Description

逆变器模块
技术领域
本发明涉及逆变器模块，特别是将连接器与逆变器外壳形成一体，从而缩减部件数量、组装工程的逆变器模块。
背景技术
一般，使用引擎和电机来驱动的混合动力汽车与只用电机来驱动的电动汽车，在驱动电机时需要高的电压及电流。
因此，混合动力汽车与电动汽车上必须具备：高电压电池及低电压电池；逆转器，与转换器一起将电池的DC电压转换为三相AC电压并控制电机旋转数，所述转换器为将电池电压转换为用于驱动电机的电压和提供给电子设备的12V的低电压。
图3表示，根据传统的混合动力车辆与逆变器一同构成的例子。
如图所示，混合动力车辆的电机(MG1)、发电机(MG2)及引擎为基本构成，由高电压电池和低电压电池构成的电池5；通过电源电缆6与电池5连接，与转换器一同模块化的逆变器1为必备构成。
所述逆变器1中，连接器100与构成整体形象的外壳的一侧面部突出的连接法兰3相结合；像这样，另外结合连接器100的逆变器1的结构称为连接器分离型逆变器。
如上所述构成的连接器100，为了将3相AC电压与电机和发电机相连接，而应用分别需要三个电线的3相逆变器上时，因为3相逆变器为了连接各3相，而由三个母线构成。因此，连接器100的接头也同样由三个构成。
作为逆变器的特征，将DC电压转换成AC电压，并输出到电机和发电机，由此，其具备的连接器100同样由分别输出到电机与发电机的一对第一及第二连接器200、300构成，所述一对第一及第二连接器200、300分别夹入形成在逆变器1连接器法兰3上的一对连接器孔3a、3b上，并形成螺栓紧固。
所述一对第一及第二连接器200、300的相互公用化，可以减少其大小，但，因为电机与发电机各拥有不同的规格，因此不能实现相互公用化。
图4表示传统的逆变器模块中所需的连接器部件数量与组装工程。
如图4(a)所示，组装完成的一对第一及第二连接器200、300分别与形成在逆变器1上的连接器法兰3的一对连接器孔3a、3b相结合后，在逆变器1的内部与母线500电连接。
图4(b)是与一对第一及第二连接器200、300电连接的母线500，如图所示，母线500利用框架构成了一体化的第一及第二母线501、502，所述第一及第二母线501、502根据三相逆变器的特性，分别具备三个母线。
图4(c)是连接器100与母线500在逆变器内部形成电连接的组装状态。如图所示，分别夹入形成在逆变器1上的连接器法兰3的一对连接器孔3a、3b上的第一及第二连接器200、300分别与第一及第二母线501、502连接，并与电池5和电缆6相连接，实现电连接状态。
在这种状态下，如图3所示，连接于电机与发电机方向上的相对部件连接器400夹入第一及第二连接器200、300上时，电池5和逆变器1及电机和发电机形成相互的电路。
然而，同所述安装在逆变器1外部的连接器100，应当在夹入连接器法兰3的连接器孔3a、3b后形成螺栓紧固，其内部与作为其他部件的母线500一同连接，由此，连接器100必然需要为了与逆变器1一起安装的足够大小的空间。
通常，连接器100因其构成部件，而拥有限定的空间大小，因此，几乎没有能缩小的空间，像这样，连接器100无法缩小大小的问题，成为了逆变器1大小增加的原因之一。
另外，连接器100还具有由构成部件引起易损性，例如图3中的第一连接器200，由与外壳结合的接头连接器202、密封所需的封条203、固定所需的螺母204及为了电连接与母线连接的接头205构成。因此，必然引起许多部件组装工程所导致的费用增加。
如上所述连接器100费用增加也是导致逆变器1费用增加的另一个原因。
与此同时，连接器100必须具备，与逆变器1的密封面；固定所需的螺母组装及螺纹加工工程；以及在逆变器1的内部，为了与连接器100进行电连接所需的母线500。这是在整体上导致增加逆变器组装工程及费用的另一个原因。
发明内容
（要解决的技术问题）
本发明是为了解决如上所述的问题而提出的，本发明的目的在于提供一种逆变器模块，连接器一体成型到逆变器外壳上，形成子部件，由于能够缩小连接器的占有空间，因此，不但制作大小更紧凑；而且可以除去安装连接器时所需的密封处理及紧固工程，尤其是因为部件数量的减少，使组装工程最小化，从而降低费用。
（解决问题的手段）
为了达成所述目的，提供一种逆变器模块，由电机、发电机、引擎以及由电池和转换器形成模块化的逆变器构成的混合动力汽车中，包括：一对第一及第二连接器外壳，与构成所述逆变器的逆变器外壳的一侧面部位形成一体；第一及第二母线，分别与所述第一及第二连接器外壳相结合，具备与所述电池形成电连接状态且与电缆相接的接头；连接器，与所述第一及第二连接器外壳的下端相结合，分别插入所述第一及第二母线端子的第一及第二接头。
本发明所述的逆变器模块，所述第一及第二连接器外壳与所述逆变器外壳是由同一材质构成。
本发明所述的逆变器模块，所述第一及第二母线利用支架形成一体化，在一体化的状态下，所述第一母线与所述第二母线相互保持间隔并结合。

具体实施方式
下面参照附图对根据本发明的制动装置的实施例进行说明。在此过程中，但这仅仅是例示性的实施例，本发明所属技术领域的普通技术人员应当理解，能够从中实现多种变形及等同的其他实施例。因此，不局限于此处说明的实施例上。
图1(a)表示具备根据本实施例连接器一体型逆变器模块的混合动力车辆的构成。
如图所示，混合动力车辆由电机(MG1)、发电机(MG2)及引擎为基本构成，由高电压电池与低电压电池构成的电池5、与电池5通过电源电缆6相连接的转换器4一同模块化的逆变器1为必备构成，所述逆变器1中具备利用逆变器外壳一体成型的连接装置10。
所述连接装置10由将DC电压转换成AC电压，并分别输出到电机和发电机上的一对第一及第二连接器20、30构成，为了方便起见，以输出到电机的连接器为第一连接器20、以输出到发电机的连接器为第二连接器30来区分。
图1(b)是构成连接装置10的一对第一及第二连接器20、30的分离构成图，如图所示，第一连接器20由，与逆变器外壳一体成型的连接器外壳21；插入于连接器外壳21内部空间，与电池5及电缆6形成电连接状态的第一母线22；以及夹在连接器外壳21上，与第一母线22相结合的接头连接器23构成。
在此，所述第一母线22是由三个接头22a形成，所述数据头23形成可以插入三个接头22a的三个插槽，这是因为根据三相型逆变器而适用三个电线所导致的。
此外，所述第二连接器30由，与逆变器外壳一体成型的连接器外壳31；插入于连接器外壳31内部空间，与电池5及电缆6形成电连接状态的第二母线32；以及夹在连接器外壳31上，与第二母线32相结合的接头连接器33构成。
在此，所述第一母线32是由三个接头32a形成，所述接头连接器33形成可以插入三个接头32a的三个插槽，这是因为根据三相类型逆变器而适用三个电线所导致的。
图2表示根据本实施例的逆变器模块中所需要的连接器部件数量及组装工程的装配图。
如图2(a)所示，构成第一连接器20与第二连接器30的连接器外壳21、31是利用形成逆变器外壳的一侧面部位的连接器法兰3形成一体。这是起因于连接器法兰3和连接器外壳21、31是由同一材质构成。
如上所述，连接器法兰3与第一及第二连接器外壳21、31形成一体，与所述第一及第二连接器外壳21、31，如传统的方式，需要夹在另外制作的连接器法兰3并结合时相比，会位于更内侧，根据这样的位置变化能进一步缩小连接器法兰3的大小，由此还能缩小逆变器外壳的整体大小。
此外，如图2(b)所示，分别具备三个接头22a、32a的第一及第二母线22、32利用形成支架一体化的母线25，不仅能减少母线25的组件，还能使整体的构造简化，尤其是能够减少母线25一体化结构的螺栓数量及紧固工数。
尤其是，如上所述的一体化母线25来实现连接器的电连接，与传统的方法相比，即另制造的母线与连接器相结合时相比，能够大量减少组装工程，尤其是去除或者减少另外制作的构成连接器的接头连接器、封条及多个螺母和多个接头等组件，对连接器的结构简化起到很大的作用。
因此，本实施例中，大量减少了一对第一及第二连接器20、30和连接器法兰3之间的结合工程及母线和接头之间的连接工程，与传统的另外制作连接器相比较时，意味着减少了组装工程。
即，如图2(c)所示，组装一对第一及第二连接器20、30时，将分别具备三个接头22a、32a的第一及第二母线22、32由支架一体化的母线25夹入到第一及第二连接器外壳21、31的上方并固定位置后，将接头连接器23、33夹入到第一及第二连接器外壳21、31的下方，并与第一及第二母线22、32的接头22a、32a相结合。这能提供，通过这样极为简单的组装过程就可以完成组装的便利性。
尤其，根据本实施例，利用逆变器外壳一体型第一及第二连接器外壳21、31及接头一体型母线25构成一对第一连接器20及第二连接器30，使缩小逆变器的体积变得可能，因此能够制造出大量减少整体大小的紧凑的逆变器。
