Description

激光焊接同轴连接器以及互连方法
技术领域
本发明涉及电缆连接器。更具体地，本发明涉及能够通过激光焊接互连的同轴线缆连接器。
背景技术
同轴线缆连接器例如在要求高精度和高可靠性的通信系统中使用。
为了在线缆和连接器之间创造牢固的机械互连和优化的电气互连，理想的是在同轴线缆外导体的前边缘和连接器主体之间具有基本均匀的圆周接触。可以通过联接主体将外导体的扩口端部夹持抵靠在连接器主体的环形楔面上。这种技术的代表是2004年9月21日授予Buenz的共同拥有的美国专利No.6793529。虽然这种连接器通常是可以拆卸/重复使用的，但是由于所需多个分开的内部元件、互连螺纹和相关环境密封件而使制造和安装复杂。
业内还已知有被配置为通过焊接和/或粘合互连永久互连的连接器。这种技术的代表是1998年9月8日授予Bufanda等人的共同拥有的美国专利No.5802710。但是焊接和/或粘合互连难以赋予高水平的质量控制，从而导致互连可能不令人满意，例如当长期暴露在振动和/或腐蚀环境下时。
同轴线缆连接器市场上的竞争已经聚焦于提高线缆-连接器互连的电气性能、互连质量一致性和长期可靠性。另外，整体成本（包括材料、培训和安装成本）的减少也是非常重要的商业成功因素。
因此，本发明的目的是提供克服现有技术中的缺陷的一种同轴连接器和互联的方法。

具体实施方式
对于同轴电缆的导体来说已将铝作为铜的有成本效益的替代物。但是，铝表面一旦暴露在空气中就会很快地形成氧化铝表面涂层。这些氧化铝表面涂层可使常规的机械互连、焊接互连和/或导电粘合互连劣化。
发明人已经认识到：具有铝和/或铝合金固态外部导体的同轴线缆的增加的接受度使连接器能够构造成通过激光焊接形成如下外部导体和连接器主体之间的互连：所述外部导体和连接器主体也可以例如由铝和/或铝合金有成本效益地提供。
在图1-4中示出可激光焊接的同轴连接器2的示范性实施例。如图4中所最佳示出的，整体的连接器主体4设置有尺寸设计为接收穿过其中的同轴线缆9的外部导体8的前边缘的孔洞6。为了定位成通过激光焊接互连，外部导体8的前边缘延伸穿过孔洞6至在连接器端部18处与连接界面14的肩部10的边缘基本上齐平的纵向位置，从而呈现朝向连接器端部18的共同端部面，如图5中所最佳示出的。连接界面14可以为任何所需的标准或专用连接界面14，其包括通向孔洞6和外部导体8之间的圆周接触接缝16的入口，接缝16基本上平行于同轴连接器2的纵向轴线。
本领域的技术人员将理解的是，连接器端部18和线缆端部12在本文中分别作为同轴连接器2的端部以及本文描述的同轴连接器2的离散元件的端部的标识符，以根据它们沿着连接器端部18和线缆端部12之间的连接器2的纵向轴线的对准来识别相同及其各自的互连表面。
在将孔洞6的直径选择为关于外部导体8的直径成紧密公差配合的情况下，可以执行外部导体8和连接器主体2之间的激光焊接互连而无需添加其他材料（诸如焊接棒或线）。可以将用于外部导体8和连接器主体2之间的接缝16的激光的高水平局部加热应用为指向目标部位的脉冲，其中连续的脉冲应用于重叠点部分以形成外部导体8和连接器主体2的相邻部分之间的连续焊接。
在通过激光焊接互连之前，可以通过切断线缆9使得内部导体24从外部导体8延伸而将线缆9的端部预备好，如图6中所最佳示出的。还有，可以剥掉内部导体24和外部导体8之间的介电材料26并且移除一段外部护套28以暴露每个所需的的长度。介电材料26的一部分可以设置为延伸到外部导体8的前边缘之前，例如作为互连阻抗中断减小特征。
在可应用的情况下，线缆端部预备还可以包括以下步骤：使线缆端部部分变直，以例如消除由于以卷轴形式缠绕的线缆的成批线缆运输所导致的线缆中的任何弯曲，以使得当被插入至孔洞6内时，线缆端部沿其长度与孔洞6同轴并且内部导体24从平行于孔洞6的纵向轴线的连接器端部18突出。因此在孔洞侧壁20和外部导体8的外径之间的接缝环绕外部导体8的圆周为均匀的，从而增加了产生的激光焊接的均匀性。
因为激光焊接工艺的局部加热能够破坏邻近焊接区域中的氧化铝表面覆层，所以可以不需要额外关注移除或者以其他方式处理互连表面上的氧化铝的存在。
例如在图10的示例中所示的包壳30可以应用于连接器主体4作为聚合材料的包覆模制件。包壳30增加了线缆至连接器扭转和牵拉阻力。包壳30还可以提供在连接器端部18处的连接界面结构以及在线缆端部12处的进一步增强支承，从而使连接器主体4的尺寸显著减小，因此降低整体材料成本。
根据所应用的连接界面14（在本文的示范性实施例中作为标准7/16DIN界面示出），包壳30可以设置有包壳凸缘32和用于联接螺母36的纵向支承脊34。联接螺母36在连接器端部18处通过包壳凸缘32、以及在线缆端部12处通过设置于支承脊34中至少之一上的保持凸起38被保持于支承脊34上。保持凸起38可以朝向连接器端部18形成一定角度，从而容许联接螺母36安放于互连过程中最初从同轴连接器2间隔开的线缆9（参见图1）上，随后容许联接螺母36从线缆端部12经过保持凸起38到支承脊34上，之后紧邻连接器界面14通过保持凸起38（参见图2）保持于支承脊34上，以实现连接器至连接器配合。支承脊34在向连接器/互连2提供侧向强度以及联接螺母36的对齐和保持的同时减少对包壳30的聚合材料的需要。
包壳30还可以从连接器主体4的连接器端部18延伸以提供部分选定的连接界面14（诸如7/16DIN界面的对准圆筒体39），从而进一步减少对连接器主体4的金属材料的需要。
包壳凸缘32可以通过设置于连接器主体凸缘40和/或连接器主体4的外径中的一个或多个互锁孔42（诸如洞）、纵向滚花43、沟槽、凹口45等牢固地键合至连接器主体4的连接器主体凸缘40，并且由此牢固地键合至连接器主体4，如图7-9中所示。因此，当包壳30的聚合材料在包覆模制过程中流动至互锁孔42内时，一旦固化包壳30就被永久地联接至连接器主体4并且与其可旋转地互锁，例如如图10中所示。
如图11中所最佳示出，包壳30的线缆端部12的尺寸可以被设计为具有靠近同轴线缆外部护套28的表面的内径摩擦表面44，从而在激光焊接连接器主体4和外部导体之前能够形成包壳30和外部护套28之间的聚合摩擦焊接，因此无需在连接器/线缆互连的线缆端部12处的环境密封件。在摩擦焊接过程中，同轴连接器2相对于线缆9旋转。摩擦表面44和外部护套28的外径之间的摩擦将各自的表面加热到摩擦表面44和外部护套28开始变软并混合的程度，从而使摩擦表面44和外部护套28抵靠彼此密封。为提供增强的摩擦并且容许用于由摩擦位移导致的过度流动的空隙以及增加用于额外强度的键合锁定，外部护套28和/或包壳30的内径可以设置为具有轮廓图案（诸如例如在图12中示出的波状物46、或例如在图13中示出的阶梯表面48）的多个间隔环形突起。替代地，在与外部导体8互连后，包壳30可以通过粘合剂/密封剂密封抵靠在外部护套28上或者可以被包覆模制在连接器主体4上，注射的聚合材料的热量使包壳30与外部护套28结合和/或密封抵靠在外部护套28上。
从同轴线缆9的预备好的端部延伸的内部导体24可以选定为穿过到达作为选定连接界面14的一部分的连接器端部18，例如在图8中所示。如果选定的同轴线缆9的内部导体24具有与选定的连接界面14的内部导体部分相比更大直径的话，那么内部导体24可以在连接器端部18处被磨削至所需的直径。
虽然使内部导体24直接穿过有利地消除了互连（例如通过传统的同轴连接器内部触点的弹簧篮（springbasket）），但是这可以导致诸如PIM的电气性能劣化。在内部导体24也为铝材料的情况下，一些应用场合可能需要在连接界面14的内部触点/内部导体处的非铝材料连接点。例如如图14所示，例如由金属（诸如黄铜或其他所需的金属）形成的中央帽50可以也通过激光或摩擦焊接应用于内部导体24的端部。为了施加中央帽50，磨削内部导体24的端部，以提供与中央帽50的选定槽形状相对应的销。为了容许在焊接附接过程中材料相互流动，中央帽50的槽形状和/或内部导体24的端部可以形成为提供环形材料间隙22。
激光焊接装置可以设置有光纤激光头扩展件，可以调整所述光纤激光头扩展件以使得激光束B瞄准沿着接缝16的每个目标位置。替代地，可以操纵其上有目标位置的同轴连接器2以将目标位置与激光头54对齐。激光头54通常包括瞄准仪56和聚焦透镜58，所述聚焦透镜58将激光束B聚焦于在目标位置处的焦点F上。如图15中所示，激光束B长度在到达焦点F之前需要有间隙，在示范性实施例中这通过面向接缝16的方向的连接器端部18得到满足。
在越过焦点F之前和越过焦点F时，激光束B具有增加的直径，从而逐步地降低激光束在除焦点F之外的纵向位置处的有效功率。为了最大化用于焊接的热产生量，激光头54可以相对于接缝16定位成使得焦点F在接缝16的外表面下方，例如在图16中所示。因此，当在接缝16内形成而非仅沿接缝16的最外表面形成孔洞侧壁20和外部导体8的外径的熔化区域时，获得最高功率水平，从而实现具有更大深度和强度的焊接件。
在其他实施例中，例如在图17和18中所示，孔洞6可以设置有邻近连接器端部18的向内突出的止动肩部52，外部导体8抵靠所述向内突出的止动肩部52以形成在外部导体8和止动肩部52之间的面向向内的圆周接缝16。接缝16设置为基本上垂直于同轴连接器2的纵向轴线。如图19和20中所示，激光束B到达接缝16而无来自内部导体24干涉的能力为同轴线缆尺寸和在接缝16所位于的孔洞6内距连接界面14的距离的函数。
除了调整激光束来跟随接缝16的内部圆周的增加的需求之外，本发明还需要移除额外的介电材料26，这可能产生电阻中断问题，能够通过增加其他的电阻调节特征（诸如介电垫片等）解决所述电阻中断问题。
本领域的技术人员将理解的是，所公开的连接器和互连方法具有显著的材料成本效率并且提供具有减少的尺寸和/或重量需求的永久密封的互连。
