Patent ID: 8608365

Claim:
A backlight fixing device, comprising: a base plate comprising: a first side, a second side connected to the first side, a third side opposite to the first side, and a fourth side opposite to the second side and connected to the third side, the first through fourth sides being connected to each other from beginning to end in that order, the first side and the second side defining two adjacent sides of the base plate, the third side and the fourth side defining another two adjacent sides of the base plate, an L-shaped bar formed on an upper surface of the base plate protruding from edges of the two adjacent sides of the base plate, a first guiding groove and a second guiding groove defined in the upper surface of the base plate, which correspondingly extend perpendicularly from the other two adjacent sides of the base plate towards a central area of the base plate, and a recess defined in the upper surface of the base plate adjacent to the second guiding groove, a first elongated guiding element perpendicular to the second guiding groove being formed in the recess, and the first guiding element being a guiding rail, a first slidable unit movably attached to the base plate and being movable along the first guiding groove, a second slidable unit movably attached to base plate and being movable along the second guiding groove, and an interface module movably received in the recess and being movable along the first guiding element, the interface module comprising a third slidable unit and a power socket, and the third slidable unit comprising a sliding groove defined in an underside surface thereof for engagably receiving the first guiding element, wherein the first slidable unit, the second slidable unit and the L-shaped bar form a receiving space for accommodating a backlight module, and the interface module is configured for removably electrically connecting to the backlight module.
