Description

Technical Field

[0001] This utility model belongs to the field of electricity meter technology and relates to an electricity meter that is easy to wire. 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. When wiring an electricity meter, workers need to pull the wire taut, push one end of the wire firmly into the wiring hole, and simultaneously turn the wiring bolt. This operation is very inconvenient and severely reduces work efficiency. Therefore, an electricity meter that is easy to wire is needed.

[0003] A convenient power meter for wiring is disclosed in Chinese patent CN221465621U. The power meter body has wiring holes evenly distributed at the lower end of the power meter body. A wiring bolt is movably inserted through one side of the wiring hole. A protective box is fixedly installed at the lower end of the power meter body. The protective box is located below the wiring holes. The lower end of the protective box has insertion holes evenly distributed below the wiring holes.

[0004] When wiring this electricity meter, the wire needs to be inserted into the wiring hole, and then the slider is pushed to position the wire. This means that during the positioning process, the operator still needs to hold the wire at the wiring hole, making it inconvenient to use.

[0005] To solve the above problems, this utility model proposes an energy meter that is easy to wire. Utility Model Content

[0006] To address the problems existing in the background technology, this utility model proposes an energy meter that is easy to wire.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: it includes an electricity meter body and a junction box. The junction box is fixedly installed at the bottom of the electricity meter body. The bottom of the junction box is provided with a number of wiring holes spaced apart. The top of each wiring hole is vertically slidably connected to a sliding ring by a first spring.

[0008] The bottom of the junction box is fixedly connected to a protective frame, and several limiting frames are fixedly connected at intervals inside the protective frame. The number of limiting frames is equal to that of the sliding ring and they correspond one-to-one. On the side of each limiting frame, two arc-shaped clamps are symmetrically and horizontally slidably arranged by a second spring.

[0009] Two abutment members are symmetrically fixed on the outer surface of each sliding ring. The two abutment members on the sliding ring correspond one-to-one with the two arc-shaped clamps on the corresponding limiting frame. When the sliding ring moves upward, the two abutment members cooperate to drive the two arc-shaped clamps to move closer to each other.

[0010] Furthermore, the bottom end of the first spring is fixedly connected to the top surface of the sliding ring, and each sliding ring is provided with several first springs at its top. The several first springs are arranged in a circumferential array about the sliding ring, and the top end of the first spring is fixedly connected to the top surface of the corresponding wiring hole.

[0011] Furthermore, the abutment includes an L-shaped connecting rod, which consists of a vertical section and a horizontal section. The end of the horizontal section is fixedly connected to the outer surface of the sliding ring, and the connecting rod is vertically slidably connected to the inside of the wiring hole. The end of the vertical section is provided with an inclined surface, which gradually slopes downward from one end near the limiting frame to the other end.

[0012] Two arc-shaped clamps located on the same limiting frame have sliding frames fixedly connected to their opposite sides. The sliding frames are horizontally arranged and have through holes. The bottom end of the connecting rod is slidably set in the corresponding through hole. The second spring is set inside the sliding frame, and one end of the second spring is fixedly connected to the inner wall of the sliding frame.

[0013] Inside the protective frame, there are partitions fixedly connected between two adjacent limiting frames. The limiting frames at both ends are located between the partitions at the ends and the sides of the protective frame. The other end of the second spring at both ends is fixedly connected to the inner wall of the protective frame, and the other end of the remaining second spring is fixedly connected to one side of an adjacent partition.

[0014] Furthermore, a lever is fixedly connected to the bottom of each sliding frame at the end away from the arc-shaped clamp.

[0015] Furthermore, the protective frame has a limit plate fixedly connected to both sides of each limit frame, and the sliding frame slides horizontally through the corresponding limit plate.

[0016] Furthermore, the arc-shaped clamps are arc-shaped, and the two arc-shaped clamps located on the same limiting frame have a rubber layer on their adjacent sides.

[0017] Furthermore, the two bottom ends of the two limiting plates located on the same limiting frame are rotatably connected to a rotating shaft, and a protective plate is fixedly sleeved on each rotating shaft, with the protective plate located below the limiting frame.

[0018] A protrusion is fixedly installed directly below each shaft, and the protrusion is fixedly connected to the inner wall of the protective frame. The protective plate is movably installed on the top of the corresponding protrusion.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. This easy-to-connect electricity meter is equipped with a connecting rod. The end of the connecting rod is movably positioned inside the sliding frame. When a wire is inserted into the wiring hole, the wire core moves upward into the sliding ring, while the wire insulation is blocked by the bottom surface of the sliding ring. As the wire continues to move upward, the insulation drives the sliding ring upward, causing the connecting rod to move upward. The bottom end of the connecting rod leaves the sliding frame, and the second spring pushes the sliding frame to slide inward into the limiting frame, causing the two arc-shaped clamps on the limiting frame to move closer together, thereby fixing the wire. This allows the wire to be fixed during movement without the need for manual clamping, making operation simple.

[0021] 2. The easy-to-wire electricity meter is equipped with a sliding ring. The sliding ring is set in the wiring hole by a first spring. When disconnecting the wire, the sliding frame is pushed to the outside of the limit frame by the lever, so that the arc-shaped clamp is away from the wire. At the same time, the sliding frame moves at the bottom of the connecting rod. Then the first spring will push the sliding ring down, move the bottom end of the connecting rod back to the sliding frame, and automatically reset the sliding ring for reuse.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1-5 As shown, the technical solution adopted by this utility model is as follows: A power meter that is easy to wire includes a power meter body 1 and a junction box 2, wherein the junction box 2 is fixedly installed at the bottom of the power meter body 1. The junction box 2 is a box that connects the power meter and the wires, and is a connector designed to protect the power meter and prevent damage to the power meter caused by circuit faults. The junction box 2 is an existing product.

[0030] The bottom of the junction box 2 is provided with several wiring holes 7 spaced apart, through which wires can be inserted into the junction box 2 for wiring.

[0031] Each wiring hole 7 on the junction box 2 is threaded with a fastening bolt 4. By rotating the fastening bolt 4, the end of the fastening bolt 4 is fixed to the wire, thereby securing the wire. The technique of using fastening bolts 4 to fix the wire has been disclosed in the patent CN221465621U mentioned in the background art, and is prior art, so it will not be described in detail here.

[0032] Each wiring hole 7 has a sliding ring 8 vertically slidably connected to its top via a first spring 9.

[0033] The bottom end of the first spring 9 is fixedly connected to the top surface of the sliding ring 8. Several first springs 9 are provided on the top of each sliding ring 8, and the several first springs 9 are arranged in a circumferential array about the sliding ring 8. The top end of the first spring 9 is fixedly connected to the top surface of the corresponding wiring hole 7.

[0034] A protective frame 3 is fixedly connected to the bottom of the junction box 2. Several limiting frames 14 are fixedly connected at intervals inside the protective frame 3. The number of limiting frames 14 is equal to the number of sliding rings 8, and they correspond one-to-one vertically. The limiting frames 14 and the corresponding sliding rings 8 are coaxially arranged, allowing the wire to pass through the limiting frames 14 and be inserted into the wiring hole 7.

[0035] Two arc-shaped clamps 13 are symmetrically and horizontally slidably mounted on the side of each limiting frame 14 via a second spring 12. The two arc-shaped clamps 13 can be brought close together to fix the wires inside the limiting frame 14.

[0036] The curved clamp 13 is curved, and the two curved clamps 13 located on the same limiting frame 14 have a rubber layer on their adjacent sides. This ensures that the rubber layer is in contact with the wire when the curved clamp 13 clamps the wire.

[0037] Two abutment members are symmetrically fixed on the outer surface of each sliding ring 8. The two abutment members on the sliding ring 8 correspond one-to-one with the two arc-shaped clamping plates 13 on the corresponding limiting frame 14. When the sliding ring 8 moves upward, the two abutment members cooperate to drive the two arc-shaped clamping plates 13 to move closer to each other. The abutment members drive the corresponding arc-shaped clamping plate 13 to move.

[0038] The abutment includes an L-shaped connecting rod 10. The connecting rod 10 consists of a vertical section and a horizontal section, with the end of the horizontal section fixedly connected to the outer surface of the sliding ring 8. The connecting rod 10 is vertically slidably connected to the inside of the wiring hole 7, and the positioning of the connecting rod 10 ensures that the sliding ring 8 can only slide up and down within the wiring hole 7.

[0039] The vertical section has a slope at its end, which gradually slopes downward from one end near the limiting frame 14 to the other end.

[0040] Two arc-shaped clamping plates 13 located on the same limiting frame 14 are each fixedly connected to a sliding frame 11 on their opposite sides. The sliding frame 11 is horizontally arranged, allowing the sliding frame 11 to move the arc-shaped clamping plates 13.

[0041] Inside the protective frame 3, limit plates 16 are fixedly connected to both sides of each limit frame 14, and the sliding frame 11 slides horizontally through the corresponding limit plate 16. The limit plate 16 positions the sliding frame 11, thereby positioning the arc-shaped clamping plate 13.

[0042] The sliding frame 11 has a through hole, and the bottom end of the connecting rod 10 is slidably disposed in the corresponding through hole. When the bottom end of the connecting rod 10 is located in the through hole, the sliding frame 11 can no longer move, thereby fixing the sliding frame 11 on the limiting plate 16. At this time, the arc-shaped clamping plate 13 is located inside the side of the limiting frame 14.

[0043] The second spring 12 is disposed inside the sliding frame 11, and one end of the second spring 12 is fixedly connected to the inner wall of the sliding frame 11.

[0044] Inside the protective frame 3, partitions 17 are fixedly connected between two adjacent limiting frames 14. This ensures that the limiting frame 14 in the middle is located between two adjacent partitions 17, and the limiting frames 14 at both ends are located between the partitions 17 at the ends and the sides of the protective frame 3.

[0045] The other end of the second spring 12 located at both ends is fixedly connected to the inner wall of the protective frame 3, and the other end of the remaining second spring 12 is fixedly connected to one side of an adjacent partition 17. In the initial state, the second spring 12 pushes the sliding frame 11 to move inward toward the limiting frame 14, causing the arc-shaped clamp 13 to move inward toward the limiting frame 14.

[0046] Each sliding frame 11 has a lever 15 fixedly connected to its bottom at the end furthest from the curved clamp 13. This allows the sliding frame 11 to be moved via the lever 15.

[0047] Two limiting plates 16 located at the same limiting frame 14 have rotating shafts 6 rotatably connected to their bottom ends on the side closest to each other. Each rotating shaft 6 is fixedly fitted with a protective plate 5, which is located below the limiting frame 14. When both protective plates 5 are in a horizontal state, their ends contact each other, thereby sealing the bottom of the limiting frame 14.

[0048] A protrusion is fixedly installed directly below each rotating shaft 6, and the protrusion is fixedly connected to the inner wall of the protective frame 3. The protective plate 5 is movably installed on the top of the corresponding protrusion. The protrusion supports and positions the protective plate 5, so that when the protective plate 5 is in a horizontal state, it will be located on the top of the protrusion.

[0049] Working principle:

[0050] When connecting the junction box 2 to the main body 1 of the electricity meter, cut off a section of the insulation layer at one end of the wire to expose the wire core inside. Then straighten one end of the wire.

[0051] Push the two protective plates 5 upwards to rotate them upwards. Insert the wire between the two protective plates 5, allowing the wire core to pass through the limiting frame 14 and enter the wiring hole 7.

[0052] As the wire continues to move upward, its core inserts into the sliding ring 8. The insulation layer on the wire is then blocked by the bottom surface of the sliding ring 8. As the wire continues to move upward, the insulation layer causes the sliding ring 8 to move upward as well.

[0053] The sliding ring 8 slides upward inside the wiring hole 7, which will compress the first spring 9.

[0054] The sliding ring 8 drives the connecting rod 10 to move upward, and the bottom end of the connecting rod 10 will slide out of the through hole on the sliding frame 11. At this time, the second spring 12 will push the sliding frame 11 to slide into the limit frame 14.

[0055] The sliding frame 11 slides on the limiting plate 16, pushing the arc-shaped clamping plate 13 towards the inside of the limiting frame 14, while simultaneously moving the lever 15. This brings the two arc-shaped clamping plates 13 on the limiting frame 14 closer together until they abut against the wire, thus securing the wire. Then, the fastening bolt 4 is rotated to secure the wire and complete the wiring.

[0056] When disassembling the wire, manually move the lever 15 to the side away from the limit frame 14. The lever 15 moves the sliding frame 11 and the arc-shaped clamp 13, causing the arc-shaped clamp 13 to move away from the wire, thus allowing the wire to be removed.

[0057] The sliding frame 11 moves at the bottom of the connecting rod 10. When the through hole moves to the bottom of the connecting rod 10, the first spring 9 pushes the sliding ring 8 downward, causing the inclined end of the connecting rod 10 to gradually move into the through hole. When the end sliding frame 11 moves to one side of the inner wall of the protective frame 3, the middle sliding frame 11 moves to one side of the partition 17, and the bottom end of the connecting rod 10 moves into the corresponding through hole, thereby fixing the sliding frame 11 to the limiting plate 16.

[0058] When not connected to the wiring, the protective plate 5 will rotate to a horizontal position to seal the bottom of the limit frame 14 and reduce the entry of dust.

[0059] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
