Description

Technical Field

[0001] This application relates to the field of electrical maintenance equipment technology, and in particular to a grounding wire connection device. Background Technology

[0002] During power outage maintenance of low-voltage distribution network lines, installing grounding wires is a crucial safety measure to ensure the personal safety of workers and prevent accidental energization and induced electric shock. With the continuous advancement of intelligent distribution network construction, low-voltage switchgear, as the core equipment for power distribution and control, has seen a significant increase in internal integration. This results in generally smaller spacing between adjacent low-voltage switches within the cabinet, making the space for installing grounding wires extremely limited. This causes considerable inconvenience to on-site operations and places higher demands on operational standardization.

[0003] Currently, low-voltage grounding wires mostly use traditional clamping methods, requiring workers to manually strip the insulation layer of the conductor before clamping it. This process is cumbersome, time-consuming, and frequent stripping can damage the conductor's insulation, potentially leading to safety hazards such as leakage, short circuits, or even equipment burnout over the long term. Furthermore, manual operation in confined spaces is limited by the range of motion, making it easy to accidentally touch adjacent, energized equipment, posing a high risk of electric shock. In summary, current grounding wire installation methods are ill-suited to the development trend of intelligent power distribution networks and actual maintenance needs, exhibiting drawbacks such as complex operation, low efficiency, and high safety risks. Summary of the Invention

[0004] Therefore, it is necessary to provide a grounding wire connection device to address the problems of complex operation, low work efficiency, and high safety risks associated with installing grounding wires.

[0005] This invention provides a grounding wire connection device, the grounding wire connection device comprising: A conductive mechanism includes a conductive clamp and a first wire. The conductive clamp is connected to one end of the first wire. The conductive clamp is used to electrically connect to the wire to be grounded. The conductive clamp is capable of piercing the insulation layer of the wire to be grounded. A grounding switch, wherein the grounding switch is provided with a first terminal and a second terminal, and the other end of the first conductor is electrically connected to the first terminal; A grounding mechanism, comprising a second conductor and a grounding pin, wherein one end of the second conductor is electrically connected to a second terminal and the other end of the second conductor is electrically connected to the grounding pin; An adjustment mechanism is provided, which is drivenly connected to the conductive clamp. The adjustment mechanism is used to drive the conductive clamp to clamp or release the wire to be grounded.

[0006] In one embodiment, the conductive clamp includes a first clamping member, a second clamping member, and an adjustment component. The first clamping member and the second clamping member are movably connected. The adjustment component is mounted on the first clamping member and is drivenly connected to the second clamping member. The first clamping member and the second clamping member clamp or release the wire to be grounded through the adjustment component.

[0007] In one embodiment, the first clamping member has a first tooth on the side facing the second clamping member, and the second clamping member has a second tooth on the side facing the first clamping member. Both the first tooth and the second tooth are used to pierce the insulation layer of the conductor to be grounded.

[0008] In one embodiment, the adjustment assembly includes a first fastener and a second fastener. One end of the first fastener is movably connected to the first clamping member. The second clamping member has an adjustment hole. The first fastener is movably inserted through the adjustment hole. The second fastener is movably disposed at the end of the first fastener away from the first clamping member. The second fastener is used to drive the second clamping member and the first clamping member to move towards or away from each other to clamp or release the wire to be grounded.

[0009] In one embodiment, the adjustment assembly further includes a limiting member movably mounted to the first fastener and disposed between the first clamping member and the second clamping member, the limiting member being used to limit the minimum clamping angle of the conductive clamp.

[0010] In one embodiment, the adjustment mechanism includes a drive unit, an insulating rod, and a connector. The insulating rod is connected to the drive unit, the drive unit is driven to the connector, and the connector is detachably driven to the second fastener.

[0011] In one embodiment, the insulating rod is provided with a first adjustable joint, and the drive unit is provided with a second adjustable joint, the first adjustable joint and the second adjustable joint being movably connected.

[0012] In one embodiment, the grounding wire connection device further includes a protective component and a warning light. The protective component is electrically connected to the grounding switch, and the warning light is electrically connected to the grounding switch. When the grounding switch is energized, the protective component is used to prevent the grounding switch from performing opening and closing operations.

[0013] In one embodiment, the grounding wire access device further includes a cabinet, the grounding switch and the protective component are both installed inside the cabinet, and the warning light is located on the outer wall of the cabinet.

[0014] In one embodiment, both the conductive mechanism and the first terminal include at least two, and the conductive mechanism and the first terminal are connected in a one-to-one correspondence.

[0015] The aforementioned grounding wire connection device employs a conductive clamp capable of piercing the insulation layer. The clamp is installed onto the conductor to be grounded, and an adjustment mechanism drives the clamp to tighten. This allows the clamp to directly penetrate the insulation layer and surface oxide film without stripping the insulation, establishing a reliable electrical connection between the clamp and the conductor. The clamp is then connected to a grounding switch via a first wire, and the grounding switch is connected to a grounding pin via a second wire. The grounding pin is then inserted into the ground, completing the grounding operation. This piercing conductive clamp directly penetrates the insulation layer and surface oxide film to form a reliable electrical connection with the conductor, fundamentally avoiding insulation damage, leakage, and short-circuit hazards associated with traditional wire stripping operations. This significantly improves wiring safety and extends line lifespan. Furthermore, the adjustment mechanism allows for clamping and loosening, simplifying and quickly reducing the risk of accidental contact with live equipment in confined spaces. This enhances the safety and reliability of maintenance work, reduces operation time, and offers advantages such as ease of operation, high efficiency, and low safety risk.

[0025] See Figure 1 and Figure 2 This diagram illustrates the structure of a grounding wire connection device according to an embodiment of this application. The grounding wire connection device includes a conductive mechanism 100, a grounding switch 210, a grounding mechanism 300, and an adjusting mechanism 400. The conductive mechanism 100 includes a conductive clip 110 and a first conductor 120. The conductive clip 110 is connected to one end of the first conductor 120 and is used to electrically connect the conductor 10 to be grounded. Specifically, the conductive clip 110 can pierce the insulation layer of the conductor 10 to be grounded, thereby allowing the conductive clip 110 to be directly electrically connected to the unstripped conductor 10 to be grounded.

[0026] For example, the grounding wire connection device can be applied to various application scenarios such as the outgoing side of low-voltage switchgear, the outgoing end of power poles, and old lines.

[0027] The grounding switch 210 has a first terminal 211 and a second terminal 212, and the other end of the first conductor 120 is electrically connected to the first terminal 211. Exemplarily, both the first terminal 211 and the second terminal 212 are terminal blocks.

[0028] The grounding mechanism 300 includes a second conductor 310 and a grounding pin 320. One end of the second conductor 310 is electrically connected to the second terminal 212, and the other end of the second conductor 310 is electrically connected to the grounding pin 320.

[0029] The adjustment mechanism 400 is driven to connect to the conductive clamp 110. The adjustment mechanism 400 is used to drive the conductive clamp 110 to clamp the conductor 10 to be grounded, so that the conductive clamp 110 pierces the insulation layer, or to drive the conductive clamp 110 to release the conductor 10 to be grounded.

[0030] The grounding wire connection device described in this application uses a conductive clip 110 capable of piercing the insulation layer. The conductive clip 110 is installed on the conductor 10 to be grounded, and the adjusting mechanism 400 drives the conductive clip 110 to clamp. This allows the conductive clip 110 to directly penetrate the insulation layer and surface oxide film without peeling off the insulation layer, thus forming a reliable electrical connection between the conductive clip 110 and the conductor 10 to be grounded. Then, the conductive clip 110 is connected to the grounding switch 210 through the first wire 120, and the grounding switch 210 is connected to the grounding pin 320 through the second wire 310. The grounding pin 320 is used to insert into the ground, thereby completing the grounding operation of the conductor 10 to be grounded.

[0031] The grounding wire connection device described in this application uses a piercing conductive clamp 110 that can directly penetrate the insulation layer and surface oxide film to form a reliable electrical connection with the conductor 10 to be grounded. This fundamentally avoids the insulation damage, leakage, and short-circuit hazards of the conductor 10 to be grounded caused by traditional wire stripping operations, significantly improving wiring safety and line lifespan. Moreover, the conductive clamp 110 can be driven to clamp and loosen via the adjustment mechanism 400, making operation simple and quick. This greatly reduces the risk of accidental contact with live equipment in confined spaces, improves the safety and reliability of maintenance operations, and reduces operation time. It has the advantages of convenient operation, high work efficiency, and low safety risk.

[0032] In an optional embodiment, such as Figure 1 and Figure 2 As shown, both the conductive mechanism 100 and the first terminal 211 include at least two, and the conductive mechanism 100 and the first terminal 211 are connected in a one-to-one correspondence.

[0033] This embodiment sets up at least two conductive mechanisms 100 and a corresponding number of first terminals 211, and connects the conductive mechanisms 100 and the first terminals 211 one-to-one. This allows for simultaneous grounding of multiple conductors 10 to be grounded, eliminating the need for individual installation. This effectively meets the needs of multi-circuit grounding scenarios such as centralized maintenance of distribution areas and large-scale defect elimination, significantly reducing the number of grounding operations and overall operation time. It further improves the efficiency of low-voltage distribution network maintenance, reduces labor intensity and power outage duration, and makes the grounding wire access device more integrated, more practical, and better suited to the requirements of efficient operation and maintenance of modern distribution networks.

[0034] Combination Figure 3 and Figure 4The diagram shows a schematic of the structure of the conductive clip 110 of the grounding wire access device in one embodiment of the present application. In some embodiments, the conductive clip 110 includes a first clamping member 111, a second clamping member 112, and an adjustment component 113. The first clamping member 111 and the second clamping member 112 are movably connected. The adjustment component 113 is installed on the first clamping member 111 and is drivenly connected to the second clamping member 112. The first clamping member 111 and the second clamping member 112 clamp or release the wire 10 to be grounded through the adjustment component 113.

[0035] This embodiment uses a first clamping member 111, a second clamping member 112, and an adjustment component 113. By utilizing the movable connection between the first clamping member 111 and the second clamping member 112, and by driving the second clamping member 112 relative to the first clamping member 111 through the adjustment component 113, reliable clamping and releasing of the grounding wire 10 can be achieved. The operation is convenient and flexible, and it can be adapted to grounding wires 10 of different specifications. The structural design of the conductive clamp 110 is reasonable, which can ensure stable contact with the grounding wire 10 during the clamping process and ensure the reliability of grounding continuity.

[0036] In one exemplary embodiment, such as Figure 3 and Figure 4 As shown, the first clamping member 111 and the second clamping member 112 are hinged. The adjusting component 113 is located at the end of the first clamping member 111 and the second clamping member 112 away from the hinge position, so that the adjusting component 113 drives the first clamping member 111 and the second clamping member 112 to rotate towards each other to clamp the wire to be grounded 10 and complete the wiring operation.

[0037] In an optional embodiment, such as Figure 3 and Figure 4 As shown, the first clamping member 111 has a first tooth 1111 on the side facing the second clamping member 112, and the second clamping member 112 has a second tooth 1121 on the side facing the first clamping member 111. Both the first tooth 1111 and the second tooth 1121 are used to pierce the insulation layer of the conductor 10 to be grounded. Specifically, both the first tooth 1111 and the second tooth 1121 serve as piercing teeth.

[0038] This embodiment, by providing a first tooth 1111 on the first clamping member 111 and a second tooth 1121 on the second clamping member 112, can simultaneously penetrate the insulation layer and oxide film on the surface of the conductor to be grounded 10 during the locking process of the conductive clamp 110. This ensures that the conductive clamp 110 and the metal core of the conductor to be grounded 10 form a reliable electrical stripping-free connection, fundamentally solving the safety hazards such as insulation layer damage and leakage caused by traditional wire stripping operations. It enables rapid grounding of the line, reduces the difficulty of operation, ensures the safety and reliability of the grounding connection, provides strong support for the efficient and safe conduct of low-voltage distribution network maintenance operations, and helps to improve the standardization level of maintenance operations.

[0039] In one exemplary embodiment, the main bodies of the first clamping member 111 and the second clamping member 112 are both made of brass material with high conductivity to improve the current carrying capacity of the conductive clamp 110.

[0040] Furthermore, both the first clamping member 111 and the second clamping member 112 are covered with a flexible insulating outer skin and an insulating outer shell, which effectively prevents accidental contact with the live conductive clamp 110 and improves the safety of the conductive clamp 110 when operating in narrow spaces.

[0041] In an optional embodiment, such as Figure 3 and Figure 4 As shown, the adjustment assembly 113 includes a first fastener 1131 and a second fastener 1132. One end of the first fastener 1131 is movably connected to the first clamping member 111. The second clamping member 112 has an adjustment hole 1122. The first fastener 1131 is movably inserted through the adjustment hole 1122, and the second fastener 1132 is movably disposed at the end of the first fastener 1131 away from the first clamping member 111. The second fastener 1132 is used to drive the second clamping member 112 and the first clamping member 111 to move towards or away from each other to clamp or release the grounding wire 10. Specifically, the adjustment mechanism 400 drives the second fastener 1132 to move on the first fastener 1131 to drive the conductive clamp 110 to clamp or release.

[0042] In this embodiment, the cooperation between the first fastener 1131 and the second fastener 1132 allows the first clamping member 111 and the second clamping member 112 to move towards or away from each other, driven by the adjusting mechanism 400. This enables precise clamping and loosening of the grounding wire 10. The adjusting component 113 has a compact and reliable structure, is easy to operate and flexible in adjustment, and is suitable for confined working spaces such as low-voltage switchgear. It can effectively reduce the difficulty of manual operation, avoid operational errors in confined spaces, and ensure the stability of the conductive clamp 110 when clamping, further improving the safety, convenience and efficiency of the grounding wire connection device.

[0043] In an optional embodiment, such as Figure 3 and Figure 4 As shown, the adjustment assembly 113 also includes a limiting member 1133, which is movably mounted on the first fastener 1131 and is disposed between the first clamping member 111 and the second clamping member 112. The limiting member 1133 is used to limit the minimum clamping angle of the conductive clamp 110.

[0044] This embodiment uses a limiting member 1133 to physically restrict the adjustment stroke of the first fastener 1131 and the second fastener 1132, thus limiting the range of motion of the first clamping member 111 and the second clamping member 112. During the adjustment mechanism 400's operation of the second fastener 1132, once the limiting member 1133 contacts the second clamping member 112, the second fastener 1132 cannot continue to be driven, thereby limiting the maximum piercing depth of the first tooth 1111 and the second tooth 1121. This ensures that the first tooth 1111 and the second tooth 1121 stop penetrating the grounding wire 10 after completing the connection, effectively preventing excessive embedding of the first tooth 1111 and the second tooth 1121 that could cause squeezing, strand breakage, or damage to the grounding wire 10. While ensuring reliable conductivity, this improves the protection of old wires or multi-strand flexible wires.

[0045] In one exemplary embodiment, such as Figure 3 and Figure 4 As shown, the first fastener 1131 is a locking screw, and the second fastener 1132 is a locking nut. One end of the locking screw is hinged to the first clamping member 111, and the other end of the locking screw passes through the adjustment hole 1122. The locking nut is installed at the end away from the locking screw and away from the hinge position. By rotating the locking nut, it can move along the axial direction of the locking screw, thereby driving the first clamping member 111 and the second clamping member 112 to move towards or away from each other by operating the locking nut.

[0046] Furthermore, such as Figure 3 and Figure 4 As shown, the limiting member 1133 is an adjusting nut, which is located on the locking screw between the first clamping member 111 and the second clamping member 112. By changing the position of the adjusting nut on the locking screw, the minimum clamping angle between the first clamping member 111 and the second clamping member 112 can be limited, thus physically restricting the adjustment stroke of the adjusting assembly 113. During the tightening process of the locking nut driven by the conductive mechanism, once the adjusting nut contacts the second clamping member 112, the locking nut cannot be screwed in further, thereby limiting the maximum piercing depth of the conductive clamp 110 on the grounding wire 10.

[0047] In an optional embodiment, such as Figure 1 and Figure 2 As shown, the adjustment mechanism 400 includes a drive unit 410, an insulating rod 420, and a connector 430. The insulating rod 420 is connected to the drive unit 410, the drive unit 410 is driven to connect with the connector 430, and the connector 430 is detachably driven to connect with the second fastener 1132.

[0048] In this embodiment, the insulating rod 420 is connected to the drive unit 410. The drive unit 410 and the connector 430 form a drive engagement. The connector 430 is used to form a detachable drive connection with the second fastener 1132, enabling remote, insulated operation of the second fastener 1132. This effectively improves the safety of operations in confined spaces, avoids the risk of electric shock caused by workers accidentally touching live equipment, simplifies the operation process, and improves the efficiency of grounding wire installation and removal. Specifically, the insulating rod 420 can ensure good electrical insulation performance, meeting the safety specifications for low-voltage distribution network maintenance. Its overall structure is simple and reliable, providing stable support for the remote installation and removal and safe operation of the conductive clamp 110, further enhancing the practicality and safety of the grounding wire connection device.

[0049] In one exemplary embodiment, such as Figure 1 and Figure 2 As shown, the drive unit 410 is an electric wrench, and the connector 430 is a locking sleeve, which is adapted for use with a locking nut. The locking sleeve is connected to the locking nut, and the electric wrench drives the locking sleeve to rotate, thereby driving the locking screw through the electric wrench.

[0050] Furthermore, the electric wrench has a preset locking torque range of 0.8 N·m to 2.5 N·m, which enables precise control of the clamping force of the conductive clamp 110, avoids excessive force due to human operation, and prevents damage to the grounding wire 10 and the conductive clamp 110 while ensuring grounding reliability.

[0051] In an optional embodiment, such as Figure 1 and Figure 2 As shown, the insulating rod 420 is provided with a first adjustable joint 421, and the drive unit 410 is provided with a second adjustable joint 411. The first adjustable joint 421 and the second adjustable joint 411 are movably connected.

[0052] This embodiment uses the first adjustable connector 421 and the second adjustable connector 411 to form a movable connection between the insulating rod 420 and the drive unit 410. This allows for flexible adjustment of the drive angle according to the narrow and complex working space where the grounding wire 10 is installed. This enables the grounding wire connection device to complete the installation operation smoothly in a confined space, effectively avoiding the problems of inconvenient operation and easy contact with live parts in traditional rigid structures. This significantly reduces the risk of operation and improves the convenience and efficiency of grounding wire installation.

[0053] In one exemplary embodiment, such as Figure 1 and Figure 2 As shown, the first adjustable connector 421 and the second adjustable connector 411 are adjustable angle Torx heads. The electric wrench is connected to the insulating rod 420 through the adjustable angle Torx head, thereby allowing for flexible adjustment of the angles of the electric wrench and the locking socket, facilitating the operation of locking nuts in confined spaces or high-altitude environments.

[0054] In one exemplary embodiment, the insulating rod 420 is configured as a folding insulating operating rod, which can be adjusted by the operator as needed to complete the grounding installation from a safe distance, making it particularly suitable for narrow spaces and high-altitude working environments.

[0055] In an optional embodiment, such as Figure 1 and Figure 2 As shown, the grounding wire connection device also includes a protective component 220 and a warning light 230. The protective component 220 is electrically connected to the grounding switch 210, and the warning light 230 is electrically connected to the grounding switch 210. When the grounding switch 210 is energized, the protective component 220 is used to prevent the grounding switch 210 from performing opening and closing operations.

[0056] This embodiment adds a protective component 220 and a warning light 230 electrically connected to the grounding switch 210. When the grounding switch is in an energized grounding state, the protective component 220 provides mechanical obstruction, preventing the grounding switch 210 from performing opening and closing operations, thus forming an effective electrical and mechanical interlock. This structurally eliminates safety hazards caused by accidental closing or misoperation. When the first terminal 211 and the second terminal 212 of the grounding switch 210 are energized, the grounding switch 210 cannot perform opening or closing operations under load, and the energized warning light 230 illuminates red, effectively preventing misoperation and providing a visual indication of the grounding status. This effectively solves the problem of the lack of reliable interlocking between the grounding status and switch operation in traditional grounding devices, significantly improving the safety and reliability of low-voltage distribution network maintenance operations and ensuring the safety of equipment and personnel.

[0057] In one exemplary embodiment, the protective component 220 is an electromagnetic push-pull valve. This valve can quickly extend and retract electromagnetically when the grounding circuit is energized, forming a reliable mechanical interlock with the grounding switch 210. It is sensitive and responsive, effectively achieving forced interlocking between the grounding state and switch operation, physically eliminating the risk of accidental closing and misoperation. In an optional embodiment, such as Figure 1 and Figure 2 As shown, the grounding wire connection device also includes a cabinet 240, with the grounding switch 210 and protective component 220 installed inside the cabinet 240, and a warning light 230 located on the outer wall of the cabinet 240. By configuring the cabinet 240, the grounding switch 210 and protective component 220 are integrated and installed inside the cabinet 240, while the warning light 230 is placed on the outer wall of the cabinet 240. This achieves enclosed protection and standardized installation of internal components such as the grounding switch 210 and protective component 220, improving the overall structural stability and protection level of the grounding wire connection device.

[0058] In one exemplary embodiment, the cabinet 240 is further provided with an opening and closing baffle and an insulating protective structure on the outside to further reduce the risk of accidental contact.

[0059] In an exemplary embodiment, the cabinet 240 is provided with an inlet and an outlet, the inlet being for the first wire 120 to pass through, and the outlet being for the second wire 310 to pass through.

[0060] In one exemplary embodiment, the grounding pin 320 is detachably connected to the second wire 310 via a third fastener. The conductive clip 110 is detachably connected to the first wire 120 via a fourth fastener. Specifically, the third and fourth fasteners can be bolts and nuts, facilitating assembly and disassembly and improving efficiency.

[0061] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
