Abstract: An electrical connector system (200) is disclosed that includes a plurality of modular components. The modular components can include a receptacle housing (210, 503, 1410, 1610, 1810, 1910, 2162, 2610, 3010, 3410), a socket insert (212, 214, 400, 500), a socket electrical contact (410), a grounding spring (216, 218, 1916, 1918).The system includes matching orientation indicia on the polarization keys (220, 270) and housing windows (254) for viewing the indicia. The coupler (290) is slidably mounted on the plug assembly and include cam slots for causing mating and retraction of the plug (204) and receptacle (202) and also includes open position and engaged position indicator strips (2320, 2330, 2340). The system may include grounding springs (216, 218, 1916, 1918) for engaging the mounting panel and may be used with various types of backshells (2800, 2900 3100, 3200, 3300) including shield wire termination types.
