本实施例一中， 所述插头有四组， 分别为 BS英规插头 80、 UL美规插头 81、 VDE欧规插 头 82和 SAA澳规插头 83, 对应地， 导轨 60和弹簧 61有四根， 总定位开关 50上成型有四根 定位爪 52 , 拨动按钮 70有四个， 导槽 11有四条。 如图 1和图 2所示， 本实施例一中， 所述 插座输出部分与插头输入部分可拆卸分离； 插座输出部分包括插座底壳 90和插座面壳 92 , 插头面壳 20上端成型有 G3坑 21 , 插座底壳 90卡装于所述 G3坑 21 内； 所述插座输出部分的 输出接口为英规 BS式、 美规 UL式、 欧规 VDE式和澳规 SAA式这四种规格插座孔的组合， 四 种规格插座孔的组合开设在插座面壳 92上， 插座底壳内部设有相应的第二导电极片组 93与 第一导电极片组 30电连接。
当然， 本实用新型中， 插头的组合也可以是 BS英规插头 80、 UL美规插头 81、 VDE欧规 插头 82和 SAA澳规插头 83这四种中的任意两种或三种的组合设计， 相应对导轨 60、 弹簧 51 和总定位开关 50的定位爪 52、 以及拨动按钮 70及导槽 11进行适配调整设计即可， 插座输 出部分的输出接口可根据需求做单独或组合的接口进行设计。
下面结合图 3至图 12简要说明下本实用新型电源适配器实施例一的各组插头相互切换 的原理及过程。
为了方便描述和理解起见， 下述中， 定义： BS英规插头 80的定位块为第一定位块 801 , 对应的定位口为第一定位口 521 , UL美规插头 81的定位块为第二定位块 811 , 对应的定位口 为第二定位口 522 , VDE欧规插头 82的定位块为第三定位块 821 , 对应的定位口为第三定位 口 523, SAA澳规插头 83的定位块为第四定位块 831 , 对应的定位口为第四定位口 524。
初始时， 如图 3所示， 示意的是四组插头都处于容置空间内也即未使用时的初始状态， 图中相对侧重表示出欧规 VDE式插头 82的初始状态； 欲使用欧规 VDE式插头 82时， 参见图 4, 向下推动其对应的拨动按钮 70, 欧规 VDE式插头 82 向下移动， 同时总定位开关 50向图 示方向的左边稍微移动， 直至第三定位块 821被第三定位口 523抵住， 此时， 总定位开关 50 在复位弹簧 51的作用下向图示方向的右边回移复位， 欧规 VDE式插头 82即被伸出锁定。
图 5至图 7示意出欧规 VDE式插头 82与英规 BS式插头 80的切换过程， 图 5示意的是 欧规 VDE式插头伸出而英规 BS式插头处于初始状态， 欲切换到英规 BS式插头 80时， 参见图 6 , 向下推动英规 BS式插头 80对应的拨动按钮 70 , 英规 BS式插头 80向下移动， 同时总定 位开关 50 向图示方向的左边稍微移动， 导致第三定位块 821 与第三定位口 523脱离， 欧规 VDE式插头 82在弹簧 61的作用下向上移动回缩， 继续向下推动拨动按钮， 直至第一定位块 801被第一定位口 521抵住， 此时， 总定位开关 50在复位弹簧 51的作用下向图示方向的右 边回移复位， 英规 BS式插头 80完全伸出即被锁定， 而欧规 VDE式插头 82完全缩回， 此时如 图 7所示。
图 8至图 10示意出英规 BS式插头 80与美规 UL式插头 81的切换过程， 图 8示意的是 英规 BS式插头 80伸出而美规 UL式插头 81处于初始状态， 欲切换到美规 UL式插头 81时， 参见图 9 , 向下推动美规 UL式插头 81对应的拨动按钮 70 , 美规 UL式插头 81向下移动， 同 时总定位开关 50向图示方向的左边稍微移动， 导致第一定位块 801与第一定位口 521脱离， 英规 BS式插头 80在弹簧 61的作用下向上移动回缩， 继续向下推动拨动按钮， 直至第二定位 块 811被第二定位口 522抵住， 此时， 总定位开关 50在复位弹簧 51的作用下向图示方向的 右边回移复位， 美规 UL式插头 81完全伸出即被锁定， 而英规 BS式插头 80完全缩回， 此时 如图 10所示。
图 11和图 12示意出美规 UL式插头 81与澳规 SAA式插头 83的切换过程，图 11示意的 是美规 UL式插头 81伸出而澳规 SAA式插头 83处于初始状态， 参见图 12 , 欲切换到澳规 SAA 式插头 83时， 向下推动澳规 SAA式插头 83对应的拨动按钮 70 , 澳规 SAA式插头 83向下移 动， 同时总定位开关 50向图示方向的右边稍微移动， 导致第二定位块 811与第二定位口 522 脱离， 美规 UL式插头 81在弹簧 61的作用下向上移动回缩， 继续向下推动拨动按钮， 直至第 四定位块 831被第四定位口 524抵住， 此时， 总定位开关 50在复位弹簧 51的作用下向图示 方向的左边回移复位，澳规 SAA式插头 83完全伸出即被锁定，而美规 UL式插头 81完全缩回。
诚然， 本实用新型中， 各组插头之间的切换不限于上述的欧规 VDE式插头 82与英规 BS 式插头 80、 英规 BS式插头 80与美规 UL式插头 81、 美规 UL式插头 81与澳规 SAA式插头 83 这几种切换方式。 只要其中一组插头处于伸出工作状态时， 内部的其它三组插头可以任一选 择进行切换， 具体此处就不再赘述。
当需要将所有插头都缩回时，选择内部任一组插头对应的拨动按钮，稍微推动一段行程 使伸出在外的插头自动缩回， 然后不再推动拨动按钮即可。
实施例二：
本实用新型电源适配器实施例二， 如图 1 3所示， 该实施例二与实施例一结构和原理基 本相同， 不同之处在于： 所述插座输出部分与插头输入部分的插头面壳 20—体成型， 也即插 头面壳 20同时兼作插座外壳， 其它此处不再赘述。
实施例三：
本实用新型电源适配器实施例三， 如图 14所示， 该实施例三与实施例二结构和原理基 本相同， 不同之处在于： 所述插座输出部分的输出接口为 USB接口 100 , 其通过插座输出部 分内部的变压电路与第一导电极片组 30电连接。 需要说明的是， 相对插座孔而言， 釆用 USB 接口 100需要增设变压电路和接口转换， 图中未画出， 这样， 本实用新型能够作为充电器直 接输出低压直流电， 与 USB连接线直接对接， 这些都是成熟的现有技术， 此处不再赘述。
实施例四：
本实用新型电源适配器实施例四， 如图 15所示， 该实施例四与实施例一和实施例三的 结构和原理基本相同， 与实施例一的不同之处在于： 所述插座输出部分的输出接口为 USB接 口， 开设在插座面壳 20上； 所述 USB接口通过插座底壳内部的变压电路与第一导电极片组电 连接。 与实施例三的不同之处在于： 所述插座输出部分与插头输入部分可拆卸分离， USB 接 口 100开设在插座面壳 20上。 其它此处不再赘述。
以上内容是结合具体的优选技术方案对本实用新型所作的进一步详细说明，不能认定本 实用新型的具体实施只局限于这些说明。对于本实用新型所属技术领域的普通技术人员来说， 在不脱离本实用新型构思的前提下， 还可以做出若干简单推演或替换， 都应当视为属于本实 用新型的保护范围。
