技术领域
本发明涉及连接器技术领域，更具体地说，涉及一种电磁吸式金属连接器。
背景技术
随着电子技术的发展，智能手机、平板电脑、游戏掌机以及智能可穿戴设备等智能电子产品越发普及。
智能电子产品通常需要通过连接器进行充电和数据传输，部分产品为提高用户体验或受限于特殊使用场景会采用磁吸式连接器，以实现便利连接。
现有的磁吸式连接器多为在连接器母端中设置永磁体或充磁介质，以此达到磁吸目的，因此连接器的尺寸较大且内部结构简单、功能单一，端子和PIN针数量很少。
综上所述，如何提供一种结构紧凑、生产成本低、端子和PIN数量较多的磁吸式连接器，是目前本领域技术人员亟待解决的问题。
发明内容
有鉴于此，本发明的目的是提供一种电磁吸式金属连接器，在金属连接器母端外环绕设置有导电线圈，导电线圈通电后产生电磁场、进行磁吸，因此内部结构紧凑、对端子和PIN针数量无限制且降低了制造成本。
为了实现上述目的，本发明提供如下技术方案：
一种电磁吸式金属连接器，包括母端连接器和与其配合的公端连接器，所述母端连接器包括外壳，所述外壳内设有金属连接器母端、环绕所述金属连接器母端设置的导电线圈以及PCB板，所述金属连接器母端和所述导电线圈均与所述PCB板连接，以便为二者导通通电；
所述导电线圈与所述金属连接器母端完全绝缘不导通。
优选的，所述导电线圈缠绕设置或套装于所述金属连接器母端的外壁面上。
优选的，所述导电线圈上设有两个与所述PCB板连接的焊针，所述PCB板上设有与所述焊针配合的焊孔。
优选的，所述焊针设置于所述导电线圈宽度方向上的两端。
优选的，所述焊针与所述焊孔插接，且所述焊针的头部凸出所述PCB板的底面设置，所述焊针凸出所述PCB板底面的部分与所述PCB板焊接连接。
优选的，所述导电线圈由导电线材绕制而成，且所述导电线材的表面设有绝缘材料层。
本发明提供的电磁吸式金属连接器，包括母端连接器和与其配合的公端连接器，母端连接器包括外壳，外壳内设有金属连接器母端、环绕金属连接器母端设置的导电线圈以及PCB板，金属连接器母端和导电线圈均与PCB板连接，以便为二者导通通电；导电线圈与金属连接器母端完全绝缘不导通。
导电线圈与PCB板导通通电后，依据电流的磁效应导电线圈形成电磁场并磁化金属连接器母端，金属连接器母端磁化形成的磁场与导电线圈的磁场叠加，使得磁性大为增强，实现对公端连接器的磁吸功能。
相比于现有技术中的永磁体或充磁介质，导电线圈的体积小，使得金属连接器整体结构紧凑；同时导电线圈环绕设置于金属连接器母端外，对金属连接器母端的内部结构无影响，对其端子和PIN数量无限制，有利于金属连接器多功能要求的实现。
此外，导电线圈相较于永磁体或充磁介质具有显著的成本优势，显著降低了磁吸式金属连接器的生产成本。
