第二屏蔽壳150包括下屏蔽框151和下屏蔽壳152。其中，下屏蔽框151包裹着绝缘嵌合部111的外侧，下屏蔽壳152覆盖着绝缘固持部112的下侧。
屏蔽加强壳160包括依次设置的前沿屏蔽板161、连接板162和固持板163，固持板163与绝缘固持部112连接，前沿屏蔽板161与绝缘嵌合部111连接，前沿屏蔽板161的宽度大于下屏蔽框151的厚度，在与插座连接器200配合连接时，第三屏蔽壳240与前沿屏蔽板161和下屏蔽框151相互接触连接。
在一实施例中，如图6和图8所示，第一屏蔽隔片130包括屏蔽嵌合段131和屏蔽固持段133，屏蔽嵌合段131设置在绝缘嵌合部111上，屏蔽固持段133设置在绝缘固持部112上，屏蔽固持段133的上侧表面与第一屏蔽壳140相接，屏蔽固持段133的下侧表面与屏蔽加强壳160相接，可以有效防止射频信号从相邻两同轴线缆300分别传输到对应的第一信号端子120过程中发生干涉，产生信号干扰。
在一实施例中，绝缘嵌合部111的后侧设置有凹槽结构1111，第一屏蔽隔片130设置有加强连接槽132，前沿屏蔽板161与凹槽结构1111和加强连接槽132配合连接。如图4-图8所示，绝缘嵌合部111上设置有与前沿屏蔽板161厚度相同的凹槽结构1111，第一屏蔽隔片130的屏蔽嵌合段131和屏蔽固持段133之间设有加强连接槽132，当第一屏蔽隔片130在第一绝缘座110上安装好时，凹槽结构1111和加强连接槽132共同构成与前沿屏蔽板161尺寸匹配的凹槽，安装好前沿屏蔽板161后，前沿屏蔽板161的下侧表面与绝缘嵌合部111的下侧表面平齐。
在一实施例中，如图3和图4所示，屏蔽加强壳160还包括触角结构164，触角结构164与绝缘嵌合部111的侧壁后侧卡接。设置触角结构164，使得屏蔽加强壳160与第一绝缘座110卡接在一起，在生产过程中不会轻易与第一绝缘座110脱离，进而有利于提高生产效率。在一实施例中，触角结构164对称设置在连接板163的两侧，即连接板163的两侧壁的下方分别向前延伸，然后形成与绝缘嵌合部111的侧壁后侧形状吻合的触角结构164，结构简单，便于加工和生产。
在一实施例中，如图14和图15所示，下屏蔽框151相对设置的一对侧壁内侧设有嵌合舌片1512，嵌合舌片1512用于增强第二屏蔽壳150与对接连接器 的嵌合强度。例如，下屏蔽框151相对设置的一对侧壁的上侧端部沿着内侧方向向下侧延伸弯折形成嵌合舌片1512，第一绝缘子110的绝缘嵌合部111上设有用于容置嵌合舌片1512的舌片容置槽1112。插座连接器200的第二绝缘座210上设置有舌片插接槽213。当射频连接器组件在使用时，插头连接器100与插座连接器200插接，此时，嵌合舌片1512嵌入舌片插接槽213内，第三屏蔽壳240位于嵌合舌片1512与下屏蔽框151之间，增强了插头连接器100与插座连接器200的嵌合强度，提高了射频连接器组件柔性插拔能力，使得操作人员的插拔插头连接器的手感明显。
在一实施例中，嵌合舌片1512自下侧端部至其上侧，嵌合舌片1512与设置该嵌合舌片1512的下屏蔽框151的侧壁所在平面之间距离，总体呈现先减小再增大的趋势。在嵌合舌片1512下侧端部，嵌合舌片1512与相应侧壁之间的距离较大，具有插接导引作用，易于将插头连接器与插座连接器连接对插在一起，而在嵌合舌片1512靠近中间的位置处，与相应侧壁之间的距离最小，使得操作人员插拔手感明显，提高操作体验，能够清楚明了的了解插头连接器与插座连接器的插接程度。
在一实施例中，固持板163上设有固定舌片1631，固定舌片1631用于固定屏蔽加强壳160。在插头连接器的实际生产过程中，会通过锡焊工艺将第一屏蔽隔片130、第一屏蔽壳140、第二屏蔽壳150和屏蔽加强壳160固定在一起，固持板163上设置固定舌片1631可以有效增加焊接面积，提高焊接结构的稳定性。
在一实施例中，绝缘固持部111的上侧与绝缘嵌合部112的上侧在同一表面，绝缘固持部112的厚度大于绝缘嵌合部111的厚度。如图2和图4所示，第一绝缘座110呈台阶型结构，绝缘嵌合部111的厚度小，与插座连接器进行插接配合后，整个射频连接器组件对应部分的厚度也较小，有利于满足当今产品小型化、微型化的发展需求。
在一实施例中，参见图6，填充的锡膏可显示为170，用于填充第一屏蔽隔片130与第一屏蔽壳140之间的间隙，形成封闭的全屏蔽。
如图9-图13所示，本实施例提供一种射频连接器组件，包括上述任一种插头连接器100和插座连接器200，其中，插座连接器200包括第二绝缘座210、设置在第二绝缘座210上的两个第二信号端子220，设置在第二绝缘座210上且位于两个第二信号端子220之间的第二屏蔽隔片230，以及环设在第二绝缘座210外侧的第三屏蔽壳240。
插头连接器100与插座连接器200配合连接时，如图10和图11所示，第 三屏蔽壳240的外壁与下屏蔽框151的内壁和屏蔽加强壳160相接，可以有效防止射频信号泄露引起信号干扰；第一信号端子120与第二信号端子220接触，实现电性接触以传输电力和/或信号；第一屏蔽隔片130和第二屏蔽隔片230配合连接，形成两个防止发生信号干涉的屏蔽空间。
在一实施例中，第一屏蔽隔片130上设有嵌合凸起1311，第二屏蔽隔片230上设有与嵌合凸起1311相匹配的嵌合凹槽232。在插头连接器100与插座连接器200配合连接时，嵌合凸起1311与嵌合凹槽232相互配合，形成两个防止发生信号干涉的屏蔽空间。
如图12和图13所示，第二绝缘座210上设有第一通孔结构211和第二通孔结构212。第二信号端子220包括第二接触部221、第二连接部222和第二固定部223。第二屏蔽隔片230的上固持面231与第二绝缘座210的上侧表面平齐，第二屏蔽隔片230的下固持面233与第二绝缘座210的下侧表面平齐，在上固持面231上向下形成一个与嵌合凸起1311尺寸相互吻合的嵌合凹槽232。第二接触部221设置在第一通孔结构211中，嵌合凹槽232设置在第二通孔结构212中。
在一实施例中，下屏蔽框151的内壁设有卡位凸起1511，第三屏蔽壳240的外壁设有卡位凹槽241，当插头连接器100与插座连接器200配合连接时，卡位凸起1511与卡位凹槽241配合连接，以增强插头连接器100与插座连接器200的插接强度，从而提高射频连接器组件的信号传输的稳定性。
在一实施例中，第三屏蔽壳240的下侧底板外沿设置有护边结构242。
在一实施例中，第一接触部121为双层贴合结构，此时，第一接触部121的厚度变为其它区域厚度的两倍，相对于均匀厚度的普通传统信号端子而言，第一接触部121因其具备两倍的厚度，为保证传输通道的相同的阻抗(通常为50欧姆)的要求，其宽度可以缩小为普通信号端子的一半左右，从而使得两个第一信号端子120的距离隔开得更大，间隔距离更远，因而，具备更好的防止信号干扰的隔度效果。另外，由于将第一接触部121设置为双层贴合结构，与插座连接器的第二信号端子220连接时，第一接触部121的厚度增大，会给第二信号端子220与第一接触部121的连接面一定的压力，从而可以增强接触强度，双层结构设置为贴合的，即形成双层结构的两个分支隔片之间没有间隙，不会形成电容效应，从而防止存在空隙发生高频谐振现象。因此，将第一接触部121设置为双层贴合结构，不仅可以提高两个插头信号端子之间的屏蔽效果，而且还可以防止出现高频谐振现象，同时还可以提高插头信号端子与插座连接 器中插座信号端子的接触强度与连接稳定性。
为了解决相关技术中射频连接器公端组件，存在电场泄露、信号干扰等状况，本申请中插头连接器通过设置第一屏蔽隔片和屏蔽加强壳，在与插座连接器配合连接时，第一屏蔽隔片与插座连接器中的第二屏蔽隔片配合形成两个防止信号互相干扰的屏蔽空间，屏蔽加强壳、第二屏蔽壳与插座连接器的第三屏蔽壳连接，可以实现全封闭屏蔽，从而可以降低与电磁干扰(Electromagnetic Interference，EMI)及射频干扰相关的辐射，防射频泄漏，并可将对外部磁场的敏感度降至最低，具有优异的屏蔽性能、抗干扰能力和电学性能。
所述镶嵌成型是指在模具内装入预先准备的异材质嵌件后注入树脂，熔融的材料与嵌件接合固化，制成一体化产品的成型方法。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
