[Technical Field]

The present invention relates to a line filter assembly bracket of a microwave oven, and in particular, to assemble and fix the power cord as well as the assembly of the line filter, to assemble the power in a separate place such as a supplier and the assembly process in the assembly line and The present invention relates to a power cord mounting and line filter assembly bracket of a microwave oven which reduces assembly time.

[Background of invention]

In general, a microwave oven includes a line filter, which is an electronic circuit for adjusting a voltage and preventing external leakage of radio waves.

In the conventional microwave oven, as shown in FIG. 1, the line filter 1 is assembled to the bracket 2 inside the main body, and the power cord 3 connected to the line filter 1 is attached to the bracket 2. The mounting opening 4 which fixes the to is provided.

In addition, a cord insertion hole is formed in the rear panel 5 of the cabinet of the microwave oven, and a cord bushing 6 for preventing direct contact between the power cord 3 and the rear panel 5 is fitted in the cord insertion hole.

The power cord 3 enters into the cabinet through the cord bushing 6 in the assembly line and is fixed by the mounting hole 4, and the wire at the end thereof is connected to the line filter 1.

Thus, since the power cord 3 is fixed by the mounting opening 4 inside the cabinet, even if the power cord 3 is pulled from the outside, the tensile force does not reach the connection portion with the line filter.

However, the above-mentioned conventional microwave oven has a line filter assembly having a bracket (2) and a cord bushing (6) separately, and the power cord (3) is connected to the line filter (1) in the assembly line. . Therefore, it takes a lot of assembly time and accordingly there was a problem that the unit price of the product rises.

[Purpose of invention]

The present invention has been made in order to solve the above problems of the conventional microwave oven, the power cord of the microwave oven can be connected and fixed to the power cord more easily and the assembly work in the assembly line is simple and reduce the labor of assembly It is an object to provide a line filter assembly bracket.

[Summary of invention]

In order to achieve the above object, the line filter assembly bracket of the present invention has a vertical panel attachment portion in which a cord through hole is formed, and a horizontal filter assembly portion in which the line filter is assembled. It is characterized in that the plastic material for electrical insulation.

[Description of Specific Embodiment of the Invention]

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

2 is an assembled sectional view showing the line filter assembly bracket of the microwave oven of the present invention, and FIG. 3 is a plan view showing the assembly state of the line filter assembly bracket of the present invention.

The line filter assembly bracket of the microwave oven of the present invention is made of plastic material for electrical insulation, and is attached to the rear panel 5 of the cabinet as shown in the figure. The vertical panel attachment part 10 in which the 10a is formed, and the horizontal filter assembly part 11 to which the line filter 1 are assembled are integrated.

The power cord 3 is firmly fixed by tightening the mounting holes 13 with the screws 14 at the connection portions 12 of the panel attachment portion 10 and the filter assembly portion 11.

In order to fix the power cord 3 more firmly, the mounting holes 13 are formed with press-fit recesses and protrusions 13a on the upper and lower surfaces, and the reason why the press-fit recesses and protrusions 13a are formed on the upper and lower surfaces is as follows. The upper and lower surfaces of the upper and lower surfaces are symmetrical and can be assembled by directing either side toward the power cord 3.

The panel attachment portion 10 is formed with a spacer 15 extending rearward to maintain a predetermined space between the back of the microwave oven and the wall.

In the power cord mounting bracket of the present invention as described above, since the power cord 3 enters the cabinet through the cord through hole 10a, the power cord 13 and the rear panel 5 do not directly contact each other. There is no need for a separate code bushing 6 as in the prior art.

In addition, since the filter assembly 11 to which the line filter 1 is assembled is integrated with the panel mounting portion 10, when the panel mounting portion 10 is installed on the rear panel 5, the bracket 2 is mounted as in the prior art. There is no need to assemble inside the cabinet.

In addition, the line filter assembly bracket of the present invention is assembled in the assembly state by inserting the power cord (3) in the cord through hole (10a) and fixed by the mounting hole 13 before being put into the microwave assembly line, the pressure on the assembly line In the assembly line, the panel attachment part 10 needs only to be installed on the rear panel 5. Therefore, cumbersome work such as installation of the cord bushing, connection and fixing of the power cord, and installation of the line filter assembly bracket are required. There will be no.

As described above, the power cord mounting and line filter assembly bracket of the present invention can be connected and fixed to the power cord in a separate place such as a supplier and the assembly line, and the panel attachment part having the cord through hole 10a formed therein. (10) and the filter assembly 11, which is installed with the line filter is integrated, there is an advantage that the assembly work in the assembly line is simple and the assembly labor is reduced.

Claims (3)
