Arrangement of two secondary circuit boards within an electronic device

An electronic device, comprising:

• a housing;
• and
• an electronic assembly disposed inside the housing;
• wherein the electronic assembly comprises:
• a first electronic component with a first secondary circuit board;
• a second electronic component with a second secondary circuit board;
• and
• a primary circuit board;
• wherein the first secondary circuit board is electrically connected to the primary circuit board by a first electrical connector, interlayer space capable of accommodating the second secondary circuit board is formed between the first secondary circuit board and the primary circuit board, a portion of the second secondary circuit board that enters the interlayer space overlaps the first secondary circuit board and is electrically connected to the primary circuit board with a second electrical connector, and in an overlapping direction, the second secondary circuit board is located between the first secondary circuit board and the primary circuit board, the first electrical connector is located between the first secondary circuit board and the primary circuit board, and the second electrical connector is located between the second secondary circuit board and the primary circuit board;
• wherein an operating height of the first electrical connector is greater than an operating height of the second electrical connector;
• and
• wherein the electronic assembly further comprises:
• a positioning mechanism configured to position the first secondary circuit board and the second secondary circuit board, wherein the positioning mechanism comprises at least one positioning column perpendicular to the first secondary circuit board and the second secondary circuit board, and the first secondary circuit board is provided with a first positioning hole or a first positioning groove for the positioning column to pass through, and the second secondary circuit board is provided with a second positioning hole or a second positioning groove for the positioning column to pass through.
