Description

Technical Field

[0001] This application belongs to the field of electrical control fixture technology, and relates to a side-pressure type electrical control fixture and an electric meter power-on device. Background Technology

[0002] In existing technologies, the first-generation meter power-on method directly connects the calibration platform and the meter's power supply column using multiple exposed power cables. This exposed power cable poses a risk of electric shock and can easily cause injury to operators. Furthermore, it requires repeated tightening and loosening of the exposed power cable, leading to loosening at connection points, complex operation, and significant waste of manpower and resources. The second-generation meter power-on method uses a rigid contact design between a metal limiting post and the socket. This reduces the risk of electric shock for operators and the complexity of frequent tightening and loosening of the power cable. However, because the meter's power supply column needs to be in close contact with the restrictive socket's space, friction occurs between the column and the space during insertion and removal, damaging the nickel plating on the column's surface and affecting the meter's lifespan. Additionally, the irregular, uneven surface of the power supply column makes insertion and removal difficult, resulting in wasted manpower and increased time costs. The third-generation electricity meter adopts a modular design for power supply, combining the size of the storage space. Each storage space can be finely adjusted in practice to ensure a tight contact between the power supply column behind the meter and the storage space. However, due to the modular design, continuous insertion and removal vibration during use may cause the module to shift, resulting in abnormal alarms on the calibration platform and reducing production efficiency. At the same time, modules that become loose due to frequent insertion and removal vibration need to be replaced periodically, increasing tooling costs. Summary of the Invention

[0033] The following specific examples illustrate the implementation of this application. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. This application can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this application. It should be noted that, unless otherwise specified, the following embodiments and features in the embodiments can be combined with each other.

[0034] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this application. Therefore, the drawings only show the components related to this application and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0035] like Figures 1-3 A side-pressure type electrical fixture is shown, comprising: a base 1, on which an adjustment structure 2 and a movable plate 3 are provided. The movable plate 3 is movably disposed on the base 1 and has at least one limiting insertion hole 31. A first conductive part 11 is fixed on the base 1 and is located within the limiting insertion hole 31. A second conductive part 311 is provided on the inner wall of the limiting insertion hole 31, and a receiving space 4 for accommodating a power supply post (not shown) is formed between the second conductive part 311 and the first conductive part 11. The adjustment structure 2 is used to drive the movable plate 3 to reciprocate along a first direction to adjust the size of the receiving space 4 in the first direction. Figure 2 As shown, the first direction of this application is along the X-axis of the coordinate system.

[0036] As described above, this application uses the adjusting structure 2 to drive the moving plate 3 to reciprocate along the first direction, which can flexibly adjust the size of the accommodating space 4 in the first direction to increase or decrease, thereby achieving unobstructed insertion and removal of the power supply column and the accommodating space 4. At the same time, the accommodating space 4, whose size is variable along the first direction, can adapt to power supply columns of different thicknesses, increasing the adaptability of the tooling. The unobstructed insertion and removal of the power supply column and the accommodating space 4 in this application has the advantages of reducing power consumption risks and tooling costs, and improving the service life of the electricity meter and the stability of power supply.

[0037] In a specific embodiment, such as Figure 1 and Figure 2 As shown, the adjustment structure 2 includes: an abutment portion 21, such as... Figure 4 As shown, the abutment 21 is fixed on the base 1 and located on one side of the movable plate 3; the elastic member 22 is disposed between the abutment 21 and the movable plate 3; the adjustment component 23 is located on the other side of the movable plate 3; wherein, the adjustment component 23 is used to drive the movable plate 3 to reciprocate along the first direction.

[0038] When the power supply column needs power, it is inserted and the adjusting assembly 23 is rotated. The adjusting assembly 23 drives the moving plate 3 to move the second conductive part 311 along the first direction toward the first conductive part 11. At this time, the size of the accommodating space 4 along the first direction gradually decreases until the second conductive part 311 presses against the power supply column, and the rotation of the adjusting assembly 23 stops. When the power supply column does not need power, the adjusting assembly 23 is rotated again. The adjusting assembly 23 no longer applies a force to the moving plate 3 along the first direction toward the first conductive part 11. At this time, the elastic part... Under the action of elastic deformation, component 22 provides a reaction force to drive the moving plate 3 to move the second conductive part 311 away from the first conductive part 11 along the first direction. The size of the accommodating space 4 gradually increases along the first direction to realize the unobstructed insertion and removal of the power supply column and the accommodating space 4. Therefore, through the linkage relationship between the elastic component 22, the moving plate 3 and the adjusting component 23, this application can flexibly adjust the size of the accommodating space 4 along the first direction to make it larger or smaller, so that the accommodating space 4 can adapt to power supply columns of different thicknesses and realize the unobstructed insertion and removal of the power supply column and the accommodating space 4.

[0039] The unobstructed insertion and removal of the power supply column and the housing space 4 in this application reduces the electrical risks caused by the direct connection of exposed power lines to the power supply column of the meter in related technologies. It avoids the damage to the nickel plating layer on the surface of the power supply column caused by friction between the restrictive socket and the surface of the power supply column during the insertion and removal of the power supply column in related technologies. It also avoids the problem of module loosening caused by frequent insertion and removal of the power supply column in related technologies, which affects the power supply stability of the meter, and avoids the tooling costs caused by regularly replacing loose modules. Therefore, the unobstructed insertion and removal of the power supply column and the housing space 4 in this application not only reduces electrical risks and tooling costs, but also improves the service life of the meter and the power supply stability.

[0040] In one embodiment, such as Figure 1 and Figure 2 As shown, the adjustment assembly 23 includes a first column (not shown) and an adjustment member (not shown). The first column is fixed to the base 1, and the adjustment member is eccentrically pivotally connected to the first column. In this application, the first column is mounted on the base 1 as a fixed support point to limit the movement range of the adjustment member and provide a pivot fulcrum; the adjustment member is eccentrically pivotally connected to the limiting column, and the adjustment member is triggered to rotate eccentrically around the first column by rotation or pressing.

[0041] Furthermore, in one embodiment, such as Figure 1 and Figure 2 As shown, the adjusting component is a hollow cylindrical knob (not shown), and an eccentric cam structure (not shown) is embedded at the end of the hollow cylindrical knob. The eccentric cam structure (not shown) is pivotally connected to the free end of the first column.

[0042] This application allows the adjusting member to be continuously rotated in the same direction, converting the rotational motion of the adjusting member into the linear displacement of the moving plate 3. The adjusting member first approaches the moving plate 3, driving the moving plate 3 to move along the first direction toward the side where the elastic member 22 is located. The elastic member 22 undergoes elastic deformation, and the second conductive part 311 moves with the moving plate 3 toward the side closer to the first conductive part 11. The size of the accommodating space 4 gradually decreases along the first direction, and the second conductive part 311 gradually presses against the power supply column. If the adjusting member continues to rotate, it no longer applies pressure to the moving plate 3 and moves away from the moving plate 3. At this time, the elastic member 22 releases elastic potential energy to provide a force to drive the moving plate 3 to move along the first direction toward the side where the adjusting component 23 is located. At this time, the second conductive part 311 moves with the moving plate 3 away from the first conductive part 11, and the size of the accommodating space 4 gradually increases along the first direction, thereby realizing the unobstructed insertion and removal of the power supply column and the accommodating space 4. Therefore, through the linkage between the elastic component 22, the movable plate 3, and the adjusting component 23, this application can flexibly adjust the size of the accommodating space 4 along the first direction to make it larger or smaller, so that the accommodating space 4 can be adapted to power supply columns of different thicknesses and realize the unobstructed insertion and removal of the power supply column and the accommodating space 4.

[0043] The unobstructed insertion and removal of the power supply column and the housing space 4 in this application reduces the electrical risks caused by the direct connection of exposed power lines to the power supply column of the meter in related technologies. It avoids the damage to the nickel plating layer on the surface of the power supply column caused by friction between the restrictive socket and the surface of the power supply column during the insertion and removal of the power supply column in related technologies. It also avoids the problem of module loosening caused by frequent insertion and removal of the power supply column in related technologies, which affects the power supply stability of the meter, and avoids the tooling costs caused by regularly replacing loose modules. Therefore, the unobstructed insertion and removal of the power supply column and the housing space 4 in this application not only reduces electrical risks and tooling costs, but also improves the service life of the meter and the power supply stability.

[0044] In one embodiment, the adjustment assembly 23 includes a second column (not shown) and an adjustment bolt (not shown). The second column is fixed on the base 1 and has a bolt hole (not shown). The adjustment bolt is threaded to the bolt hole and passes through the bolt hole to abut against the movable plate 3. The adjustment bolt is adjusted so that the adjustment bolt drives the movable plate 3 to reciprocate along a first direction.

[0045] It may also include an anti-loosening component (not shown), which includes a locking nut (not shown) fitted onto the adjusting bolt and pressed against the end face of the second column.

[0046] Possibly, the anti-loosening component includes: a locking washer (not shown) located at the threaded connection between the adjusting bolt and the second column.

[0047] This application allows the adjusting bolt to be turned clockwise, causing it to move closer to the moving plate 3. This moves the moving plate 3 closer to the elastic member 22. Under the force of the moving plate 3, the elastic member 22 undergoes elastic deformation, causing the second conductive part 311 to move closer to the first conductive part 11 along with the moving plate 3. The size of the accommodating space 4 along the first direction decreases, and the second conductive part 311 gradually presses against the power supply post. The adjustment bolt is then stopped. Next, the adjusting bolt is turned counterclockwise. It no longer exerts a force on the moving plate 3 towards the elastic member 22. Simultaneously, under the reaction force of the elastic member 22, the moving plate 3 moves away from the elastic member 22. At this point, the second conductive part 311 moves away from the first conductive part 11 along with the moving plate 3, and the size of the accommodating space 4 along the first direction increases. The adjustment bolt is then turned counterclockwise until the power supply post separates freely from the first conductive part 11 and the second conductive part 311.

[0048] The unobstructed insertion and removal of the power supply column and the housing space 4 in this application reduces the electrical risks caused by the direct connection of exposed power lines to the power supply column of the meter in related technologies. It avoids the damage to the nickel plating layer on the surface of the power supply column caused by friction between the restrictive socket and the surface of the power supply column during the insertion and removal of the power supply column in related technologies. It also avoids the problem of module loosening caused by frequent insertion and removal of the power supply column in related technologies, which affects the power supply stability of the meter, and avoids the tooling costs caused by regularly replacing loose modules. Therefore, the unobstructed insertion and removal of the power supply column and the housing space 4 in this application not only reduces electrical risks and tooling costs, but also improves the service life of the meter and the power supply stability.

[0049] In one embodiment, one or more adjustment components 23 mentioned in any of the above embodiments may be provided.

[0050] In this embodiment, as Figure 1 and Figure 2 As shown, two adjustment components 23 are provided, which are symmetrically arranged on one side of the moving plate 3. The two adjustment components 23 can prevent the moving plate 3 from deviating due to uneven force on the moving plate 3, which in turn causes slight distortion of the shape of the accommodating space 4, reduces the fit between the power supply column and the accommodating space 4, and affects the user experience. Alternatively, uneven contact between the power supply column and the first conductive part 11 and the second conductive part 311 can cause unstable power supply to the meter and affect the user experience.

[0051] In one embodiment, an adjustment component 23 may be provided at the center line of the moving plate 3. Alternatively, multiple adjustment components 23 may be provided. These multiple adjustment components 23 may be evenly arranged on one side of the moving plate 3 or scattered on one side of the moving plate 3. During the adjustment process, the limiting post can maintain linear movement under the condition of ensuring uniform force, thereby improving the compatibility between the accommodating space 4 and the power supply post, or ensuring that the power supply post is in full contact with the first conductive part 11 and the second conductive part 311 to maintain stable power supply to the meter.

[0052] In one embodiment, the elastic component 22 may be one or more. These elastic components 22 may be evenly distributed between the abutment portion 2 and the movable plate 3, or scattered between them. This application prevents the movable plate 3 from deviating from its movement path under the uneven counterforce of the elastic component 22 by providing one or more elastic components 22. This prevents slight distortion of the shape of the receiving space 4, making it difficult to separate the power supply column from the receiving space 4, affecting the user experience, or causing uneven contact between the power supply column and the first conductive part 11 and the second conductive part 311, resulting in unstable power supply to the meter and affecting the user experience.

[0053] In this embodiment, as Figure 1 and Figure 2 As shown, the elastic component 22 can be configured as one, and the elastic component 22 can be disposed on the center line of the moving plate 3. This application provides an elastic component 22 on the center line of the moving plate 3, which not only enables the moving plate 3 to maintain linear motion under the reaction force of the elastic component 22, but also saves costs (i.e., in order to keep the moving plate 3 from shifting position, other elastic components 22 are omitted).

[0054] In one embodiment, the elastic component 22 is a spring, a bellows, or an elastic rubber column. In this application, the elastic component 22 can be a spring. Springs have a simple structure, are easy to manufacture and install, and also have good shock absorption and energy storage functions, allowing for a large number of repeated compressions. In this application, the elastic component 22 can be a bellows. The bellows can absorb axial, lateral, or angular displacement of the pipe through its corrugated structure, providing displacement compensation and effectively preventing the moving plate 3 from deviating from its movement path. In this application, the elastic component 22 can be an elastic rubber column. This elastic rubber column has high flexibility and wear resistance, which can reduce the resistance when the moving plate 3 moves towards the side closer to the elastic component 22, making the rotation adjustment assembly 23 easier to operate.

[0055] In one embodiment, the two ends of the elastic member 22 can be movably or fixedly connected to the abutment part 2 and the movable plate 3, respectively. The connection methods of the two ends of the elastic member 22 include, but are not limited to, movable connection and fixed connection.

[0056] In one embodiment, the receiving space 4 can be cylindrical, prismatic, or elliptical. The different shapes of the receiving spaces 4 provided in this application can accommodate power supply columns of different shapes, increasing the application scenarios of this side-pressure type power supply fixture.

[0057] In one embodiment, a guide structure (not shown) is provided between the movable plate 3 and the base 1. The guide structure includes: a guide rail (not shown) provided on the base 1; and a slider (not shown) provided at the bottom of the movable plate 3, which slides with the guide rail to limit the movement path of the movable plate 3.

[0058] The guide structure may be a ball linear guide or a dovetail guide.

[0059] In one embodiment, the contact surfaces of the first conductive part and the second conductive part can be conductive sheets, arc-shaped concave surfaces or protrusions, and the cross-sectional shape of the accommodating space 4 is adapted to the shape of the power supply post.

[0060] This application adapts the cross-sectional shape of the accommodating space 4 to the shape of the power supply column, thereby preventing the power supply column from being difficult to insert or remove due to an unsuitable cross-sectional shape of the accommodating space 4, which would increase the friction during insertion and removal and damage the nickel plating layer on the surface of the power supply column.

[0061] This application, by setting the contact surfaces of the first conductive part and the second conductive part as conductive sheets, arc-shaped concave surfaces, or protrusions, can adapt to power supply posts with different external shapes, and prevent uneven contact between the power supply post and the contact surfaces of the first conductive part and the second conductive part, which would lead to unstable power supply.

[0062] In another exemplary embodiment of this application, a power supply device for an electricity meter is provided. The power supply device includes an electricity meter and the side-pressure power supply fixture mentioned in any of the above embodiments. The electricity meter is provided with a power supply column, which is detachably nested with the accommodating space 4. The side-pressure power supply fixture supplies power to the electricity meter through the power supply column.

[0063] Specifically, the first direction mentioned in any of the above embodiments is the direction of linear movement of the moving plate, and both the moving plate and the adjustment structure are in this first direction.

[0064] This application uses the adjustment structure 2 to drive the moving plate 3 to move back and forth along the first direction, which can flexibly adjust the size of the accommodating space 4 in the first direction to make it larger or smaller, so as to realize the unobstructed insertion and removal of the power supply column and the accommodating space 4. At the same time, the accommodating space 4, whose size can be changed along the first direction, can be adapted to power supply columns of different thicknesses, increasing the adaptability of the tooling.

[0065] The unobstructed insertion and removal of the power supply column and the housing space 4 in this application reduces the electrical risks caused by the direct connection of exposed power lines to the power supply column of the meter in related technologies. It avoids the damage to the nickel plating layer on the surface of the power supply column caused by friction between the restrictive socket and the surface of the power supply column during the insertion and removal of the power supply column in related technologies. It also avoids the problem of module loosening caused by frequent insertion and removal of the power supply column in related technologies, which affects the power supply stability of the meter, and avoids the tooling costs caused by regularly replacing loose modules. Therefore, the unobstructed insertion and removal of the power supply column and the housing space 4 in this application not only reduces electrical risks and tooling costs, but also improves the service life of the meter and the power supply stability.

Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this application. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this application should still be covered by the claims of this application.
