PARTIALLY COMPOUND-FILLED POWER SUPPLY UNIT AND MANUFACTURING METHOD
First Claim
1. A power supply unit for supplying a consumer with a low voltage, comprising:
- at least one power plug contact (106, 206) connectable to a supply voltage;
at least one output lead (114, 214) for outputting the low voltage;
a voltage transformer unit comprising at least one electronic component for transforming the supply voltage to the low voltage;
wherein the power supply unit (100, 200) comprises a casing made of a casing base element (102, 202) and a lid element (102, 202), and wherein the at least one power plug contact (106, 206) is held in the casing base element (102) or in the lid element (204) in such a way that it can be plugged into a power socket, wherein the voltage transformer unit is mounted on a circuit carrier (108, 208), which is arranged in the casing base element (102, 202), in a plug-in direction (126) of the power plug contact (106), in such a way that a defined first region (128) of the circuit carrier (108, 208), which is to be insulated, is received in a casting space (118, 218) that is enclosed by walls of the casing base element (102, 202),and wherein the casting space (118, 218) of the casing base element (102) is filled with an electrically insulating casting compound, so that the first region (128) of the circuit carrier (108), which is to be insulated, is covered by the casting compound, while a second region (130) of the circuit carrier, on which the at least one electronic component is arranged, is not encapsulated.

Abstract
A power supply unit is provided for supplying low voltage power. The supply unit includes at least one power plug contact connectable to a supply voltage; at least one output lead for outputting the low voltage; and a voltage transformer unit having at least one electronic component for transforming the supply voltage to the low voltage. The power supply unit includes a casing made of a casing base element and a lid element, such that the power plug contact is held in the casing base element or in the lid element in such a way that it can be plugged into a power socket. The voltage transformer unit is mounted on a circuit carrier which is arranged in the casing base element in such a way that a defined first region of the circuit carrier is received in a casting space filled with an electrically insulating casting compound.
