常に小型で簡便な電源ジャックを提供することを目的と
するものである。[Detailed description of the invention] The invention relates to a power jack equipped with a secondary side changeover switch, and the insulation distance between the negative side connection terminal and the secondary side terminal and the insulation distance between the negative side connection terminals. The purpose is to provide a very small and simple power jack that prevents the risk of electric shock by ensuring sufficient capacity, and prevents external force from being applied to the soldering part of the - side lead wire. It is.
一般に二次側切換スイッチを備えた電源ジャックにおい
て電源ジャックの小型化を考える場合、−次側接続端子
と二次側接続端子間の絶縁距離不足が問題となることが
多い。Generally, when considering miniaturization of a power jack equipped with a secondary side changeover switch, insufficient insulation distance between the negative side connection terminal and the secondary side connection terminal often becomes a problem.
そのため、−次側端子部と二次側端子部間の絶縁距離を
確保する為に、二次側突出し部を長くしたり、−次側端
子と二次側端子を別々の側面に突出して設ける等しなけ
ればならず形状が大きくなるという欠点があった。Therefore, in order to ensure the insulation distance between the negative side terminal part and the secondary side terminal part, the secondary side protruding part is made long or the negative side terminal and the secondary side terminal are provided so as to protrude from different sides. There was a drawback that the shape had to be equal and the shape became large.
また、−次側半田付は部から出た二次側リード線は輸送
中の振動、その他の振動により動くものであり、さらに
二次側部品が外れた場合には一次側半田付は部に触れる
ことにより、感電の危険が生じる等の欠点があった。In addition, the secondary lead wire coming out of the negative side soldering section moves due to vibrations during transportation or other vibrations, and if the secondary side component comes off, the primary side soldering There were drawbacks such as the risk of electric shock if touched.
本考案は以上のような従来の欠点を除去するものであり
、作業性よく確実に絶縁距離を確保すると共に、−次リ
ード線の固定についでも十分な強度をもった極めて小型
の電源ジャックを提供するものである。The present invention eliminates the above-mentioned drawbacks of the conventional jack, and provides an extremely compact power jack that is easy to work with, secures a reliable insulation distance, and is strong enough to secure the negative lead wire. It is something to do.
以下、本考案の一実施例について図面とともに説明する
。An embodiment of the present invention will be described below with reference to the drawings.

欠き２５とボス３，４に取り付けている。It is attached to the case using screws 22 and 23 in the attachment hole 24 of the protective cover 18, the attachment notch 25 of the power jack body 2, and the bosses 3 and 4.
上記電源ジャック本体２の溝１７に保護カバー１８の障
壁１９が嵌合するように取り付けられる為、−次側端子
７と二次側端子中量も一次側に近い端子８との間の絶縁
距離を確保する構造となっている。Since the barrier 19 of the protective cover 18 is installed so as to fit into the groove 17 of the power jack main body 2, the insulation distance between the - secondary terminal 7 and the secondary terminal 8 is also close to the primary side. The structure is designed to ensure that
この時、溝１７を端子６側まで延長し、障壁１９が一次
端端子６，７の両方を覆う構造としてしまうと、−次側
端子６，７相互間の絶縁距離不足が生じる恐れがある為
溝１７は、−次側端子と二次側端子が最も近い位置にあ
る片側のみとした。At this time, if the groove 17 is extended to the terminal 6 side and the barrier 19 is structured to cover both the primary end terminals 6 and 7, there is a risk that the insulation distance between the -next end terminals 6 and 7 will be insufficient. The groove 17 was formed only on one side where the negative side terminal and the secondary side terminal were closest to each other.
