具体实施方式
以下，参照附图，对本发明的电力变换装置的实施方式进行说明。此外，各图中对相同要素标注相同的符号，并省略重复的说明。
图1是本实施方式的DC-DC转换装置100的高电压连接部的高电压电源电力线和连接检测线的电路结构图的例子。此外，以下的记载中以DC-DC转换器为例进行记载，但在电力线和连接检测线被包括在同一连接器内的其它电力变换装置中也能够应用。并且，在实施例中作为代表例而进行高电压连接器的记载，但不依赖于电压。
上述的高电压连接器由车辆侧连接器300和装置侧连接器200构成。由车辆侧供给的数百V的高电压电源如图1的电路结构图的例子那样经由高电压电源布线电缆350内的高电压电源电力布线310直至车辆侧连接器300。在DC-DC转换装置100设有与车辆侧连接器300配合的装置侧连接器200。装置侧连接器200和DC-DC转换器内部电力电路通过高电压电源电力线210连接。在车辆侧连接器300和装置侧连接器200这两个连接器正常配合的情况下，高电压电源电路与DC-DC转换器内部电力电路连接，而供给高电压电力。
并且，如图1所示，在该高电压连接器内部设有用于检测高电压连接器的配合状态的多个连接检测线220、320。图1的连接检测线220、320是最简单的例子，使用两端子的连接检测线，其由以下的结构构成。车辆侧连接器300的连接检测线320是通过布线材料将两端子间短路的结构，在另一个装置侧连接器200以及DC-DC转换装置的内部电路(控制电路等)侧设有连接检测信号产生电路270和连接检测信号检测电路280。
此处，若车辆侧连接器300和装置侧连接器200正常配合，则高电压电源电力线310与高电压电源电力线210连接，并且连接检测线320也与连接检测线220连接。而且，通过由连接检测信号检测电路280对连接检测线220的两端子的电信号状态进行运算检测，而能够在DC-DC转换装置100侧检测高电压连接器的连接状态。此外，用于连接检测的端子个数、电路方式不限定于上述情况，若是以电方式检测的结构则也可以是其它的方式。
图2是DC-DC转换装置100的高电压连接部的高电压电源电力线和连接检测线的电路结构的其它构成例。连接检测信号产生电路270和连接检测信号检测电路280也可以如图1那样在与高电压连接器直接连接的DC-DC转换装置100内构成，但也可以如图2那样构成为，遍及多个产品对连接检测线220进行布线，在不与高电压连接器直接连接的其它装置900，配置连接检测信号产生电路270和连接检测信号检测电路280。
图1以及图2中，从装置侧连接器200向DC-DC转换装置100中导入高电压电源电力线210以及连接检测线220，而在本实施方式的电力变换装置中，在该导入部配置环状芯部件500。以下，使用附图详细地对图1的电路结构进行说明。
图3是采用了图1的电路结构的车辆侧连接器300的构成例。图3(a)是车辆侧连接器300的侧视图。图3(b)是从DC-DC转换装置100侧观察车辆侧连接器300时的侧视图。
车辆侧连接器300具有将与车辆的高电压电源电路连接的高电压电源布线电缆350与设置于DC-DC转换装置100侧的装置侧连接器200连接配合而一并连接多个电气电路的功能。
车辆侧连接器300在该连接器内部具备两根高电压电源电力布线310、两根连接检测线320以及连接上述各个布线的接点端子330。此处，接点端子330与后述的装置侧连接器200的接点端子230嵌合，并进行电连接。
高电压电源电力布线310各自的一端向接点端子330布线，另一端向车辆侧的高电压电源电路布线。连接检测线320的两端分别向一个接点端子330布线。因此，在车辆侧连接器300内设置四个接点端子330。
这些高电压电源电力布线310、连接检测线320、接点端子330容纳于筒状的导电金属制连接器外壳390内。此处，本实施例中，连接检测线320尤其以未进行屏蔽处理等的布线材料来进行最短布线。
图4是采用了图1的电路结构的装置侧连接器200的构成例。图4(a)是从与车辆侧连接器300的嵌合方向观察装置侧连接器200的侧视图。图4(b)是装置侧连接器200的侧视图。图4(c)是从DC-DC转换装置内部侧观察装置侧连接器200时的侧视图。
装置侧连接器200具有与车辆侧连接器300连接配合、而一并连接向车辆侧连接器300布线的多个电气电路和导入DC-DC转换装置100的内部的多个电气电路的功能。
装置侧连接器200在该连接器内部具备两根高电压电源电力线210、两根连接检测线220以及连接上述各个布线的接点端子230。此处，接点端子230与上述的车辆侧连接器300的接点端子330嵌合，并进行电连接。
高电压电源电力线210各自的一端向接点端子230布线，另一端向DC-DC转换装置的内部电力电路(未图示)布线。连接检测线220各自的一端向接点端子230布线，另一端向DC-DC转换装置的控制电路(未图示)侧布线。本实施方式中，由于高电压电源电力线210和连接检测线220分别各设置两根，所以设置四个连接端子230。
这些高电压电源电力线210、连接检测线220、连接端子230容纳于筒状的导电金属制连接器外壳290内。导电金属制连接器外壳290形成为与车辆侧连接器的导电金属制连接器外壳390配合连接的形状，并进行电连接。该结构在连接器配合连接部中实现对箱体电位所引起的噪声进行遮挡的效果，但不是必需的。
此外，本实施例中，连接检测线220尤其以未进行屏蔽处理等的布线材料进行布线，但也可以使用绞合线、屏蔽线。并且，图例中，为了缠绕多根线材，或者为了物理性地保护线材，将连接检测线220插通于管240，但这并不是必需的。
在装置侧连接器200的导电金属制连接器外壳290，设有用于将DC-DC转换装置固定保持于箱体的多个螺纹固定用孔293、圆筒状的箱体导入部291、以及抑制水等从该圆筒状的箱体导入部291向箱体内部侵入的O型圈292。
图5是环状芯部件500的构成例。环状芯部件500由以磁性体形成的环状磁性体芯510和外装部件520构成。环状磁性体芯510是形成贯通孔511的环状部件。外装部件520是对环状磁性体芯510的外周进行覆盖的绝缘部件。
本实施方式中使用的环状磁性体芯510使用与图4的圆筒状的箱体导入部291类似的外形形状的圆环形状的芯。然而，若芯形状是环状则不特别限制其外形形状，考虑装置侧连接器200的箱体导入部291的形状、DC-DC转换装置100的箱体101的加工容易度等而适当地选择即可。
环状磁性体芯510的周围由用于使芯材电绝缘的外装部件520构成。图例中，由外装部件520A和外装部件520B这两个部件构成，但外装部件520并不限定于图例，若能够实现环状磁性体芯510的绝缘则也可以采用其它的方法(例如树脂涂层、绝缘膜涂装等方法)。此外，由于也有因芯材料(例如Ni-Zn系芯材料等)而不需要绝缘的情况，所以外装部件520不是必需的。
图6是装置侧连接器200和箱体101的组装例。在箱体101，设有用于对于装置侧连接器200进行固定保持的螺纹孔193、和与装置侧连接器200的箱体导入部291的形状配合的开口部(安装、布线用孔)120。装置侧连接器200从箱体101外侧方向安装固定于开口部120。
为了在箱体101安装固定装置侧连接器200，而在箱体101形成从箱体101外壁面突出的安装部。为了确保设于装置侧连接器200的箱体导入部291的O型圈292与开口部120内壁的接触，并且为了形成螺纹孔193，该安装部从箱体101外壁面突出。并且，通过使之从箱体101外壁面突出，来确保容纳于开口部120的环状芯部件500的容纳深度。并且，车辆侧连接器300的安装变得容易，组装性提高。
通过在形成于该装置侧连接器200的螺纹孔293以及形成于箱体101的螺纹孔193贯通螺纹件，来将装置侧连接器200安装于箱体101。装置侧连接器200的导电金属制连接器外壳290通过直接固定于箱体101，而与箱体101同电位地连接。
另一方面，如后述，在图7以及图8中，在隔着箱体101而与装置侧连接器200相反的一侧、即箱体101内侧，安装有环状芯部件500和分隔部件600。
图7(a)是表示将装置侧连接器200和环状芯部件500组装于箱体101的构成例的立体图。图7(b)是表示将分隔部件600组装于箱体101的构成例的立体图。
如图6中所示那样，装置侧连接器200在形成于箱体101的开口部120安装。如图7(a)所示，一个环状芯部件500从箱体101的内部侧安装于该开口部120。而且，装置侧连接器200的高电压电源电力布线210和连接检测线220通过形成于环状芯部件500的贯通孔501而被导入箱体101内部。
当然对照环状芯部件500的外形形状地对供环状芯部件500安装的箱体101内侧的开口部120进行形状加工，环状芯部件500成为容纳于箱体壁面内的状态。图7(b)所示的图例中，成为在箱体壁面内容纳环状芯部件500整体的结构，但也可以是不容纳整体而一部分露出的结构。
通过像这样构成，由于来自装置侧连接器200的高电压电源电力布线210和连接检测布线220在环状芯部件500的贯通孔501穿过，所以相对于各个布线电路作为共模扼流圈发挥功能，而能够构成共模噪声抑制用滤波电路。即，如图1或图2所示，高电压电源电力布线210和连接检测布线220分别配设于DC-DC转换装置100内部的各电路基板，而通过使这些布线一并地贯通环状芯部件500，能够在更接近噪声混入点的位置除去与布线重叠的共模噪声。
并且，本实施方式的环状芯部件500容纳于箱体101的开口部120，从而能够不使布线部大型化地实现上述的功能。
图8是表示将分隔部件600组装于箱体101的构成例的立体图。在环状芯部件500插入于箱体101的开口部120的状态下，如图7(b)所示，分隔部件600配置于与该环状芯部件500对置的位置。在环状芯部件500保持固定于箱体101的状态下，分隔部件600固定于箱体101。作为将分隔部件600固定于箱体101的固定方法，有例如如图8所示利用螺纹件的紧固等方法。
图9(a)是以图8的剖面A切断后的俯视剖视图。图9(b)是以图8的剖面B切断后的侧视剖视图。
分隔部件600具有分隔壁610、芯固定部620以及螺纹固定用孔630。螺纹固定用孔630用于将分隔部件600固定于箱体101。芯固定部620形成为，当从贯通孔501的轴线方向观察时，该芯固定部620的投影部与环状芯部件500的形成有贯通孔501的区域以外的区域重叠。
并且，芯固定部620以将环状芯部件500压入箱体101的开口部120的方式形成为凸形剖面形状，且凸形剖面形状前端朝向箱体101的外侧按压环状芯部件500。即，如图9(b)所示，在该凸形剖面形状的前端部，向箱体101的壁面方向按压环状芯部件500并对其进行固定保持。由此，环状芯部件500被夹持在形成于箱体101的开口部120的内壁与芯固定部620之间。
并且，如图9(a)所示，芯固定部620封堵贯通孔501的开口的一部分，由此将该开口区域二分割为芯固定部620的一侧区域和另一侧区域。贯通环状芯部件500的高电压电源电力布线210和连接检测布线220配置为，高电压电源电力布线210相对于芯固定部620铺设于一侧，连接检测布线220相对于芯固定部620铺设于另一侧。
这样，芯固定部620形成为，在分隔部件600固定于箱体101的状态下，抑制高电压电源电力布线210以及连接检测布线220在通过环状芯部件500的贯通孔501后的布线过程中分别交叉。此外，形状并不需要一定是凸形剖面，是能够抑制布线交叉、且能够固定环状芯部件500的形状即可。
分隔部件600的分隔壁610从芯固定部620的一部分朝向箱体101的外侧方向突出。分隔壁610向固定保持于箱体101的开口部120的环状芯部件500的贯通孔501内突出。由此，环状芯部件500的贯通孔501的空间被二分割为分隔壁610的一侧空间和另一侧空间。
如图9(a)所示，高电压电源电力布线210在环状芯部件500的贯通孔501内的空间内相对于分隔壁610铺设于一侧空间。另一方面，连接检测布线220在环状芯部件500的贯通孔501内的空间内相对于分隔壁610铺设于另一侧空间。这样，通过设置能够分割配置那样的分隔壁610，能够抑制高电压电源电力布线210和连接检测布线220在环状芯部件500的贯通孔501内部的布线交叉。
通过像这样构成，相对于箱体开口部120铺设于右侧的高电压电源电力布线210在环状芯部件500的贯通孔501内也配置于右侧，相对于箱体开口部120铺设于左侧的连接检测布线220在环状芯部件500的贯通孔501内也配置于左侧。另外，在箱体开口部120的布线引出部，利用形成为凸形剖面形状的芯固定部620，高电压电源电力布线210被定位为朝向右方向，且连接检测布线220被定位为朝向左方向。
由此，防止在共模滤波器通过后高电压电源电力布线210和连接检测布线220邻接交叉，能够将两布线间的空间距离确保为一定量，从而能够抑制空间传播所引起的噪声混入。
此外，上述中，芯固定部620以及分隔壁610向左右方向分割空间，但当然分割方向不限定于左右，应该根据布线铺设方向来变化。并且，分割空间个数不限定于必需是二分割，也可以根据布线个数来变化，若保证分隔形状则壁面形状不是必需的。
此外，分隔部件600也可以由绝缘体构成，但也可以是导体，也可以复合绝缘体和导体而构成。若将分隔部件600的分隔壁610以及凸形剖面形状的芯固定部620设为导体，并给予与箱体101相同的基准电位(GND电位)，则分隔形状部得到电方式的遮挡效果，从而对于抑制空间传播所引起的噪声混入更加有效。
此外，本实施例中，从箱体101内侧安装环状芯部件500，但也可以是从箱体101外侧进行安装的结构。即，是如下方法：在安装装置侧连接器200前，从箱体101外侧方向将环状芯部件500插入于开口部120，之后安装装置侧连接器200。在该情况下，若变更上述的分隔部件600的凸形剖面形状壁的一部分来对应，则得到相同的效果。
