[0018] The present invention has the following advantages: The present invention provides a cable terminal connector through improvement. Compared with the same type of equipment, it has the following improvements:

[0019] For the cable terminal connector of the present invention, by providing a connection assembly, a fastening system composed of a nut, a screw rod and a cross plate ensures that the upper cover is tightly closed with the connection box body. When the nut is tightened, the screw rod drives the upper cover to move downward, so that the connection part between the joint plug and the joint sleeve is firmly pressed, further enhancing the overall connection stability, preventing the displacement of the connection components due to external force impact, ensuring the long-term stable operation of the cable, effectively blocking impurities such as dust and water vapor from invading the inside of the connection box body, avoiding problems such as short circuit or corrosion caused by the accumulation of impurities, and prolonging the service life of the connector.

[0020] For the cable terminal connector of the present invention, by providing a clamping assembly, the upper clamping plate and the lower clamping plate not only fix the cable by the initial clamping force, but also its linkage structure plays a key role. An adaptive adjustment system similar to a robotic arm is formed among the first side plate, the second side plate, the third side plate and each rotating shaft. When the cable is displaced by force, the sliding of the upper clamping plate relative to the square plug plate will be quickly transmitted to the whole system, and each side plate rotates flexibly through the rotating shaft, automatically adjusting the clamping angle and strength, and always maintaining a firm clamping of the cable. It is like an intelligent clamping device, greatly reducing the risk of cable loosening and ensuring the uninterrupted transmission of electricity or signals.

[0021] The cable terminal connector described in the present invention is provided with a pressing component, which is beneficial to adjusting the clamping force of the lower clamping plate and the upper clamping plate on the cable, improving the use effect of the connector, and enabling the connection positions of the two cables to be in a relaxed state, avoiding the problem of loosening at the cable docking position due to pulling.

The threaded rod 57 is rotationally connected to the rectangular sliding plate 55 through the bearing 58.

[0049] Through improvement, the present invention provides a cable terminal connector, and its working principle is as follows;

[0050] First, when it is necessary to connect the end of the first cable 6 and the end of the second cable 7, the first cable 6 and the second cable 7 are respectively inserted into the interior of the connection box 1 through the sealing sleeve 38. The joint sleeve 32 is sleeved on the end of the first cable 6, and the joint plug 33 is sleeved on the end of the second cable 7. By inserting the joint plug 33 into the interior of the joint sleeve 32, the connection of the first cable 6 and the second cable 7 is realized. The connected first cable 6 and second cable 7 are respectively placed in the arc-shaped grooves formed on the surface of the corresponding lower clamping blocks 311. The upper cover 2 is placed on the upper surface of the connection box 1, and the screw 35 is inserted into the interior of the longitudinal jack 31, and the rubber rectangular frame 313 is inserted into the interior of the frame-shaped groove 312. By rotating the nut 34, the upper cover 2 can be moved towards the connection box 1. As the upper cover 2 moves, the two upper clamping blocks 39 move synchronously, so that the first cable 6 and the second cable 7 are respectively pressed into the arc-shaped grooves formed on the bottom surface of the upper clamping blocks 39. As the nut 34 continues to rotate, the acting force exerted on the cables by the upper clamping blocks 39 and the lower clamping blocks 311 can be increased until the upper cover 2 and the connection box 1 are closely fitted, thereby realizing the position fixation of the connection box 1 and the upper cover 2, and the effect of fixing the cables can be ensured under the action of the arc-shaped pressing ring 310;

[0051] When the upper cover 2 is installed on the connection box 1, the rubber rectangular frame 313 is inserted into the interior of the frame-shaped groove 312, which can further improve the sealing performance of the connection between the connection box 1 and the upper cover 2. The first cable 6 and the second cable 7 are respectively inserted into the interior of the connection box 1 from the interior of the sealing sleeve 38, which can further ensure the sealing performance of the connection between the first cable 6 and the second cable 7;

[0052] During the process of inserting the first cable 6 and the second cable 7 into the interior of the connection box 1 respectively, the first cable 6 and the second cable 7 respectively penetrate through the upper clamping plate 41 and the lower clamping plate 44. By rotating the threaded rod 57, the rectangular sliding plate 55 can slide inside the outer sleeve 53 under the action of the thread. The movement of the rectangular sliding plate 55 drives the built-in square plate 52 to move synchronously through the spring 54. When the hemispherical block 51 is in contact with the end of the lower clamping plate 44, as the built-in square plate 52 moves, the hemispherical block 51 can exert a force on the lower clamping plate 44, and then the cables are clamped by the upper clamping plate 41 and the lower clamping plate 44. As the threaded rod 57 continues to rotate, the compressed distance of the spring 54 continuously increases, and then the force exerted by the hemispherical block 51 on the lower clamping plate 44 continuously increases, which is beneficial to adjusting the clamping force of the lower clamping plate 44 and the upper clamping plate 41 on the cables, improving the use effect of this connector, and enabling the connection positions of the two cables to be in a relaxed state, avoiding the problem of loosening caused by pulling at the cable docking position;

[0053] When the cable is in use, the cable pulls the upper clamping plate 41 and the lower clamping plate 44, so that the upper clamping plate 41 has a force to slide on the surface of the square plug plate 43, that is, the upper clamping plate 41 and the lower clamping plate 44 pull the second side plate 49, so as to exert a force on the third rotating shaft 413. The third rotating shaft 413 pulls the first side plate 48 under the force, so that the first side plate 48 can rotate on the surface of the auxiliary rotating shaft 47, thereby increasing the clamping force of the upper clamping plate 41 and the lower clamping plate 44 on the cable, and avoiding the situation that the cable slides and pulls the cable docking position;

[0054] The connection design between the connector plug-in 33 and the connector sleeve 32 is exquisite in that the inner wall of the connector sleeve 32 has a special thread structure. The thread is not an ordinary uniform thread, but a variable pitch design. The pitch is slightly larger near the entrance end, which is convenient for the connector plug-in 33 to be quickly inserted and initially positioned. As the insertion depth increases, the pitch gradually decreases, so that a stronger fastening force can be provided in the later stage of connection, ensuring that the connector plug-in 33 is tightly connected to the connector sleeve 32, effectively preventing the connection from loosening due to cable shaking or external force pulling, and greatly improving the stability of the electrical connection, which is crucial for ensuring continuous and stable transmission of signals;

[0055] When considering environmental factors, the sealing design of the connection box 1 and the upper cover 2 has a deeper level of consideration. In addition to the cooperation between the rubber rectangular frame 313 and the frame groove 312, the surface of the connection box 1 is additionally provided with a circle of micro-sealed airbags at the edge in contact with the upper cover 2. When the nut 34 is tightened to press the upper cover 2 downward, the airbag is squeezed and deformed, and fits tightly in the gap between the upper cover 2 and the connection box 1, forming a double sealing protection. Even in a high humidity environment, such as electrical facilities at the seaside or rainforest areas, it can effectively block the intrusion of water vapor, avoid rust and corrosion of internal metal parts, extend the service life of the connector, and ensure long-term stable operation;

[0056] When the cable is subjected to a sudden external force impact, such as strong wind causing the cable to swing, the upper clamping plate 41 and the lower clamping plate 44 not only rely on the initial clamping force to fix the cable, but also their linkage structure plays a key role. The first side plate 48, the second side plate 49, the third side plate 410 and the shafts form an adaptive adjustment system similar to a mechanical arm. When the cable is displaced by force, the sliding of the upper clamping plate 41 relative to the square plug plate 43 will be quickly transmitted to the entire system. The side plates rotate flexibly through the shafts to automatically adjust the clamping angle and force, and always maintain a stable clamping of the cable, just like an intelligent clamping device, which greatly reduces the risk of cable loosening and ensures uninterrupted power or signal transmission.

[0057] In addition to providing the basic elastic clamping force, the spring 54 in the extrusion assembly 5 also has the function of buffering and energy absorption. In daily scenarios of slight cable vibration or gentle pulling, the spring 54 utilizes its own elastic deformation to absorb energy, preventing minute vibrations from being transmitted to the connection part and causing wear. When encountering a relatively large external force impact, such as an accidental collision during construction, the spring 54 can be instantly compressed to buffer most of the impact force, protecting the internal core wires of the cable and the connection components from damage, and ensuring the reliable performance of the connector in a complex and changeable usage environment.
