High power joint electrical connector with cooling feature

An electrical connector assembly (100), comprising: a connector housing (112); a planar generatrix (124) having a rectangular cross-section defining two opposing major surfaces and four minor surfaces; a cooling plate (130) sized, shaped and arranged to be in thermally conductive contact with the first major surface of the planar busbar (124); and an L-shaped bus bar (118) partially disposed within the connector housing (112) and having a first end (120) connected to the electrical terminal (116) and a second end (122) attached to and in thermally conductive contact with the second major surface of the planar bus bar (124). The cooling plate (130) is configured to reduce the temperature of the planar bus bar (124) and the attached L-shaped bus bar (118). A method (200) of assembling such an electrical connector (100) is also provided. 一种电连接器组件(100)，包括：连接器壳体(112)；平面母线(124)，上述平面母线具有矩形横截面，上述矩形横截面限定有两个相对的主表面和四个副表面；冷却板(130)，上述冷却板的尺寸、形状和布置设计成与上述平面母线(124)的第一主表面导热接触；以及L形母线(118)，上述L形母线部分地配置在连接器壳体(112)内，并且具有第一端(120)和第二
