Description

Technical Field

[0001] This invention relates to the field of electricity meters, specifically to an electricity meter that facilitates automatic wire stripping and wiring. Background Technology

[0002] An electricity meter is an instrument used to measure electrical energy. It is also called an electricity meter, kilowatt-hour meter, or kilowatt-hour meter. It refers to an instrument that measures various electrical quantities. A wall-mounted electricity meter is an electricity meter that is fixed to a wall for use through a fixed installation method.

[0003] Currently, when wall-mounted energy meters on the market need to be wired, it is usually necessary to manually strip the wire ends with a wire stripper, insert them into the terminal block, and then tighten the bolts to fix the wires to the terminal block. The whole process requires electricians to not only strip the outer insulation layer of each wire end, but also to manually tighten the bolts to fix the wire ends. This is not only time-consuming and labor-intensive, but also sometimes requires live work in special circumstances.

[0004] CN111981265A discloses a stable wall-mounted energy meter, including an energy meter body, a frame mounted on one side of the energy meter, a first bearing mounted on the upper end of the frame, and a second bearing mounted on the lower end of the frame. A rotating shaft is provided between the second bearing and the first bearing, and a rotating device is mounted on the upper end of the rotating shaft. A clamping device is provided in the middle of the rotating shaft, and the clamping device is in contact with a mounting bracket. An energy meter box is mounted on one side of the mounting bracket, and a first anti-vibration device is installed inside the energy meter box. Through the arrangement of the frame, rotating shaft, clamping device, mounting bracket, energy meter box, first anti-vibration device, and second anti-vibration device, the energy meter can be fixed by simply rotating the rotating device. The operation is simple and efficient, and it is convenient to install and disassemble. At the same time, the first and second anti-vibration devices effectively prevent the energy meter from being affected by external vibrations during operation, protecting the precision parts inside the energy meter.

[0005] CN112255441A discloses a wall-mounted electric meter box for easy installation, including a box body, a cover, a rain shield, inlet and outlet ports, heat dissipation holes, and a mounting base. A mounting base is fixedly installed on the rear side of the box body, and a connecting base is fixedly installed on the surface of the mounting base. The top of the connecting base has a downwardly recessed snap-fit ​​groove, within which a horizontal support column is fixedly installed. The bottom of the mounting base has an upwardly extending snap-fit ​​groove, into which the support column snaps, connecting the mounting base and the connecting base together. The connecting base is equipped with an adjustment mechanism that pushes the box body to change its tilt angle. A vertical angle adjustment support block is fixedly installed on the rear side wall of the box body corresponding to the adjustment mechanism. This technology uses an independent mounting base to install the box on the wall, and then uses the connecting base and mounting base to mount the box on the wall, making installation convenient and quick. Furthermore, the mounting base uses a snap-fit ​​method, ensuring a secure connection and preventing shaking.

[0006] Therefore, it is clear that the existing technology cannot solve the technical problem of this invention. Summary of the Invention

[0007] This invention provides an energy meter that facilitates automatic wire stripping and wiring, offering the advantages of convenient automatic wire stripping and wiring, and requiring less manual intervention when live-line work is needed.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] In this invention, as the fixed rod and the ball continue to move, the first pressure plate rotates synchronously with the rotation of the rotating cylinder. The synchronous rotation of the first and second pressure plates maintains the cutting of the outer ring of the wire by the corresponding cutting blades. That is, after the two cutting blades press and cut, they rotate and cut around the wire, which can cut the insulation layer at the cutting end more evenly. It should be noted that, due to the action of the torsion spring, the initial position of the fixed rod and the ball aligned with the opening of the spiral groove can be directly slid into the spiral groove.

[0023] In this invention, as the third pressure plate moves closer, it presses down on the sleeve. After being pressed, the sleeve moves downward with the force of the corresponding first pressure plate. As the first pressure plate gets closer and closer to the second pressure plate, the cutting blades between the first and second pressure plates will move closer to each other and cut the corresponding position of the wire. The cutting position is the section of the wire exposed outside the cutting blade.

[0024] In this invention, as the first moving frame continues to move, the two clamping cutting blades peel off the insulation layer from the cut end of the connector wire. Continuing to move the first and second moving frames causes the second moving frame to pass the clamped connector wire through the first moving frame, exposing the stripped end, and gradually move towards the circular frame and the terminal block. As the connector wire end gradually inserts into the terminal block, the rack engages with the gear, causing the gear to rotate. The rotation of the gear causes the corresponding bolt to rotate and move downwards along the threaded connection of the terminal block, causing the pressure plate at the bolt end to move downwards along the wiring hole, and the pressure plate gradually presses down on the connector wire end inserted into the wiring hole.

[0049] An abutment block 47 is fixed to the outer wall of the lifting plate 45, and an inclined surface 48 is provided on the outer wall of the abutment block 47.

[0050] A display 4 is installed on the inner wall of the electricity meter casing 1, and the display 4 is electrically connected to the terminal block 5.

[0051] In this embodiment: an electricity meter is an instrument used to measure electrical energy, also known as an electricity meter, watt-hour meter, or kilowatt-hour meter. It refers to an instrument that measures various electrical quantities. A wall-mounted electricity meter is an electricity meter that is fixed to the wall for use through a fixed installation method.

[0052] Currently available wall-mounted electricity meters typically require manual intervention when wiring. This involves first stripping the insulation from each wire end with a wire stripper, then inserting it into the terminal block, and finally tightening the bolts to secure the wire to the terminal block. This process is time-consuming and labor-intensive, and in some special circumstances, it may even require live-line work. Therefore, a multi-functional wall-mounted electricity meter is needed.

[0053] To facilitate wiring, when using this electricity meter, first insert the connecting wire 3 into the meter casing 1, then continue threading it between the first pressure plate 21 and the second pressure plate 25 until one end protrudes a short distance beyond the first pressure plate 21 and the second pressure plate 25 near the first movable frame 12. At this point, activate the electric telescopic rod 2. After activation, the electric telescopic rod 2 moves the first movable frame 12 at the output end. During the movement of the first movable frame 12, it will move along with the first spring 13. The first spring 13 has a large elastic force, and without being stretched, it can move the second movable frame 14. As the second movable frame 14 moves, the guide rod 32 corresponding to the second movable frame 14 slides along the first track groove 29. When it continues to slide after passing the second track groove 30, The two adjacent guide rods 32 are brought closer together by the force. At this time, the two guide rods 32, along with the corresponding third pressure plate 33, move closer together along the guide of the first guide rod 34, and finally press the two semi-circular third pressure plates 33 together, so that their inner contours form a complete circle. As the third pressure plate 33 moves closer, the third pressure plate 33 will press the sleeve 27. After the sleeve 27 is pressed, the corresponding first pressure plate 21 moves downward with the force. As the first pressure plate 21 gets closer and closer to the second pressure plate 25, it causes the first pressure plate 21 to slide along the outer wall of the first fixed block 18 through the first sliding groove 20, which will tightly clamp the connecting wire 3 between the first pressure plate 21 and the second pressure plate 25. Therefore, the connecting wire 3 will move synchronously with the second moving frame 14 and the first moving frame 12 because it is clamped.

[0054] As the first moving frame 12 and the second moving frame 14 continue to move, the guide rod 32 corresponding to the first moving frame 12 will slide from the fourth track groove 35 to the fifth track groove 36. Due to the track guiding effect of the fifth track groove 36, the two adjacent guide rods 32 will move closer to each other. At this time, the two guide rods 32 will bring the corresponding third pressure plate 33 closer to each other. After they move closer, the third pressure plate 33 will move closer to each other along the guide of the first guide rod 34, and finally press the two semi-circular contours of the third pressure plate 33 together, so that their inner contours form a complete circle. As the third pressure plate 33 moves closer, the third pressure plate 33 will press the sleeve 27. After the sleeve 27 is pressed, the corresponding first pressure plate 21 will move downward under force. As the first pressure plate 21 gets closer and closer to the second pressure plate 25, the cutting blade 40 between the first pressure plate 21 and the second pressure plate 25 will move closer to each other and cut the corresponding position of the connecting wire 3. The cutting position is the section of the connecting wire 3 exposed outside the cutting blade 40.

[0055] As the electric telescopic rod 2 continues to advance, it carries the first movable frame 12 and the second movable frame 14. During this movement, the fixed rod 41 on the outer wall of the second pressure plate 25 corresponding to the first movable frame 12 moves along with it. When the guide rod 32 corresponding to the first movable frame 12 slides along the fifth track groove 36 into the sixth track groove 37, and then continues to slide along the sixth track groove 37 into the seventh track groove 38, this continued sliding causes the fixed rod 41 on the outer wall of the second pressure plate 25 corresponding to the first movable frame 12 to slide along with the ball bearing 42 into the spiral groove 11 on the outer wall of the circular frame 10. As the fixed rod 41 and the ball bearing 42 continue to move, the ball bearing 42 moves along the inner wall of the spiral groove 11 and is guided by the spiral groove 11. The continued movement of the fixed rod 41 and the ball bearing 42 causes the ball bearing 42 and the fixed rod 41 to be guided by the spiral groove 11. The guide function of groove 11 is subjected to force and rotates in a circular motion. The rotation of fixed rod 41 causes the corresponding second pressure plate 25 to rotate synchronously. The rotation of second pressure plate 25 will cause the second fixed block 22 to rotate together. The rotation of second fixed block 22 will cause the rotating cylinder 16 to rotate together. While rotating along the outer wall of the first moving frame 12, the rotating cylinder 16 will twist the torsion spring 17 to facilitate subsequent reset. At this time, as the rotating cylinder 16 rotates, the first pressure plate 21 also rotates synchronously. The synchronous rotation of the first pressure plate 21 and the second pressure plate 25 maintains the cutting of the corresponding cutting blade 40 to the outer ring of the wire 3. That is, after the two cutting blades 40 press and cut, they rotate and cut around, which can cut the insulation layer at the cutting end more evenly. It should be noted that, due to the action of torsion spring 17, the initial position of fixed rod 41 and ball 42 aligned with the groove opening of spiral groove 11 can directly slide into spiral groove 11.

[0056] As the first moving frame 12 and the second moving frame 14 continue to move, the guide rod 32 on the outer wall of the second moving frame 14 will be obstructed by the blocking block 46 and unable to continue moving as it slides along the third track groove 31. Meanwhile, the first moving frame 12, which continues to move, will continue to move by stretching the first spring 13. The continued movement of the first moving frame 12 will cause the two pressed cutting blades 40 to peel off the insulation layer of the cut wire 3 from the end of the wire 3. 2. Continuing to slide along the sixth track groove 37 will cause the guide rod 32 to abut against the inclined surface 48 on the outer wall of the abutment block 47, thereby causing the abutment block 47 to be subjected to upward force. The upward force on the abutment block 47 will cause the lifting plate 45 and the blocking block 46 to slide upward along the outer wall of the second guide rod 43, and during the movement, the third spring 44 will be compressed to facilitate subsequent reset. At this time, the upward movement of the blocking block 46 will release the obstruction to the guide rod 32 corresponding to the second moving frame 14. At this time, the first spring 13 will quickly rebound, and the rebound of the first spring 13 will cause the second moving frame 14 to slide upward. The moving frame 14 rapidly approaches the first moving frame 12. At this time, the second moving frame 14 moves synchronously with the connecting wire 3. Meanwhile, the electric telescopic rod 2 is activated, causing the first moving frame 12 to continue moving. The guide rod 32 corresponding to the first moving frame 12 will slide from the sixth track groove 37 into the seventh track groove 38. Continued sliding will release the close clamping state of the two cutting blades 40. At this time, if the first moving frame 12 and the second moving frame 14 continue to move, the second moving frame 14 will pass through the first moving frame 12 with the clamped connecting wire 3. 2. The stripped wire end is exposed and gradually moves towards the circular frame 10 and the terminal 5. When the end of the wire 3 is gradually inserted into the terminal 5, the rack 15 will also mesh with the gear 6. The meshing causes the gear 6 to rotate. The rotation of the gear 6 will cause the corresponding bolt 7 to rotate and move down along the threaded connection of the terminal 5. This causes the pressure plate 8 at the end of the bolt 7 to move down along the wiring hole 9. The pressure plate 8 gradually presses the end of the wire 3 inserted into the wiring hole 9, fixing it inside the wiring hole 9, thus completing the entire wiring process.

[0057] Therefore, the entire process only requires personnel to insert the connecting wire 3 and start the electric telescopic rod 2. Finally, the wall-mounted energy meter can be installed on the wall using external tools such as expansion bolts.
