Description

  The present invention relates to a backlight fluorescent lamp fixing unit, in particular, a fluorescent lamp (CCFL) used in a backlight of a large liquid crystal television (LCD TV) is simply connected to an electric wire, and a large amount of fluorescent lamps are fixed by a simple operation. The present invention relates to an integrated backlight fluorescent lamp fixing unit that can be reliably connected electrically.

  In general, LCD TVs are required to have high brightness and use a lot of fluorescent lamps. However, generally, an external electrode fluorescent lamp (EEFL) is used for a liquid crystal display device of 37 inches or less. A cold cathode fluorescent lamp (CCFL: Cold Cathode Fluorescent Lamp) is used for a large-sized liquid crystal display device of 37 inches or more.

  In order to connect such a cold cathode fluorescent lamp to an electric wire, a fluorescent lamp fixing unit is used. A fluorescent lamp fixing unit according to the prior art has been previously filed as “backlight lamp fixing socket (Patent Document 1)”.

However, the backlight lamp fixing socket that has been previously applied has a problem that only one fluorescent lamp can be fixed. That is, a large-sized liquid crystal display device having a size of 37 inches or more is provided with several tens of fluorescent lamps. However, in the conventional lamp fixing socket, each fluorescent lamp must be fixed. There is a problem that a complicated operation of connecting the lamp to the socket and fixing each socket to the frame of the display device is required.

  With the above-described configuration of the present invention, the plurality of fluorescent lamps mounted on the liquid crystal display device can be fixed to the frame of the liquid crystal display device by a simple process.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings, and the same parts are denoted by the same reference numerals. 1 and 2 are a perspective view and a partial sectional perspective view of an integrated backlight fluorescent lamp fixing unit according to an embodiment of the present invention, and FIG. 3 is an exploded perspective view. 4 is a cross-sectional view taken along the line A-A 'in FIG. 1, and FIG. 5 is a cross-sectional view taken along the line B-B' in FIG.

  As shown in the drawing, an integrated backlight fluorescent lamp fixing unit according to the present invention shown by reference numeral 10 includes a conductive base 30 and a lid 20.

  The conductive base 30 is formed by cutting a metal plate material and bending it in multiple stages. For example, as shown in FIG. 3, a pair of side frames 33 and a base plate 31 are formed by bending the ends of both sides in the longitudinal direction of a rectangular metal plate material into a “U” shape. A projection groove 35 is formed on the side surface of the lid 20 so as to be spaced apart at a constant interval so that a projection 28 of the lid 20 to be described later is attached.

  As shown in FIG. 3, a pair of contact terminals 40 are formed on the base plate 31 at regular intervals. The contact terminal 40 is preferably formed by cutting and bending the base plate 31, but may be separately manufactured and welded to the base plate 31 as necessary.

  As shown in the partially enlarged view of FIG. 3, the contact terminal 40 branches into a pair of guide plates 45, a contact groove 41 is formed between them, and a constant length is formed at the lower end of the contact groove 41. An incision line 43 is formed. A connecting wire 110 of the fluorescent lamp 100 is attached to the contact groove 41. Then, the pair of guide plates 45 of each contact terminal 40 are formed to be inclined with respect to each other, and are pressed inside each other by a crimping plate 27 described later.

  The lid 20 attached to the upper part of the conductive base 30 is preferably molded from a synthetic resin. However, as shown in the figure, the lid 20 has a long plate-shaped upper plate 23 and a longitudinal direction of the upper plate 23. The first side plate 21 and the second side plate 22 are formed by bending the end portions of the both side surfaces downward.

  The first side plate 21 has a shape in which a plurality of cut openings 29 are formed. As shown in FIG. 5, the connecting wire 110 of the fluorescent lamp 100 passes through the cutout 29 and is attached to the contact groove 41 of the contact terminal 40. Therefore, the distance between the cut opening 29 and the adjacent cut opening 29 is the same as the distance between the contact terminals 40. The incision 29 may be formed to extend not only to the first side plate 21 but also to the upper plate 23 as shown in FIG.

  Further, as shown in the partial cutaway view of FIG. 2, a pressure plate 27 is formed on the lower surface of the upper plate 23 of the lid 20, and the cross section of the pressure plate 27 has a “U” shape, It is formed in a tapered shape. Therefore, the guide plates 45 of the contact terminals 40 are pressed inward by the crimping plate 27 so that the fluorescent lamp 100 connection line 110 is firmly attached to the contact groove 41 (see FIG. 4).

  As shown in the partially enlarged view of FIG. 2, a plurality of protrusions 28 are formed on the inner side surfaces of the first side plate 21 and the second side plate 22 of the lid 20 so as to be spaced apart from each other. The lid 20 is attached to the projecting groove 35 formed in 33 so that the lid 20 is coupled to the conductive base 30.

  The coupling between the fluorescent lamp according to the present invention and the integrated backlight fluorescent lamp fixing unit is as described below. 6 to 8 are diagrams illustrating an assembly process of the integrated backlight fluorescent lamp fixing unit according to the embodiment of the present invention. First, as shown in FIG. 6, the connection wires 110 of the fluorescent lamp 100 are respectively attached to the pair of contact terminals 40 exposed in the state where the lid 20 is opened (see FIGS. 5 and 7). After the connecting wire 110 of the fluorescent lamp 100 is mounted in the contact groove 41 of the contact terminal 40, the lid 20 is brought into close contact with the lower portion to be formed on the inner side surfaces of the first side plate 21 and the second side plate 22. The protrusions 28 are respectively attached to the protrusion grooves 35 formed on the side frame 33, the lid 20 is coupled to the conductive base 30, and the connection line 110 is attached to the gap formed in the cutout 29 (FIG. 8). reference).

  Then, the pair of guide plates 45 of the contact terminal 40 are pressed inside each other by the crimping plate 27, so that the connection line 110 attached to the contact groove 41 is more firmly coupled to the contact groove 41 (FIG. 4). reference).

  In another embodiment of the present invention, as shown in FIG. 9, rectangular rating plates 25 are further formed on both side surfaces of the crimping plate 27. The rating plate 25 can be molded integrally with the upper plate 23. When the lid 20 is coupled to the conductive base 30, the rating plate 25 is in close contact with the upper portions of the pair of side frames 33 and supports the lid. .

  The integrated backlight fluorescent lamp fixing unit 10 according to the present invention is used by being coupled to both ends of the fluorescent lamp as shown in FIG.

  As mentioned above, although embodiment of this invention was described in detail, this invention is not limited to this, As long as it has normal knowledge in the technical field to which this invention belongs, without leaving the thought and spirit of this invention.
