The upper end face of the ceramic base 1 has an upper groove 11, and the lower end face of the ceramic base 1 has a lower groove 12. A connecting cylinder is embedded in the lower groove 12. The connecting cylinder consists of a conductive block 21, an insulating ring 22, and a conductive cylinder 23. The upper end face of the conductive block 21 has a threaded hole 20. The outer wall of the conductive block 21 is fixed to the inner wall of the insulating ring 22, and the outer wall of the insulating ring 22 is fixed to the inner wall of the conductive block 21. The inner wall of the conductive cylinder 23 is fixed, and the inner wall of the conductive cylinder 23 is provided with a connecting thread that mates with the halogen lamp. The first through hole connects the upper groove 11 and the lower groove 12. The connecting bolt 25 passes through the first through hole and is screwed into the threaded hole 20. The head of the connecting bolt 25 is located in the upper groove 11. The head of the connecting bolt 25 is fixed with a first terminal 26. The second through hole connects the upper groove 11 and the lower groove 12. The conductive cylinder 23 is connected to a conductive post 27. The conductive post 27 passes through the second through hole and extends into the upper groove 11. A second terminal 28 is installed on the conductive post 27. The second terminal 28 is located in the upper groove 11.

[0017] The head of the connecting bolt 25 abuts against the inner bottom wall of the upper groove 11, and the upper end face of the conductive block 21 abuts against the inner top wall of the lower groove 12.
