具体实施方式
以下，使用附图对本发明的实施方式所涉及的线缆组件进行详细说明。
如图1所示，屏蔽连接器1用于高速传输，具备：线缆组件2，其与线缆10即屏蔽双绞线(STP，shield twisted pair)电线的末端连接；以及外壳3，其容纳该线缆组件2。即，屏蔽连接器1是差动通信用的高速传输连接器，具有电磁屏蔽结构。
如图1所示，外壳3由树脂形成为箱形，具有容纳线缆组件2的组件容纳部3a。在外壳3的上表面3b侧设有用于在与未图示的对方连接器嵌合时维持嵌合状态的锁定臂3c。
另外，如图1、图2所示，线缆组件2具备线缆10、金属制的阴端子(端子)15、套筒16、屏蔽端子17、内壳18、阻抗调整用的匹配部件19作为构成部件。
如图2、图4、图7所示，线缆10具备：绞合的2根内部电线11、11；金属制的编织层13，其经由屏蔽箔12覆盖2根内部电线11、11；以及护套14，其是树脂制的外部覆皮，覆盖该编织层13。各内部电线11具有金属制的芯线11a和将该芯线11a覆盖的树脂制的绝缘覆皮11b。而且，在线缆10的末端10a侧露出的2根内部电线11、11被解开，阴端子15的一对芯线压接片15b、15b通过紧固加工而压接连接于从该各绝缘覆皮11b露出的芯线11a。另外，阴端子15在一对芯线压接片15b、15b的前侧具有与未图示的对方连接器的阳端子的突片电连接的接触部15a。另外，在图2和图4所示的阴端子15中，示出了一对芯线压接片15b、15b被紧固后的形状。
如图2、图4所示，套筒16为金属制，且紧固前的形状为C字板状，套筒16安装于线缆10的护套14的一部分被切除而露出的编织层13的外周。C字板状的套筒16在中央具有多个凸部16a，在一端侧具有卡合凹部16b，在另一端侧具有卡合凸部16c。而且，如图6、图8所示，在将后述的屏蔽端子17的编织层压接片17b紧固于线缆10的折返后的编织层13A后，该折返后的编织层13A配置于从编织层压接片17b内的前侧到与护套压接片17c的前端缘17d邻接的位置。即，如图4、图7所示，在C字板状的套筒16通过被圆筒状紧固而配置在编织层13的外周上并且卡合凸部16c嵌入到卡合凹部16b的状态下，该套筒16被折返后的编织层13A覆盖。即，如图6～图8所示，编织层13在被紧固为圆筒状的套筒16的前端部16d处经由折返部13a向后端缘16e侧折返，在折返部13a折返后的编织层13A将圆筒状的套筒16的外周覆盖。
如图2所示，屏蔽端子17通过使用钣金材料的钣金加工而形成。并且，屏蔽端子17具有用来容纳内壳18和匹配部件19的充当屏蔽连接部的筒状的壳体容纳部17a。另外，屏蔽端子17具有：一对编织层压接片17b、17b，其对将线缆10的一部分护套14切除而露出的编织层13进行紧固连接；以及一对护套压接片17c、17c，其对线缆10的护套14紧固连接。如图6所示，屏蔽端子17的编织层压接片17b将已紧固于护套14露出的编织层13的外周上的套筒16紧固，并且将覆盖该套筒16的外周且在折返部13a折返后的编织层13A也紧固连接。即，编织层压接片17b隔着在折返部13a折返后的编织层13A而紧固于套筒16的外周。并且，在折返部13a折返后的编织层13A成为被套筒16和编织层压接片17b夹持的状态，屏蔽端子17和编织层13电连接。
对线缆10与屏蔽端子17的紧固压接连接进行详述，如图6～图8所示，在线缆10的护套14的外周紧固有屏蔽端子17的护套压接片17c。另外，通过将编织层压接片17b隔着在折返部13a折返后的编织层13A而紧固于套筒16，且进一步地将护套压接片17c紧固于护套14，从而线缆10相对于屏蔽端子17被保持(固定)。在该情况下，如图6、图8所示，套筒16的后端缘16e与护套压接片17c的前端缘17d相邻。即，在套筒16的后端缘16e与护套压接片17c的前端缘17d之间，在轴向上存在一些间隙t。另外，在图2所示的屏蔽端子17中，示出了一对编织层压接片17b、17b以及一对护套压接片17c、17c被紧固后的形状。
如图2、图3、图6所示，内壳18由合成树脂形成为椭圆柱状，在其两侧具有供与线缆10的末端连接的阴端子15插入的左右一对端子容纳室18a、18a。容纳在该各端子容纳室18a内的阴端子15被未图示的卡定机构保持。另外，在内壳18的上表面18b和下表面18c的后侧的中央分别形成有供后述的树脂制的匹配部件19的一对卡合突起19b、19b压入的卡合槽(卡合凹部)18d。
如图6、图7所示，匹配部件19是阻抗调整用的电介质，夹装在内壳18与套筒16之间，以抑制阻抗失配并提高屏蔽连接器1的线缆组件2的传送性能。如图2、图3所示，阻抗调整用的匹配部件19形成为树脂制的筒状，具有供压接连接于2个阴端子15、15的内部电线11、11的绞合解开的部分插通的一对插通孔19a、19a。进一步地，匹配部件19在上下部分的中央的前方分别突出设置有向内壳18的上下的卡合槽18d、18d压入的卡合突起(卡合部)19b。这些卡合槽18d和卡合突起19b构成使内壳18和匹配部件19一体化的卡合机构。并且，如图7所示，在屏蔽端子17的筒状的壳体容纳部17a内容纳已一体化的内壳18和匹配部件19，并且通过由卡定片部17e和卡定凹部19d构成的卡定机构来保持。另外，也可以使用作为导电体的金属性的部件来代替作为电介质的匹配部件19。
接着，对构成上述线缆组件2的各构成部件的组装顺序进行说明。
首先，将线缆10的末端10a的一部分护套14切除而使编织层13露出，并将套筒16以圆筒状紧固于该露出的编织层13的外周。然后，如图4所示，以在编织层13的折返部13a折返后的编织层13A覆盖圆筒状的套筒16的外周的方式，将编织层13的端部向后端缘16e侧折返。
接着，通过紧固加工将阴端子15的芯线压接片15b压接连接于在线缆10的末端10a侧露出的2根内部电线11、11的从各绝缘覆皮11b露出的芯线11a。之后，将2个阴端子15、15插入到阻抗调整用的匹配部件19的一对插通孔19a、19a中，并容纳在内壳18的一对端子容纳室18a、18a中。
然后，将匹配部件19的卡合突起19b压入并保持于内壳18的卡合槽18d，将已与该匹配部件19一体化的内壳18容纳于屏蔽端子17的壳体容纳部17a。之后，通过将屏蔽端子17的编织层压接片17b紧固于线缆10的在编织层13的折返部13a折返后的编织层13A，且进一步地将护套压接片17c紧固在线缆10的护套14上，从而完成图1、图6所示的线缆组件2。
根据以上实施方式的线缆组件2，如图6所示，即使在使线缆10相对于屏蔽端子17分离的方向P上施加了拉伸力，也能够防止线缆10相对于屏蔽端子17的护套压接片17c相对分离。
详细而言，如图6所示，在运输线缆组件2等时或者作为高速传输连接器用的屏蔽连接器1搭载于车辆时等，有时在使线缆10相对于屏蔽端子17分离的方向P上施加拉伸力。在该情况下，通过使套筒16沿拉伸方向P移动，从而套筒16的后端缘16e与屏蔽端子17的护套压接片17c的前端缘17d抵接。该抵接是由于线缆10被拉伸，编织层13的折返部13a向拉伸方向P按压套筒16的后端部，套筒16向拉伸方向P位移从而产生的作用。编织层压接片17b经由折返后的编织层13A而被紧固于套筒16，另外，护套压接片17c紧固于护套14，从而线缆10相对于屏蔽端子17被紧固并确保了其保持力。因此，即使由于所述抵接而对线缆10施加拉伸力，也能够防止线缆10相对于屏蔽端子17相对分离(偏移)。因此，能够防止由偏移而引起的屏蔽端子17与线缆10的编织层13的电连接可靠性降低，提高电连接可靠性。并且，由于防止了偏移，因此还能够提高线缆组件2对线缆10的保持力。
这样，在线缆组件2中，在线缆10被施加了拉伸力时，套筒16的后端缘16e与屏蔽端子17的护套压接片17c的前端缘17d抵接，从而进一步确保线缆10的保持力。
另外，如图8所示，在护套压接片17c对护套14的紧固状态中，编织层13的在护套压接片17c的紧固部分中的内径B与编织层13的在未紧固的护套14的部分中的内径A相等。或者，以大致相等的方式，将护套压接片17c紧固于护套14的外周。即，以“编织层13的内径B＝编织层13的内径A或者编织层13的内径B≈编织层13的内径A”的方式，将护套压接片17c紧固于护套14的外周。并且，越提高护套压接片17c的紧固量，编织层13的内径B越小，保持力越高，但变成“编织层13的内径B＜编织层13的内径A”，导致在轴向上，缆线10的阻抗失配。然而，在线缆组件2中，由于“编织层13的内径B＝编织层13的内径A或者编织层13的内径B≈编织层13的内径A”，所以能够在确保线缆10的保持力的同时防止阻抗失配。
接着，对比较例进行说明。比较例所涉及的屏蔽双绞线(STP)连接器在STP电介质体内具备外导体(屏蔽端子)，该外导体利用筒部将包围STP线缆的绞合的一对电线并屏蔽的编织线等的屏蔽导体紧固并压接连接。
然而，在比较例的STP连接器中，在向使STP线缆相对于外导体相对分离的方向施加了拉伸力的情况下，编织线等的屏蔽导体相对于筒部偏移，或者在最差的情况下，屏蔽导体有可能从筒部脱离。因此，担心由于偏移等导致外导体与STP线缆中的编织线等的屏蔽导体的电连接可靠性降低。
以上，对本实施方式进行了说明，但本实施方式并不限于此，能够在本实施方式的主旨的范围内进行各种变形。
即，根据所述实施方式，套筒在紧固前的形状为C字板状，在紧固后成为圆筒状的形状，但也可以从紧固前开始为圆筒状等的筒状的形状。
