[0034] The base for installing the electric energy meter includes a base mechanism, an ejection mechanism, a contact mechanism and a terminal mechanism; the ejection mechanism is hinged to the base mechanism, and the ejection mechanism has an ejection part that can move relative to the base mechanism; the contact mechanism is arranged on the base mechanism, and the contact mechanism includes a contact member, and the contact member has a contact part with adjustable size; the terminal mechanism is arranged on the base mechanism;

[0035] The plug-in electric energy meter is arranged at the base for installing the electric energy meter. The insertion part of the plug-in electric energy meter is connected to the contact mechanism of the base for installing the electric energy meter, and the ejection part of the ejection mechanism is in contact with the plug-in electric energy meter.

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

[0037] The base mechanism of this embodiment includes a base plate member 5 and a base member 6. The base plate member 5 is connected to the base member 6. The base plate member 5 is used to place the contact mechanism and the terminal mechanism, and the base member 6 is used to hinge the ejecting mechanism and place the plug-in type electric energy meter. The ejecting mechanism includes an ejecting link member 7, an operating handle member 8, and an ejecting member 9. The ejecting link member 7 is hinged to the base mechanism. The ejecting member 9 is provided at both ends of the ejecting link member 7 to form an ejecting portion. The operating handle member 8 is connected to one end of the ejecting link member 7. One end of the ejecting member 9 is in contact with the plug-in type electric energy meter.

[0038] In the above structure, the ejecting link member 7 realizes the hinged connection with the base mechanism through the pin structure. The user can rotate the ejecting link member 7 by acting on the operating handle member 8, thereby driving the ejecting member 9 to rotate. The ejecting member 9 acts on the plug-in type electric energy meter to separate the plug-in type electric energy meter from the electric energy meter mounting base.

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

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

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

[0042] Specifically, a placement groove 15 for placing the contact mechanism is provided on the base plate member 5. A placement through hole 16 corresponding to the position of the placement groove 15 is provided on the base member 6. 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 member 17. The locking spring member 17 is of a triangular structure and includes two spring locking ends close to each other. The spring locking ends abut 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 member enters the installation through-hole 2, the first metal component 11 is located between the two U-shaped spring pieces 14. Under the elastic force of the two U-shaped spring pieces 14 and the elastic force of the locking spring member 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 ejection 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 verification equipment can contact the second metal component 12 to ensure that it can adapt to the crimping verification of the traditional verification equipment. The provided isolation plate 10 is used to isolate adjacent plug-in parts, playing the role of electrical isolation.

[0046] At the same time, 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 can facilitate the first metal component 11 to enter between the two U-shaped spring pieces 14. At the same time, the elastic force of the locking spring member 17 can make the U-shaped spring piece 14 closely fit the first metal component 11 to complete a full and reliable plug-in structure.

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

[0048] The electric energy meter housing includes a bottom shell 18 and an upper shell 19. The bottom shell 18 and the upper shell 19 are detachably connected. The terminal block 1 is arranged on the bottom shell 18. The plugging opening 4 and the detection opening 22 are respectively arranged on the bottom shell 18 at the positions corresponding to the plugging part and the detection part of the terminal block 1. A cover plate 20 is arranged on the upper shell 19 at the position corresponding to the terminal block 1. One end of the cover plate 20 is hinged to the upper shell 19. 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 further arranged at the position corresponding to the notch of the through groove on the terminal block 1.

[0050] Specifically, the upper shell 19 is provided with a hook member 23, the bottom shell 18 is provided with a clamping member 24 that cooperates with the hook member 23, and the upper shell 19 is provided with a connection hole, and a third fixing bolt member for connecting to the bottom shell 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 installation base of the electric energy meter in this embodiment further includes:

[0053] Specifically, the terminal mechanism includes a movable terminal member 25, a second fixing bolt member 26, and a connecting metal sheet 27. The movable terminal member 25 is connected to the contact member through the connecting metal sheet 27. The movable 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 portion for locking an external wire. In this embodiment, a terminal cover body 32 for covering the terminal mechanism is provided on the base member. The terminal cover body is provided with an operation opening 33 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 and plays a role in internal and external connection.

[0055] In this embodiment, the base member 6 is provided with four limit baffle members 29 for limiting the plug-in type electric energy meter. The bottom of the bottom case 18 is provided with a plurality 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 capable of covering the contact mechanism and the terminal mechanism. The anti-electricity-stealing cover member includes an electric cover body 30 and an electric cover card plate 31. The base mechanism is provided with an electric cover card slot that cooperates with the electric cover card plate 31. The electric cover card plate 31 is 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 member of the terminal mechanism to play a role in anti-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 is only a preferred embodiment of the present invention, and does not impose any form of limitation on the present invention. Therefore, any modification, equivalent change, and modification made to the above embodiment 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.
