随着技术的发展，各式各样的电子设备已被广泛应用于人们的生活、工作和学习中，并为人们的生活、工作和学习带来极大的方便。
电子设备的使用需要用电，一般来说，现有的电子设备的电源大多由内置的电池或者外部电源(如市电)提供。其中，对于接外部电源的情况，由于其电压一般比内置的电池的电压高，因此如果电子设备发生短路，则可能会对电子设备和用户造成伤害。
为了防止电子设备发生短路而引起的安全隐患，现有技术通常是在电子设备内安装保险丝，在发生短路时，保险丝自动熔断，从而线路断路。但是保险丝属于一次性消耗产品，其在自动熔断后需要更换，否则电子设备无法正常使用。此外，保险丝有使用寿命，其使用寿命到了后容易失效或失灵，因此还需要定时进行更换，这些都给用户的使用带来了不便。

附图说明
为了更清楚地说明本发明的技术方案，下面将对实施方式中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施方式，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。

图6是本发明实施例提供的公插座的另一种结构示意图。
具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参阅图1及图2，本发明实施例提供了一种公插座100，所述公插座100可固定于电子设备内，如图2所示的母插座200可接入所述公插座100以为所述电子设备供电。
具体地，所述公插座100包括插座本体10、插针20、呈长条状的电磁铁40及第一导线50，所述插座本体上具有插槽11，所述插针20插接于所述插槽11中，所述插槽11具有第一底壁12；所述电磁铁40设置于所述第一底壁12的外侧，所述第一导线50按预定的方向缠绕所述电磁铁40后与所述插针20相电连接，且所述电磁铁40与所述插针20平行。
在本实用实施例中，所述插针20的一端可穿过所述第一底壁12，并露出于所述插座本体10的外部，也可设置于所述第一底壁12内部，本发明不做具体限定。
在本发明实施例中，所述母插头200包括插接头210及第二磁铁220，所述插接头210上设置有插接孔(图未示)，所述插接孔内设置有导电片211，所述导电片211连接有第二导线(图未示)，所述第二磁铁220固定于所述插接头210的设置有所述导电片211的一侧。其中，所述第二磁铁220可通过注塑的方式直接固定在所述插接头210的所述一侧，当然也可通过其他方式进行固定，本发明不做具体限定。
需要说明的是，在本发明实施例中，对于二相的公插座，所述插针20的数目为两个，则相应的，所述母插头200上的插接孔的数目也为两个。
此外，除二相的公插座外，本发明实施例也适用于三相公插座，此时，所述插针20的数目为三个，则相应的，所述母插头200上的插接孔的数目也为三个。
需要说明的是，在本发明实施例中，缠绕所述电磁铁40的第一导线50为所述电路的火线。
在本发明实施例中，所述公插座100与所述母插头200可相互配合安装，且以所述电磁铁40与所述第一底壁12相互靠近的一端为接近端41，所述电磁铁40与所述第一底壁12相 互远离的另一端为远离端42；以所述第二磁铁220与所述导电片211相互靠近的一端为接近端221，所述第二磁铁220与所述导电片211相互远离的另一端为远离端222；在通电后，所述电磁铁40的接近端41与所述第二磁铁220的接近端221的极性相同。
具体地，在本发明实施例中，当所述母插头200插入所述公插座100内时，所述插接头210接入所述插槽11内，且所述插针20插入对应的所述插接孔并与所述导电片211连接。当所述母插头200接入电源(如市电)时，所述第一导线50内有电流流过，根据安培定则，所述电磁铁40将产生与电流大小相对应的磁场，且磁场的方向与电流的关系如图1所示，此时，所述电磁铁40的接近端41的磁极为N极，所述电磁铁40的远离端42的磁极为S级。则相应的，如图2所示，位于所述母插头200内的第二磁铁220的接近端221的磁极为N极，所述第二磁铁220的远离端222的磁极为S极。根据同性相斥原理，所述母插头200与所述公插座100之间存在相互排斥的斥力F1。当电流不是特别大时，这个斥力F1小于所述母插头200与所述公插座100之间的结合力F2(如由二者紧密接触而形成的摩擦力)，因此不足以使得所述母插头200与所述公插座100分离，所述母插头200与所述公插座100可正常连接并通电。
当所述电子设备内部发生短路时，所述第一导线50内流过的电流将变得非常大，此时，所述电磁铁40产生的磁场的强度也增大，并使得所述母插头200与所述公插座100之间产生的斥力F1远大于所述母插头200与所述公插座100之间的结合力F2，此时，所述母插头200将被迅速弹开，如此，所述母插头200与所述公插座100自动分离，整个电路断路，从而避免了由于短路造成对所述电子设备的损害。
需要说明的是，在本发明实施例中，由于所述电磁铁40与所述插针20平行，如此，斥力F1的方向与结合力F2的方向在同一直线上，保证所述母插头200被正确的弹开。
需要说明的是，在本发明实施例中，所述电磁铁40通电后的N极的方向由所述第一导线50的缠绕方向(或电流的方向)决定，当所述第一导线50以另一个方向缠绕时，则N极和S极的方向对调，此时，相应的，所述第二磁铁220的放置方向也相应调整。
综上所述，本发明实施例提供的公插座100，通过所述电磁铁40与所述母插头200内的第二磁铁220的配合，可在所述电子设备内部发生短路的时候，通过机械方式自动弹开所述母插头200，从而快速的从源头切断电路，避免了因短路对电子设备造成的损害。此外，在经过电路排查检修后，可在不需要由专业人员额外更换保险丝或其他保护元件的情况下，直接再次进行使用，方便了用户的操作。
为了便于对本发明的理解，下面将对本发明的一些优选实施例做更进一步的描述。
请一并参阅图3，优选地，在本发明实施例中，为了防止正常通电时，由于所述母插头200与所述公插座100之间的斥力F1而导致二者连接不稳定而造成自动断路，所述插座本体10内还固定有第一磁铁70，且所述第一磁铁70与所述电磁铁40的相互靠近的两端的磁极相同，即以所述第一磁铁70与所述第一底壁12相互靠近的一端为接近端，所述第一磁铁70与所述第一底壁12相互远离的另一端为远离端，在通电后，所述第一磁铁70的接近端与所述电磁铁40的接近端41的极性相同。这样，根据同性相吸的原理，所述第一磁铁70与所述第二磁铁220之间将产生引力F3，保证所述母插头200与所述公插座100牢固的连接。当然，应当注意的是，这个引力F3应当适当，以避免在短路时，所述母插头200无法被弹开，即要求在发生短路时，F1＞F2+F3。
需要说明的是，所述第一磁铁70可固定于所述插槽11的槽面上(如设置在所述槽面的两侧)，其中，在所述母插头200插入所述公插座100时，所述母插头200可与所述槽面相接触，这样，就使得所述第一磁铁70与位于所述母插头200内的第二磁铁220具有较短的距离，保证可以获得足够的引力F3。
优选地，请一并参阅图4，对于所述母插头200与所述公插座100之间结合力F2较大的情况，为了防止不能快速的将所述母插头200弹开而造成对所述电子设备的损害，所述底壁12的内侧还可固定有弹簧80。当所述母插头200插入所述公插座100内时，所述弹簧80被压缩并产生弹力F4，这个弹力F4的方向与所述公插座100对所述母插头200的斥力的方向相同。如此在发生短路时，由于所述弹力F4的存在，可更快速有力的将所述母插头200弹开。当然，为了防止所述母插头200与所述公插座100在正常状况下无法正常连接，所述弹簧80的长度和弹性系数应适当设计，如需满足在正常通电时：F1+F4＜F2，而在短路时：F1+F4＞F2。
优选地，请一并参阅图5，结合上述两个优选实施例，即同时在所述公插座200上设置所述第一磁铁70及所述弹簧80，还可起到防止小朋友误将所述母插头200插入到所述公插座100上的目的。具体地，由于所述弹簧80的存在，在将所述母插头200插入到所述公插座100内时，需要用力克服所述弹簧80的弹力F4(小朋友没有足够的力气来克服这个弹力F4)，而由于所述第一磁铁70的存在，又可以使得所述母插头200在完全插入所述公插座100内时(此时，所述第一磁铁70与所述第二磁铁220距离拉近，二者的引力F3最大)，所述母插头200不会被所述弹簧80弹开。这样就避免了小朋友误将所述母插头200插入到所述公插座100上而导致的安全隐患。当然，为了防止所述母插头200与所述公插座100在正常状况下无法正常连接，应满足在正常通电时：F1+F4＜F2+F3；而在短路时，F1+F4＞F2+F3。
优选地，在本发明实施例中，为了避免所述电磁铁40对所述电子设备内的其他元件造成影响，如图6所示，所述公插座100还包括连接在所述第一底壁12上的磁场屏蔽层90，所述电磁铁40固定于所述磁场屏蔽层90内。具体地，所述磁场屏蔽层90为一面开口，且所述磁场屏蔽层90的开口面连接所述第一底壁12的外侧壁，当所述电磁铁40放置于所述磁场屏蔽层90内时，其两侧的磁感应线会进入所述壳体内，而不会泄露到外部，进而不会对所述电子设备内的其他铁磁元件造成影响。其中，所述磁场屏蔽层90可为由铁磁材料制成的壳体，如铁、钴、镍等材料制成的壳体。
本发明还提供一种与所述公插座100对应的母插座200，其具体结构及工作原理已在上述实施例中进行了详细的描述，本发明在此不做赘述。
本发明还提供一种具有所述公插座100的电子设备，所述电子设备可为生活、工作、学习中的电子设备，如微波炉、电脑、打印机等，本发明不做具体限定。
本发明还提供一种接插件，所述接插件包括上述任一实施例所述的公插座100及母插头200；所述公插座100与所述母插头200相互配合安装，且在通电后，所述电磁铁40的接近端41与所述第二磁铁220的接近端221的极性相同。
综上所述，本发明实施例提供的公插座100、母插头200、电子设备及接插件，通过所述公插座100内的电磁铁40与所述母插头200内的第二磁铁220的配合，可在所述电子设备发生短路的时候，通过机械方式自动弹开所述母插头200，从而快速的从源头切断电路，避免了因短路对所述电子设备造成的损害。此外，在经过对电子设备的电路进行排查检修后，可在不需要由专业人员更换保险丝或其他相应保护元件的情况下，直接再次进行使用，方便了用户的操作。
以上所揭露的仅为本发明一种较佳实施例而已，当然不能以此来限定本发明之权利范围，本领域普通技术人员可以理解实现上述实施例的全部或部分流程，并依本发明权利要求所作的等同变化，仍属于发明所涵盖的范围。
本领域普通技术人员可以理解实现上述实施例方法中的全部或部分流程，是可以通过计算机程序来指令相关的硬件来完成，所述的程序可存储于一计算机可读取存储介质中，该程序在执行时，可包括如上述各方法的实施例的流程。其中，所述的存储介质可为磁碟、光盘、只读存储记忆体(Read-Only Memory，ROM)或随机存储记忆体(Random Access Memory，RAM)等。
