[0019] EMBODIMENT

[0020] The high-altitude power cable connector described in the embodiment, as shown in the figure, comprises two left and right distributed connecting pipes 1, in production, the two connecting pipes 1 can be set to be in left and right communication state, in addition, the inner side end of the connecting pipe 1 can also be set to be closed, when the inner side end of the two is in closed state, the inner side end of one of the connecting pipes 1 is fixed with a butt joint block 7, and the inner side end of the other connecting pipe 1 is provided with a butt joint groove for butt joint of the butt joint block 7. The butt joint block 7 is in the shape of a circular truncated cone, which facilitates the butt joint of the two connecting pipes 1. The connecting pipe 1 and the clamping plate 5 are made of conductive materials, such as copper, iron and the like. When the two connecting pipes 1 are connected to the connecting end of the cable respectively, the cable needs to be energized by using the conductive performance of the connecting pipe 1. Figs. 1 to 3

[0021] The inside of the connecting pipe 1 is in the structure of wide outside and narrow inside, and the inside of the connecting pipe 1 is in the structure of a circular truncated cone with wide outside and narrow inside. In the embodiment, the two connecting pipes 1 are distributed left and right, one end close to the two connecting pipes 1 is the inner side, and the end far away from the two connecting pipes 1 is the outer side. Therefore, when the inner hole diameter of the connecting pipe 1 is in the shape of a circular truncated cone, the hole diameter of the outer side end of the connecting pipe 1 is larger than that of the inner side end.

[0022] ​The connecting tube 1 is equipped with two clamping plates 5 for holding the cable. The two clamping plates 5 are mutually clamping and fit together, and the outer surface of the clamping plates 5 is in contact with the inner wall of the connecting tube 1. In use, the clamping plates 5 can slide along the inside of the connecting tube 1.

[0023] A slider 4 is fixed on the clamping plate 5. A groove is provided on the connecting tube 1 for the slider 4 to slide along its length. One side of the slider 4 passes independently through the groove and is located on the outside of the connecting tube 1. The slider 4 slides along the groove, pushing the clamping plate 5 to slide along the inside of the connecting tube 1. In use, as the two clamping plates 5 slide inward along the inner wall of the connecting tube 1, the inside of the connecting tube 1 narrows, and the two push rings 3 clamp the cable connection end more tightly as they move inward.

[0024] The clamping end of the clamping plate 5 is provided with teeth 6 for engaging the cable; in use, the teeth 6 on the clamping end face of the clamping plate 5 are used to further clamp and fix the cable, making the connection between the connecting tube 1 and the cable more stable.

[0025] Each of the two connecting tubes 1 is independently fitted with a connecting sleeve 2, and the two connecting sleeves 2 are connected to each other. A push ring 3 is fixed on the connecting sleeve 2 to push the slider 4 to slide inward. The push ring 3 is independently fitted on the connecting tube 1.

[0026] The two connecting sleeves 2 are connected to each other by threads. The outer side wall of the connecting sleeve 2 on the right side has an external thread, and the inner side wall of the connecting sleeve 2 on the left side has an internal thread that engages with the internal thread. In use, the two connecting sleeves 2 rotate relative to each other to achieve connection. The connecting sleeve 2 and the push ring 3 are integrally formed.

[0027] In practical use, the cable connection ends are first inserted into the two connecting tubes 1, ensuring that the clamp 5 is positioned on the outer side of the connecting tube 1. Then, the two connecting sleeves 2 are rotated to connect them. As they rotate, the connecting sleeve 2 on the right side continuously retracts towards the connecting sleeve 2 on the left side, shortening the tubes. At this point, the two connecting tubes 1 are aligned, and their overall length remains unchanged. As the connecting sleeves 2 shorten, the push ring 3 pushes the slider 4 towards the inner end of the connecting tube 1, which in turn moves the clamp 5 towards the inner end of the connecting tube 1. As the clamp 5 moves towards the inner end of the connecting tube 1, the clamping of the cable becomes increasingly tight, until the operator feels a very secure connection and the connecting sleeve 2 is difficult to rotate. This indicates that the clamp 5 has firmly clamped the cable, thus simultaneously connecting the connecting tube 1 to the cable connection end and connecting the two connecting tubes 1 together, improving the efficiency of cable connection. Furthermore, the connection of the two connecting tubes 1 via the connecting sleeves 2 eliminates the need to rotate the entire cable during rotation, making installation more convenient.
