However, since the thickness of the circuit boards used in the circuit boards are different according to different current frequencies, and the heights of various components on the circuit boards are different, the gaps between the circuit boards are different during the stacking process, which easily causes mutual collision and damage, affecting the stacking and storage function of the circuit boards.

[0014] The present invention provides a stacked multi-layer circuit board having the following beneficial effects:
[0015] (1) The stacked multilayer circuit board is directly inserted into the partition plate. The circuit board can be pressed upward by the arc surface of the pressure ball on the partition plate to make it slide. When the circuit board is about to be fully inserted, the circuit board can push the push plate and the insertion rod to slide in the direction of the card plate. The triangular card block can be pushed into the inside of the insertion rod through its own triangular inclined surface. When the insertion rod drives the triangular card block through the clamping hole, the triangular card block is clamped outside the clamping hole through its own triangular vertical surface. Finally, the partition plate can be suitable for stacking and storing components of different thicknesses or different heights of the circuit board.
[0016] (2) The stacked multi-layer circuit board is provided with a pressure reduction device. When the circuit board is inserted into the partition plate, the push rod can push the arc-shaped push plate to slide through its own triangular inclined surface, and the arc-shaped push plate can compress the elastic element to generate elastic force. The elastic force here can offset and reduce the downward pressure of the partition plate on the circuit board, thereby reducing the downward pressure generated by the multi-layer stacking of the circuit board on the partition plate and reducing the pressure loss.
[0017] (3) The stacked multilayer circuit board is provided with a fixed rod and a ball. When the top rod is pushed upward by the telescopic plate, the top rod contacts the outside of the ball, and the ball slides through the outer wall of the top rod to produce mutual friction. The ball then generates friction vibration with the through hole on the top rod, thereby driving the top rod to vibrate. The provision of the through hole can improve the ventilation capacity of the circuit boards when they are stacked and stored.
[0018] (4) The stacked multi-layer circuit board is provided with an auxiliary pressing device. When the circuit board is about to be fully inserted, the push plate drives the insertion rod to slide in the direction of the card plate. The sliding of the extrusion plate can push the cylindrical rod to slide downward through its own arc surface. The cylindrical rod is pushed downward by its own arc surface to drive the pressing rod to slide downward. The pressing rod can drive the pressing ball to perform auxiliary pressing and supporting operations on the circuit board.
[0019] (5) In the stacked multi-layer circuit board, the arc-shaped sliding of the pressing rod can drive the pressing ball to slide toward the center of the pressure ball, so that the pressing ball can form a downward gripping force on the circuit board to move and slide toward the center of the pressure ball. When the circuit board is fully inserted, the cylindrical rod will be squeezed by the squeezing plate, so that the cylindrical rod can drive the pressing rod and the pressing ball to continue to press on the top of the circuit board, thereby increasing the supporting force of the contact part between the circuit board and the outside of the pressure ball, thereby improving the stability of the circuit board after it is fully inserted.
