Description

Detailed Description of the Invention (Industrial Application Field) The present invention is applicable to foreign travelers who use Japanese-made electrical appliances, such as electric razors and radio power set coders, when the shape of the plug and the voltage differ from country to country. Therefore, since different standards are adopted, there is the inconvenience that these electrical appliances cannot be used directly in each country.To solve this inconvenience, we have developed a product that combines various types of plugs and transformers and can be used in many countries. This relates to a built-in plug device.

(Prior Art) Conventionally, many plug-in connection devices have been announced in which a plug blade of a specific shape is combined with a transformer. For example, Jikko 48-8
No. 7822, Utility Model Publication No. 49-88791, etc. However, most of these stores only one type of plug.

(Problems to be Solved by the Invention) The shape of the plug into which the outlet IC is inserted has different standards in each country, and there are many types, but typical examples are shown in Table 1. For example, ff1l shown in Table 1,
If you have a plug-in device that incorporates the four types of plugs described in 2.4.6 and a transformer, you can use it while traveling in a fairly wide area such as the UK, Europe, Asia, Australia, etc., or while staying in a certain place.
It is also very convenient when you suddenly go to another area.

However, in the past, there were only devices with one type of plug, and there were no devices that could be used in many countries, even if you were traveling to a specific country or staying for a long period of time, which was extremely inconvenient. Ta. Therefore, traveling to many countries,
When bringing and using Japanese-made electrical appliances, prepare separate plug adapters that comply with the standards for each region shown in Table 1 above, and use a plug set that includes several adapters. However, this has the drawbacks of dissipation and bulk, and in addition, since the 11CaE used is different, it was necessary to prepare a transformer. Therefore, the emergence of a device that compactly incorporates many types of plugs and transformers into one device has been awaited.

Japanese-made electrical appliances are designed to be used with a voltage of 100V, so of course they cannot be used in countries where commercial voltages of 220-240V are used, but many types of plugs can be used compactly. If combined with a transformer, it would be extremely convenient for overseas travelers.

(Note) As shown in Table 11, there are two types of plugs: round and square plate types, and in the present invention, these are used as a set at the same time, so the descriptive term hereafter will be unified as "bin plug".

(Means for Solving the Problems) In order to solve these problems, the present invention is based on various studies,
This was completed as a result of research and is explained with reference to the drawings. Box type I (configured plug device ac of the present invention @73)
If you press the knob αQ with your finger along the cross slint (!Q) provided on the top plate (9) of the cross slint (!Q) and move it in one of the four directions, the plug chamber will open. (3) The plug body 0ρ incorporated in the partition plate (2

Since it moves while sliding on the hill between the cross passages (5d) and 5d), when it is moved to the side wall of the desired passage, it is fitted and locked with the stopper at the stop position of the side wall.

At this time, the bottle plug protrudes to the outside from a hole formed in the side wall and has a shape corresponding to the shape of the plug, and is brought into contact with the outlet IC plug-in power source.

The plug insulating base (2) has four types (7) shown in Fig. 2 (A) (Bl ((:!l Cr)) +c).
P<) are provided protruding from each other, so the desired plug shape is protruded and used, but since this device has a built-in transformer (℃), the secondary side outlet contact piece of the transformer is used. ■Since mEE of 141007 is induced,
These appliances can be used easily and safely by simply inserting the cord of Japanese-made appliances or the plug attached to the appliance into the outlet window (2). .

Also, Fig. 2 (Δ) (B) (0) (11) tζ
As shown, when using any of the four types of pin plugs of this device, the terminal g4 (c)' (Fig. 4) attached to the plug insulating base (transfer) is connected to a pair of pin plugs. Since the terminal (a) on the partition plate (2) is connected to the terminal (a) on the hill, and the terminal (to) is connected to the primary coil of the transformer fTl, no operation is required during this time. It is structured so that there is.

Thus, the converted voltage can always be taken out from the contact piece (7) of the plug-in socket as a power supply. The contact piece is of Japanese standard, and can be plugged with a plug for electrical diagnostic equipment made in Japan or the United States with a voltage of 10 l.The plugs shown in Figure 2 are appropriately selected from Table 1. You can freely combine them.

(Function) Since the plug device of the present invention is equipped with four types of bottle plugs based on foreign standards, the plug device can be used in many foreign countries in compliance with the standards of those countries, and the plug device can be used in many foreign countries. From the transformer lζ, the high voltage in Table 1 is 10
0V and the outlet on the secondary wiring side was shaped according to Japanese standards, so Japanese-made electrical appliances were the first choice.
It can be used freely in the foreign countries shown in the table.
