Description

Holder structure for fixing printed circuit board of TV

The present invention relates to a holder coupling structure for fixing a printed circuit board of a television, and more particularly, to simplify and easily combine a structure of a holder for fixing a printed circuit board installed in a front cabinet of a television.

In general, a television is a device for reproducing image and audio information transmitted by an imaging device and a microphone to an original image and sound using a receiver tube and a speaker of a receiver, and transmitting the image and audio information to a viewer. Is converted into an electrical signal and received by an antenna connected to the television, and the electrical signal received through the antenna is reproduced as an image and sound through a water pipe and a speaker.

In a conventional television, as shown in Fig. 1, a guide rail 3a for inserting a printed circuit board 2 into a front cabinet 1a is formed, and a seating hole 8 formed at one side of the guide rail 3a. The holder 5a having a fixing groove 9 for fixing the printed circuit board 2 inserted into the guide rail 3a is inserted into the holder 5a to fix the printed circuit board 2. do.

However, such a conventional holder (5a) is pressed during packaging to cause breakage and deformation, and the failure of locking does not occur due to the occurrence of burrs of the front cabinet (1a), etc., the holder (5a) There are many problems, such as the hinge portion of the deformation of the injection and assembly is not able to properly perform the role of a stopper of the printed circuit board (2).

The present invention is to solve the above problems, it is possible to simplify the structure of the holder for fixing the printed circuit board installed in the front cabinet of the TV can be easily combined as well as to reduce the size of the holder to manufacture the parts It is an object of the present invention to provide a holder coupling structure for fixing a printed circuit board of a TV, which can reduce cost and prevent damage caused by the holder being pressed during packaging.

In order to achieve the above object, the present invention is a holder coupling structure for fixing a printed circuit board of a television which is configured to couple a holder for fixing a printed circuit board installed in a front cabinet of a television, which is formed in the front cabinet and printed A fixing hole is formed at one side of the guide rail into which the circuit board is inserted, and a lower end of the holder for fixing the printed circuit board is inserted into the fixing hole, and an unevenness for fixing the holder to be in close contact with the wall of the guide rail. This is achieved by providing a holder coupling structure for fixing the printed circuit board of the formed television.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention in detail as follows.

2 is an exploded perspective view illustrating a state in which a holder for fixing a printed circuit board is coupled to a front cabinet according to the present invention, and FIG. 3 is a longitudinal cross-sectional view of the coupled state of FIG. And a fixing hole 4 formed at one side of the guide rail 3 into which the printed circuit board 2 is inserted, and a holder 5 for fixing the printed circuit board 2 to the fixing hole 4. The lower end portion of the holder 5 is inserted, and the inner surface of the holder 5 is formed with an unevenness 6 for fixing the holder 5 to be in close contact with the wall of the guide rail (3).

In addition, a reinforcing rib 7 for preventing the holder 5 from flowing is formed integrally under the fixing hole 4 of the front cabinet 1.

2 and 3, the present invention configured as described above is inserted into the guide rail 3 while the printed circuit board 2 is inserted into the guide rail 3 formed in the front cabinet 1 of the television. When assembling the holder 5 for fixing the printed circuit board 2, the lower end of the holder 5 is fixed to the fixing hole 4 formed at one side of the guide rail 3 of the front cabinet 1 from the top to the bottom. As the upper portion of the holder 5 is forcibly inserted into the guide rail 3 while being inserted into the guide rail 3, the unevenness 6 formed on the inner surface of the holder 5 closely adheres to the wall of the guide rail 3 so that the holder 5 can be easily moved. Can be assembled.

On the other hand, since the reinforcing ribs 7 are integrally formed under the fixing hole 4 of the front cabinet 1, the holder 5 inserted into the fixing hole 4 at the lower end thereof can be prevented from flowing.

As described above, the present invention simplifies the structure of the holder for fixing the printed circuit board installed in the front cabinet of the TV, can be combined in an easy and solid state, and the size of the holder can be reduced to 1/2, so that It is possible to reduce the manufacturing cost, prevent damage due to the pressing of the holder during packaging, and it is a very useful design with many advantages such as easy assembly and disassembly of the holder even if the precision of the dimension is not high.

The present invention is not limited to the above-described specific preferred embodiment, and any person having ordinary skill in the art to which the present invention pertains may make various modifications without departing from the gist of the present invention claimed in the claims. Of course, such changes will fall within the scope of the claims.
