Backlight assembly
View Patent ↗Provided is a backlight assembly which includes integral power supply sockets and ground sockets, in which the number of parts is reduced in addition to the manufacturing cost. The backlight assembly includes a lamp including a lamp tube and an electrode that protrudes beyond either end of the lamp tube, a power supply socket including a first plate that has a first guide groove through which the electrode is inserted and a plate spring that is disposed on one side of the first plate and fixes the electrode in the first guide groove by pressurizing the electrode, and a bottom chassis containing the lamp and the power supply socket therein, in which the first plate and the plate spring are formed of a conductive material.
1. A backlight assembly comprising:
a lamp having a lamp tube, the lamp tube having an end and an electrode that protrudes in a protruding direction beyond the end of the lamp tube;
a power supply socket configured to receive and retain the electrode, the socket having a first plate spring that is disposed to, on its own, resiliently press against the received and retained electrode in a first direction that is orthogonal to the electrode protruding direction, the socket further having a second plate spring that is disposed to, on its own and when in a relaxed state, cross with the first plate spring and to, on its own and when not in the relaxed state, resiliently press against the received and retained electrode in a second direction opposite to the first direction so that the received and retained electrode is thereby resiliently constrained in the opposed first and second directions; and
a bottom chassis having the lamp and the power supply socket disposed therein,
wherein the first and second plate springs are formed of a conductive material, and
wherein at least one of the first and second plate springs includes a guide groove into which the electrode is inserted when the electrode is received and retained by the socket.
2. The backlight assembly of claim 1 , wherein:
the first and second plate springs are integrally formed as parts of one body from which other parts of the power supply socket are also formed;
wherein the other parts of the power supply socket that are integrally formed in the one body include:
a power-supply-socket bottom plate,
a first plate which protrudes from a first side of the power-supply-socket bottom plate, and
a second plate which protrudes from a second side of the power-supply-socket bottom plate; and
wherein the first and second plate springs integrally and respectively extend from the first and second plates.
3. The backlight assembly of claim 2 , further comprising an inverter guide plate which extends from the power-supply-socket bottom plate.
4. The backlight assembly of claim 2 , wherein:
the second plate spring has the guide groove formed thereon; and
the first plate spring comprises a convex surface which corresponds to the guide groove, and a concave surface which is disposed above the convex surface.
5. The backlight assembly of claim 2 , wherein the second plate spring has the guide groove formed thereon, and the first plate spring is flat.
