Description

Technical Field

[0001] This utility model relates to the field of grounding device technology, specifically to a split-type grounding device. Background Technology

[0002] In electrical work, grounding clamps are now widely used to prevent electrostatic induction electric shock from nearby live conductors or to ensure safety in case of accidental energization. Some connectors have grounding pins. In actual structures, the grounding pin inside the connector core needs to be connected to the metal shell of the connector. However, the existing grounding connection structures are often quite complex, and the installation process is also cumbersome.

[0003] For equipment that requires regular component inspection, maintenance, or replacement, the complex structure of existing grounding devices increases the number of steps required for equipment shutdown operations, prolongs downtime for maintenance, is detrimental to the continuous and stable operation of the equipment, and significantly reduces the stability and reliability of current and signal transmission. Utility Model Content

[0004] To address the shortcomings of existing technologies, a split-type grounding device is proposed, which solves the problem that the complex structure of the grounding device in the above-mentioned background technology increases the operation steps of equipment shutdown, prolongs the downtime for maintenance, and is not conducive to the continuous and stable operation of the equipment.

[0005] To achieve the above objectives, the present invention proposes the following technologies: A split-type grounding device includes a first plug-in part and a second plug-in part. The first plug-in part is provided with a plug connector, and the second plug-in part is provided with a plug socket for plugging the plug connector. The plug socket has an installation groove, and the installation groove cooperates with the plug connector to limit the positioning so as to realize the assembly of the first plug-in part and the second plug-in part.

[0006] Furthermore, the socket has a socket hole that matches the size of the connector, the end of the connector has a chamfer distributed circumferentially, and the opening edge of the socket hole has a guide surface to guide the connector in accordance with the chamfer.

[0007] Furthermore, the end of the connector is provided with a locking block protruding from the surface of the connector, and the connector base is provided with a connector groove located on one side of the connector hole. The connector groove is used to avoid the locking block, thereby facilitating the insertion of the connector into the connector hole.

[0008] Furthermore, both the connector and the insertion hole are cylindrical, and the mounting groove is formed on the inner wall of the insertion hole. The mounting groove extends circumferentially along the insertion hole, and its end is connected to the insertion groove, so that after the locking block is inserted into the mounting groove, the first connector can be rotated to achieve locking with the second connector.

[0009] Furthermore, the depth of the mounting groove into the connector gradually decreases in the direction away from the mounting groove, so that when the locking block slides in the mounting groove, it gradually pushes the connector against the inner wall of the connector hole to achieve a tight connection between the connector and the connector.

[0010] Furthermore, the first plug-in portion also includes a first insulating sleeve sleeved outside the plug-in connector, and the second plug-in portion also includes a second insulating sleeve sleeved outside the plug-in base. The plug-in end of the first insulating sleeve is tapered, and the plug-in end of the second insulating sleeve is provided with a groove to cooperate with the tapered end of the first insulating sleeve. The plug-in base is located at the bottom of the groove.

[0011] Furthermore, one end of the plug is connected to a grounding plug, the first insulating sleeve is wrapped around the grounding plug, and the end of the plug away from the plug hole is provided with a terminal for connecting a conductive wire, and the second insulating sleeve is wrapped around the terminal.

[0012] Furthermore, the connector is hexagonal, and the second insulating sleeve has mounting holes that match the shape of the connector, thereby preventing the connector from rotating inside the second insulating sleeve.

[0013] Compared with the prior art, the comprehensive effects brought about by this utility model include: By setting up a separate first and second plug-in part, the plug-in and the plug socket with the mounting groove are matched to realize the rapid assembly and separation of the separate structure. The above structure overcomes the problems of cumbersome operation and low efficiency caused by the traditional grounding wire fastening or winding method. The mounting groove provides a limiting structure. When the plug-in is inserted into the plug socket, the plug-in structure can be engaged or locked with the contour of the mounting groove by rotation and other operations, thereby realizing the mechanical locking and electrical connection of the two parts, ensuring the mechanical stability after connection, preventing accidental detachment when subjected to external force, and greatly improving the safety and reliability of grounding connection.

[0016] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] In this document, terms such as “up,” “down,” “left,” “right,” and “top” indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] like Figures 1 to 6 As shown, a split-type grounding device includes a first plug-in part 1 and a second plug-in part 2. The first plug-in part 1 is provided with a plug connector 3, and the second plug-in part 2 is provided with a plug socket 4 for plugging the plug connector 3. The plug socket 4 has an installation groove 5, and the installation groove 5 cooperates with the plug connector 3 to limit the positioning so as to realize the assembly of the first plug-in part 1 and the second plug-in part 2.

[0019] This embodiment provides a split-type grounding device, which is mainly used for grounding connection of equipment or lines in power systems. It has the advantages of reliable connection, simple operation and good insulation performance.

[0020] The core connection structure of this device consists of a first plug-in part 1 and a second plug-in part 2. The first plug-in part 1 serves as a movable plug-in end, with a plug connector 3 at its front end; the second plug-in part 2 serves as a fixed socket end, with a plug socket 4. The plug socket 4 is not a simple through hole, but rather has a specially designed mounting groove 5 with a specific contour. When the plug connector 3 is inserted into the plug socket 4, by rotating or other operations, the specific structure on the plug connector 3 can engage or lock with the contour of the mounting groove 5, thereby achieving mechanical locking and electrical connection between the two parts.

[0021] By cooperating with the plug 3 and the plug socket 4 with the mounting groove 5, the quick assembly and separation of the split structure is realized. The above structure overcomes the problems of cumbersome operation and low efficiency caused by the traditional grounding wire using bolt fastening or winding. The mounting groove 5 provides a limiting structure to ensure the mechanical stability after connection and prevent accidental detachment when subjected to external force, which greatly improves the safety and reliability of grounding connection.

[0022] In the split grounding device of this embodiment, the plug socket 4 is provided with a plug hole 6 that matches the size of the plug 3. The end of the plug 3 is provided with a chamfer distributed in the circumferential direction. The opening edge of the plug hole 6 is provided with a guide surface to facilitate the chamfer to guide the plug 3.

[0023] Specifically, the connector 4 is provided with a mating hole 6 that precisely matches the cylindrical connector 3. The end of the connector 3 is machined with an annular chamfer, and the opening edge of the mating hole 6 is correspondingly machined with a beveled or arc-shaped guide surface. During the mating process, even if there is a slight alignment deviation, the chamfer of the connector 3 will first contact the guide surface of the mating hole 6. Under the continued application of insertion force, the guide surface will generate a radial corrective force on the connector 3, causing it to automatically slide into and align with the center of the mating hole 6.

[0024] The aforementioned guide structure significantly improves the ease of insertion and reduces the margin for error. The combination of the chamfer and the guide surface acts as a centering mechanism, allowing operators to easily complete the initial insertion without precise alignment, thus reducing operational difficulty. This advantage is particularly evident in low-light or space-constrained working environments. Simultaneously, this guide structure prevents hard collisions between the metal connector and the edge of the insertion hole, effectively preventing damage to components and extending the product's lifespan.

[0025] In the split grounding device of this embodiment, the end of the plug 3 is provided with a locking block 7 protruding from the surface of the plug 3, and the plug base 4 is provided with a plug groove 8 located on one side of the plug hole 6. The plug groove 8 is used to avoid the locking block 7, thereby facilitating the insertion of the plug 3 into the plug hole 6.

[0026] To achieve the rotational locking function, a radially protruding locking block 7 is provided at the end of the connector 3. Correspondingly, inside the connector base 4, a radially extending insertion groove 8 is formed on one side of the insertion hole 6. The width of the insertion groove 8 is slightly larger than the width of the locking block 7. During initial insertion, the operator needs to align the locking block 7 with the insertion groove 8. At this time, the locking block 7 can pass through the insertion groove 8 without obstruction, allowing the connector 3 to be fully inserted into the bottom of the insertion hole 6.

[0027] The key benefit of this design is that it achieves a two-step connection mechanism of "insertion first, then rotation locking". The insertion slot 8 provides a dedicated channel for the locking block 7, ensuring that the insertion connector 3 can be smoothly positioned. This not only defines the correct assembly path and avoids misoperation, but also provides the structural basis for the subsequent rotation locking action, which is a key link in achieving a fast and reliable connection.

[0028] In the split grounding device of this embodiment, both the plug 3 and the plug hole 6 are cylindrical. The mounting groove 5 is opened on the inner wall of the plug hole 6. The mounting groove 5 extends circumferentially along the plug hole 6 and its end is connected to the plug groove 8 so that after the locking block 7 is inserted into the mounting groove 5, the first plug part 1 can be rotated to achieve locking with the second plug part 2.

[0029] In this embodiment, both the connector 3 and the connector hole 6 are cylindrical in shape for easy processing and alignment. The mounting groove 5 is actually an arc-shaped channel formed on the inner wall of the connector hole 6, which together with the connector groove 8 forms an L-shaped channel structure. One end of the mounting groove 5 is connected to the connector groove 8, and the other end extends a distance along the circumference of the connector hole 6. When the locking block 7 on the connector 3 is inserted to the bottom through the connector groove 8, the operator can rotate the first connector part 1 clockwise or counterclockwise, and the locking block 7 will slide from the connector groove 8 into the circumferential part of the mounting groove 5.

[0030] The combination of the cylindrical fit and the circumferentially extended mounting groove 5 creates an extremely stable and reliable locking method: after the locking block 7 slides into the circumferential part of the mounting groove 5, it is restricted by the groove wall and cannot be withdrawn axially, forming a mechanical interlock with extremely strong pull-out resistance; the operation is intuitive and simple, and the connection can be completed with just "insert and twist". The action is simple, the feel is clear, and the operator can clearly perceive whether the connection is in place.

[0031] In the split grounding device of this embodiment, the depth of the mounting groove 5 into the plug socket 4 gradually decreases in the direction away from the plug groove 8, so that when the locking block 7 slides in the mounting groove 5, it gradually pushes the plug 3 to abut against the inner wall of the plug hole 6, so as to achieve a tight connection between the plug 3 and the plug socket 4.

[0032] In this application, the depth of the mounting groove 5 is not uniform. The bottom surface of the mounting groove 5 is an inclined slope. Preferably, the mounting groove 5 is spiral-shaped on the hole wall, with its depth being the deepest at the end near the insertion groove 8, and gradually becoming shallower as it extends circumferentially. When the operator rotates the first insertion part 1, the locking block 7 slides along this gradually shallowing groove bottom and is gradually pushed upward by the inclined surface of the groove bottom (i.e., towards the central axis of the insertion hole 6), thereby forcing the entire insertion part 3 to produce a small radial displacement, so that its outer surface is tightly pressed against the inner wall of the insertion hole 6.

[0033] The aforementioned structure achieves both tighter electrical connections and enhanced mechanical connections. By actively applying radial pressure through the mechanical structure, the contact between the connector 3 and the socket 4 changes from a simple surface contact to a tight, interference-fit contact. This significantly increases the contact area, reduces contact resistance, and avoids safety hazards such as overheating and electrical sparks caused by poor contact, ensuring reliable grounding conductivity. The ramp design eliminates clearances, preventing loosening due to vibration during operation and improving vibration resistance and long-term stability.

[0034] In the split grounding device of this embodiment, the first plug-in part 1 further includes a first insulating sleeve 9 sleeved on the outside of the plug-in 3, and the second plug-in part 2 further includes a second insulating sleeve 10 sleeved on the outside of the plug-in seat 4. The plug-in end of the first insulating sleeve 9 is conical, and the plug-in end of the second insulating sleeve 10 is provided with a groove to cooperate with the conical end of the first insulating sleeve 9. The plug-in seat 4 is located at the bottom of the groove.

[0035] To ensure operational safety, the conductive metal components (plug 3 and plug socket 4) of the first plug part 1 and the second plug part 2 are both wrapped with insulating material. The first insulating sleeve 9 wraps the plug 3, and the second insulating sleeve 10 wraps the plug socket 4. The front end of the first insulating sleeve 9 is designed as a frustum cone, while the front end of the second insulating sleeve 10 has a matching conical groove. When the two plug parts are connected, the conical end of the first insulating sleeve 9 will be tightly embedded in the groove of the second insulating sleeve 10.

[0036] The insulating sleeve completely isolates live parts, effectively preventing electric shock and short circuits. The fit between the conical surface and the groove forms a sealed structure, effectively preventing dust and moisture from entering the connection interface, thus improving the product's protection level and enabling it to adapt to harsher working environments. Furthermore, the conical fit allows for physical contact before electrical contact, further aiding alignment and providing cushioning and protection for the internal metal connectors.

[0037] In the split grounding device of this embodiment, one end of the plug 4 is connected to a grounding plug 11, the first insulating sleeve 9 is wrapped around the grounding plug 11, the end of the plug 3 away from the plug hole 6 is provided with a terminal for connecting a conductive wire, and the second insulating sleeve 10 is wrapped around the terminal.

[0038] Specifically, in terms of wiring connections, the socket 4 of the second connector 2 is connected to the equipment requiring grounding via the grounding pin 11, and the connector 3 of the first connector 1 has a terminal for connecting the conductive wire of the grounding wire. The insulating sleeve extends and completely covers the grounding pin 11 and the terminal, exposing only the necessary connection parts.

[0039] The above-mentioned design ensures the safety and neatness of the external wiring of the device. The extended insulation sleeve insulates all exposed conductive parts, avoiding the risk of accidental contact during installation and maintenance. At the same time, this integrated encapsulation design makes the product structure more complete, improves the continuity of insulation protection, and enhances the overall mechanical strength.

[0040] In the split-type grounding device of this embodiment, the plug-in 4 is hexagonal, and the second insulating sleeve 10 is provided with an assembly hole that matches the shape of the plug-in 4, thereby preventing the plug-in 4 from rotating inside the second insulating sleeve 10.

[0041] To prevent the internal connector 4 from rotating along with the first connector 1 during locking, this embodiment designs the connector 4 to be a regular hexagon, while the second insulating sleeve 10 has a precisely matching regular hexagonal mounting hole inside. Through this polygonal fit, the connector 4 is effectively prevented from rotating and fixed in the second insulating sleeve 10.

[0042] This anti-rotation design ensures the effectiveness and reliability of operation. It solves the problem of the entire second connector 2 rotating during tightening, allowing the torque applied to the first connector 1 to be fully used to drive the locking block 7 within the mounting slot 5, thereby achieving the desired tight connection. Otherwise, if the connector 4 slips, the locking function will not be possible. This ensures the stable performance of the product design.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.
