Description

Technical Field

[0001] This invention relates to the field of electricity meter replacement technology, and in particular to a connector structure for replacing electricity meters without power interruption. Background Technology

[0002] The connector used for uninterrupted meter replacement, technically known as a "bypass junction box" or "uninterrupted power supply work junction box," is a crucial electrical safety tool. It is a pre-installed wiring device with special plugs and switches, mainly consisting of a main line interface, a meter interface, a bypass interface, and a switching switch (or pluggable connector). When installing a new meter, the electrician will first connect this junction box in series between the user's meter and the power grid line. Normally, it functions like an ordinary connection point, not affecting normal electricity use or metering.

[0003] Most current meter replacement connectors on the market utilize two sets of L-shaped conductive plug structures in conjunction with the rotation of a pivot point to replace old meters without power interruption. However, in actual operation, these connectors have several drawbacks. First, the timing of meter replacement and the location of the plugs are not fixed, requiring a certain level of operator skill. Second, when removing the old meter, the operator needs to directly contact the meter with their hands. Since the replacement of old meters often involves faults such as leakage and short circuits, direct contact with hands poses a safety hazard, and safety needs to be improved. Summary of the Invention

[0004] This invention discloses a connector structure for uninterrupted meter replacement, aiming to solve the technical problem that most existing plug-in components for uninterrupted meter replacement on the market have shortcomings in terms of ease of operation and safety during actual use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution.

[0006] A connector structure for uninterrupted meter replacement includes a base on which a meter is mounted. A conductive plug is fixed to the bottom of the meter by screws. The base contains a replacement mechanism for uninterrupted meter replacement. The replacement mechanism includes a rotating shaft rotatably mounted inside the base. Several sets of evenly distributed conductive plugs are fixedly mounted on the outside of the rotating shaft. The conductive plug is inserted into the conductive plugs. A sliding cover is slidably mounted on the surface of the base.

[0007] The top of the replacement mechanism is provided with an auxiliary mechanism for disassembling the meter without contact. The auxiliary mechanism includes pressure rods rotatably mounted on both sides of the sliding cover surface. The two pressure rods are slidably connected to a pressing plate through a sliding groove. The pressing plate presses against the outside of the meter.

[0008] The bottom of the base is provided with a conductive component that supplies power to the meter.

[0009] By utilizing the auxiliary mechanism in conjunction with the one-way rotation of the replacement mechanism, the electricity meter can be replaced without contact or interruption of power.

[0010] By incorporating a replacement mechanism into the traditional connector structure used for uninterrupted meter replacement, the traditional L-shaped multi-directional rotating conductive plug structure is transformed into an X-shaped unidirectional rotating conductive plug structure. With a single operation, the operator rotates the old meter, creating space for the new meter to be plugged in. This process is repeated for each operation, significantly reducing the operator's skill requirements and improving the ease of use of traditional components. Furthermore, an auxiliary mechanism is located at the top of the replacement mechanism. Once the rotated old meter reaches the top of this auxiliary mechanism, the operator can use it to remove the old meter without contact, thus greatly improving the safety of meter replacement using traditional connectors.

[0011] In a preferred embodiment, a straight plate is fixedly installed at the end of the sliding cover, and both the end of the rotating shaft and the straight plate extend into the interior of the base. A set of gears is meshed between the end of the rotating shaft and the inner wall of the base. A one-way ratchet is fixedly installed on the outer side of a single gear in the gear set. A set of elastic protruding teeth is slidably installed on the top of the straight plate, and the one-way ratchet and the elastic protruding teeth are meshed together.

[0012] By incorporating a replacement mechanism into the traditional connector structure used for uninterrupted meter replacement, the traditional L-shaped multi-directional rotating conductive plug structure is transformed into an X-shaped unidirectional rotating conductive plug structure. Each unidirectional movement of the sliding cover drives a gear set connected to the rotating shaft via a unidirectional drive structure consisting of elastic teeth and a unidirectional ratchet. This rotation, in turn, causes the X-shaped conductive plug to rotate unidirectionally, simultaneously changing the orientation of the old meter and creating space for the new meter to be plugged in. This process is repeated for each operation, significantly reducing the operator's skill level required for the components and improving the ease of use of traditional components.

[0013] In a preferred embodiment, a clamping plate is rotatably mounted on each of the inner sides of the extrusion plate, and the clamping plate and the pressure rod are pressed into contact and clamped to both sides of the meter.

[0014] By further providing an auxiliary mechanism on the top of the sliding cover, when the old meter that has changed direction reaches the top of the auxiliary mechanism, the worker can press the pressure rod by hand, causing the end of the pressure rod to move along the inside of the slide groove and lift the extrusion plate. The extrusion plate extrudes the meter, causing the meter to be disconnected from the power-on state. At the same time, the clamping plate that is simultaneously compressed can fix the disconnected old meter. Thus, the old meter can be disassembled without contact using the auxiliary mechanism, which greatly improves the safety of replacing meters when using traditional plug-in components.

[0015] In a preferred embodiment, the conductive component includes a wiring cavity formed at the end of the base, a plurality of wires are connected inside the wiring cavity, and an insulating plate is fixedly installed inside the wiring cavity by screws. The insulating plate covers the outside of the wires, and the base has a built-in conductive wire. The circuit between the wires and the rotating shaft is conducted through the conductive wire connected to the screws on the outside of the insulating plate.

[0016] By setting a wiring cavity structure at the bottom of the base, and using the wiring cavity in conjunction with the insulating plate fixed by screws, the wires introduced into the base are fixed. The conductor wires built into the base can conduct the circuit between the wires and the rotating shaft through the screws on the outside of the insulating plate, thereby maintaining the normal power supply and operation of the meter.

[0017] As can be seen from the above, the connector structure for uninterrupted meter replacement provided by the present invention has the following technical effects.

[0018] Firstly, by improving the traditional L-shaped multi-directional rotating conductive plug structure for uninterrupted meter replacement, the traditional L-shaped multi-directional rotating conductive plug structure is transformed into an X-shaped unidirectional rotating conductive plug structure. The movement of the sliding cover controls the rotation of the unidirectional ratchet, which in turn drives the X-shaped conductive plug to rotate unidirectionally. Simultaneously, the old meter is rotated, making room for the new meter to be plugged in. This process is repeated for each operation, and workers only need to disassemble and assemble the meter according to specific positions. This significantly reduces the skill requirements of the operators for the components and improves the convenience of using traditional components.

[0019] Secondly, by further setting an auxiliary mechanism on the top of the sliding cover, when the old meter that has changed direction reaches the top of the auxiliary mechanism, the worker can press the pressure rod by hand, causing the end of the pressure rod to move along the inside of the slide groove and lift the extrusion plate. The extrusion plate is used to extrude the meter, causing the meter to be disconnected from the power supply. At the same time, the clamping plate that is simultaneously extruded can fix the old meter that has been disconnected, preventing the old meter from falling. Thus, the old meter can be disassembled without contact using the auxiliary mechanism, which greatly improves the safety of replacing meters using traditional plug-in components.

[0020] Thirdly, the sliding cover is fixed with screws, which prevents the new meter from being flipped. Combined with the telescopic clips and slots, the new meter cannot be disassembled, ensuring stability after installation. Attached Figure Description

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0035] The connector structure for uninterrupted meter replacement disclosed in this invention is mainly used in scenarios where meters need to be replaced without interrupting power.

[0036] Reference Figures 1 to 12 A connector structure for replacing an electricity meter without power interruption includes a base 2, on which an electricity meter is mounted. A conductive plug plate 6 is fixed to the bottom of the electricity meter by screws. The base 2 is equipped with a replacement mechanism 3 for replacing the electricity meter without power interruption. The replacement mechanism 3 includes a rotating shaft 301 rotatably mounted inside the base 2. Several sets of evenly distributed conductive plugs 302 are fixedly mounted on the outside of the rotating shaft 301. The conductive plug plate 6 is inserted into the interior of the conductive plugs 302. A sliding cover 303 is slidably mounted on the surface of the base 2.

[0037] The top of the replacement mechanism 3 is provided with an auxiliary mechanism 4 for disassembling the meter without contact. The auxiliary mechanism 4 includes pressure rods 401 rotatably mounted on both sides of the surface of the sliding cover 303. The two pressure rods 401 are slidably connected to a pressing plate 403 through a sliding groove 402. The pressing plate 403 presses against the outside of the meter.

[0038] The bottom of the base 2 is provided with a conductive component 5 that supplies power to the meter.

[0039] By using the auxiliary mechanism 4 in conjunction with the one-way rotation of the replacement mechanism 3, the electricity meter can be replaced without contact or interruption of power.

[0040] In this embodiment: Under normal conditions, the base 2 is energized via the conductive component 5. Simultaneously, a meter is connected to the replacement mechanism 3 inside the base 2 via a conductive insert 6. When a worker needs to replace the meter, the worker manually rotates the replacement mechanism 3, causing the old meter connected to the base 2 to rotate. At the same time, the worker holds a new meter and inserts it into the initial position of the old meter. The specific operating state is as follows: Figure 3 As shown, during this process, the old electricity meter that is rotating will move to the top of the auxiliary mechanism 4. At this time, the worker presses the auxiliary mechanism 4 with his hand, causing the auxiliary mechanism 4 to be squeezed outward, so that the conductive plug 6 at the bottom of the old electricity meter is disconnected from the connection state of the replacement mechanism 3. At the same time, the old electricity meter that has fallen off is clamped, and the replacement of the electricity meter is completed without interrupting the power supply.

[0041] Reference Figures 1 to 9 In a preferred embodiment, a straight plate 304 is fixedly installed at the end of the sliding cover 303. The end of the rotating shaft 301 and the straight plate 304 both penetrate into the interior of the base 2. A set of gears 305 is meshed between the end of the rotating shaft 301 and the inner wall of the base 2. A one-way ratchet 306 is fixedly installed on the outer side of a single gear in the gear set 305. A set of elastic teeth 307 is slidably installed on the top of the straight plate 304. The one-way ratchet 306 and the elastic teeth 307 are meshed together.

[0042] Under normal conditions, the base 2 is energized via the conductive component 5. Simultaneously, a meter is connected to a set of conductive plugs 302 inside the base 2 via conductive plates 6. When a worker needs to replace the meter, they manually move the sliding cover 303 towards the conductive component 5. The moving cover 303, through the straight plate 304 and the elastic teeth 307, pulls a one-way ratchet 306. The rotating ratchet 306 drives the meshing gear set 305 to rotate. The rotating gear set 305 drives the rotating shaft 301 and several sets of conductive plugs 302 to rotate synchronously, causing the old meter connected inside the base 2 to rotate. Simultaneously, the worker holds a new meter and inserts the conductive plate 6 at the bottom of the new meter into the conductive plug 302 at the initial position of the old meter. The specific operating state is as follows: Figure 3 As shown, after the installation of the new meter is completed, the worker reverses the sliding cover 303 to reset it. The moved sliding cover 303 cannot pull the one-way ratchet 306 to rotate through the elastic tooth 307. In this state, the elastic tooth 307 will retract downwards, and the one-way ratchet 306 and the elastic tooth 307 cannot transmit power.

[0043] Specifically, the end of the base 2 is provided with a telescopic clip 1, and the back of the meter is provided with a slot 7. When the worker installs the new meter, he first presses the back of the new meter against the outside of the telescopic clip 1 and slides it horizontally. The pressed telescopic clip 1 moves toward the inside of the base 2. As the worker slides the meter, the telescopic clip 1, which moves relative to the meter, slides and engages with the inside of the slot 7, thereby fixing the new meter.

[0044] Specifically, the elastic protrusion 307 is connected to the straight plate 304 via a spring and can slide up and down along the inside of the straight plate 304.

[0045] Furthermore, a protective cover 308 is fixedly installed on the top of the base 2. The protective cover 308 is distributed on the outside of the conductive plug 302, thereby further improving the shielding effect on the outside of the conductive plug 302 and reducing the area of ​​accidental contact.

[0046] Reference Figures 1 to 2 , Figures 4 to 5 , Figures 8 to 9 In a preferred embodiment, a clamping plate 404 is rotatably mounted on each of the inner sides of the extrusion plate 403. The clamping plate 404 and the pressure rod 401 are pressed into contact and clamped on both sides of the meter.

[0047] The rotating old electricity meter moves to the top of the pressing plate 403. Since meter replacement often occurs when an old meter needs to be replaced, and the aging of the old meter's wiring may cause insulation damage, potentially leading to leakage in the meter casing, the worker presses down on the pressure rod 401 by hand to make it rotate. The upper end of the rotating pressure rod 401 slides along the inside of the slide groove 402 and pushes the pressing plate 403, causing the pressing plate 403 to move upward and squeeze the old electricity meter. At the bottom, the conductive plug 6 at the bottom of the old meter is disconnected from the conductive plug 302. As the pressure rod 401 rotates, it also squeezes the clamping plate 404, causing the clamping plate 404 to rotate synchronously and clamp the detached old meter, preventing it from falling. Then, the old meter can be picked up by hand, thus completing the meter replacement without interrupting the power supply and ensuring the safety of disassembly and assembly. The advantages of replacing the meter without interrupting the power supply are: no need to replace the meter without power interruption, higher replacement efficiency, and reduced economic losses caused by power outages.

[0048] Each pressure bar 401 has an extension plate 405 fixed to the outer side of its extrusion end. The extension plate 405 increases the extrusion stroke of the pressure bar 401, causing the pressure bar 401 to press against the clamping plate 404.

[0049] Specifically, the clamping plate 404 has a "Z" shaped cross section, and the pressing plate 403 has an "L" shaped cross section. The two are rotatably connected, and the end of the clamping plate 404 near the extension plate 405 is inclined, so that the extension plate 405 can press the clamping plate 404 to rotate. The pressure rod 401, the pressing plate 403, the extension plate 405 and the clamping plate 404 are all made of non-conductive materials, realizing contactless disassembly of old meters.

[0050] Furthermore, a return spring 406 is fixedly connected between the rotating end of each pressure rod 401 and the sliding cover 303. After the worker releases the pressure contact of the pressure rod 401, the pressure rod 401, which is no longer restricted by pressure, will be pushed by the return spring 406, thereby generating a return rotation. The return rotation of the pressure rod 401 will also drive the pressure plate 403 to return to its original position.

[0051] Reference Figures 1 to 5 , Figures 8 to 9 In a preferred embodiment, the conductive component 5 includes a wiring cavity 501 opened at the end of the base 2. A plurality of wires 502 are connected inside the wiring cavity 501. An insulating plate 503 is fixedly installed inside the wiring cavity 501 by screws. The insulating plate 503 covers the outside of the wires 502. The base 2 has a built-in conductive wire. The conductive wire is connected to the screws on the outside of the insulating plate 503 to conduct the circuit between the wires 502 and the rotating shaft 301. A flip cover 504 is rotatably installed on the side of the sliding cover 303. The flip cover 504 covers the outside of the insulating plate 503 and is fixed to the base 2 by screws.

[0052] Before the worker moves the sliding cover 303, the screws on the side of the flip cover 504 need to be removed with a screwdriver. At this time, the sliding cover 303 is released from its fixed state, and the worker can flip the flip cover 504 upwards (e.g., Figure 2 As shown, the insulating plate 503 is exposed to allow for wiring inspection of the wires 502 inside the wiring cavity 501.

[0053] Working principle: During use, the base 2 is energized through the conductive component 5. Simultaneously, a meter is connected to a set of conductive sockets 302 inside the base 2 via conductive inserts 6. When the meter needs to be replaced, the screws on the side of the flip cover 504 need to be removed with a screwdriver. At this time, the sliding cover 303 is released from its fixed state. Then, the worker manually moves the sliding cover 303 away from the telescopic latch 1. The moved sliding cover 303 pulls the one-way ratchet 306 through the straight plate 304 and the elastic convex tooth 307. The rotating one-way ratchet 306 drives the meshing gear set 305 to rotate. The rotating gear set 305 will... The rotating shaft 301 and several sets of conductive plugs 302 rotate synchronously, causing the old meter plugged into the base 2 to rotate. Simultaneously, a worker holds a new meter and inserts the conductive plug 6 at the bottom of the new meter into the conductive plug 302 at the initial position of the old meter. During insertion, the back of the new meter needs to be pressed against the outside of the telescopic locking piece 1 and slid horizontally. The pressed telescopic locking piece 1 moves inward towards the base 2. As the worker slides the meter, the relatively moved telescopic locking piece 1 slides and engages with the slot 7, thus limiting the vertical position of the new meter. The specific operating state is as follows: Figure 3 As shown.

[0054] The old electricity meter that has been rotated will move to the top of the pressing plate 403. At this time, the worker presses down on the lower end of the pressing rod 401 by hand (e.g., Figure 8 and Figure 11 As indicated by the arrow in the diagram, the pressure rod 401 rotates. The upper end of the rotating pressure rod 401 slides along the inside of the slide groove 402 and pushes the pressing plate 403, causing the pressing plate 403 to move upward and press the bottom of the old meter. This causes the conductive plug 6 at the bottom of the old meter to gradually detach from the conductive plug 302. At the same time, the pressure rod 401 rotates and presses the clamping plate 404 through the extension plate 405, causing the clamping plate 404 to rotate synchronously and clamp the old meter that is about to be disconnected from the electrical connection. When the pressure rod 401 rotates to its limit position, it means that the conductive plug 6 of the old meter is completely disconnected from the conductive plug 302. At this time, the clamping force of the clamping plate 404 is also the maximum, preventing the old meter from falling. At this time, the personnel can safely remove the old meter. This process can effectively reduce the safety hazards caused by leakage faults of the old meter and can also complete the replacement of the meter without interrupting the power supply.

[0055] After replacing the electricity meter, the worker reverses the sliding cover 303 to reset it, and then fixes the sliding cover 303 again with screws. At this time, the sliding cover 303 can no longer slide, and the new electricity meter after electrical connection cannot be flipped. With the restriction of telescopic clip 1 and slot 7, the new electricity meter cannot be disassembled at this time, ensuring the stability after installation.

[0056] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
