具体实施方式
现详细参照本发明的优选实施例,实施例的实例图示在附图中。
图1示出本发明第一优选实施例的局部剖视图,图中显示的连接器100处于准备接纳波纹同轴电缆的状态。在图1中,绝缘体800、触头900、绝缘体700、环775以及内波纹构件400,借助于在本体300和内波纹构件400之间的轻微临时压配,已经在工厂安装和固定到本体300内。通过压迫偶联螺母200越过轻微干涉突起330,使压紧偶联螺母200固定在本体300周围,由此允许偶联螺母200围绕本体300旋转,作有限的轴向运动。内波纹的密封构件600设置在内波纹的构件400内。
图2示出波纹同轴电缆10的准备好的端部的局部剖视图,该波纹同轴电缆10包括中心导体15、电介体20、波纹外导体25以及电缆护套30。
图3示出连接器100的优选实施例的分解图,该连接器100包括本体300、偶联螺母200、绝缘体800、触头900、绝缘体700、环775、内波纹构件400、内波纹密封构件600,以及后部螺母500。上述零件在图3中从左至右依次排列。
本体300包括前端305、接口外直径310、外直径315、面向后的环形台肩320、外直径325、突起330、外螺纹部分335、后端340、内部孔345、350和355、面向后的环形槽360、通孔365、内部孔370以及环形套375。本体300较佳地用诸如黄铜之类的金属材料制造,并较佳地镀上诸如镍锡合金之类的导电、耐腐蚀的材料。
偶联螺母200包括前端205、内螺纹部分210、外表面215、后端217以及通孔220。偶联螺母200较佳地用诸如黄铜之类的金属材料制造,并较佳地镀上诸如镍锡合金之类的导电、耐腐蚀的材料。
绝缘体800包括前端805、突起的锥度的环形环810、外直径815、后端820、多个阻抗匹配孔825、内部孔830、面向后的环形表面833,以及通孔835。绝缘体800较佳地用诸如商标为TPX的聚甲基戊烯之类的电气绝缘材料制造。
触头900包括前端905、锥度部分910、直段部分915、突起920、外直径925、面向前的环形台肩930、外直径935、锥度部分940、内部孔945、多个触头尖950、多个狭槽955、后端960,以及可供选择的孔965。触头900较佳地用诸如铍铜之类的金属制造,且较佳地进行热处理并较佳地镀上诸如镍锡合金那样的导电、耐腐蚀的材料。
环775包括前端796、外直径778、后端781、锥度突出部分784、通孔787、内锥度区域790、以及内孔793。环775较佳地用诸如黄铜之类的金属制造,且较佳地镀上诸如银那样的导电、耐腐蚀的材料
内波纹构件400包括内波纹区域405、前端410、倾斜外表面415、外直径420、外凹表面425、外表面430、435和440、斜面445、内部孔450,以及后端455。内部孔450沿轴向的长度较佳地大于内波纹区域405沿轴向的长度。即,内波纹区域405较佳地做成小于内波纹构件400轴向长度的50%,甚至更佳地做成小于内波纹构件400轴向长度的30%。内波纹构件400较佳地用诸如商标为Delrin的乙缩醛之类的保形的塑料制造。
内波纹密封构件600包括前端605、外直径610、后端615以及内波纹区域620。内波纹密封构件600较佳地用橡胶状材料制造,诸如EPDM(三元乙丙橡胶),或替代地,用硅树脂制造。当内波纹密封构件600如图1所示地设置在内波纹构件400的内部孔450内时,它较佳地被内波纹构件400的具有外凹表面425的部分包围起来。较佳地,内波纹密封构件600的轴向长度小于内波纹构件400的轴向长度的30%。较佳地,内波纹密封构件600的轴向长度小于内波纹构件400的内部孔450的轴向长度的50%。
后螺母500包括前端505、内螺纹部分510、埋头孔515、外部形状520、外直径525、后端530、内锥度部分535、埋头孔537、埋头孔540、通孔545、通孔547,以及内部孔550。后螺母500较佳地用诸如黄铜之类的金属材料制造,并较佳地镀上诸如镍锡合金之类的导电、耐腐蚀的材料。
图4示出处于第一组装阶段的连接器100,其中,电缆10准备好的端部通过后螺母500插入连接器100内。电缆外导体25与内波纹密封构件600及内波纹构件400接合。内波纹构件400的外表面430具有比后螺母500的通孔545小的直径,而外表面435具有比后螺母500的通孔545大的直径,这样在内波纹构件400和后螺母500之间提供机械阻挡,限制内波纹构件400向前的轴向运动,由此,提供了内波纹构件400的前端410和环775之间的间隙。电缆外导体25的内部环形地设置在环775的锥度突出部分784的周围。电缆中心导体15通过绝缘体700,并借助于多个触头尖950作用的径向向内的压缩力,与触头900在机械上和电气上连通。
图5示出连接器100和电缆10处于第二组装阶段的局部剖视图,其中,后螺母500在本体300的螺纹部分335上螺旋地前进,由此,沿本体300的前端305的方向轴向地推进后螺母500,并启动内波纹构件400的后端455的径向向内的压缩运动。
图6示出连接器100和电缆10处于第三即最后组装阶段的局部剖视图。后螺母500完全地拧紧到本体300的螺纹部分335上,由此,完全地压紧内波纹构件400的后端455。内波纹密封构件600顺从于或至少部分地顺从于电缆10(具体来说,电缆外导体25)和内波纹构件400的轮廓。通过将内波纹构件400的后端455夹在中间,如图6所示,该后端455被后螺母500具体说被内部锥度部分535沿径向向内地压紧,于是,电缆护套30和后螺母500提供了机械的支承和对环境的密封。将内波纹密封构件600夹紧在电缆外导体25和内波纹构件400之间,这样提供了另外附加的机械的支承和对环境的密封。因此,通过两种夹紧和密封方式提供了双重的夹紧和密封机构,一种是将内波纹密封构件600夹紧在电缆外导体25和内波纹构件400之间提供的第一夹紧和密封,另一种是通过将内波纹构件400的后端455夹紧在后螺母500和电缆护套30之间提供的第二夹紧和密封。电缆外导体25形成为抵靠住内波纹构件400的内波纹区域405,抵靠住内波纹密封构件600的内波纹区域620,且电缆外导体25被夹紧或夹在内波纹构件400和环775的锥度部分784之间,在连接器100和电缆10之间提供了电气和机械的连通。
本技术领域内的技术人员将会认识到,对于本发明还可作出各种修改和变化,而不会脱离本发明的精神和范围。因此,本发明意欲涵盖落入附后权利要求书和其等价物范围之内的本发明的所有修改和变化。
