Technical Field

[0002] Cable connection structure refers to the part that realizes electrical connection and physical fixation between cables or between cables and other equipment. This structure usually includes cable connectors and related components, and is designed to ensure stable and reliable transmission of current or signals, and withstand certain mechanical stress and environmental factors.

[0003] After searching, the Chinese patent with announcement number CN219575964U provides a cable connection mechanism, which fixes the wire core entering the limit sleeve by means of a fixed bolt, and then presses the pressure blocks provided on both sides of the limit sleeve inwardly through the adjustment block and the fixed sleeve. The pressure blocks drive the limit blocks to clamp the wire core inward, and at the same time, the inner wall of the rear end of the fixed sleeve clamps the conical bite sleeve inward, and then the conical bite sleeve clamps the wire core inward, fixing the end and middle of the wire core again, thereby improving the overall tensile strength. The multiple fastenings are not easy to fall off, increasing the overall safety, facilitating connection and fastening, and eliminating certain safety hazards.

[0004] However, during use, it was found that the connection stability of the cable connection mechanism was poor. In an application environment with high vibration or dynamic load, the cable gradually loosened due to continuous small vibrations during use, which could easily lead to cable connection failure over time. When the cable was subjected to sudden or rapidly changing tension, the connection mechanism was difficult to maintain a stable connection state, which could easily lead to breakage or deformation of the cable connector, causing the cable connection to loosen or separate, affecting the use effect of the cable connection.

[0024] Beneficial effects of the present invention:

[0025] In the present invention, after one end of the two cable bodies to be connected is passed through the anti-slip component and the positioning sleeve, the cable core is inserted into the metal sleeve of the connecting insulating tube, so that the outer peripheral walls of the cable cores at both ends contact the inner wall of the metal sleeve. After the cable cores at both ends contact each other, the rotating block of the protective component is opened to rotate the adjusting handwheel, and the corresponding adjusting handwheel is rotated to drive the disc to rotate along the connecting insulating tube, and the push block is pushed to the side away from the connecting insulating tube by one end of the adjusting handwheel. The moving push block drives the insulating block and the semicircular block to move synchronously, so that the semicircular block and the insulating block slide along the U-shaped groove, so that the semicircular block and the conical block squeeze the cable core, so that the cable core and the metal sleeve are tightly pressed together, completing the electrical connection of the cable core, simplifying the cable connection process, improving the connection efficiency, ensuring the stable transmission of current or signals between cables, and facilitating the rapid disassembly and installation of the cable body.

[0026] When the adjusting hand wheel is opened, the chamfered block is separated from the C-shaped block by pulling the lever, and the rotating block can be pulled to rotate along the rotating shaft to open, which is convenient for the rotation opening and locking of the rotating block and the rotation use of the adjusting hand wheel. At the same time, the adjusting hand wheel is protected by the rotating block and the protective block, which reduces the risk of loosening or failure of the connection caused by accidentally touching the adjusting hand wheel during the installation process after the cable body is connected, thereby ensuring the stability and reliability of the connection between the cable body and the connecting insulating tube.

[0027] In the present invention, the positioning sleeve is pushed to slide along the outer wall of the cable body, and the positioning sleeve is abutted against the side wall of the clamp through the sealing ring. At this time, the corresponding claw is inserted into the inside of the slot, and the threaded end of the rotating tightening wheel is abutted against the outer peripheral wall of the positioning sleeve, so that the claw is tightly pressed against the slot to complete the clamping of the positioning sleeve and the clamp. When the positioning sleeve moves, the anti-slip component is driven to move synchronously, preventing the cable body from loosening or falling off during the connection process, thereby improving the stability and reliability of the connection. The positioning sleeve and the clamp are sealed by the sealing ring, which prevents external factors such as moisture and dust from invading the cable connection, thereby ensuring the sealing and safety of the cable connection.

[0028] In the present invention, the restoring force of the spring pushes the card block to be clamped and fixed in the positioning groove of the arc-shaped card belt, so that the two rubber pads are tightly pressed against the outer wall of the cable body. When the cable body moves to the side away from the connecting insulating tube, the arc block is driven by the tensile block to slide along the bracket, and the arc block drives the folding block to rotate along the rotating rod, so that the second anti-slip block moves upward to further squeeze the cable body, making it more firm when the cable body is pulled to move to both sides, improving the stability and anti-slip effect of the connection, enhancing the fixing effect between the cable body and the connecting component, improving the stability and anti-slip performance of the cable connection, effectively resisting external force, preventing the cable from falling off, facilitating installation and maintenance, preventing the cable body from accidentally falling off or loosening, thereby avoiding safety accidents that may be caused by cable failure, and improving the safety performance of the overall system.

[0029] In the present invention, the outer sheath resists physical damage and chemical corrosion in the external environment of the cable body, protecting the internal structure from being affected; the armor layer improves the mechanical strength of the cable body, enabling it to withstand stronger external forces and pressures, and is suitable for more severe working environments; the design of the insulation layer ensures electrical isolation between cable cores, reduces the risk of current leakage and short circuit, and ensures stable and reliable electrical performance of the cable; the filling of fillers reduces the gaps between cable cores, avoids internal stress concentration generated when the cable is bent or moved, and protects the integrity of the cable core and insulation layer; the outer sheath, armor layer and inner sheath together constitute a multiple protection system for the cable, effectively preventing damage to the internal structure of the cable from the external environment and extending the service life of the cable.

[0057] When the anti-slip assembly 7 is used, the first anti-slip block 701 is driven to move synchronously while the positioning sleeve 602 is installed, so that the first anti-slip block 701 is clamped with the outer wall of the cable body 2 through the arc groove 703, and then one of the tensile blocks 704 is rotated open along the other tensile block 704, so that the outer wall of the cable body 2 contacts the inner wall of one of the rubber pads 705, and then the other tensile block 704 is rotated in the opposite direction so that the inner wall of the other rubber pad 705 is clamped with the cable body 2. At this time, the tensile block 704 is pulled to move to the side away from the first anti-slip block 701. During the movement, the tensile block 704 at the lower end drives one of the second hinge seats 708 to move synchronously, so that the arc block 707 slides along the bracket 706;

[0058] The arc block 707 drives another second hinge seat 708 to move, so that the folding block 709 rotates along the rotating rod 710. The rotating folding block 709 pushes the third hinge seat 712 to move upward, so that the second anti-slip block 702 slides along the first anti-slip block 701, so that the second anti-slip block 702 squeezes and fixes the outer peripheral wall of the cable body 2 through the arc groove 703. After the second anti-slip block 702 is moved to a suitable height for use, the arc cassette 713 is inserted into the fixed block 715. At this time, the arc cassette 713 squeezes the card block 716 and slides outward along the fixed block 715. At this time, the spring 718 is compressed, so that the arc cassette 713 moves to a suitable position;

[0059] Through the restoring force of spring 718, the card block 716 is pushed to be clamped and fixed with the positioning groove 714 of the arc-shaped card belt 713, so that the two rubber pads 705 are tightly pressed against the outer wall of the cable body 2. When the cable body 2 moves to the side away from the connecting insulating tube 1, the arc block 707 is driven by the tensile block 704 to slide along the bracket 706, and the arc block 707 drives the folding block 709 to rotate along the rotating rod 710, so that the second anti-slip block 702 moves upward to further squeeze the cable body 2, making it more secure when the cable body 2 is pulled to move to both sides, improving the stability and anti-slip effect of the connection, enhancing the fixing effect between the cable body 2 and the connecting component, improving the stability and anti-slip performance of the cable connection, effectively resisting external force, preventing the cable from falling off, facilitating installation and maintenance, preventing the cable body 2 from accidentally falling off or loosening, thereby avoiding safety accidents that may be caused by cable failure, and improving the safety performance of the overall system. Example

[0060] like Figure 1 and Figure 12 As shown, this embodiment is based on the previous embodiment, and is different from the previous embodiment in that the cable body 2 includes an outer protective layer 9, an armor layer 10 is fixedly provided on the inner wall of the outer protective layer 9, an inner protective layer 11 is fixedly provided on the inner wall of the armor layer 10, an insulating layer 12 is fixedly provided inside the inner protective layer 11, multiple cable cores 3 are located inside the insulating layer 12, and the gaps between the multiple cable cores 3 and between the cable cores 3 and the insulating layer 12 are filled with fillers 13.

[0061] The outer sheath 9 resists physical damage and chemical corrosion in the external environment of the cable body 2 and protects the internal structure from being affected. The armor layer 10 improves the mechanical strength of the cable body 2, enabling it to withstand stronger external forces and pressures and be suitable for more severe working environments. The design of the insulating layer 12 ensures electrical isolation between the cable cores 3, reduces the risk of current leakage and short circuit, and ensures that the electrical performance of the cable is stable and reliable. The filling of the filler 13 reduces the gaps between the cable cores 3, avoids internal stress concentration generated when the cable is bent or moved, and protects the integrity of the cable core 3 and the insulation layer 12. The outer sheath 9, armor layer 10 and inner sheath 11 together constitute a multiple protection system for the cable, which effectively prevents the external environment from damaging the internal structure of the cable and extends the service life of the cable.

[0062] Working principle:

[0063] When in use, first, insert one end of the two cable bodies 2 to be connected through the anti-drop component 7 and the positioning sleeve 602, then insert the cable core 3 into the metal sleeve 4 of the connecting insulating tube 1, so that the outer peripheral walls of the cable core 3 at both ends contact with the inner wall of the metal sleeve 4, and after the cable cores 3 at both ends contact each other, open the rotating block 802 of the protective component 8 to rotate the adjusting hand wheel 504, and rotate the corresponding adjusting hand wheel 504 to drive the disc 505 to rotate along the connecting insulating tube 1, and push the push block 503 to the The moving push block 503 moves away from the side of the connecting insulating tube 1, and drives the insulating block 502 and the semicircular block 501 to move synchronously, so that the semicircular block 501 and the insulating block 502 slide along the U-shaped groove 506, so that the semicircular block 501 and the conical block 507 squeeze the cable core 3, so that the cable core 3 and the metal sleeve 4 are tightly pressed together, completing the electrical connection of the cable core 3, simplifying the cable connection process, improving the connection efficiency, ensuring the stable transmission of current or signals between the cables, and facilitating the rapid disassembly and installation of the cable body 2;

[0064] After adjusting the adjusting hand wheel 504 to a suitable position, the rotating block 802 is pushed to rotate along the rotating shaft 803. At this time, the chamfering block 806 is perpendicular to the rotating block 802 due to the tension of the tension spring 807. As the rotating block 802 moves, the rotating block 802 is driven to move synchronously. When the chamfering block 806 contacts the outer wall of the C-shaped block 805, the chamfering block 806 is pushed to rotate along the rotating block 802. At this time, the tension spring 807 is stretched. When the rotating block 802 contacts the protective block 801, the restoring force of the tension spring 807 causes the chamfering block 806 to be plugged into the C-shaped block 805, thereby fixing the rotating block 802.

[0065] When it is necessary to open the rotating block 802 and rotate the adjusting handwheel 504, after pulling the lever 804 to drive the chamfering block 806 to separate from the C-shaped block 805, the rotating block 802 can be pulled to rotate and open along the rotating shaft 803, which facilitates the rotation, opening and locking of the rotating block 802, and facilitates the rotation and use of the adjusting handwheel 504. At the same time, the adjusting handwheel 504 is protected by the rotating block 802 and the protective block 801, reducing the risk of loose connection or failure due to accidental contact with the adjusting handwheel 504 during the installation process after the cable body 2 is connected, thereby ensuring the stability and reliability of the connection between the cable body 2 and the connecting insulating tube 1.

[0066] After the cable core 3 is connected, the positioning sleeve 602 is pushed to slide along the outer wall of the cable body 2, and the positioning sleeve 602 is abutted against the side wall of the clamp 601 through the sealing ring. At this time, the corresponding claw 604 is inserted into the inside of the slot 605, and the threaded end of the rotating fastening wheel 606 is abutted against the outer wall of the positioning sleeve 602, so that the claw 604 is tightly pressed against the slot 605, completing the clamping of the positioning sleeve 602 and the clamp 601. When the positioning sleeve 602 moves, it drives the anti-slip component 7 to move synchronously, preventing the cable body 2 from loosening or falling off during the connection process, improving the stability and reliability of the connection, and the positioning sleeve 602 and the clamp 601 are sealed by the sealing ring to prevent external factors such as moisture and dust from invading the cable connection, ensuring the sealing and safety of the cable connection.

[0067] When the anti-slip assembly 7 is used, the first anti-slip block 701 is driven to move synchronously while the positioning sleeve 602 is installed, so that the first anti-slip block 701 is clamped with the outer wall of the cable body 2 through the arc groove 703, and then one of the tensile blocks 704 is rotated open along the other tensile block 704, so that the outer wall of the cable body 2 contacts the inner wall of one of the rubber pads 705, and then the other tensile block 704 is rotated in the opposite direction so that the inner wall of the other rubber pad 705 is clamped with the cable body 2. At this time, the tensile block 704 is pulled to move to the side away from the first anti-slip block 701. During the movement, the tensile block 704 at the lower end drives one of the second hinge seats 708 to move synchronously, so that the arc block 707 slides along the bracket 706;

[0068] The arc block 707 drives another second hinge seat 708 to move, so that the folding block 709 rotates along the rotating rod 710. The rotating folding block 709 pushes the third hinge seat 712 to move upward, so that the second anti-slip block 702 slides along the first anti-slip block 701, so that the second anti-slip block 702 squeezes and fixes the outer peripheral wall of the cable body 2 through the arc groove 703. After the second anti-slip block 702 is moved to a suitable height for use, the arc cassette 713 is inserted into the fixed block 715. At this time, the arc cassette 713 squeezes the card block 716 and slides outward along the fixed block 715. At this time, the spring 718 is compressed, so that the arc cassette 713 moves to a suitable position;

[0069] Through the restoring force of spring 718, the card block 716 is pushed to be clamped and fixed with the positioning groove 714 of the arc-shaped card belt 713, so that the two rubber pads 705 are tightly pressed against the outer wall of the cable body 2. When the cable body 2 moves to the side away from the connecting insulating tube 1, the arc block 707 is driven by the tensile block 704 to slide along the bracket 706, and the arc block 707 drives the folding block 709 to rotate along the rotating rod 710, so that the second anti-slip block 702 moves upward to further squeeze the cable body 2, making it more secure when the cable body 2 is pulled to move to both sides, improving the stability and anti-slip effect of the connection, enhancing the fixing effect between the cable body 2 and the connecting component, improving the stability and anti-slip performance of the cable connection, effectively resisting external force, preventing the cable from falling off, facilitating installation and maintenance, preventing the cable body 2 from accidentally falling off or loosening, thereby avoiding safety accidents that may be caused by cable failure, and improving the safety performance of the overall system.

[0070] The outer sheath 9 resists physical damage and chemical corrosion in the external environment of the cable body 2 and protects the internal structure from being affected. The armor layer 10 improves the mechanical strength of the cable body 2, enabling it to withstand stronger external forces and pressures and be suitable for more severe working environments. The design of the insulating layer 12 ensures electrical isolation between the cable cores 3, reduces the risk of current leakage and short circuit, and ensures that the electrical performance of the cable is stable and reliable. The filling of the filler 13 reduces the gaps between the cable cores 3, avoids internal stress concentration generated when the cable is bent or moved, and protects the integrity of the cable core 3 and the insulation layer 12. The outer sheath 9, armor layer 10 and inner sheath 11 together constitute a multiple protection system for the cable, which effectively prevents the external environment from damaging the internal structure of the cable and extends the service life of the cable.
