BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a capsule-type transformer carried on a trip or the like.

[0002]

2. Description of the Related Art In general, the voltage of a commercial power supply and the form of a socket (socket) for taking out the voltage are not standardized in various countries as well as in the same country.

For this reason, when traveling abroad, it is necessary to always carry an adapter plug corresponding to the form of the commercial power supply socket at the destination and a transformer for transforming the voltage of the commercial power supply to an appropriate voltage for electric appliances. .

[0004] Usually, the adapter plug and the transformer have a pair of terminals (plugs) and an insertion port (socket) and are reduced in size and weight so as to be easily carried in a bag or the like.

[0005] When an electric appliance is used, an adapter plug and a transformer are sequentially connected to a commercial power supply, and then power is supplied to the electric appliance by inserting a terminal (plug) of the electric appliance into an insertion port of the transformer. .

[0006]

By the way, when a transformer is connected to the adapter plug, the insertion direction of the transformer may be in a vertical direction, and it is necessary to use the cordless type in a horizontal state. There is a problem that electric appliances such as a mosquito trap which cannot be used cannot be used.

Further, since the terminals (plugs) of the transformer are exposed to the outside, there is a problem that the bag itself and the contents of the bag are damaged when being carried or moved.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and has as its object to reliably use a cordless type electric appliance which must be used in a horizontal state. It is an object of the present invention to provide a transformer capable of preventing a peripheral member from being damaged by a terminal (plug) during carrying.

[0009]

In order to achieve the above object,
According to the present invention, a pair of insertion parts into which the plug of the electric appliance is inserted is rotatably mounted at one end of the transformer main body, and a pair of power supplies are connected to the other end of the transformer main body via an adapter plug. The terminal is characterized by being protruded.

[0010] Further, a locking means for locking the insertion portion at a desired angle is formed at one end of the transformer main body.

Further, a cap for covering the pair of terminals is detachably attached to the other end of the transformer main body.

Further, the pair of terminals are rotatably protruded from the other end of the transformer main body.

Therefore, according to the present invention, since the insertion portion or the pair of terminals are rotatably mounted on the transformer main body, even if the insertion direction of the transformer is vertical, the insertion portion or the pair of terminals can be used. By rotating the terminal at a desired angle (90 °), the arrangement direction of the insertion ports can be easily made horizontal.

At this time, since the locking means for locking the insertion portion at each desired angle is formed in the transformer main body, the insertion port is fixed at the desired angle position.

Since the cap for covering the pair of terminals is mounted on the transformer main body, the peripheral members are prevented from being damaged by the terminals when carrying.
