[0019] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments.

[0020] Embodiment: see Figures 1-6This utility model discloses a copper cable connection structure, comprising two copper cables 1, with connecting tubes 2 at their proximal ends. The connecting tubes 2 are sleeved with the outer sheath of the copper cables 1, and the outer wall of the connecting tubes 2 is threaded. The distal ends of the two connecting tubes 2 are flared structures with cross-shaped openings longitudinally. Nuts 3 are threaded onto the outer side of the connecting tubes 2. A connector 5 is installed on one end of the connecting tube 2, with an adapter groove on its outer wall. Extension blocks are located on both sides of the other end of the connector 5, with a through hole in the center of each extension block. An adapter 4 and a rotating sleeve 8 are respectively located on the other end of the connector 5. One end of the adapter 4 is rotatably connected to the rotating sleeve 8. A cylindrical boss is located in the center of the inner wall of the rotating sleeve 8, and the rotating sleeve 8 and the connector 5 are rotatably engaged via the adapter groove and the cylindrical boss. Extension blocks are located on both sides of the adapter 4. A threaded through hole is provided in the middle of the block, and the other end of the adapter 4 is connected to another connecting pipe 2; the adapter 4 is provided with screws 6 on both sides, and the screws 6 pass through the extension blocks on both sides of the connector 5 and are threadedly connected to the extension blocks on both sides of the adapter 4; aluminum tubes 7 are installed longitudinally inside the adapter 4 and the connector 5, and the aluminum tubes 7 are sleeved at the connection points of the two copper cables 1; the aluminum tubes 7 facilitate the sleeved connection of the copper cables 1, and the flared structure and nut 3 at the rear end of the connecting pipe 2 facilitate the locking of the copper cables 1 sleeved inside the connecting pipe 2; the adapter 4, connector 5, and rotating sleeve 8 facilitate the formation of an outer shell to cover and protect the connection points of the copper cables 1; the screws 6 and the extension blocks facilitate the fixing and limiting of the position of the adapter 4 and the connector 5 to prevent the rotating sleeve 8 from rotating and causing the adapter 4 and the connector 5 to detach.
