本发明要解决的课题Problems to be solved by the present invention
但是,在电动汽车或混合动力汽车等以电动机为驱动源的车辆中,为了流过大电流、高电压的电流而向电连接箱布线大直径的电线。另外,在使大电流、高电压的电流流过电线的情况下,需要使正极及负极的电线通过环状的铁氧体来抑制噪声。However, in a vehicle using an electric motor as a drive source, such as an electric vehicle or a hybrid vehicle, large-diameter electric wires are routed to the electrical connection box in order to flow a large current or a high-voltage current. In addition, when a large current or a high voltage current is passed through the electric wire, it is necessary to suppress noise by passing the positive and negative electric wires through ring-shaped ferrite.

具体实施方式Detailed ways
以下,参照各图对本发明的具体实施方式进行说明。Hereinafter, specific embodiments of the present invention will be described with reference to the drawings.
图1是应用了本实施方式的布线结构的电连接箱中的布线部件的连接部位的立体图。FIG. 1 is a perspective view of a connection portion of a wiring member in an electrical connection box to which the wiring structure of this embodiment is applied.
如图1所示,本实施方式的布线结构是将布线部件100布线到接线块等的电连接箱1(例如)的结构。电连接箱1具有两个端子部2、3。布线部件100具备汇流条10和电线60作为布线材料,并且汇流条10和电线60的端部紧固并连接到电连接箱1的端子部2、3。由此,布线部件100布线到电连接箱1。布线部件100的汇流条10和电线60是从电连接箱1连接到蓄电池等的布线材料,其中一方为正极,另一方为负极。As shown in FIG. 1 , the wiring structure of the present embodiment is a structure in which a
图2是布线部件的立体图。图3是将布线部件的铁氧体壳体拆下后的状态的立体图。Fig. 2 is a perspective view of a wiring component. 3 is a perspective view of a state in which a ferrite case of a wiring member is removed.
如图2及图3所示,具备汇流条10及电线60的布线部件100具有铁氧体部70。在铁氧体部70设有铁氧体71,该铁氧体71被绝缘树脂制的铁氧体壳体72覆盖。铁氧体71由一对分割铁氧体71a、71b构成,这些分割铁氧体71a、71b相互组合而形成为椭圆形的环状。As shown in FIGS. 2 and 3 ,
汇流条10及电线60穿过环状的铁氧体71,其外周在整个周向上被铁氧体71覆盖。由此,即使当高电压/大电流的电流流经汇流条10及电线60时,也可以通过铁氧体71抑制噪声的产生。在铁氧体71中,汇流条10及电线60形成为相互接近且并列布线的并列布线部10A、60A。The
与汇流条10并列设置的电线60由绝缘电线构成,该绝缘电线的芯线的外周被由绝缘性树脂构成的外皮覆盖,在电线60的一端部连接有具有孔部61a的端子金属件61。该电线60的设置在一端部的端子金属件61连接到电连接箱的端子部3,电线60的另一端部连接到例如蓄电池的端子。The
图4是构成布线部件的汇流条的立体图。Fig. 4 is a perspective view of a bus bar constituting a wiring member.
如图4所示,汇流条10形成为板状。该汇流条10例如由铜、铜合金、铝或铝合金等导电性金属材料构成的板材形成。该汇流条10的一端部为具有孔部21a的端子连接部(连接部)21,另一端部为具有孔部22a的电线连接部22。在汇流条10中,端子连接部21连接到电连接箱1的端子部2,电线23连接到电线连接部22。As shown in FIG. 4 , the
汇流条10的具有电线连接部22的另一端部侧形成为并列布线部10A。在该并列布线部10A中,汇流条10以使其宽度方向沿着汇流条10与电线60的排列方向的方式穿过铁氧体71。The other end side of the
汇流条10在并列布线部10A的与电线连接部22相反侧的端部具有向水平方向直角弯曲的水平弯曲部10B。而且,汇流条10具有在水平弯曲部10B弯曲并相对于并列布线部10A向侧方延伸的水平延伸部10C。该水平延伸部10C的与并列布线部10A相反侧的端部具有垂直弯曲的垂直弯曲部10D。垂直弯曲部10D的端子连接部21侧成为向与电线连接部22相反侧延伸的垂直延伸部10E。该垂直延伸部10E的端子连接部21侧的端部具有垂直弯曲的垂直弯曲部10F,该垂直弯曲部10F的与垂直延伸部10E相反侧成为端子连接部21。这样,汇流条10在水平弯曲部10B、垂直弯曲部10D、10F弯曲而改变延伸方向。The

如图5及图6所示,汇流条10的除了端子连接部21和垂直延伸部10E的一部分之外的部分被壳体30覆盖。壳体30由第一壳体31和第二壳体32构成。As shown in FIGS. 5 and 6 , parts of the
第一壳体31安装在汇流条10的下方侧,汇流条10的下方侧被第一壳体31覆盖。第二壳体32安装在汇流条10的上方侧,汇流条10的上方侧被第二壳体32覆盖。第二壳体32从上方侧组装到安装在汇流条10上的第一壳体31上。由此,第一壳体31和第二壳体32安装到汇流条10上,并且汇流条10被由第一壳体31和第二壳体32构成的壳体30覆盖。The
由第一壳体31和第二壳体32构成的壳体30具有多个锁止部37。锁止部37由形成于第一壳体31的卡止爪38和形成于第二壳体32的卡止孔39构成。通过将第二壳体32组装到安装于汇流条10的第一壳体31上,卡止爪38进入卡止孔39中,从而使锁止部37卡止。由此,在第一壳体31与第二壳体32组装后的状态下被锁止。The
图7是打开盖部的状态的收纳部的立体图。图8是关闭盖部的状态的沿布线方向的收纳部的纵剖面图。Fig. 7 is a perspective view of the storage unit in a state where the lid is opened. 8 is a vertical cross-sectional view of the storage portion along the wiring direction in a state where the lid portion is closed.
如图7及图8所示,壳体30具备具有收纳空间S的收纳部40,并且汇流条10的电线连接部22与电线23的连接部收纳在该收纳部40的收纳空间S中。电线23由将芯线的外周用由绝缘性树脂构成的外皮覆盖的绝缘电线构成,例如与蓄电池的端子连接。电线23在其端部连接有具有孔部24a的端子金属件24,连接有该端子金属件24的端部被收纳在收纳部40的收纳空间S中。As shown in FIGS. 7 and 8 , the
收纳部40具有底壁部41、周壁部42和盖部43,由这些底壁部41、周壁部42和盖部43形成收纳空间S。底壁部41形成于第一壳体31,周壁部42及盖部43形成于第二壳体32。The
周壁部42由相互相对的两个侧壁部44和与这些侧壁部44的端部连接设置且相互相对的两个端壁部45构成。周壁部42设成从底壁部41的周缘竖立设置。在构成周壁部42的一端壁部45上形成有引出凹部45a,电线23穿过该引出凹部45a。The
盖部43经由铰链部46与构成周壁部42的一侧壁部44一体地成形。盖部43通过铰链部46相对于侧壁部44可转动地连结。在构成周壁部42的另一侧壁部44上形成有卡止部44a,这些卡止部44a能够卡止在形成于盖部43的与铰链部46的形成侧相反侧的缘部的卡止孔43a中。The
在构成收纳部40的底壁部41上竖立设置有双头螺栓48。在双头螺栓48插入到孔22a中的状态下,汇流条10的电线连接部22收纳于收纳空间S中。在该电线连接部22上,重叠有在孔部24a中插入了双头螺栓48的电线23的端子金属件24。而且,螺母(紧固件)49与双头螺栓48螺合而紧固,由此,使汇流条10的电线连接部22与电线23的端子金属件24紧固。
收纳汇流条10与电线23的连接部位的收纳部40通过转动盖部43而覆盖周壁部42的上部来堵塞收纳空间S。此时,盖部43的卡止孔43a卡止于侧壁部44的卡止部44a。由此,盖部43的转动被限制,从而维持收纳空间S被堵塞的状态。The
另外,在盖部43上形成有凹部51,该凹部51在堵塞收纳空间S的状态下供双头螺栓48的前端插入。在该凹部51的周缘部形成有卡合壁52。在盖部43堵塞收纳空间S的状态下,卡合壁52的突出尺寸为,其端面无间隙地配置在紧固于双头螺栓48上的螺母49的相对位置。因此,当螺母49向双头螺栓48的紧固不充分时,由于螺母49浮起,所以盖部43的卡合壁52的端面碰到螺母49。因此,无法通过盖部43完全关闭收纳空间S,侧壁部44的卡止部44a不能卡止于盖部43的卡止孔43a中,由此,能够检测汇流条10的电线连接部22与电线23的端子金属件24之间的连接故障。In addition, a
如上所述,根据本实施方式的布线结构,因为汇流条10及电线60穿过环状的铁氧体71,所以能够通过铁氧体71抑制电流流过汇流条10及电线60时的噪声的产生。As described above, according to the wiring structure of the present embodiment, since the
另外,汇流条10在与电连接箱1连接的端子连接部21和插入到铁氧体71中的并列布线部10A之间沿着电线60的排列方向弯曲。因此,可以将汇流条10从与电连接箱1连接的连接部位顺利地引导到与电线60相邻的铁氧体71中。因此,由电线60和汇流条10构成的多个布线材料能够穿过环状的铁氧体71而顺利地布线到电连接箱1中。In addition, the
另外,由于覆盖汇流条10的壳体30具备具有收纳空间S的收纳部40,在该收纳空间S中收纳汇流条10与端子金属件24的连接部位,所以能够将汇流条10与端子金属件24的连接部位收纳并保护在收纳部40的收纳空间S中。另外,通过打开盖部43,能够目视收纳空间S内的汇流条10与端子金属件24的连接部位,确认螺母49的有无和连接状态。In addition, since the
而且,盖部43具有卡合壁52,该卡合壁52在将收纳空间S关闭的状态下无间隙地配置在螺母49的相对位置。因此,当螺母49松动而浮起时,卡合壁52碰到螺母49,无法关闭盖部43,由此,能够检测出汇流条10与端子金属件24的连接不良。另外,由于盖部43可转动地设置在周壁部42上,因此能够削减部件数量。Furthermore, the
另外,汇流条10的并列布线部10A以宽度方向沿着与电线60的排列方向的方式穿过铁氧体71。因此,通过以使汇流条10与电线60的排列方向为水平方向的方式将布线部件100布线到车辆中,能够抑制高度的增大,并且能够顺利地布线到高度受限的车辆的狭窄的布线空间中。In addition, the
接着,对收纳部的变形例进行说明。Next, modified examples of the storage unit will be described.
图9是打开第一变形例的收纳部的盖部的状态的立体图。图10是关闭第一变形例的收纳部的盖部的状态下的沿布线方向的收纳部的纵剖面图。Fig. 9 is a perspective view of a state in which a lid of a storage section according to a first modification is opened. 10 is a vertical cross-sectional view of the storage unit along the wiring direction in a state in which the cover of the storage unit according to the first modification is closed.
如图9及图10所示,第一变形例的收纳部40A具备与周壁部42分体的盖部43。As shown in FIGS. 9 and 10 , 40A of accommodating portions according to the first modified example include
周壁部42在一侧壁部44上具有一个卡止部44a,在另一侧壁部44上具有两个卡止部44a。另外,盖部43在一缘部具有一个卡止孔43a,在另一缘部具有两个卡止孔43a。The
在该变形例的收纳部40A中,通过将盖部43覆盖在周壁部42的上部,使周壁部42的卡止部44a分别卡止在盖部43的卡止孔43a中。由此,在周壁部42的上部组装盖部43,由盖部43堵塞收纳空间S。In the
在该收纳部40A的情况下,当螺母49向双头螺栓48的紧固不充分,螺母49浮起时,盖部43的卡合壁52的端面碰到螺母49。因此,无法将盖部43组装到周壁部42上,从而能够检测出汇流条10的电线连接部22与电线23的端子金属件24之间的连接不良。特别地,在收纳部40A中,由于盖部43的卡合壁52的端面碰到螺母49,而使盖部43从周壁部42脱落,因此,能够更精确地检测到汇流条10的电线连接部22与电线23的端子金属件24之间的连接不良。In the
图11是第二变形例的收纳部的立体图。图12是第二变形例的收纳部的侧面图。图13是第二变形例的收纳部的侧面图。Fig. 11 is a perspective view of a storage unit according to a second modified example. Fig. 12 is a side view of a storage unit according to a second modified example. Fig. 13 is a side view of a storage unit according to a second modification.
如图11和图12所示,在第二变形例的壳体30中,设有从端壁部45向电线23的延伸方向突出的电线引出导向件84,能够使用捆束带80将电线23固定在电线引出导向件84上。As shown in FIG. 11 and FIG. 12 , in the
捆束带80具有带部82和头部81,该头部81中插通有带部82,并设有阻止向返回方向移动的未图示的卡合爪。引出引导件84具有与电线23一起被捆束带80的带部82捆束的曲面部86、以及形成在曲面部86的两端的端部87、88。在端部87、88形成有使带部82向电线侧贯通并且比捆束带80的头部81小的贯通孔。因此,当捆束带80沿电线23的外周方向旋转时,头部81与端部87的侧面87a或端部88的侧面88a抵接,从而旋转方向的移动被限制。The binding
捆束带80可能由于车辆的振动而沿着电线23的外周移动。因此,如图13所示,在电线引出导向件84的附近设置有其他部件90的情况下,如果不限制头部81的移动,则会产生头部81与其他部件90干涉的可能性,但在第二变形例的壳体30中,头部81与端部88的侧面88a抵接而不会进一步移动,因此能够防止头部81与其他部件90干涉。The binding
在上述实施方式中,以使宽度方向沿着与电线60的排列方向的方式将汇流条10与电线60一起穿过铁氧体71,然而,如图14所示,汇流条10也可以使宽度方向正交于与电线60的排列方向的方式穿过铁氧体71。在这种情况下,在使汇流条10与电线60的排列方向沿着水平方向的方式搭载到车辆上的状态下,即使在施加车辆的上下方向的振动时,也能够抑制由振动引起的汇流条10的移位,并且能够将汇流条10配置成稳定的状态。In the above-mentioned embodiment, the
另外,本发明不限于上述实施方式,可以适当地进行变形、改进等。此外,上述实施方式中的各构成要素的材质、形状、尺寸、数量、配置部位等只要能够实现本发明可以是任意的,并不限定于此。In addition, this invention is not limited to the above-mentioned embodiment, Deformation, improvement, etc. are possible suitably.

It is arranged at the opposite position of the fastener (nut 49 ) without any gap.
根据上述[3]的构成的布线结构,在使盖部转动而关闭收纳空间的状态下,卡合壁无间隙地配置在紧固件的相对位置。因此,当紧固件松动而浮起时,卡合壁碰到紧固件,不能关闭盖部,由此,能够检测出汇流条与端子金属件的连接不良。另外,由于盖部可转动地设置在周壁部上,所以能够削减部件数量。According to the wiring structure configured in the above [3], in a state where the storage space is closed by rotating the cover portion, the engaging wall is disposed at a position facing the fastener without a gap. Therefore, when the fastener loosens and floats, the engaging wall hits the fastener, and the cover cannot be closed, whereby poor connection between the bus bar and the terminal metal fitting can be detected. In addition, since the cover portion is rotatably provided on the peripheral wall portion, the number of components can be reduced.
