Abstract

A case of a power supply is provided to improve cooling efficiency by transmitting the heat of a circuit body to a case body through a fixture. A case of a power supply includes a case body(10), a fixture(20), a cover(30), a coupling unit, and a sealing pad(40). Four surfaces of the case body are closed. An opening(11) is formed in both sides of the case body. A bottom surface, a front surface, and a rear surface of the fixture are closed. The upper surface and both sides of the fixture are opened. The fixture is inputted or outputted to the opening of the case body. A cover covers both sides of the case body. The coupling unit is formed in the case body and the fixture. The coupling unit is inserted into a slide groove(12) of a case body. The sealing pad is overlapped in the inner side of the cover.

Description

Case for power supply

The present invention relates to a case of a power supply for supplying power to a display board or an advertisement device, and more particularly, it is possible to easily assemble a circuit device therein, to effectively dissipate heat generated from the circuit device, and to be waterproof in rainy weather. It relates to a case of a power supply.

The case of a conventional power supply is composed of a bottom plate 1 and a cover 2, as shown in Figure 1, the bottom plate 1 is formed with a slide groove (1a) and the cover (2) the insertion portion (2a) is formed by bending the bottom plate (1) and the cover (2) is configured to separate the rainwater and the like between the slide groove (1a) and the inserting portion (2a) made to join them If it is difficult to prevent and deformation occurs due to an external shock, a gap between the slide groove 1a or the inserting portion 2a is opened, which adversely affects the safety of the internal circuit device.

The present invention has been made to solve the problems of the prior art as described above, it is an object of the present invention to provide a case of a power supply that is easy to install the circuit board, waterproof in the rain and excellent heat dissipation effect.

The present invention for achieving the above object, the upper and lower front and rear surfaces are closed and both sides of the opening to the opening;

A circuit board fixture having bottom and front and rear surfaces closed, top and side surfaces open, and accessible through an opening of the case body;

A cover covering both side surfaces of the case body;

In addition, there is another feature is formed in the case body and the coupling means for coupling to the circuit board fixture,

In addition, the present invention has another feature by overlapping the sealing pad on the inner surface of the cover.

In the present invention having the above characteristics, the case body is not dualized and is formed in a cylindrical body, so that there is no fear of being submerged even if it is deformed by an external impact, and the circuit board is installed in a fixture so that the installation of the circuit board is robust. Heat generated from the board is transferred to the case body through the circuit board fixture and radiates to the outside of the case, so the cooling effect is excellent, and by maintaining the space between the circuit board and the fixture, external energy is transmitted to the circuit board. Therefore, it is possible to prevent the occurrence of condensation on the circuit board.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

Figure 2 is an exploded perspective view showing a preferred embodiment of the present invention, Figure 3 is a cross-sectional view of the present invention, Figure 4 is a cross-sectional view of the cover portion of the present invention.

As shown, the present invention includes a fixture 20 on which the case main body 10 and the circuit board 50 are installed, and a cover 30 covering both openings of the case main body 10.

The case body 10 has a square pipe shape in which four sides are closed, i.e., four sides are closed, and openings 11 are formed at both sides. In addition, a coupling means, that is, an upper slide groove 12 and a lower slide groove 13, in which the fastener 20 is slidably mounted at four corners, is formed therein. These slide grooves 12 and 13 are used for mounting the fixture 20, but also serve as fastening holes for fastening the screws 35 for fastening the cover 30. In addition, the uneven surface 14 is formed on the surface to increase the heat radiation effect.

The fixture 20 has a bottom surface 21 and front and rear surfaces 22 are formed, and the top and both sides are open. In addition, the outer lower portion of the front and rear surfaces 22 is formed with a coupling means that is inserted into the slide groove 12, that is, the protrusion piece 23.

The slide grooves 12 and 13, which are the coupling means of the case body 10, or the protrusion pieces 23, which are the coupling means of the fixture 20, are for easily mounting the fixture 20 in the case body. If it can be used in various forms and formed for the same purpose as the present invention will belong to the scope of the technical idea of the present invention.

The cover 30 covers the opening 11 of the case body 10, and edges 31 surrounding the case body 10 are formed at corners and upper sides of the case body 10, and fixing pieces 32 are formed at the front and rear and bottom thereof. ) Is bent and these fixing pieces 32 are provided with fastening grooves 32a and fastening holes 32b so as to be fixed by screws or bolts. In the center of the cover 30, a through hole 33 is drilled to penetrate the wire cable 51 connected to the circuit device 52, and a rubber ring 33a is fitted in the through hole 33.

In addition, the sealing pad 40 is overlapped on the inner surface of the cover 30, the sealing pad 40 is preferably made of a material such as rubber or synthetic resin excellent in the sealing function.

As described above, the present invention can stably supply electricity to an electric signboard or an advertisement board, and the case body and the fixture are formed by extending and extruding aluminum by a predetermined length, and the cover is produced by pressing.

So there is no problem with industrial use.
