[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, where there is no conflict, the embodiments and features described in these embodiments can be combined with each other.

[0018] like Figure 1-5The illustration shows a quick connector for a 15kV environmentally friendly integrated node switchgear. This embodiment of the bushing connector includes a bushing body 1, on which are provided a skirt 2, a base 3, a limiting sleeve 4, and a plug protective shell 5. The base 3 is provided with a mounting flange 31 and a limiting tube 32 that matches the limiting sleeve 4. The limiting tube 32 is provided with a limiting ball 321 and a ball groove 322. The limiting sleeve 4 is provided with a clearance groove 40 relative to the inner wall of the ball groove 322. The plug protective shell 5 includes a plug tube 51 and a plug element 52. The plug tube 51 is provided with a limiting groove 53. Permanent magnet pieces 6 are respectively provided on the limiting tube 32 and the limiting sleeve 4. The permanent magnet pieces 6 are used for circumferential rotational alignment of the limiting tube 32 and the limiting sleeve 4.

[0019] In this embodiment, permanent magnet pieces 6 are respectively provided on the limiting sleeve 4 and the limiting tube 32, and the limiting sleeve 4 is provided with a sliding groove 41. The limiting pin 33 extends from the limiting tube 32 and slides within the sliding groove 41. During installation, the limiting pin 33 is pushed in, aligned with the sliding groove 42 of the sliding groove 41. When it is located in the retaining groove 43 at the end of the sliding groove 42, the limiting sleeve 4 will rotate circumferentially due to the magnetic attraction and correction of the permanent magnet pieces 6. Thus, after the limiting sleeve 4 rotates, the limiting pin 33 is exactly located at one end of the retaining groove 43. At this time, the clearance groove 40 on the inner wall of the limiting sleeve 4 is misaligned with the ball groove 322. Therefore, when the limiting sleeve 4 is rotated without external force, the limiting sleeve 4 returns to its original position, and the balls in the ball groove 322 are limited by the inner wall of the limiting sleeve 4 and cannot move outward. As a result, the limiting ball 321 protruding from the ball groove 322 into the limiting groove 53 jams the plug 51 or the connector. Before the limiting sleeve 4 is rotated without external force until the clearance groove 40 is directly opposite the ball groove 322, the plug protective shell 5 and the connector cannot be disassembled. At this time, the state is as follows. Figure 3 As shown, the disassembled state is as follows Figure 4 As shown.

[0020] Furthermore, in this embodiment, the permanent magnet plate 6 is configured to provide a restoring force for the limiting sleeve 4 during disassembly and assembly, and a retaining force for the limiting sleeve 4 during operation. This allows the limiting structure to stably maintain the installation and fixation of the connector or plug protective shell 5. The use of the curved permanent magnet plate 6 also has the advantage of a long service life. Slight external forces will not affect it. Under non-active rotation conditions, accidental external force will quickly reset it, avoiding the problem of the connector popping out.

[0021] As a further feature of the above scheme, the diameter of the limiting bead 321 is matched with that of the ball groove 322, the clearance groove 40 and the limiting groove 53. The minimum diameter of the ball groove 322 is smaller than the maximum diameter of the limiting bead 321. The inner wall of the clearance groove 40 is provided with a gentle slope in the circumferential direction. The purpose of the gentle slope is to allow the limiting bead 321 to move better.

[0022] As a further provision of the above scheme, the sleeve body 1 has a sealing groove 13 and a sealing ring 14 on the end face 12 of the stepped portion 11 at the end of the umbrella skirt portion 2. The stepped portion 11 also has a grounding hole 15. Figure 1 and Figure 2 As shown, in this embodiment, the sleeve connector is installed and fixed on the cabinet plate by mounting flange 31 and bolts. During installation, the corresponding sealing ring 14 is placed in the sealing groove 13 on the end face 12 between the step portion 11 and the cabinet plate, and the bolts are tightened to form an air seal.

[0023] As a further provision of the above scheme, a conductor 62 with a connection hole 61 at the end is also embedded in the sleeve body 1. The conductor 62 passes through both ends of the sleeve body 1 and is exposed outside the sleeve body 1.

[0024] As a further provision of the above solution, the base 3 is also provided with a limiting pin 33, and the limiting sleeve 4 is provided with a sliding groove 41 relative to the limiting pin 33. The sliding groove 41 includes a sliding groove 42 and a retaining groove 43, such as... Figure 1 As shown, in principle, the limiting sleeve 4 of this embodiment maintains axial stability through the permanent magnet piece 6. In this embodiment, a limiting pin 33 and a sliding groove 41 are further provided, which not only form axial limiting at the two end dead points, but also form circumferential limiting when rotating, thereby avoiding problems such as excessive rotation. It can also limit the rotation angle, so that the magnetic adsorption of the permanent magnet piece 6 can achieve the reset of the limiting sleeve 4 without external force.

[0025] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of this utility model and its equivalents, this utility model also intends to include these modifications and variations.
