The conductive carrier plate 1 is made of an aluminum connecting plate, so that the conductive performance is better and the weight is light. The drainage wire clamps also adopt aluminum wire clamps with better conductivity. The back plate 2 is made of an iron connecting plate which has enough strength as an external fixed part.

In this embodiment, each of the first and second current leading clips 3 and 4 includes an integrally formed carrier connecting portion 341 and a cable connecting portion 342, and the carrier connecting portion 341 is fixedly connected to the surface of the conductive carrier 1.

The front and the back of the conductive carrier plate 1 define the outer ring area of wire clamp connection, the first drainage wire clamp 3 and the second drainage wire clamp 4 are respectively arranged on the wire clamp connection outer ring area of the surface where the first drainage wire clamp 3 and the second drainage wire clamp 4 are arranged in a surrounding mode, and the first drainage wire clamp 3 and the second drainage wire clamp 4 are arranged in a staggered mode. Namely, 4 first drainage wire clamps 3 are arranged, which is equivalent to being uniformly arranged around the front surface of the conductive carrier plate 1 at intervals; the number of the second current lead clamps 4 is 6, which is equivalent to that the second current lead clamps are uniformly arranged around the back surface of the conductive carrier plate 1 at intervals. The staggered arrangement means that the first drainage wire clamp 3 and the second drainage wire clamp 4 which are close to each other do not have any overlapping part at the front side and the rear side of the conductive carrier plate 1, so that the mutual interference is prevented, and the installation and the fixation are convenient. The first lead clip 3 can be larger in size than the second lead clip 4, as can also be seen from the illustration.
