[0023] The effect achieved by the entire embodiment 1 is that when using the cable connector to connect the cables, the insulation layers of the two cables are peeled off to expose the cable cores, which are then inserted from the openings on both sides of the main connector 1, and then the second bolts 5 are screwed. The rotation of the second bolts 5 can drive the second clamping plates 6 to move toward the cable cores, and the two cable cores can be clamped and fixed to the inner side of the main connector 1 through the second clamping plates 6 on both sides, completing the butt fixation of the cables. After completing the butt fixation of the cable cores, the exposed position of the cable core corresponding to the main connector 1 is wrapped with a thermoplastic tube, and then the insulation layer positions of the two cables can be clamped and fixed by using the auxiliary connectors 301 on both sides, and screwing the first bolts 303 can drive the first clamping plates 304 to move toward the cable direction, and the first clamping plates 304 on both sides can The cable is clamped and fixed at the inner side of the auxiliary connector 301. At this time, the state of the two cables is that the docking cable core position is clamped at the inner side of the main connector 1, and the position close to the outer side of the docking position is clamped and fixed at the inner side of the auxiliary connector 301. When one side of the cable is dragged and pulled during the use of the cable, since the auxiliary connectors 301 on both sides are supported by the middle slide bar 204, and the slide bar 204 can slide freely on the inner wall of the sliding sleeve 203, the drag force on one side of the cable will be transmitted to the position of the auxiliary connector 301 on the other side through the connection of the slide bar 204, so that the cable on the other side is also subjected to the drag force. At this time, the force can be unloaded for the two cables, avoiding the loosening of the connector position when the single-side cable is dragged and pulled, causing a safety accident, and playing a better safety protection role for the cables of new energy vehicles.

[0024] Embodiment 2, as Figure 1-Figure 4 As shown, a buffer plate 207 is fixedly connected to the outer surface of the slide rod 204, and multiple dampers 205 are evenly fixedly connected to the outer surface of the buffer plate 207 close to the fixed ring 201. The outer surfaces of the multiple dampers 205 are all sleeved with springs 206, and the end faces of the dampers 205 and the springs 206 are fixedly connected to the outer surface of the fixed ring 201.

[0025] The effect achieved by the entire embodiment 2 is that when one side of the cable is pulled and dragged after the cables are connected, the buffer plate 207 on the other side will move toward the fixed ring 201 driven by the slide bar 204, and the buffer plate 207 will compress the damper 205 and the spring 206 to contract when moving. The coordinated use of the damper 205 and the spring 206 can buffer and reduce shock on the movement of the buffer plate 207, so that the movement amplitude of the slide bar 204 is smaller, thereby reducing the drag force on the cable, thereby providing better protection for the cable.

[0026] Working principle: When using the cable connector to connect the cables, the insulation layers of the two cables are stripped off to reveal the cable cores, which are then inserted from the openings on both sides of the main connector 1, and then the second bolts 5 are screwed. The rotation of the second bolts 5 can drive the second clamping plates 6 to move toward the cable cores, and the two cable cores can be clamped and fixed on the inner side of the main connector 1 through the second clamping plates 6 on both sides, completing the docking and fixation of the cables. After the docking and fixation of the cable cores are completed, the exposed positions of the cable cores corresponding to the main connector 1 are wrapped with thermoplastic tubes, and then the auxiliary connectors 301 on both sides are used to clamp and fix the insulation layer positions of the two cables respectively, and screwing the first bolt 303 can drive the first clamping plates 304 to move toward the cable direction, and the cables can be clamped and fixed on the inner side of the auxiliary connector 301 through the first clamping plates 304 on both sides. At this time, the two cables are in the state that the docking cable core position is clamped on the inner side of the main connector 1, and the position close to the outer side of the docking position is clamped and fixed on the inner side of the auxiliary connector 301. When the cables are used, one side of the cable is dragged and pulled When the cable is pulled, since the auxiliary connectors 301 on both sides are supported by the middle sliding rod 204, and the sliding rod 204 can slide freely on the inner wall of the sliding sleeve 203, the dragging force on one side of the cable will be transmitted to the auxiliary connector 301 on the other side through the connection of the sliding rod 204, so that the cable on the other side is also subjected to the dragging force. At this time, the force can be unloaded for the two cables, avoiding the safety accident caused by the loosening of the connector position when the single-side cable is dragged and pulled, and playing a better safety protection role for the cables of new energy vehicles. When one side of the cable is pulled and dragged after the cables are connected, the buffer plate 207 on the other side will move toward the fixed ring 201 driven by the slide bar 204, and the buffer plate 207 will compress the damper 205 and the spring 206 to contract when moving. The damper 205 and the spring 206 work together to buffer and reduce shock on the movement of the buffer plate 207, so that the movement range of the slide bar 204 is smaller, thereby reducing the drag force on the cable and providing better protection for the cable.
