Field of the Invention The present invention relates to a liquid crystal display device, and more particularly, to a copper structure for connecting lamp wires of a lamp device for a liquid crystal display device. [0002] Generally, a liquid crystal display device includes a plurality of liquid crystals arranged in a matrix form. The liquid crystal panel is composed of cells and a plurality of control switches for switching a video signal to be supplied to each of these liquid crystal cells, thereby controlling a transmission amount of light supplied from a back light unit to display a desired image. Will be displayed.

1 is a structural sectional view showing a lamp device according to the prior art.

As shown in FIG. 1, a lamp device for a liquid crystal display device includes a lamp 2 generating light and a lamp lead wire connected to one end of the lamp 2 to supply an external power source (not shown). (Lamp lead wire: 2a), a wire electrically connected to the lamp lead wire (2a) for supplying external power to the lamp (Wire: 3) and wire core wire (3a), and the lamp (2) and the wire Solder 4 for electrically contacting (3), a tube (10) surrounding the lamp lead wire (2a) and the wire (3), and formed while wrapping a portion of the lamp and the tube (10) The lamp 2 is configured to generate light by receiving an external power supply through a wire 3 connected to the lamp lead wire 2a. As described above, the wire 3 is connected to the lamp lead wire 2a for supplying external power to the lamp 2 by the solder 4 using lead.

2A to 2E are cross-sectional views illustrating a process of connecting a lamp and a wire according to the prior art.

First, as shown in FIGS. 2A and 2B to electrically connect the lamp 2 and the wire 3, the ends of the lamp lead wire 2a and the wire 3 are cut and covered to a standard. Peel off.

Then, when the ends of the lamp lead wire (2a) and the wire (3) is cut in accordance with the standard, as shown in Figure 2c, the solder (4) to electrically connect the wire and the lamp lead wire (2a) Done. This solder 4 is made by twisting the wire core wire 3a to the lamp lead wire 2a, as shown in FIG. 2D. The lamp lead wire 2a and the wire 3 are electrically connected by the solder 4 so that external power is supplied to the lamp 2. When the lamp 2 and the wire 3 are electrically connected by the solder 4, the lamp 2 and the solder 4 are wrapped around the lamp 2 and the solder 4 using the tube 10 as shown in FIG. The work is performed to ensure the reliability of the breakdown voltage and the disconnection of the solder 4 and the outer portion of the wire 3. Such a wrapping operation using the tube 10 is performed by hand.

Finally, in order to integrate the lamp 2, the solder 4 portion and the wire 3, rubber is applied as shown in FIG. 1 to integrate it. In more detail, the lamp holder 5 including the part covered by the tube 10 shown in FIG. 2E and a soft rubber material is finally applied to the inner portion of the end of the lamp 2.

By proceeding the above process, the lamp 2 and the wire 3 are electrically connected and are integrated by the tube 10 and the lamp holder 5.

However, the lamp device according to the conventional solder connection structure has the following problems.

First, in the conventional lamp solder structure, the length of the lamp lead wire is a key factor of the defective rate, and the design limit (Spec) of such lamp lead wire is from 1.6 mm to 1.2 mm. Therefore, when the cutting of the lamp lead wire is made shorter than the above design limit and the solder is made, the soldered portion is shortened, and thus, the soldered portion is not made, so that the soldered portion falls. This will occur.

Second, in the conventional lamp solder structure, despite the above-described problems, once the solder is made, it is impossible to determine it through vision, and thus there is no method for detecting such lamp lead wire cutting defects except the inspection method through x-ray transmission.

Third, in the conventional lamp solder structure, soldering was conducted by twisting the core wire of the wire to the lamp lead wire during soldering for the electrical connection between the wire and the lamp lead wire. .

The present invention has been made to solve such a problem, it is possible to make a more solid coupling when soldering the lamp lead wire and the wire, and at the same time need to detect the defects due to the lamp lead wire cutting in advance and solder the core wire twisted It is an object of the present invention to provide a lamp device for a liquid crystal display device without.

According to an aspect of the present invention, there is provided a lamp device for a liquid crystal display device including a lamp including a lamp lead wire for applying power, a wire for supplying external power to the lamp, and an end extending from a flat bottom surface. And a first curved line and a second curved part which are rolled up so that each outer peripheral surface is in contact with each other, and a space where the core wire of the wire is to be inserted at the central portion between the contact portion and the bottom of each of the outer peripheral surfaces of the first and second curved parts A connecting ring comprising a first insertion portion formed therein, a plate-shaped plate portion and a second insertion portion in which a hole into which the lamp lead wire is inserted is formed, and the core wire of the wire and the lamp lead wire cross each other. And electrically connecting the lamp and the wire at an intersection of the core wire of the wire and the lamp lead wire. The core wire of the wire inserted into the space is in contact with each of the outer circumferential surfaces of the first and second curved portions and the bottom surface, and the first insertion portion, the plate portion, and the first portion constituting the connecting ring. The insertion part is integrally formed.
