具体实施方式
下面结合具体实施例和说明书附图对本实用新型做进一步阐述和说明:
请参考图1，一种电源适配器包括本体10和转换插头20。
请参考图2和图3，本体10包括第一插接部11，转换插头20包括第二插接部21，第二插接部21与第一插接部11插接并导通。
请参考图2、图3和图4，本体10内设有锁紧件12，锁紧件12包括锁舌121。本体10上开设有供锁舌121伸出的第一卡孔13，转换插头20上设有与第一卡孔13相对的第二卡孔22。其中，第一插接部11的插接方向与锁舌121的伸出方向不同。优选的，第一插接部11的插接方向为竖直方向，锁舌121的伸出方向为水平方向。
使用时，使本体10与转换插头20通过第二插接部21与第一插接部11进行插接连接并导通。锁紧件12的锁舌121伸出第一卡孔13并伸入转换插头20的第二卡孔22内。由于第一插接部11的插接方向与锁舌121的伸出方向不同，使得第一插接部11的退回被锁舌121限制，从而使得本体10与转换插头20的连接稳定可靠。
请参考图2、图3和图5，上述方案中，第一插接部11为插槽，第一插接部11内设有插针111。第二插接部21为插接头，第二插接部21底面形成有与插针111对应的插孔211。插孔211内设有导电片，导电片与转换插头20的插脚电连接。
具体的，第一插接部11为腰形槽，第一插接部11内壁的长边向内突出形成限位块112。第二插接部21外壁形成与限位块112相对的限位槽212。限位块112使得第一插接部11的两侧长边不对称，从而限制第二插接部21插入的方向。
应当理解的是，第一插接部11也可为插接头，第二插接部21为对应的插槽。
请参考图4和图6，锁紧件12还包括滑键122以及弹力件123。滑键122可滑动的设于本体10，锁舌121设于滑键122。弹力件123一端抵接于锁舌121，另一端抵接于本体10内壁，弹力件123用于提供保持锁舌121伸出第一卡孔13的力。请参考图8，转换插头20上开设有避让槽23，避免转换插头20影响锁紧件12的滑动。
请参考图4和图6，锁舌121包括连接部1211、杆部1212和舌部1213，杆部1212和舌部1213分设于连接部1211的相对两侧面，弹力件123套设于杆部1212，连接部1211上开设开口槽1214，滑键122卡入开口槽1214中。具体的，连接部1211为L形板体，开口槽1214的开口方向与滑键122的滑动方向垂直。
请参考图2和图4，本体10一侧凹陷形成安装槽14，转换插头20容置于安装槽14内。第一插接部11设于安装槽14底面，第一卡孔13设于安装槽14侧面。第二插接部21设于转换插头20底面，第二卡孔设于转换插头20侧面。插接时，使转换插头20底面与安装槽14底面相对，将第二插接部21插入第一插接部11内。第一插接部11内的插针111与电路板电连接，所述本体10上设有USB以及Type-C，所述USB和Type-C均与电路板电连接。
安装槽14具体形成在本体10的拐角位置。安装槽14包括底面和侧面，安装槽14的底面和侧面一体成型，本体10上形成卡槽15，安装槽14的底面和侧面卡设于卡槽15内。
请参考图7、图8、图9和图10，该本体10上设有不同地区和国家的转换插头20。
最后应当说明的是，以上实施例仅用以说明本实用新型的技术方案，而非对本实用新型保护范围的限制，尽管参照较佳实施例对本实用新型作了详细地说明，本领域的普通技术人员应当理解，可以对本实用新型的技术方案进行修改或者等同替换，而不脱离本实用新型技术方案的实质和范围。
