[0036] In the rapid installation structure of the electric energy meter in this embodiment, the connection structure between the plug-in electric energy meter and the electric energy meter installation base is a detachable connection structure. When the insertion and extraction part of the plug-in electric energy meter is connected to the contact mechanism of the electric energy meter installation base, the connection between the plug-in electric energy meter and the electric energy meter installation base is realized. Then, by moving the ejection part to act on the plug-in electric energy meter to separate it from the electric energy meter installation base, the quick disassembly and quick installation operations of the plug-in electric energy meter and the electric energy meter installation base are realized, minimizing the manual requirements during the installation and replacement of the electric energy meter to the greatest extent.

[0037] The base mechanism in this embodiment includes a bottom plate part 5 and a base part 6. The bottom plate part 5 is connected to the base part 6. The bottom plate part 5 is used to place the contact mechanism and the terminal mechanism, and the base part 6 is used to hinge the ejection mechanism and place the plug-in electric energy meter. The ejection mechanism includes an ejection link part 7, an operation handle part 8, and an ejection part 9. The ejection link part 7 is hinged to the base mechanism. The ejection part 9 is arranged at both ends of the ejection link part 7 and forms an ejection part.

[0038] In the above structure, the ejection link part 7 is hinged to the base mechanism through a pin structure. The user can rotate the ejection link part 7 by acting on the operation handle part 8, thereby driving the ejection part 9 to rotate. The ejection part 9 acts on the plug-in electric energy meter to separate the plug-in electric energy meter from the electric energy meter installation base.

[0039] The specific structure of the plug-in part connected to the contact mechanism in this embodiment is as follows:

[0040] Among them, the terminal block 1 is provided with a through groove, and several partition plates 10 are arranged in the through groove. Installation through holes 2 are formed between adjacent partition plates 10 and between the partition plates 10 and the groove wall surface of the through groove. The detection through hole 3 corresponds to the position of the installation through hole 2. The plug-in part is a metal part, including a first metal component 11 and a second metal component 12. A plug-in part is formed between the first metal component 11 and the partition plate 10 or the groove wall surface of the through groove. The second metal component 12 corresponds to the position of the detection through hole 3, and a clamping groove 34 matching the second metal component 12 is arranged in the installation through hole 2;

[0041] The contact part is a metal spring piece, including a contact bottom piece 13 and a U-shaped spring piece 14. The U-shaped spring pieces 14 are respectively arranged at both ends of the contact bottom piece 13. The two U-shaped spring pieces 14 form a contact part. One end of the contact part is located in the installation through hole 2 of the terminal block 1 and is in contact with the first metal component 11. The first metal component 11 is located between the two U-shaped spring pieces 14.

[0042] Specifically, the bottom plate part 5 is provided with a placement groove 15 for placing the contact mechanism, and the base part 6 is provided with a placement through hole 16 corresponding to the position of the placement groove 15. The contact bottom piece 13 is matched with the placement groove 15, and the U-shaped spring piece 14 is placed in the placement through hole 16.

[0043] Specifically, the contact mechanism further includes a locking spring piece 17. The locking spring piece 17 is of a triangular structure and includes two spring locking ends close to each other. The spring locking ends are abutted against the U-shaped spring pieces 14 and make the two U-shaped spring pieces 14 approach each other.

[0044] In the above structure, after the contact part enters the installation through hole 2, the first metal component 11 is located between the two U-shaped spring pieces 14. Under the action of the elastic force of the two U-shaped spring pieces 14 and the elastic force of the locking spring piece 17, the two U-shaped spring pieces 14 can stably clamp the first metal component 11, realizing the connection between the plug-in part and the contact mechanism. Under the action of the ejecting mechanism, the first metal component 11 is separated from between the two U-shaped spring pieces 14, that is, the separation between the plug-in part and the contact mechanism is realized.

[0045] At the same time, the plug-in part in the plug-in type electric energy meter is a metal part, replacing the traditional copper column structure. Its second metal component 12 corresponds to the position of the detection through hole 3. Through this detection through hole 3, the calibration equipment can contact the second metal component 12 to ensure that it can adapt to the crimping calibration of the traditional calibration equipment. The arranged partition plate 10 is used to isolate adjacent plug-in parts and plays an electrical isolation role.

[0046] Meanwhile, the U-shaped structure of the U-shaped spring piece 14 plays a guiding role during the process of entering the installation through hole 2. The arc part of its U-shaped structure facilitates the entry of the first metal component 11 between the two U-shaped spring pieces 14. At the same time, the elastic force of the locking spring piece 17 enables the U-shaped spring piece 14 to closely fit the first metal component 11, completing a fully reliable plugging structure.

[0047] The specific structure of the pluggable electric energy meter in this embodiment further includes:

[0048] The electric energy meter housing includes a bottom case 18 and an upper case 19. The bottom case 18 and the upper case 19 are detachably connected.

A connection seat is arranged on the cover plate 20, and a first fixing bolt member is arranged on the connection seat. One end of the first fixing bolt member is connected to the terminal block 1.

[0049] Specifically, a transparent lens 21 is also arranged at the position corresponding to the notch of the through groove on the terminal block 1.

[0050] Specifically, the upper case 19 is provided with a hook member 23, the bottom case 18 is provided with a clamping member 24 that cooperates with the hook member 23, the upper case 19 is provided with a connection hole, and a third fixing bolt member connected to the bottom case 18 is arranged on the connection hole.

[0051] The provided transparent lens 21 plays a role in preventing electricity theft. At the same time, using a transparent material facilitates seeing the insertion situation during the installation of the electric energy meter through the transparent lens 21 and prevents the problem of electric shock when contacting the live metal components.

[0052] The specific structure of the electric energy meter installation base in this embodiment further includes:

[0053] Specifically, the terminal mechanism includes a moving terminal member 25, a second fixing bolt member 26, and a connecting metal sheet 27. The moving terminal member 25 is connected to the contact member through the connecting metal sheet 27. The moving terminal member 25 has a wire locking groove 28. One end of the second fixing bolt member 26 is located in the wire locking groove 28 and forms a locking part for locking the external wire. A terminal cover 32 covering the terminal mechanism is arranged on the base member in this embodiment. Operation openings 33 are arranged on the terminal cover corresponding to the positions of the wire locking groove and the fixing bolt member.

[0054] Among them, the connecting metal sheet 27 plays a role in connecting the internal and external current flows. The provided second fixing bolt member 26 locks the external wire, playing a role in internal and external connection.

[0055] The base member 6 of this embodiment is provided with four limit baffle members 29 for limiting the plug-in type electric energy meter, and the bottom of the bottom shell 18 is provided with a number of pad bodies in a convex structure to ensure the stable position of the plug-in type electric energy meter.

[0056] The electric energy meter installation base of this embodiment further includes an anti-electricity-stealing cover member that can cover the contact mechanism and the terminal mechanism. The anti-electricity-stealing cover member includes an electric cover body 30 and an electric cover clamping plate 31, and the base mechanism is provided with an electric cover clamping groove that cooperates with the electric cover clamping plate 31. The electric cover clamping plate 31 is of an L-shaped structure. The provided anti-electricity-stealing cover member can cover the exposed metal parts at the contact mechanism and the terminal mechanism when the plug-in type electric energy meter is not installed, preventing accidental contact with the live metal and causing electric shock accidents, and covering the bolt parts of the terminal mechanism to play a role in preventing electricity stealing.

[0057] In summary, this embodiment can solve many problems such as the need for power outage during the installation and replacement of the electric energy meter, high installation man-hours, and unstable installation quality.

[0058] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Therefore, any modifications, equivalent changes, and decorations made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
