[0024] Please refer to Figure 1-Figure 2 , Figure 1 The present invention is a schematic diagram of the structure of a detachable high-voltage ring network box busbar connecting sleeve in an embodiment of the present invention. The detachable high-voltage ring network box busbar connecting sleeve comprises an outer sleeve 10, an inner sleeve 20 and a connector 30. The outer sleeve 10 is connected to the inner sleeve 20 through the connector 30. One end of the connector 30 is embedded in the outer sleeve 10, and the other end of the connector 30 is embedded in the inner sleeve 20. The inner sleeve 20 is fixed on the air box 40 on all sides. In actual use, the inner sleeve 20 is first installed on the air box 40, and then one end of the connector 30 is connected to the inner sleeve 20. Then, the outer sleeve 10 is connected to the other end of the connector 30 to achieve preliminary assembly. In actual use, when the cable connected to the end of the outer sleeve 10 is burned out, the outer sleeve 10 is generally damaged. At this time, we only need to bring a new outer sleeve 10 to the site for replacement, which avoids the back and forth transportation of the air box 40.

[0025] In some preferred embodiments, a first conductive rod 11 is provided in the outer sleeve 10, and a second conductive rod 21 is provided in the inner sleeve 20. The first conductive rod 11 and the second conductive rod 21 are connected and conducted via a conductive component 50. The conductive component 50 is disposed in the middle of the connector 30. In actual use, the first conductive rod 11 is disposed at the axis of the outer sleeve 10, the second conductive rod 21 is also disposed at the axis of the inner sleeve 20, and the conductive component 50 is also disposed at the axis of the connector 30.

The first threaded connection hole 111 is used to connect to the cable outside the air box 40, and the second threaded connection hole 211 is used to connect to the cable inside the air box 40.

[0027] In some preferred embodiments, the first conductive rod 11 is provided with a first contact head 112 at one end close to the conductive component 50, and the second conductive rod 21 is provided with a second contact head 212 at one end close to the conductive component 50, and the first contact head 112 and the second contact head 212 are respectively connected to two ends of the conductive component 50.

[0028] In certain preferred embodiments, the conductive component 50 includes a first card connector 51, a conductive tile 52 and a second card connector 53. The first card connector 51 and the second card connector 53 have the same conductive structure and are respectively arranged at both ends of the conductive tile 52. The first card connector 51 is used to be connected with the first contact head 112, and the second card connector 53 is used to be connected with the second contact head 212. There is a gap 511 between the upper side wall of the first card connector 51 and the inner wall of the connector 30, and there is a gap 531 between the lower side wall of the second card connector 53 and the inner wall of the connector 30. In actual use, there is a conductive gap in the middle of the conductive tile 52 to facilitate circuit heat dissipation.

[0029] In some preferred embodiments, when the first contact head 112 contacts the first clamping connector 51 and is clamped into the first clamping connector 51, the gap 511 first decreases and then recovers;

[0030] When the second contact head 212 contacts the second clamping connector 53 and is clamped into the second clamping connector 53 , the gap 531 first becomes smaller and then recovers.

[0031] In certain preferred embodiments, the connector 30 is a hollow cylindrical structure, and the thickness of the side wall of the connector 30 gradually decreases from the middle to the two ends. The inner wall of the outer sleeve 10 is provided with a first embedding groove 13, and the inner wall of the inner sleeve 20 is provided with a second embedding groove 23. The first embedding groove 13 and the second embedding groove 23 can be respectively used for embedding the two ends of the connector 30.

[0032] In other preferred embodiments, a chassis 12 is provided at the bottom end of the outer sleeve 10, a through hole 121 is provided on the annular surface of the chassis 12, and a screw hole 22 is provided at a corresponding position of the inner sleeve 20, and the outer sleeve 10 is fixed to the inner sleeve 20 by a screw.
