Two insertion pieces 22 are provided on the front surface of the plug main body 21, and a base portion 21 </ b> A that engages with the opening 13 of the case 11 is provided as a fitting portion on the side surface. Stand on both sides of the portion 21A step 21A 1 are mounted on the front of the base portion 21A, 2 two contact pieces 23 are provided. In the plug main body 21, the insertion pieces 22 are electrically connected to the contact pieces 23, respectively. The insertion piece 22 is inserted into an outlet (not shown) and an AC voltage is applied.

前記構成の電源アダプタでは、台部分21Aは、電源部1の開口13に嵌め合う。つまり、開口13の両側が台部分21Aの段差21Aに嵌め合うように、プラグ部2は開口13に取り付けられる。これにより、プラグ部2が電源部1に固定される。プラグ部2の固定と同時に、図4に示すように、プラグ部2の接触片23が電源部1の基板12の受け部分14に差し込まれて、差し込み片22が受け部分14と電気的に接続される。これにより、プラグ部2からの交流電圧が電源部1に供給される。なお、本実施形態では、接触片23と受け部分14とにより接合部が構成されている。 In the power adapter configured as described above, the base portion 21 </ b> A fits into the opening 13 of the power supply unit 1. That is, as both sides of the opening 13 mate with the step 21A 1 of the base portion 21A, the plug unit 2 is attached to the opening 13. Thereby, the plug part 2 is fixed to the power supply part 1. Simultaneously with the fixing of the plug part 2, as shown in FIG. Is done. Thereby, the AC voltage from the plug unit 2 is supplied to the power source unit 1. In the present embodiment, the contact piece 23 and the receiving portion 14 constitute a joint portion.

本実施形態では、図5(a)、(b)に示すように、各電源事情に対応した電源ピン31A、32Aを備えるプラグ部31、32や、図5(c)に示すように、電源ケーブルが差し込まれるインレットを、プラグ部2とは別に用意すれば、本実施形態による電源アダプタは、異なる電源事情にも対応可能である。しかも、本実施形態では、プラグ部2を電源部1に差し込むだけで、電源部1とプラグ部2とを電気的に接続した状態になるので、接続を簡単に行うことができる。   In this embodiment, as shown in FIGS. 5 (a) and 5 (b), as shown in FIG. 5 (c), as shown in FIG. 5 (c), as shown in FIGS. If the inlet into which the cable is inserted is prepared separately from the plug portion 2, the power adapter according to the present embodiment can cope with different power supply situations. In addition, in the present embodiment, the power supply unit 1 and the plug unit 2 are electrically connected only by inserting the plug unit 2 into the power supply unit 1, so that the connection can be easily performed.

以上、本発明の実施形態を詳述してきたが、具体的な構成は本実施形態に限られるものではなく、本発明の要旨を逸脱しない範囲の設計の変更等があっても、本発明に含まれる。たとえば、電源部1とプラグ部2とを接続するために、図6(a)に示すように、プラグ部2の台部分21Aには、差し込み片22と電気的に接続された端子41を設け、基板12には、受け部分14の代わりにホール12Aを設ける。そして、端子41とホール12Aとを多心のケーブル42で接続してもよい。   Although the embodiment of the present invention has been described in detail above, the specific configuration is not limited to this embodiment, and even if there is a design change or the like without departing from the gist of the present invention, the present invention is not limited thereto. included. For example, in order to connect the power supply unit 1 and the plug unit 2, as shown in FIG. 6A, the base portion 21 </ b> A of the plug unit 2 is provided with a terminal 41 electrically connected to the insertion piece 22.
