Patent ID: 8512055

Claim:
A fixing device for a power module, comprising: a supporting rack comprising a base, and a blocking piece formed at a first end of the base for blocking a first end of the power module, the base defining a receiving hole in a second end of the base, a protrusion extending down from the base adjacent to a side of the receiving hole opposite to the blocking piece, a slope facing the receiving hole formed on the protrusion; a latching member comprising a sliding plate slidably mounted to the base, a hook extending up from the sliding plate to detachably engage in a latching hole defined in a second end of the power module, a resilient tongue extending from the sliding plate, an abutting block extending down from a distal end of the tongue; and a resilient member connected between the supporting rack and the latching member, to bias the latching member to make the hook engage in the latching hole, wherein when the latching member is slid relative to the base in a first direction, the hook is detached from the latching hole, the abutting block slidably abuts against the slope to move up away from the base, the tongue is deformed to push up the power module to separate the power module from the supporting rack.
