[0014] Such as Figure 1As shown in the figure, this embodiment provides a lockable electrical connection conversion device, which includes a main body housing 1, a support cover 3, a positioning plate 6, a support front cover 9, and a conversion circuit board. At least three columns of first square holes 2 are evenly arranged on the back of the main body housing 1; a through hole is provided at the top of the support cover 3, and a locking spindle 5 is arranged in the through hole. The support cover 3 is fixedly arranged on the back of the main body housing 1, and at least three columns of second square holes 4 are evenly arranged on the support cover 3. The second square holes 4 correspond to the first square holes 2 one by one; the positioning plate 6 is arranged between the main body housing 1 and the support cover 3, and the positioning plate 6 is fixedly connected to the main body housing 1. At least three columns of third square holes 7 are arranged on the positioning plate 6, and the third square holes 7 correspond to the first square holes 2 one by one; the support front cover 9 is arranged on the front of the main body housing 1, and the support front cover 9 is fixedly connected to the main body housing 1; the conversion circuit board is arranged between the support front cover 9 and the main body housing 1. At least three columns of U-shaped copper clips 8 are arranged on the conversion circuit board. The U-shaped copper clips 8 pass through the first square holes 2 and the third square holes 7. The U-shaped copper clips 8 pass through the first square holes 2 arranged on the back of the main body housing 1 and the third square holes 7 arranged on the positioning plate 6 to reach the second square holes 4 arranged on the support cover. When the locking spindle 5 is tightened, the U-shaped copper clips 8 open and close under the drive of the positioning plate 6; when the locking spindle 5 is loosened, the U-shaped copper clips 8 open under the action of their own elasticity, and at the same time drive the positioning plate 6 to return to its original position.
