Description
Technical field
The present invention relates to a kind of plug-in power pack, this power supply has a shell and two circuit boards that are contained in this shell.The invention particularly relates to a kind of plug-in power pack that can be integrated in the plug, this plug for example is European plug.
Background technology
At present, the impetus that increases has appearred in the plug-in power pack device as the low power range of Switching Power Supply.Based on its small construction form and lighter weight, this power supply has obtained to use widely and replacing linear unit commonly used in the past
By constantly improving, be installed in the little shell with regard to succeeding in doing the plug-in power pack that is had about 3 watts power output many years ago.
In WO 03/094305 A1, provided the example of this plug-in power pack that is miniaturized.A wherein known example is that whole electronic building bricks and secondary end circuit element and primary side circuit element are contained on the continuous circuit board, and it is parallel to vertical side of shell.
From WO 03/094305 A1, can know a kind of embodiment of compactization of such plug-in power pack in addition, be about to whole functors and be installed in the European plug.At first this miniaturization plug-in power pack is and the development that is used for to the relevant worth pursuit of the traveling charger of mobile phone charging.Also propose in the document, shell is made of two and half shells, and it constitutes by inserting the overlapped rib of two and half shells according to desired air path of respective standard and leakage path.By ultrasonic wave two and half shells are welded together at last.
According to the document, the outline of header body does not exceed the size according to the European plug of standard.For circuit is installed, its proposition is contained in all electronic building bricks on the independent circuit board, this circuit board is parallel to the leptoprosopy setting of shell, and all primary sides and secondary end assembly all are installed on the same plane, only by known central dividing plate separately.
In principle, supply unit must satisfy the standard of the whole world about the secure context defined.Such as international standard IEC 60950 requirement about insulation between the assembly with different voltage levvls and minimum spacing has been proposed.IEC 61000 relates to the minimum requirement of Electromagnetic Compatibility.About the configuration of plug, what standard EN 50075 related to is so-called European plug.
