Description

Technical Field

[0001] The present application relates to the technical field of conductive connectors, and in particular to a conductive connector for a cable fitting grounding system. Background Art

[0002] The cable grounding system is one of the important safety measures in the power system. During the operation of high-voltage single-core cables, the metal sheath of the cable will generate induced voltage during normal operation and is easily broken down under overvoltage conditions, resulting in multiple grounding faults. This fault will not only increase the circulating current loss, reduce the cable's current carrying capacity and service life, but may also endanger personal safety. Therefore, it is necessary to use a reasonable grounding method and grounding system to limit the induced voltage and circulating current to protect the safe operation of the cable.

The copper strip joints at both ends of the copper strip body are welded with an electrode seat on the separated side, the electrode seat is penetrated by a through hole, and a tin cylinder is coaxially arranged on the inner side of the through hole. Mounting rings are provided at both ends of the tin cylinder, which can protect the bending portion and prevent the bending portion from deformation and breakage during practical use.

[0004] The special-shaped conductive copper tape soft connectors in the related technology use welding to fix the cables during the connection process. The connection method is relatively complicated and tests the operator's skills. Dangerous situations are prone to occur during the fixing process. At the same time, welding operations are even more prone to danger during the fixing process. Improper wiring and debugging of welding equipment may cause electric shock accidents. When the operator touches the live welding equipment or damaged welding cable, the strong current instantly passes through the human body, which may cause serious electric shock injuries or even endanger life.

[0005] Therefore, it is necessary to provide a conductive connector for a cable fitting grounding system to solve the above problems. Utility Model Content

[0024] Based on this, in order to improve the technical problems existing in the related art in that the method of connecting cables is relatively complicated, which tests the operator's skills and is prone to dangerous situations during the fixing process, the embodiments of the present application provide the following solutions.

[0025] Please also refer to Figures 1 to 6 An embodiment of the present application provides a conductive connector for a cable fitting grounding system. The conductive connector 1 for a cable fitting grounding system includes a connector 1, a copper cylinder 11, and a clamping assembly 2. The copper cylinder 11 is arranged on the connector 1, and the clamping assembly 2 is arranged on the copper cylinder 11.

[0026] In some embodiments, please refer to Figures 1 to 6 The clamping assembly 2 includes a fixed ring 21, a connecting ring 22, a rotating ring 23, a ramp block 24, an abutment column 25, an abutment plate 26 and a limiter 28. The fixed ring 21 is fixedly arranged on the copper cylinder 11, the connecting ring 22 is arranged on the fixed ring 21, the rotating ring 23 is rotatably arranged in the connecting ring 22, the ramp block 24 is fixedly arranged on the rotating ring 23, a connecting hole 29 is provided on the connecting ring 22, the abutment column 25 is slidably provided on the rotating ring 23 through the connecting hole 29, the abutment plate 26 is provided on the end of the abutment column 25 away from the connecting ring 22, a connecting groove 27 is provided on the connecting ring 22, and the limiter 28 is provided on the rotating ring 23 through the connecting groove 27. A plurality of separation grooves 12 are evenly arrayed on the copper cylinder 11.

[0027] With such a configuration, when the user uses the conductive connector 1 to connect the cable, the user connects the cable to the copper cylinder 11, and by dialing the limit piece 28 in the connecting groove 27, the rotating ring 23 is driven to rotate by rotating the limit piece 28, and the rotating ring 23 drives the inclined block 24 on the rotating ring 23 to rotate. The inclined block 24 abuts the abutment column 25 during the rotation process, and the abutment column 25 drives the abutment plate 26 to press the copper cylinder 11. A plurality of separation grooves 12 are evenly arranged on the copper cylinder 11, so that the tube body can better adapt to local deformation during the pressing process. When the pressing force acts on the tube body, the separation grooves 12 allow the tube body to deform to a certain extent on both sides of the groove without causing local stress concentration due to excessive overall rigidity, thereby improving the fit and stability between the tube body and the connector 1, thereby better pressing the copper cylinder 11 and the cable. In this way, through the compression assembly 2, the rotating ring 23 and the inclined block 24 are driven to rotate by rotating the limit member 28, and the inclined block 24 abuts the abutment column 25, thereby driving the abutment plate 26 to press the copper cylinder 11, so that the copper cylinder 11 and the cable are tightly pressed, effectively avoiding the interruption or instability of current transmission caused by poor contact, and thus achieving a tight connection of the cable by simply toggling the limit member 28 and rotating the operation. The installation process is relatively simple and fast, does not require complicated tools and processes, reduces the frequency and difficulty of maintenance, and reduces maintenance costs.

[0028] In some embodiments, please refer to Figure 2 and Figure 4The limiting member 28 includes a fixed column 281, a connecting column 282 and a paddle 283. The fixed column 281 is arranged on the rotating ring 23 through the connecting groove 27. The connecting column 282 is movably arranged on the fixed column 281. The paddle 283 is arranged on the end of the connecting column 282 away from the fixed column 281. A contact groove 284 is provided on the connecting column 282, and an abutment spring 285 is provided in the abutment groove 284. A button 286 is provided on the other end of the abutment spring 285. A limiting hole 287 is provided on the fixed column 281 to match the button 286. A plurality of limiting blocks 288 are evenly arranged in an array on both sides of the connecting groove 27 on the connecting ring 22, and a connecting ear 289 is provided on the end of the paddle 283 close to the limiting block 288.

[0029] With such arrangement, when the user rotates the rotating ring 23 through the paddle 283 to drive the inclined block 24 to abut against the abutment column 25 and the abutment plate 26, thereby squeezing the copper tube 11 to compress the cable, when the copper tube 11 is in a compressed state, by pressing the button 286, the button 286 compresses the abutment spring 285 in the abutment groove 284, and extends and retracts the connecting column 282 downward. When the button 286 reaches the limiting hole 287, the abutment spring 285 rebounds the button 286, causing the button 286 to pass through the limiting hole 287, thereby fixing the position between the fixing column 281 and the connecting column 282, so that the connecting ear 289 below the paddle 283 is clamped between the two adjacent limiting blocks 288, thereby fixing the position of the rotating ring 23. In this way, by pressing the button 286 and utilizing the elasticity of the abutment spring 285 and the cooperation of the limiting hole 287, the position of the rotating ring 23 can be accurately fixed, so that the relative positions of the inclined block 24, the abutment column 25 and the abutment plate 26 can be kept stable, so that the pressing force of the copper cylinder 11 on the cable can be kept constant, avoiding the change of the pressing force caused by the loosening of the rotating ring 23, and ensuring the stability of the connection between the cable and the copper cylinder 11. When the copper cylinder 11 is pressing the cable, fixing the position of the rotating ring 23 can effectively prevent the rotating ring 23 from loosening due to external vibration or impact. This avoids loosening or falling off between the copper tube 11 and the cable, and improves the reliability of the connection. The user only needs to rotate the rotating ring 23 through the paddle 283, and then press the button 286 to fix the position of the rotating ring 23. The operation process is simple and quick, and does not require complicated tools or tedious steps, which improves work efficiency. By accurately fixing the position of the rotating ring 23, it can ensure that the clamping force of the copper tube 11 on the cable remains consistent during each operation. This is of great significance for ensuring the electrical and mechanical properties of the cable connection, especially in application scenarios where precise control of the clamping force is required.

[0030] The implementation principle of the conductive connector of the cable hardware grounding system in the embodiment of the present application is as follows: when the user uses the conductive connector 1 to connect the cable, by connecting the cable to the copper cylinder 11, by toggling the paddle 283, the rotating ring 23 is driven to rotate by rotating the fixed column 281, and the rotating ring 23 drives the inclined block 24 on the rotating ring 23 to rotate, and the inclined block 24 abuts the abutting column 25 during the rotation process, and the abutting column 25 drives the abutting plate 26 to press the copper cylinder 11. A plurality of separation grooves 12 are uniformly arranged on the copper cylinder 11, so that the tube body can better adapt to local deformation during the pressing process. When the pressing force acts on the tube body, the separation grooves 12 allow the tube body to deform to a certain extent on both sides of the groove without causing local stress concentration due to excessive overall rigidity, thereby improving the connection between the tube body and the connection. The fit and stability between the parts 1 are improved, thereby better pressing the copper tube 11 and the cable. When the user rotates the rotating ring 23 through the paddle 283 to drive the inclined block 24 to abut the abutment column 25 and the abutment plate 26, thereby squeezing the copper tube 11 to compress the cable, when the copper tube 11 is in the compressed state, by pressing the button 286, the button 286 compresses the abutment spring 285 in the abutment groove 284, and extends and retracts the connecting column 282 downward. When the button 286 reaches the limiting hole 287, the abutment spring 285 rebounds the button 286, so that the button 286 passes through the limiting hole 287, thereby fixing the position between the fixing column 281 and the connecting column 282, so that the connecting ear 289 under the paddle 283 is clamped between the two adjacent limiting blocks 288, thereby fixing the position of the rotating ring 23.

[0031] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
