Description

Technical Field

[0001] The present invention belongs to the technical field of electricity meter replacement components, and particularly relates to a non-destructive and non-inductive electricity meter replacement component. Background Art

[0002] An electricity meter is a measuring instrument used to measure electricity consumption. It is mainly used to record the active electric energy consumed by electrical appliances, helping families or enterprises to master their electricity usage, thereby contributing to electricity conservation and reducing electricity bills. An electricity meter has a certain service life, and when it reaches the end of its service life, the electricity meter needs to be replaced.

[0003] During the replacement of existing electricity meters, the old electricity meter needs to be disassembled before installing a new one. A short power outage is required during the disassembly and installation of the electricity meter, which brings great inconvenience to users. Summary of the Invention

[0004] The purpose of the present invention is to provide a non-destructive and non-inductive electricity meter replacement component with a simple structure and reasonable design to solve the above problems.

[0005] The present invention achieves the above purpose through the following technical solutions:

[0006] A non-destructive and non-inductive electricity meter replacement component includes a meter base. A watt-hour meter is installed on the front side of the meter base. A wire pressing frame is fixedly connected to the bottom of the meter base. A plurality of wiring holes are formed in the bottom wall of the wire pressing frame. A plurality of L-shaped connection holes are formed in the top wall of the wire pressing frame above the wiring holes. A reed with the bottom fixed to the wire pressing frame is arranged below the horizontal section of the connection hole. An external wire penetrates through the wiring hole and is electrically connected to the reed. A plurality of fixing holes corresponding to the connection holes are formed in the bottom of the watt-hour meter. A conductive column electrically connected to the watt-hour meter is detachably connected in each fixing hole. The middle sections of the plurality of conductive columns are fixed by the same integrated board. A power connection plug board is fixedly connected to one end of the conductive column below the integrated board. The bottom end of the power connection plug board penetrates through the connection hole and extends into the reed and is electrically connected to the reed.

[0007] As a further optimized solution of the present invention, ear plates are integrally formed on the top of the meter base. Through holes are formed in the ear plates, and expansion bolts are slidably inserted through the through holes. The ear plates are fixed to an external building wall through the expansion bolts.

[0008] As a further optimized solution of the present invention, a group of heat dissipation holes are formed on the meter base on both sides of the ear plates, and the two groups of heat dissipation holes are symmetrically arranged.

[0009] As a further optimized solution of the present invention, a hook is fixedly connected to the meter base between the two groups of heat dissipation holes, a card slot is provided on the back of the electric energy meter in alignment with the hook, and the electric energy meter is fixedly connected to the hook through the card slot.

[0010] As a further optimized solution of the present invention, a protective cover is provided outside the wire pressing frame, buckles are installed at both ends of the protective cover, and the protective cover is fixedly connected to the meter base through the buckles.

[0011] As a further optimized solution of the present invention, a separation hole is provided at the top of the reed piece. When the electric energy meter rotates around the connection hole to be perpendicular to the height direction of the meter base, the bottom end of the power connection plug board is located on one side of the separation hole.

[0012] As a further optimized solution of the present invention, the integrated board is made of an insulating material, and limiting plates extend downward on both sides of the integrated board away from the electric energy meter, and connection grooves with the same depth as the height of the limiting plates are provided on the wire pressing frame.

[0013] As a further optimized solution of the present invention, a display electrically connected to the electric energy meter is provided outside the electric energy meter, screws are inserted through the periphery of the display, and the screws are screwed and fixed to the side wall of the ear plate after passing through the frame of the display.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. During use, the user loosens the connection between the old electric energy meter and the hook, turns the old electric energy meter outward by 90 degrees, then inserts the power connection plug board connected to the bottom end of the new electric energy meter through the conductive column into the reed piece inside the power connection plug board connected to the bottom end of the old electric energy meter, so that the new electric energy meter and the old electric energy meter are both connected to the external power supply through the reed piece. After observing that the new electric energy meter runs stably, the user pulls out the power connection plug board connected to the old electric energy meter from the reed piece, and the replacement of the old electric energy meter can be completed. There is no need to cut off the power during the replacement process, which is convenient for users.

[0016] 2. Since the electric energy meter is connected to a plurality of conductive columns passing through the integrated board through fixing holes, and the shapes of both ends of the electric energy meter are different, when installing the electric energy meter, the sliding plug-in connection in a fixed direction can fundamentally avoid the problem of incorrect wiring caused by carelessness during power outage replacement.

Specific embodiments

[0026] The following further describes the present application in detail with reference to the accompanying drawings. It is necessary to point out here that the following specific embodiments are only used to further illustrate the present application and cannot be understood as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0027] Embodiment

[0028] As Figure 1 - Figure 8 shown, a non-destructive and non-inductive electric energy meter replacement component includes a meter base 1. An ear plate 3 is integrally formed on the top of the meter base 1. A through hole is provided in the ear plate 3, and an expansion bolt is slidably inserted through the through hole. The ear plate 3 is fixed to an external building wall through the expansion bolt, so as to stably install the meter base 1 on the external building;

[0029] An electric energy meter 2 is installed on the front side of the meter base 1. A group of heat dissipation holes 4 are provided on the meter base 1 on both sides of the ear plate 3, and the two groups of heat dissipation holes 4 are symmetrically arranged. When the electric energy meter 2 works, the electric energy meter 2 can be dissipated heat through the heat dissipation holes 4 provided on the meter base 1, and try to avoid the problem that the heat generated when the electric energy meter 2 works cannot be discharged in time, resulting in the electric energy meter 2 working in a high-temperature environment for a long time and affecting the service life of the electric energy meter 2;

[0030] A hook 5 is fixedly connected to the meter base 1 between two groups of heat dissipation holes 4. A clamping groove is provided on the back of the electric energy meter 2 and is arranged in alignment with the hook 5. The electric energy meter 2 is fixedly connected to the hook 5 through the clamping groove. When installing the electric energy meter 2, the clamping groove can be aligned with the hook 5, and then the electric energy meter 2 is slid down until the hook 5 is inserted into the clamping groove, so as to realize the relative fixation of the electric energy meter 2 and the meter base 1;

[0031] A wire pressing frame 6 is fixedly connected to the bottom of the meter base 1. A plurality of wiring holes 8 are provided on the bottom wall of the wire pressing frame 6. A plurality of L-shaped connection holes 9 are provided on the top wall of the wire pressing frame 6 above the wiring holes 8. A reed 10 with the bottom fixed to the wire pressing frame 6 is arranged below the horizontal section of the connection hole 9. The reed 10 is made of elastic metal. The external wire penetrates through the wiring hole 8 and is electrically connected to the reed 10 for electrifying the reed 10;

[0032] A protective cover 7 is arranged outside the wire pressing frame 6. Clasps are installed at both ends of the protective cover 7. The protective cover 7 is fixedly connected to the meter base 1 through the clasps. The protective cover 7 made of insulating material is arranged outside the wire pressing frame 6 for sealing the connection hole 9 and improving the safety of the overall device. The clamping connection method is adopted, which is convenient for the installation and disassembly of the protective cover 7;

[0033] A plurality of fixing holes 12 corresponding to the connection holes 9 are provided at the bottom of the electric energy meter 2. A conductive column 13 electrically connected to the electric energy meter 2 is detachably connected in each fixing hole 12. The middle sections of the plurality of conductive columns 13 are fixed by the same integrated board 14. The integrated board 14 is made of insulating material, and limiting plates extend downward on both sides of the integrated board 14 away from the electric energy meter 2. A connection groove with the same depth as the height of the limiting plate is provided on the wire pressing frame 6;

[0034] A power connection plug board 15 is fixedly connected to the end of the conductive column 13 below the integrated board 14. The bottom end of the power connection plug board 15 penetrates through the connection hole 9 and extends into the reed 10 and is electrically connected to the reed 10 to supply power to the electric energy meter 2;

[0035] A partition hole 11 is provided at the top of the reed 10. When the electric energy meter 2 rotates around the connection hole 9 to be perpendicular to the height direction of the meter base 1, the bottom end of the power connection plug board 15 is located on one side of the partition hole 11, so that a space for another group of power connection plug boards 15 to be inserted is left on the other side of the partition hole 11;

[0036] A display 17 electrically connected to the electric energy meter 2 is arranged outside the electric energy meter 2. Screws 16 are penetrated through the periphery of the display 17. The screws 16 penetrate through the frame of the display 17 and are screwed and fixed to the side wall of the ear plate 3 for real-time display of the user's power consumption data through the display 17.

[0037] It should be noted that for this non-destructive and non-inductive electric meter replacement component, when the old electric meter 2 reaches the replacement cycle and needs to be replaced, the user first removes the protective cover 7 from the meter base 1, and then slides the old electric meter 2 upward until the card slot opened on the back of the old electric meter 2 disengages from the hook 5. At this time, the user rotates the old electric meter 2 outward by 90 degrees along the connection hole 9. (During the rotation process, the operator needs to always keep the force of the old electric meter 2 pressing towards the meter base 1 to avoid the old electric meter 2 detaching from the meter base 1 and causing power failure), so that the old electric meter 2 rotates to be perpendicular to the height direction of the meter base 1. At this time, the bottom end of the power connection plug board 15 connected by the conductive column 13 on the old electric meter 2 rotates to the side of the separation hole 11 opened on the reed 10 that is far from the meter base 1. The user can then take the new electric meter 2 at this time, and insert the power connection plug board 15 connected by the conductive column 13 at the bottom of the new electric meter 2 into the separation hole 11 opened on the reed 10 on the side close to the meter base 1, so that the new electric meter 2 and the old electric meter 2 are energized simultaneously. After confirming that there is no error, the power connection plug board 15 connected to the old electric meter 2 is pulled out from the reed 10, and the replacement of the old electric meter 2 can be completed. There is no need to cut off the power during the replacement process, which is convenient for users to use.

[0038] The above-described embodiments merely represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
