Description

Technical Field

[0001] This utility model relates to the field of conductive equipment technology for electrical cabinets, and in particular to a conductive connector for electrical cabinets with low resistance. Background Technology

[0002] Grounding copper busbars are strip-shaped conductive components made of high-purity copper (or tin-plated copper). Their shape can be designed as straight or curved to meet installation requirements, and they often have pre-drilled connection holes. As the core connector in the electrical cabinet grounding system, they are typically connected to other copper busbars via bolts. Utilizing the low resistivity of copper, they create a low-impedance path, quickly dissipating fault current or leakage current and ensuring the safety of electrical equipment and personnel. Traditionally, grounding copper busbars are connected by bolts. While this method ensures a good foundation connection, the limited space inside the cabinet makes it difficult to tighten tools like wrenches due to obstruction from surrounding components and cabinet frame parts. This restricts the operating space and makes it difficult to tighten to the specified torque. Insufficient torque directly affects the tightness of the connection. Utility Model Content

[0024] Example

[0025] like Figures 1 to 3 As shown, this utility model proposes a conductive connector for low-resistance electrical cabinets, comprising a pair of grounding copper busbars 1. Each end of the grounding copper busbar 1 has a mounting hole 11, which provides an installation position for a locking rod 2, enabling a mating connection between the grounding copper busbar 1 and the locking rod 2. The locking rod 2 is movably installed within the mounting hole 11, inserted into the aligned mounting hole 11, and connected to the grounding copper busbar 1 via a slider mechanism, providing a foundation for the screw sleeve 3 to be screwed in place. An anti-slip groove is provided at the end of the locking rod 2 away from the gear 21, allowing manual pressing of the anti-slip groove to ensure that the locking rod 2 does not slip within the mounting hole 11 when the screw sleeve 3 is rotated.

[0026] Among them, such as Figure 2 and Figure 3 As shown, the locking rod 2 is equipped with a slider mechanism that engages with the mounting hole 11. The slider mechanism includes multiple telescopic grooves 22 arranged in a circular array at one end of the locking rod 2. A first spring 23 is fixedly connected inside each telescopic groove 22, providing elastic support for the telescopic locking block 24, allowing it to pop out or retract into the telescopic groove 22. A telescopic locking block 24 is fixedly connected to the end of the first spring 23 away from the inner wall of the telescopic groove 22, engaging with the mounting hole 11. The telescopic locking block 24 pops out under the action of the first spring 23, engaging with the inner wall of the mounting hole 11, thus achieving initial fixation between the locking rod 2 and the grounding copper busbar 1. The telescopic locking block 24 has an arc-shaped abutment surface 241 that automatically retracts into the telescopic groove 22 after abutting against the mounting hole 11. The arc-shaped abutment surface 241 is located on the telescopic locking block 24 and is pressed by the inner wall of the mounting hole 11 during insertion, causing the telescopic locking block 24 to automatically retract into the telescopic groove 22.

[0027] In addition, such as Figures 1 to 3 As shown, the locking rod 2 has a locking mechanism at its end that secures the ends of a pair of grounding copper busbars 1. The locking mechanism includes a screw sleeve 3 screwed onto the end of the locking rod 2. The screw sleeve 3 is screwed onto the end of the locking rod 2 and tightened by rotation to fit against the grounding copper busbars 1, thus securing the pair of grounding copper busbars 1. A U-shaped screw rod 31 is fixedly connected to the outer wall of the screw sleeve 3. The U-shaped screw rod 31 facilitates manual rotation to tighten or loosen the screw sleeve 3 and also provides a mounting carrier for the anti-reverse mechanism.

[0028] It is worth noting that, such as Figures 1 to 3As shown, the locking mechanism is equipped with an anti-reverse mechanism that opens by manual pressing and pinching. The anti-reverse mechanism is slidably connected to a pair of U-shaped sleeves 32 inside the U-shaped lever 31. The U-shaped sleeves 32 move under the action of the second spring 35, driving the connecting plate 33 and the locking teeth 34 to move. The second spring 35 is fixedly connected inside the U-shaped sleeve 32, providing elastic support for the U-shaped sleeve 32, causing it to drive the locking teeth 34 to mesh with the gear 21. The end of the second spring 35 away from the U-shaped sleeve 32 is fixedly connected to the U-shaped lever 31. The end of the locking lever 2 near the spiral sleeve 3 is fixedly connected to the gear 21. The gear 21 meshes with the locking teeth 34, restricting the spiral sleeve 3 from reversing. The bottom end of the U-shaped sleeve 32 is fixedly connected to the connecting plate 33. The bottom end of one of the connecting plates 33 is fixedly connected to the locking teeth 34 that lock the gear 21. When the locking teeth 34 mesh with the gear 21, they restrict the rotation of the gear 21, thereby preventing the spiral sleeve 3 from reversing. A pair of U-shaped sleeves 32, a connecting plate 33, and a second spring 35 are all symmetrically arranged with the spiral sleeve 3 as the center.

[0029] Furthermore, such as Figure 3 As shown, the anti-reverse mechanism also includes multiple pairs of rotating seats 36 fixedly connected to the U-shaped sleeve 32. A rotating rod 37 is rotatably connected to the middle of each pair of rotating seats 36. The two ends of the rotating rod 37 are rotatably connected to the rotating seat 36 and the central pressing rod 38, respectively, converting the movement of the central pressing rod 38 into the sliding of the U-shaped sleeve 32. A pair of central pressing rods 38 are provided inside the U-shaped screw rod 31. The central pressing rods 38 are located inside the U-shaped screw rod 31 and drive the U-shaped sleeve 32 to move via the rotating rod 37. A central pressing head 39 is fixed in the middle of the rotating rod 37. The end of the rotating rod 37 away from the rotating seat 36 is rotatably connected to the end of the central pressing rod 38. A central pressing head 39 is fixedly connected to the middle of the central pressing rod 38, facilitating manual pressing and driving the central pressing rod 38 to move inwards into the U-shaped screw rod 31.

[0030] In this embodiment, when using the conductive connector for low resistance in electrical cabinets, the mounting holes 11 of the two grounding copper busbars 1 must first be aligned, and then the locking rod 2 is inserted into the aligned mounting holes 11. During the insertion process, the inner wall of the mounting hole 11 will press the arc-shaped abutment surface 241 of the telescopic block 24, causing the telescopic block 24 to compress the first spring 23 and retract into the telescopic groove 22; when the locking rod 2 is fully inserted, the telescopic block 24 pops out under the elastic restoring force of the first spring 23, locking the inner wall of the mounting hole 11, thus achieving the initial connection and fixation between the grounding copper busbar 1 and the locking rod 2.

[0031] If it is necessary to manually rotate the U-shaped screw rod 31 to fix the screw sleeve 3 to a pair of grounding copper busbars 1, first press the pair of center pressing heads 39 to drive the corresponding center pressing rod 38 to move into the U-shaped screw rod 31. The center pressing rod 38 is rotatably connected to the end of the center pressing rod 38 and the rotating seat 36 through the two ends of the rotating rod 37, thereby pushing the two U-shaped sleeves 32 to open, while compressing the second spring 35. When one of the U-shaped sleeves 32 moves, the locking tooth 34 is disengaged from the gear 21 through the connecting plate 33, releasing the anti-reverse restriction. At this time, the U-shaped screw rod 31 can be rotated. Before this, the locking rod 2 needs to be fixed to prevent it from sliding in the mounting hole 11. Then, the U-shaped screw rod 31 drives the screw sleeve 3 to screw tight at the end of the locking rod 2 until the screw sleeve 3 is tightly fitted with the grounding copper busbar 1, thus completing the fastening connection of the two grounding copper busbars 1. At this time, under the elastic support of the second spring 35, the U-shaped sleeve 32 drives the locking tooth 34 to mesh with the gear 21 at the end of the locking rod 2 through the connecting plate 33. The meshing relationship between the gear 21 and the locking tooth 34 restricts the spiral sleeve 3 from reversing, ensuring the stability of the connection.

[0032] The entire process does not require wrenches or other tools; connection and disassembly can be completed through the mechanical cooperation between components. The anti-reverse mechanism effectively prevents the connection from becoming loose, which solves the problem of limited operation in confined spaces and ensures the tightness of the connection and low resistance characteristics.

[0033] The preferred embodiments of this utility model described above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
