[0015] As Figures 1-4 shown: a cable line connecting device, including connecting cylinder 1, connecting cylinder 1 left and right two ends are open and are flared, the left and right two ends of connecting cylinder 1 are all fixed with sleeve pad sleeve 2, pad sleeve 2 is away from the outer wall of one end of connecting cylinder 1 and is sleeved with hoop 3, the inner side of connecting cylinder 1 has insulating pad 4, insulating pad 4 is tubular, the outer wall of both ends of insulating pad 4 is fixedly connected with the inner wall of both ends of connecting cylinder 1 respectively, the end of two cables 5 is inserted into two pad sleeves 2 respectively, the cable 5 includes cable core 6, the cable core 6 of both sides is inserted into insulating pad 4 and overlaps, a plurality of pressing plates 7 are arranged between the outer side of insulating pad 4 and the inner side of connecting cylinder 1, the pressing plate 7 is arc-shaped, the pressing plate 7 is evenly staggered around the insulating pad 4, the outer wall of the middle part of the pressing plate 7 is vertically connected with the inner end of the threaded rod 9, the outer end of the threaded rod 9 penetrates the outer wall of the connecting cylinder 1, the threaded rod 9 is screwed with the connecting cylinder 1, the outer end of the threaded rod 9 is fixedly connected with the knob 10, the guide rod 8 is arranged on both sides of the threaded rod 9, the guide rod 8 is parallel with the threaded rod 9, the inner end of the guide rod 8 is fixedly connected with the outer wall of the pressing plate 7, the outer end of the guide rod 8 penetrates the outer wall of the connecting cylinder 1, and the guide rod 8 is slidably connected with the connecting cylinder 1.

[0016] First, ensure that the two groups of cables 5 to be connected have been stripped of the outer skin, exposing the internal cable core 6.

[0017] Insert the two groups of cables 5 from the openings on the left and right ends of the connecting cylinder 1, and preliminarily fix and guide them through the pad sleeves 2. At this time, the cable cores 6 will pass through the pad sleeves 2 into the interior of the connecting cylinder 1 and slide along the inner wall of the insulating pad 4 until the two groups of cable cores 6 overlap inside the insulating pad 4.

[0018] Next, by manually rotating the knob 10, the knob 10 drives the threaded rod 9 to rotate on the outer wall of the connecting cylinder 1 and advance inwardly. Since the threaded rod 9 is vertically connected to the middle part of the pressing plate 7, the advancement of the threaded rod 9 will push the pressing plate 7 to move towards the insulating pad 4, thereby clamping the staggered cable cores 6. At the same time, the guide rod 8 plays a role in guiding and stabilizing the movement track of the pressing plate 7, ensuring that the pressing plate 7 remains stable during the movement and does not deviate from the predetermined path. With the continuous rotation and advancement of the threaded rod 9, the pressing plate 7 gradually clamps the cable cores 6 until the desired connection tightness is achieved.

[0019] When the cable cores 6 are clamped, the clamp 3 can be further fixed on the outer wall of the pad cover 2 to enhance the stability and dustproof and waterproof performance of the entire connecting device.
