Lamp socket, backlight assembly having the same and display device having the same
View Patent ↗A lamp socket with a decreased number of elements is presented according to one or more embodiments. The lamp socket in accordance with one embodiment of the present invention includes a power supply member. The power supply member includes a first lamp connecting terminal, a second lamp connecting terminal facing the first lamp connecting terminal and an inverter connecting terminal disposed below the first and second lamp connecting terminals. Upper end portions of the first and second lamp connecting terminals are bent in opposite directions and the first lamp connecting terminal includes a fixing protrusion protruding from an inner surface thereof facing the second lamp connecting terminal.
1. A lamp socket comprising:
a power supply member including:
a first lamp connecting terminal; and
a second lamp connecting terminal facing the first lamp connecting terminal,
wherein upper end portions of the first and second lamp connecting terminals extend away from each other and the first lamp connecting terminal comprises a fixing protrusion protruding from an inner surface thereof facing the second lamp connecting terminal,
wherein the first lamp connecting terminal and the second lamp connecting terminal are configured to be connected to a same lamp electrode,
wherein the fixing protrusion comprises a first curved surface facing downward having a first curvature and a second curved surface facing upwards having a second curvature, and
wherein the second curvature is smaller than the first curvature.
2. The lamp socket of claim 1 , wherein the fixing protrusion includes a bending portion bent from the inner surface of the first lamp connection terminal toward the second lamp connection terminal and a protruding portion extending from an end of the bending portion.
3. The lamp socket of claim 2 , wherein the bending portion forms a corner that points toward the second lamp connection terminal and an edge of the protruding portion opposite to the bending portion faces downwards at an oblique angle.
4. The lamp socket of claim 1 , wherein the fixing protrusion is formed by indenting an area of an outer surface of the first connection terminal toward the inner surface of the first lamp connection terminal,
wherein the area corresponds to the fixing protrusion protruding from an inner surface of the first lamp connecting terminal facing the second lamp connecting terminal.
5. A lamp socket comprising:
a power supply member including:
a first lamp connecting terminal; and
a second lamp connecting terminal facing the first lamp connecting terminal,
wherein upper end portions of the first and second lamp connecting terminals extend away from each other and the first lamp connecting terminal comprises a fixing protrusion protruding from an inner surface thereof facing the second lamp connecting terminal,
wherein the first lamp connecting terminal and the second lamp connecting terminal are configured to be connected to a same lamp electrode,
wherein the fixing protrusion is formed by indenting an area of an outer surface of the first connection terminal toward the inner surface of the first lamp connection terminal,
wherein the area corresponds to the fixing protrusion protruding from an inner surface of the first lamp connecting terminal facing the second lamp connecting terminal,
wherein the fixing protrusion includes a first inclined plane facing downward and a second inclined plane facing upwards, and
wherein a gradient of the first inclined plane is steeper than a gradient of the second inclined plane.
6. A backlight assembly comprising:
a receiving container comprising a bottom plate having a plurality of openings and a sidewall extending from an edge of the bottom plate;
a plurality of lamps on the bottom plate, each of the lamps comprising a lamp body and an electrode portion on an end portion of the lamp body;
a plurality of lamp sockets located in the openings, each of the lamp sockets comprising:
a power supply member comprising:
a first lamp connecting terminal;
a second lamp connecting terminal facing the first lamp connecting terminal; and
an inverter connecting terminal disposed below the first and second lamp connecting terminals; and
a power supply substrate coupled to the inverter connecting terminal to provide a lamp driving voltage to the power supply member,
wherein upper end portions of the first and second lamp connecting terminals extend away from each other and the first lamp connecting terminal includes a fixing protrusion protruding from an inner surface thereof facing the second lamp connecting terminal,
wherein the first lamp connecting terminal and the second lamp connecting terminal are configured to be connected to a same lamp electrode,
wherein the fixing protrusion comprises a first curved surface facing downward having a first curvature and a second curved surface facing upwards having a second curvature, and
wherein the second curvature is smaller than the first curvature.
7. A lamp socket comprising:
a power supply member including:
a first lamp connecting terminal; and
a second lamp connecting terminal facing the first lamp connecting terminal,
wherein upper end portions of the first and second lamp connecting terminals extend away from each other and the first lamp connecting terminal comprises a fixing protrusion protruding from an inner surface thereof facing the second lamp connecting terminal,
wherein the first lamp connecting terminal and the second lamp connecting terminal are configured to be connected to a same lamp electrode,
wherein the fixing protrusion includes a bending portion bent from the inner surface of the first lamp connection terminal toward the second lamp connection terminal and a protruding portion extending from an end of the bending portion,
wherein the fixing protrusion includes a first inclined plane facing downward and a second inclined plane facing upwards, and
wherein a gradient of the first inclined plane is steeper than a gradient of the second inclined plane.
