具体实施方式
图2为本实用新型一实施方式中节能适配器10与用电设备20的示意图。 在本实施方式中，节能适配器10连接于电源30与用电设备20之间，用于转换电源30的电源信号，为用电设备20供电。节能适配器10包括直流插头100、电源转换电路110、以及磁性开关120。用电设备20包括插孔200，插孔200包括磁性元件202。在本实施方式中，磁性元件202为磁铁。 
电源转换电路110用于转换电源30的电源信号为用电设备20需要的信号，以给用电设备20供电。直流插头100与电源转换电路110相连，并与用电设备20的插孔200相配合，用于传输电源转换电路110转换后的电源信号至用电设备20，使用电设备20工作。直流插头100包括磁力传导线，用于在用电设备20用电时，传导用电设备20的磁性元件202的磁力至磁性开关120。在本实施方式中，用电设备20的磁性元件202位于插孔200内，当用电设备20用电时，直流插头100插入插孔200内，磁力传导线与磁性元件202接触，因而磁力传导线传导磁力。而当用电设备20不使用时，直流插头100从插孔200内拔出，磁力传导线不与磁性元件202接触，因而磁力传导线无磁力传导。在本实施方式中，磁力传导线附着于直流插头100的地线上，其为铁线。 
磁性开关120连接于电源30与电源转换电路110之间，用于根据磁力传导线是否传导磁力而开关，从而控制电源30给电源转换电路110供电。图4与图5所示为磁性开关120的连接关系的不同实施方式，其中，电源30都包括交流电源300及直流电源310。交流电源300为110/220V的市电，直流电源310为电源转换电路110提供工作电压，使之将交流电源300的110/220V的电源信号转换成直流电源信号，然后给用电设备20供电。在本实施方式中，磁性开关120为微型磁簧继电器或其他感磁元件。 
如图4所示，交流电源300连接于电源转换电路110，直流电源310经磁性开关120连接至电源转换电路110。如此，当用电设备20用电时，直流插头100插入插孔200内，磁力传导线传导磁力至磁性开关120，使磁性开关120闭合。此时，直流电源310为电源转换电路110供电，使其将交流电源300转换成直流电源信号，为用电设备20供电。而当用电设备20不使用时，直流插头100从插孔200内拔出，因而磁力传导线无磁力传导，磁性开关120断开。此时，直流电源310不为电源转换电路110供电，电源转换电路110不进行工作。因而，大大降低了未使用时的节能适配器10的功耗，符合现在能源节约的 发展趋势。 
在本实用新型的另一实施方式中，如图5所示，直流电源310连接于电源转换电路110，交流电源300经磁性开关120连接至电源转换电路110。当用电设备20用电时，直流插头100插入插孔200内，磁力传导线传导磁力至磁性开关120，使磁性开关120闭合。此时，直流电源310为电源转换电路110供电，交流电源300为电源转换电路110提供转换所需的交流电源信号，以转换成直流电源信号，为用电设备20供电。而当用电设备20不使用时，直流插头100从插孔200内拔出，因而磁力传导线无磁力传导，磁性开关120断开。此时，交流电源300不为电源转换电路110提供转换所需的交流电源讯号，电源转换电路110几乎无功率损耗，比图4中未使用时的功耗更低，达到节能环保的目的。 
图3所示为本实用新型另一实施方式中节能适配器10与用电设备20’的示意图。在本实施方式中，节能适配器10与图2中的相同，且磁性开关120的连接位置也包括图4与图5两种实施方式。在本实施方式中，用电设备20’包括开关204，与插孔200相连，开关204包括磁性元件202。当使用者使用用电设备20’时，即用电设备20’用电时，开关204闭合。磁性元件202的磁力通过插孔200及磁力传导线传导磁力至磁性开关120，使磁性开关120闭合。此时，直流电源310为电源转换电路110供电，使其将交流电源300转换成直流电源信号，为用电设备20供电。而当用电设备20不使用时，使用者断开开关204。磁性元件202与插孔200断开连接，因而磁力传导线无磁力传导，磁性开关120断开。此时，电源转换电路110不进行工作，因而，大大降低了未使用时的节能适配器10的功耗，符合现在能源节约的发展趋势。 
图2至图5所示的电源转换电路110包括控制芯片，如脉宽调制(PWM)控制器，该控制芯片包括电源接脚、使能接脚等，磁性开关120可连接在控制芯片的电源接脚与使能接脚的任意一个。 
本实用新型的节能适配器10利用磁性开关120与磁力传导线进行用电设备20、20’是否用电的判断，在用电设备20、20’不用电时，磁性开关120断开，从而中断电源30与节能适配器10的连接，减少节能适配器10的功耗。另外，节能适配器10的原有电路设计不需更改，设计成本较低。此外，磁性开关120不需实体接触，符合安规规范。
