[0025] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include the three-dimensional spatial dimensions of length, width, and depth.

[0026] Referring to Figures 1-4, this embodiment of the invention provides a sleeve-type conical fixing and limiting stranded wire clamp. This device includes an inner conical sleeve 1, with an overall conical cylindrical structure and a through hole in the center for the stranded wire to pass through. It consists of an inlet portion 11 and a mounting portion 12; wherein the inlet portion 11 and the mounting portion 12 are fixedly connected, and both are used for the stranded wire to pass through. An outer conical sleeve 2, also with an overall conical cylindrical structure and a through hole in the center for the stranded wire to pass through, consists of a rotating portion 21 and a tightening portion 22. The rotating portion 21 and the tightening portion 22 are fixedly connected, and the rotating portion 21 is sleeved on the outside of the mounting portion 12. By rotating, the rotating portion 21 moves axially along the mounting portion 12, thereby causing the tightening portion 22 to squeeze the inlet portion 11, achieving the fixing and limiting of the stranded wire, preventing the stranded wire from unraveling, deforming, or becoming difficult to bend.

[0027] Specifically, the inlet 11 includes a conical opening 111 for the stranded wire to enter, and the conical opening 111 has several conical pressure strips 112 due to the opening of the extrusion port 113.

[0028] The inner wall of the tapered pressure strip 112 is provided with striped marks to increase friction with the stranded wire, and the extrusion port 113 is a trapezoidal groove. The tapered pressure strip 112 retracts towards the center under force.

[0029] Furthermore, the mounting part 12 includes a mounting tube 121 fixedly connected to one side of the tapered opening 111, and an external threaded groove 122 is provided on the outer wall of the mounting tube 121.

[0030] Furthermore, the mounting tube 121 is a cylindrical structure with a through hole in the middle for the stranded wire to pass through, and the external threaded groove 122 is used to fit the outer conical sleeve 2 to fix the stranded wire.

[0031] Furthermore, the inner conical sleeve 1 also includes an outlet 13 on one side of the mounting tube 121 fixedly connected to the mounting part 12. The outlet 13 includes a connecting tube 131, which is a cylindrical structure with a through hole in the middle for the stranded wire to pass through. An external threaded groove 122 is also provided on the outer wall to limit the entire inner conical sleeve 1.

[0032] Furthermore, the rotating part 21 includes a rotating tube 211 that is rotatably sleeved on the mounting tube 121. The inner wall of the rotating tube 211 is provided with an internal thread groove 212 that is adapted to the external thread groove 122, so that the outer conical sleeve 2 moves on the inner conical sleeve 1.

[0033] Furthermore, the tightening part 22 includes a tightening port 221 fixedly connected to one side of the rotating part 21. The tightening port 221 has a conical structure. A flat port 222 is fixedly connected at the smallest diameter of the tightening port 221. The flat port 222 has a cylindrical structure. The flat port 222 and the tightening port 221 have a through hole in the middle for the stranded wire to pass through. When the outer conical sleeve 2 moves on the inner conical sleeve 1, the rotating tank will first contact the conical pressure bar 112 on the inlet part 11. Then, the tightening port 221 will gradually apply pressure to the conical pressure bar 112 to tighten it towards the center. Finally, the stranded wire will be stably pressed in the flat port 222.

[0034] Furthermore, the outlet 13 of the inner conical sleeve 1 is connected to an installation mechanism 3. The installation mechanism 3 includes a V-bolt 31, a first hexagonal nut 32, and a second hexagonal nut 33. The inner conical sleeve 1 moves into the middle position of the V-bolt 31 through the outlet 13, and then the first hexagonal nut 32 is installed in the outlet 13 through the space in the middle of the V-bolt 31. Then, the second hexagonal thread is installed through the external thread groove 122 on the installation part 12 so that the inner conical sleeve 1 is installed on the V-bolt 31.

[0035] Furthermore, the V-bolt 31 includes a limiting plate 311 that allows the outlet portion 13 to pass through. Connecting lugs 312 are fixedly connected to both sides of the limiting plate 311. The connecting lugs 312 facilitate the connection of the V-bolt 31 to the power structure after the inner conical sleeve 1 is installed.

[0036] During operation, the inner conical sleeve 1 consists of an inlet 11, an installation part 12, and an outlet 13. The inlet 11 has a conical opening 111 for the wire to enter. Due to the opening of the extrusion port 113, the conical opening 111 has several conical pressure strips 112. The inner wall of the conical pressure strips 112 has striped grooves. The installation part 12 includes a cylindrical installation tube 121 fixedly connected to one side of the conical opening 111. The outer wall of the installation tube 121 has an external threaded groove 122. The outlet 13 includes a cylindrical connecting tube 131 fixedly connected to one side of the installation tube 121. The outer wall of the connecting tube 131 also has a threaded groove 122. The outer conical sleeve 2 has an external threaded groove 122; it consists of a rotating part 21 and a tightening part 22. The rotating part 21 includes a rotating tube 211 with an internal threaded groove 212 on its inner wall that matches the external threaded groove 122 of the mounting tube 121. The tightening part 22 includes a conical tightening opening 221 fixedly connected to one side of the rotating part 21. A cylindrical flat opening 222 is fixedly connected at the smallest diameter of the tightening opening 221. Each corresponding part of the inner conical sleeve 1 and the outer conical sleeve 2 has a through hole for the stranded wire to pass through. Then, the stranded wire is passed through the flat opening 222 and the tightening opening of the outer conical sleeve 2 in sequence. 221. The through hole of the rotating tube 211, and the through holes of the inlet 11 tapered opening 111, the mounting tube 121, and the outlet 13 connecting tube 131 of the inner tapered sleeve 1, complete the initial threading of the stranded wire; then, the second hexagonal nut 33 is installed on the external thread groove 122 of the mounting tube 121 of the mounting part 12. Then, the rotating part 21 of the outer tapered sleeve 2 is rotated. Since the internal thread groove 212 of the inner wall of the rotating tube 211 is adapted to the external thread groove 122 of the outer wall of the mounting tube 121, the rotating part 21 will move axially along the mounting tube 121 of the mounting part 12 during the rotation, thereby... The tightening part 22 moves synchronously. During the movement, the rotating tube 211 first contacts the conical pressure strip 112 on the inlet 11 of the inner conical sleeve 1. As it continues to rotate, the tightening port 221 of the tightening part 22 gradually applies pressure to the conical pressure strip 112. Because the conical pressure strip 112 is restricted by the structure of the trapezoidal groove, it will retract towards the center. The striped marks on the inner wall of the conical pressure strip 112 can increase the friction with the stranded wire. Finally, the flat port 222 of the tightening part 22 will stably press the stranded wire, thereby fixing and limiting the stranded wire and effectively preventing the stranded wire from becoming unraveled, distorted, or difficult to bend.

[0037] After the stranded wire is fixed, the clamp is connected to the power structure. The outlet 13 of the inner conical sleeve 1 is inserted into the limiting plate 311 of the V-bolt 31, so that the outlet 13 moves to the middle position of the V-bolt 31. The first hexagonal nut 32 is installed on the external thread groove 122 of the connecting tube 131 of the outlet 13 through the space in the middle of the V-bolt 31. With the cooperation of the first hexagonal nut 32 and the second hexagonal nut 33, the inner conical sleeve 1 is firmly installed on the V-bolt 31. Finally, with the help of the connecting lugs 312 on both sides of the limiting plate 311 of the V-bolt 31, the entire insert-type conical fixed limiting stranded wire clamp is connected to the power structure, completing the overall installation and fixing work.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
