Description
The present invention relates to a lamp socket, a backlight unit having the same, and a method of manufacturing a backlight unit, and more particularly, to a lamp socket having a reduced number of parts and a simplified work process, and a backlight unit having the same and a method of manufacturing a backlight unit. .
The liquid crystal display device displays a desired image on the liquid crystal display panel by adjusting the amount of light transmitted according to the image signals applied to the plurality of control switches arranged in a matrix form. Since the LCD does not emit light by itself, a light source such as a backlight is required. Generally, a lamp unit including a lamp and an inverter for supplying power to the lamp is used as the light source.
Most of the methods used for fixing lamps are holding types. These holding types are soldered wires to the lamp leads and then bonded to the housing using a silicone-based elastic material. It is a method of coupling to an inverter. However, this method requires manual soldering of the lamp leads and wires by hand, and all operations such as fastening to the holder and fastening of the connector are performed by hand, which leads to various problems such as assembly and productivity of each part and the number of parts. Have
On the other hand, in the case of the socket type (Socket Type) improved by this, the socket is used as a component for fixing the lamp. This improves the assembly and workability compared to the conventional soldering and holding type using wires, but a large number of parts are used per socket for fixing the lamp, which increases the number of work processes and the cost. There is this.
SUMMARY OF THE INVENTION The present invention has been made in an effort to provide a lamp socket, a backlight unit having the same, and a method of manufacturing a backlight unit having a reduced number of parts and a simplified work process.
According to an embodiment of the present invention, a contact terminal electrically connected to a lamp and fixing the lamp; And a housing coupled to the contact terminal, wherein the contact terminal comprises: a contact body part; A first contact portion formed to extend from the contact body portion and to which the lamp is disposed and fixed; And a first fastening part formed on one surface of the contact body part, wherein the housing comprises: a housing body part accommodating the contact terminal; A guide part formed in the housing body part to guide the position of the first contact part; And a second fastening part formed on the housing body part and fastened to the first fastening part of the contact terminal.
The contact terminal further includes a second contact portion coupled to the inverter and electrically connected to the inverter, and the housing further includes an opening formed in the housing body portion to expose a portion of the second contact portion.
The contact terminal further includes a pressing portion formed at one end of the contact body portion.
The pressing portion extends in a direction different from an extending direction of the contact body portion.
The first contact portion has a head formed of a structure having elasticity, and a fixed strength of a lamp disposed and fixed to the head is variable.
The heads are spaced apart from each other and consist of first and second heads arranged oppositely.
The first head and the second head are formed to be interconnected.
The first fastening portion and the second fastening portion include a fastening protrusion or a fastening hole.
The second contact portion is formed in a structure having elasticity.
According to another embodiment of the present invention, a lamp having a lamp tube and lamp leads provided at both ends of the lamp tube; And a lamp socket configured to apply power to the lamp and to fix the lamp, wherein the lamp socket is electrically connected to the lamp and fixes the lamp. And a housing coupled to the contact terminal, wherein the contact terminal comprises: a contact body part; A first contact portion formed to extend from the contact body portion and to which the lamp lead is disposed and fixed; And a first fastening part formed on one surface of the contact body part, wherein the housing comprises: a housing body part accommodating the contact terminal; A guide part formed in the housing body part to guide the position of the first contact part; And a second fastening part formed on the housing body part and fastened to the first fastening part of the contact terminal.
The backlight unit further includes an inverter for supplying power to the lamp, the contact terminal further includes a second contact portion coupled to the inverter and electrically connected to the housing, and the housing includes a portion of the second contact portion. In order to expose, further comprises an opening formed in the housing body portion.
According to another embodiment of the present invention, a contact including a contact body portion, a first contact portion formed extending from the contact body portion, the lamp is disposed and fixed and a first fastening portion formed on one surface of the contact body portion Terminals; And a housing body part accommodating the contact terminal, a guide part formed in the housing body part to guide the position of the first contact part, and formed in the housing body part, the first fastening part of the contact terminal. Preparing a lamp socket having a housing including a second fastening portion to be fastened; Placing a lamp in a first contact portion of the lamp socket; And fixing the lamp to the first contact part.
The fixing of the lamp to the first contact unit may include pressing the contact terminal; And fastening a first fastening part of the contact terminal and a second fastening part of the housing.
Pressing the contact terminal includes disposing the first contact portion in the housing body portion via the guide portion.
The number of parts is reduced, the work process is simplified, the defect rate can be significantly reduced, and the overall manufacturing cost can be reduced.
In addition, it is possible to improve the fastening force between the lamp and the lamp socket, thereby obtaining the effect of improving the product reliability.
