Description

Technical Field

[0001] The utility model belongs to the technical field of power communication equipment, and particularly relates to a plug-in type electric energy meter. Background Art

[0002] As a metering device for electric energy, an electric energy meter is a device that must be connected in series on the power consumption line of each power consumption user. At present, the connection method of the incoming and outgoing lines of the terminal block of the electric energy meter basically adopts the method of terminal posts. During the installation process, the wire is inserted into the hole of the terminal post of the terminal block, and then the wire is fixed by tightening the wire with double screws to ensure that the wire is in full contact with the terminal post. In this way, a large amount of labor is required during the installation and replacement of the electric energy meter, and the installation efficiency is low. Moreover, during the on-site installation process, although the installation workers operate in a standardized manner, due to some differences or negligence in personal operations, it is difficult to ensure the installation quality. There are often problems such as incomplete tightening or non-tightening of the screws on-site, resulting in a large contact resistance at the connection of the terminal block, which may cause accidents such as the electric meter being burned out or even catching fire. At the same time, during the installation process, since it is necessary to contact the live metal, it is necessary to cut off the power supply of the associated circuit during the installation process, which has a certain impact on other power consumption users.

[0029] Example:

[0030] As Figures 1-5 shown, in this embodiment, a plug-in type electric energy meter is provided, which is applied to a rapid installation structure of an electric energy meter. The rapid installation structure of the electric energy meter includes a plug-in type electric energy meter and an electric energy meter installation base;

[0031] The plug-in type electric energy meter includes an electric energy meter housing and a terminal block 1; the terminal block 1 is provided with an installation through hole 2 and a detection through hole 3. An insertion and extraction member is arranged in the installation through hole 2. One end of the insertion and extraction member forms an insertion and extraction part with the hole wall surface of the installation through hole 2, and the detection through hole 3 forms a detection part with the other end of the insertion and extraction member; the terminal block 1 is arranged on the electric energy meter housing, and an opening part corresponding to the positions of the insertion and extraction part and the detection part of the terminal block 1 is arranged on the electric energy meter housing;

[0032] The electric energy meter installation base 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, the contact mechanism includes a contact member, the contact member is an elastic member, and the contact member has an adjustable contact part; the terminal mechanism is arranged on the base mechanism;

[0033] The plug-in type electric energy meter is arranged at the electric energy meter installation base. The insertion and extraction part of the plug-in type electric energy meter is connected to the contact mechanism of the electric energy meter installation base, and the ejection part of the ejection mechanism is in contact with the plug-in type electric energy meter.

[0034] In the rapid installation structure of the electric energy meter in this embodiment, the connection structure between the plug-in type 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 type electric energy meter is connected to the contact mechanism of the electric energy meter installation base, the connection between the plug-in type electric energy meter and the electric energy meter installation base is realized. Then, by moving the ejection part to act on the separation of the plug-in type electric energy meter and the electric energy meter installation base, the quick disassembly and quick assembly operations of the plug-in type electric energy meter and the electric energy meter installation base are realized, and the manual requirements in the installation and replacement process of the electric energy meter are minimized to the greatest extent.

[0035] The base mechanism in this embodiment includes a bottom plate member 5 and a base member 6. The bottom plate member 5 is connected to the base member 6. The bottom plate member 5 is used to place the contact mechanism and the terminal mechanism. The base member 6 is used to hinge the ejection mechanism and place the plug-in type electric energy meter. The ejection mechanism includes an ejection link member 7, an operation handle member 8 and an ejection member 9. The ejection link member 7 is hinged to the base mechanism. The ejection member 9 is arranged at both ends of the ejection link member 7 and forms an ejection part. The operation handle member 8 is connected to one end of the ejection link member 7, and one end of the ejection member 9 is in contact with the plug-in type electric energy meter.

[0036] In the above structure, the ejecting link member 7 is hinged to the base mechanism through the structure of a pin. The user can rotate the ejecting link member 7 by operating 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 installation base.

[0037] The specific structure of the plug-in part connected to the contact mechanism in this embodiment is as follows:

[0038] Among them, the terminal block 1 is provided with a through groove, and a plurality of 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 part 11 and a second metal part 12. A plug-in part 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 arranged in the installation through hole 2;

[0039] 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 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 part 11. The first metal part 11 is located between the two U-shaped spring pieces 14.

[0040] Specifically, the bottom plate member 5 is provided with a placement groove 15 for placing the contact mechanism. The base member 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.

[0041] Specifically, the contact mechanism further includes a locking spring member 17. The locking spring member 17 is a triangular structure, including 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.

[0042] In the above structure, after the contact member enters the installation through hole 2, the first metal part 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 member 17, the two U-shaped spring pieces 14 can stably clamp the first metal part 11 to realize the connection between the plug-in part and the contact mechanism. Under the action of the ejecting mechanism, the first metal part 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.

[0043] The plug-in component in the simultaneous plug-in and unplug-in type electric energy meter is a metal component, replacing the traditional copper column structure. The position of its second metal component 12 corresponds to that 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 provided partition plate 10 is used to isolate adjacent plug-in components, playing the role of electrical isolation.

[0044] 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 piece 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.

[0045] The specific structure of the plug-in and unplug-in type electric energy meter in this embodiment further includes:

[0046] 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. The terminal block 1 is arranged on the bottom case 18. The plug-in opening 4 and the detection opening 22 are respectively arranged on the bottom case 18 at the positions corresponding to the plug-in part and the detection part of the terminal block 1. A cover plate 20 is arranged on the upper case 19 at the position corresponding to the terminal block 1. One end of the cover plate 20 is hinged to the upper case 19. A connecting seat is arranged on the cover plate 20, and a first fixing bolt component is arranged on the connecting seat. One end of the first fixing bolt component is connected to the terminal block 1.

[0047] Specifically, a transparent lens 21 is further arranged on the terminal block 1 at the position corresponding to the notch of the through groove.

[0048] Specifically, the upper case 19 is provided with a hook part 23, the bottom case 18 is provided with a clamping part 24 that cooperates with the hook part 23, and the upper case 19 is provided with a connecting hole, and a third fixing bolt component for connecting to the bottom case 18 is arranged on the connecting hole.

[0049] 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.

[0050] The specific structure of the installation base of the electric energy meter in this embodiment further includes:

[0051] 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.

[0052] Among them, the connecting metal sheet 27 plays a role in connecting the internal and external current flows. The second fixing bolt member 26 is provided to lock the external wire and plays a role in internal and external connection.

[0053] 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 shell 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.

[0054] The electric energy meter installation base of this embodiment further includes an anti-stealing electricity cover member capable of covering the contact mechanism and the terminal mechanism. The anti-stealing electricity cover member includes an electric cover body 30 and an electric cover clamping plate 31. 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-stealing electricity 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-stealing electricity.

[0055] 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.

[0056] The above is only a preferred embodiment of the present invention, and it does not impose any form of limitation on the present invention. Therefore, any modification, equivalent change, and modification 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.
