本申请涉及信号连接技术领域，尤其涉及一种将第一连接器和第二连接器相互嵌合而构成的多极连接器。
 背景技术
现今电子科技的快速发展，使得电子设备被广泛应用，电子设备内部会被设置多种不同功能的电路基板，以符合用户对于电子设备的各种功能需求。目前，通常采用多级连接器电连接两块电路基板。
 技术问题
常规多级连接器的单个连接器由内部端子、绝缘部件、外部端子（金属外壳）组成。产品内部无屏蔽部件,从而导致内部端子相互间会产生信号干扰；或者，屏蔽部件是独立镶嵌在绝缘部件内并与外部端子分离，从而在一定程度上影响屏蔽隔离效果，另外，屏蔽部件单独嵌入绝缘部件时难以准确定位。
因此，实有必要提供一种新的多极连接器解决上述技术问题。
 技术解决方案
本申请的目的在于提供一种多极连接器，该多极连接器无需屏蔽部件单独嵌入成形。
为了达到上述目的，本申请提供了一种多极连接器，其是将第一连接器和第二连接器相互嵌合而构成的，所述第一连接器具备排列成多列的内部端子和保持这些内部端子的绝缘部件，所述第二连接器具备排列成多列的内部端子和保持这些内部端子的绝缘部件，所述第一连接器和所述第二连接器中的至少一方还具备外部端子，所述外部端子与接地电位连接并被所述绝缘部件保持，所述外部端子沿所述内部端子的列所延伸的方向延伸形成被所述绝缘部件保持的屏蔽部件，在所述第一连接器和所述第二连接器各自的所述内部端子彼此接触并相互嵌合的状态下，所述屏蔽部件配置于所述内部端子的列间。
优选地，所述屏蔽部件包括第一屏蔽部件和第二屏蔽部件，所述第一屏蔽部件和所述第二屏蔽部件沿所述内部端子的列所延伸的方向对置。
优选地，所述第一屏蔽部件和所述第二屏蔽部件相互接触。
优选地，所述屏蔽部件为一体结构。
优选地，所述外部端子包括第一外部端子和第二外部端子，所述屏蔽部件位于所述第一外部端子和所述第二外部端子之间。
优选地，所述第一外部端子和所述第二外部端子围合形成包围所述内部端子的环状结构。
优选地，所述外部端子呈包围所述内部端子的连续的环状结构。
优选地，所述第一连接器和所述第二连接器中仅所述第一连接器具备所述外部端子和所述屏蔽部件，所述第一连接器的所述绝缘部件上设有环状的凹槽，所述凹槽将所述第一连接器的所述绝缘部件划分为周边部和中心部，所述外部端子被所述周边部保持，所述屏蔽部件被所述中心部保持；

 有益效果
与相关技术相比，本申请的多极连接器通过将屏蔽部件与外部端子集成为一体结构，以避免屏蔽部件单独嵌入绝缘部件导致的屏蔽部件难以准确定位的问题（屏蔽部件单独嵌入绝缘部件时定位不准确会消弱屏蔽部件的屏蔽隔离效果），从而可以提高屏蔽效果。

实施例一
图7所示的多极连接器是图1所示的第一连接器1和图4所示的第二连接器3按照如图6所示那样相互嵌合而构成的。第一连接器1和第二连接器3分别与不同的电路基板（未图示）连接，这些电路基板由第一连接器1和第二连接器3相互嵌合而构成的多极连接器电连接。
如图1、图2及图3所示，第一连接器1具备多个内部端子11、绝缘部件13、外部端子15及屏蔽部件17。
多个内部端子11被设置成多列，每一排列有若干个内部端子11。在图1和图2所示的例子中，多个内部端子11被设置成两列，每一列排列有五个内部端子11。其中，将一列内部端子11的列所排列的方向设为X方向（即X方向为内部端子11的列所延伸的方向）。
多个内部端子11分别是与信号电位或接地电位连接的导体。内部端子11由具有导电性的棒状部件折弯而成。内部端子11被嵌合保持于绝缘部件13的槽中。在图7和图8所示的第一连接器1和第二连接器3相互嵌合状态下，第一连接器1的内部端子11与后述的第二连接器3的内部端子31接触。通过内部端子11与内部端子31接触，从而使第一连接器1和第二连接器3之间电连接。
绝缘部件13是将多个内部端子11、外部端子15及屏蔽部件17一体保持的绝缘性的部件。绝缘部件13可以采用树脂材料制成，当然，绝缘部件13也可以采用其他绝缘性的材料制成。在本实施例中，通过将多个内部端子11、外部端子15及屏蔽部件17嵌件成型于绝缘部件13以制造第一连接器1。
在图1和图2所示的例子中，绝缘部件13上设有环状的凹槽131，凹槽131将绝缘部件13划分为周边部133和中心部135，外部端子15被周边部133保持，屏蔽部件17被中心部135保持。
外部端子15被保持于绝缘部件13并包围多个内部端子11。外部端子15是与接地电位连接的导体。外部端子15与接地电位连接而保持地电位，由此屏蔽来自第一连接器1外部的电磁波，以使第一连接器1内部为电屏蔽空间，从而使多个内部端子11在外部端子15的屏蔽作用下不受来自连接器外部的电磁波干扰。
在图2和图3所示的例子中，外部端子15包括第一外部端子151和第二外部端子153，屏蔽部件17位于第一外部端子151和第二外部端子153之间。第一外部端子151和第二外部端子153被保持于绝缘部件13。如图3所示，第一外部端子151和第二外部端子153围合形成包围多个内部端子11的环状结构，第一外部端子151和第二外部端子153均包括沿X方向设置的长轴边155及自长轴边155的两端延伸形成的第一短轴边157和第二短轴边159，其中，第一短轴边157相对于第二短轴边159更加靠近内部端子11。
屏蔽部件17是由外部端子15沿内部端子11的列所延伸的方向（即X方向）延伸形成并被保持于绝缘部件13。也就是说，屏蔽部件17集成在外部端子15上。屏蔽部件17是用于抑制内部端子11的列间的电磁波干扰的部件。如图1和图8所示，屏蔽部件17被保持于绝缘部件13并位于抑制内部端子11的列间。通过将屏蔽部件17和外部端子15集成为一体，使得屏蔽部件17和外部端子15一起保持一体的地电位，以使得具有地电位的屏蔽部件17构建电磁波的屏蔽，从而抑制内部端子11的列间的电磁波干扰。
在图2和图3所示的例子中，屏蔽部件17包括第一屏蔽部件171和第二屏蔽部件173，第一屏蔽部件171和第二屏蔽部件173沿内部端子11的列所延伸的方向对置（即屏蔽部件17被分成两个部分）。如图3所示，第一屏蔽部件171由第一外部端子151的第一短轴边157沿内部端子11的列所延伸的方向（即X方向）延伸形成，第二屏蔽部件173由第二外部端子153的第一短轴边157沿内部端子11的列所延伸的方向（即X方向）延伸形成。
在图3所示的例子中，第一屏蔽部件171和第二屏蔽部件173相互接触。当然，第一屏蔽部件171和第二屏蔽部件173也可以间隔设置，在间隔设置的情况下，也能够通过第一屏蔽部件171和第二屏蔽部件173接近而构建电磁屏蔽。由此，能够阻断经由第一屏蔽部件171和第二屏蔽部件173之间的空间而产生的电磁耦合，从而能够抑制内部端子11的列间的电磁波干扰。
如图4和图5所示，第二连接器3具备多个内部端子31和绝缘部件33。
内部端子31是与前述的第一连接器1的内部端子11接触的导体，并被保持于绝缘部件33。内部端子31由具有导电性的棒状部件折弯而成。
每一个内部端子31与第一连接器1的每一个内部端子11一一对应设置。更具体的是，多个内部端子31也被设置成两列，每一列排列有五个内部端子31，每一个内部端子31与每一个内部端子11一一对应地接触。
绝缘部件33是将多个内部端子31保持的绝缘性的部件。绝缘部件33也可以采用树脂制成，当然，绝缘部件33也可以采用其他绝缘性的材料制成。
绝缘部件33上设有容纳槽331。在图8所示的第一连接器1和第二连接器3各自的内部端子彼此接触并相互嵌合的状态下，第一连接器1的绝缘部件13的中心部135收容于容纳槽331内，容纳槽331的侧壁插入绝缘部件13上的凹槽131内。通过凹槽131和容纳槽331的设置，使得在第一连接器1和第二连接器3各自的内部端子彼此接触并相互嵌合的状态下：
第一连接器1的外部端子15除包围前述的第一连接器1的多个内部端子11外，还包围第二连接器3的多个内部端子31，以使多个内部端子31在第一连接器1的外部端子15的屏蔽作用下不受来自连接器外部的电磁波干扰；以及，
屏蔽部件17还用于抑制内部端子31的列间的电磁波干扰，如图8所示，屏蔽部件17还位于抑制内部端子31的列间。在多极连接器中，特别是内部端子11、31传输有高频信号的情况下，在内部端子11、31的列间容易产生电磁波的干扰，通过在内部端子11、31的列间设置屏蔽部件17而构成电磁波的屏蔽，从而能抑制内部端子11、31的列间容易产生电磁波的干扰，特别是能提高高频用途中的多极连接器的信号传输性能。
图8中示出了第一连接器的内部端子11和第二连接器的内部端子31彼此接触并相互嵌合的状态。
如图8所示，第一连接器1的内部端子11在其靠近第一连接器1的屏蔽部件17的端部具有背离第二连接器的内部端子31侧凹陷的凹形状111。与此相对应的是，第二连接器的内部端子31在其靠近第一连接器1的屏蔽部件17的端部具有与内部端子11的凹形状111对应的凸形状311。
在图8所示的嵌合状态下，内部端子31的凸形状311插入内部端子11的凹形状111并彼此接触。第一连接器1的内部端子11或/和第二连接器的内部端子31由可弹性形变材料（例如，磷青铜）制成，若内部端子31的凸形状311插入内部端子11的凹形状111，则凹形状111向外扩张（即内部端子11由可弹性形变材料制成）或/和凸形状311向内收缩（即内部端子31由可弹性形变材料制成），由于凹形状111或/和凸形状311欲恢复原来的初始形状（即未插入时，凹形状111或/和凸形状311的形状），所以凹形状111和凸形状311之间会存在使凸形状311夹紧在凹形状111内的作用力。通过这种作用力的作用，从而使得第一连接器1的内部端子11和第二连接器3的内部端子31嵌合。
