具有连续性构件的连接器
技术领域

背景技术
宽带通信已经成为越来越普遍的电磁信息交换形式,且同轴电缆是用于传输宽带通信的常用管线。同轴电缆通常设计成使得传送通信信号的电磁场仅仅在电缆的内部和外部同轴导体之间的空间中存在。这允许同轴电缆用以紧接金属物体安装,而没有在其它传输线路中发生的功率损失,且提供对通信信号的保护以防外部电磁干扰。同轴电缆的连接器通常连接到互补接口端口上,以将同轴电缆与各种电子装置和电缆通信设备电气地集成。连接通常通过将连接器的带内螺纹螺母围绕相应带外螺纹接口端口旋转来进行。完全拧紧同轴电缆连接器到接口端口的螺纹连接有助于确保连接器和相应接口端口之间的接地连接。然而,连接器通常未适当地拧紧或以其它方式安装到接口端口上,且连接器与接口端口的合适电配合并不发生。此外,常用连接器的结构可允许接地损失和电磁屏蔽的不连续性,电磁屏蔽旨在从电缆延伸通过连接器到达相应同轴电缆接口端口。

具体实施方式
虽然显示和详细描述某些实施例,但是应当理解,可在不偏离所附权利要求的范围的情况下作出各种改变和修改。本发明的范围绝不限于仅作为本发明实施例的示例公开的组成部件的数量、部件的材料、部件的形状、部件的相对布置等。
作为详细说明的前序,应当注意,如在说明书和所附权利要求书中所用的,单数形式“一”和“该”包括复数指代,除非上下文中另有明确指示。
参考附图,图1示出了同轴电缆连接器100的一个实施例,同轴电缆连接器100具有连续性构件75的实施例。同轴电缆连接器100可操作性地附接到同轴电缆10,从而电缆10固定地附连到连接器100。同轴电缆10可包括保护性外部护套12、导电接地屏蔽件14、电介质箔层15、内部电介质16和中心导体18。同轴电缆10可以制备成图1体现的那样,通过去除保护性外部护套12且往回拉导电接地屏蔽件14,以暴露环绕内部电介质16的电介质箔层15的一部分。所体现的同轴电缆10的进一步制备可包括剥离电介质箔层15和电介质16以暴露中心导体18的一部分。保护性外部护套12旨在保护同轴电缆10的各个部件不受损害,所述损害可能由暴露于灰尘或水分和由腐蚀引起。此外,保护性外部护套12在某种积度上可用于以包含电缆(contained cable)设计紧固同轴电缆10的各个部件,保护电缆10不受与电缆安装期间的移动有关的损害。导电接地屏蔽件14可以由适合于提供电接地连接的导电材料形成。可以采用屏蔽件14的各个实施例,以遮蔽不想要的噪音。例如,屏蔽件14可包括围绕电介质16卷绕的金属箔或者围绕电介质16以连续编织物形成的多个导电束。可以使用箔和/或编织束的组合,其中,导电屏蔽件14可包括箔层,然后编织层,然后箔层。本领域技术人员将理解,可以实施各种层组合,以便导电接地屏蔽件14实现电磁缓冲,从而有助于防止可能破坏宽带通信的环境噪音的进入。电介质16可包括适合于电绝缘的材料。应当注意的是,形成同轴电缆10的所有各个部件的各种材料应当具有一定程度的弹性,从而允许电缆10根据常规宽带通信标准、安装方法和/或设备折曲或弯曲。还应当认识到,同轴电缆10、保护性外部护套12、导电接地屏蔽件14、电介质箔层15、内部电介质16和/或中心导体18的径向厚度可基于通常认为与宽带通信标准和/或设备相对应的参数变化。
进一步参考图1,连接器100配置成附连到同轴电缆接口端口,例如接口端口20。同轴电缆接口端口20包括导电插孔,用于接收同轴电缆中心导体18的足以进行充分电接触的部分。同轴电缆接口端口20还可以包括带螺纹外表面23。应当认识到,同轴电缆接口端口20和/或端口20的导电插孔的径向厚度和/或长度可基于通常认为与宽带通信标准和/或设备相对应的参数变化。此外,可以在同轴电缆接口端口20的带螺纹外表面23上形成的螺纹的节距和高度也可基于通常认为与宽带通信标准和/或设备相对应的参数变化。此外,应当认识到,接口端口20可以由单种导电材料、多种导电材料形成,或者可以配置有导电和不导电材料两者,与端口20的与连接器100的有效电接口相对应。然而,接口端口20的插孔应当由导电材料形成。另外,本领域普通技术人员应当理解,接口端口20可以由同轴电缆通信装置、电视、调制解调器、计算机端口、网络接收器或其它通信改进设备(例如信号分配器、电缆线路扩展器、电缆网络模块和/或类似物)的连接接口部件实施。
继续参考图1,同轴电缆连接器100的实施例还可以包括端口联接元件(例如,螺母)30、接线柱40、连接器主体50、紧固件构件60和由导电材料形成的连续性构件75。
同轴电缆连接器100的实施例的螺母30或端口联接元件具有第一端31和相对的第二端32。螺母30可带螺纹且可旋转地紧固到接线柱40,以允许围绕接线柱的旋转运动。螺母30可包括内部唇缘34(如图2所示),内部唇缘34定位邻近或以其它方式靠近第二端32,且配置成妨碍接线柱40的轴向移动。螺母30还可包括内螺纹33,该内螺纹33从第一端31的边缘轴向地延伸足够的距离,以提供与标准同轴电缆接口端口20的外螺纹23的可操作有效的螺纹接触。螺母的结构构造可变化,以适应同轴电缆连接器100的不同功能。例如,螺母30的第一端31可包括内部结构和/或外部结构,例如脊部凹槽、弯曲部、掣子、槽、开口、斜面或其它结构特征等,它们可有利于诸如不漏水的密封件的环境密封构件的可操作结合,当与接口端口20配合时,环境密封构件可帮助防止环境污染物在螺母30的第一端31处进入。此外,螺母30的第二端32可延伸较大的轴向距离,以径向地接留连接器主体50的范围,但是螺母30的延伸部分不需要接触连接器主体50。螺母30或端口联接元件包括大致轴向的开口,如图1所示。螺母30可由导电材料制成,从而有利于通过螺母30进行接地。因此,螺母30可配置成:在连接器100前进到端口20上时,通过电接触接口端口20的导电表面来延伸电磁缓冲。另外,螺母30可由导电材料和不导电材料两者制成。例如,螺母30的外表面可由聚合物制成,而螺母30的其余部分可由金属或其它导电材料构成。螺母30可由金属或聚合物或将有利于刚性成型螺母主体的其它材料制成。带螺纹螺母30的制造可包括铸造、挤压、切割、压花、车削、攻丝、钻孔、注射模制、吹气模制或可提供有效部件生产的其它制造方法。本领域技术人员应当理解的是,螺母30的各个实施例还可以包括没有螺纹的联接器构件,但是定尺寸为可操作连接到相应接口端口,例如接口端口20。
仍然参照图1,连接器100的实施例可包括接线柱40。接线柱40包括第一端41和相对的第二端42。此外,接线柱40包括位于接线柱40的第二端42处的凸缘44,例如在外部延伸的环形凸起。凸缘44可包括面向接线柱40的第一端41的渐缩表面。腔室49位于沿凸缘44的某个位置,腔室49可以接纳、装纳、保持、容纳、接受、接收连续性构件75。位于沿凸缘44的某个位置的腔室49还可以是凹槽、掣子、挤压件、开口、孔、切口、空间、凹部、坑、凹陷等。例如,凸缘44的一部分可以被去除、切出等,从而形成腔室49以接纳连续性构件75。在一个实施例中,腔室49可以定位邻近接线柱40的第二端42。在另一个实施例中,腔室49可以位于凸缘44的外表面45上,靠近接线柱40的配合边缘46的表面。在又一个实施例中,腔室49可以位于凸缘44的外表面45上,其中,腔室49的开口面向接线柱40的第一端41。此外,腔室49的形状可以是圆形、半圆形、圆柱形、弧形、曲线形等,或者可选地腔室49的形状可以是多边形、矩形、方形等。本领域技术人员将理解,腔室49及其形状可以是从凸缘44切出的曲线形和多边形的组合。在许多实施例中,腔室49的形状或容积可以使得其可以接纳、装纳、保持、容纳、接受、接收等连续性构件75。例如,腔室49的容积或内部空间必须大于或等于在腔室49内紧固连续性构件75所需的容积。
另外,接线柱40的实施例可包括诸如唇缘或凸起的表面特征47,该表面特征47可接合连接器主体50的一部分,以固定接线柱40相对于连接器主体50的轴向运动。然而,接线柱可不包括这种表面特征47,且同轴电缆连接器100可以依赖于压配合和摩擦配合力和/或其它部件结构来帮助将接线柱40保持在相对于连接器主体50的轴向和旋转方向上的固定位置。连接器主体50相对于接线柱40紧固的位置附近或以其它方式相邻的位置可包括表面特征43,例如脊部、凹槽、凸起或压花,这可以增强接线柱40相对于连接器主体50的固定位置。此外,接线柱40可包括配合边缘46。配合边缘46可配置成与接口端口20的对应配合边缘26进行物理接触和电接触。接线柱40应当形成为使得已制备同轴电缆10的部分(包括电介质箔层15、电介质16和中心导体18)可轴向地通入第二端42中以及/或者穿过接线柱40的管状主体的一部分。此外,接线柱40应当定尺寸使得接线柱40可在环绕电介质16的电介质箔层15周围以及在保护性外护套12和导电接地屏蔽件14的下面插入已制备同轴电缆10的端部中。因此,在接线柱40的实施例可在往回拉的导电接地屏蔽件14下面插入已制备同轴电缆10的端部中时,可实现与屏蔽件14的实质上的物理接触和/或电接触,从而有利于通过接线柱40进行接地。接线柱40可由金属或将有利于刚性成型接线柱主体的其它导电材料制成。另外,接线柱40可由导电材料和不导电材料两者的组合制成。例如,可将金属涂层或层施用到聚合物或其它不导电材料上。接线柱40的制造可包括铸造、挤压、切割、车削、钻孔、压花、注射模制、喷涂、部件包覆模制(overmolding)或可提供有效部件生产的其它制造方法。
继续参考图1,连接器100的实施例可包括连续性构件75,其中,连续性构件75保持接线柱40和螺母30之间的电接地连续性。连续性构件75应当是导电的。此外,连续性构件75可以是有弹性的、易挠的、柔性的等。在一个非限制性示例中,连续性构件75可以由金属制成。连续性构件75可以是与接线柱40接触同时还与螺母30接触的构件、元件和/或结构,从而建立并保持它们之间的物理和电接触。所述接触可以是同时的而独立的。例如,如图2所示,连续性构件75的第一部分72可以接触接线柱40,而同时第二部分74接触螺母30。连续性构件75的进一步实施例可包括基部77、第一翼部78和第二翼部79。第一翼部78和第二翼部79可以从基部77凸起。在一个实施例中,第一翼部78和第二翼部79可以从基部77成角度地凸起。在另一个实施例中,第一翼部78和第二翼部79可以从基部77垂直地凸起。第一翼部78的远端(距基部77)可以与第二翼部79的远端相对。每个翼部78、79可以通过各种连接方法(例如,焊接连接)独立地固定到基部77。可选地,连续性构件75可以是一个相容的一致的构件,且可以成型为包括至少一个翼部78和基部77的结构。由于连续性构件75可以是有弹性的,因而在机械力施加到翼部78、79时,每个翼部78、79可以变形。例如,第二翼部79可以变形和/或顺从螺母30的唇缘34的表面或边缘,如图2-3所示,从而建立和保持接线柱40和螺母30之间的物理和电接触。在一些实施例中,连续性构件75可包括邻近第一翼部78和第二翼部79的第三翼部71,以利于与接线柱40和螺母30的物理和电接触。
连续性构件75的基部77可以紧固或定位在腔室49内,其中,腔室49位于沿接线柱40的凸缘44的某一位置。例如,连续性构件75的基部77可以紧固到腔室49的底表面49A,底表面49A可以距凸缘44的外表面45下方一定距离,如图1-3所示。基部77可以通过本领域技术人员人员已知的各种方法(例如,焊接连接、环氧树脂、螺栓、螺钉、压配合等)与腔室49的底表面49A紧固、固定、粘附、压配合、附连、摩擦配合、放置、定位、粘合等。可选地,连续性构件75不需要将其基部77永久性地固定到腔室49中的底表面49A。在操作性地组装时由于连接器100部件施加的机械力引起的径向压缩可以将连续性构件75保持和保留在腔室49内的可操作位置,从而进一步建立和保持与接线柱40和螺母30的物理和电接触。
连续性构件75的位置可以建立和保持接线柱40和螺母30之间的物理和电接触,这可以保持贯穿连接器100到接口端口20的接地连续性,甚至在连接器100可能未完全围绕接口端口20拧紧时也是如此。连接器100(例如,F型连接器)可以通过与接口端口20的导电外表面电连接而接地。保持贯穿连接器100的接地连续性可以通过在接线柱40的凸缘44上的腔室49中放置连续性构件75来完成。连续性构件75在腔室49中的放置和位置可避免连续性构件75的永久性变形、连续性构件75的移位和引起的连续性丧失。例如,连续性构件75的永久性变形、连续性构件75的移位和引起的连续性丧失可由于在将连接器100拧紧到接口端口20中时产生的轴向力引起。换句话说,当连接器100操作性地附连或以其它方式连接到接口端口20时,具体地当螺母30围绕接口端口20拧紧时,所暴露的连续性构件(即,位于接线柱和/或凸缘的表面上的构件)可在固定部件(即,接线柱40)的表面和自由旋转端口联接元件(即,带螺纹螺母30)之间挤压、撞击或施压(即,经受轴向力)。然而,将连续性构件75放置在腔室49中可提供对所施加轴向力的缓解,因为其可以避免在连接器100的两个部件(例如,接线柱40和螺母30)之间显著地挤压。除了避免变形和/或损坏之外,在接线柱40的凸缘44上的腔室49中放置连续性构件75建立和保持接线柱40和螺母30之间的物理和电接触,这可以保持贯穿连接器100到接口端口20的接地连续性。本领域技术人员应当理解,连续性构件75不需要固定到接线柱40且简单地接触螺母30,而可以可选地固定到螺母30同时简单地接触接线柱40,如在下文参考图6-8所示和所述。
仍参考图1,诸如连接器100的同轴电缆连接器的实施例可包括连接器主体50。连接器主体50可包括第一端51和相对的第二端52。此外,连接器主体50可包括邻近或以其它方式靠近主体50的第一端51的接线柱安装部分57,接线柱安装部分57构造成以防止两个部件50、40相对于彼此在平行于连接器100轴线的方向移动的方式将主体50相对于接线柱40的外表面的一部分紧固地定位,从而连接器主体50相对于接线柱40轴向地紧固。另外,连接器主体50可包括定位邻近或靠近连接器主体50的第一端51的外部环形凹部58。此外,连接器主体50可包括半刚性而柔顺的外表面55,其中,外表面55可构造成在第二端52由于紧固件构件60的操作而抵靠所接收同轴电缆10可变形地压缩时,形成环形密封件。连接器主体50可包括定位邻近或靠近连接器主体50的第二端52的外部环形掣子53。另外,连接器主体50可包括内表面特征,例如靠近或邻近连接器主体50的第二端52的内表面形成且构造成通过与电缆的齿状相互作用来增强已插入和接收的同轴电缆10的摩擦约束和夹紧的环形锯齿。连接器主体50可由诸如塑料、聚合物、可弯曲金属或有利于半刚性而柔顺的外表面55的复合材料的材料制成。另外,连接器主体50可由导电材料或不导电材料或其组合制成。连接器主体50的制造可包括铸造、挤压、切割、车削、钻孔、压花、注射模制、喷涂、吹气模制、部件包覆模制或其组合或可提供有效部件生产的其它制造方法。
进一步参照图1,同轴电缆连接器100的实施例可包括紧固件构件60。紧固件构件60可具有第一端61和相对的第二端62。另外,紧固件构件60可包括内部环形凸起,该内部环形凸起位于紧固件构件60的第一端61附近,且构造成与连接器主体50的外表面55上的环形掣子53配合且实现支撑(purchase)。此外,紧固件构件60可包括限定在第一端61和第二端62之间且轴向地延伸穿过紧固件构件60的中央通路65。如图2所示,中央通路65可包括斜面表面,该斜面表面可设置在具有第一直径的第一开口或内孔和具有第二直径的第二开口或内孔之间,第一开口或内孔设置成紧邻紧固件构件60的第一端61,第二开口或内孔设置成紧邻紧固件构件60的第二端62。当紧固件构件60操作以固定同轴电缆10时,斜面表面可用于可变形地压缩连接器主体50的外表面55。例如,当紧固件构件被压缩在连接器主体上的紧贴和紧固位置时,变窄的几何形状将压缩挤压电缆。另外,紧固件构件60可包括设置成紧邻或靠近紧固件构件60的第二端62的外表面特征69。表面特征69可有利于在连接器100的操作期间夹紧紧固件构件60。虽然将表面特征69显示为环形掣子,但是表面特征69可具有各种形状和大小,例如脊部、缺口、凸起、压花或其它摩擦或夹紧型设置。紧固件构件60的第一端61可延伸一定轴向距离,从而在紧固件构件60在同轴电缆100上压缩到密封位置时,紧固件构件60接触或保持大致邻近或大体上靠近螺母30。必要领域的技术人员应当认识到,紧固件构件60可由刚性材料制成,例如金属、硬塑料、聚合物、复合物等和/或其组合。此外,可通过铸造、挤压、切割、车削、钻孔、压花、注射模制、喷涂、吹气模制、部件包覆模制或其组合或可提供有效部件生产的其它制造方法来制造紧固件构件60。
同轴电缆连接器100可紧固到所接收同轴电缆10的方式也可类似于将电缆紧固到具有可插入压缩套筒的连接器上的方式,所述压缩套筒被推动到连接器主体50内以压靠并紧固电缆10。同轴电缆连接器100包括具有第一端51和第二端52的外部连接器主体50。主体50至少部分地环绕管状内接线柱40。管状内接线柱40具有第一端41和第二端42,该第一端41包括凸缘44,第二端42构造成与同轴电缆10配合且接触电缆10的外部导电接地屏蔽件或鞘套14的一部分。连接器主体50紧固到管状接线柱40,使得连接器主体接合管状接线柱40的邻近或靠近管状接线柱40的第一端41的部分。连接器主体50与内接线柱40同轴地协作或者以与内接线柱40径向隔开的关系功能性地定位,以限定具有后部开口的环形室。管状锁定压缩构件或紧固件构件60可通过环形室的后部开口轴向地凸起到环形室中。管状锁定压缩构件可以可滑动地联接或其它方式可移动地固定到连接器主体50上以压缩到连接器主体内且保持电缆10,且可在第一打开位置(接纳管状内接线柱40插入已制备电缆10端部中,以接触接地屏蔽件14)和第二夹紧位置(将电缆10可压缩地固定在连接器100的室内)之间轴向地或者在连接器100的大致轴线方向移置或移动,因为压缩套筒或紧固件构件60被挤压成保持与连接器主体50内的电缆10接触。在如图2所示组装时,在内接线柱40的前端处的端口联接元件或螺母30用来将连接器100附连到接口端口上。在具有可插入压缩套筒的连接器中,螺母30的结构构造和功能操作可类似于图1-9中描述的且具有类似地指示的附图标记的连接器100、200、300和/或400的类似部件的结构和功能。
现在转向图4,连接器200可包括连续性构件275,连续性构件275可以是具有翼部278和脊部277的L形构件,其中,连续性构件275的第一部分272可位于腔室249中,连续性构件275的第二部分274可位于接线柱腔室248中。连续性构件275应当是导电的。此外,连续性构件275可以是有弹性的、易挠的、柔性的等。在一个非限制性示例中,连续性构件275可以由金属制成。连续性构件275可以是与接线柱240接触同时还与螺母230接触的构件、元件和/或结构,如图5所示,从而建立并保持螺母230和接线柱240之间的物理和电接触。所述接触可以是同时的而独立的。例如,连续性构件275的第一部分272可以接触接线柱240,而同时第二部分274接触螺母230。此外,翼部278可以从基部277垂直地或成角度地凸起,以建立和保持与螺母230接触。翼部278可以通过各种连接方法(例如,焊接连接)固定到基部277。可选地,连续性构件275可以是一个相容的一致的构件,且可以成型、弯曲、模制等成利于接线柱240和螺母230之间的电和物理连通的任何形状。由于连续性构件275可以是有弹性的,因而在机械力施加到翼部278时,翼部278可以变形。例如,如图5所示,翼部278可以变形和/或顺从螺母230的唇缘234的表面或边缘,从而建立和保持接线柱240和螺母230之间的物理和电接触。
此外,连续性构件275的基部277可以紧固或定位在接线柱腔室248内,其中,接线柱腔室248位于沿接线柱240的某一位置。在许多实施例中,接线柱腔室248可定位邻近凸缘244。例如,连续性构件275的基部277可以紧固或定位以接触接线柱腔室248的底表面248A。接线柱腔室248可以是腔室、凹部、掣子、沟槽、空间、开口、孔、挤压件、凹陷等。此外,接线柱腔室248可以由通过去除接线柱240外表面上的表面特征243(例如脊部、凹槽、凸起或压花)的部段而产生的切口、挤压件或空间形成。接线柱腔室248的空间或轮廓可以与基部277的形状相对应。在一个实施例中,接线柱腔室248的形状或周长可以稍大于基部277的形状或周长,以接纳、装纳、容纳、保持、接受、接收等连续性构件275的基部277。本领域技术人员将认识到,接线柱腔室248的深度可足以充分地允许基部277配合在接线柱240内且与接线柱240的外表面齐平。连续性构件275(例如基部277)设置稍微高于或低于接线柱240的外表面的细微偏差可能发生,而不实质地影响连续性构件275的性能。基部277可以通过本领域技术人员人员已知的各种方法(例如,焊接连接、环氧树脂、螺栓、螺钉、压配合等)与接线柱腔室248的底表面248A紧固、固定、粘附、压配合、附连、放置、定位、粘合等。可选地,连续性构件275不需要将其基部277永久性地固定到接线柱腔室248中的底表面248A。例如,在操作性地组装时由于连接器200部件施加的机械力引起的径向压缩可以将连续性构件275保持和保留在接线柱腔室248内的可操作位置,从而进一步建立和保持与接线柱240和螺母230的物理和电接触。
当基部277位于接线柱腔室248时,翼部278可以位于腔室249中,腔室249位于凸缘244的外表面245上。腔室249可以接纳、装纳、保持、容纳、接受、接收等连续性构件275(具体地为翼部278)。腔室249还可以是凹槽、掣子、挤压件、开口、孔、切口、空间、凹部、坑、凹陷等。例如,凸缘244的一部分可以被去除、切出、挤压等,从而形成腔室249以接纳连续性构件275的一部分。在一个实施例中,腔室249可以定位邻近接线柱240的第二端242。在另一个实施例中,腔室249可以位于凸缘244的外表面245上,靠近接线柱240的配合边缘246的表面。在又一个实施例中,腔室249可以位于凸缘244的外表面245上,其中,腔室249的开口面向接线柱240的第一端241。此外,腔室249的形状可以是圆形、半圆形、圆柱形、弧形、曲线形等,或者可选地腔室249的形状可以是多边形、矩形、方形等。本领域技术人员将理解,腔室249可以是从凸缘244切出的曲线形和多边形的组合。在许多实施例中,腔室249的形状或容积可以使得其可以接纳、装纳、保持、容纳、接受、接收等连续性构件275的一部分。例如,腔室249的容积或内部空间必须大于或等于在腔室249内紧固、保持、接纳、装纳、接收、接受等连续性构件275的一部分所需的容积。
连续性构件275的位置可以建立和保持接线柱240和螺母230之间的物理和电接触,这可以保持贯穿连接器200到接口端口20的接地连续性。连接器200(例如,F型连接器)可以通过与接口端口20的导电外表面电连接而接地。保持贯穿连接器200的接地连续性可以通过在接线柱240的凸缘244上的腔室249中放置连续性构件275的一部分或翼部278且在接线柱腔室248中放置连续性构件275的另一部分或基部277来完成,如图4和图5所示。连续性构件275的放置和位置可避免连续性构件275的永久性变形、连续性构件275的移位和引起的连续性丧失。例如,连续性构件275的永久性变形、连续性构件275的移位和引起的连续性丧失可由于在将连接器200拧紧到接口端口20中时产生的轴向力引起。换句话说,当连接器200操作性地附连或以其它方式连接到接口端口20时,具体地当螺母230围绕接口端口20拧紧时,所暴露的连续性构件(即,位于接线柱和/或凸缘的表面上且在其上方延伸的构件)可在固定部件(即,接线柱240)的表面和自由旋转联接元件(即,带螺纹螺母230)之间挤压、撞击或施压(即,经受轴向力)。然而,将连续性构件275的一部分放置在腔室249中且将连续性构件275的另一部分放置在接线柱腔室248中可提供对所施加轴向力的缓解,因为其可以避免在连接器200的两个部件(例如,接线柱240和螺母230)之间显著地挤压。除了避免变形和/或损坏之外,在接线柱240的凸缘244上的腔室249中放置连续性构件275的第一部分272且在接线柱腔室248中放置连续性构件275的第二部分274建立和保持接线柱240和螺母230之间的物理和电接触,这可以保持贯穿连接器200到接口端口20的接地连续性。
现在参考图6-8,连续性构件375可以定位邻近或以其它方式靠近接线柱340的凸缘344,其中,连续性构件375的第一部分372与凸缘344的下侧345接触,连续性构件375的第二部分374与端口联接元件(例如,螺母330)的内表面335接触。例如,螺母330可以包括键槽336,键槽336可以从第二端332开始且朝向第一端331延伸一定距离。键槽336可以不延伸从第二端332到第一端331的整个距离。例如,键槽336可以朝向第一端331延伸与连续性构件375的翼部378的长度相对应的距离,从而翼部378紧贴地或以其它方式配合在键槽336的参数内。然而,图8示出了螺母330的实施例,螺母330具有延伸螺母330的整个长度的键槽336,具体地,从第二端332延伸到第一端331。键槽336可以是位于螺母330的内直径上的开口、缺口、沟槽、槽道、切口、凹槽、路径、通道、掣子和/或槽。例如,螺纹333的一部分可以被去除、切出、成型等,以展现大致平滑内表面335,其中,内表面335低于螺纹33表面一定距离,如图8所示。换句话说,键槽336可以产生轴向延伸穿过螺纹333的容积或空间,其中,键槽336所产生的空间可以装纳、接收、保持、接纳等连续性构件375的一部分。键槽336可以将端口联接元件或螺母330的内直径增加与键槽336宽度相等的距离,因为内表面335可能不与螺纹333齐平。例如,键槽336可防止螺母330的内直径在沿螺母330的内周边所有点处基本上类似。在一个实施例中,键槽336可以接纳连续性构件375的翼部378,其中,翼部378与位于键槽336内的螺母330内表面335直接接触。在另一个实施例中,键槽336可以接纳连续性构件375的第二部分374,其中,连续性构件375的第一部分372围绕凸缘344定位。此外,连续性构件375的翼部378或第二部分374与螺母330的内表面335之间的接触可以建立和保持接线柱340和螺母330之间的物理和电接触。由于连续性构件375的翼部378或第二部分374与螺母330接触,而连续性构件375的基部377或第一部分372与接线柱340独立地且同时地接触,因而可以建立和保持接线柱340和螺母330之间的物理和电接触。连续性构件375的基部377可以与凸缘344的下侧345直接接触,如图6和7所示。凸缘344的下侧345可以是渐缩表面,这可以利于和/或确保与基部377的足够和一致的接触。
连续性构件375的翼部378或第二部分374可以紧固或定位在键槽336内,其中,键槽336位于沿螺母330的内直径的一定位置。例如,连续性构件375的翼部378可以紧固到螺母330的内表面335,内表面335可以在螺纹333的表面下方一定距离。翼部378可以通过本领域技术人员人员已知的各种方法(例如,焊接连接、环氧树脂、螺栓、螺钉、压配合等)与内表面335紧固、固定、粘附、压配合、附连、放置、定位、粘合等。可选地,连续性构件375不需要将其翼部378永久性地固定到键槽336中的内表面335。在操作性地组装时由于连接器300部件(例如,已联接接口端口)施加的机械力引起的径向压缩可以将连续性构件375保持和保留在键槽336内的可操作位置,从而进一步建立和保持与接线柱340和螺母330的物理和电接触。另外,连续性构件375应当是导电的,且可以是有弹性的、易挠的、柔性的等。在一个非限制性示例中,连续性构件375可以由金属制成。
在连接器300的操作期间,螺母330或联接元件可以旋转,以便与端口(例如,接口端口20)联接,这可导致螺母330围绕接线柱340旋转。当通过键槽336的参数或侧壁定位在键槽336中时,连续性构件375的翼部378或第二部分374的横向移动可以被限制和/或阻止。因而,当螺母330旋转时,连续性构件375的基部377或第一部分372可以围绕凸缘344旋转,以避免连续性构件375的任何损坏或永久性变形。例如,基部377可以围绕凸缘344旋转,同时保持与凸缘344的下侧345物理接触。
此外,连续性构件375的位置可以建立和保持接线柱340和螺母330之间的物理和电接触,这可以保持贯穿连接器300到接口端口20的接地连续性。连接器300(例如,F型连接器)可以通过与接口端口20的相互作用而接地。连续性构件375的一部分在穿过螺母330的螺纹333的键槽336中的放置和位置可避免连续性构件375的永久性变形、连续性构件375的移位和引起的连续性丧失。例如,连续性构件375的永久性变形、连续性构件375的移位和引起的连续性丧失可由于在将连接器300拧紧到接口端口20中时产生的轴向力引起。换句话说,当连接器300操作性地附连到端口20时,所暴露的连续性构件(即,位于螺纹333上的构件)可在固定部件(即,端口20)的表面和自由旋转端口联接元件(即,带螺纹螺母330)之间挤压、撞击或施压(即,经受轴向力)。然而,将连续性构件375的一部分放置在键槽336中可提供对所施加轴向力的缓解,因为其可以避免在连接器300的两个部件(例如,端口20和螺母330)之间显著地挤压。除了避免变形和/或损坏之外,将连续性构件375的一部分放置在螺母330上的键槽336中且将另一部分放置在凸缘344的下侧345上可建立和保持接线柱340和螺母330之间的物理和电接触,这可以保持贯穿连接器300到接口端口20的接地连续性。
进一步参考图1-9,连接器400可包括连续性构件75、275或375,且还可以包括主体密封构件80,例如O形环,具体地在图9中示出。主体密封构件80可在螺母30的内部唇缘34的前面位于螺母30的第二端部37附近,使得密封构件80可以可压缩地搁靠在螺母30和连接器主体50之间。主体密封构件80可在主体50的与在主体50的第一端51附近的环形凹部58相对应的部分上紧贴地配合。但是,本领域技术人员应当理解,可采用与螺母30和主体50的其它结构构造相对应的密封构件80的其它位置,以可操作地对环境污染物的进入提供物理密封和屏障。例如,主体密封构件80的主体实施例可以与同轴电缆连接器100一起构造和操作性地组装,以防止螺母30和连接器主体50之间的接触。
参考图1-9,一种用于保持与端口20的接地连续性的方法可包括步骤:提供同轴电缆连接器100,所述同轴电缆连接器100包括:能围绕接线柱40旋转的连接器主体50,所述接线柱40具有第一端41和相对的第二端42,其中,所述接线柱40包括邻近接线柱40第二端42的凸缘44;能围绕接线柱40旋转的端口联接元件30,其中,所述端口联接元件30具有内部唇缘34;和位于腔室49内的连续性构件75,所述腔室49位于接线柱40的凸缘44的外表面45上,其中,所述连续性构件75的第一部分72与端口联接元件30物理和电接触,所述连续性构件75的第二部分74与接线柱40物理和电接触;以及将连接器100的端口联接元件30前移到接口端口20上以将连接器100接地。所述方法可包括参考本文所述多个实施例的步骤。例如,保持接地连续性的方法可总体地或部分地结合连接器100、200、300和400的各方面。
尽管已经结合上述特定实施例来描述本发明,但显然地,多种改变、修正和变化对于本领域技术人员将是显而易见的。因此,上述本发明的优选实施例旨在示例性的,而不是限制性的。在不脱离如所附权利要求所限定的本发明精神和范围的情况下,可以做出多种变化。权利要求提供了本发明的覆盖范围并且不应当限于本文所提供的特定示例。
