Problems solved by technology

[0005] However, the AC adapter is configured such that the first circuit board assembly is installed on the right side in the case, the second circuit board assembly is installed on the left side in the case, and the insulating member is installed in the center of the case to separate the second circuit board assembly. Between the first circuit board assembly and the second circuit board assembly, it is necessary to fix the first circuit board assembly, the second circuit board assembly, and the insulating parts in the housing respectively, so the assembly of the AC adapter is poor
[0006] In addition, since it is a structure in which the first circuit board assembly, the second circuit board assembly, and the insulating member are all fixed in the case, considering assembly work, etc., between the first circuit board assembly and the insulating member and between the second circuit board There are some gaps between the components and insulating parts, and the AC adapter cannot be said to be small enough

Abstract

A switching regulator circuit assembly housed in a case is disclosed. The assembly includes a first and a second circuit board assemblies each having a circuit board on which electronic parts are mounted and an insulator member having an electronic parts enclosing part for enclosing the electronic parts. The first and second electronic board assemblies are fixed to each other with the insulator member disposed in between; accordingly the electronic parts are enclosed in the electronic parts enclosing part.

Description

technical field [0001] The present invention relates to an AC adapter (AC adapter), and relates to a small AC adapter used for charging a portable device or the like. Background technique [0002] A conventional AC adapter has a structure in which a switching regulator circuit unit is housed in a case made of synthetic resin. The AC adapter is required to be miniaturized. [0003] An example of an AC adapter that achieves miniaturization has a structure in which a switching regulator circuit assembly is divided into two, a first circuit board assembly and a second circuit board assembly, the two are connected with a cable, and the first circuit board assembly Put it into the casing, put the second circuit board assembly into the casing, the electronic components of the first circuit board assembly and the electronic components of the second circuit board assembly have a relative positional relationship, and put the plate-shaped insulating part into the casing and separated...
