The photoelectric transmission unit is composed of two electric units (3) and a first butterfly unit (2). The two electric units (3) are respectively located in the corresponding second cavity (13). The first butterfly unit (2) is located in the first cavity (12) formed between the second cavity wall (14) on the right side of the left protective layer and the second cavity wall (14) on the left side of the right protective layer.
