The present invention relates to an integrated bracket provided with an exchange core for fixing a module, and more particularly, to a PDP module and a back cover which are simultaneously fixed to a circuit board, that is, a PDP of various manufacturers inside the bracket for coupling the circuit board to the back cover. The present invention relates to an integrated bracket equipped with an exchange core for fixing a module so as to minimize the change of the overall structure by replacing only the exchange core when a new PDP module is released by incorporating the exchange core compatible with the module.

As is well known, a plasma display panel (PDP) is generally referred to as 'PDP' for convenience, and is a display device that excites a phosphor by vacuum ultraviolet rays caused by gas discharge to implement a predetermined image. It is possible to configure, and it is attracting attention as next generation thin display device.

Such a plasma display device basically includes a PDP, a chassis base disposed substantially parallel to the PDP, a thermally conductive medium interposed between the PDP and the chassis base and closely attached to the PDP and the chassis base, and on the opposite side of the panel attachment surface of the chassis base. And a driving circuit mounted and connected to the PDP to drive the front panel. The front case is coupled to the PDP side, and the back case is coupled to the driving circuit side.

Here, the chassis base is usually die-cast or press-molded a metal such as aluminum having good rigidity and thermal conductivity so as to firmly mount the circuit board of the PDP while dissipating heat generated from the PDP and the circuit board to the outside. Used as

Plasma display device having such a configuration is used in the form of standing on the floor or fixed to the wall like a conventional television, in particular, in the case of a wall-mounted plasma display device, in order to install the device on the wall conventionally mounted on the chassis base Brackets having integrally molded plastic injection moldings used for fastening the wall-mounted bosses or integrated with the back cover were installed at four corners of the chassis base, respectively, and the display device was installed on the wall using the injection moldings.

An exploded perspective view schematically showing an example of such a conventional PDP module is shown in FIG. 1, and a cross-sectional view along the line II-II of FIG. 1 is shown in FIG. 2.

Referring to the drawings, a conventional PDP module includes a chassis base 30, a PDP 10 attached to the front surface of the chassis base 30, and a plurality of circuits fixed to the rear surface of the chassis base 30. And a circuit board 31 on which an element (not shown) is mounted.

The PDP 10 and the chassis base 30 are attached to each other by the adhesive force of the double-sided adhesive 20. The circuit board 31 is fixed to the chassis base 30 by fastening the fastening member 32 to the fixing boss 33 provided on the rear surface of the chassis base 30.

However, the conventional PDP module configured as described above has the following problems. The fixing boss 33 to which the circuit board 31 is fixed is manufactured separately by injection of aluminum (Al), and used by pressing the same into the chassis base 30. In the case of the conventional PDP device having such a structure, the wall-hung type In the case of the plasma display device, in order to install the device on a wall, a bracket 40 having a plastic injection molding used to integrally mold the wall-mounting boss to the chassis base 30 or to fasten the back cover is conventionally provided. The brackets 40 are installed at four corners of the chassis base, and the bracket 40 has a problem in that the circuit board 31, that is, the PDP module, must be changed to 1: 1 according to the structure of the module. Therefore, it was very disadvantageous economically.

Referring to Figures 2a, 2b, when explaining the bracket structure according to the PDP module of each PDP module manufacturers, the structure of the bracket is different according to the PDP module released by various PDP module manufacturers, Figures 2a, 2b also It is a bracket (40 '40 ") developed by a set company in response to a module of another PDP manufacturer.

The brackets 40 '40 "are all composed of a stand coupling portion 44 at a lower portion thereof, and are formed of a support plate in a long direction, and a plurality of component coupling holes and bosses 42 are formed on the upper surface thereof. The circuit board 31 is fixed to the chassis base 30 and has a structure for mounting a PDP on a wall for wall mounting, but the shape of the bracket 40 '40 "corresponds to a PDP module released by a PDP module manufacturer. It should be changed every time it is released, and all will differ depending on the product of each PDP module manufacturer. Therefore, as well as having a very short life cycle, as the PDP module is changed, the product has to be developed in a short period of time, there is a problem that it is very disadvantageous economically and time.
