如图1-图4所示，本实施例提供一种DCDC电源转换器，其包括DCDC电源转换器的接插件2和壳体3，DCDC电源转换器的接插件2安装于壳体3上，该DCDC电源转换器的接插件2包括第一接插头21和第二接插头22。
具体地，接插件2用于连接DCDC电源转换器外部的功率线束和内部的印刷电路板，DCDC电源转换器的接插件2包括第一接插头21和第二接插头22，第一接插头21设置有第一功率端子211，第一功率端子211的第一端设置有接线螺柱2111，第一功率端子211的第一端通过接线螺柱2111连接于外部的功率线束。优选地，本实施例中，第一接插头21还包括信号端子212，信号端子212一端连接于外部的信号线束，另一端连接于印刷电路板1，以实现信号传递。第 二接插头22设置于印刷电路板1的下方，第二接插头22设置有第二功率端子221，第一功率端子211的第二端与第二功率端子221固定且电性连接，第一功率端子211通过第二功率端子221电性连接于印刷电路板1，以实现电路连接。本实施例中，DCDC电源转换器的接插件2为分体结构，减少DCDC电源转换器的接插件2内端子的体积，简化模具结构，第一接插头21和第二接插头22分别相较于现有技术的DCDC电源转换器的接插件，每个接插头的内部端子体积减小，产品设计简单，简化模具结构；两个独立的接插头，体积较小，铜排上的塑料包裹面积小，不容易开裂产生泄漏。
优选地，本实施例中第一功率端子211与第二功率端子221之间焊接连接，其中，焊接的方式为钎焊连接。在其他实施例中，第一功率端子211与第二功率端子221之间通过螺钉连接。上述方式，不仅实现了二者之间固定连接，还实现了二者之间通电连接。
本实施例中，第一接插头21包括第一本体213，第一功率端子211和信号端子212设置于第一本体213内，第一本体213为塑料，第一本体213、第一功率端子211和信号端子212通过注塑模具一体成型。第二接插头22包括第二本体222，第二功率端子221设置于第二本体222内，第二本体222为塑料，第二本体222与第二功率端子221通过注塑模具一体成型。
现有技术中，DCDC电源转换器的接插件内的端子结构复杂，由于注塑模具制作工艺的问题，很难把端子做成紧凑的结构，无法连接差模电感以降低DCDC电源转换器的接插件对外部器件的电磁干扰。本实施例中，第二接插头22内端子结构简单，所以能够在第二功率端子221上设置差模电感端子2211，差模电感端子2211电性连接于印刷电路板1上的差模电感，以实现降低DCDC电源转换器的接插件2对外部器件的电磁干扰。
优选地，第二接插头22还包括磁环23，第二接插头22的第二本体222上设置有安装位，磁环23安装于安装位内，且磁环23环设于差模电感端子2211外侧。磁环23的设置能够抑制电磁辐射向内或者向外的传输，提高了电磁兼容性能。进一步优选地，安装位为安装筋。需要说明的是，本实施例中磁环23为EMC磁环。
优选地，本实施例中，安装筋为两个或多个相对设置的半圆筋2221，磁环23通过点胶粘结于两个或多个半圆筋2221之间。在其他实施例中，磁环23能够卡接于安装筋内；或者，磁环23安装于安装筋之间，安装筋上设置有螺纹孔，螺栓螺纹连接于螺纹孔，以使螺栓端面抵接于磁环23。
本实施例中，差模电感端子2211包括多个差模电感子端子，多个差模电感子端子排布在直径不大于17mm的圆内；且多个差模电感子端子两两之间的间距不小于3mm，满足HTE(Hazardous Thermal Event)的要求，防止差模电感子端子之间内部短路。本实施例中，多个差模电感子端子为三个，分别为12V差模电感端子、48V差模电感端子和接地差模电感端子，48V差模电感端子和接地差模电感端子之间的距离为5mm,接地差模电感端子和12V差模电感端子之间的距离为3.3mm。本实施例中，磁环23的内径为18.75mm，磁环23外径为38mm。进一步优选地，磁环23的外表面还设置有绝缘镀层，绝缘镀层为高分子材料(树胶、橡胶或动物胶)、环氧基树脂等，避免磁环23破裂以后造成短路。
进一步地，第二功率端子221上还设置有共模电容端子2212，共模电容端子2212电性连接于印刷电路板1上的共模电容，使电路连接线路最短。
需要特别说明的是，本实施例中，第一功率端子211和第二功率端子221均包括相对应的三个端子，且三个端子分别为12V端子、接地端子和48V端子。为了满足焊接要求，端子表面做了镀层处理，镀层为锡、锌、银和镍四者中的 一种或至少两种以上的任意组合。每个第一功率端子211的第一端均设置有用于连接外部功率线束的接线螺柱2111。每个第二功率端子221上均设置有差模电感端子2211和共模电容端子2212。为了满足210A的峰值通电电流，第二功率端子221的横截面积设计成21mm 2。
注意，上述仅为本申请的较佳实施例及所运用技术原理。本领域技术人员会理解，本申请不限于这里所述的特定实施例，对本领域技术人员来说能够进行各种明显的变化、重新调整和替代而不会脱离本申请的保护范围。因此，虽然通过以上实施例对本申请进行了较为详细的说明，但是本申请不仅仅限于以上实施例，在不脱离本申请构思的情况下，还可以包括更多其他等效实施例，而本申请的范围由所附的权利要求范围决定。
