[0028] As described in the background art, the electricity meter junction box, as a core component of the power metering system, undertakes the core functions of connecting the electricity meter, transformer and secondary circuit, and can safely complete operations such as meter calibration and equipment replacement under live conditions, significantly improving the operation and maintenance efficiency. The electricity meter junction box is widely used in scenarios such as industrial and commercial users and residential power distribution, covering multi - level power grid networks from low - voltage to high - voltage.

[0029] However, the electricity meter junction box is usually fixedly installed at the user access end, exposed to a complex environment for a long time, and faces multiple challenges. The existing design of the junction box has security loopholes and is easy to be tampered with for electricity theft.

[0030] For example, the redundant wiring holes of the voltage terminal may be bypassed by electricity thieves to directly connect to the load equipment, bypassing the metering module, thus avoiding electricity metering. The idle holes of the current terminal can form a concealed shunt path by short - circuiting wires or connecting high - resistance devices, resulting in metering errors. Moreover, the installation positions of the electricity meter junction boxes are usually scattered and the environment is complex (such as high temperature, humidity, dust, etc.), resulting in high inspection difficulty and long cycle, and it is difficult to detect abnormalities in a timely manner.

[0031] Such electricity - theft behaviors not only cause electricity loss, but may also lead to major safety accidents due to problems such as line short - circuit and insulation breakdown, seriously threatening the stable operation of the power grid and public safety.

[0032] In view of this, the present application provides an anti-stealing electricity junction box, which includes a base, multiple groups of terminal blocks, and a plugging member. The base is provided with a terminal area and a plugging area. Among them, the terminal area is used to install multiple groups of terminal blocks. Each group of terminal blocks corresponds to a wiring hole communicated with the side wall of the base, and the wiring hole facilitates the access of wires and ensures the stable transmission of current and voltage signals. The plugging area is arranged on the incoming line side and the outgoing line side of the terminal area, and a plugging hole communicated with the wiring hole is opened inside it. The plugging member is detachably inserted into the plugging hole. By adjusting the state of the plugging member, the conduction or plugging of the wiring hole can be flexibly controlled. In this way, it is convenient for operation and maintenance personnel to adjust the wiring configuration according to actual needs and plug the unused wiring holes. Thus, it can effectively prevent electricity stealers from bypassing the metering module by means of short-circuiting or shunting, significantly improving the safety and reliability of power metering.

[0033] In order to make the above-mentioned objects, features, and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present application.

[0034] Figure 1 It is a schematic structural diagram of the anti-stealing electricity junction box provided by the embodiment of the present application after removing the cover plate. Refer to Figure 1 As shown, the embodiment of the present application provides an anti-stealing electricity junction box. The anti-stealing electricity junction box 10 can effectively prevent electricity stealing behaviors such as short-circuiting and shunting, and can be used to connect an electric meter and a current transformer in a power system to ensure the accurate transmission and metering of current and voltage signals.

[0035] Refer to Figure 1 As shown, the anti-stealing electricity junction box 10 includes a base 100. The base 100, as the core support component of the anti-stealing electricity junction box 10, can be made of a high-strength insulating material, so as to provide stable mechanical support and electrical insulation performance for the anti-stealing electricity junction box 10. Exemplarily, the base can be made of a glass fiber reinforced nylon or polycarbonate composite material with excellent mechanical strength and electrical insulation performance.

[0036] The structural design of the base 100 has been topologically optimized, which can withstand the mechanical stress during installation and operation, and at the same time can provide a stable electrical isolation barrier to prevent the risk of short-circuit or electric leakage caused by insulation failure. In addition, the surface of the base 100 can be treated with moisture-proof and anti-corrosion to enhance its durability in a complex environment, prevent the anti-stealing electricity junction box 10 from aging, cracking or decreasing electrical performance due to long-term exposure, thereby extending the service life of the anti-stealing electricity junction box 10.

[0037] Specifically, the base 100 is provided with a terminal area 110. The terminal area 110 includes an incoming line area 111 and an outgoing line area 112. The incoming line area 111 is mainly used to connect the input wires from the power supply side or the current transformer. The outgoing line area 112 is used to connect the output wires leading to the electricity meter or the load device, and its layout is symmetric with the incoming line area, facilitating a regular wiring route. Among them, the wire access position of the incoming line area 111 is defined as the incoming terminal, and the wire leading-out position of the outgoing line area 112 is defined as the outgoing terminal. The incoming terminal and the outgoing terminal are respectively located on both sides of the width direction of the base 100.

[0038] Continue to refer to Figure 1 As shown, the anti-tampering junction box 10 further includes multiple groups of terminal blocks. Each group of terminal blocks 200 is sequentially arranged and installed in the terminal area 110, which can ensure reliable and low-impedance electrical connections for the wires from the current transformer, electricity meter, and external devices. The terminal blocks 200 can be divided into current terminal blocks 230, voltage terminal blocks 240, and grounding terminal blocks 250 according to functional requirements.

[0039] Among them, the current terminal blocks 230 are mainly used to carry the large current of the main circuit, usually connecting to the secondary side output of the current transformer to transmit the current signal to the electricity meter or other measuring devices. The voltage terminal blocks 240 are usually used to connect the voltage sampling circuit and access the voltage signal of the system (such as from a voltage transformer or directly taken from the busbar). The grounding terminal blocks 250 are an important part of the safety protection of the anti-tampering junction box 10, used to connect the protective grounding wire to ensure reliable grounding of the components of the anti-tampering junction box 10. In addition, the grounding terminal blocks 250 can also provide a low-impedance path for the fault current to prevent the equipment from being energized due to insulation damage or lightning strikes, etc., ensuring the safety of personnel and equipment. The grounding terminal blocks 250 usually adopt corrosion-resistant materials and can be provided with prominent markings to distinguish them from other functional terminal blocks.

[0040] Continue to refer to Figure 1 As shown, the terminal block 200 includes a terminal post 220 (for simplicity of illustration, Figure 1 only one group of terminal posts is shown as an example). Each group of terminal blocks 200 realizes electrical connection through the terminal post 220. The terminal post 220, as the core component for connecting wires, can be made of high-performance conductive materials. Exemplarily, the terminal post 220 can be made of high-purity oxygen-free copper to ensure excellent electrical conductivity and corrosion resistance.

[0041] The terminal post 220 and the base 100 can be fixed by a hot pressing and embedding process. This connection method can not only control the contact resistance below the standard limit value but also has excellent tensile strength and anti-fatigue characteristics, enabling the terminal post 220 to withstand the mechanical stress and temperature changes during long-term operation.

[0042] The terminal block 200 further includes a crimping screw 221. A threaded crimping hole may be provided at the top of the terminal post 220, and the crimping screw 221 can be screwed into the crimping hole (see Figure 1 as shown), and the crimping screw 221 can be used to press the wire tightly against the contact surface of the terminal post 220. The mechanical pressure generated by the crimping screw 221 can ensure a low-impedance and high-stability electrical connection between the wire and the terminal post 220. At the same time, it can prevent the wire from loosening and falling off due to vibration or external force, ensuring the reliability of the long-term operation of the anti-tampering junction box 10.

[0043] The top of the crimping screw 221 can be designed as a flat or cross-slot structure, which is convenient for operating with standard tools.

[0044] To further improve the operation and maintenance safety and operation transparency, an observation hole 222 may be provided on the terminal post 220, and the observation hole 222 communicates with the wiring hole. And, the observation hole 222 is located at one end of the terminal post 220 away from the incoming line end and the outgoing line end.

[0045] In this way, the operation and maintenance personnel can check the crimping quality of the secondary wire in real time through the observation hole 222 without disassembling the anti-tampering junction box 10 and the terminal post 220, significantly improving the inspection efficiency and operation safety.

[0046] Exemplarily, the operation and maintenance personnel can check whether the exposed length of the wire core meets the specification requirements through the observation hole 222. Or, it is also possible to check whether there is a phenomenon of mis-crimping the insulating layer at the crimping part through the observation hole 222. Thus, the risk of heating or open circuit caused by poor contact can be effectively prevented, ensuring the long-term stable operation of the anti-tampering junction box 10.

[0047] An observation window (not shown in the figure) may also be covered on the observation hole. The observation window can serve as a physical barrier and can effectively prevent foreign objects from entering the terminal post 220. The observation window can be made of a transparent flame-retardant material with a high light transmittance and high temperature resistance. Exemplarily, the observation window can be made of polycarbonate material, and its optical properties support clearly observing the internal state of the observation cover under complex lighting conditions. In addition, an anti-fog coating can be applied to the inner wall of the observation window to avoid the influence of fogging caused by temperature difference on the observation effect.

[0048] In addition, each set of terminal blocks 200 is equipped with a wiring hole (not shown in the figure). The wiring hole can serve as a connection channel between the wire and the terminal block 200, allowing the wire to pass through and make reliable contact with the terminal post 220 inside the terminal block 200. These wiring holes penetrate the side wall of the base 100 and can form a regular wiring channel, enabling the wires to be arranged orderly and avoiding electromagnetic interference or mechanical damage caused by messy wiring.

[0049] Of course, the wiring holes can also be processed with an inclined angle or chamfer to facilitate the insertion and fixation of wires, improving the convenience of operation and maintenance.

[0050] The base further includes a sealing area 120, which is arranged at the incoming line end and the outgoing line end of the terminal area 110 and is located at both side edges in the width direction of the base 100. A sealing hole 121 communicating with the wiring hole is provided in the sealing area 120.

[0051] Continue to refer to Figure 1 As shown, the anti-theft electricity connection box 10 further includes a sealing member 300, which is detachably installed in the sealing hole 121. The sealing member 300 can effectively seal the wiring holes of the wiring terminals 200, preventing electricity thieves from interfering with the normal operation of the metering module through illegal means such as short-circuiting or shunting, significantly improving the security and reliability of the power metering system, and providing a reliable technical guarantee for the anti-theft electricity management of power enterprises.

[0052] Figure 2 This is a side view of the sealing member in the anti-theft electricity connection box provided by the embodiment of the present application. Refer to Figure 2 As shown, the sealing member 300 includes a column body 310 and a head 320 connected to the column body 310. Among them, the column body 310 extends into the sealing hole 121, and the head 320 abuts against the surface of the sealing area 120 (see Figure 1 as shown).

[0053] To ensure the security of the power system and prevent illegal electricity use, the sealing member 300 also needs to be made of insulating material. Exemplarily, the sealing member 300 can be made of a high-performance engineering plastic with high dielectric strength and excellent weather resistance. In this way, it can be ensured that the sealing member 300 or the sealing hole 121 itself cannot form a conductive path, and even if an electricity thief directly contacts the surface of the sealing member 300 or the sealing hole 121, an effective current loop cannot be formed.

[0054] Moreover, the outer wall surface of the column body 310 of the sealing member 300 and the inner wall of the sealing hole 121 can cooperate to form a fully enclosed insulating barrier. In the non-conductive state, the side wall of the column body 310 can completely cover the inner wall of the wiring hole, ensuring that there are no gaps through which wires can pass, thus effectively eliminating the possibility of electricity theft.

[0055] In this way, the anti-theft electricity function can be realized from the aspects of material essence and structural coordination. At the same time, the insulation design can also effectively suppress the leakage risk caused by environmental factors such as humidity and pollution, ensure the stability of the metering signal, and ensure that the anti-theft electricity connection box 10 can still maintain stable protection performance during long-term use.

[0056] In a possible implementation, the on-off control of the wiring hole can be achieved by installing or removing the plug 300. Specifically, for the terminal 200 that needs to be wired, the corresponding plug 300 is directly removed to form an open wiring channel, facilitating the access and fixation of the wire. For the unused terminal 200, the plug 300 is retained to block the illegal access path, thus eliminating the risk of electricity theft. At this time, the column 310 of the plug 300 can be designed as a solid column.

[0057] Alternatively, for scenarios where the wiring configuration needs to be frequently adjusted or the anti-electricity-theft requirement is higher, the plug 300 also adopts a dynamic locking design. Its column 310 is rotatably installed in the plug hole 121, and a wire passing hole 311 is axially provided in the column 310 to support the selective access of the wire.

[0058] Specifically, when the column 310 rotates until the wire passing hole 311 communicates with the wiring hole, a through wire passing channel can be formed at this time, and the wire can pass through the passing channel and be reliably connected to the terminal 200 to meet the normal power consumption requirements. When the column 310 rotates until the hole wall of the wire passing hole 311 is blocked by the hole wall of the wiring hole, the access path of the wire is blocked at this time, which can effectively prevent illegal wiring and eliminate the possibility of electricity theft, ensuring the operation safety of the anti-electricity-theft junction box 10 and the accuracy of electric energy metering.

[0059] In this way, through the dynamic design of the plug 300, the intelligent management of the orientation of the wiring hole can be realized, and the access authority of the wire can be flexibly controlled by rotating the column 310. When it is necessary to rewire or add a new line, the authorized personnel only need to rotate the column 310 until the wire passing hole 311 is aligned with the wiring hole, and then the through wire passing channel can be opened to successfully complete the compliance wiring operation.

[0060] For the unused wiring hole, the column 310 is rotated to the locked state where the wire passing hole 311 is completely misaligned with the wiring hole. At this time, the side wall of the column 310 can form a physical barrier to completely block any illegal access of the wire.

[0061] With such a setting, it not only meets the flexible wiring requirements in the normal power consumption scenario but also effectively prevents electricity theft behaviors such as short-circuiting and cross-connecting through the mechanical locking principle. Moreover, the plug 300 is always installed in the anti-electricity-theft junction box 10 and does not need to be stored separately, reducing the management cost.

[0062] Figure 3 This is the top view of the plug in the anti-electricity-theft junction box provided by the embodiment of the present application. Refer to Figure 3 As shown, in a possible implementation, an indicating portion 321 can be further provided on the side of the end 320 facing away from the column 310. The indicating portion 321 can be used to visually display the orientation state of the wire passing hole 311.

[0063] The indicating part 321 can be a straight groove opened in the end head 320, and the extending direction of the straight groove is parallel or perpendicular to the extending direction of the wire passing hole 311. Exemplarily, if the direction of the straight groove is parallel to the extending direction of the wire passing hole 311, when the direction of the straight groove extends along the width direction of the anti-tampering junction box 10, it indicates that the wire passing hole 311 has penetrated through the wiring hole, and the terminal 200 is in the state of authorized wiring. When the direction of the straight groove extends along the length direction of the anti-tampering junction box 10, it indicates that the wire passing hole 311 is misaligned with the wiring hole, and the terminal 200 is in the anti-tampering locking state.

[0064] In addition, the straight groove can also have the function of a tool interface, and its width and depth are optimized and designed to form an interference fit with the tip of a flat-blade screwdriver. The operator can use the screwdriver to rotate and tighten the plugging member 300 through the flat groove, which improves the convenience of installation.

[0065] Of course, the plugging member 300 can also be integrated with an indicator light (not shown in the figure). In a low-illumination environment, the indicator light can provide auxiliary visual guidance to ensure that the maintenance personnel can quickly and accurately judge the on-off state of the wiring hole.

[0066] Figure 4 Schematic diagram of the wiring state of the anti-tampering junction box provided by the embodiment of the present application. Refer to Figure 4 As shown, in the state of authorized wiring (such as when the wiring hole needs to be connected to an external wire), rotate the cylindrical body 310 to align the wire passing hole 311 inside the cylindrical body 310 with the axis of the wiring hole, forming a continuous wire passing channel. At this time, the wire can be connected along the through path.

[0067] In the non-wiring state (such as an unused redundant wiring hole), the cylindrical body 310 is rotated to a preset angle (for example, 90°), so that the wire passing hole 311 of the cylindrical body 310 is blocked by the hole wall of the wiring hole. In this way, when the cylindrical body 310 is at a non-connected angle, the side wall of the wire passing hole 311 can form a physical barrier, and any cable trying to be forcibly inserted will be blocked by the side wall of the cylindrical body 310. Thus, illegal operation paths such as short-circuiting and cross-connecting can be effectively blocked, eliminating the risk of electricity theft.

[0068] Figure 5 Schematic diagram of the structure of the anti-tampering junction box provided by the embodiment of the present application. Refer to Figure 5 As shown, the anti-tampering junction box 10 further includes a cover plate 400, and the cover plate 400 is detachably connected to the base 100. Exemplarily, the cover plate 400 can be quickly installed and disassembled with the base 100 through an anti-reverse buckle structure or screws.

[0069] It should be noted that after the cover plate 400 is connected to the base 100, external physical intervention cannot directly contact or rotate the plugging member 300. Thus, it can be ensured that the unused wiring holes are in a locked state where the wire passing holes 311 and the wiring holes are misaligned, so as to completely block illegal conduction paths such as short-circuiting and cross-connecting.

[0070] In addition, the cover plate 400 and the plugging member 300 can be set as transparent parts. Exemplarily, the cover plate 400 can be made of a transparent engineering plastic with high light transmittance and impact resistance. In this way, the operation and maintenance personnel can directly observe the wiring state inside the anti-theft electricity connection box 10 and the orientation of the plugging member 300 without opening the cover plate, significantly improving the daily inspection efficiency and reducing the operation and maintenance complexity.

[0071] The edge where the cover plate 400 contacts the base 100 can also be embedded with an electromagnetic shielding layer and an elastic sealing strip, which can meet the protection requirements while maintaining the visualization function, and effectively resist dust, water vapor and external electromagnetic interference.

[0072] After the cover plate 400 of the anti-theft electricity connection box 10 is connected to the base 100, an anti-unsealing label device (not shown in the figure) can be provided at the joint of the cover plate 400 and the base 100. Exemplarily, the anti-unsealing label device can be a metal or plastic sealing block with a unique number, which is fixed by crimping after the lead sealing wire passes through the corresponding holes of the cover plate 400 and the base 100. Any attempt to open the cover plate will cause the lead sealing wire to break or the sealing block to be damaged. This kind of damage trace cannot be restored and is visible to the naked eye, which not only physically blocks unauthorized personnel from contacting the internal plugging member 300, but also can provide intuitive evidence of electricity theft behavior for power inspection, so as to form a multi-dimensional protection system.
