Abstract

PURPOSE:To improve the flexibility for installation conditions by connecting desired common connectors together and forming a feeder path from an AC plug to a DC plug. CONSTITUTION:Since common connectors 50 can be connected together between male types and between female types, an AC/DC common cable 20 can be connected to the AC input section and the DC output section of an AC/DC adapter main body 30. A cable with AC plug 10 and a cable with DC plug 40 can be connected to the AC input section and the DC output section of the AC/DC adapter main body 30 respectively. The AC/DC adapter main body 30 can be optionally rearranged on the DC plug 42 side or the AC plug 12 side respectively in response to the conditions whether the AC/DC common cable 20 is connected to the AC input section or to the DC output section. The flexibility for the arrangement conditions can be thereby improved.
