  • Circuit board fixing device
    Patent number: 8164914
    Abstract: The present invention discloses a circuit board fixing device for fixing a circuit board. The device comprises a chassis for supporting the circuit board, at least one first hook setting on the supporting surface, and at least one second hook setting on the supporting surface. The first hook has a first contact surface for clamping a first type circuit board on the supporting surface. A first distance is between the first contact surface and the supporting surface. Additionally, the second hook has a second contact surface for clamping a second type circuit board on the supporting surface. A second distance is between the second contact surface and the supporting surface. The thickness of the first type circuit board is thicker than that of the second type circuit board, and the first distance is larger than the second distance.
