Description

Technical Field

[0001] This utility model relates to the field of electricity meter technology, specifically to an electricity meter with fast cable management. Background Technology

[0002] An electricity meter is an instrument used to measure electrical energy; it is also called a kilowatt-hour meter, a power meter, or a kilowatt-hour meter. It refers to instruments that measure various electrical quantities. When using an electricity meter, it is important to note that under low voltage and low current conditions, the meter can be directly connected to the circuit for measurement.

[0003] Patent CN221572660U discloses a power meter for quick cable management. It includes a power meter body, a cover plate rotatably connected to the surface of the power meter body, and a lever fixedly installed on the surface of the cover plate. This device can open the cover plate from the surface of the power meter so that personnel can quickly approach the cable connection position, improve the efficiency of cable installation, and facilitate cable routing to avoid incorrect cable connector connection.

[0004] However, the size of the sleeve in this device is fixed. This means that if the sleeve is compatible with the cable size, the friction will easily cause the cable to rotate and twist when the sleeve is on the cable surface, affecting the connection. If the sleeve is too large, the cable will wobble inside the sleeve, which is not only difficult to protect the cable effectively, but will still affect the connection. To address this, a fast cable management energy meter is proposed to solve the problem that existing energy meters cannot guarantee the stability of the cable after connection. Utility Model Content

[0014] (III) Beneficial Effects

[0015] 1. This quick-connecting electricity meter, after wiring is completed, uses a tool to rotate the long-neck bolt, thereby moving the limiting seat inside the fixed housing out and towards the wire. Depending on the thickness of the wire, the wire is initially clamped and limited by the wire clamping groove. Then, through the limiting plate in the limiting groove, the T-shaped plate moves into the wire clamping groove, thereby pressing and limiting the wire in the wire clamping groove. Finally, the bolt is tightened to fix the position of the T-shaped plate, which solves the problem that existing electricity meters cannot guarantee the stability of the cable after wiring.

[0016] 2. In this quick-wiring energy meter, during wiring, the L-shaped control board drives the movable block in the movable slot to move upward, thereby moving the locking block out of the slot. After the cover is flipped over, the cover is self-limited by friction, which facilitates quick wiring. After the wiring is completed, the cover is reset. During the process, with the help of chamfering, the locking block moves into the movable slot to compress the spring until the locking block enters the slot by the spring force, which can fix the position of the cover and improve the convenience of wiring this energy meter.

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.

[0023] Example: Please refer to Figure 1-4A fast-cable power meter includes a power meter 1, with fixed lugs 2 fixedly connected to both ends of the power meter 1. A groove 3 is provided on one side of the power meter 1, and a cover 4 is rotatably connected to the inner cavity of the groove 3. The cover 4 is connected to the power meter 1 through a connecting mechanism 5. A terminal block 6 is provided in the inner cavity of the groove 3. A wiring hole 7 is provided through the bottom of the power meter 1. A fixed shell 8 is fixedly connected to the bottom of the power meter 1. A limit seat 9 is slidably provided in the inner cavity of the fixed shell 8. A wire-locking groove 10 with decreasing size is provided on one side of the limit seat 9. A long-neck bolt 12 is rotatably connected through the inside of the fixed shell 8. A T-shaped plate 13 is slidably provided on one side of the fixed shell 8. A limit groove 14 is symmetrically provided on the side of the fixed shell 8 facing the T-shaped plate 13. A limit plate 15 is slidably provided in the inner cavity of the limit groove 14. Bolts 16 are provided at both ends of the fixed shell 8. A protective coil 18 is provided in the inner cavity of the wiring hole 7.

[0024] Furthermore, the intersection of the long neck bolt 12 and the fixed shell 8 is limited by a bearing and the two are rotatably connected. The long neck bolt 12 passes through the limiting seat 9 and the two are threadedly connected. The bearing enables the long neck bolt 12 to rotate in the same position, thereby driving the limiting seat 9 to move.

[0025] Furthermore, one side of the limiting plate 15 is fixedly connected to the T-shaped plate 13, and the bolt 16 passes through the fixing shell 8 to the inner cavity of the limiting groove 14 and the two are threadedly connected. After the position of the limiting plate 15 is adjusted by the bolt 16 screwed to the fixing shell 8, the T-shaped plate 13 is pressed and positioned to press and limit the wire in the wire clamping groove 10.

[0026] Furthermore, the connecting mechanism 5 includes a symmetrically opened moving groove 501 at the bottom of the cover 4, a spring 502 is provided in the inner cavity of the moving groove 501, a locking block 503 is fixedly connected to the bottom of the spring 502, a chamfer 504 is provided on one side of the bottom of the locking block 503, and a locking groove 505 adapted to the locking block 503 is symmetrically opened at the bottom of the groove 3, and there is a frictional force between the cover 4 and the groove 3 that can keep the cover 4 stationary.

[0027] Furthermore, a movable groove 506 is symmetrically provided on one side of the cover 4. A movable block 507 is slidably arranged in the inner cavity of the movable groove 506. The movable block 507 is fixedly connected to the locking block 503. An L-shaped control plate 508 is fixedly connected to one end of the movable block 507. The L-shaped control plate 508 blocks the movable groove 506 and is slidably connected to the cover 4. When wiring is required, the movable block 507 in the movable groove 506 is moved upward by the L-shaped control plate 508, thereby moving the locking block 503 out of the locking slot 505. After the cover 4 is flipped over, the cover 4 is self-limited by friction, which facilitates quick wiring. After the wiring is completed, the cover 4 is reset. During the process, with the help of the chamfer 504, the locking block 503 moves into the movable groove 501 to compress the spring 502 until the spring force of the spring 502 causes the locking block 503 to enter the locking slot 505, thus fixing the position of the cover 4 and improving the convenience of wiring this energy meter.

[0028] Furthermore, the inner cavity of the wire clamping groove 10 is provided with a first rubber pad 11, and the T-shaped plate 13 has an arc-shaped groove on the side facing the wire clamping groove 10, and a second rubber pad 17 is provided in the inner cavity of the arc-shaped groove. The first rubber pad 11 and the second rubber pad 17 are used to avoid hard contact between the wire and the wire clamping groove 10 and the T-shaped plate 13, and the stability of the wire after being clamped and limited is improved by forming a squeezing force.

[0029] Working principle: When using this quick-connecting electricity meter, after installing the electricity meter 1 in the required position through the fixing ear 2, the wire is passed through the wiring hole 7 into the groove 3 and connected to the electricity meter 1 with the wiring terminal 6. Then, the long neck bolt 12 is rotated by the tool, which moves the limiting seat 9 in the fixing shell 8 out and moves it towards the wire. According to the thickness of the wire, the wire is initially locked and limited by the wire clamping groove 10. Then, the T-shaped plate 13 is moved into the wire clamping groove 10 through the limiting plate 15 in the limiting groove 14, which presses and limits the wire in the wire clamping groove 10. Finally, the bolt 16 is tightened to fix the position of the T-shaped plate 13. This solves the problem that existing electricity meters cannot guarantee the stability of the cable after wiring.
