Abstract

(57) [Summary] In a structure in which a power transformer (5) is fixed to a boss body (6) (7) integrally formed on a synthetic resin cabinet (2), the boss body (6) (7) is connected. The convection movement passage (10) for air is formed by the reinforcing ribs (9), which are used for the cabinet (2) and the transformer (5).
Since the air between them is exchanged through the passage (10),
It is possible to prevent the temperature rise of the transformer (5) and stably maintain the function, and also to easily install the transformer (5) even in a small space.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a power transformer mounting device such as a television.

[0002]

[Prior Art]

 Conventionally, there has been a technique in which a boss is integrally formed on a synthetic resin cabinet and a power transformer is attached to the boss.

[0003]

[Problems to be solved by the device]

 In the prior art, since the reinforcing ribs are connected to the boss body to secure the power transformer support strength, the reinforcing ribs close the space between the transformer and the cabinet, and the power transformer is likely to rise above a predetermined temperature to deteriorate its function. There was a problem such as.

[0004]

[Means for Solving the Problems]

 However, the present invention is characterized in that, in the structure in which the power source transformer is fixed to the boss body integrally formed on the synthetic resin cabinet, the convection movement passage for air is formed by the reinforcing rib connecting the boss bodies. Since the air between the cabinet and the transformer is exchanged through the passage, the temperature rise of the transformer can be prevented and the function can be stably maintained, and the transformer can be easily installed even in a narrow space. It is a thing.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a front view of a main part, FIG. 2 is a front view of a television, FIG. 3 is a front view of a rear cabinet, and FIG. 4 is a side view. Box-shaped front and rear cabinets made of synthetic resin (1) (2) A cathode-ray tube (3) is internally fixed and fixed to the upper side of the above to form a television, and a video tape recorder (4) is provided to the lower side of the cabinets (1) and (2).

A power transformer (5) for converting a commercial power input into a desired AC power source is provided, and four boss bodies (6) for lateral support and four boss bodies for vertical support are provided. (7) are integrally formed on the inner surface of the rear vertical wall of the rear cabinet (2), and the four corners of the transformer (5) are formed by four screws (8). ) ... or (7) ... and the transformer (5) is mounted in the horizontal posture shown in FIG. 1 or the vertical posture shown in FIG.

Further, the bosses (6) ... (7) are connected by the reinforcing ribs (9) and (9), and the strength of the bosses (6) and (7) is increased by the ribs (9) and (9). At the same time, the ribs (9) (9) are separated into left and right to form a convection transfer passage (10) for air that communicates the upper side and the lower side. External cold air is taken into the cabinets (1) and (2) through the ventilation holes (11) on the side, and warm air inside the cabinets (1) and (2) is discharged from the ventilation holes (12) on the upper surface of the rear cabinet (2). At the same time, air is convectively moved from the lower opening of the passage (10) to the upper opening, and the air between the rear cabinet (2) and the transformer (5) is exchanged, and the temperature rise of the transformer (5) is prevented. Is configured as follows.

The transformer (5) is fixed in either the horizontal orientation of FIG. 1 or the vertical orientation of FIG. 6 depending on the specification structure, the wiring treatment, or the setting of the radiation magnetic force direction.

[0009]

[Effect of the device]

 As is apparent from the above-described embodiments, the present invention has a structure in which the power transformer (5) is fixed to the boss bodies (6) and (7) integrally formed in the synthetic resin cabinet (2) so that the boss body is fixed. (6) A passage (10) for convection movement of air is formed by a reinforcing rib (9) connecting the (7), and the air between the cabinet (2) and the transformer (5) passes through the passage (10). Since the transformers (5) are exchanged via the intermediary, the temperature rise of the transformer (5) can be prevented and the function can be stably maintained, and the transformer (5) can be easily incorporated even in a small space.
