Description

Technical Field

[0001] This utility model relates to the field of power connection technology, specifically to a power connection fitting. Background Technology

[0002] This type of electrical connection hardware is used for converting and connecting insulated conductors, bare conductors, aluminum stranded wires, copper core aluminum stranded wires, steel stranded wires, and copper conductors at non-load-bearing positions in high, medium, and low voltage lines. This hardware can withstand significant tensile forces during operation and ensures good electrical contact, making it widely used in power grid transmission lines. According to application number CN222016170U, this electrical connection hardware features a connection component where, after the wire is placed inside the collar, turning a lever moves it within the clamp, simultaneously moving a locking block on the side of a bearing. The locking block enters the collar through a sliding opening on its side, compressing and fixing the wire within the collar, thus achieving a secure connection and preventing loosening at the wire joint. However, the shape of one end of the locking block only allows for fixing cables of one diameter; it is unsuitable for fixing cables of other diameters, resulting in limited applicability.

[0015] Example 1 Please see Figures 1 to 4 This utility model provides a technical solution: an electrical connection fitting, including a mounting base 1, with two guide blocks 2 slidably connected inside the mounting base 1. A positioning block 4 is inserted inside each guide block 2. The top of each positioning block 4 extends above the guide block 2 and is fixedly connected to a positioning disc 5. A rotating shaft is rotatably connected to the top of each positioning disc 5, and a top plate 6 is fixedly connected to the top of each rotating shaft. A first limiting ring 7 is fixedly connected to the top of each top plate 6. A second limiting ring 8 is hinged to one end of each first limiting ring 7. A second fixing block 10 is fixedly connected to one side of each second limiting ring 8. Each side is fixedly connected to a first fixing block 9. Each top plate 6 is fixedly connected to a side plate 12. Each side plate 12 is threadedly connected to a threaded rod 13. One end of each threaded rod 13 passes through the side plate 12 and extends to the outside of the side plate 12. Each threaded rod 13 is connected to a moving block 14 through a bearing. Each moving block 14 has a limiting block 15 inside. Each limiting block 15 has a clamping column 18 fixedly connected to one side. Each side of the first limiting ring 7 has a through groove 22. Each side of the mounting base 1 is fixedly connected to a mounting plate 23. The mounting plate 23 is fixedly fixed to the place where it needs to be fixed by using fixing components (such as screws) through the mounting holes on the mounting plate 23.

[0016] Bolts 16 are inserted inside each movable block 14. The two ends of the bolts 16 extend to both sides of the movable block 14. Nuts 17 are threaded to the tail ends of the bolts 16. The bolts 16 and nuts 17 are used to fix the first fixed block 9 and the second fixed block 10, thereby fixing the second limiting ring 8 and the first limiting ring 7.

[0017] One end of the top plate 6 is fixedly connected to an arc-shaped block 19, which is located on one side of the positioning disk 5. The arc-shaped block 19 is threaded with a third screw 20 inside. Several positioning holes 21 are opened on the outer side of the positioning disk 5. One end of the third screw 20 is inserted into the corresponding positioning hole 21, and the other end of the third screw 20 extends to the outer side of the arc-shaped block 19. The arc-shaped block 19, the top plate 6, the first limiting ring 7, and the second limiting ring 8 are fixed by screwing one end of the third screw 20 into the positioning hole 21.

[0018] The guide block 2 is threaded with a first screw 3. One end of the first screw 3 extends into the interior of the positioning block 4, and the other end of the first screw 3 extends to the outside of the guide block 2. The guide block 2 and the positioning block 4 are fixed by the first screw 3.

[0019] The second fixing block 10 is threaded with a second screw 11 inside. The bottom end of the second screw 11 extends into the first fixing block 9 and is threaded into the first fixing block 9. The second fixing block 10 and the first fixing block 9, as well as the second limiting ring 8 and the first limiting ring 7 are fixed by the second screw 11.

[0020] Example 2 Please see Figure 1 and Figure 2 This utility model provides a technical solution: the bottom ends of the movable blocks 14 all extend into the guide grooves opened at the top of the top plate 6 and are slidably connected to the inside of the guide grooves. One end of the guide blocks 2 all extends to the outside of the mounting base 1. The top of the guide blocks 2 is fixedly connected to the limit blocks 24. The limit blocks 24 are threaded with the fourth screws 25. Several positioning grooves 26 are opened on one side of the mounting base 1. By moving the guide blocks 2, the position of the positioning blocks 4 is adjusted. After the position of the positioning blocks 4 is adjusted, one end of the fourth screws 25 is screwed into the corresponding positioning grooves 26 to limit and fix the limit blocks 24, guide blocks 2, positioning blocks 4, positioning disk 5, first limit ring 7 and second limit ring 8.

[0021] When it is necessary to fix cables at different angles, unscrew one end of the third screw 20 out of the positioning hole 21, then rotate the top plate 6 so that the top plate 6 drives the rotating shaft to rotate, causing the arc block 19 to move along the outside of the positioning plate 5. When the positions of the first limiting ring 7 and the second limiting ring 8 are adjusted to a suitable angle, screw one end of the third screw 20 into the positioning hole 21 to limit the angle of the first limiting ring 7 and the second limiting ring 8. Then, according to the diameter of the cable, replace the clamping post 18. Take a clamping post 18 with a suitable shape, put the limiting block 15 at one end of the clamping post 18 into the moving block 14, and then pass one end of the bolt 16 through the limiting block 15. The cable extends to the outside of the movable block 14, and then the nut 17 is screwed onto the outside of the bolt 16 to fix the limiting block 15 and the clamping post 18 onto the movable block 14. Then the outside of the cable is placed inside the first limiting ring 7, and then the second limiting ring 8 is closed so that the second fixing block 10 is located above the first fixing block 9. Then one end of the second screw 11 is screwed into the inside of the first fixing block 9 to fix the second limiting ring 8 and the first limiting ring 7. Then the threaded rod 13 is rotated so that the threaded rod 13 pushes the movable block 14, the limiting block 15 and the clamping post 18 to move, so that the clamping post 18 passes through the through groove 22 and enters the inside of the first limiting ring 7 to fix the cable. Then, if it is necessary to replace the structure above the positioning block 4, unscrew one end of the first screw 3 out of the positioning block 4, pull the positioning block 4 out of the guide block 2, insert the bottom end of the other positioning block 4 into the guide block 2, screw one end of the first screw 3 into the positioning block 4, and fix the positioning block 4.
