Description

一种具有接触元件的射频同轴电连接器 技术领域
本发明涉及射频同轴连接器，尤其涉及一种具有接触元件的射频同轴电连接器，以及射频同轴电连接器的无源互调、阻抗匹配以及密封。
背景技术
ZL200810068882.X和ZL03103882.4公开了提高射频同轴连接器的无源互调性能的技术方案。
在ZL200810068882.X中，两个连接单元的外导体之间没有接触元件，而是通过增加一个辅助螺母和弹性垫圈保证两个外导体的接触面紧密贴合，以提高两个单元连接的无源互调性能。
在ZL03103882.4中，连接器两个连接单元的外导体之间设置一个环形圆盘状具有弹性的接触元件，两个外导体均和接触元件的封闭圆周循环线紧密接触，以提高连接器的无源互调性能。
上述专利技术为了提高连接器的无源互调性能，分别采用不同的结构实现插头外导体和插座外导体之间紧密而稳定地连接，以此提高射频同轴连接器的无源互调性能。
与本发明密切相关、申请在先公开在后的WO2013/104590A1，公开了一种射频同轴电连接器，其弹性接触部(spring loaded contact elements) 26与插头外导体为一体加工成型的，导致插头外导体的结构和形状复杂，不便于零件的模块化成型与使用，而且，其弹性接触部26的材质必须与插头外导体的材质相同，不便于选择性地将弹性接触部26和弹性接触部26以外的插头外导体分别使用不同的材料从而在确保一定弹性电接触性能的基础上降低产品制造成本。
发明内容
本发明的目的是提供一种射频同轴电连接器，涉及连接器的插头和插座，插头和插座两者之一具有独立成型的接触元件，以提高插头和插座的插合后的无源互调性能或三阶互调性能。
本发明的另外一个目的是提供一种具有接触元件的射频同轴电连接器，其可减小连接器长度方向需要占用的空间，提高射频同轴连接器的阻抗匹配性能，减小射频同轴连接器的驻波比。
本发明的另外一个目的是提供一种具有快锁装置的射频同轴电连接器，其可提高射频同轴连接器的密封性能，防止连接外部的气态、液态的物质或尘埃进入连接器内部，影响连接器的电气性能。
为此，根据本发明的第一方面，提供了一种具有接触元件的射频同轴电连接器，包括插头(1)和插座(2)，插头(1)包括插头外导体(11)、插头绝缘体(13)、和插头内导体(17)，而插座(3)包括插座外导体(22)、插座介质体(23)、插座内导体(24)，其特征在于：在插头外导体(11)和插座外导体(22)之间设有接触元件(14)，该接触元件(14)呈圆筒状，其前部通过各轴向的剖槽(142)分割为多个弹性的悬臂梁，其后部为圆环状的接触环(143)；接触元件(14)的悬臂梁从接触环(143)轴向伸出，悬臂梁的前端设置有径向向外凸起的环状触点(141)；接触元件(14)通过后部的接触环(143)过盈配合固定在插头外导体(11)内设置的插头第一台阶孔(113)中，通过前部弹性的悬臂梁的环状触点(141)伸入插座外导体(22)内设置的插座第一台阶孔(221)内与其侧壁紧密弹性接触。
优选地，接触元件(14)由有弹性的铜合金制成。
优选地，环状触点(141)与插座第一台阶孔(221)内侧壁接触为环状的线接触或面接触。
优选地，在插头第一台阶孔(113)后设置有插头第二台阶孔(114)，在插头第一台阶孔(113)前相继设置有插头第三台阶孔(112)和插头第四台阶孔(111)；插头第四台阶孔(111)的外径大于插头第三台阶孔(112)的外径，插头第三台阶孔(112)的外径大于插头第一台阶孔(113)的外径，第一台阶孔(113)的外径大于插头第二台阶孔(114)的外径；插头第二台阶孔(114)容纳并固定插头绝缘体(13)。
根据本发明的第二方面，提供了一种射频同轴电连接器，进一步地，其所述的插头绝缘体(13)至少部分地容纳于接触元件(14)内，在插头绝缘体(13)的两端之间的插头内导体(17)上，设置环形的内导体槽(171)。
优选地，所述的内导体槽(171)所包围的插头内导体(17)的一部分设置为中间大，两头小的结构。
根据本发明的第三方面，提供了一种射频同轴电连接器，进一步地，其设置有一个密封帽(3)，其通过螺纹连接固定在插座外导体(22)上，密封帽(3)为管状，在插座外导体(22)上设置插座密封槽(224)，插座密封槽(224)内置第二密封圈(5)，在插头外导体(11)上设置插头密封槽(112)，插头密封槽(119)内置第三密封圈 (4)；当所述的插头(1)与插座(2)插合后，密封帽(3)两头的内壁分别挤压第二密封圈(5)和第三密封圈(4)，实现连接器的密封。
与现有技术ZL 200820096613.X相比，通过设置密封帽(3)、插座密封槽(224)、插头密封槽(112)，并在插座密封槽(224)内置第二密封圈(5)，插头密封槽(119)内置第三密封圈(4)，为密封连接器起到了作用。
根据本发明，采用了与现有技术完全不同的结构，可以提高射频同轴连接器的无源互调性能或三阶互调性能。而且，根据本发明进一步详细的技术方案，可以提高射频同轴连接器的阻抗匹配性能，可减小连接器长度方向需要占用的空间，减小射频同轴连接器的驻波比甚至于可以提高连接器的密封性能。
与现有技术ZL 03103882.4相比，环状触点(141)与插座外导体内的插座第一台阶孔(221)的侧壁在连接器的径向紧密弹性接触，当环状触点(141)的电接触部位如图2和图5所示在经过接触元件(14)的中心轴线的剖面的轮廓为弧状时，所述的紧密弹性接触为环状的线接触，因此可以大幅度提高射频同轴连接器的无源互调性能或三阶互调性能，当环状触点(141)的电接触部位如图4在经过接触元件 (14)的中心轴线的剖面的轮廓为线段时，所述的紧密弹性接触为环状的面接触，因此可以提高射频同轴连接器的传输大功率特性。
相对于根据本发明的一个实施例，插头绝缘体(13)位于接触元件(14)的后面，根据本发明进一步详细的技术方案，由于插头绝缘体(13)至少部分地容纳于接触元件(14)内，固定插头内导体(17)的插头绝缘体(13)可以往前移，减小了连接器长度方向所需要占用的空间。同时，在插头绝缘体(13)的两端之间的插头内导体(17)上，设置环形的内导体槽(171)，有助于补偿阻抗匹配，减小射频同轴连接器的驻波比。优选地，将内导体槽(171)所包围的插头内导体(17)的一部分设置为中间大，两头小的结构，更有助于阻抗匹配性能的提高，减小射频同轴连接器的驻波比。
与WO2013/104590A1相比，本发明的接触元件是一个独立的零件，与插头内导体通过过盈配合连接成一体。因此，在本发明中，接触元件和插头内导体的结构和形状都比较简单，接触元件和插头内导体可以分别制造，尤其是接触元件可以模块化成型与使用，有利于选择性地将接触元件和插头外导体分别使用不同的材料，从而在确保一定弹性电接触性能的基础上降低产品制造成本。

具体实施方式
以下结合附图1-6所示的实施例对本发明的一种具有接触元件的射频同轴电连接器做进一步的详细说明。
对于射频同轴电连接器，在现有技术中有各式各样结构的快锁连接装置，以实现射频同轴连接器的插头和插座的快速连接锁紧和快速分离，如中国专利 ZL03103882.4中所披露的快锁连接方式。类似这样的快锁连接方式，当插头与插座插合锁紧后，不能确保插头外导体和插座外导体之间直接紧密接触，因此，应用这样的快锁连接方式的射频同轴连接器，不能确保其具有良好的无源互调性能或三阶互调性能。
如图1所示，根据本发明的一种具有接触元件的射频同轴电连接器实施例的插头和插座对接结构，所述的射频同轴电连接器同样设置有上述类似的快锁装置。为了解决上述问题，确保两个外导体之间接触良好，提高射频同轴电连接器的无源互调性能，本发明采取与中国专利ZL03103882.4相同的技术构思，在插头外导体和插座外导体之间增设一个弹性的接触元件。
如图2所示，根据本发明的一种具有接触元件的射频同轴电连接器实施例的接触元件14呈圆筒状，其前部通过轴向的剖槽142分割为多个弹性的悬臂梁，其后部为圆环状的接触环143。接触元件14的悬臂梁从接触环143轴向伸出，悬臂梁的前端设置有径向向外的凸起的环状触点141。
如图1所示，接触元件14沿轴向设置在插头外导体11和插座外导体22之间，接触元件14通过后部的接触环143过盈配合固定在插头外导体11内设置的插头第一台阶孔113中，通过前部弹性的悬臂梁的环状触点141伸入插座外导体22内设置的插座第一台阶孔221内与其侧壁紧密弹性接触。接触元件14由有弹性的金属制成，例如一种合适的铜合金。
如图3所示，根据本发明的一种具有接触元件的射频同轴电连接器实施例的插座3包括插座外导体22、插座介质体23、插座内导体24等组成零件。如图4所示，根据本发明的一种具有接触元件的射频同轴电连接器实施例的插头1包括插头外导体11、插头绝缘体13、插头内导体17等组成零件。在该实施例中，插头外导体11内除了设置以上所述的插头第一台阶孔113外，在插头第一台阶孔113后设置有插头第二台阶孔114，在插头第一台阶孔113前相继设置有插头第三台阶孔112、插头第四台阶孔111。插头第四台阶孔111的外径大于插头第三台阶孔 112的外径，插头第三台阶孔112的外径大于插头第一台阶孔113的外径，第一台阶孔113的外径大于插头第二台阶孔114的外径。插头第一台阶孔113用于固定接触元件14，并确保接触元件14与插头外导体11之间紧密而稳定的电接触，插头第二台阶孔114用于容纳并固定插头绝缘体13，插头第三台阶孔112用于过盈配合组装时穿过接触元件14的接触环143，插头第四台阶孔111用于接收插座外导体 22的一部分。
进一步地，为了减小连接器长度方向需要占用的空间，提高射频同轴连接器的阻抗匹配性能，减小射频同轴连接器的驻波比，如图5所示，根据本发明的一种具有接触元件的射频同轴电连接器实施例的插头另一结构，插头绝缘体13至少部分地容纳于接触元件14内，而不是如图4所示的位于接触元件14的后面。同时，在插头绝缘体13的两端之间的插头内导体17上，设置环形的内导体槽171。更进一步地，所述的内导体槽171所包围的插头内导体17的一部分设置为中间大，两头小的结构，可以更好地有助于提高射频同轴连接器的阻抗匹配性能。
为了提高射频同轴连接器的密封性能，防止连接外部的气态、液态的物质或尘埃进入连接器内部，影响连接器的电气性能，如图6所示，根据本发明一种具有接触元件的射频同轴连接的密封结构，设置了一个密封帽3，其通过螺纹连接固定在插座外导体22上，密封帽3为管状，在插座外导体22上设置插座密封槽224，插座密封槽224内置第二密封圈5，在插头外导体11上设置插头密封槽119，插头密封槽119内置第三密封圈4。当上述的插头1与插座2插合后，密封帽3两头的内壁分别挤压第二密封圈5和第三密封圈4，实现连接器的密封。
