以下各实施例的说明是参考附加的图式，用以例示本发明可用以实施的特定实施例。本发明所提到的方向用语，例如「上」、「下」、「前」、「后」、「左」、「右」、「内」、「外」、「侧面」等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本发明，而非用以限制本发明。
本发明实施例提供的印刷电路板的连接结构，采用两片印刷电路板（PCB）对接的方式，其中一片PCB（又可称作第一PCB）的一端开设有收纳部，另一片PCB（又可称作第二PCB）的一端设置有与该收纳部对应的突出部。该突出部与收纳部在两片PCB连接时可以对接、配合，以实现两片PCB之间的物理连接。此外，两片PCB中的其中之一（如第一PCB）的一端设置有露铜区，另一片PCB（如第二PCB）的一端设置有导电弹片，露铜区和导电弹片在两片PCB连接时可以弹性接触，以实现两片PCB之间的电性连接。
如图1所示，为本发明提供的印刷电路板的连接结构的第一较佳实施例的示意图。在本实施例中，在第一PCB11上设置有收纳部，其形状为凹槽，在第二PCB12上设置有突出部，其形状为凸起。详细来讲，在图1中，于第一PCB11的一端开设有凹槽111，该凹槽111被用作收纳部，该凹槽111开设于该第一PCB11一端的中间部位。在该第一PCB11开设有凹槽111的一端，并位于该凹槽111的两侧设置有露铜区112，该露铜区112露铜的一面向上，该露铜区112连通第一PCB11上的电路。在第二PCB12的一端设置有凸起121，该凸起121就是突出部，该凸起121设置于该第二PCB12一端的中间部位，其形状与第一PCB11上的凹槽111对应，亦即该凸起121的形状与该凹槽111的形状互补。在该第二PCB12设置有凸起121的一端，并位于该凸起121的两侧设置有导电弹片122，该导电弹片122连通第二PCB12上的电路。
当第一PCB11与第二PCB12连接时，第一PCB11与第二PCB12对接，第一PCB11上的凹槽111与第二PCB12上的凸起121配合，凸起121卡进凹槽111中，从而实现第一PCB11与第二PCB12的物理连接。此外，除了第一PCB11上的凹槽111与第二PCB12上的凸起121配合之外，第一PCB11上的露铜区112还与第二PCB12上的导电弹片122配合，露铜区112与导电弹片122实现弹性接触。因为露铜区112连通第一PCB11上的电路，导电弹片122连通第二PCB12上的电路，当导电弹片122与露铜区112弹性连接时，第一PCB11与第二PCB12就可以实现电性连接。
如图2所示，为本发明提供的印刷电路板的连接结构的第二较佳实施例的结构图。在本实施例中，第一PCB21上设置有收纳部，其形状为凹槽，第二PCB22上设置有突出部，其形状为凸起。详细地讲，在图2中，第一PCB21的一端开设有凹槽211和凹槽212，这两个凹槽211、212都被用作收纳部。在具体实施本发明提供的技术方案时，充当收纳部的凹槽的数量也可以大于两个，亦即凹槽的数量是根据实际需要而决定的。在图2所示的第二较佳实施例中，凹槽211和凹槽212开设于该第一PCB21一端，两个凹槽211、212之间有间隔。在该第一PCB21开设有凹槽211和凹槽212的一端，并在未开设有凹槽211、212的部位设置有露铜区213和露铜区214，且露铜区213和露铜区214露铜的一面向上，该露铜区213和露铜区214连通第一PCB21上的电路。
在第二PCB22的一端设置有凸起221和凸起222，凸起221和凸起222设置于第二PCB22的一端，凸起221的形状与凹槽211的形状对应，凸起222的形状与凹槽212的形状对应。换句话讲，凸起221、222的形状分别与凹槽211、212的形状互补。在该第二PCB22设置有凸起221和凸起222的一端，并在未设置凸起221和凸起222的部位设置有导电弹片223和导电弹片224，该导电弹片223和导电弹片224连通第二PCB22上的电路。
当第一PCB21与第二PCB22连接时，第一PCB21与第二PCB22对接，第一PCB21上的凹槽211与第二PCB22上的凸起221配合，凸起221卡进凹槽211中，第一PCB21上的凹槽212与第二PCB22上的凸起222配合，凸起222卡进凹槽212中，从而实现第一PCB21与第二PCB22的物理连接。此外，除了第一PCB21上的凹槽211、212与第二PCB22上的凸起221、222配合之外，第一PCB21上的露铜区213还与第二PCB22上的导电弹片223配合，使得露铜区213与导电弹片223实现弹性接触，并且第一PCB21上的露铜区214还与第二PCB22上的导电弹片224配合，使得露铜区214与导电弹片224实现弹性接触。由于该露铜区213和露铜区214连通第一PCB21上的电路，而该导电弹片223和导电弹片224连通第二PCB22上的电路。因此，当导电弹片223与露铜区213弹性连接，导电弹片224与露铜区214弹性连接时，第一PCB21与第二PCB22可以实现电性连接。
在具体实施本发明的技术方案时，上述第一较佳实施例和第二较佳实施例中的收纳部也可以是孔，孔的截面可以是圆形、方形、三角形或者其他形状，而突出部的形状则需与收纳部的形状对应，例如突出部可以是柱体，其截面可以是圆形、方形或者其他形状。当两片PCB连接时，两片PCB对接，第一PCB上的孔与第二PCB上的柱体配合，柱体插进孔中，从而实现第一PCB与第二PCB的物理连接。
同理，第一PCB与第二PCB之间的电性连接方式与第一较佳实施例和第二较佳实施例中的电性连接方式相同，也是通过露铜区与导电弹片的弹性连接而实现电性连接。
如图3所示，为本发明提供的印刷电路板的连接方法的较佳实施例的流程图。为能清楚表述本发明印刷电路板的连接方法，在本实施例中，将结合图1中的印刷电路板的连接结构及其元件的参考标号对图3所示的印刷电路板的连接方法做详细说明。本发明印刷电路板的连接方法提供了第一PCB11及第二PCB12，其中第一PCB11的一端设置有收纳部（即凹槽111），第二PCB12的一端设置有与该收纳部对应的突出部(即凸起121)。在第一PCB11中设置有收纳部的一端设置有露铜区112，在第二PCB12设置有突出部的一端设置有导电弹片122。
详细地，本实施例的印刷电路板的连接方法包括如下的步骤：
S301.将第一PCB11固定在待组装产品的一目标位置上；
S302.将第二PCB12与第一PCB11对接，将第二PCB12一端的突出部插入第一PCB11一端的收纳部，进行对接，实现第一PCB11与第二PCB12的物理连接；
S303.第二PCB12一端的导电弹片122与第一PCB11上的露铜区112弹性接触，实现第一PCB11与第二PCB12的电性连接；
S304.将第二PCB12固定于该待组装产品的另一目标位置。
其中，步骤S301中，可以通过机械方式将第一PCB11固定在待组装产品的目标位置，如螺丝、粘贴或其他方式；步骤S304中，也可以通过机械方式将第二PCB12固定在待组装产品的目标位置，如螺丝、粘贴或其他方式。
在其它实施例中，露铜区和导电弹片的设置，并不局限于上述图1和图2实施例中例举的方式，也可以是在设置有突出部的第二PCB上设置露铜区，对应地在设置有收纳部的第一PCB上设置导电弹片，同样可以实现两个PCB之间的电性连接。
如上所述，在连接两片或者多片PCB时，采用本发明的印刷电路板的连接结构和连接方法，不但可以通过设置在PCB上的突出部和收纳部的配合实现物理连接，同时通过设置在PCB上的露铜区和导电弹片的配合实现电性连接。相较于现有的PCB连接方式，本发明的印刷电路板的连接结构和连接方法可以省去板端连接器、线段连接器以及连接线等连接零部件，从而降低产品成本。此外，通过本发明方案连接的PCB，组装和拆卸都很方便，可以简化操作。
综上所述，虽然本发明已以较佳实施例揭露如上，但上述较佳实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准
