为便于理解， 下面结合附图和具体实施例对本发明作进一步说明。
实施例一
本实施例一提供一种射频连接器， 用于无线通信产品中对共面电路板进 行连接， 如图 1、 2所示， 该射频连接器包括： 第一中心导体、 第一外导体和 第一绝缘体， 其中， 第一中心导体设置在第一外导体中， 第一绝缘体设置在 第一中心导体与第一外导体之间， 第一中心导体为刚性柱体， 柱体一端为接 触部， 接触部前端为锥台体结构或锥体结构。
上述射频连接器中， 第一中心导体为 "L" 形的刚性圓柱体， 第一中心导 体一端的接触部设置在第一外导体外。
实施例二
本实施例提供另一种结构的射频连接器， 该射频连接器也用于无线通信 产品中对共面电路板进行连接， 它可与实施例一中给出的射频连接器配套使 用， 如图 1、 2所示， 该射频连接器包括：
第二中心导体、 第二外导体和第二绝缘体， 第二中心导体设置在第二外 导体中， 第二绝缘体设置在第二中心导体与第二外导体之间， 第二中心导体 由一柱体和该柱体上设置的具有多边形开口的弹性结构体构成。
上述射频连接器中， 第二中心导体的弹性结构体的开口可以设为 V字型结 构或类似的外张式开口结构， 这样可以方便第一射频连接器与第二射频连接 器连接时， 第一中心导体的接触部在第二中心导体的开口多边型弹性结构体 上的插拔。
本实施例提供的射频连接器 （为区分， 后续说明中称为第二射频连接 器） 与实施例一提供的射频连接器 （为区分， 后续说明中称为第一射频连接 器） 配合使用， 接合后的示意如图 2所示， 其中， 第一射频连接器 1包括： 第 一中心导体 11、 第一前端绝缘体 12、 第一后端绝缘子 13和第一外导体 14 , 第 一中心导体 11设置在第一外导体 14内， 第一前端绝缘体 12和第一后端绝缘子 13设置在第一中心导体 11与第一外导体 14之间； 第二射频连接器 2包括： 第二 中心导体 21、 第二绝缘体 22和第二外导体 23 , 第二中心导体 21设置在第二外 导体 23内， 第二绝缘体 22设置在第二中心导体 21与第二外导体 23之间。 其 中， 第一射频连接器 1的第一中心导体 11属于刚性接触件， 第二射频连接器 2 的第二中心导体 21的上端的弹性结构体 211属于弹性接触件， 当第一射频连接 器 1插入第二射频连接器 2时， 第一射频连接器 1的第一中心导体 11的接触部 111与第二射频连接器 2的第二中心导体 21的弹性结构体 211配合形成弹性接 触， 通过弹性结构体 211实现传输射频信号。
上述接合结构中， 第二射频连接器的第二中心导体的弹性结构体的多边 形开口的两个接触面之间开口缝隙的最小宽度不大于第一射频连接器的第一 中心导体的接触部的直径， 这样可以保证弹性结构体与第一中心导体的接触 部接触后， 具有一定的夹持力， 使第二射频连接器连接的开口多边型弹性结 构体可以很好的夹紧第一射频连接器的第一中心导体的接触部， 使两者能够 保持很好的弹性接触， 达到较好的弹性接触效果。 而第二射频连接器的第二 中心导体的弹性结构体的两个接触面之间开口依靠弹性可偏移的最大距离应 不小于射频连接器的规定达到的径向偏移量。 这样在第一射频连接器与第二 射频连接器连接时， 不会因第二射频连接器的第二中心导体的弹性结构体的 两个接触面偏移距离过小， 限制了整个射频连接器的径向偏移量。
可以根据第一射频连接器与第二射频连接器连接后需要达到的轴向偏移 量， 来设置第二射频连接器的第二中心导体上端的弹性结构体与第一中心导 体接触的接触段的长度， 要达到的轴向偏移量越大则该接触段的长度可相对 长一些， 反之该接触段则可以短一些。
图 3示意出本实施例提供的射频连接器中第二中心导体的弹性结构体 211 的一种结构， 该第二中心导体的弹性结构体 211包括两片相对设置的弹性体， 两片弹性体底部弧形连接， 两弹性体的中部为直段接触面， 上部为与中部直 段接触面呈一定角度的外张式开口。 这种结构的弹性结构体底部弧形部分使 相对的两片弹性体具有弹性夹持力， 中部的直段接触面与第一中心导体接触 部连接时， 可以夹持住第一中心导体的接触部 111。
使用图 3所示结构的弹性结构体 211 , 当第一射频连接器 1与第二射频连接 器 2接合时， 通过第二射频连接器 2的第二中心导体 21上端的弹性结构体 211的 竖直方向直段接触面与第一射频连接器 1的第一中心导体 11的圓柱形接触部形 成轴向 （图 3中点划线表示为轴向） 容差能力； 在与第一射频连接器 1的第一 中心导体 11圓柱形的接触部配合时， 通过第二射频连接器 2的第二中心导体 21 上端的弹性结构体的弹性变形形成径向容差能力， 从而实现第一射频连接器 1 与第二射频连接器 2接合时具有较大径向偏移量和轴向偏移量， 满足共面射频 浮动连接。 同时， 第二射频连接器 2的第二中心导体 21上端的弹性结构体的外 张式开口， 可形成对第一射频连接器 1的第一中心导体 11的圓柱形接触部的导 向能力， 满足快速插拔需求。
图 4示出了另一种结构的射频连接器， 该射频连接器中的第二中心导体的 弹性结构体 211与上述图 3中的射频连接器的弹性结构体的结构基本相同， 不 同的是该弹性结构体的底部弧形连接部的弧度较小， 这种结构不但节省材 料， 同时也可保证整个开口多边型弹性结构体对第一中心导体接触部的夹持 力。
本发明实施例的射频连接器的射频传输性能， 可通过调整第一射频连接 器 1的第一中心导体 11及设置在第一中心导体 11与第一外导体 14之间的第一前 端绝缘体 12和第一后端绝缘子 13的设计尺寸， 及调整第二射频连接器 2的第二 中心导体 21、 和第二外导体 23和夹持在第二中心导体 21和第二外导体 23之间 的第二绝缘体 22的设计尺寸， 达到减小第一射频连接器 1的第一中心导体 11和 第二射频连接器 2的第二中心导体 21外露空气部分的阻抗， 提高阻抗匹配， 进 而改善两射频连接器连接时的射频性能。
实施例三
在本实施例中， 弹性结构体 211的结构如图 5所示， 包括两片相对平行设 置的直段弹性体， 两片直段弹性体的开口处均设有导角形成外张式开口。 这 性体的中部的接触面与第一中心导体接触部连接时， 可以夹持住第一中心导 体的接触部 111 , 而上端导角形成的外张式开口可以方便第一中心导体接触部 111的插拔。
实施例四
在本实施例中， 弹性结构体 211的结构如图 6所示， 包括两片相对设置的 弹性体， 两片弹性体之间呈一定角度形成上宽下窄缝隙的弹性结构体。 这种
体与第一中心导体接触部连接时， 可以夹持住第一中心导体的接触部 111 , 而 两片弹性体之间形成开口宽下部窄的上宽下窄缝隙的结构， 可以方便第一中 心导体接触部 111的插拔。
实施例五
在本实施例中， 弹性结构体 211的结构如图 7所示， 包括两片相对设置的 弹性体， 两弹性体底部连接处呈锐角的 " Z " 形， 两弹性体的中部为直段接 触面， 上部为与中部直段接触面呈一定角度的外张开口。 这种结构的开口多 边型弹性结构体相对的两片弹性体通过底部的 " Z " 形连接部形成弹性夹持 力， 中部直段接触面与第一中心导体接触部连接时， 可以夹持住第一中心导 体的接触部 111 , 而上端导角形成的外张式开口可以方便第一中心导体接触部 111的插拔。
实施例二至实施例五提供的几种结构的射频连接器， 均可以与实施例一 提供的射频连接器接合形成共面射频浮动连接， 满足快速插拔需求。
可以知道， 本发明实施例中的第一射频连接器的第一中心导体与第二射 频连接器的第二中心导体接合处的结构也不限于上述图 3 ~图 7所示的几种结 构， 在不脱离本发明指导思想的前提下， 只要能实现第一射频连接器与第二 射频连接器接合后， 实现较大的径向偏移量和轴向偏移量， 及满足快速插拔 的需求即可。
实施例六
本实施例提供一种通信设备， 可以是一种无线通信设备， 该通信设备中 包括至少两块需射频连接的电路板， 如图 8所示， 其中一块电路板 3上设置上 述实施例一给出的第一射频连接器 1 , 而另一块电路板 4上设置上述实施例二 至五中给出的任一种结构的第二射频连接器 2 , 第一射频连接器 1的第一中心 导体的接触部设置在第二射频连接器 2的第二中心导体的弹性结构体的多边型 开口内， 第一中心导体的接触部与第二中心导体的弹性结构体实现弹性接触 连接， 实现两电路板的射频连接。
综上所述， 本发明实施例通过第一射频连接器的第一中心导体的接触部 与第二射频连接器的第二中心导体上端的弹性结构体配合实现弹性接触， 在 利用该射频连接器连接两电路板时， 可满足结构安装较大径向偏移量和轴向 偏移量要求， 突破了共面应用射频浮动连接瓶颈。 并且该射频连接器还可满 足了快速插拔需求， 其简单的结构可简化生产作业流程， 提升制造加工效 率。
以上所述， 仅为本发明较佳的具体实施方式， 但本发明的保护范围并不 技术领域的技术人员在本发明揭露的技术范围内， 可轻易想到的变化或替 换， 都应涵盖在本发明的保护范围之内。 因此， 本发明的保护范围应该以权 利要求的保护范围为准。
