[0022] By adopting the above technical scheme, the two clamping pieces in the connecting component 43 are used to clamp and connect the two ends of the two wire cores 2, and then the threaded barrel 49 is rotated to control the limit sleeve 47 to one side, and then the two pressing blocks 45 are squeezed to the opposite side, so that the cable 1 is firmly clamped and fixed by the two pressing blocks 45, so as to achieve rapid splicing of the two cables 1, and the integral insulating connecting barrel 3 is used to improve the protection of the splicing point, thereby increasing the service life of the splicing point and reducing the risk of using the spliced ​​cables.

[0023] Example 2: Please refer to Figure 1-3On the basis of the first embodiment, a connecting column 41 is fixedly installed inside the insulating connecting cylinder 3, and circular grooves 42 are provided on both sides of the connecting column 41. One end of the wire core 2 passes through and extends into the circular groove 42. A connecting component 43 located inside the circular groove 42 and used to connect the two wire cores 2 is provided inside the connecting column 41. The connecting component 43 includes a conductor and two clamping pieces. The two clamping pieces are fixedly connected to the two ends of the conductor respectively. The two clamping pieces are respectively located inside the circular grooves 42 on the left and right sides. The clamping pieces clamp the wire core 2, which is convenient for connecting the two corresponding wire cores 2. The wire core 2 is connected, and mounting grooves 44 are provided on the top and bottom of the insulating connecting tube 3. Pressure blocks 45 for clamping the cable 1 are slidably installed inside the two mounting grooves 44. Limiting components 46 for limiting the upward and downward movement of the pressure blocks 45 are provided inside the two mounting grooves 44. The two limiting components 46 include a limiting rod and a through groove. The through groove is provided inside the pressure block 45. The limiting rod is fixedly installed between the left and right side walls of the inner cavity of the mounting groove 44. The outer surface of the limiting rod is slidably connected to the inner wall of the through groove to limit the movement trajectory of the pressure block 45.

[0024] Among them, the number of installation grooves 44, pressure blocks 45, and limit assemblies 46 are four, and the four installation grooves 44, pressure blocks 45, and limit assemblies 46 are symmetrically distributed on the insulating connecting tube 3, so as to facilitate fixing the two cables 1 inserted into the insulating connecting tube 3.

[0025] By adopting the above technical solution, the cable 1 is inserted into one side of the insulating connecting tube 3, so that the core 2 is inserted into the inside of the circular groove 42 on the connecting column 41, and the core 2 is clamped by the clamping piece in the connecting component 43, and then the two pressing blocks 45 are controlled to squeeze toward the opposite side until the two pressing blocks 45 firmly clamp the cable 1, and then the above steps are repeated to insert another cable 1 into one side of the insulating connecting tube 3, so as to achieve rapid splicing of the two cables 1.

[0026] In the implementation of this example, a limiting sleeve 47 for limiting the movement of the two pressure blocks 45 is slidably installed on the outer surface of the insulating connecting tube 3. The limiting sleeve 47 includes an annular tube and a limiting strip. The limiting strip is fixedly installed on the rear side wall of the inner cavity of the annular passage. A limiting groove is provided on the back of the insulating connecting tube 3.

[0027] There are two limit sleeves 47 , two bearings 48 and two threaded cylinders 49 , which are symmetrically distributed on the outer surface of the insulating connecting cylinder 3 , so as to facilitate the control of the normal movement of the four pressing blocks 45 .

[0028] By adopting the above technical solution, the threaded cylinder 49 is rotated, thereby controlling the limiting sleeve 47 connected to the inner thread of the threaded cylinder 49 to move to one side, so that the limiting sleeve 47 squeezes the two pressing blocks 45 to the opposite side.

[0029] The working principle of the above embodiment is:

[0030] When using the wires and cables that can be spliced ​​with each other, the cable 1 is inserted into one side of the insulating connecting tube 3, so that the wire core 2 is inserted into the inside of the circular groove 42 on the connecting column 41, and the wire core 2 is clamped by the clamping piece in the connecting component 43, and the threaded barrel 49 is rotated to control the limiting sleeve 47 with the internal thread connection of the threaded barrel 49 to move to one side, so that the limiting sleeve 47 squeezes the two pressing blocks 45 to the opposite side until the two pressing blocks 45 firmly clamp the cable 1, and then repeat the above steps to insert another cable 1 into one side of the insulating connecting tube 3, so as to quickly splice the two cables 1.
