[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention, through the overall design of the quick-connect mechanism, allows the cable end to be inserted into its inner side. The extension shaft can then be manually rotated. Since the threads at both ends of the bidirectional lead screw are in opposite directions, two mirror sliders can be driven to slide towards each other on the outer wall of the limiting rod, simultaneously driving the strip rod to move. This allows the spikes to pierce through the outer sheath of the cable and abut against the outer wall of the inner conductor of the cable, thus achieving an electrical connection between the cable conductors. This design eliminates the need for cable stripping before connection and the need for reassembling the connector, significantly improving connection efficiency. Furthermore, the cover plate and connector housing are sealed together to form a protective structure that covers the spike portion, isolating it from air, moisture, pollutants, etc., reducing interference from the external environment and maintaining the stability of the electrical connection. The spikes are divided into two groups, symmetrically piercing the cable to provide more balanced contact pressure and a more stable connection. After the spikes pierce the outer sheath of the cable and abut against the outer wall of the inner conductor, as the rotating wheel continues to move the bar rod, the slide bar will slide on the bar rod. At the same time, the connecting block will compress the elastic element to avoid the problem of the spikes easily piercing the conductor. Meanwhile, it abuts tightly against the outer wall of the conductor. Compared with the rigid piercing structure, the piercing structure of this invention has a buffer mechanism to prevent the spikes from excessively piercing and damaging the cable conductor.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-10 This invention provides a technical solution: a quick-change cable connector, comprising: Connector housing 1; Quick-connect mechanism 2 is disposed on connector housing 1 and is used to improve the efficiency of cable connection. Heat dissipation mechanism 3 is located on the top of connector housing 1 and is used to improve the heat dissipation effect of internal components of connector housing 1. Sealing mechanism 4 is disposed on the side of connector housing 1 and is used to seal the outer wall of the connecting cable. The quick-connect mechanism 2 includes a support block 21, which is fixedly installed on the inner wall of the connector housing 1. A conductor 22 is fixedly installed on the support block 21. A frame 23 is fixedly installed on the side of the conductor 22. A limit rod 24 is fixedly installed on the inner wall of the frame 23. A bidirectional lead screw 25 is rotatably connected to the inner wall of the frame 23. A mirror slider 26 is slidably connected to the outer wall of the limit rod 24. The mirror slider 26 is threadedly connected to the outer wall of the bidirectional lead screw 25. A triangular piece 28 is fixedly installed at the bottom of the mirror slider 26. A strip rod 281 is fixedly installed at the bottom of the triangular piece 28. The structure of the side connection of conductor 22 is made of conductive material, and the extension shaft 27 is made of insulating material. After the end of the cable is inserted into the inside of the quick connection mechanism 2, the extension shaft 27 can be rotated manually. Since the threads at both ends of the bidirectional lead screw 25 are opposite, the two mirror sliders 26 can be driven to slide in opposite directions on the outer wall of the limit rod 24, and the strip rod 281 is moved synchronously. This causes the spike 284 to pierce through the outer sheath of the cable and abut against the outer wall of the inner conductor of the cable, so that the cable conductor and conductor 22 are electrically connected, realizing the function of quick connection.

[0020] In a preferred embodiment, a slide rod 282 is slidably connected to the inner wall of the strip rod 281. A connecting block 283 is fixedly installed at the end of the slide rod 282. A spike 284 is fixedly installed on the outer wall of the connecting block 283. An elastic element 285 is fixedly installed on the side of the connecting block 283 away from the spike 284. The end of the elastic element 285 away from the connecting block 283 is fixedly installed on the outer wall of the strip rod 281. Through the connection relationship design between the strip rod 281 and the spike 284, after the spike 284 pierces through the outer sheath of the cable and abuts against the outer wall of the inner conductor of the cable, when the rotating wheel 271 continues to rotate and drive the strip rod 281 to move, the slide rod 282 will slide on the strip rod 281. At the same time, the connecting block 283 will compress the elastic element 285 to avoid the spike 284 from easily piercing the conductor, while tightly abutting against the outer wall of the conductor.

[0021] In a preferred embodiment, an extension shaft 27 is fixedly connected to the end of the bidirectional lead screw 25. The end of the extension shaft 27 away from the bidirectional lead screw 25 extends to the back of the connector housing 1 and is fixedly connected to a rotating wheel 271. An annular component 272 is fixedly installed on the back of the connector housing 1. A rubber ring 273 is fixedly connected to the inner wall of the annular component 272. The inner wall of the rubber ring 273 is movably connected to the outer wall of the extension shaft 27. Through the design of the rotating wheel 271 and the extension shaft 27, the user can operate the rotating wheel 271 to rotate the bidirectional lead screw 25 from the outer wall of the connector housing 1, which is convenient to use. Through the design of the rubber ring 273, the connection between the extension shaft 27 and the connector housing 1 can be sealed, enhancing the waterproof capability of this structure.

[0022] In a preferred embodiment, a fitting seat 221 is fixedly installed on the side of the conductor 22. A T-slot 222 is provided on the fitting seat 221. A T-rod 223 is slidably connected in the inner cavity of the T-slot 222. A contact plate 225 is fixedly installed at the end of the T-rod 223. A metal elastic member 224 is fixedly installed on the outer wall of the T-rod 223. The end of the metal elastic member 224 away from the T-rod 223 is fixedly installed on the inner wall of the fitting seat 221. In use, the end of the cable is inserted into the inner side of the fitting seat 221. The conductor in the cable will squeeze the contact plate 225, causing the contact plate 225 to slide in the T-slot 222 with the help of the T-rod 223. At the same time, the metal elastic member 224 is compressed, so that the end of the cable conductor and the contact plate 225 are tightly fitted together for electrical connection.

[0023] In a preferred embodiment, the quick-connect mechanism 2 further includes a center block 29, which is fixedly installed on the back of the connector housing 1. Track rods 291 are fixedly installed on both sides of the center block 29, and fixing blocks 292 are fixedly installed at the ends of the track rods 291. The fixing blocks 292 are also fixedly installed on the back of the connector housing 1. A protective cover 293 is slidably connected to the outer wall of one set of track rods 291, and a second protective cover 294 is slidably connected to the outer wall of the other set of track rods 291. A rubber rod 295 is fixedly connected to the side of the first protective cover 293. A round hole 296 is opened on the side of the second protective cover 294. In the initial state, the rubber rod 295 is inserted into the inside of the round hole 296, so that the first protective cover 293 and the second protective cover 294 are assembled at the middle block 29, which wraps and protects the two rotating wheels 271, preventing the rotating wheels 271 from being accidentally touched and causing the spikes 284 to loosen. If it is necessary to operate the rotating wheels 271, the first protective cover 293 and the second protective cover 294 can be pushed away from the middle block 29.

[0024] In a preferred embodiment, a viewing window 11 is fixedly installed on the inner wall of the connector housing 1 near the front, and mounting feet 12 are fixedly installed on the outer wall of the connector housing 1. The design of the viewing window 11 makes the inner cavity of the connector housing 1 visible, which is convenient for users to observe the status of the cable connection. The bolts are passed through the mounting feet 12, and then the connector housing 1 can be installed as a whole.

[0025] In a preferred embodiment, the heat dissipation mechanism 3 includes a cover plate 31 and a plastic part 32. The cover plate 31 is movably inserted into the top of the connector housing 1. A plastic pin 33 is fixedly installed on the outer wall of the cover plate 31. The plastic part 32 is fixedly installed on the outer wall of the connector housing 1. The plastic pin 33 is movably inserted into the top of the plastic part 32. When the plastic pin 33 is inserted into the interior of the plastic part 32, the cover plate 31 will be inserted into the top of the connector housing 1, thus completing the installation of the cover plate 31. Conversely, the cover plate 31 can be disassembled to facilitate the maintenance of the components inside the connector housing 1. A rubber strip is connected to the bottom of the cover plate 31, which is used to seal the connection between the cover plate 31 and the connector housing 1.

[0026] In a preferred embodiment, a welding block 34 is fixedly installed on the top of the cover plate 31, and a handle 35 is rotatably connected to the inner wall of the welding block 34. A copper plate 36 is fixedly installed on the inner wall of the cover plate 31, and a heat dissipation fin 37 is fixedly connected to the top of the copper plate 36. In the initial state, the handle 35 is in a horizontal position. If it is necessary to pull out the cover plate 31, the handle 35 can be rotated to a vertical position for easy operation. Through the design of the copper plate 36 and the heat dissipation fin 37, the heat dissipation capacity of the top of the connector housing 1 is improved.

[0027] In a preferred embodiment, the sealing mechanism 4 includes a cable guide 41, which is fixedly connected to the side of the connector housing 1. A support ring 42 is fixedly installed on the inner wall of the cable guide 41, and a rubber ring 43 is fixedly connected to the side of the support ring 42. An inner support ring 44 is fixedly installed on the inner wall of the cable guide 41, and a driven rod 45 is slidably connected to the inner wall of the inner support ring 44. A sliding pressure ring 47 is fixedly installed at the end of the driven rod 45 and is slidably connected to the inner wall of the cable guide 41. An elastic element 46 is fixedly installed on the outer wall of the sliding pressure ring 47, and the end of the elastic element 46 away from the sliding pressure ring 47 is fixedly installed on the outer wall of the inner support ring 44. In use, the end of the cable passes through the inner cavity of the cable guide 41 and is then introduced into the inner cavity of the connector housing 1. The rubber ring 43 is used to seal the connection between the cable and the cable guide 41.

[0028] In a preferred embodiment, a limiting block 451 is rotatably connected to the end of the driven rod 45. The limiting block 451 abuts against the end of the cable guide 41. A protrusion 452 is fixedly installed on the outer wall of the limiting block 451. In the initial state, the limiting block 451 abuts against the cable guide 41. At this time, the elastic element 46 is in a compressed state. After the end of the cable is inserted into the inner cavity of the connector housing 1, the limiting block 451 is rotated from the protrusion 452, causing the limiting block 451 to release from the state of abutting against the end of the cable guide 41. Then, through the elastic force of the elastic element 46, the sliding pressure ring 47 can be driven to move to the left to squeeze the rubber ring 43, causing the rubber ring 43 to undergo elastic deformation and tightly fit against the outer wall of the cable to achieve the sealing function.

[0029] Working principle: In use, the end of the cable is passed through the inner cavity of the cable guide spool 41 and then introduced into the inner cavity of the connector housing 1. This causes the conductor in the cable to press against the contact plate 225, causing the contact plate 225 to slide within the T-slot 222 via the T-shaped rod 223. Simultaneously, the metal elastic element 224 is compressed, resulting in a tight fit between the end of the cable conductor and the contact plate 225 for electrical connection. The limiting block 451 abuts against the cable guide spool 41, at which point the elastic element 46 is in a compressed state. After the end of the cable is inserted into the inner cavity of the connector housing 1, the limiting block 451 is rotated from the protrusion 452, causing the limiting block 451 to release from contact with the cable guide spool 41. The state of the end of the spool 41, and then the elastic force of the second elastic element 46, can drive the sliding pressure ring 47 to move to the left, compressing the second rubber ring 43, causing the second rubber ring 43 to undergo elastic deformation, tightly fitting against the outer wall of the cable, and achieving the sealing function. The extension shaft 27 can be manually rotated. Since the threads at both ends of the bidirectional screw 25 are opposite, it can drive the two mirror sliders 26 to slide in opposite positions on the outer wall of the limit rod 24, synchronously driving the strip rod 281 to move, so that the protrusion 284 pierces through the outer sheath of the cable and abuts against the outer wall of the inner conductor of the cable, so that the cable conductor and conductor 22 are electrically connected, achieving the function of quick connection.
