Description

Technical Field

[0001] This invention relates to the field of meter replacement device technology, specifically to an uninterruptible power meter replacement device. Background Technology

[0002] Currently, in the field of electricity metering, plug-in meters are widely used due to their ease of installation and disassembly. To ensure uninterrupted power supply for users during meter replacement, existing technologies employ a short-circuit mechanism that automatically disconnects after the meter is inserted. The core idea is to conduct bypass current through the short-circuit mechanism when the meter is not plugged in, and automatically disconnect the short circuit after the meter is plugged in, thus switching the current to the meter's metering path and avoiding power outages during meter replacement.

[0003] A search revealed that patent CN112415241B discloses a low-voltage uninterrupted meter replacement plug-in base. To achieve rapid uninterrupted meter replacement, it employs a meter plug-in structure, and synchronizes the meter plugging / unplugging action with the short-circuit switch's on / off state. However, this type of synchronized structure has significant drawbacks: there are no mechanical limits during meter installation and removal, allowing operators to forcibly remove the meter; during removal, a time difference can occur where the meter pins detach from the terminal before the short-circuit mechanism reliably closes, creating a power outage gap and causing momentary power loss for the user. Furthermore, direct contact separation under load can easily generate an electric arc at the moment of separation between the pins and conductive components / plates. Long-term use can cause erosion and oxidation of conductive parts, leading to poor contact, abnormal temperature rise, and increased failure rate of the mechanism. In severe cases, it can even damage precision electrical equipment on the user's side and disrupt production. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide an uninterruptible power meter replacement device that, through a forced process, ensures that the meter must be pulled out in a short-circuit state, thereby improving safety.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is: an uninterruptible power meter replacement device, comprising:

[0006] A plug-in base for connecting to an electricity meter;

[0007] The four-wire component is provided on the plug-in base. The wiring component includes interconnected terminals and pins. The pins are used to insert into the electricity meter. The terminals are connected to the plug-in base. The four terminals are connected from left to right to the live wire inlet, live wire outlet, neutral wire inlet, and neutral wire outlet.

[0008] A shorting component includes two shorting assemblies. One shorting assembly is respectively disposed between the two terminals on the left and between the two terminals on the right. Each shorting assembly includes a conductive plate electrically connected to the corresponding terminal and a conductive element that cooperates with the conductive plate and is vertically slidably disposed on the plug-in base. A connector is connected between the two conductive elements of the shorting assembly. The conductive element is adapted to be moved to contact or disconnect from the corresponding conductive plate.

[0009] A movable component includes a movable member that is vertically slidably disposed on the plug-in base. The movable member is provided with an insulating plate for connecting all the conductive members. The movable member has an upper position and a lower position during vertical sliding. When the movable member is in the lower position, the conductive members are in contact with the conductive plate. When the movable member is in the upper position, the conductive members are not in contact with the conductive plate.

[0010] The second limiting component includes a positioning member that is vertically slidably disposed on the plug-in base and a second limiting member that is horizontally slidably disposed on the plug-in base;

[0011] The docking assembly, after the meter's pins are inserted into position, connects the meter to the positioning component via the docking assembly, and pushes the positioning component to slide vertically to the locked position; wherein,

[0012] When the electricity meter is connected to the plug-in base, the moving part is moved to the upper position, the moving part contacts the second limiting part and pushes the second limiting part to move horizontally, the second limiting part moves horizontally to the positioning part in the insertion locking position to restrict the vertical movement of the positioning part, thereby restricting the electricity meter from being pulled out.

[0013] Furthermore, the positioning member has a second limiting groove that extends through itself. The second limiting groove includes a positioning surface. When the second limiting member is pushed to move toward the positioning member, part of the second limiting member extends into the second limiting groove, and part of the lower surface of the second limiting member abuts against the positioning surface, thereby limiting the positioning member through the second limiting member.

[0014] Furthermore, the movable member is provided with a second pushing part, and the second limiting member is provided with a second force receiving part that cooperates with the second pushing part at one end near the movable member. When the movable member is moved upward, the second pushing part abuts against the second force receiving part and squeezes the second force receiving part, thereby pushing the second limiting member toward the positioning member.

[0015] Furthermore, the movable component also includes elastic elements that respectively connect the plug-in base and the movable member;

[0016] When the movable element is in the lower position, the conductive element is in contact with the conductive plate, and the elastic element is in a compressed state;

[0017] When the movable member is in the upper position, the elastic element is in its natural state.

[0018] Furthermore, in order to control the movement of the movable component, a control channel is provided on the plug-in base for connecting the movable component and the external space of the plug-in base. A handle is detachably plugged into the movable component, the handle passes through the control channel, and the handle is adapted to be moved downward, thereby driving the movable component to move down until the conductive component contacts the conductive plate.

[0019] Furthermore, a second elastic component is provided between the positioning component and the plug-in base. The second elastic component is adapted to move and reset the positioning component when the meter is disconnected from the plug-in base.

[0020] A third elastic component is provided between the second limiting member and the insertion base for resetting the second limiting member.

[0021] Furthermore, in order to restrict the movement of the electricity meter, the docking assembly includes a docking part disposed on the electricity meter and a docking mechanism disposed on the positioning part. When the electricity meter is docked with the plug-in base, the docking part and the docking mechanism cooperate to connect the positioning part and the electricity meter.

[0022] The docking mechanism includes two horizontally sliding clamps mounted on the positioning member, and a fourth elastic component is provided between the clamps and the positioning member;

[0023] The docking component is provided with a docking part corresponding to the positioning component, and the positioning component is provided with a docking groove corresponding to the docking part. When the meter docks with the plug-in base, the docking part contacts the clamping plate and pushes the two clamping plates to move back to back, thereby causing the docking part to partially enter the docking groove. When the docking part partially enters the docking groove, the clamping plate moves and resets through the fourth elastic component to clamp the remaining part of the docking part.

[0024] Furthermore, in order to maintain the short-circuit state and automatically disconnect the short-circuit after the meter is replaced, the uninterruptible meter replacement device also includes a first limiting component for limiting the position of the moving part. When the meter is not connected to the plug-in base, the first limiting component restricts the position of the moving part to the lower position, so that the conductive part is in contact with the corresponding conductive plate.

[0025] When the meter is connected to the plug-in base, the first limiting component releases the restriction on the moving part, and the moving part is adapted to be moved to the upper position to disconnect the contact between the conductive part and the conductive plate.

[0026] Furthermore, the first limiting component includes a first limiting member that is horizontally slidably disposed on the plug-in base. The first limiting member is located below the second limiting member. The first limiting member is configured such that when the moving member is moved to the lower position, the first limiting member is in the initial position and inserted into the moving member, thereby restricting the moving member to the lower position. When the meter docks with the plug-in base, the positioning member is pushed down by the meter, thereby contacting the first limiting member and pushing the first limiting member to move horizontally until it disengages from the moving member. After the moving member is unrestricted, it is moved to the upper position to disconnect the contact between the conductive member and the conductive plate.

[0027] A first elastic component for resetting the first limiting member is provided between the first limiting member and the insertion base.

[0028] Furthermore, to prevent accidental power outages when the meter is not fully inserted, a delay mechanism is provided between the insulating plate and the conductive component. When the moving component moves to the upper position, the delay mechanism causes the insulating plate to move a short distance before pushing the conductive component to move until it breaks contact with the conductive plate.

[0029] The delay mechanism includes an outer sleeve connected to the conductive element and an inner sleeve vertically slidably disposed within the outer sleeve. The inner sleeve is connected to the insulating plate. When the insulating plate is moved upward, the insulating plate causes the inner sleeve to slide within the outer sleeve first, and then pushes the outer sleeve upward.

[0030] By adopting the above technical solution, the present invention has the following beneficial effects:

[0031] During the meter replacement process, the old meter has been removed, and the moving part is held in the lower position, keeping the conductive part in contact with the conductive plate to form a short circuit. Current flows normally without being affected by the removal of the old meter, ensuring uninterrupted power supply to the user. When a new meter needs to be inserted, the new meter and the positioning part are connected via a docking assembly. During the docking process, the new meter moves the positioning part downwards. Once docking is complete, the positioning part is in the locked position. At this point, the moving part is moved and held in the upper position to disconnect the short circuit. Simultaneously, the upward-moving moving part pushes the second limiting part towards the positioning part until it is inserted into the locked position, limiting the positioning part. This prevents the new meter from being removed while the short circuit is disconnected. The moving part must be moved to the lower position to ensure the conductive part and conductive plate are in contact, maintaining a short circuit before the meter can be removed.

[0052] To make the content of this invention easier to understand, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0053] Example 1: As Figure 1-5 , Figure 8-9 As shown, an uninterruptible power meter replacement device includes:

[0054] Plug base 1 for connecting to the electricity meter;

[0055] A four-wire component is provided on the plug-in base 1. The wiring component includes interconnected terminals 11 and pins 12. The pins 12 are used to insert the meter. The terminals 11 are connected to the plug-in base 1. The four terminals 11 are connected from left to right to the live wire inlet, live wire outlet, neutral wire inlet and neutral wire outlet.

[0056] The shorting component includes two shorting assemblies. A shorting assembly is respectively provided between the two terminals on the left and between the two terminals on the right. The shorting assembly includes a conductive plate 2 electrically connected to the corresponding terminal 11 and a conductive element 21 that cooperates with the conductive plate 2 and is vertically slidably disposed on the plug-in base 1. A connector 22 is connected between the two conductive elements 21 of the shorting assembly. The conductive element 21 is adapted to be moved to contact or disconnect from the corresponding conductive plate 2.

[0057] The movable component includes a movable part 3 that is vertically slidably disposed on the plug-in base 1. The movable part 3 is provided with an insulating plate 31 for connecting all conductive parts 21. The movable part 3 has an upper position and a lower position during vertical sliding. When the movable part 3 is in the lower position, the conductive parts 21 are in contact with the conductive plate 2. When the movable part 3 is in the upper position, the conductive parts 21 are not in contact with the conductive plate 2.

[0058] The second limiting component includes a positioning member 42 that is vertically slidably disposed on the plug-in base 1 and a second limiting member 7 that is horizontally slidably disposed on the plug-in base 1.

[0059] The docking assembly connects the meter to the positioning component 42 after the meter is inserted into the pin 12, and pushes the positioning component 42 to slide vertically to the locked position.

[0060] When the meter is connected to the plug-in base 1, the moving part 3 is moved to the upper position. The moving part 3 contacts the second limiting part 7 and pushes the second limiting part 7 to move horizontally. The second limiting part 7 moves horizontally to the positioning part 42 in the insertion locking position to restrict the vertical movement of the positioning part 42, thereby restricting the meter from being pulled out.

[0061] Specifically, the meter has a plug that mates with the pin 12. When the meter is fully connected to the base 1, the pin 12 abuts against the plug, allowing current to flow through the pin 12 and then into the meter. The meter is existing technology, and its internal structure and working principle will not be described in detail here.

[0062] Furthermore, when the conductive element 21 contacts the conductive plate 2, it is in a short-circuit state. In the short-circuit state, the live wire inlet and live wire outlet are connected to the circuit through the corresponding connector 22, and the neutral wire inlet and neutral wire outlet are connected to the circuit through the corresponding connector 22. When the conductive element 21 and the conductive plate 2 are disconnected, it is in a short-circuit disconnected state. In this state, after the meter is connected to the plug-in base 1, the current flows through the meter.

[0063] In this embodiment, as Figure 1-5 , Figure 8-9 As shown, all components within the plug-in base 1 are in their initial state. At this time, the old meter being replaced has been removed, and the moving part 3 is held in the lower position, ensuring that the conductive part 21 and the conductive plate 2 remain in contact, forming a short circuit. Current flows normally without being affected by the removal of the old meter, ensuring uninterrupted power supply to the user. When a new meter needs to be inserted, the new meter and the positioning part 42 are connected via a docking assembly. During the docking process between the new meter and the plug-in base 1, the positioning part 42 moves downwards. After docking is complete, the positioning part 42 is in the locked position. At this point, the moving part 3 is moved and held in place. The short circuit is disconnected at the upper position. At the same time, the moving part 3 pushes the second limiting part 7 to the positioning part 42 to be inserted into the positioning part 42 which is in the locked position, thus limiting the positioning part 42. This ensures that the new meter cannot be pulled out when the short circuit is disconnected. The moving part 3 must be moved to the lower position so that the conductive part 21 and the conductive plate 2 are in contact. Only when the short circuit is in the short circuit state can the meter be pulled out. When the short circuit is in the short circuit state, all components are in the initial state, that is, the second limiting part 7 does not limit the positioning part 42, so the meter can be pulled out.

[0064] Specifically, such as Figure 8-9As shown, the positioning member 42 has a second limiting groove 71 that extends through itself. The second limiting groove 71 includes a positioning surface 75. When the second limiting member 7 is pushed to move towards the positioning member 42, part of the second limiting member 7 extends into the second limiting groove 71, and part of the lower surface of the second limiting member 7 abuts against the positioning surface 75. Thus, the positioning member 42 is limited by the second limiting member 7, so that the positioning member 42 cannot move upward.

[0065] Specifically, such as Figure 8-9 As shown, the movable member 3 is provided with a second pushing part 73, and the second limiting member 7 is provided with a second force receiving part 72 that cooperates with the second pushing part 73 at one end near the movable member 3. When the movable member 3 is moved upward, the second pushing part 73 abuts against the second force receiving part 72 and squeezes the second force receiving part 72, thereby pushing the second limiting member 7 toward the positioning member 42.

[0066] Furthermore, both the second pushing part 73 and the second force receiving part 72 can be arranged in an arc shape.

[0067] like Figure 5 As shown, the movable assembly also includes an elastic element 32 that connects the insertion base 1 and the movable part 3 respectively;

[0068] When the moving part 3 is in the lower position, the conductive part 21 is in contact with the conductive plate 2, and the elastic element 32 is in a compressed state.

[0069] When the movable part 3 is in the upper position, the elastic element 32 is in its natural state.

[0070] Specifically, such as Figure 5 As shown, the elastic element 32 can be a spring, with the two ends of the spring connected to the moving part 3 and the insertion base 1, respectively.

[0071] In this embodiment, the old meter is unplugged. In the initial state of the plug-in base 1, the conductive element 21 is in contact with the conductive plate 2. At this time, the movable element 3 is restricted to the lower position and cannot move. In this state, the elastic element 32 is in a compressed state. When the new meter is plugged in, the restriction on the movable element 3 is released, and the movable element 3 can move. At the same time as the restriction is removed, the elastic element 32 returns to its natural state and drives the movable element 3 to move to the upper position.

[0072] like Figure 2 , Figure 5 , Figure 6 As shown, the plug-in base 1 has a control channel for connecting the movable part 3 and the external space of the plug-in base 1. The movable part 3 is detachably plugged with a handle 6. The handle 6 passes through the control channel and is adapted to be moved downward, thereby driving the movable part 3 to move down to contact the conductive part 21 and the conductive plate 2.

[0073] Specifically, such as Figure 6 As shown, the handle 6 includes an annular portion 61 and a locking block 62. The moving part 3 has a locking groove 64 corresponding to the locking block 62, an annular groove 63 corresponding to the annular portion 61, and a closing portion 65 for supporting the locking block 62.

[0074] In this embodiment, when the moving part 3 is in the upper position, the short circuit is disconnected. When a new meter needs to be replaced, the conductive part 21 should be moved to contact the conductive plate 2 first. At this time, the handle 6 is inserted into the moving part 3, and the handle 6 is manually operated to move the moving part 3 to the lower position, so that the conductive part 21 contacts the conductive plate 2. The specific operation method of inserting the handle 6 into the moving part 3 is as follows: align the annular part 61 and the locking block 62 on the handle 6 with the annular groove 63 and the locking groove 64 respectively, and then insert it. After insertion, rotate the handle 6 to move the locking block 62 to the closed part 65. At this time, the lower part... The handle 6 can drive the movable part 3 to move synchronously to the lower position. In the short-circuit state, the old meter is pulled out. By controlling the handle 6, the movable part 3 is kept in the lower position, so that the new meter is always in the short-circuit state before it is inserted. Then the new meter is inserted, and the handle 6 is released, so that the movable part 3 is reset to the upper position through the elastic element 32. After the movable part 3 is reset, the handle 6 is rotated in the opposite direction until the locking block 62 is aligned with the locking slot 64, and the handle 6 is pulled out of the movable part 3. The detachable design of the handle 6 can further increase the difficulty for non-operators to short-circuit and steal electricity.

[0075] like Figure 8-9 As shown, a second elastic component 48 is provided between the positioning component 42 and the plug-in base 1. The second elastic component 48 is adapted to drive the positioning component 42 to move and reset when the meter is disconnected from the plug-in base 1.

[0076] A third elastic component 74 is provided between the second limiting member 7 and the insertion base 1 for resetting the second limiting member 7. Specifically, when the second limiting member 7 is not in contact with the moving member 3, the third elastic component 74 drives the second limiting member 7 to move and reset until it disengages from the positioning member 42.

[0077] Specifically, both the second elastic component 48 and the third elastic component 74 can be springs or a combination of springs and telescopic rods. Taking the second elastic component 48 as an example, the two ends of the telescopic rod are respectively connected to the positioning component 42 and the plug-in base 1. The spring is set outside the telescopic rod, and the two ends of the spring are respectively connected to the positioning component 42 and the plug-in base 1.

[0078] In this embodiment, when the second elastic component 48 is in its natural state, the positioning member 42 extends out of the plug-in base 1. When the meter is connected to the plug-in base 1, the meter pushes the positioning member 42 to move, causing the second elastic component 48 to retract. When the meter is pulled out, the second elastic component 48 resets and drives the positioning member 42 to reset.

[0079] When the third elastic component 74 is in its natural state, the second limiting member 7 is in its initial position, not in contact with the moving member 3 or the positioning member 42. When the second limiting member 7 is pushed by the moving member 3, the third elastic component 74 is compressed. When the moving member 3 is no longer in contact with the second limiting member 7, the third elastic component 74 resets and drives the second limiting member 7 to reset.

[0080] like Figure 1 , Figure 8-12 As shown, the docking assembly includes a docking part 8 disposed on the meter and a docking mechanism 81 disposed on the positioning part 42. When the meter is docked with the plug-in base 1, the docking part 8 and the docking mechanism 81 cooperate to connect the positioning part 42 and the meter.

[0081] The docking mechanism 81 includes two horizontally sliding clamps 82 mounted on the positioning member 42, and a fourth elastic component 83 is provided between the clamps 82 and the positioning member 42.

[0082] The docking part 8 is provided with a docking part 84 corresponding to the positioning part 42. The positioning part 42 is provided with a docking groove 85 corresponding to the docking part 84. When the meter is docked with the plug-in base 1, the docking part 84 contacts the clamping plate 82 and pushes the two clamping plates 82 to move back to back, thereby causing part of the docking part 84 to enter the docking groove 85. When part of the docking part 84 enters the docking groove 85, the clamping plate 82 moves and resets through the fourth elastic component 83 to clamp the remaining part of the docking part 84.

[0083] Specifically, such as Figure 12 As shown, the docking part 84 includes a ball 86 that mates with the docking groove 85 and a handle 87 for connecting the ball 86 and the docking piece 8. Inclined parts 88 that mate with the ball 86 are provided on both the upper and lower surfaces of the clamping plate 82.

[0084] In this embodiment, the docking component 8 is first connected to the electricity meter. Then, the electricity meter is docked with the plug-in base 1. The electricity meter and docking component 8 move downwards synchronously. Before the electricity meter is fully plugged in, the ball 86 first contacts the inclined portion 88 above the clamping plate 82. As the electricity meter continues to move downwards, the ball 86 pushes the two clamping plates 82 to move back to back, thereby opening the docking groove 85 and allowing the ball 86 to enter the docking groove 85. When the ball 86 is fully inside the docking groove 85, the two clamping plates 82 lose the support of the ball 86 and are reset by the fourth elastic component 83, clamping the handle 87 and simultaneously closing the docking groove 85. At this point, the docking of the docking component 8 and the positioning component 42 is completed, i.e., the electricity meter and the positioning component 42 are docked. When the electricity meter is fully plugged in, the positioning component 42 and the clamping plate 82 are fully inserted into the plug-in base 1, and the clamping plate 82 and the plug-in base... When the inner walls of the insertion base 1 are abutted and the positioning member 42 is in the locked position, the positioning member 42 is inserted and limited by the second limiting member 7. The positioning member 42 and the clamping plate 82 cannot move upward. Due to the restriction of the inner wall of the insertion base 1, the two clamping plates 82 cannot move back to back to open the docking groove 85, so that the meter and the positioning member 42 cannot move upward. Thus, when the meter is pulled out, it must first be in a short-circuit state. When it is in a short-circuit state, the second limiting member 7 does not restrict the positioning member 42. The positioning member 42 can move upward to pull out the meter. When the positioning member 42 moves upward to the point that the clamping plate 82 is no longer restricted by the inner wall of the insertion base 1, as the meter continues to move upward, the ball 86 contacts the inclined part 88 below and pushes the two clamping plates 82 to move back to back again, finally causing the ball 86 to leave the docking groove 85 and completing the removal of the meter.

[0085] It should be noted that the connecting piece 8 can be fixed to the outer casing of the meter by means of bolts, etc. The connection position between the connecting piece 8 and the meter casing needs to ensure that when the meter is plugged in and the bottom of the meter abuts against the upper surface of the plug-in base 1, the clamp 82 can be fully inserted into the plug-in base 1. When the clamp 82 is fully inserted into the plug-in base 1, the moving part 3 moves to the lower position, thereby breaking the short circuit. The meter is not shown in the figure. The meter, the connecting piece 8 and the plug-in base 1 need to be matched. The connection method between the connecting piece 8 and the meter casing is existing technology and can be selected according to the actual situation. Alternatively, the connecting piece 8 and the meter casing can be set as an inseparable whole to further improve the convenience of installation.

[0086] Of course, other methods besides the docking part 8 and the docking mechanism 81 can be used to connect the meter and the positioning part 42, as long as the docking of the meter and the positioning part 42 can be achieved.

[0087] Specifically, the fourth elastic component 83 can be a spring or a combination of a spring and a telescopic rod, and the installation method is the same as that of the second elastic component 48.

[0088] In this embodiment, when the fourth elastic component 83 is in its natural state, the clamping plate 82 is in its initial position. When the ball 86 pushes the clamping plate 82 to move, the fourth elastic component 83 is compressed. When the ball 86 fully enters the docking groove 85, the clamping plate 82 is no longer squeezed by the ball 86, and the clamping plate 82 is reset by the fourth elastic component 83.

[0089] Example 2: Figure 5 , Figure 8 , Figure 9 As shown, this embodiment further includes the following structure based on embodiment one: it also includes a first limiting component 4 for limiting the position of the moving part 3. When the meter and the plug-in base 1 are not connected, the first limiting component 4 restricts the position of the moving part 3 to the lower position, so that the conductive part 21 and the corresponding conductive plate 2 remain in contact. When the meter and the plug-in base 1 are connected, the first limiting component 4 releases the restriction on the moving part 3, and the moving part 3 is adapted to be moved to the upper position to disconnect the contact between the conductive part 21 and the conductive plate 2.

[0090] In this embodiment, the conductive element 21 is connected to the insulating plate 31 and the movable element 3. When the movable element 3 is in the lower position, it cannot move under the restriction of the first limiting component 4, ensuring that it is always in a short-circuit state before the new meter is inserted. When replacing the meter, the new meter is inserted. When the bottom surface of the new meter is in contact with the upper surface of the insertion base 1, the two are connected, and the positioning element 42 is pushed to the locked position. During the pushing process, the positioning element 42 contacts the first limiting component 4 and pushes the first limiting component 4 to move to a position where it does not contact the movable element 3, thereby releasing the restriction on the movable element 3. After the restriction is released, the movable element 3 moves up to the upper position through the elastic element 32, and at the same time drives the insulating plate 31 to move up, so that the conductive element 21 is disconnected from the conductive plate 2, the short circuit is broken, and the current flows through the meter. This method ensures that the short circuit is automatically broken when the meter is fully inserted, avoiding the operator forgetting to disconnect the short circuit after the new meter is replaced, resulting in the current not flowing through the meter.

[0091] like Figure 8-9 As shown, the first limiting component 4 includes a first limiting member 41 that is horizontally slidably disposed on the plug-in base 1. The first limiting member 41 is located below the second limiting member 7. The first limiting member 41 is configured such that when the moving member 3 is moved to the lower position, the first limiting member 41 is in the initial position and inserts into the moving member 3, thereby restricting the moving member 3 to the lower position. When the meter docks with the plug-in base 1, the positioning member 42 is pushed down by the meter, thereby contacting the first limiting member 41 and pushing the first limiting member 41 to move horizontally until it disengages from the moving member 3, so that the moving member 3 is unrestricted and moved to the upper position to disconnect the contact state between the conductive member 21 and the conductive plate 2.

[0092] In this embodiment, in the initial state, the old meter is pulled out, and the moving part 3 is moved to the lower position, so that the short circuit is closed. The first limiting part 41 is partially inserted into the moving part 3 to limit the moving part 3 and keep the short circuit state. At this time, the positioning part 42 does not contact the first limiting part 41. When the new meter is inserted, during the process of the meter pushing the positioning part 42 to the locked position, the positioning part 42 first contacts the first limiting part 41, and then pushes the first limiting part 41 to move horizontally away from the moving part 3. When the new meter is fully inserted (i.e., the positioning part 42 moves to the locked position), the first limiting part 41 is pushed to disengage from the moving part 3. After the moving part 3 loses its limit, it moves upward through the elastic element 32 to break the short circuit, and finally pushes the second limiting part 7 to move to the insertion positioning part 42 through the moving part 3.

[0093] Specifically, such as Figure 8-9 As shown, the movable part 3 is provided with a first limiting groove 43. When the movable part 3 is in the lower position, the first limiting part 41 is partially inserted into the first limiting groove 43.

[0094] Specifically, such as Figure 8-9 As shown, the first limiting member 41 has a through groove 44 that penetrates itself, and a first force-receiving part 45 is provided in the through groove 44. The positioning member 42 has a first pushing part 46 that cooperates with the first force-receiving part 45 at one end near the first limiting member 41. When the positioning member 42 is moved downward, the first pushing part 46 contacts the first force-receiving part 45. As the positioning member 42 continues to move, the first pushing part 46 squeezes the first force-receiving part 45, thereby pushing the first limiting member 41 to move away from the moving member 3. During the horizontal movement of the first limiting member 41, the positioning member 42 extends into the through groove 44 to avoid interference.

[0095] Furthermore, the first pushing part 46 is inclined, and the first force receiving part 45 is arc-shaped.

[0096] The specific process of the coordinated operation of the first limiting member 41, the second limiting member 7, and the positioning member 42 is as follows: When the meter is inserted, the positioning member 42 pushes the first limiting member 41 to move, causing the moving member 3 to lose its limiting position and move upward through the elastic element 32, thereby breaking the short circuit. During the upward movement of the moving member 3, the moving member 3 pushes the second limiting member 7 to move towards the positioning member 42, causing the second limiting member 7 to insert into the positioning member 42 and limit the positioning member 42. In this state, the moving member 3 and the second limiting member 7 always remain in a resisting state, preventing the second limiting member 7 from resetting and preventing the positioning member 42 from moving in the short circuit-broken state. The meter is then connected to the positioning member 42 through the docking mechanism 81, thus preventing the meter from moving in the short circuit-broken state. When the old meter is pulled out while in the disconnected state, the operator must restore the short circuit state before pulling out the old meter when a new meter needs to be replaced. The operator can move the moving part 3 down to the lower position through the handle 6 to close the short circuit, and then manually maintain the short circuit state. At this time, the second limit part 7 will reset synchronously after losing the restriction of the moving part 3. After the second limit part 7 is reset, it will be pulled out of the positioning part 42, so that the positioning part 42 loses its limit. At this time, the old meter can be pulled out. During the process of pulling out the old meter, the positioning part 42 will move up until the positioning part 42 is not in contact with the first limit part 41. After the first limit part 41 loses the limit of the positioning part 42, it will reset to partially insert the moving part 3, restricting the moving part 3 to the lower position, so that the short circuit state is automatically maintained.

[0097] like Figure 8-9 As shown, a first elastic component 47 for resetting the first limiting member 41 is provided between the first limiting member 41 and the insertion base 1.

[0098] Specifically, the first elastic component 47 is adapted to move and reset the first limiting member 41 to partially insert into the moving member 3 when the first limiting member 41 is not in contact with the positioning member 42, thereby restricting the moving member 3 to the lower position.

[0099] In this embodiment, when the first elastic component 47 is in its natural state, the first limiting member 41 is in its initial position and partially inserted into the moving member 3, limiting the moving member 3. When the first limiting member 41 is pushed by the positioning member 42, the first elastic component 47 is compressed, and the moving member 3 loses the restriction of the first limiting member 41. When the positioning member 42 is not in contact with the first limiting member 41, the first elastic component 47 returns to its natural state and drives the first limiting member 41 to move back to partially inserted into the moving member 3. The installation method of the first elastic component 47 is the same as that of the second elastic component 48.

[0100] like Figure 7 As shown, a delay mechanism 5 is provided between the insulating plate 31 and the conductive component 21. When the moving component 3 moves to the upper position, the delay mechanism 5 causes the insulating plate 31 to move a certain distance without contact, and then pushes the conductive component 21 to move until it breaks contact with the conductive plate 2.

[0101] The delay mechanism 5 includes an outer sleeve 51 connected to the conductive element 21 and an inner sleeve 52 vertically slidably disposed inside the outer sleeve 51. The inner sleeve 52 is connected to the insulating plate 31. When the insulating plate 31 is moved upward, the insulating plate 31 causes the inner sleeve 52 to slide inside the outer sleeve 51 first, and then pushes the outer sleeve 51 upward.

[0102] Specifically, such as Figure 7 As shown, the inner sleeve 52 is slidably engaged with the outer sleeve 51 to prevent the inner sleeve 52 from being disconnected from the outer sleeve 51 when it is moved downwards.

[0103] In this embodiment, to ensure that the short circuit is disconnected only after the new meter is fully inserted, a delay mechanism 5 is provided. The inner sleeve 52 is connected to the insulating plate 31, and the movement of the insulating plate 31 is determined by the moving part 3. The moving part 3 is released from its limit only after the new meter is fully inserted. After the moving part 3 is released from its limit, the insulating plate 31 and the inner sleeve 52 are moved upward through the elastic element 32. During the upward movement of the inner sleeve 52, it will first move a short distance within the outer sleeve 51. At this time, the inner sleeve 52 will not move the outer sleeve 51, that is, the conductive plate 2 and the conductive part 21 remain in contact. This short distance changes the logic of inserting the new meter and disconnecting the short circuit from synchronous operation to sequential operation. After the inner sleeve 52 completes the short distance, it pushes the outer sleeve 51 and the conductive part 21 upward, causing the short circuit to disconnect. This setting avoids the automatic disconnection of the short circuit when the new meter is not fully inserted, realizing the disconnection of the short circuit after inserting the meter, avoiding accidental power outages by the user, and improving the stability of meter replacement without power interruption.

[0104] Furthermore, an elastic support corresponding to the conductive element 21 can be provided on the plug-in base 1. The elastic support is located above the conductive element 21 and connected to the conductive element 21. The connection between the elastic support and the conductive element 21 is made of insulating material. The elastic support can be a spring or the like. This setting applies a slight supporting force from top to bottom to the conductive element 21, which can prevent the inner sleeve 52 from accidentally moving the outer sleeve 51 upward due to sliding friction or other factors when it moves in the hollow stroke of the outer sleeve 51, thus preventing the short circuit from being disconnected prematurely. After the inner sleeve 52 has completed its hollow stroke, the force that pushes the outer sleeve 51 upward is greater than the supporting force provided by the elastic support. The elastic support is not shown in the figure.

[0105] Of course, the sliding friction that may occur when the inner sleeve 52 moves during its free stroke can also be overcome by the weight of the conductive component 21 itself.
