[0002] Modern cables, as conductors made of one or more conductors and an insulating protective layer, have the function of transmitting electrical energy or information from one place to another, and have gradually become an irreplaceable component in the fields of modern power transmission and information engineering.

[0003] During cable laying, it is often necessary to replace cables due to insufficient cable length. At this time, cable connection devices are used. Currently, the usual method is to twist and connect the conductors of the cable, and then wrap the joint with insulating tape. However, due to the long conductor length and heavy weight, the joint is very easy to break due to the lack of other fixing structures after long-term suspension and swaying. Therefore, there is an urgent need for a connection device for flexible cables to solve the above problems. Utility Model Content

The connecting pipe body is divided into a connecting pipe mother body and a connecting pipe daughter body. The connecting pipe mother body has a connecting pipe inner cavity, and an internal threaded ring is provided on the surface of the connecting pipe inner cavity. The connecting pipe daughter body is provided with a connecting pipe, and an external threaded groove is provided on the outer surface of the connecting pipe. The connecting pipe daughter body is installed into the connecting pipe inner cavity of the connecting pipe mother body through the connecting pipe to achieve connection. The tube body is connected, and fastening components are provided at the tail of both the connecting tube mother body and the connecting tube daughter body. A limiting ring is provided at the installation position of the fastening component, and a limiting thread groove is also opened on the inner side of the limiting ring. The flexible cable body passes through the connecting tube body, and sealing gaskets are provided at two through holes in the connecting tube body. The tail thick block is provided in both the connecting tube mother body and the connecting tube body, and a through hole is left on the tail thick block at the position corresponding to the limiting ring. The fastening component includes a threaded short rod, a spring strip, a small clamping plate, and a connecting clamp. The threaded short rod is installed in the limiting ring, and the bottom of the threaded short rod is assembled in the connecting clamp. A spring strip is connected below the connecting clamp, and a small clamping plate is installed at the bottom of the spring strip.

[0006] Furthermore, the connecting clamp is a hollow, disc-shaped structure that is narrow at both ends and wide in the middle.

[0007] Furthermore, the diameter of the threaded short rod is adapted to the size of the limiting ring, and the limiting thread groove in the limiting ring matches the thread on the threaded short rod.

[0008] Furthermore, both ends of the spring strip are welded to the connecting clamp and the small clamping plate, and the length of the spring strip meets the thickness of the through hole in the thick block at the tail.

The connecting pipe mother body 21 has a connecting pipe inner cavity 5 inside, and an internal threaded ring 6 is provided on the surface of the connecting pipe inner cavity 5. The connecting pipe daughter body 22 is provided with a connecting pipe 8, and an external threaded groove 7 is provided on the outer surface of the connecting pipe 8. The connecting pipe daughter body 22 is installed into the connecting pipe inner cavity 5 of the connecting pipe mother body 21 through the connecting pipe 8 to achieve the connection of the connecting pipe body 2. Fastening components 4 are provided at the tail ends of both the main body 21 and the sub-body 22 of the connecting pipe. A limiting ring 11 is provided at the installation position of the fastening component 4, and a limiting thread groove 12 is also provided on the inner side of the limiting ring 11. The flexible cable body 1 passes through the main body 2 of the connecting pipe, and sealing gaskets 3 are provided at the two through holes of the main body 2 of the connecting pipe. The tail thick block 9 is provided in both the main body 21 and the sub-body 22 of the connecting pipe, and a through hole 10 is left on the tail thick block 9 at the position corresponding to the limiting ring 11. The fastening component 4 includes a threaded short rod 41, a spring strip 42, a small clamp 43, and a connecting clamp 44. The threaded short rod 41 is installed in the limiting ring 11, and the bottom of the threaded short rod 41 is assembled in the connecting clamp 44. The spring strip 42 is connected below the connecting clamp 44, and the small clamp 43 is installed at the bottom of the spring strip 42.

[0020] As the first embodiment of this utility model: the size of the connecting pipe 8 is adapted to the size of the inner cavity 5 of the connecting pipe mother body 21, and the external thread groove 7 on the connecting pipe 8 matches the internal thread ring 6 on the inner cavity 5 of the connecting pipe. This design connects the cable through two sections of connecting pipe that can be joined together, which facilitates disassembly and assembly while also providing a certain degree of protection. The upper and lower ends of the spring strip 42 are welded to the connecting clamp 44 and the small clamp plate 43, and the length of the spring strip 42 meets the thickness of the through hole 10 in the tail block 9. This design Compression by setting spring bar 42 helps to squeeze the cable and prevent the cable from falling out of the connecting pipe body 2. The connecting clamp 44 is a hollow disc structure that is narrow at both ends and wide in the middle. The diameter of the threaded short rod 41 is adapted to the size of the limiting ring 11, and the limiting thread groove 12 in the limiting ring 11 matches the thread on the threaded short rod 41. This design uses the screwing of the threaded short rod 41 in the limiting ring 11 to push the threaded short rod 41 forward, so as to compress the spring bar 42. The structure is simple and easy to adjust and control.

[0021] As a second embodiment of this utility model: When extending the flexible cable, firstly, one end of the flexible cable body 1 is passed through the hole at the rear end of the connecting tube mother body 21, and the other flexible cable is similarly passed through the connecting tube sub-body 22.

In this way, the connecting tube mother body 21 and the connecting tube... The tube body 22 forms a complete connecting tube body 2. Finally, in order to prevent the connected flexible cable body 1 from breaking, the threaded short rod 41 on the connecting tube mother body 12 and the connecting tube body 22 needs to be tightened. The threaded short rod 41 is screwed into the limiting thread groove 12 in the limiting ring 11, so that the threaded short rod 41 will continuously go inward. In this way, the threaded short rod 41 will squeeze the spring strip 42 in the through hole 10. The compression deformation of the spring strip 42 will squeeze the small clamp 43 to limit and fasten the flexible cable, thus preventing the connected flexible cable body 1 from breaking and falling off.
