[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] See attached documentFigures 1-5 A wind power cable connection assembly that is easy to install includes a first terminal 1 and a second terminal 2 that are nested and rotated together. The first terminal 1 and the second terminal 2 adopt an inner and outer sleeve nesting structure. The first terminal 1 and the second terminal 2 are both nested by the inner and outer sleeves. There are also two inverted and correspondingly plugged junction boxes 3 between the inner sleeves. The inverted symmetrical structure forces physical alignment and avoids the problem of phase reversal when operating by beginners. One end of the junction box 3 is connected to a connector 31 at the upper part and a plug groove 32 for accommodating the connector 31 at the lower part. The other end is also provided with a groove 33 for accommodating the cable. The junction box 3 is also provided with a countersunk hole, and the cable is fixed in the groove 33 by bolts.

[0024] The first terminal 1 adopts an inner and outer sleeve nesting structure, specifically, the inner and outer sleeves of the first terminal 1 include a first inner sleeve 13 and a first outer sleeve 11. The first inner sleeve 13 extends into the first outer sleeve 11 and one end extends circumferentially, so that the first inner sleeve 13 is rotatably disposed in the first flange 12, and a first through groove 14 for accommodating the junction box 3 is also provided on the first inner sleeve 13.

[0025] The first outer cylinder 11 has a connecting cavity 15, and the second outer cylinder 21 has a protrusion 25 around its edge. The connecting cavity 15 is used to accommodate the protrusion 25, and at least two connecting blocks 16 are connected to the inner wall of the connecting cavity 15. The connecting blocks 16 are used to restrict the protrusion 25. The interlocking of the connecting blocks 16 and the protrusion 25 enables blind insertion alignment and quick positioning. The first outer cylinder 11 has a first flange 12 connected to its side wall, and the second outer cylinder 21 has a second flange 22 connected to its side wall. The two working together can be screwed on more conveniently.

[0026] The second terminal 2 also adopts an inner and outer sleeve nesting. The inner and outer sleeves of the second terminal 2 include a second inner cylinder 23 and a second outer cylinder 21. The second inner cylinder 23 extends into the second outer cylinder 21 and one end extends circumferentially, so that the first inner cylinder 13 is rotatably disposed in the first flange 12. A second through groove 24 for accommodating the junction box 3 is also provided on the second inner cylinder 23.

[0027] The inner sleeve is made up of two half-covers, and the cable is clamped by bolts.
