Abstract: A plug-in power supply wherein the mains plug unit is exchangeable in the form of a conversion plug system. The plug-in power supply includes a housing having a voltage transformer module for converting a mains voltage into the required low voltage, and an exchangeable mains plug unit with at least two mains plug pins. The plug-in power supply includes an exchangeable mains plug unit, and the housing includes at least two spring contacts which are electrically connected to the voltage transformer module. The mains plug unit includes at least two contact pins which cooperate with the spring contacts so as to establish an electric contact with the mains plug pins, and each contact pin is arranged in a separate recess.

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.
