The welding terminal sleeve 2 contains welding terminals 4, and the adapter copper busbar sleeve 3 contains adapter copper busbars 5 connected to the welding terminals 4. The adapter copper busbar sleeve 3 contains adapter copper busbar insertion slots 6 and screw mounting holes 7. The front end of the adapter copper busbar insertion slot 6 has an elastic hook 8, and the rear end of the adapter copper busbar insertion slot 6 has a mounting platform 9. The adapter copper busbar 5 is inserted into the adapter copper busbar insertion slot 6, and its surface has a first barb 10 connected to the elastic hook 8 and a second barb 11 connected to the mounting platform 9. Screws 12 are installed in the screw mounting holes 7, and the welding terminals 4 and the adapter copper busbar 5 are connected by the screws 12. There are two welding terminals 4 and two adapter copper busbars 5. By placing the screws inside the adapter copper busbar sleeve, the L-shaped metal housing 1 eliminates the need for openings and caps, resulting in a smaller size and better waterproof performance. During assembly, the adapter copper busbar 5 is simply inserted into the adapter copper busbar insertion slot 6.

[0018] Preferably, the adapter copper busbar sleeve 3 is connected to the first slot 14 on the side wall of the L-shaped metal housing 1 via first elastic buckles 13 on both sides. The front end of the welding terminal sleeve 2 is inserted into the adapter copper busbar sleeve 3, and its side is connected to the second slot 16 on the side wall of the L-shaped metal housing 1 via second elastic buckles 15. This structure enables a quick connection between the adapter copper busbar sleeve 3 and the welding terminal sleeve 2 and the L-shaped metal housing 1.

[0019] Preferably, the rear end of the welding terminal sheath 2 is fitted with a shielding outer ring 17, and the shielding outer ring 17 contains a shielding inner ring 18. The front end of the shielding outer ring 17 is provided with circumferentially arranged contact pieces 19, and the contact pieces 19 are provided with protrusions 20 that contact the L-shaped metal outer shell 1. When the cable is welded to the welding terminal 4, the shielding inner ring 18 and the shielding outer ring 17 are fitted onto the front end of the cable and pressed tightly.

[0020] Preferably, a nut 21 is embedded at the front end of the welding terminal sleeve 2, and the front end of the screw 12 is connected to the nut 21 to improve the connection strength of the screw 12.

[0021] Preferably, the L-shaped metal casing 1 has an outer sheath 22 at its front end, the adapter copper busbar sheath 3 has a first sealing ring 23 that seals with the outer sheath 22, and the L-shaped metal casing 1 has a second sealing ring 25 and a tail cap 26 at its rear end. This improves the product's waterproof performance.

[0022] Preferably, the front end of the L-shaped metal outer casing 1 is fitted with a threaded sleeve 24, which is connected to the outer sheath 22 by inserting a screw into the threaded sleeve 24. This structure allows the outer sheath 22 to be replaced.

[0023] Preferably, the adapter copper busbar sleeve 3 is provided with a positioning groove 27, and the adapter copper busbar 5 is provided with a positioning protrusion 28 that positions and cooperates with the positioning groove 27. This improves the stability of the adapter copper busbar 5 after installation.
