Description

[Detailed Description of the Invention] This invention relates to a transformer device, and is characterized by its mounting structure.

In electronic devices such as audio equipment such as cassette decks,
The transformer is relatively heavy compared to other built-in parts.
In particular, improvement of the mounting structure is desired.

If a mounting piece is provided on the outer casing of the transformer and this is directly attached to a printed circuit board, etc. using screws, etc., the screw tightening part may become loose, or the board hole through which the screw passes may be damaged. There are things to do.

This is due to the fact that the thickness of the circuit board and other components has been reduced in order to downsize the electronic device as a whole and conserve resources in each component.As a result, the transformer is relatively heavy, and the mounting part (especially the screw tightening part) is large. This is due to the fact that stress is more easily applied.

This idea was made to deal with the above circumstances,
It is an object of the present invention to provide a transformer device having a simple configuration and a stable and strong mounting state of the transformer.

Examples of this invention will be described below with reference to the drawings.

FIG. 1 shows a cassette deck 11 to which this invention is applied, and its size is reduced.

A transformer device 12 is provided on the rear plate 111 of the cassette deck 11.

The mounting structure of the transformer device 12 is, for example, as shown in FIG.

That is, 13 is a transformer main body, and wing pieces 14 and 15, which are partially bent outer casings, are formed on the left and right sides of the bottom surface of the transformer main body, and are set substantially parallel to the bottom surface.

The wing pieces 14 and 15 have holes 14 and 15 for screws to pass through.
．． is formed.

On the other hand, 16 is a comb-shaped metal plate, which has approximately the same area as the bottom surface of the transformer main body 13 and has a first flat portion 17 that is in close contact with the bottom surface, and a nut portion 18 that corresponds to the wing pieces 14 and 15. It has a second planar portion 18.19 forming 19□.

This comb-shaped metal plate 16 slides parallel to the bottom surface of the transformer body 13 (moves as indicated by the arrow in the figure), so that the first flat portion 17 is brought into close contact with the bottom surface of the transformer body 3, and the second flat portion 18. 19 are attached to the upper surfaces of the wing pieces 14 and 15 so as to be heavy.

This is possible because the comb-shaped metal plate 16 has notches 16a and 16b, as shown in FIG.

When the transformer body 13 and the comb-shaped metal plate 16 are integrated, they are placed on the mounting plate 20, as shown in FIG.

The nut portions 18□, 19 are attached to the mounting plate 20.
A hole is formed corresponding to □.

Then, the screws 21 and 22 are used to tighten the nut portions 18□ and 1.
By being tightened to 91, the transformer body 13 is fixed.

According to this invented device described above, the comb-shaped metal plate 16 is
It has a flat plate shape and can be manufactured at low cost.

Further, as can be seen from the attached state shown in FIG. 4, the core portion of the transformer body comes into contact with the mounting plate 20 via the metal plate 16, so that heat is not trapped here and the heat dissipation effect is improved.

Further, since the comb-shaped metal plate 16 is comb-shaped, it can be temporarily fixed to the transformer body, thereby improving workability.

Furthermore, since the comb-shaped metal plate 16 is used, the attached plate 2
The contact surface between the transformer and the transformer becomes larger, and the weight of the transformer is not applied locally to vibrations, but is dispersed.

For this reason, compared to a structure that is simply attached with screws,
Damage to the screw insertion holes on the mounting plate is greatly reduced.

In addition, the positional relationship between the comb-shaped metal plate 16, the transformer body, the blades, etc. is such that they are engaged with each other by a moderate elastic force, so the mounting state is stable and the tightening effect of the screws on the mounting plate 20 is improved. Effectively demonstrated.

As described above, this invention can provide a transformer device that has a simple structure, improves workability, and provides installation stability.
