  • Publication number: 20040201950
    Abstract: The invention relates to a voltage transformer (1) including a housing (12) which encloses, at least partially, a mains plug (3, 4) connectable to a mains voltage source, a terminal plug (8) connectable to a terminal, and a voltage-transforming circuit, said housing (12) comprising a first housing component (2) and a second housing component (6) movably connected to said first housing component (2) by a guide means and implemented as a reception means (9) for receiving therein the terminal, and said voltage transformer (1) being adapted to be moved from a transport position to a charging position. In order to improve the handiness of the voltage transformer (1) during charging and, in particular, during transport, the present invention is so conceived that, at the transport position, the housing components (2, 6) have been moved relative to one another such that the space occupied at the transport position is smaller than that occupied at the charging position.

  • Patent number: 5540596
    Abstract: A device is described for supplying electrical current to electric appliances, especially mobile appliances. The device has a plug housing (1) equipped with an electric plug which houses the electrical and electronic components supplying the current. To simplify the use of the device with various electric socket configurations, several interchangeable adapter plugs (17) are provided which can be releasably attached to the plug housing (1). Each adapter plug has contact pins which are shaped and arranged according to electric socket configurations used in various countries. The adapter housing has contact springs (20) which are electrically coupled to the contact pins (19) and which contact corresponding current supply contact surfaces (8) carried by the plug housing (1). The plug housing (1) has a recess (2) into which a tongue (8) of an electronic circuit board (6) protrudes and on which the contact surfaces are formed.
