技术领域
本发明涉及线束。
背景技术
以往，例如车辆用的线束具备：多个电线束，由多条电线构成；和连接器，各电线束插通于该连接器，所述连接器装配于设备的箱体(例如专利文献1)。
在专利文献1记载的线束中具备屏蔽构件，该屏蔽构件由导电性的线材编织而成的编织线构成，通过将多个电线束包围而将电磁噪声屏蔽。

发明内容
发明要解决的课题
但是，在专利文献1记载的线束中，具有沿着线束的分支路径分支的多个分支部的屏蔽构件是必需的。但是，有如下问题：通过编织线材而形成这样的屏蔽构件在技术上困难，制造工序变得繁杂。
本发明的目的在于提供一种能够通过简单的结构适当地屏蔽分支路径的线束。
用于解决课题的方案
用于达成上述目的的线束具备：多个屏蔽导电路径，由包括多条电线的多个电线束及由导电性的线材编织成筒状而成的编织线构成，具有将所述电线束分别包围的多个屏蔽构件；和连接器，所述屏蔽导电路径各自插通于该连接器，所述连接器装配于设备的箱体，所述屏蔽构件各自具有：筒状的主体部，将该电线束包围；和分离部，从所述主体部中的比所述连接器靠该电线束的末端侧的部分与该电线束分离地延伸，多个所述分离部汇集为一个。
根据上述结构，多个屏蔽导电路径插通于连接器。另外，各屏蔽构件在比连接器靠电线束的末端侧、即箱体的内部具有从电线束分离地延伸的分离部。各个分离部汇集为一个。因此，能够抑制电线在装配连接器的设备的箱体的外部从屏蔽构件露出。另外，通过将各屏蔽构件的分离部固定于箱体的内部的预定部位，能够一并进行各屏蔽构件的接地。
在此，在箱体的内部，电线从屏蔽构件露出。但是，因为箱体自身具有屏蔽功能，所以可确保屏蔽性。这样，根据上述结构，能够在不使用具有分支部的屏蔽构件的情况下适当地屏蔽线束的分支路径。
在上述线束中，在所述分离部固定有端子构件。
根据上述结构，能够借助端子构件容易地将分离部固定于箱体的内部的预定部位。由此，能够容易进行各屏蔽构件的接地。
在上述线束中优选的是，所述分离部以预先成形的状态压接于所述端子构件。
根据上述结构，各屏蔽构件的分离部和端子构件的固定操作进一步变得容易。
在上述线束中优选的是，所述分离部设置于所述箱体的内部，汇集为一个的多个所述分离部在所述箱体的内部接地。
发明效果
根据本发明，能够通过简单的结构适当地屏蔽分支路径。

图4是将图3的屏蔽构件的分离部与敛紧前的状态的端子构件的筒部相互分开地示出的分解立体图。
具体实施方式
以下，参照图1及图2对线束的一实施方式进行说明。
如图1所示，线束10布设于例如混合动力车、电动汽车，将设备彼此电连接。
如图1及图2所示，线束10具备电磁噪声被屏蔽的多条(在本实施方式中为三条)屏蔽导电路径13和装配于设备91的箱体91a的连接器20。
从连接器20导出的屏蔽导电路径13被分支，分别与单独的设备(省略图示)连接。
<屏蔽导电路径13>
如图2所示，屏蔽导电路径13由电线束12和将电线束12包围的屏蔽构件40构成，电线束12由多条(在本实施方式中两条)电线11构成。
各电线11具有芯线(省略图示)和将芯线的外周覆盖的绝缘包覆部11b。各电线11是自身不具有屏蔽结构的非屏蔽电线。
芯线例如是将由铜合金构成的多根金属线材绞合而形成的绞线。在各电线11的芯线的末端固定有端子(省略图示)，该端子在箱体91a内与设备91的一个以上电气要素连接。
绝缘包覆部11b由电绝缘性的合成树脂材料构成，呈圆筒状。
屏蔽构件40由编织线构成，该编织线通过由铝合金等构成的导电性的线材编织成筒状而得到。
如图2所示，多个屏蔽导电路径13插通于连接器20。在比连接器20靠电线束12的末端侧、即箱体91a的内部，各电线束12通过构成对应的屏蔽构件40的侧壁的线材彼此的间隙而从对应的屏蔽构件40的内部露出到外部。另外，上述间隙通过将线材彼此的间隙展开而形成。
各屏蔽构件40具有：筒状的主体部41，将电线束12包围；和分离部42，在箱体91a的内部不包围电线束12，与电线束12分离地延伸。
<连接器20>
如图2所示，连接器20具有筒状部21和从筒状部21向外周侧突出的凸缘22。凸缘22设置于筒状部21中的轴线方向的中央部。在凸缘22设置有用于装配于箱体91a的装配孔(省略图示)。连接器20通过铝合金等金属材料形成。
<端子构件60>
如图2所示，在各屏蔽构件40的分离部42固定有被称为所谓的开放筒端子的端子构件60。端子构件60具有：基部61，具有螺孔(省略图示)；和筒部62，从基部61延伸。端子构件60由铝合金等导电性的金属材料构成。各屏蔽构件40的分离部42的端部分别以预先汇集成圆柱状的状态通过敛紧成圆筒状的筒部62压接于端子构件60。
各端子构件60通过将在基部61的螺孔中插通的螺钉63紧固于在金属制的箱体91a的内部设置的母线50，从而以相互重合的状态被固定。
因此，各屏蔽构件40的分离部42的端部通过各端子构件60而汇集为一个。
另外，优选以各筒部62相互不重合的方式配置各端子构件60。
接着，对本实施方式的作用效果进行说明。
(1)各屏蔽构件40具有：筒状的主体部41，将电线束12包围；和分离部42，在比连接器20靠电线束12的末端侧的部分、即箱体91a的内部与电线束12分离地延伸。各自分离部42汇集为一个。
根据这样的结构，多个屏蔽导电路径13插通于连接器20。另外，各屏蔽构件40在箱体91a的内部具有从电线束12分离地伸出的分离部42。多个分离部42汇集为一个。
因此，能够抑制电线11在装配连接器20的设备91的箱体91a的外部从屏蔽构件40露出。另外，通过将各屏蔽构件40的分离部42固定于箱体91a的内部的母线50，从而能够一并进行各屏蔽构件40的接地。
在此，在箱体91a的内部，电线11从屏蔽构件40露出。但是，因为箱体91a自身具有屏蔽功能，所以可确保屏蔽性。这样，根据上述结构，能够在不使用具有分支部的屏蔽构件的情况下适当地屏蔽线束10的分支路径。因此，能够通过简单的结构适当地屏蔽线束10的分支路径。
(2)在分离部42固定有端子构件60。
根据这样的结构，能够借助端子构件60将分离部42固定于箱体91a的内部的母线50。由此，能容易地进行各屏蔽构件40的接地。
(3)分离部42以预先成形为圆柱状的状态压接于端子构件60。
根据这样的结构，分离部42和端子构件60的固定操作进一步变得容易。
本实施方式能够按如下变更而实施。本实施方式及以下变更例能够在技术上不矛盾的范围内相互组合而实施。
·构成线束10的屏蔽导电路径13的数量能够任意变更。
·也能够将构成一个屏蔽导电路径13的电线11的数量设为三条以上。
·如图3及图4所示，例如也可以为：将六个屏蔽构件40中的三个屏蔽构件40的分离部42预先汇集为一个并成形为半分割圆柱状而得到成形体143，将剩余的三个屏蔽构件40的分离部42预先汇集为一个并成形为半分割圆柱状而得到成形体144，将成形体143和成形体144对接而形成为圆柱状，将该形成为圆柱状的结构压接于端子构件160。端子构件160具有基部161和从基部161延设的筒部162，基部161具有供螺钉63插通的螺孔，通过将筒部162敛紧成圆筒状，从而可压接呈圆柱状的分离部42。
根据这样的结构，使由各屏蔽构件40中的一部分的分离部42构成的成形体143和由剩余的分离部42构成的成形体144对接得到的结构呈圆柱状，因此将各屏蔽构件40的分离部42压接于端子构件160的操作进一步变得容易。另外，这样的成形体143、144的形状不限定于半分割圆柱状，能够变更为棱柱状等任意形状。
·各屏蔽构件40的分离部42和端子构件60的固定方式不限定于压接。能够采用钎焊、熔敷等其他的固定方式。
·也能够将各屏蔽构件40的分离部42预先汇集为平板状，以沿着母线50的外表面的状态利用金属制的敛紧环等紧固而固定。另外，在该情况下，也可以将使各分离部42汇集得到的结构利用钎焊、熔敷等直接固定于母线50。
·端子构件60不限于装配到母线50，只要是箱体的内部即可。
本公开包括以下安装例。并不用于限定，而作为辅助理解，标注实施方式的构成要素的附图标记。
