背景技术
图1是典型的PCB单连接器或多连接器的剖视图。在PCB单连接器或多连接器中，阳连接器112插入并连接到安装在PCB 160上的阴连接器(或插座)150，所述阳连接器112包括阳连接器壳体112，阳连接器壳体112覆盖用于传输电信号的电信号线114例如缆线或电线的端子。在此，阴连接器150的阴连接器壳体152设置有用于接纳阳连接器中的端子(或引脚)接纳构件154。
然而，这种典型的PCB单连接器或多连接器具有以下问题：很可能会通过接纳构件154发生电流泄漏，从而导致信号损失，并且对连接器的小型化存在限制。
发明内容
已经构思了本发明的实施方式来解决典型的PCB单连接器或多连接器的问题，并且本发明的一方面是提供一种用于传输超高频信号的紧凑型连接器，紧凑型连接器包括：阴连接器，阴连接器仅包括壳体插座，壳体插座安装在PCB上并且用于接纳阳连接器壳体，而没有用于接纳阳连接器中的单根或多根超高频信号线的端子的单独的端子接纳构件，使得阳连接器中的端子可以与PCB上的端子焊盘直接接触，从而通过最大程度地减小连接器的高度，而使信号损失最小化并且实现小型化。
根据本发明的一个方面，提供了一种用于传输超高频信号的紧凑型连接器，该紧凑型连接器适于将印刷电路板(PCB)连接至单根或多根超高频信号线，所述超高频信号线对通过所述超高频信号线的超高频信号进行传输，紧凑型连接器包括：阳连接器，该阳连接器连接至单根或多根超高频信号线，并且该阳连接器包括阳连接器壳体，阳连接器壳体接纳、固定并且保护所述单根或多根超高频信号线的端子；以及连接器插座，所述连接器插座安装在所述PCB上并且接纳要被紧固至阳连接器的阳连接器壳体，其中，阳连接器中的超高频信号线的端子分别与形成在所述印刷电路板上的信号线端子焊盘直接接触、并且分别连接至形成在所述印刷电路板上的信号线端子焊盘。
阳连接器壳体可以是连接到屏蔽层的屏蔽罩件，该屏蔽层阻挡由单根或多根超高频信号线产生的电磁波；以及连接器插座可以接纳屏蔽罩件，并且连接器插座可以电连接到屏蔽罩件和PCB的接地端子。阳连接器可以进一步包括适配器，该适配器允许超高频信号线分别与形成在PCB上的信号线端子焊盘接触，并且所述适配器在所述适配器的一个端部处连接至超高频信号线，而在所述适配器的另一个端部处连接到PCB上的电路信号线端子焊盘，并且超高频信号线可以通过阳连接器的适配器连接到印刷电路板上的电路信号线端子焊盘。
屏蔽罩件可包括适配器接纳部分，该适配器接纳部分接纳一对一地连接至单个或多个同轴缆线的内部导体的单个或多个适配器，该适配器接纳部分构造成单独地屏蔽适配器。连接器插座可以进一步包括要被紧固到阳连接器的紧固部分。连接器插座可以通过如下技术安装在PCB上：表面安装技术(SMT)；通孔安装技术，例如单列直插式封装(SIP)技术、双列直插式封装(DIP)技术和四列直插式封装(QIP)技术；或表面安装技术与通孔安装技术的组合。
在根据本发明的用于传输超高频信号的紧凑型连接器中，省略了通常设置在连接器插座上以接纳阳连接器中的信号线端子的接纳构件，使得阳连接器中的信号线端子可与PCB上的信号线端子焊盘直接接触，或者提供适于接纳缆线内部导体的端部的适配器，以使阳连接器中的信号线端子与PCB上相应的信号线端子焊盘之间易于接触，从而最小化电流泄漏和噪声，以减少信号损失，同时允许通过减小连接器的紧固高度来使连接器最小化。
另外，根据本发明，当信号线是同轴缆线时，作为连接到阳连接器的同轴缆线的屏蔽层的外部导体连接到屏蔽罩件，阻挡由作为同轴缆线的信号线的内部导体产生的电磁波，通过接纳屏蔽罩件，使安装在PCB上并连接至PCB的接地端子的连接器插座与阳连接器的屏蔽罩件接触、并且使安装在PCB上并连接至PCB的接地端子的连接器插座电连接至阳连接器的屏蔽罩件，从而减少阳连接器中的信号线端子中的信号损耗，阳连接器中的信号线端子直接接触PCB上的电路信号端子焊盘。
此外，根据本发明，由于可以省去用于将阳连接器中的信号线端子接纳在连接器插座的单独的接纳构件，因此可以简化连接器插座的结构，从而可以减少制造成本。

图2是根据本发明的用于传输超高频信号的紧凑型连接器的示例的视图，其中阳连接器20未被紧固至安装在PCB 215上的连接器插座225。图3是根据本发明的PCB多连接器的视图，其中阳连接器20被紧固至安装在PCB 215上的连接器插座225。参照图2和图3，将与缆线240连接的阳连接器的壳体270、280、290插入并紧固至安装在PCB 215上的连接器插座225中。这里，通过使形成在阳连接器的底表面上的缆线端子分别与形成在PCB 215上的电路信号线端子焊盘直接接触，来建立PCB与缆线240之间的连接。
图4是根据本发明的用于传输超高频信号的紧凑型连接器的阳连接器20和连接器插座225的底部透视图。图5是根据本发明的用于传输超高频信号的紧凑型连接器的分解透视图，示出了连接器插座225和PCB 215。参照图4和图5，缆线信号线端子255形成在阳连接器20的底表面上。连接器插座225可以包括要被紧固至阳连接器20的紧固部分222。连接器插座225可以通过如下技术安装在PCB 215上：表面安装技术(SMT)；通孔安装技术，例如单列直插式封装(SIP)技术、双列直插式封装(DIP)技术和四列直插式封装(QIP)技术；或表面安装技术与通孔安装技术的组合。可替代地，连接器插座225可以与PCB一体地形成，而不是与PCB分开地形成。
当阳连接器20的壳体270、280、290插入并紧固至安装在PCB 215上的连接器插座225上时，缆线信号线端子255分别与在PCB 215上形成的电路信号线端子焊盘214直接接触，而无需使用单独的用于接纳缆线信号线端子255的接纳构件。根据本发明，由于安装在PCB 215上的连接器插座225没有设置用于接纳缆线信号线端子255的接纳构件，如图4所示，因此可以简化连接器插座的结构，并且可以最小化将连接器插座紧固至阳连接器的高度，从而可以使连接器小型化。根据本发明的用于传输超高频信号的紧凑型连接器可以将用于传输诸如RF信号和电源信号之类的电信号的信号线连接至PCB或电源，并且根据本发明的用于传输超高频信号的紧凑型连接器可以被应用于需要相关连接器小型化的各种电子装置，例如平板电脑、笔记本电脑、5G智能手机和家用电器(例如电视、冰箱、洗衣机等)。
根据本发明的经由用于传输超高频信号的紧凑型连接器连接的用于传输超高频信号的单根或多根超高频信号线的示例可以包括同轴缆线、电线、柔性扁平缆线(FFC)、柔性印刷电路(FPC)、S-Teflon等。然而，将理解，本发明不限于此，并且超高频信号线可以包括适于通过其传输电信号的任何信号线。图6是作为示例性电信号线的同轴缆线30的视图，所述同轴缆线30连接到根据本发明的用于传输超高频信号的紧凑型连接器的阳连接器20。参照图6，同轴缆线30中的每者都包括：用作信号线的内部导体210，由铝、铜等形成并阻挡由内部导体210产生的电磁波的外部导体230，使内部导体210与外部导体230绝缘和隔离的电介质220，以及保护外部导体230的护套(或外壳)。内部导体可以传输各种电信号，例如DC信号、微波信号和毫米波信号，尤其是大约50GHz或更高的超高频信号。
图7是构成根据本发明的用于传输超高频信号的紧凑型连接器的阳连接器20的示例性部件的视图。根据本发明的用于传输超高频信号的紧凑型连接器的阳连接器20包括同轴缆线30和屏蔽罩件270、280、290，并且根据本发明的用于传输超高频信号的紧凑型连接器的阳连接器20还可以包括适配器单元40。护套240、外部导体230、以及同轴缆线30的电介质220被部分地剥离。同轴缆线30的外部导体230可以连接到屏蔽罩件270、280、290。屏蔽罩件270、280、290接纳、保护并固定同轴缆线30，并且屏蔽罩件270、280、290阻挡由同轴缆线的内部导体210产生的电磁波。屏蔽罩件270、280、290可通过将下屏蔽构件270、上屏蔽构件280和前屏蔽构件290彼此联接而形成。然而，应当理解，本发明不限于此，下屏蔽构件270、上屏蔽构件280和前屏蔽构件290中的至少两者可以彼此一体地形成，或者屏蔽罩件可以由一个屏蔽构件构成，在该屏蔽构件中，下屏蔽构件270、上屏蔽构件280和前屏蔽构件290彼此一体地形成。
适配器单元40包括多个适配器。每个适配器42被配置为容易被屏蔽罩件270、280、290屏蔽，并且每个适配器42被配置为允许在同轴缆线30的内部导体210与形成在PCB 215上的电路信号线端子焊盘214之间的容易的连接，并且每个适配器42包括导体部分250和电介质部分260。导体部分250的一个端部与PCB 215上的信号线端子焊盘214接触并且连接至PCB 215上的信号线端子焊盘214，导体部分250的另一个端部接纳信号线210即同轴缆线30的内部导体、并连接至信号线210即同轴缆线30的内部导体。当内部导体即缆线的信号线被接纳在适配器42中并连接至适配器42时，导体部分250的与图4的缆线信号线端子255相对应的一个端部与PCB215上的信号线端子焊盘214接触并连接至PCB 215上的信号线端子焊盘214。
电介质部分260用于将被接纳在屏蔽罩件270、280、290中的导体部分250与所述屏蔽罩件分开。
屏蔽罩件270、280、290包括形成在其中的适配器接纳部分272，所述适配器接纳部分272具有筒形部分，所述筒形部分适于分别接纳一对一地连接至单根或多根同轴缆线的内部导体210的适配器42。适配器接纳部分272被构造为形成屏蔽壁，所述屏蔽壁适于将被接纳在适配器接纳部分中的适配器彼此分开，并且所述屏蔽壁适于在下屏蔽构件270联接到上屏蔽构件280和前屏蔽构件290时屏蔽适配器。
图8是图2的沿线VII-VII截取的阳连接器的剖视图，以及图9是图2的沿线VIII-VIII截取的阳连接器的剖视图。参照图8和图9，在同轴缆线210、220、230、240和适配器250、260被屏蔽罩件270、280、290接纳、保护和屏蔽的情况下，将阳连接器20插入并紧固至安装在PCB 215上的连接器插座225。特别地，图9示出了通过将下屏蔽构件270、上屏蔽构件280和前屏蔽构件290彼此联接而形成的屏蔽壁275，其中，在屏蔽适配器的同时，这些屏蔽壁将适配器彼此分开。图10是示出根据本发明的用于传输超高频信号的紧凑型多连接器的阳连接器的组装过程的视图。参照图10，剥离未剥离开的同轴缆线60，随后将剥离开的同轴缆线30连接至适配器单元40，然后将连接至适配器单元40的同轴缆线50坐置在下屏蔽构件270上，再将下屏蔽构件270联接到上屏蔽构件280和前屏蔽构件290。
当同轴缆线用作信号线时，根据本发明的用于传输超高频信号的紧凑型连接器可以提供对由信号线产生的电磁波的最大化的屏蔽。具体地，阳连接器20的屏蔽罩件270、280、290连接到同轴缆线30的外部导体230。由导体形成的连接器插座215连接到PCB 215的接地端子。当将阳连接器20插入并紧固至安装在PCB 215上的连接器插座225中时，使连接到同轴缆线30的外部导体230的阳连接器20的屏蔽罩件270、280、290与连接到PCB 215的接地端子的连接器插座225接触、并且使连接到同轴缆线30的外部导体230的阳连接器20的屏蔽罩件270、280、290连接到与PCB 215的接地端子连接的连接器插座225，从而使屏蔽由阳连接器中的信号线端子产生的电磁波的屏蔽效应最大化，所述阳连接器中的信号线端子分别与PCB 215上的端子焊盘214直接接触。
尽管这里已经参考附图描述了一些实施方式，但是本领域技术人员应该理解，这些实施方式仅是通过示例的方式给出的，并且本领域技术人员可以在不脱离本发明的精神和范围的情况下进行各种修改、变化和变更。因此，本发明的范围应仅由所附权利要求及其等同物限制。
