Description

套管及屏蔽端子的制造方法
技术领域
本发明涉及套管及屏蔽端子的制造方法。
背景技术
在同轴电缆(屏蔽电线)的末端部连接有屏蔽端子，该屏蔽端子具有屏蔽功能。在专利文献1中公开了屏蔽端子具备的套管。套管插入到屏蔽端子的末端部的编织件与其内侧的绝缘体(绝缘部)之间。
套管呈圆筒状，在沿周向隔开间隔的三个部位设置有突起。绝缘部的周向的三点由各突起支承。
套管与编织件一起由筒压接。在专利文献1中记载了如下主旨：通过各突起而在绝缘部与套管之间形成空气层，补充由筒的压接作业引起的阻抗的降低。

专利文献1：日本特开2010-232046号公报
发明内容
发明要解决的课题
在专利文献1的情况下，在筒压接时及压接后也可维持各突起的突起形状。因此，在筒压接时，各突起的顶端部较强地陷入到绝缘部，有可能绝缘部的一部分被切断等而被压扁。
与此相对，在呈全长为相同直径的圆筒状的通用套管中，有时不能充分确保弯曲刚性，在筒压接时，套管自身较大地被压扁，有时使绝缘部过度压缩。
本发明是基于如上述的情况而完成的，以提供能够防止屏蔽电线的绝缘部被过度压缩的套管及具备该套管的屏蔽端子为课题。
用于解决课题的方案
本发明的第1方面是配置于屏蔽电线的绝缘部与屏蔽部之间、并能够由筒部按压的圆筒状的套管，其特征在于，所述套管在轴方向的中途遍及全周设置有向径向外侧鼓出的形状的凸部。
另外，本发明的第2方面是屏蔽端子的制造方法，其特征在于，将圆筒状的套管配置于屏蔽电线的绝缘部与屏蔽部之间，将筒部以将所述屏蔽部夹在中间的方式向所述套管侧按压，用所述筒部将在所述套管的轴方向的中途遍及全周向径向外侧鼓出的形状的凸部压扁而使该凸部伸长，使外导体端子与所述屏蔽电线连接。
发明效果
根据本发明的第1及第2方面，因为在套管的轴方向的中途遍及全周设置有向径向外侧鼓出的形状的凸部，所以能够将套管的弯曲刚性(反作用力)提高。由此，套管在筒部按压时不易被压扁，能够防止绝缘部被套管过度压缩。尤其是，因为凸部在套管遍及全周地设置，所以能够对绝缘部在周向上赋予均匀的压缩力，能够防止凸部陷入到绝缘部的周向的一部分。
根据本发明的第2方面，凸部由筒部压扁而伸长，因此能够良好地防止绝缘部被凸部过度地压缩。
附图说明

图2是套管的侧视图。
图3是示出在屏蔽电线的末端部将套管配置于绝缘部与屏蔽部之间的状态的剖视图。
图4是图3的主要部分放大图。
图5是与屏蔽电线的末端部连接的屏蔽端子的立体图。
图6是与屏蔽电线的末端部连接的屏蔽端子的剖视图。
具体实施方式
以下示出本发明的优选方式。
(1)在所述套管中优选的是，在所述凸部的径向外侧的端部、且在能够由所述筒部按压的部位设置有沿着所述轴方向的支承台部。据此，能够在筒部按压前在支承台部的内表面与绝缘部侧之间形成沿着轴方向的间隙，能够更确实地防止绝缘部过度被压缩。
(2)所述套管优选在轴方向的端部遍及全周设置有向径向外侧鼓出的形状的端侧凸部，所述端侧凸部在轴方向上在与所述凸部之间形成有凹部。据此，因为在套管的轴方向的端部侧连续地设置有由端侧凸部、凹部及凸部形成的凹凸形状，所以能够将套管的弯曲刚性更加提高，能够进一步确实地防止绝缘部被过度压缩。
(3)在所述屏蔽端子的制造方法中优选的是，按压所述凸部的所述筒部是与所述屏蔽部接触的线筒。据此，能够充分地享有如下本发明的优点：将套管的弯曲刚性提高，防止绝缘部被过度压缩。
<实施例1>
通过图1～图6说明本发明的实施例1。在具有屏蔽功能的屏蔽端子10中具备本实施例1的套管11，套管11与屏蔽电线60的末端部连接。
<屏蔽电线60>
屏蔽电线60是同轴电缆，如图3及图4所示，具备传递高频信号的由导体构成的芯线部61、和将芯线部61的周围包围的屏蔽部62。具体地讲，屏蔽电线60具备：芯线部61；绝缘树脂性的绝缘部63，其将芯线部61的外周覆盖；由编织件构成的屏蔽部62，其将绝缘部63的外周覆盖；以及绝缘树脂性的护套64，其将屏蔽部62的外周覆盖。在本实施例1的情况下，在绝缘部63与屏蔽部62之间设置有铜箔等金属箔65的层。铜箔等金属箔65的层起到将传送路径的阻抗调整成规定值的作用。
在屏蔽电线60的末端部，护套64在预定范围被除去，屏蔽部62的末端部露出，进一步地，通过屏蔽部62、绝缘部63以及金属箔65在预定范围被除去，从而芯线部61的末端部露出。
<屏蔽端子10>
如图6所示，屏蔽端子10除了套管11之外，还具备：内导体端子12；外导体端子13，其将内导体端子12的周围包围；以及介电体14，其介于外导体端子13与内导体端子12之间。套管11、内导体端子12以及外导体端子13均为金属制，介电体14为合成树脂制。
内导体端子12通过对导电性的金属板进行弯曲加工等而一体成形，在图示左侧的前部具有能够与未图示的对方侧内导体端子连接的对方侧连接部15，在图示右侧的后部具有开放筒状的电线侧连接部16，电线侧连接部16与芯线部61压接连接。对方侧连接部15具有在前后方向细长的筒状部分，在内部被插入连接对方侧内导体端子的突片。
介电体14具有在前后方向延伸并在后表面开口的收纳部17。在收纳部17从后方被插入内导体端子12。内导体端子12以使对方侧连接部15收纳于收纳部17、并使电线侧连接部16从介电体14的后表面向后方突出的状态装入到介电体14。
外导体端子13通过对导电性的金属板进行弯曲加工等而一体成形，如图5所示，具有圆筒状的嵌合部21、位于比嵌合部21靠后方的线筒18、位于比线筒18靠后方的绝缘筒19、以及将嵌合部21和线筒18连接的连结部24。通过线筒18和绝缘筒19构成筒部。
嵌合部21在内部收纳介电体14。在嵌合部21的内表面与介电体14之间形成有向前方开放的嵌合空间22。在嵌合空间22中嵌合未图示的对方侧外导体端子。对方侧外导体端子在嵌合空间22内与设置于嵌合部21的连接部23能导通地接触。
连结部24具有左右一对侧壁25。各侧壁25的前端与嵌合部21连结为一体，各侧壁25的后端与线筒18连结为一体。在各侧壁25的上端，在左右各自突出设置有突出部26。详细未说明，但是各突出部26在屏蔽端子10插入到未图示的连接器壳体时起到引导屏蔽端子10的插入动作、且限制屏蔽端子10从连接器壳体脱落的作用。
如图6所示，外导体端子13在各侧壁25之间具有在上下方向贯穿的空间部27。在空间部27配置有内导体端子12的电线侧连接部16。电线侧连接部16相对于芯线部61的压接作业能够通过从上下两侧进入到空间部27的治具(卷边器、砧座)而进行。
线筒18与屏蔽电线60的屏蔽部62压接连接。线筒18呈开放筒状，具有从底部28的左右两侧立起的一对线筒片31。各线筒片31被卷到屏蔽部62的外周。
绝缘筒19比线筒18大一圈，与屏蔽电线60的护套64压接连接。绝缘筒19呈开放筒状，具有从底部28的左右两侧立起的一对绝缘筒片32。各绝缘筒片32被卷到护套64的外周。
<套管11>
套管11为金属制，在整体上呈圆筒状，如图3及图4所示，夹插在金属箔65(绝缘部63侧)与屏蔽部62之间。套管11具有至少超出筒部(线筒18及绝缘筒19)的前后长度的前后长度。如图6所示，套管11在前部具有由线筒18按压的前侧被按压区域33，在后部具有由绝缘筒19按压的后侧被按压区域34。
套管11通过将在展开状态下为大致矩形的平板卷起而形成为圆筒形状。如图1所示，在套管11上沿着前后方向(轴方向)设置有周向两端的对接缘35。套管11能够以使对接缘35对接的状态维持圆筒形状。
套管11在前后方向中途的前侧被按压区域33具有遍及全周向径向外侧鼓出的形状的凸部36。如图4所示，凸部36的侧视方向的截面形状呈扁平台状，凸部36在成为径向外侧的突出方向的端部具有沿着前后方向的支承台部37。支承台部37的内径及外径在前后方向固定且比在前后方向邻接的部位的内径及外径大。支承台部37是受到线筒18的按压力(压缩力)的部分，与线筒18对置地配置。支承台部37具有比线筒18的前后长度小的前后长度。
套管11在比前侧被按压区域33靠前方的前端部具有遍及全周向径向外侧鼓出的形状的端侧凸部38。端侧凸部38在突出方向的端部具有沿着前后方向的外周部39。外周部39具有与支承台部37的内径及外径大致相同的内径及外径。外周部39具有比支承台部37的前后长度小的前后长度。外周部39面向套管11的前端部。对接缘35在外周部39处朝向套管11的前端部开放。
套管11在前侧被按压区域33的前端部且在端侧凸部38与凸部36之间形成有凹部41。如图4所示，凹部41的前端部及后端部通过由凸部36的前端部和端侧凸部38的后端部划定，从而成为朝向径向内侧呈锥形缩径的形状。凹部41的里部43(底面部)沿着前后方向配置，具有与套管11中的除了凸部36及端侧凸部38之外的部分的内径及外径相同的内径及外径。另外，凸部36及端侧凸部38通过在套管11的弯曲加工之前对展开状态的大致矩形的平板实施冲压加工而与凹部41一起形成。
接着，对套管的安装结构进行说明。
套管11从前方插入到屏蔽电线60中的屏蔽部62与金属箔65(绝缘部63侧)之间。如图3所示，套管11中包括前侧被按压区域33的前部配置于比护套64靠前方，包括后侧被按压区域34的后部以插入到护套64的内侧的状态配置。如图4所示，在凸部36的支承台部37与金属箔65之间及端侧凸部38的外周部39与金属箔65之间沿着前后方向形成有固定间隔的间隙20。
屏蔽电线60以组装有套管11的状态设置于外导体端子13的筒部上。线筒18与套管11的前侧被按压区域33对置地配置，绝缘筒19与套管11的后侧被按压区域34对置地配置。在该状态下，未图示的治具(卷边器、砧座)抵靠在线筒18及绝缘筒19，对其赋予向径向内侧的按压力。套管11的前侧被按压区域33隔着屏蔽部62由线筒18按压，套管11的后侧被按压区域34隔着屏蔽部62及护套64由绝缘筒19按压。
凸部36在线筒18的按压力超出预定值时成为与凹部41及端侧凸部38一起被压扁而向前方大致伸长的状态。由此，在凸部36的支承台部37与金属箔65之间及端侧凸部38的外周部39与金属箔65之间形成的间隙20基本上消失(参照图6)。
套管11的前侧被按压区域33通过与凸部36、凹部41及端侧凸部38连续的凹凸形状而被提高弯曲刚性，成为比后侧被按压区域34难压扁的结构。因此，即使凸部36等被压扁，套管11的前侧被按压区域33也不会进一步更大地被压扁，能够防止绝缘部63由套管11按压而被过度压缩。
线筒18在由套管11支承的状态下与屏蔽部62压接连接。相同地，绝缘筒19在由套管11支承的状态下与护套64压接连接。在本实施例1的情况下，能够同时进行线筒18、绝缘筒19以及电线侧连接部16各自的压接作业。由此，如图6所示，屏蔽端子10与屏蔽电线60的末端部连接。
如上所述，根据本实施例1，因为在套管11的前后方向中途的前侧被按压区域33遍及全周设置有向径向外侧鼓出的形状的凸部36，所以能够将套管11的弯曲刚性(反作用力)提高，能够防止绝缘部63被套管11过度压缩。尤其是，因为凸部36在套管11上遍及全周地设置，所以能够对绝缘部63在周向上赋予均匀的压缩力。而且，因为凸部36被线筒18压扁而伸长，所以能够良好地防止绝缘部63被凸部36过度压缩。
另外，因为在凸部36的突出方向的端部设置有沿着前后方向的支承台部37，所以能够在线筒18按压前在支承台部37的内表面与绝缘部63侧之间形成沿着轴方向的间隙20，能够更确实地防止绝缘部63被过度压缩。
而且，在套管11从前端部依次连续地设置有端侧凸部38、凹部41以及凸部36，所以前侧被按压区域33成为更进一步不易被压扁的结构，能够更进一步确实地防止绝缘部63被过度压缩。
<其他实施例>
本发明并不限定于通过上述记述及附图说明的实施例，例如下面的方式也包含于本发明的技术范围。
(1)凸部、端侧凸部以及凹部也可以在套管的弯曲加工后通过模锻加工等而形成。
(2)套管的对接缘也可以通过焊接、粘接件等接合方式而接合为一体。另外，套管也可以最初就加工成无接头圆筒状。
(3)凸部也可以在套管的前后方向中途形成有多个。
(4)套管也可以在能够由绝缘筒按压的部位遍及全周设置有向径向外侧鼓出的形状的凸部。
(5)套管也可以是不被绝缘筒按压的结构。另外，也能够从筒部将绝缘筒省略。
(6)也能够从套管将端侧凸部省略。

所述凸部形成为：所述筒部的按压力超出预定值时，以使在所述支承台部与所述绝缘部之间以及所述端侧凸部与所述绝缘部之间形成的间隙消失的方式，与所述凹部及所述端侧凸部一起被压扁而沿着轴向延伸，
在所述屏蔽端子的制造方法中，
将所述套管配置于所述屏蔽电线的绝缘部与所述屏蔽部之间，
将所述筒部以将所述屏蔽部夹在中间的方式向所述套管侧按压，
用所述筒部将在所述套管的轴方向的中途遍及全周向径向外侧鼓出的形状的所述凸部以与所述绝缘部之间形成的间隙消失的方式压扁而使该凸部伸长，使外导体端子与所述屏蔽电线连接。
3.根据权利要求2所述的屏蔽端子的制造方法，其中，按压所述凸部的所述筒部是与所述屏蔽部接触的线筒。
