Description

一种连接器及包括该连接器的便携式设备 技术领域
本发明涉及接口或连接器技术领域，尤其涉及一种连接器及包括该连接器的便携式设备。
背景技术
随智能设备的发展，用户在功能上趋向于更专业化、多样化和智能化的产品。同时，专业的功能模块也需要快速地与智能平台搭接，因而对于智能设备的可扩展性有了更大的需求。但现有的便携式智能设备在可扩展连接上还不能满足需求。在功能上，现有的便携智能设备一般只提供单一的连接接口，提供有限的连接功能，例如一般的智能手机采用数据线连接时，在同一时间充电和数据传输功能中只能使用一种。
发明内容
针对以上技术问题，本发明提出了一种连接器，该连接器可实现充电与数据传输同时进行，功能更强大。
针对以上技术问题，本发明的技术解决方案是，提供一种连接器，该连接器主要包含母头和公头，所述母头包括：连接器壳体；连接器，设在连接器壳体内；多组母头端子，均跨接连在连接器与连接器壳体上，所述母头端子包含母头电源端子与母头信号端子；以及多个母头管脚，所述母头管脚连接在连接器壳体底部并凸出连接器壳体的侧面，且母头管脚与母头端子一一对应；所述公头包括公头壳体，所述公头壳体上设有多组公头端子，所述公头端子包含公头电源端子和公头信号端子，所述公头壳体的一面连接有多个公头管脚，所述公头管脚凸出公头壳体侧面并与公头端子 一一对应；且所述母头和公头形成插接扣合的配合结构。
现有便携智能设备，例如智能手机，其上的接口采用的端子不区分信号端子和电源端子，由于端子的数量有限以及受到惯有的接口设计的影响，一般均采用的是通用的接口。该通用的接口存在的问题是，充电和数据传输时基本共享的是相同的通道，因而在同一时间只能实现充电与数据传输中的一种功能。而本发明的连接器，由于公头包含公头电源端子和公头信号端子、母头包含母头电源端子与母头信号端子，用于电能传输的端子与用于信号传输的端子分开设置，充电与数据传输采用两条不同的通道，因而可实现充电与数据传输同时进行，功能更强大。
在本发明的一个实施例中，所述母头的连接器壳体底部设有保证连接器壳体在第一焊接基板上的定位精度的第一定位结构。在优选的实施例中，所述第一定位结构一般为两个，分别设在连接器壳体的两端。优选地，第一定位结构为圆柱状，在定位时两个定位圆柱分别与第一焊接基板上的两个定位孔配合。
在本发明的一个优选实施例中，所述母头的连接器的两头端面上设有用于插接的导向槽。实际中也可以只在连接器的一头端面设置导向槽，设置两头最主要的好处是，尤其是在全对称的结构下，公头与母头在安装时不需要再对两头进行区分，因而能提高安装效果，降低成本。
在一个优选的实施例中，多个母头端子沿连接器长度方向呈全对称布置。全对称布置的结构有利于安装，有利于降低安装错误率，提高安装效率。
在本发明的其中一个实施例中，所述母头电源端子连接在连接器壳体中部，母头信号端子位于母头电源端子两侧。
在本发明的另一个实施例中，所述母头信号端子连接在连接器壳体中部，母头电源端子分布在连接器壳体靠近两端处，位于母头信号端子两 侧。
在本发明的一个实施例中，所述公头壳体的一端内侧设有凸块，所述公头壳体的另一端靠近公头管脚的一面连接有第二定位结构。在优选的实施例中，所述第二定位结构一般为两个，分别连接在公头壳体靠近公头管脚的一面的两端。优选地，第二定位结构为圆柱状，在定位时两个定位圆柱分别与第二焊接基板上的两个定位孔配合。
在本发明的其中一个实施例中，所述公头电源端子连接在公头壳体中部，公头信号端子分布在公头电源端子的两侧。
在本发明的另一个实施例中，所述公头信号端子设在公头壳体中部，公头电源端子分布在公头信号端子两侧。
另外，本发明还公开了一种便携式设备，该便携式设备的背面设有上述的连接器。由于现有的便携智能设备在接口的位置设置上，一般将接口设置在底面或侧面，而通过数据线在底面或侧面连接时，只能提供有限的空间，使扩展设备的连接受到较大限制。而本发明的便携式设备，是在设备的背面设置上述连接器，这种背面的设置方式不仅解决了空间限制问题，而且使得扩展设备与原始设备连接的整体感更强，更方便携带，不容易受到碰撞等影响，连接可靠性更好。
附图说明
下面将参照附图描述本发明的具体实施例，其中：
图1示出了本发明的连接器中母头的一种结构示意图；
图2示出了本发明的连接器中公头的一种结构示意图；
图3示出了本发明的连接器中公头与母头扣合时的结构示意图；

具体实施方式
为了使本发明的技术方案及优点更加清楚明白，以下结合附图对本发明的示例性实施例进行进一步详细的说明，显然，所描述的实施例仅是本发明的一部分实施例，而不是所有实施例的穷举。并且在不冲突的情况下，本说明中的实施例及实施例中的特征可以互相结合。
如图1示出了本发明连接器中母头1的一种具体实施例。在该实施例中，母头1主要包括连接器壳体11、连接器19、母头信号端子13、母头电源端子12和母头管脚。其中，连接器19连接在连接器壳体11内，并与连接器壳体11形成一个环形插接腔。另外，连接器19与连接器壳体11两者可通过注塑一体成型。母头信号端子13和母头电源端子12并行设置在连接器壳体11及连接器19的两长边上，并沿连接器19的轴线呈全对称布置。多个母头管脚相互平行地设在壳体11的底部，母头管脚的一端凸出连接器壳体11的侧面，并与母头信号端子13或母头电源端子12一一对应，即每一个母头信号端子13或每一个母头电源端子12分别对应有一个母头管脚。在一个优选的实施例中，母头管脚的轴线垂直于连接器19的轴线设置。
在一个优选的实施例中，连接器19上设有若干金属弹片14，靠近中部的金属弹片14与对应的母头信号端子13对应，靠近两端的金属弹片14与母头电源端子12对应。其中，设置金属弹片14的主要效果在于，母头1与公头2插接配合时，设置了金属弹片14可适应长行程插接配合，而且具有高可靠性。另外，金属弹片14的设置可提高母头1与公头2的可插接配合次数，使得本发明的连接器插接配合寿命最高达到300次或以上。
在一个优选的实施例中，如图1所示，连接器19的两端设有导向槽17，该导向槽17在母头1与公头2插接扣合时起到导向和固定位置的作用。
在一个优选的实施例中，如图1或图4所示，壳体11的底部还设有第一定位结构18，该第一定位结构18可以为定位圆柱。该定位圆柱精确定位 母头1连接到第一焊接基板3上的位置。
如图2示出了本发明连接器中公头2的一种具体实施例。在该实施例中，该公头2主要包括公头壳体21、公头端子和公头管脚25。公头壳体21上设有多组公头端子，公头端子包含有多组公头电源端子22和公头信号端子23。公头壳体21的下表面连接有多个公头管脚25，公头管脚25凸出公头壳体21的侧面并与公头端子一一对应。由于公头端子并联设置在公头壳体21的两长边上，公头管脚25外伸的一端凸出对应长边的外侧面。
在一个优选的实施例中，如图2或图4所示，公头壳体21的一端内侧设有凸块24，该凸块24在公头2与母头1插接配合时与连接器19其中的一个导向槽17配合，起到导向和固定相对位置的作用。公头壳体21的另一端靠近公头管脚25的一面(图2中底面，图4中为上表面)连接有第二定位结构26。在进一步优选的实施例中，第二定位结构26为两个定位圆柱，这两个定位圆柱精确定位公头2连接到第二焊接基板4上的位置。
在一个实施例中，公头信号端子23设在公头壳体21的中部，公头电源端子22对称分布在公头信号端子23的两侧。在一个未示出的实施例中，也可以将公头电源端子22设在公头壳体21的中部，公头信号端子23分布在公头电源端子22的两侧。
在一个优选的实施例中，公头壳体21采用防火塑料制成，多组公头端子通过一次压制方式连接到公头壳体21上。
在一个实施例中，如图3所示，示出了公头2与母头插接扣合的结构。其中，公头2的公头壳体21插接到连接器壳体11与连接器19之间的环形插接腔内。公头管脚25压接在母头1的公头管脚25上，位于同侧的公头电源端子22及公头信号端子23分别与对应母头1的母头电源端子12及母头信号端子13形成连接，在通电或信号传输中形成传输通道。
可以理解的是，参考图3，由于母头1与公头2是配合的结构，公头信 号端子23设在公头壳体21的中部、公头电源端子22对称分布在公头信号端子23的两侧时，母头1中相应地应是母头信号端子13连接在连接器壳体11的中部，多个母头电源端子12位于母头信号端子13的两侧。若是公头2的结构发生变化，例如，将公头电源端子22设在公头壳体21的中部而公头信号端子23分布在公头电源端子22的两侧，母头1的结构相应地发生变化。反过来，如果母头1的结构发生变化，公头2的结构也应发生相应的变化。
在一个优选的实施例中，本发明的连接器可采用加宽加厚的端子作为电源端子(此处的电源端子对应本发明中的母头电源端子12和公头电源端子22)。例如，母头信号端子13的宽度是0.17mm，母头电源端子12采用宽度为1mm的端子。经试验测试，单个电源端子最大可通过4A电流，而单个信号端子最大可通过电流为0.5A。
另外，由于母头管脚需要与母头端子的尺寸进行匹配，因而，对应母头电源端子12设置有加宽加厚母头管脚15，对应母头信号端子13设置有普通母头管脚16，如图1所示。相应地，公头电源端子22采用加宽加厚的端子，公头管脚25采用加宽加厚的管脚。
在一个实施例中，采用加宽加厚的端子作为电源端子时，若连接器为采用6组专用加宽加厚电源端子组成的结构，单组电源端子最大可支持4A的电流，6组电源端子可支持24A的电流传输，因而可实现大功率器件大电流和信号的同时传输。通过加宽加厚电源端子，端子数量较少，可避免大功率电流传输引发的过高温升。通过测试，即使6组电源端子同时工作，也可确保连接器温度上升在30摄氏度以内。
在一个实施例中，如图4示出了本发明的连接器的一种分解结构示意图。在该图中，公头2通过其上面的第二定位结构26与第二焊接基板4上的定位孔的配合形成准确定位连接，母头1通过其底面的第一定位结构18 与第一焊接基板3上的定位孔配合形成准确定位连接。另外，该图还简单示出了导出模块5，通过该导出模块5可以实现另一端的连接。例如，在图5所示的实施例中，将本发明的连接器设在移动设备6的背面，可通过导出模块5转接，以叠加的方式连接到扩展设备，方便模组间的可靠连接。常用的连接形式有：背连小型扩展设备；嵌入大型扩展设备时，一般需要通过专用数据线和适配器来进行连接。同时，背接、嵌入等方式可提供稳定的固定方式，增强了原始设备与扩展设备连接的整体感，使原始设备和扩展设备结合成一个新的设备。说明的是，在图5中，公头2位于第二焊接基板4的背面。
此外，本发明的连接器本身支持同时进行多功能连接，包括电源、USB信号和高速数据，不仅丰富了扩展设备的功能，为单一扩展设备提供多种功能支持，而且为原始设备平台和扩展设备的结合提供了更多的组合方式。再加上本发明的连接器在设计上保证了多次插拔使用的寿命，可以在同一原始设备上更换不同的扩展设备，达到经济性，灵活性和可靠性的统一。同时，本发明将电源端子和信号端子共同设在一个连接器内，也能节省空间，增加连接的可靠性。
尽管已描述了本发明的优选实施例，但本领域内的技术人员一旦得知了基本创造性概念，则可对这些实施例作出另外的变更和修改。所以，所附权利要求意欲解释为包括优选实施例以及落入本发明范围的所有变更和修改。另外可以理解的是，只要不存在结构上的冲突，各实施例中的特征均可相互结合起来，所形成的组合式特征仍属于本发明的范围内。本发明并不局限于文中公开的特定实施例，而是包括落入权利要求的范围内的所有技术方案。
