[0036] In the description of this utility model, the terms "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0037] Firstly, this application provides a non-disruptive meter replacement mechanism. For example... Figures 1 to 3 As shown, in some embodiments, the uninterrupted meter replacement mechanism 100 includes a mounting base 110 and a resilient short-circuit assembly 120.

[0038] Mounting base 110 is used to mount electricity meter 200; one side of mounting base 110 is provided with conductive sheet 111, and the conductive sheet 111 is arranged in pairs. In the same pair of two conductive sheets 111, the two conductive sheets 111 are arranged at intervals, one conductive sheet 111 is used to connect to the power source, and the other conductive sheet 111 is used to connect to the power supply system.

[0039] The flexible short-circuit assembly 120 is connected to the mounting base 110; when the energy meter 200 is separated from the mounting base 110, the flexible short-circuit assembly 120 contacts and conducts electricity with the two conductive plates 111 of the same pair. This allows the power supply system to remain connected to the power source through the flexible short-circuit assembly 120 even when the energy meter 200 is temporarily removed from the mounting base 110, thus achieving uninterrupted meter replacement.

[0040] When the electricity meter 200 is installed in the mounting base 110 in a preset direction, the electricity meter 200 pushes the flexible short-circuit component 120 to separate from at least one of the two conductive plates 111 of the same pair. Once the electricity meter 200 is correctly installed, it will directly connect to the conductive plate 111, replacing the function of the flexible short-circuit component 120, thereby restoring normal electricity metering and transmission.

[0041] In this embodiment, the cooperation between the mounting base 110 and the flexible short-circuit component 120 enables the function of uninterrupted power supply when replacing the electricity meter 200, thereby reducing the impact of replacing the electricity meter on users' daily lives and the normal operation of enterprises.

[0042] It should be noted that the power supply system can be a household power supply system, an industrial power supply system, a public facility power supply system, etc., and this application does not limit it. In this application, "uninterrupted power supply" refers to: a brief power outage that is imperceptible to the user; or no power outage at all.

[0043] Specifically, when the electric energy meter 200 is disassembled, the time interval for switching from the electric energy meter 200 to the elastic short-circuit assembly 120 to conduct the power supply and the power supply system is extremely short; when the electric energy meter 200 is installed, the time interval for switching from the elastic short-circuit assembly 120 to the electric energy meter 200 to conduct the power supply and the power supply system is extremely short; the time for power supply switching is within a moment when the electric energy meter 200 is separated from or contacted with the mounting seat 110, and the time interval is less than 1 second, so that the user cannot perceive the influence of power failure.

[0044] For example, the household appliances such as televisions and refrigerators in the household power supply system have a transient power failure protection mechanism, which can quickly respond when the power is suddenly interrupted, protect the internal electronic components from damage, maintain the current working state, and immediately restore to normal after the power is restored, without shutdown, restart and other phenomena, so that the user cannot perceive the influence of power failure.

[0045] Of course, the process of installing and disassembling the electric energy meter 200 can be divided into multiple stages. When the electric energy meter 200 is disassembled, the electric energy meter 200 is first separated from the mounting seat 110 and then moved a distance, and in this stage, the electric energy meter 200 conducts the power supply and the power supply system; until the electric energy meter 200 moves to the first preset position, the electric energy meter 200 and the elastic short-circuit assembly 120 conduct the power supply and the power supply system at the same time, and continue to the second preset position; then the electric energy meter 200 continues to move, the electric energy meter 200 disconnects the power supply and the power supply system, and the elastic short-circuit assembly 120 conducts the power supply and the power supply system.

[0046] When the electric energy meter 200 is installed, the electric energy meter 200 moves a distance, and in this stage, the elastic short-circuit assembly 120 conducts the power supply and the power supply system; until the electric energy meter 200 moves to the first preset position; until the electric energy meter 200 moves to the second preset position, the electric energy meter 200 and the elastic short-circuit assembly 120 conduct the power supply and the power supply system at the same time, and continue to the first preset position; then the electric energy meter 200 continues to move, the elastic short-circuit assembly 120 disconnects the power supply and the power supply system, and the electric energy meter 200 disconnects the power supply and the power supply system.

[0047] That is, during the installation and disassembly process of the electric energy meter 200, the electric energy meter 200 and the elastic short-circuit assembly 120 conduct the power supply and the power supply system at the same time, so that there is no power failure time.

[0048] In some embodiments, a capacitor can also be provided on the circuit electrically connected to the power supply system, so that during the switching time interval of the electric energy meter 200 conducting the power supply and the power supply system and the elastic short-circuit assembly 120 conducting the power supply and the power supply system, the capacitor can be powered, so that there is no power failure time; the present application does not limit this.

[0049] The two pairs of conductive pieces 111 correspond to the live wire and the zero line respectively. Correspondingly, two elastic short-circuit assemblies 120 are arranged to cooperate with the two pairs of conductive pieces 111. In the case of the two pairs of conductive pieces 111, the cooperation between the conductive pieces 111 and the elastic short-circuit assemblies 120 can adopt the same structure or different structures, which is not limited in the present application.

[0050] When the electric energy meter 200 is installed in the mounting seat 110 along the preset direction, the electric energy meter 200 can push the elastic short-circuit assembly 120 to separate from one of the conductive pieces 111, or push the elastic short-circuit assembly 120 to separate from both of the conductive pieces 111, which is not limited in the present application.

[0051] The present application discusses different cooperation modes between a pair of conductive pieces 111 and an elastic short-circuit assembly 120.

[0052] In some embodiments, as shown in Figure 1 and Figure 3 The elastic short-circuit assembly 120 includes an elastic member 121 and a short-circuit piece 122. The elastic member 121 has a certain elasticity and restoring force. One end of the elastic member 121 is connected with the short-circuit piece 122, and the other end of the elastic member 121 is connected with the mounting seat 110. When the electric energy meter 200 is separated from the mounting seat 110, the elastic member 121 will make the short-circuit piece 122 contact and conduct electricity with the two conductive pieces 111 of the same pair by using the restoring force of itself. When the electric energy meter 200 is installed in the mounting seat 110 along the preset direction, the electric energy meter 200 can push the short-circuit piece 122 to separate from one of the conductive pieces 111 or both of the conductive pieces 111 of the pair. The dismounting and mounting actions of the electric energy meter 200 realize the switching of the conduction of the power supply system through the conductive pieces 111 or the electric energy meter 200, without performing additional actions.

[0053] The electric energy meter 200 can directly push the short-circuit piece 122, or push the short-circuit piece 122 through other transmission structures, which is not limited in the present embodiment.

[0054] In some embodiments, the electric energy meter 200 pushes the short-circuit piece 122 through the insulating top block 123.

[0055] As shown in Figure 1 and Figure 3As shown, the insulating top block 123 is connected to the shorting piece 122. When the energy meter 200 is separated from the mounting base 110, the insulating top block 123 is exposed in the mounting base 110. When the energy meter 200 is installed in the mounting base 110 in a preset direction, the energy meter 200 can contact and press against the insulating top block 123, pushing the shorting piece 122 to separate from at least one of the two conductive pieces 111 of the same pair. The insulating top block 123 can improve the insulation performance between the energy meter 200 and the shorting piece 122, avoiding electrical contact or short circuit. The insulating top block 123 can be made of materials such as phenolic resin, epoxy resin, and PVC (polyvinyl chloride).

[0056] There is a gap between the two conductive plates 111 in the same pair, and the insulating top block 123 can pass through the gap between the two conductive plates 111. In this case, when the energy meter 200 pushes the insulating top block 123 to move, the point of action of the insulating top block 123 on the shorting piece 122 tends to be located at the middle position of the shorting piece 122, thereby being able to push the shorting piece 122 to separate from the two conductive plates 111 at the same time.

[0057] In other embodiments, the insulating top block 123 may also contact the edge of the shorting piece 122. Specifically, the two ends of the shorting piece 122 are exposed at the edges of the two conductive pieces 111. The insulating top block 123 provided here will not interfere with the contact between the shorting piece 122 and the conductive pieces 111. Furthermore, the insulating top block 123 may be provided at both ends of the shorting piece 122, so that the energy meter 200 simultaneously pushes the insulating top block 123 to move, so that the shorting piece 122 is simultaneously separated from the two conductive pieces 111.

[0058] like Figure 1 , Figure 3 and Figure 4 As shown, one side of the mounting base 110 has a mounting surface. When the energy meter 200 is installed in the mounting base 110, the bottom surface of the energy meter 200 contacts the mounting surface. A through hole 112 is provided on the mounting surface of the mounting base 110, through which the insulating top block 123 passes. The through hole 112 provides space for the insulating top block 123 to move. When the energy meter 200 is installed in the mounting base 110, the bottom surface of the energy meter 200 is in contact with the mounting surface, and the insulating top block 123 can be pushed to move within the through hole 112.

[0059] When the electric energy meter 200 is separated from the mounting seat 110, the insulating top block 123 extends from the through hole 112, and the insulating top block 123 can protrude from the mounting surface. Thus, when the electric energy meter 200 is mounted on the mounting seat 110, the bottom surface of the electric energy meter 200 first contacts the insulating top block 123, and then the insulating top block 123 is pushed to move so as to separate the shorting piece 122 from the conductive piece 111, until the bottom surface of the electric energy meter 200 is attached to the mounting surface; the protruding size of the insulating top block 123, that is, the distance that the electric energy meter 200 can push the insulating top block 123 to move, so that when the electric energy meter 200 is mounted on the mounting seat 110, there is a gap between the shorting piece 122 and the conductive piece 111.

[0060] When the electric energy meter 200 is separated from the mounting seat 110, the insulating top block 123 can also be flush with the mounting surface or recessed in the mounting surface, in which case the bottom of the electric energy meter 200 needs to be provided with a corresponding protruding structure, so that when the electric energy meter 200 is mounted on the mounting seat 110, the bottom surface of the electric energy meter 200 is attached to the mounting surface, and the protruding structure can extend into the through hole 112 and push the insulating top block 123 to move.

[0061] In other embodiments, the elastic shorting assembly 120 can also not have the insulating top block 123, in which case the bottom of the electric energy meter 200 needs to be provided with a corresponding protruding structure, and the protruding structure is made of an insulating material. When the electric energy meter 200 is mounted on the mounting seat 110, the bottom surface of the electric energy meter 200 can be attached to the mounting surface, and the protruding structure can extend into the through hole 112 and directly push the shorting piece 122 to move.

[0062] In some embodiments, the insulating top block 123 can be connected to the shorting piece 122 as an integral structure by insert molding, buckle connection, screw fastening, etc.; the insulating top block 123 and the shorting piece 122 can also be two independent structures that can move relative to each other.

[0063] In the case that the insulating top block 123 and the shorting piece 122 can move relative to each other, the end of the insulating top block 123 close to the shorting piece 122 is provided with a limiting stop edge 1231, which is used to stop on the mounting seat 110. Through the cooperation of the limiting stop edge 1231 and the mounting seat 110, the movement range of the insulating top block 123 and the conductive piece 111 can be accurately controlled, so as to prevent the insulating top block 123 from moving excessively or even separating from the through hole 112 during the movement.

[0064] As Figure 3 and Figure 5As shown, the limiting flange 1231 can have a certain thickness, and the mounting seat 110 is provided with a sliding channel communicating with the through hole 112. The limiting flange 1231 cooperates with the sliding channel, which can improve the stability of the movement of the insulating top block 123. Moreover, the limiting flange 1231 always keeps part of the structure inside the sliding channel, avoiding dislocation after the limiting flange 1231 and the sliding channel are separated.

[0065] The cross-sectional shape of the insulating top block 123 matches the shape of the through hole 112 on the mounting seat 110, so that the insulating top block 123 can be closely inserted into the through hole 112 and keep a stable position during movement. For example, when the insulating top block 123 is cylindrical, the through hole 112 is a circular through hole; when the insulating top block 123 is a rectangular column, the through hole 112 is a square hole. This shape matching design helps to reduce the shaking and deviation of the insulating top block 123 during movement.

[0066] The size of the through hole 112 should be slightly larger than that of the insulating top block 123, which reduces the friction and wear that the insulating top block 123 may suffer during movement, and facilitates the insulating top block 123 to have enough space for fine adjustment during movement, thereby avoiding jamming or damage caused by friction and wear.

[0067] As shown in Figure 1 , Figure 3 and Figure 5 , the elastic member 121 can adopt a spring or similar component that can recover deformation. The elastic member 121 is located on the side of the short connecting piece 122 away from the conductive piece 111. The main function of the elastic member 121 is to provide a restoring force, so that the short connecting piece 122 can keep in contact with the conductive piece 111 when not subjected to external force. When the electric energy meter 200 is installed on the mounting seat 110, the electric energy meter 200 will compress the elastic member 121, thereby pushing the short connecting piece 122 to move.

[0068] The elastic member 121 and the insulating top block 123 are arranged on opposite sides of the short connecting piece 122, and the insulating top block 123 is aligned with the elastic member 121 along the first direction; wherein the first direction is the moving direction of the short connecting piece 122. Under this layout, the force tends to be transmitted along a straight line, which can reduce or even avoid the deviation of the elastic member 121, thereby ensuring the stability and accuracy of the short connecting piece 122 during movement, and avoiding problems such as poor electrical contact or short circuit caused by the deviation of the elastic member 121.

[0069] Further, the shorting piece 122 is provided with a limiting protrusion 1221 on the side away from the conductive piece 111, and the partial elastic member 121 is sleeved on the outer periphery of the limiting protrusion 1221, so that the connection between the elastic member 121 and the shorting piece 122 is more firm; the limiting protrusion 1221 can also guide the deformation path of the elastic member 121, improve the stability of the movement of the shorting piece 122 in the predetermined direction, and avoid deviation and instability caused by the deformation of the elastic member 121.

[0070] Since the deformation path of the elastic member 121 is effectively guided, the positional accuracy of the shorting piece 122 during movement is significantly improved. Thus, it helps to ensure that the contact state between the shorting piece 122 and the conductive piece 111 is stable and reliable, and avoids problems such as poor electrical contact or short circuit caused by positional deviation.

[0071] The shorting piece 122 is usually a conductive metal piece, such as copper, aluminum, silver or alloy, etc. The limiting protrusion 1221 can be fixed to the bottom of the shorting piece 122 by bonding, welding or the like. It can also be formed by stamping the shorting piece 122 to form a bent portion, and the bent portion serves as the limiting protrusion 1221. This embodiment is not limited in this regard.

[0072] In other embodiments, the shorting piece 122 can be rotatably connected to the mounting seat 110 at one end and connected to the mounting seat 110 at the other end through the elastic member 121. The bottom of the electric energy meter 200 is provided with a protruding structure, and when the electric energy meter 200 is installed on the mounting seat 110, the bottom of the electric energy meter 200 is attached to the mounting surface, and the protruding structure pushes the shorting piece 122 to rotate through the through hole 112, so as to separate from the two conductive pieces 111. This application is not limited in this regard.

[0073] In some embodiments, as shown in Figure 1 , Figure 3 , Figure 6 and Figure 7 , the mounting seat 110 has a mounting space 113, and the mounting space 113 includes oppositely arranged top and bottom walls. The two conductive pieces 111 of the same pair both have a part of the structure arranged in the top wall of the mounting space 113, i.e. the part of the structure of the conductive piece 111 is attached to the top wall of the mounting space 113 or the part of the structure of the conductive piece 111 is embedded in the top wall of the mounting space 113, to achieve firm connection of the conductive piece 111 with the mounting seat 110; avoid deformation of the conductive piece 111 caused by the force generated when the shorting piece 122 contacts the conductive piece 111, and improve the reliability of the circuit conduction. The shorting piece 122 is arranged in the mounting space 113, one end of the elastic member 121 is connected to the shorting piece 122, and the other end of the elastic member 121 is connected to the bottom wall of the mounting space 113. The mounting space 113 not only provides mounting positions for the shorting piece 122 and the elastic member 121, but also limits the movement range of the shorting piece 122, and protects the internal shorting piece 122 and the elastic member 121.

[0074] It should be noted that even if the shorting piece 122 is in contact with the conductive piece 111, the elastic piece 121 is still in a compressed state, so that the shorting piece 122 is tightly pressed against the conductive piece 111, thereby improving the stability of the circuit connection.

[0075] Based on the above embodiment, as shown in Figure 1 、 Figure 3 、 Figure 6 and Figure 7 , the mounting seat 110 includes a base 114 and a bottom plate 115, the base 114 is used for mounting the electric energy meter 200, and the bottom plate 115 cooperates with the base 114 to form a mounting space 113.

[0076] Specifically, the side of the base 114 away from the electric energy meter 200 has a mounting portion 1141, and the two conductive pieces 111 of the same pair both have a part of the structure arranged in the mounting portion 1141. The bottom plate 115 has a mounting groove 1151; the bottom plate 115 is arranged on the side of the base 114 away from the electric energy meter 200. The mounting portion 1141 covers the slot of the mounting groove 1151 to form the mounting space 113, so that the part of the structure of the two conductive pieces 111 is located on the top wall of the mounting space 113. The conductive piece 111 can be mounted on the mounting portion 1141 first, and the elastic shorting assembly 120 is pre-assembled together in the mounting groove 1151, and then the base 114 and the bottom plate 115 are combined, so that the insulating top block 123 of the elastic shorting assembly 120 extends from the through hole 112 on the base 114.

[0077] It should be noted that each pair of conductive pieces 111 corresponds to one mounting groove 1151, and after the bottom plate 115 is assembled with the base 114, the two mounting spaces 113 are not connected with each other, that is, the elastic shorting assembly 120 has an independent space, so that the contact between the two shorting pieces 122 can be avoided to cause the circuit failure.

The thickness of the conductive piece 111 is greater than the depth of the limiting groove, so that the part of the structure of the conductive piece 111 is exposed, and the shorting piece 122 can be in contact with the conductive piece 111.

[0079] The mounting portion 1141 is provided with four ribs, and a limiting groove is formed between the two left ribs and the two right ribs. A sliding channel is formed between the two middle ribs for accommodating the insulating top block 123 and limiting the movement direction of the insulating top block 123.

[0080] The shorting piece 122 is located in the mounting groove 1151, and the size of the shorting piece 122 is greater than the distance between the two conductive pieces 111, so that the shorting piece 122 can be in contact with the conductive pieces 111 in a stable movement path of the shorting piece 122. Alternatively, the size of the shorting piece 122 is greater than the maximum distance between the two conductive pieces 111, so that the shorting piece 122 has sufficient contact area with the conductive pieces 111.

[0082] In other embodiments, the base 114 and the bottom plate 115 can also be fixed together by pressing, bolt fastening or the like, which is not limited in the present application.

[0083] The conductive piece 111 can be a bent metal sheet, and the conductive piece 111 can include a first segment, a second segment and a third segment connected in sequence, the first segment is mounted on the mounting portion 1141, the second segment is embedded in the base 114, and the third segment extends from the mounting surface of the base 114 to form a connection terminal for connecting with a power supply.

[0084] As shown in Figure 1 The base 114 can also be provided with a mounting seat 110, and the mounting seat 110 can be provided with a limiting baffle 116. In some embodiments, the limiting baffle 116 can include four corner structures corresponding to the four corners of the electric energy meter 200. In other embodiments, the limiting baffle 116 can also be a complete side panel structure consistent with the outer edge of the electric energy meter 200, which is not limited in the present application.

[0085] As shown in Figure 1 and Figure 7As shown, in order to improve the disassembly efficiency of the electric energy meter 200, the mounting seat 110 can also be provided with a quick release structure 130. In some embodiments, the quick release structure 130 includes a pull rod 131, a rotating shaft 132 and a pushing piece 133, which can be an integral structure, or can realize torque transmission through other structures. The rotating shaft 132 is rotationally connected with the mounting seat 110, and the pull rod 131 is located on one side of the mounting seat 110. When the electric energy meter 110 is installed on the mounting seat 110, the pushing piece 133 is located at the bottom of the electric energy meter 200, and the pull rod 131 is located on the outer side of the electric energy meter.

[0086] When the electric energy meter 200 needs to be disassembled, the pull rod 131 can be operated. By rotating the pull rod 131, the rotating shaft 132 can be driven to rotate, so that the pushing piece 133 pushes the electric energy meter 200 away from the mounting surface. The mounting surface on the mounting seat 110 is provided with a receiving groove, and when the electric energy meter 110 is installed on the mounting seat 110, the pushing piece 133 is placed in the receiving groove; rotating the pull rod 131 drives the rotating shaft 132 to rotate, so that the pushing piece 133 extends out of the receiving groove to push the bottom of the electric energy meter 200.

[0087] In a second aspect, the present application also provides a metering box. As shown, Figures 1 to 3 In some embodiments, the metering box includes an electric energy meter 200 and a non-power-off meter changing mechanism 100 as described in the first aspect, and the electric energy meter 200 is detachably connected with the mounting seat 110. The disassembly action of the electric energy meter 200 can switch whether the power supply system is conducted through the conductive sheet 111 or the electric energy meter 200, without performing additional actions.

[0088] The embodiments of the present application are described in detail above with reference to the drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit of the present application.
