[0002] In live-line work in power systems, it is often necessary to quickly connect or disconnect narrow-gap copper busbars. Traditional copper busbar connection methods typically use bolt tightening or wire clamp crimping. While these methods provide reliable connections, they have significant shortcomings in live-line working environments: First, the operation steps are cumbersome, requiring specialized tools to tighten each bolt individually, resulting in low assembly and disassembly efficiency and making it difficult to meet the needs of rapid operations; second, traditional wire clamps are bulky and cannot be inserted into the narrow gaps between copper busbars, limiting their applicability; third, the clamping mechanism lacks an effective anti-slip design, making it prone to loosening or slippage under vibration or external force, affecting the stability and safety of conductive contact; fourth, in some structures, if the operating handle is released after clamping, the jaws can easily detach on their own, failing to maintain a continuous and stable clamping force, posing a safety hazard. Summary of the Invention

Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0016] Example like Figure 1-6 As shown, a quick clamping structure for energized connection of a narrow-gap copper busbar includes a conductive copper column 1, a handle 2 fixedly fitted at the tail end of the conductive copper column 1, an insulating movable sleeve 3 movably fitted at the front end of the conductive copper column 1, a movable seat 4 movably fitted at the front end of the conductive copper column 1 and connected to the insulating movable sleeve 3, a fixed seat 5 fixedly fitted at the front end of the conductive copper column 1, two grippers 6 hinged to the fixed seat 5 in the middle and movably connected to the movable seat 4 at their ends, a conductive head 7 located between the two grippers 6 and embedded and fixed at the front end of the conductive copper column 1, and an adjusting stud 8 located at the center of the conductive copper column 1 and having one end threaded into the inside of the conductive head 7.

[0017] Specifically, through the coordinated operation of conductive copper pillar 1, handle 2, insulating movable sleeve 3, movable seat 4, fixed seat 5, two grippers 6, conductive head 7 and adjusting stud 8, a compact clamping structure integrating rapid opening and closing clamping and axial top pressure locking is constructed, providing basic architectural support for live rapid connection operations in narrow gap environments.

[0018] The conductive copper pillar 1 has a stud through hole 11 at its center. Specifically, the stud through hole 11 at the center of the conductive copper pillar 1 provides a precise axial guide channel for the adjusting stud 8, ensuring coaxiality and transmission stability during rotation adjustment. The conductive copper pillar 1 has a conductive head mounting hole 12 at the end facing the conductive head 7. The conductive head mounting hole 12 ensures the firmness and centering of the conductive head 7 during installation. The part where the conductive copper column 1 is assembled with the fixing base 5 is provided with an external threaded head 13 of the conductive copper column. The external threaded head 13 of the conductive copper column is screwed and fixed to the fixing base 5, which simplifies the assembly process and enhances the overall structural rigidity.

[0019] A limiting cavity 21 is provided on the inner side of the end of the handle 2 facing the insulating movable sleeve 3. Specifically, the limiting cavity 21 on the inner side of the handle 2 blocks and limits the top sleeve 34 of the insulating movable sleeve 3, effectively controlling the sliding stroke range of the insulating movable sleeve 3 and avoiding excessive pushing and pulling that could cause the gripper 6 to overtravel and become damaged or loose.

[0020] An internal thread 31 is provided on the inner side of the end of the insulating movable sleeve 3 facing the movable seat 4. A threaded adjusting sleeve 32 is screwed into the internal thread 31 and fixedly assembled with the insulating movable sleeve 3. A connecting part 33 is fixedly attached to the movable seat 4 after the threaded adjusting sleeve 32 extends forward and is embedded in the movable seat 4. A top sleeve 34 is integrally formed on the end of the insulating movable sleeve 3 facing the handle part 2. Specifically, the top sleeve 34 is embedded in the limiting cavity 21 and is blocked and limited by the limiting cavity 21.

[0021] It should be further explained that the insulating movable sleeve 3 is fixedly assembled with the threaded adjusting sleeve 32 through the internal thread 31, the connecting part 33 is embedded in the movable seat 4 to achieve linkage, and the top sleeve 34 cooperates with the limiting cavity 21 to realize the integration of insulating operation and power transmission, which not only ensures the safety of live operation, but also realizes precise axial control of the movable seat 4.

[0022] The movable seat 4 is provided with a fixed shaft 41 that is assembled with the gripper 6. The part of the movable seat 4 that is fitted with the conductive copper column 1 is provided with a connecting groove 42. Specifically, the connecting groove 42 is threadedly fixed to the connecting part 33 of the threaded adjusting sleeve 32.

[0023] It should be further explained that when it is necessary to control the two jaws 6 to engage and tighten the conductive copper busbar through the movable seat 4, or to control the two jaws 6 to loosen and disengage from the conductive copper busbar, the two jaws 6 can be controlled to engage or disengage by adjusting the threaded adjusting sleeve 32 by moving the insulating movable sleeve 3 back and forth.

[0024] The part where the fixing seat 5 is assembled with the conductive copper column 1 is provided with the fixing seat internal thread 51. Specifically, the fixing seat internal thread 51 of the fixing seat 5 is screwed and fixed with the conductive copper column external thread head 13, so that the fixing seat 5 can be fixedly installed with the conductive copper column 1.

[0025] The gripper 6 is first installed on the fixed seat 5 via a hinge shaft. Specifically, the linear motion of the movable seat 4 is efficiently converted into the rotational opening and closing motion of the gripper 6, resulting in precise transmission. The rear end of the gripper 6 is provided with an oblique groove 61. Specifically, the oblique groove 61 is assembled with the fixed shaft 41. When the movable seat 4 moves, the opening and closing of the two grippers 6 is controlled by the fixed shaft 41 moving in the oblique groove 61. The front end of the gripper 6 is provided with a claw hook 62 with barbs. When the two grippers 6 are engaged, the barbs of the claw hook 62 can squeeze the conductive copper busbar, which can play an anti-slip role.

[0026] The conductive head 7 is embedded in the conductive copper pillar 1 and has an internal threaded hole in the pillar 71. The conductive contact piece 72 with anti-slip texture is integrally formed on the front end of the pillar 71.

[0027] It should be noted that the post 71 of the conductive head 7 is embedded in the conductive copper post 1 for fixed installation, ensuring a stable and reliable conductive path; the conductive contact piece 72 with anti-slip texture at the front end increases the contact area and frictional resistance when in contact with the copper busbar, which not only reduces the contact resistance and improves the conductivity, but also enhances the positioning and anti-slip ability under pressure.

[0028] The tail end of the adjusting stud 8 is provided with a hexagonal post 81 for connecting a socket wrench, and the front end of the adjusting stud 8 is provided with a stud head 82 for engaging with the conductive head 7. Specifically, the hexagonal post 81 at the tail end of the adjusting stud 8 facilitates quick connection and force application of the socket wrench, and the stud head 82 and the conductive head 7 are threaded together to achieve precise ejection and retraction control.

[0029] When the mechanism needs to quickly connect the conductive copper busbar, first slide the insulating movable sleeve 3 in the direction of arrow D. The insulating movable sleeve 3 pulls the threaded adjusting sleeve 32, and the threaded adjusting sleeve 32 pulls the movable seat 4, so that the two jaws 6 engage. Then, connect the hexagonal column 81 through the external socket wrench, and rotate the hexagonal column 81 through the socket wrench to drive the adjusting stud 8 to rotate, pushing out the conductive head 7 to squeeze the conductive copper busbar. At this time, after the conductive head 7 applies pressure to the conductive copper busbar, it will cooperate with the two jaws 6 to lock the conductive copper busbar. At this time, the insulating movable sleeve 3 can be released, but the jaws 6 will not loosen.

[0030] When the mechanism needs to quickly detach from the conductive copper busbar, the hexagonal post 81 is connected via an external socket wrench. Rotating the hexagonal post 81 with the socket wrench causes the adjusting stud 8 to rotate, retracting the conductive head 7 and removing it from the conductive copper busbar. At this point, the conductive head 7 releases the conductive copper busbar. Then, by sliding the insulating movable sleeve 3 in the direction of arrow E, the insulating movable sleeve 3 pushes against the threaded adjusting sleeve 32, and the threaded adjusting sleeve 32 pushes against the movable seat 4, causing the two grippers 6 to open, thus detaching from the conductive copper busbar.

[0031] The above embodiments of the present invention are not intended to limit the scope of protection of the present invention. The implementation of the present invention is not limited thereto. All other modifications, substitutions or alterations made to the above structure of the present invention based on the above content of the present invention, in accordance with ordinary technical knowledge and common practice in the field, without departing from the basic technical idea of ​​the present invention, shall fall within the scope of protection of the present invention.
