Description

Technical Field

[0001] This utility model relates to the field of electricity meter technology, specifically to an anti-static electricity meter. Background Technology

[0002] As a key device in the power system for measuring electricity consumption, electricity meters are widely used in various scenarios such as industrial production, residential buildings, commercial sites, and public infrastructure. Their operational stability and metering accuracy directly affect the rational allocation and settlement of electricity resources. During daily operation, electricity meters are susceptible to static electricity generation on their outer casing, internal electronic components, and terminals due to environmental factors such as friction from objects, changes in air humidity, and charge transfer. If this static electricity is not effectively dissipated in a timely manner, it may not only interfere with the sensitive electronic components inside the meter but may also gradually accumulate to form a high potential, causing irreversible damage to the components and affecting the normal operation and lifespan of the meter. Therefore, anti-static design for electricity meters has become an important part of the research and development and production process.

[0003] Existing anti-static solutions for electricity meters have significant shortcomings in terms of static electricity conduction and grounding structure design. Regarding static electricity conduction, most solutions use only a single grounding path, dissipating static electricity only from a specific part of the meter. This fails to comprehensively cover multiple critical areas prone to static electricity generation, such as the casing, internal components, and wiring terminals. Consequently, static electricity easily accumulates in uncovered areas, leading to metering accuracy deviations and even damage to internal components, affecting overall operational stability. In terms of grounding component installation, existing electricity meters mostly use fixed connections for their grounding components. This prevents flexible adjustment based on the surface position and distance of the grounding object in the actual installation scenario. This makes it difficult to quickly and accurately align the grounding component with the grounding object, increasing the complexity of the installation process and prolonging installation time. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an anti-static energy meter to solve the problem mentioned in the background art, which is that static electricity tends to accumulate in uncovered areas, leading to deviations in the metering accuracy, damage to internal components, impact on overall operational stability, increased complexity of installation, and extended installation time.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-static energy meter, comprising:

[0006] An electricity meter housing, on the surface of which a display unit is mounted, and on the surface of which wiring terminals are mounted;

[0007] A connecting plate is disposed at the bottom of the outer casing of the electricity meter. A grounding frame is installed at the bottom of the connecting plate. A grounding rod is inserted into the inner cavity of the grounding frame. A grounding foot is installed on the surface of the grounding rod. A first grounding body is installed on the surface of the grounding foot.

[0008] A connector is located at the bottom of the connecting plate. A guide rod is installed on the surface of the connector via a grounding wire. A guide cylinder is installed on the surface of the first grounding body. The guide rod is inserted into the interior of the guide cylinder. A spring is installed on the guide rod and the inner wall of the guide cylinder.

[0009] A conductive head is disposed on the surface of the electricity meter casing. A conductive ring is installed on the surface of the conductive head, and a second grounding body is installed on the surface of the conductive ring through a grounding wire.

[0010] Preferably, a first threaded rod is screwed onto the surface of the second grounding body, and a nut is screwed onto the surface of the conductive head. The first threaded rod is used to fix the second grounding body, and the nut can stably install the conductive ring onto the surface of the conductive head.

[0011] Preferably, bolts are screwed onto the four bottom corners of the connecting plate. The bolts penetrate the connecting plate and are screwed onto the bottom of the electricity meter casing. The bolts can install the connecting plate onto the bottom of the electricity meter casing and connect the connecting plate to the internal metering components of the electricity meter.

[0012] Preferably, a second threaded rod is screwed onto the surface of the grounding foot. The second threaded rod passes through the surface of both the grounding foot and the first grounding body. The grounding foot and the first grounding body can be connected through the second threaded rod, and the first grounding body can be installed on the ground or other grounded object surface.

[0013] Preferably, the upper surface of the connector is provided with a positioning clamp, and a connecting block is installed at the connection point of the positioning clamp. A connecting seat is installed at the connection point of the connector. The positioning clamp can be used to install the connector on the protruding surface of the terminal block.

[0014] Preferably, each of the connecting blocks has a plug rod installed at its bottom, and each of the connecting seats has a plug hole on its upper surface. The plug rod is inserted into the plug hole, which can improve the connection stability between the connector and the positioning hoop.

[0015] Preferably, the surface of the plug rod is evenly provided with anti-slip protrusions, and the inner wall of the plug hole is evenly provided with anti-slip grooves. The anti-slip protrusions are elastically designed and penetrate deep into the anti-slip grooves, which can ensure the stability of the plug rod after insertion.

[0016] Preferably, the surface of the guide rod is equipped with a guide strip, and the surface of the guide cylinder is provided with a guide groove. The width of the guide groove is adapted to the width of the guide strip, which can ensure that the guide rod slides smoothly in the guide cylinder.

[0017] Compared with the prior art, this utility model provides an anti-static energy meter, which has the following beneficial effects:

[0018] This anti-static energy meter connects the conductive ring and the second grounding body via a grounding wire. This allows for the timely conduction of static electricity generated on the surface of the energy meter casing to the second grounding body, preventing the accumulation of static electricity on the casing surface and its impact on the meter's operation. The grounding foot connects to the first grounding body, guiding static electricity generated inside the energy meter to the first grounding body, achieving multi-path conduction of static electricity. The connecting rod and connecting cylinder connect to the second grounding body, enabling path conduction of static electricity at the terminals. Through the synergistic effect of the second and first grounding bodies, the anti-static performance of the energy meter is effectively enhanced, ensuring that internal components are not damaged by static electricity and maintaining the stability of the energy meter's measurement and operation.

[0019] The added grounding rod is installed in the inner cavity of the grounding frame by insertion. By moving the grounding rod, the grounding foot and the first grounding body can be quickly adjusted to the position of contact with the surface of the grounding object. This allows the position of the first grounding body to be adjusted according to the distance from the surface of the grounding object, achieving rapid alignment of the grounding components. The connecting cylinder moves with the first grounding body, and the connecting rod is pulled by the spring, which is transmitted to the connected grounding wire, causing the grounding wire to make tight contact with the surface of the energy meter casing. This prevents the grounding wire from falling apart and allows for the tidying up of the grounding wire, thus eliminating the need for complicated procedures and greatly improving the ease of installation.

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] This utility model provides a technical solution: an anti-static energy meter. Please refer to [link / reference]. Figure 1 It includes an electricity meter housing 1, a display unit 101 mounted on the surface of the electricity meter housing 1, and a wiring terminal 102 mounted on the surface of the electricity meter housing 1;

[0031] Connector 6 is located at the bottom of connector plate 2. Please refer to [link / reference]. Figure 5 A guide rod 7 is mounted on the surface of connector 6 via a grounding wire, and a guide cylinder 8 is mounted on the surface of the first grounding body 5. The guide rod 7 is inserted into the interior of the guide cylinder 8. Please refer to [link / reference].

[0032] Please see Figure 1 The conductive head 10 is disposed on the surface of the electricity meter casing 1. Please refer to [link / reference]. Figure 2 A conductive ring 11 is mounted on the surface of the conductive head 10, and a second grounding body 12 is mounted on the surface of the conductive ring 11 through a grounding wire.

[0033] The conductive head 10 on the surface of the electricity meter casing 1 is connected to the second grounding body 12 through the conductive ring 11 on its surface by means of a grounding wire. This can promptly conduct the static electricity generated on the surface of the electricity meter casing 1 to the second grounding body 12, thus preventing the accumulation of static electricity on the surface of the electricity meter casing 1 and its impact on the use of the electricity meter.

[0034] The connecting plate 2 is connected to the internal metering components of the energy meter. A grounding rod 4 is inserted into the grounding frame 3 at the bottom of the connecting plate 2. The grounding rod 4 is connected to the first grounding body 5 through the grounding foot 41 on the surface, which can guide the static electricity generated inside the energy meter to the first grounding body 5, realizing the multi-path conduction of static electricity.

[0035] Meanwhile, the connector 6 at the bottom of the connecting plate 2 is connected to the second grounding body 12 through the guide rod 7 and the guide cylinder 8, so as to realize the path conduction of static electricity in the terminal 102. Through the synergistic effect of the second grounding body 12 and the first grounding body 5, the anti-static effect of the energy meter is effectively improved, ensuring that the internal components of the energy meter are not damaged by static electricity, and maintaining the stability of the energy meter's measurement and operation.

[0036] The grounding rod 4 is installed in the inner cavity of the grounding frame 3 by insertion. During installation, no complicated tools are needed. Simply moving the grounding rod 4 can quickly adjust the grounding foot 41 and the first grounding body 5 to the position of contact with the surface of the grounding object. This allows the position of the first grounding body 5 to be adjusted according to the distance from the surface of the grounding object, achieving rapid alignment of the grounding components. The guide tube 8 then moves the guide rod 7 inserted inside it. Since the guide rod 7 and the inner wall of the guide tube 8 are equipped with springs 9, the springs 9 will generate tension on the guide rod 7 during the movement of the guide rod 7.

[0041] Please see Figure 7 Each connecting block 18 has a plug rod 20 installed at its bottom, and each connecting seat 19 has a plug hole 21 on its upper surface. The plug rod 20 is inserted into the plug hole 21, which can improve the connection stability between the connector 6 and the positioning clamp 17.

[0042] The surface of the plug rod 20 is evenly provided with anti-slip protrusions 22, and the inner wall of the plug hole 21 is evenly provided with anti-slip grooves 23. The anti-slip protrusions 22 are elastically designed and penetrate deep into the anti-slip grooves 23, which can ensure the stability of the plug rod 20 after insertion.

[0043] Please see Figure 5 The guide rod 7 has a guide strip 24 mounted on its surface. Please refer to [link / reference].
