The flip mechanism 2 is provided with a short-circuit 5 and is located at the entrance between the two conductive terminal heads 4. When the flip mechanism 2 is rotated, the electrical connection between the conductive terminal head 4 and the wiring terminal 3 is interrupted, so that the short-circuit 5 abuts against the two conductive terminal heads 4, so that the user does not disconnect the power when replacing the meter;

[0030] It is worth mentioning that the wiring base 1 is provided with a concave cavity 11, the concave cavity 11 is provided with a plurality of first fixing grooves 12, the first fixing groove 12 is provided with a wire hole 13, the concave cavity 11 is provided with a circuit board 6, and is electrically connected to the short-circuit 5, the circuit board 6 is provided with an LED lamp 61, the concave cavity 11 is provided with a cover 7, and both sides of the wiring base 1 are provided with a clearance through hole 14 and a clearance groove 15. The concave cavity 11 provides a storage space for the wiring terminal 3 and the circuit board 6. The first fixing groove 12 is used in conjunction with the wiring terminal 3, and the circuit board 6 is used in conjunction with the LED lamp 61. The cover 7 is convenient for maintenance personnel to replace or repair the parts in the concave cavity 11. The clearance through hole 14 is long and strip-shaped, which is convenient for the anti-theft cover plate 8 to move upward and hingedly.

[0031] It is worth mentioning that an anti-electricity theft cover 8 is provided on the front of the wiring base 1. One end of the anti-electricity theft cover 8 is hinged to the clearance through hole 14. By rotating the anti-electricity theft cover 8, the other end is inserted into the clearance groove 15. The anti-electricity theft cover 8 is set to be transparent. A lead seal is applied to the tail cover of the electric energy meter so that the anti-electricity theft cover 8 is locked. The anti-electricity theft cover 8 also prevents non-staff from operating the flip mechanism 2. The transparent anti-electricity theft cover 8 is convenient for staff to observe whether the connection terminal 3 is stably connected to the wire during daily maintenance.

[0032] It is worth mentioning that the wiring terminal 3 is inserted into the first fixing groove 12, and the head of the wiring terminal 3 is provided with a hook groove 31, the wiring terminal 3 is connected to the wire, the hook groove 31 is used in conjunction with the plug 43, and the elastic force of the spring tube 44 acts on the wiring terminal 3, so that the plug 43 and the hook groove 31 are tightly connected, thereby increasing the contact area between the two;

[0033] It is worth mentioning that the flip mechanism 2 is provided with a snap joint 21, and is buckled on the wiring base 1. The flip mechanism 2 is provided with a plurality of second fixing grooves 22. A baffle 23 is provided at the rear between each two second fixing grooves 22. Both sides of the flip mechanism 2 are provided with convex bumps 24, which abut against the wiring base 1. Both sides of the flip mechanism 2 are provided with flip-in-place indicator lines 25. In the case of not replacing the electric energy meter, the flip mechanism 2 is connected and fixed to the wiring base 1 through the snap joint 21. In addition, the snap joint 21 is elastic. The second fixing groove 22 is used in conjunction with the conductive terminal head 4. The baffle 23 provides strong support for the short-circuit 5. The convex bump 24 fixes the flip mechanism 2 in the rotated position. When the flip-in-place indicator lines 25 are parallel to the two sides of the wiring base 1, it represents that the flip mechanism 2 is rotated in place.

[0034] It is worth mentioning that the conductive terminal head 4 is installed and inserted in the second fixing groove 22, and reinforcing ribs 26 are provided on both sides of the second fixing groove 22 and abut against the conductive terminal head 4. The reinforcing ribs 26 enable the conductive terminal head 4 to be connected and fixed to the second fixing groove 22 by interference fit;

[0035] It is worth mentioning that the conductive terminal head 4 is provided with an avoidance through hole 41, and the side wall of the avoidance through hole 41 is provided with a first spring sheet 42, which abuts against the terminal 3, and the first spring sheet 42 is provided with ear buckles 421 on both sides, which are buckled on both sides of the avoidance through hole 41, and the avoidance through hole 41 is provided with a plug 43, which passes through the first spring sheet 42 and abuts against the hook groove 31, and the conductive terminal head 4 is provided with a spring tube 44, which abuts against the terminal 3, and the first spring sheet 42 acts on the terminal 3, so that the conductive terminal head 4 and the terminal 3 are electrically connected stably, the ear buckle 421 facilitates the connection and fixation of the first spring sheet 42 and the avoidance through hole 41, the plug 43 is used in conjunction with the hook groove 31, and the spring tube 44 enables the conductive terminal to be stably connected to the electric energy meter in an interference fit manner;

[0036] The short-circuit 5 is fixedly mounted on the baffle 23, and outwardly expanding second spring pieces 51 are provided on both sides of the short-circuit 5. The second spring pieces 51 ensure that the short-circuit 5 can be stably electrically connected to the two connecting terminals 3. At the same time, the force released by the second spring pieces 51 still fixes the flip mechanism 2 in the rotated position.

[0037] The use principle of the utility model is now described as follows:

[0038] When the electric energy meter needs to be replaced, the lead seal on the electric energy meter is removed so that the anti-electricity theft cover plate 8 can move freely. At this time, an upward force is applied to the anti-electricity theft cover plate 8 so that one end of the anti-electricity theft cover plate 8 leaves the yield groove 15 and the other end moves upward in the yield through hole 14. The anti-electricity theft cover plate 8 is rotated so that the flip mechanism 2 can rotate freely.

[0039] Press the two sides of the electric energy meter and apply an outward pulling force. Through the chamfer on the snap connector 21, the snap connector 21 smoothly leaves the part connected with the snap connector 21. Then, the flip mechanism 2 is rotated to make the latch 43 leave the hook groove 31. The electrical connection between the conductive terminal head 4 and the wiring terminal 3 is interrupted. The short-circuit 5 enters between the two wiring terminals 3. The second spring 51 acts on the wiring terminal 3. The current in the wire passes through the short-circuit 5 and the circuit board 6, so that the LED light 61 lights up to inform the staff that the baffle 23 is above the wiring terminal 3. At this time, the effect of the user not being disconnected from the power supply when the electric energy meter is replaced is completed. Since the conductive terminal head 4 is not charged at this time, it is safer to replace the electric energy meter.

[0040] After the replacement of the electric energy meter is completed, an opposite force is applied to the flip mechanism 2, and the short-circuit 5 leaves between the two terminals 3. At the same time, the spring tube 44 gradually applies a force to the head of the conductive terminal head 4 along the chamfer of the head of the terminal 3, so that it is stretched outward and the connection with the electric energy meter is more stable. The first spring piece 42 is squeezed by the terminal 3 and releases the elastic force to the terminal 3, so that the terminal 3 and the conductive terminal head 4 are electrically connected stably. The pin 43 enters the hook groove 31, and the snap connector 21 is reconnected and fixed to the wiring base 1. The anti-theft cover plate 8 can be reset according to the reverse steps above. At this point, the replacement and disassembly of the electric energy meter can be completed without power outage through the above operation steps.

[0041] The above design scheme can make the product easy to plug and unplug, simple to operate, safe and reliable.

[0042] The above content is a further detailed description of the utility model in combination with specific implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, they can also make several simple deductions or substitutions, which should be regarded as belonging to the scope of protection determined by the claims submitted for the utility model.
