Patent ID: 7883231

Claim:
A backlight assembly comprising: a lamp having a lamp tube and an electrode that protrudes beyond either end of the lamp tube; a power supply socket having a first plate that includes an electrode entrapping first guide groove through which the electrode is inserted for anti-removal entrapment at an entrapping end portion of the first guide groove, 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 toward the entrapping end portion of the first guide groove; and a bottom chassis having the lamp and the power supply socket therein, wherein the first plate and the plate spring are formed of a conductive material, and wherein the electrode of the lamp can be introduced along a first directed axis during insertion so as to pass between and in contact with the plate spring and a mid-insertion edge portion of the first guide groove during insertion, where the plate spring presses toward a second directed axis different from the first directed axis against the electrode during insertion so as to urge the electrode against the mid-insertion edge portion and where at the end of insertion the electrode is urged by the plate spring into entrapped contact with the entrapping end portion of the first guide groove, said entrapping end portion being offset in the direction of the second directed axis from the mid-insertion edge portion of the first guide groove so as to prevent the electrode from being moved out of the entrapping end portion by movement in only along the first directed axis.
