Description

Technical Field

[0001] This utility model relates to the field of power meter technology, and in particular to a power meter with stable wiring. Background Technology

[0002] As the core tool for accurate measurement of power parameters and the key carrier for comprehensive monitoring and in-depth analysis of power quality, power meters are used in various scenarios, including parameter acquisition of power control systems, energy consumption metering of energy management systems, signal monitoring of substation automation upgrades, load supervision of residential power monitoring networks, electrical control of industrial automation processes, energy optimization of intelligent building integrated systems, and real-time status feedback of intelligent distribution cabinets and switchgear. They have become an indispensable component for the efficient operation of power systems.

[0003] The existing patent (publication number: CN220289684U) discloses "This utility model discloses a power meter with stable wiring, including: a main body, a shock-absorbing mounting mechanism, and a clamping mechanism. The main body includes a meter body, with a vertical groove on the rear side of the meter body. The wiring hole of the meter body is located at the bottom. The shock-absorbing mounting mechanism includes a slider, a shock-absorbing spring, and a mounting bracket. The mounting bracket is detachably connected to the rear side of the slider. The clamping mechanism includes a primary clamping plate, a threaded slide cylinder, and a movable clamping assembly. Its beneficial effects are: by setting a shock-absorbing mounting mechanism, when the connecting wire pulls the meter body due to factors such as equipment vibration, the device can buffer the pulling force through two sets of shock-absorbing springs to prevent the connecting wire from falling off. At the same time, by setting a clamping mechanism, the connecting wire is further clamped. The protruding teeth on the primary and secondary clamping plates squeeze the wire sheath of the connecting wire to form an uneven surface, which can further prevent the connecting wire from loosening and falling off due to factors such as vibration and temperature changes."

[0004] In the process of developing this application, the inventors discovered the following problems with the prior art: the power meter uses two sets of shock-absorbing springs to buffer the pulling force, but lacks a damping energy-dissipating structure, resulting in poor shock absorption. Furthermore, the convex teeth on the primary and secondary clamping plates squeeze the wire sheath of the connecting wire to form an uneven surface, which clamps the connecting wire. When connecting wires of different diameters, the clamping force cannot be adjusted adaptively. Wires with larger diameters will be excessively squeezed, causing the insulation layer to deform or even crack, while wires with smaller diameters may not be clamped sufficiently, posing a risk of loosening.

[0005] Therefore, those skilled in the art have provided a power meter with stable wiring to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a power meter with stable wiring. By rotating the connecting ring, the slider slides inside the inclined groove, causing the moving block to drive the clamping block to move relative to each other, thereby clamping wires of different diameters. When the wire is pulled, the trapezoidal block will push the inclined block to move, causing the rotating block to pull or push the damper, thereby achieving shock absorption and protection for the instrument body and the wire.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A power meter with stable wiring includes a mounting plate. Damperes are fixedly installed at both the upper and lower ends inside the mounting plate. Two rotating blocks are hinged to each of the two dampers on opposite sides. An inclined block is hinged to the lower end of each of the four rotating blocks. A fixing block is fixedly installed at the rear end of each of the four inclined blocks. A spring is fixedly installed between each pair of the four fixing blocks. A connecting plate is slidably installed at the front end of the mounting plate. Trapezoidal blocks are fixedly installed at the rear ends of both the upper and lower ends of the connecting plate.

[0009] The connecting plate has multiple clamping mechanisms at its lower front end. Each clamping mechanism includes a connecting sleeve. A connecting ring is threaded to the upper outer end of the connecting sleeve. A rotating ring is rotatably mounted at the lower end of the connecting ring. Multiple sliders are fixedly mounted at the lower end of the rotating ring. Multiple clamping blocks are slidably mounted inside the lower end of the connecting sleeve. Each of the multiple clamping blocks has a moving block fixedly mounted on opposite sides of each pair of opposite sides. Each of the multiple moving blocks has two inclined grooves inside.

[0010] Furthermore, the lower ends of each pair of inclined blocks are inclined, and the upper ends of both sides of the two trapezoidal blocks are inclined.

[0011] Furthermore, the external parts of the multiple fixed blocks are slidably disposed inside the rear end of the mounting plate, and the lower ends of the multiple inclined blocks are respectively slidably disposed on the upper ends of the opposite sides of the two trapezoidal blocks.

[0012] Furthermore, the external parts of the plurality of inclined blocks are slidably disposed inside the rear end of the mounting plate, and the external parts of the two trapezoidal blocks are slidably disposed inside the mounting plate.

[0013] Furthermore, the lower ends of the multiple sliders are respectively slidably disposed on opposite sides of the multiple inclined slots, the upper ends of the multiple moving blocks are all parallel to the lower end of the rotating ring, and the instrument body is fixedly disposed at the front end of the connecting plate.

[0014] Furthermore, the rotating ring is slidably disposed on the lower part of the outer side of the connecting sleeve, and the multiple clamping blocks are all arc-shaped on opposite sides of each other. The rear end of the connecting sleeve is fixedly disposed on the lower part of the front end of the connecting plate.

[0015] Furthermore, each of the plurality of clamping blocks is fixedly provided with an insulating rubber pad on each opposite side, and each of the plurality of insulating rubber pads is fixedly provided with a diamond-shaped anti-slip pattern on each opposite side.

[0016] This utility model has the following beneficial effects:

[0017] 1. The present invention proposes a power meter with stable wiring. When the conductor is pulled by an external force, causing the meter to vibrate, the inclined surface of the trapezoidal block will apply a pushing force to the inclined block, forcing the inclined block and the fixed block to slide in opposite or relative straight lines inside the mounting plate, thereby stretching or compressing the spring. At the same time, the rotating block rotates, driving the damper to extend and retract. The extension and retraction of the damper can effectively suppress the movement speed of the inclined block and the fixed block, thereby slowing down the instantaneous transmission of vibration or pulling force, improving vibration resistance and pulling force, and thus achieving protection for the meter body and conductor.

[0018] 2. The present invention proposes a power meter with stable wiring. When fixing wires of different diameters, the operator manually rotates the connecting ring, causing the connecting ring and the rotating ring to move downward along the connecting sleeve axis. This causes the lower end of the slider to slide in the inclined groove inside the moving block, which in turn pushes the clamping blocks to slide in a straight line relative to each other inside the connecting sleeve. This causes the arc-shaped clamping blocks to gradually converge, thus forming a clamp for wires of different diameters. It has strong compatibility. Under the action of clamping force, the rubber pad deforms and tightly wraps the outer surface of the wire, further improving the clamping stability. This enhances the anti-pull-out and anti-slip effects, effectively preventing the wire from loosening, displacing, or even falling off due to external pulling or vibration.

[0027] 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.

[0028] Reference Figures 1-4 One embodiment provided by this utility model:

[0029] A power meter with stable wiring includes a mounting plate 1. Damperes 5 are fixedly installed at both the upper and lower ends inside the mounting plate 1. Two rotating blocks 6 are hinged to each other on the opposite side of the two dampers 5. Inclined blocks 7 are hinged to the lower ends of the four rotating blocks 6. Fixed blocks 8 are fixedly installed at the rear ends of the four inclined blocks 7. Springs 9 are fixedly installed between each pair of the four fixed blocks 8. A connecting plate 2 is slidably installed at the front end of the mounting plate 1. Trapezoidal blocks 10 are fixedly installed at the rear ends of both the upper and lower ends of the connecting plate 2.

[0030] Multiple inclined blocks 7 are inclined at the lower end of each pair of opposite sides, and the upper ends of both sides of the two trapezoidal blocks 10 are inclined. Multiple fixed blocks 8 are slidably disposed inside the rear end of the mounting plate 1. Multiple inclined blocks 7 are slidably disposed at the upper end of the opposite side of the two trapezoidal blocks 10 at the lower end of each pair of opposite sides. Multiple inclined blocks 7 are slidably disposed inside the rear end of the mounting plate 1. The two trapezoidal blocks 10 are slidably disposed inside the mounting plate 1.

[0031] Specifically, when the instrument body 3 can be fixed to the power distribution cabinet, switch cabinet or other carrier by the mounting plate 1, if the wire at the lower end of the instrument body 3 is pulled, the connecting plate 2 will drive the instrument body 3 to slide up and down along the front end of the mounting plate 1. When the connecting plate 2 slides up and down with vibration, the trapezoidal block 10 fixed at its upper and lower ends will slide synchronously. Since the two sides of the trapezoidal block 10 are inclined surfaces and are completely in contact with the inclined surface at the lower end of the inclined block 7, the sliding of the trapezoidal block 10 will generate a pushing force on the inclined block 7, pushing the inclined block 7 to move in opposite or relative straight lines along the inside of the mounting plate 1.

[0032] When the inclined block 7 moves inside the mounting plate 1, it will synchronously drive the fixed block 8, which is fixedly connected at the rear end, to slide along the internal groove of the mounting plate 1. During the sliding process of the fixed block 8, it will stretch or compress the springs 9 that are opposite each other, causing the springs 9 to deform. At the same time, the rotating block 6 hinged at the upper end of the inclined block 7 will rotate synchronously with the movement of the inclined block 7, thereby pushing or pulling the damper 5 to extend or retract. The damper 5 reduces the sliding speed of the inclined block 7 and the fixed block 8 through the viscous resistance of the internal damping medium, thereby achieving the protection of the instrument body 3 and the wires.

[0033] After the external vibration or pulling ends, the spring 9 rebounds and pushes the fixed block 8 and the inclined block 7 to return to their original position along the internal slide groove of the mounting plate 1. During the reset process, the inclined surface at the lower end of the inclined block 7 will generate a reverse thrust on the trapezoidal block 10, so that the trapezoidal block 10 and the connecting plate 2 return to their initial position, ensuring that the instrument body 3 is always in the preset installation position.

[0034] It should be noted that the mounting plate 1 has a T-shaped groove at its front end, and the connecting plate 2 has a T-shaped block fixedly installed at its rear end. Two trapezoidal blocks 10 are fixedly installed at the upper and lower ends of the T-shaped block. The connecting plate 2 is slidably installed at the front end of the mounting plate 1 through the T-shaped block and the T-shaped slide. The springs 9 are all made of stainless steel, which has good fatigue resistance and can avoid rust affecting the elasticity. At the same time, it has good resilience and can quickly realize the component reset. The damper 5 is a mature and publicly available technology. Therefore, its specific structure, model and working principle will not be described in detail in this article. The mounting plate 1 has mounting holes at all four corners. The mounting plate 1 can be fixed to the power distribution cabinet, switch cabinet or other mounting carrier by bolts passing through the mounting holes. The mounting holes are equipped with anti-slip washers to prevent the bolts from loosening and ensure that the mounting plate 1 is firmly fixed. The mounting plate 1 is made of steel plate and its surface is hot-dip galvanized. The hot-dip galvanized layer can effectively isolate air and moisture and prevent the mounting plate 1 from rusting and corroding.

[0035] Reference Figures 1-6 Multiple clamping mechanisms 4 are provided at the lower end of the front end of the connecting plate 2. Each clamping mechanism 4 includes a connecting sleeve 401. A connecting ring 402 is threadedly connected to the upper end of the connecting sleeve 401. A rotating ring 403 is rotatably provided at the lower end of the connecting ring 402. Multiple sliders 404 are fixedly provided at the lower end of the rotating ring 403. Multiple clamping blocks 406 are slidably provided at the lower end of the connecting sleeve 401. Each pair of opposite sides of the multiple clamping blocks 406 is fixedly provided with a moving block 405. Each of the multiple moving blocks 405 has two inclined grooves 407 inside.

[0036] Multiple sliders 404 are slidably mounted on opposite sides of multiple inclined grooves 407 at their lower ends. Multiple moving blocks 405 are parallel to each other at the lower end of the rotating ring 403 at their upper ends. The instrument body 3 is fixedly mounted at the front end of the connecting plate 2. The rotating ring 403 is slidably mounted on the lower end of the connecting sleeve 401 at its inner end. Multiple clamping blocks 406 are arc-shaped on opposite sides of each other. The rear end of the connecting sleeve 401 is fixedly mounted on the lower end of the front end of the connecting plate 2. Insulating rubber pads are fixedly mounted on opposite sides of each pair of clamping blocks 406. Diamond-shaped anti-slip patterns are fixedly mounted on opposite sides of each pair of insulating rubber pads.

[0037] Specifically, in the wire connection operation, the wire must first be passed through the connecting sleeve 401 of the clamping mechanism 4 and the conductive connection with the instrument body 3 is completed. Then the operator manually rotates the connecting ring 402. Since the connecting ring 402 and the connecting sleeve 401 are connected by threads, when the connecting ring 402 rotates, it will move smoothly downward along the axis of the connecting sleeve 401. At the same time, it will drive the rotating ring 403 connected at the lower end to move downward synchronously. The rotating ring 403 and the connecting ring 402 are connected by a bearing to ensure that the rotating ring 403 only moves axially when the connecting ring 402 rotates. When the rotating ring 403 moves downward, the sliders 404 evenly distributed at its lower end will move downward synchronously. Since the lower end of the slider 404 slides into the inclined groove 407 of the moving block 405, the vertical downward movement of the slider 404 will push the moving block 405, so that the moving blocks 405 move relative to each other in the lower end inside the connecting sleeve 401. When the moving blocks 405 move, they will drive the clamping blocks 406 fixedly connected to them to converge towards the center synchronously, forming a multi-directional wrapping force on the wire.

[0038] As the clamping block 406 moves toward the center, its inner arc-shaped surface will fit tightly against the surface of the conductor. By increasing the contact area, the clamping force is dispersed, avoiding excessive local pressure that could damage the conductor. At the same time, the insulating rubber pad on the inner side of the clamping block 406 is made of nitrile rubber, which is oil-resistant and temperature-resistant. It will undergo elastic deformation due to the compression of the conductor, thus completely wrapping the surface of the conductor. The diamond-shaped anti-slip texture on the surface of the rubber pad will be embedded into the surface of the conductor insulation layer and form a physical interlock, thereby effectively preventing the conductor from slipping or shifting due to pulling or vibration, thus ensuring the insulation and anti-slip effect during long-term use.

[0039] It should be noted that the instrument body 3 is a conventional power parameter measuring instrument. Its core function is to collect and monitor the power parameters transmitted by the wire. It needs to be connected to an external power circuit through the wire to obtain signals. The instrument body 3 is a device or equipment that exists in the prior art or can be implemented by the prior art. Its function, specific composition and principle are clear to those skilled in the art, so they will not be described in detail. The threaded surface of the connecting sleeve 401 is galvanized or chrome-plated, which is corrosion resistant and can prevent the threads from rusting or jamming due to the humid environment and slightly corrosive gases during long-term use. This ensures that the connecting ring 402 can rotate smoothly, thereby ensuring the long-term stable clamping effect of the clamping mechanism 4 on the wire. The rear end of the instrument body 3 is fixed to the front end of the connecting plate 2 by bolts.

[0040] All standard parts used in this application can be purchased from the market. Special-shaped parts can be customized according to the description and drawings. The specific connection methods of each part adopt mature bolts, rivets, welding and other conventional methods in the prior art. Mechanical parts, components and equipment adopt conventional models in the prior art. The circuit connection between the wires and the instrument body 3 adopts conventional connection methods in the prior art. Therefore, they will not be described in detail. All contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0041] Working principle: When the instrument body 3 is pulled, the connecting plate 2 will drive the instrument body 3 to slide up and down at the front end of the mounting plate 1. When the connecting plate 2 is vibrated and slides up and down, the trapezoidal blocks 10 at its upper and lower ends will slide synchronously. The trapezoidal blocks 10 will squeeze the inclined block 7, causing it to move in opposite directions. When the inclined block 7 moves inside the mounting plate 1, it will drive the fixed block 8 connected to it to slide synchronously along the slide groove inside the mounting plate 1, and stretch or compress the spring 9, causing the spring 9 to deform. During the movement of the inclined block 7, it will drive the hinged rotating block 6 at its upper end to move synchronously, causing the damper 5 to extend or retract. The damper 5 reduces the sliding speed of the inclined block 7 and the fixed block 8 through the viscous resistance of the internal damping medium, thereby reducing the impact force on the instrument body 3. When the impact force dissipates, the spring 9 rebounds, causing the inclined block 7 and the fixed block 8 to slide back to their original position inside the mounting plate 1. The reset of the inclined block 7 will push the trapezoidal block 10 to reset, so that the connecting plate 2 is in its initial position.

[0042] During wiring, the wire is first passed through the connecting sleeve 401, and then the wire is connected to the instrument body 3. When fixing the wire, the operator rotates the corresponding connecting ring 402, which moves downward along the axis of the connecting sleeve 401, and drives the lower rotating ring 403 to move downward synchronously. When the rotating ring 403 moves downward, the slider 404 at its lower end moves downward synchronously, which pushes the moving blocks 405 to move relative to each other in pairs inside the connecting sleeve 401. This causes multiple moving blocks 405 to drive the clamping blocks 406 connected to them to converge towards the center. When the clamping blocks 406 move towards the center, their arc-shaped inner side will fit tightly against the surface of the wire to adapt to wires of different diameters. At the same time, the insulating rubber pad on the inner side of the clamping block 406 wraps the wire through elastic deformation. The diamond-shaped anti-slip texture on the surface of the rubber pad is embedded in the wire insulation layer to form a bite, thereby effectively preventing the wire from slipping.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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.
