本发明提出一种电源线，该电源线具有漏电检测导体，以方便将该电源线应用于具有漏电自检功能的电源线组件中。
如图1和2所示，该电源线包括第一导线10、第二导线20、第一导电粉末层61、第二导电粉末层62、绝缘件40和漏电检测导体50。其中，第一导线10包括第一载流芯11和包裹在第一载流芯11外侧壁上的第一绝缘层12，第二导线20包括第二载流芯21和包裹在第二载流芯21外侧壁上的第二绝缘层22；第一导电粉末层61包裹于第一绝缘层12的外侧壁上；第二导电粉末层62包裹于第二绝缘层22的外侧壁上；绝缘件40具有第一容置腔41，漏电检测导体50设于第一容置腔41内，具有第一导电粉末层61的第一导线10和具有第二导电粉末层62的第二导线20设于第一容置腔41内，所述容置件70设于所述第一容置腔41内，所述容置件具有第二容置腔71，所述第一导线10和第二导线20设于所述第二容置腔内，所述容置件70具有导电性，且所 述容置件70与所述第一导电粉末层61和所述第二导电粉末层62电连接；漏电检测导体50设于第二容置腔71内，漏电检测导体50与容置件70电连接。
如图1和2所示，当第一绝缘层12和/或第二绝缘层22受损时，第一载流芯11和/或第二载流芯21就会从第一绝缘层12和/或第二绝缘层22的受损处产生漏电问题，而本发明通过在第一绝缘层12的外侧壁和第二绝缘层22的外侧壁上分别对应包裹第一导电粉末层61和第二导电粉末层62，使得第一载流芯11和/或第二载流芯21在第一绝缘层12和/或第二绝缘层22的受损处与第一导电粉末层61和/或第二导电粉末层62接触，而第一导电粉末层61和第二导电粉末层62又是与容置件70电连接的，且容置件70与漏电检测导体50电连接，如此，漏电检测导体50能够准确、及时地发现第一导线10和第二导线20的漏电现象，然后通过脱扣机构及时地断开电源，考虑到本发明中漏电检测导体50一般是检测到电压或电流变化，上述脱扣机构可优选为电磁脱扣机构。
由于本发明中的第一导电粉末层61和第二导电粉末层62是粉末状的结构，如此，当第一绝缘层12和/或第二绝缘层22受损时，且在该破损仅仅是微小的破损裂纹时，第一导电粉末层61和/或第二导电粉末层62也会进入该受损的地方与第一载流芯11和/或第二载流芯21接触，从而能够非常及时地发现第一导线10和第二导线20的漏电现象。
值得一提的是，该第一导线10和第二导线20通常是电源线中的火线和零线，如此，本发明中的电源线可有效防止第一导线10和第二导线20同时产生漏电而导致的短路问题，以防发生火灾；或者第一导线10和/或第二导线20产生漏电现象，且绝缘件40也破损时，导致电源线对外漏电的问题，以防引起人畜触电。
优选地，如图1和2所示，还包括：容置件70，容置件70具有导电性，容置件70设置在第一容置腔41内，形成第二容置腔71，其中，具有第一导电粉末层61的第一导线10和具有第二导电粉末层62的第二导线20设置在第二容置腔71内，并且第一导电粉末层61和第二导电粉末层62中的至少一个与第二容置腔71电连接，并且漏电检测导体50与容置件70电连接，从而，当第一绝缘层12和/或第二绝缘层22受损时，第一载流芯11和/或第二载流芯21要想从绝缘件40向电源线外产生漏电，必然会与容置件70接触，容置件70与漏电检测导体50电连 接，漏电检测导体50能够准确、及时地发现第一导线10和第二导线20的漏电现象，从而保证了漏电检测的准确性和及时性。
优选地，如图1和2所示，将第一导线10和第二导线20设于所述第二容置腔71内，如此，当第一绝缘层12和/或第二绝缘层22受损时，第一载流芯11和/或第二载流芯21要想从绝缘件40向电源线外产生漏电，必然会与漏电检测导体50接触，从而保证了漏电检测的准确性和及时性。具体地，可设置漏电检测导体50的内侧壁与第一导电粉末层61和第二导电粉末层62接触，以实现漏电检测导体50与第一导电粉末层61和第二导电粉末层62的电连接。
优选地，如图3至5所示，漏电检测导体50设于第一容置腔41内，漏电检测导体50具有第三容置腔80，其中，具有第一导电粉末层61的第一导线10和具有第二导电粉末层62的第二导线20设置在第三容置腔80内，并且第一导电粉末层61和第二导电粉末层62中的至少一个与漏电检测导体50电连接。当第一绝缘层12和/或第二绝缘层22受损，第一载流芯11和/或第二载流芯21就会从第一绝缘层12和/或第二绝缘层22的受损处产生漏电问题时，本发明通过在第一绝缘层12的外侧壁和第二绝缘层22的外侧壁上分别对应包裹第一导电粉末层61和第二导电粉末层62，使得第一载流芯11和/或第二载流芯21在第一绝缘层12和/或第二绝缘层22的受损处与第一导电粉末层61和/或第二导电粉末层62接触，而第一导电粉末层61和第二导电粉末层62又是与漏电检测导体50电连接的，从而，漏电检测导体50能够准确、及时地发现第一导线10和第二导线20的漏电现象，然后通过脱扣机构及时地断开电源。
当然，如图5所示，在本发明的实施例中，也可将第一导线10和第二导线20设于所述第二容置腔71外。具体地，可设置漏电检测导体50的外侧壁与第一导电粉末层61和第二导电粉末层62接触，以实现漏电检测导体50与第一导电粉末层61和第二导电粉末层62的电连接。
优选地，如图6和7所示，在本发明的实施例中，也可将容置件70设于第一容置腔41内，容置件70具有第二容置腔71，第一导线10和第二导线20设于第二容置腔71内，容置件70与第一导电粉末层61和第二导电粉末层62电连接；漏电检测导体50设于第二容置腔71外侧，并与容置件70电连接。当第一绝缘层12和/或第二绝缘层22受损时，第一载流芯11和/或第二载流芯21就会从第一绝缘层12和/或第二绝缘层22的受损处产生漏电问题，而本发 明通过在第一绝缘层12的外侧壁和第二绝缘层22的外侧壁上分别对应包裹第一导电粉末层61和第二导电粉末层62，使得第一载流芯11和/或第二载流芯21在第一绝缘层12和/或第二绝缘层22的受损处与第一导电粉末层61和/或第二导电粉末层62接触，而第一导电粉末层61和第二导电粉末层62是与容置件70电连接的，且容置件70又是与漏电检测导体50电连接的，如此，漏电检测导体50能够准确、及时地发现第一导线10和第二导线20的漏电现象。
如图1至5所示，为了提高电源线的漏电检测性能，设置第一导电粉末层61和第二导电粉末层62接触，如此，只需设置第一导电粉末层61和第二导电粉末层62中任一个与漏电检测导体50接触，即可实现以实现漏电检测导体50与第一导电粉末层61和第二导电粉末层62的电连接，如图4所示，第一导电粉末层61与漏电检测导体50接触。当然也可设置漏电检测导体50与第一导电粉末层61和第二导电粉末层62同时接触，如图3所示，如此，可以提供多重保障，保证了漏电检测导体50与第一导电粉末层61和第二导电粉末层62电连接的稳定性，有效提高本发明中电源线的漏电检测性能。
优选地，本发明中第一导电粉末层61和第二导电粉末层62为石墨粉末层或金属粉末层。由于石墨粉具有良好的化学稳定性、耐高温性、高吸附性和密度小的特点，因此本发明中的第一导电粉末层61和第二导电粉末层62可优选为石墨粉。
具体的，设置石墨粉末层静电吸附于第一绝缘层12和/或第二绝缘层22的外壁上，如此，可将石墨粉稳定地吸附于第一绝缘层12和/或第二绝缘层22的外壁上，从而保证了电源线结构和性能的稳定性。当然，在其他实施例中，也可设置金属粉末层电镀于第一绝缘层12和/或第二绝缘层22的外壁上，如此，可实现金属粉末层稳定地附着于第一绝缘层12和/或第二绝缘层22的外壁上，从而保证电源线结构和性能的稳定性。
优选地，第一导电粉末层61和第二导电粉末层62接触，这样，只需要第一导电粉末层61和第二导电粉末层62中的任一导电粉末层接触到绝缘层的破损时，漏电检测导体50即可检测到漏电现象，如此，可以提供多重保障，保证第一导电粉末层61和第二导电粉末层电62连接到漏电检测导体50的稳定性，有效提高本发明中电源线的漏电检测性能。
优选地，漏电检测导体50可选择导电线，如铜线或铝线，该结构比较简 单，而且比较实用。为了增强漏电检测的准确性，可设置多根导电线，且设置该多根导电线间隔分布于绝缘件40中。当然，漏电检测导体50也可根据需要设置成其它形状，如片状、块状、环状或管状。
值得一提的是，一般的，本实用新型中的电源线大致上为长条形，且具有卷绕性；第一导线10和第二导线20的两端通常是裸露出第一载流芯11和第二载流芯21的，如此，可方便将该电源线与其它部件组装成一电源线组件。
如图3至7所示，为了加强本发明中漏电检测导体50结构的稳定性，防止其因电源线扭曲而产生错位，导致漏电检测导体50与第一导电粉末层61和/或第二导电粉末层62之间处于非电连接状态，可设置漏电检测导体50与绝缘件40的紧贴设置。具体的，可将漏电检测导体50完全覆盖绝缘件40的内壁设置，如采用粘贴或电镀的方式将漏电检测导体50设置于绝缘件40的内壁上，如此，不仅可以保证电源线结构的稳定性，还可方便电源线的制作。当然，该漏电检测导体50也可包括静电吸附于绝缘件40内壁上的石墨粉末层。
优选地，本发明中设置漏电检测导体50与容置件70紧贴设置，如通过粘贴方式或者其他结构将漏电检测导体50抵接在容置件70的外侧壁实现两者的接触，以实现两者的电连接，该结构比较简单，方便电源线的制作。
具体地，可设置漏电检测导体50夹持在容置件70和绝缘件40之间，如在容置件70与绝缘件40之间紧密接触的情况下，将漏电检测导体50设于两者之间，该结构不尽可提高电源线结构的紧凑性，而且能够保证漏电检测导体50与容置件70的紧密接触，保证了漏电检测导体50与容置件70电连接的稳定性，从而提高了漏电检测的稳定性。当然，在本实用新型的其它实施例中，也可在容置件70的外侧壁上设置夹持漏电检测导体50的凹槽，以实现漏电检测导体50与容置件70的电连接。
优选地，本发明中的漏电检测导体50和/或容置件70可设置为金属层或导电橡胶层。其中，当漏电检测导体50和/或容置件70为金属层时，该漏电检测导体50和/或容置件70可设置为由铜、铁、铝和锡中的一种或多种金属制成，如可将该漏电检测导体50和/或容置件70制成铜箔、铁箔、铝箔或锡箔等金属薄膜，如此，可简化漏电检测导体50和/或容置件70的结构，从而降低电源线的成本。当然，在本发明的其它实施例中，也可设置漏电检测导体50和/或容置件70由合金制成。
如图1至4和图6、7所示，为了加强本发明中电源线的安全性能，保证使用该电源线的电器设备的用电安全，设置本发明中的电源线还包括设于第一容置腔41内的第三导线30，该第三导线30用于接地，该第三导线30包括第三载流芯31和包裹在第三载流芯31外侧壁上的第三绝缘层32，如此，使用该电源线的电器设备的部分金属本体可方便地做到接地保护，防止漏电引起人身安全隐患。
