导电部件
技术领域
本发明涉及一种导电部件。
背景技术
在专利文献1中示出在电动汽车、混合动力汽车等车辆中作为在电池、电动机、逆变器装置等机器间布线的手段的导电部件，其具备：管，其具有形状保持性；以及包覆电线，其具有可挠性。作为将管和包覆电线的芯线连接的手段，采用如下方法：将芯线的端部插入到管的端部内，将管和芯线的端部压扁成扁平状。

发明内容
发明所要解决的课题
在上述连接方法中，在管、芯线是铝制的情况下，不能充分去除表面的氧化皮膜。特别是，在芯线通过由多个铝制的线材制成的捻合线构成的情况下，几乎不能去除氧化皮膜。在氧化皮膜没有被去除的状态下，管与芯线之间的接触阻力变高，从而在接触信赖性这点上存在问题。
本发明是基于上述事情完成的，其目的在于实现接触信赖性的提高。
用于解决课题的手段
本实施例的导电部件，其特征在于，具备：
柔软导体，其由多个线材捆扎而成且具有可挠性；
刚性导体，其具有形状保持性；
固装部，其形成于所述刚性导体的端部，所述固装部将所述柔软导体包围且被固装于所述柔软导体；以及
滑接部，其形成为从所述固装部的内周突出的形态，所述滑接部能与所述线材滑接。
发明效果
在处于将固装部固装到柔软导体之前的状态下，若将柔软导入插入到该固装部，则一部分线材的氧化皮膜通过与固装部的内周面滑接而被去除，并且其他的线材的氧化皮膜通过与滑接部的滑接而被去除。氧化皮膜在将柔软导体插入到固装部的工序以及将柔软导体固装于固装部的工序中的至少一个工序被去除。因为通过设置滑接部，从而使得氧化皮膜被去除的线材的数量增加，所以在柔软导体与刚性导体之间，接触阻力降低，接触信赖性提高。

具体实施方式
本发明的导电部件也可以构成为：所述刚性导体具备筒状主体和筒状末端部件，所述筒状主体构成所述刚性导体中的除了所述固装部以外的大致全长的区域，所述筒状末端部件配设于所述刚性导体的端部且构成所述固装部。根据此结构，能使刚性导体中形成滑接部的部位只限定于供柔软导体插入的固装部。由此，能实现刚性导体的轻量化和材料成本的降低。
本发明的导电部件也可以构成为：多个所述滑接部的突出端部彼此相连。根据此结构，因为能将滑接部的突出长度最大限度地确保为较长，所以能增加与滑接部滑接的线材的数量。
本发明的导电部件也可以构成为：所述滑接部形成为折弯的形状。根据此结构，因为当使固装部塑性变形而被固装于柔软导体时，滑接部容易变形，所以固装后的固装部的形状稳定。
本发明的导电部件也可以构成为：所述刚性导体沿全长形成为筒状，从所述刚性导体的内周沿全长形成有所述滑接部。根据此结构，能只通过挤压成形而将包含滑接部在内的整个刚性导体作为一体部件进行制造。
＜实施例1＞
以下，参照图1至图3对将本发明具体化的实施例1进行说明。本实施例1的导电部件A在电动汽车、混合动力汽车等车辆中作为在电池、电动机、逆变器装置等机器(图示省略)间进行布线的手段使用。导电部件A构成为具备刚性导体10以及具有可挠性的包覆导体20。
刚性导体10由铝或者铝合金制的管构成，刚性导体10具有基于这自身的刚性而不易变形的形状保持性。刚性导体10被弯曲加工成预定的形状，并沿车辆的地板下面布线。刚性导体10构成为具备筒状主体11和一对筒状末端部件12，筒状主体11沿全长形成为截面呈圆形，一对筒状末端部件12被固装于筒状主体11的前后两端部。筒状主体11是构成刚性导体10中的除了两端部以外的大部分的区域的较长的部件。筒状主体11的内周的截面形状是大致正圆形，在筒状主体11的内周没有形成突起状部位等。
筒状末端部件12具有作为与包覆导体20连接的连接手段、即固装部13的功能。筒状末端部件12是具有筒状的主体部14以及从主体部14的内周向径向内侧突出的四个滑接部15的单个部件。如图3所示，处于将包覆导体20(柔软导体21)与刚性导体10(固装部13)连接之前的状态的主体部14形成为其外径以及内径的尺寸与筒状主体11相同的圆筒形。
通过利用激光焊接等将主体部14的端面与筒状主体11的端面以同轴状接合，从而筒状末端部件12和筒状主体11成为一体化。当将刚性导体10和包覆导体20连接时，主体部14通过敛紧加工而塑性变形成大致正六角形(正多角形)(参照图2)。
在主体部14处于没有被敛紧加工的状态(刚性导体10与包覆导体20未连接的状态)下，四个滑接部15沿主体部14的圆周方向隔开等角度间隔配设。并且，在本实施例1中，将滑接部15的数量设定为四个，但是滑接部15的数量也可以是三个以下，也可以是五个以上。在刚性导体10的以与其轴线成直角的方式被切断时的截面中，各滑接部15形成为向主体部14的中心沿径向以直线状延伸的形状。
各滑接部15呈壁状，沿主体部14(筒状末端部件12)的全长连续形成。四个滑接部15的突出端部彼此以在主体部14的中心部相互形成为十字形的方式相连。因此，在刚性导体10与包覆导体20处于未连接的状态下，筒状末端部件12(固装部13)的中空内部被分隔成四个四分之一圆弧形的连接空间16。
包覆导体20构成为具备由多个线材22捻合而成的柔软导体21(芯线)以及沿整个周向包围柔软导体21的绝缘包覆部23。线材22(柔软导体21)由铝或者铝合金制成。即、包覆导体20的柔软导体21与刚性导体10是相同材料。在包覆导体20中的与刚性导体10(固装部13)连接的端部，绝缘包覆部23被去除而露出柔软导体21。
当将包覆导体20与刚性导体10连接时，首先，在包覆导体20的端部将绝缘包覆部23去除，从而使柔软导体21露出。接着，解除柔软导体21中的露出部分的线材22的捻合，使线材22处于以大致笔直的方式被捆扎的状态。接着，将柔软导体21分割成四份，将被分割的柔软导体21(线材22的束)分别单独地插入到固装部13(筒状末端部件12)的四个连接空间16。
在插入的过程中，线材22与连接空间16的内壁面滑接。即、线材22与主体部14的内周面滑接，并且线材22与滑接部15滑接。通过该滑接，从而使得线材22的表面的氧化皮膜(图示省略)被刮除，主体部14的内周面的氧化皮膜(图示省略)被刮除，滑接部15的表面的氧化皮膜(图示省略)被刮除。像这样，在线材22与筒状末端部件12的氧化皮膜被去除之后，使主体部14以从圆形成为正六角形的方式塑性变形。
此时，因为主体部14减径变形，所以连接空间16的容积(截面积)变小，主体部14和滑接部15以沿径向以及圆周方向压缩的方式与线材22的束密合，从而柔软导体21与固装部13(刚性导体10)被固装在一起。与上述的插入工序相同，就算在固装工序中，线材22的表面的氧化皮膜、主体部14的内周面的氧化皮膜以及滑接部15的表面的氧化皮膜被刮除。由此，包覆导体20的柔软导体21和刚性导体10连接成能导通且脱离被限制的状态。
本实施例1的导电部件A具备包覆导体20和刚性导体10，包覆导体20通过由多个线材22捆扎而成的柔软导体21和将柔软导体21包围的绝缘包覆部23一体化而形成且具有可挠性，刚性导体10具有形状保持性。在刚性导体10的端部形成有固装部13，固装部13将柔软导体21包围且能导通地被固装于柔软导体21。并且，刚性导体10形成为从固装部13的内周突出的形态，刚性导体10具备能与线材22滑接的滑接部15。
若柔软导体21插入到处于被固装到柔软导体21之前的状态的固装部13，则一部分的线材22因与固装部13的内周面滑接而被去除氧化皮膜，另一部分的线材22因与滑接部15滑接而被去除氧化皮膜。因为通过设置滑接部15而使得被去除氧化皮膜的线材22的数量增加，所以在柔软导体21与刚性导体10之间，接触阻力降低，接触信赖性提高。
另外，刚性导体10具备筒状主体11和筒状末端部件12，筒状主体11构成刚性导体10中的除了固装部13以外的大致全长的区域，筒状末端部件12配设于刚性导体10的端部而构成固装部13。通过采用这样的构成，刚性导体10中的形成滑接部15的部分能仅限定为供柔软导体21插入的固装部13。由此，实现了刚性导体10的轻量化和材料成本的降低。
另外，因为4个(多个)滑接部15的突出端部彼此相连，所以能将滑接部15的突出长度最大限度地确保为较长。由此，能增加与滑接部15滑接的线材22的数量。
＜实施例2＞
接着，参照图4对将本发明具体化的实施例2进行说明。本实施例2的导电部件B采用了构成刚性导体30的筒状末端部件31(固装部32)的滑接部34的形状与上述实施例1不同的构成。因为其他构成与上述实施例1相同，所以对相同的构成赋予相同符号，省略结构、作用以及效果的说明。
本实施例2的筒状末端部件31是具有筒状的主体部33以及从主体部33的内周向径向内侧突出的四个滑接部34的单个部件。处于将包覆导体20与刚性导体30连接之前的状态的主体部33形成为其外径以及内径的尺寸与筒状主体相同的圆筒形。通过利用激光焊接等将主体部33的端面与筒状主体的端面以同轴状接合，从而筒状末端部件31和筒状主体形成为一体。在将刚性导体30和包覆导体20连接的工序中，主体部33通过敛紧加工而塑性变形成大致正六角形(正多角形)。
在主体部33处于没有被敛紧加工的状态(刚性导体30与包覆导体20未连接的状态)下，四个滑接部34以沿主体部33的圆周方向隔开等角度间隔的方式配设。并且，在本实施例2中，将滑接部34的数量设定为四个，但是滑接部34的数量也可以是三个以下，也可以是五个以上。各滑接部34形成为折弯的壁状，沿主体部33(筒状末端部件31)的全长连续形成。
在刚性导体30的以与其轴线成直角的方式切断时的截面中，各滑接部34形成为折弯成钝角状的形状(图示省略)。即、一个滑接部34由周缘侧壁部35和中心侧壁部36构成，周缘侧壁部35从主体部33的内周相对于径向倾斜地突出，中心侧壁部36从周缘侧壁部的突出端缘向主体部33的中心突出。周缘侧壁部35与中心侧壁部36倾斜地相连。
另外，四个滑接部34在主体部33的中心部彼此相连。即，四个中心侧壁部36的突出端部彼此以形成为十字形的方式相连。由此，筒状末端部件31(固装部32)的中空内部被分隔为四个连接空间37。若将线材22的束插入到各连接空间37，则通过线材22分别与周缘侧壁部35和中心侧壁部36滑接，从而线材22、主体部33以及滑接部34的氧化皮膜(图示省略)被刮除。
在将包覆导体20的柔软导体21和刚性导体30连接的工序中，若将主体部33以从圆形成为正六角形的方式塑性变形，则各滑接部34以使周缘侧壁部35与中心侧壁部36所形成的角度减小的方式折弯变形。相应地，因为各连接空间37的容积减小，所以主体部33和滑接部34以沿径向以及圆周方向压缩的方式与线材22的束密合。由此，包覆导体20的柔软导体21和刚性导体30连接成能导通且脱离被限制的状态。
在本实施例2的导电部件B中，因为4个(多个)滑接部34的突出端部彼此相连，所以能将滑接部34的突出长度最大限度地确保为较长。并且，因为滑接部34形成为折弯的形状，所以能增加与滑接部34滑接的线材22的数量。另外，通过相互相连的四个滑接部34形成为折弯的形状，从而当使固装部32塑性变形而与柔软导体21接合时，滑接部34变得容易变形。因此，固装后的固装部32(筒状末端部件31)的形状稳定。
＜实施例3＞
接着，参照图5对将本发明具体化的实施例3进行说明。本实施例3的导电部件C采用了构成刚性导体40的筒状末端部件41(固装部42)的滑接部44的形状与上述实施例1不同的构成。因为其他构成与上述实施例1相同，所以对相同构成赋予相同符号，省略结构、作用以及效果的说明。
本实施例3的筒状末端部件41(固装部42)具备主体部43和多个(例如八个)滑接部44，主体部43在刚性导体40和包覆导体20未连接的状态下形成为圆形，多个(例如八个)滑接部44以从主体部43的内周沿圆周方向隔开等角度的间隔的方式配置。各滑接部44形成为从主体部43的内周向中心朝径向内侧以直线状地突出的壁状。
滑接部44的突出长度设定为尺寸比处于圆形状态的主体部43的半径小。沿圆周方向相邻的滑接部44彼此的间隔设定为尺寸比一个线材22的外径大。因此，在相邻的滑接部44之间收纳多个线材22。另外，就算在刚性导体40和包覆导体20连接且主体部43塑性变形成正六角形的状态下，滑接部44的突出端彼此保持为非接触的状态。
＜实施例4＞
接着，参照图6对将本发明具体化的实施例4进行说明。本实施例4的导电部件D采用了构成刚性导体50的筒状末端部件51(固装部52)的滑接部54的形状与上述实施例1不同的构成。因为其他构成与上述实施例1相同，所以对相同的构成赋予相同符号，省略结构、作用以及效果的说明。
本实施例4的筒状末端部件51(固装部52)具备主体部53和多个(例如12个)滑接部54，主体部53在处于刚性导体50和包覆导体20未连接的状态下形成为圆形，多个(例如12个)滑接部54以从主体部53的内周沿圆周方向隔开等角度的间隔的方式配置。各滑接部54形成为从主体部53的内周向径向内侧突出的肋状。
即，各滑接部54的向径向突出的突出尺寸和沿圆周方向相邻的滑接部54彼此的间隔设定为尺寸大致相同。另外，滑接部54的突出尺寸设定为尺寸与一个线材22的外径大致相同。即、收纳于相邻的滑接部54之间的线材22的数量只有一个或两个。因此，当将刚性导体50和包覆导体20连接时，能将柔软导体21以线材22被捻合在一起的状态(没有解除捻合的状态)插入到筒状末端部件51(固装部52)内。
＜其他实施例＞
本发明并非限定于根据上述记载以及附图所说明的实施例，例如以下的实施例也包含在本发明的技术的范围内。
(1)在上述实施例1～4中，刚性导体由筒状主体和筒状末端部件构成，但是也可以构成为刚性导体沿全长形成为筒状，且滑接部从刚性导体的内周沿全长突出形成。根据此结构，能通过挤压成形将包含滑接部在内的整个刚性导体作为一体部件进行制造。
(2)在上述实施例1～4中，滑接部一体形成于固装部(筒状末端部件)的内周，但是滑接部也可以是通过将相对于固装部作为分体的部件而成形的部件固装到固装部的内周。
(3)在上述实施例1～4中，刚性导体是铝制或者铝合金制，但是刚性导体的材料也可以是除了铝、铝合金以外的材料(铜、铜合金等)。
(4)在上述实施例1～4中，柔软导体是铝制或者铝合金制，但是柔软导体的材料也可以是除了铝、铝合金以外的材料(铜、铜合金等)。
(5)在上述实施例1～4中，将刚性导体和包覆导体的柔软导体采用相同的材料，但是刚性导体和柔软导体也可以采用不同的材料。
(6)在上述实施例1～4中，在沿圆周方向相邻的滑接部之间收纳有至少一边的线材，但不限于此，对主体部的内周实施滚花加工，多个滑接部也可以以在圆周方向比线材的外径小的间距排列。与实施例4相同，在这种情况下，能够不解开线材的捻合而将柔软导体插入到固装部内。
(7)在上述实施例1～4中，在将包覆导体(柔软导体)与刚性导体(固装部)连接之前的状态下，主体部与筒状主体的截面形状呈圆形，但是主体部与筒状主体的截面形状也可以呈非圆形。
(8)在上述实施例1～4中，将刚性导体采用中空的管状，但是刚性导体中的除了固装部(筒状末端部件)以外的区域也可以是实心的棒状。
(9)在上述实施例1～4中，在将柔软导体插入到固装部的工序和将柔软导体固装于固装部的工序的两工序中，氧化皮膜被去除，但是氧化皮膜的去除也可以只在插入工序和固装工序中的任意一方的工序中进行。
