the conductive post 22 and the stationary contact connector 35 at high temperature. In this invention, the snap-fit ​​between the auxiliary docking components 37 and the conductive post 22 facilitates the disassembly and maintenance of the auxiliary docking components 37.

[0058] The pin rotator 38 is rotatably connected to the mounting base 31. Its side wall has an arc-shaped groove 310 that cooperates with the auxiliary docking component 37. It can separate the stationary contact connector 35 from the moving contact connector 39, and can also cooperate with the auxiliary docking component 37 to short-circuit the conductive post 22. In this invention, the pin rotator 38 and the mounting base 31 are rotatably connected by a pin, and the rotation process is smooth.

[0059] Multiple moving contact connectors 39 are connected to the pin header 38 and electrically connected to the stationary contact connector 35. In this invention, the moving contact connectors 39 are connected to the pin header 38, and the number of moving contact connectors 39 corresponds to the number of stationary contact connectors 35.

[0060] The auxiliary docking assembly 37 includes a first conductive cylinder 371 located at the top of the receiving groove 36, which is electrically connected to the stationary contact connector 35.

[0061] The insulating cylinder 372 is threadedly connected to the bottom of the first conductive cylinder 371. In this invention, the threaded connection of the insulating cylinder 372 facilitates installation and disassembly.

[0062] The docking post 373 slides through the mounting base 31 and is inserted into the conductive post 22. It has a groove 374 on its top and an equally divided groove 375 on its bottom. In this invention, the docking post 373 is made of conductive material. The groove 374 is used to accommodate the conductive component 376. The equally divided groove 375 divides the bottom of the docking post 373 into multiple equally divided elastic pieces, which facilitates the engagement with the conductive post 22.

[0063] The conductive component 376 is placed on top of the sink 374. In this invention, the conductive component 376 is made of high-purity copper and its surface is polished to reduce contact resistance. Its shape is adapted to the sink 374 to ensure stable placement.

[0064] The elastic temperature sensing element 377 has one end connected to the conductive element 376 and the bottom of the other end connected to one of the equally spaced elastic sheets of the docking post 373. In this invention, the elastic temperature sensing element 377 is a temperature-sensing bimetallic spring that will deform when the temperature changes.

[0065] The push rod 378 is snapped onto the top of the conductive element 376. This snapping method is achieved by the second elastic arc plate 3764 on the top of the conductive element 376 engaging with the slot on the push rod 378.

[0066] The pressure plate 379 is placed on top of the push rod 378 and is slidably connected to the sliding seat 33. In this invention, the pressure plate 379 is made of insulating material and cooperates with the sliding groove 331 of the sliding seat 33. It can slide in the vertical direction and push the push rod 378 to move.

[0067] Two symmetrically distributed pressure shafts 3710 have one end passing through a sliding seat 33 and detachably connected to a pressure plate 379. The sliding seat 33 has a sliding groove 3711 that mates with the pressure shaft 3710, and the other end is located in an arc-shaped groove 310. In this invention, the pressure shaft 3710 and the pressure plate 379 are detachably connected by bolts, which facilitates replacement and maintenance. The sliding groove 3711 guides the movement of the pressure shaft 3710, ensuring that it moves along a predetermined trajectory.

[0068] The short-circuit conductive piece 3712 is sleeved on the upper part of the push rod 378 and connected to the top of the push rod 378 through an elastic element. Two short-circuit conductive pieces 3712 of the same polarity are electrically connected through a conductive mating part 3713. In this invention, the short-circuit conductive piece 3712 is made of copper sheet, the elastic element is a non-metallic spring, and the conductive mating part 3713 is a conductive metal sheet, ensuring a reliable short circuit between the conductive posts 22 of the same polarity.

[0069] Each set of conductive posts 22 includes two live wire conductive posts 221 and two neutral wire conductive posts 222. The live wire conductive posts 221 and the neutral wire conductive posts 222 are staggered. In this invention, both the live wire conductive posts 221 and the neutral wire conductive posts 222 are made of copper. The staggered distribution can avoid short circuits between the live wire and the neutral wire, thus improving the safety of the device.

[0070] A flip cover 311 is provided on the mounting base 31, which slides and rotates over the moving contact connector 39 and the stationary contact connector 35.

[0071] The stationary contact connector 35 is L-shaped, and the storage groove 36 is located in the vertical section. In this invention, the L-shaped stationary contact connector 35 facilitates electrical connection in both horizontal and vertical directions, and has a compact structure. The storage groove 36 located in the vertical section allows for more reasonable installation of the auxiliary docking assembly 37, saving space.

[0072] The sliding seat 33 has a groove 331 on its top. The inner wall of the groove 331 has a limiting protrusion 332 that cooperates with the pressure plate 379. In this invention, the groove 331 has a rectangular cross-sectional shape and the limiting protrusion 332 is an elastic protrusion. The limiting protrusion 332 can limit the top of the pressure plate 379 when the pressure plate 379 is installed, thereby facilitating the installation of the pressure shaft 3710.

[0073] The bottom of the conductive component 376 is provided with a lower groove 3761 and equally divided through slots, dividing the bottom of the conductive component 376 into multiple first elastic arc plates 3762. In this invention, the lower groove 3761 can make the first elastic arc plates 3762 have better elasticity. The number of equally divided through slots is set as needed, generally 4-6. When the first elastic arc plates 3762 come into contact with the conductive post 22, they can produce elastic deformation to ensure tight contact and form a reliable electrical connection.

[0074] The conductive component 376 has an upper groove 3763 at the bottom and an equally divided through groove at the top, dividing the top part of the conductive component 376 into multiple second elastic arc plates 3764. The inner wall of the second elastic arc plate 3764 has a slot that cooperates with the push rod 378. In this invention, the upper groove 3763 can enhance the elasticity of the second elastic arc plate 3764. The number of equally divided through grooves is the same as that of the first elastic arc plate 3762. The slot and the push rod 378 are firmly engaged and can drive the push rod 378 to move as the conductive component 376 moves.

[0075] When the metering module 4 needs to be replaced, the flip cover 311 is opened, and then the metering module 4 is rotated. The rotation of the metering module 4 will drive the moving contact connector 39 to rotate, which in turn will drive the pin holder 38 to rotate. The rotation of the pin holder 38, under the action of the arc groove 310 and the sliding groove 331, will cause the arc groove 310 to press the pressure shaft 3710 downward. The downward sliding of the pressure shaft 3710 will drive the pressure plate 379 to slide downward. The downward sliding of the pressure plate 379 will drive the push rod 378 to slide downward, causing the push rod 378 to slide downward. The downward sliding of the push rod 378 will, on the one hand, drive the elastic element and the shorting conductive piece 3712 to slide downward, and on the other hand, push the conductive element 376 to slide downward. As the metering module 4 continues to rotate, the shorting conductive piece 3712 will first come into contact with the conductive post 22 to achieve shorting, and then, with continued rotation, the moving contact connector 39 will... Separated from the stationary contact connector 35, the moving contact connector 39 is rotated. The rotation of the moving contact connector 39 will drive the pin holder 38 to rotate. The rotation of the pin holder 38 will cause the arc groove 310 to rotate synchronously. During the rotation of the arc groove 310, the pressure shaft 3710 is pressed downward. After being pressed, the pressure shaft 3710 moves downward and drives the pressure plate 379 to slide downward along the slide groove 331. The downward sliding of the pressure plate 379 pushes the push rod 378 to move downward. The downward movement of the push rod 378 drives the conductive element 376 to slide downward in the sink 374. The downward sliding of the conductive element 376 first makes the first elastic arc plate 3762 contact the conductive post 22 to achieve short circuit. With continued rotation, the pin holder 38 drives the moving contact connector 39 to rotate, and finally the moving contact connector 39 is separated from the stationary contact connector 35, thereby realizing the meter replacement without power interruption and without the moving contact connector 39 being energized.

[0076] When the connection between the metering module 4 and the installation module 3 is not secure, or the circuit load is too large, the temperature between the metering module 4 and the installation module 3 will rise. When the temperature rises to the preset value, the elastic temperature sensing element 377 will deform due to the temperature change, pulling the conductive part 376 downward. The pulling force generated by the deformation of the elastic temperature sensing element 377 pulls the conductive part 376 downward in the sink 374. The conductive part 376 slides downward, first making the first elastic arc plate 3762 contact the conductive post 22 to achieve short circuit. As the temperature continues to rise, the deformation of the elastic temperature sensing element 377 continues to increase, pulling the conductive part 376 to continue sliding downward, causing the conductive part 376 to separate from the push rod 378. The conductive part 376 continues to slide downward under the pull of the elastic temperature sensing element 377, causing the conductive part 376 to be misaligned with the stationary contact joint 35 and no longer in contact, thereby realizing automatic power-off at high temperature, avoiding damage to the metering module 4 due to high temperature, and thus protecting the metering module 4.

[0077] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
