Patent ID: 8830682

Claim:
An electronic device comprising: an enclosure configured to house a circuit board, the enclosure having a first opening of an upper portion thereof and a second opening of a lower portion thereof; a side-plate configured to extend horizontally along a side surface of the enclosure, the side plate including a first horizontal guide having a non-operating position and an operating position, a second horizontal guide having a non-operating position and an operating position, and a vertical guide extending vertically from the operating position of the first horizontal guide; a pivot lever configured to extend horizontally along the side plate, the pivot lever having a fulcrum, an action point and a force point, the fulcrum being engaged with the second horizontal guide and being movable between the non-operating position and operating position of the second horizontal guide in a horizontal direction, the action point being engaged with the first horizontal guide and being movable between the non-operating position and operating position of the first horizontal guide in a horizontal direction, the force point being positioned at one end portion of the pivot lever; a lifter configured to be movable upward and downward along the vertical guide, the lifter being engaged with the action point of the pivot lever on the occasion that the action point of the pivot lever is moved to the operating position of the first horizontal guide and the fulcrum of the pivot lever is moved to the operating position of the second horizontal guide; a first connector configured to be disposed at an upper portion of the lifter and to be connected to the circuit board, the first connector moving upward to protrude from the first opening of the enclosure upon the pivot lever being engaged with the lifter and being pivoted from a horizontal position to move up the lifter; and a second connector configured to be disposed to expose at the second opening of the enclosure and to be connected to the circuit board, the second connector being connected to a first connector that is protruded from an enclosure of another electronic device, which has a structure the same as that of the electronic device, disposed immediately below the electronic device.
