[0028] Example

[0029] like Figs. 1-3 As shown, a cable connector 1 includes two cables 1 and a connecting tube 2, with pressing tubes 3 fixed at both ends of the connecting tube 2, a fixed tube 4 sleeved on the outer surface of the connecting tube 2, the fixed tube 4 and the connecting tube 2 are slidably connected, the fixed tube 4 is threadedly connected to the pressing tube 3, and a protective structure is provided on the outside of the fixed tube 4. The protective structure includes a first outer tube 6, a second outer tube 7 and a rubber sheet 9. The first outer tube 6 and the second outer tube 7 are sleeved on the outside of the fixed tube 4, the right end of the first outer tube 6 and the left end of the second outer tube 7 are threadedly connected, and the left end of the first outer tube 6 and the right end of the second outer tube 7 are both provided with a first through hole 8 for the cable 1 to pass through.

[0030] It is worth noting that the two cables 1 are connected by the provided connecting tube 2, and the two cables 1 are respectively inserted into the connecting tube 2 from the left and right ends to achieve connection. The provided pressing tube 3 and the fixed tube 4 work together to restrict the cable 1 to prevent the cable 1 from falling out of the connecting tube 2. The provided protective structure protects the connection between the two cables 1 and enhances the service life of the connector in harsh environments. The first outer tube 6 and the second outer tube 7 are arranged on the outermost side to protect the connecting tube 2 and the cable 1.

[0031] In some feasible embodiments, a conductive block 5 is provided in the connecting tube 2, and the two ends of the conductive block 5 have an arc-shaped groove structure, which increases the contact area between the conductive block 5 and the conductor in the cable 1, so that workers do not need to align the conductors in the two cables 1 for connection when making connections. They only need to insert the conductor of the cable 1 into the connecting tube 2 so that the conductor contacts the conductive block 5.

[0032] In some feasible embodiments, the pressing tube 3 is a variable diameter structure, the diameter of the pressing tube 3 at one end close to the connecting tube 2 is smaller than the diameter at the end away from the connecting tube 2, and the diameter of the pressing tube 3 at one end away from the connecting tube 2 is larger than the diameter of the cable 1, so as to facilitate the insertion of the cable 1 into the connecting tube 2.

[0033] In some feasible embodiments, the wall thickness of the pressing tube 3 at the end away from the connecting tube 2 is greater than the wall thickness near the connecting tube 2. When the fixing tube 4 is rotated to completely cover the pressing tube 3, the inner cavity of the pressing tube 3 is a variable diameter structure, and its diameter near the end of the connecting tube 2 is greater than the diameter away from the connecting tube 2, and the diameter of the end with a smaller diameter is smaller than the diameter of the cable, which can fix the cable.

[0034] In some feasible embodiments, the compression tube 3 includes several compression plates, which are arranged obliquely at the openings at both ends of the connecting tube 2. A gap is provided between adjacent compression plates, and each compression plate is provided with a section of thread. The threads on these compression plates form a complete thread that matches the fixed tube 4. When the fixed tube 4 is screwed onto the outside of the compression tube 3, the gaps between adjacent compression plates disappear, making the diameter of the compression tube 3 away from the connecting tube 2 smaller than the diameter of the cable 1, thereby securing the cable 1.

[0035] In some feasible embodiments, the diameter of the first through hole 8 is larger than the diameter of the cable 1 , so that the cable 1 can pass through the first through hole 8 smoothly.

[0036] In some feasible embodiments, a rubber sheet 9 is disposed within the first outer tube 6 and fixedly disposed at the left end of the inner cavity of the first outer tube 6. A second through-hole is defined in the rubber sheet 9. A rubber sheet 9 is disposed within the second outer tube 7 and fixedly disposed at the left end of the inner cavity of the second outer tube 7. A second through-hole is defined in the rubber sheet 9. The diameter of the second through-hole is smaller than the diameter of the cable 1. Due to the elasticity of the rubber, when the cable 1 passes through the second through-hole, the sidewalls of the second through-hole will closely adhere to the outer surface of the cable 1, thereby preventing water from entering the connector.

[0037] During installation, first put the first outer tube 6 and the second outer tube 7 on the two cables 1 respectively, with the connecting end of the first outer tube 6 and the second outer tube 7 close to the connecting end of the cable 1, then remove a portion of the insulation layer on the outer surface of the cable 1 to expose the conductor of the cable 1, and insert the two cables 1 through the pressing tube 3 from both ends of the connecting tube 2 so that the conductor of the cable 1 contacts the conductive block 5, rotate the fixed tubes 4 at the left and right ends respectively, so that the fixed tubes 4 completely cover the pressing tube 3, and fix the cable 1, and finally rotate the first outer tube 6 and the second outer tube 7 to connect the first outer tube 6 and the second outer tube 7 into one.

[0038] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
