Abstract
Abstract A multipolar plug has a two-piece plastic housing which partially confines one or more one-piece synthetic plastic inserts each of which has a centrally located retaining section removably engaging the housing and a two-part second section. One part of the second section is confined in the housing, and the other part constitutes one or more prongs which can enter a receptacle to engage their contact members with complementary contact members in the receptacle. Each second section carries two or four discrete strip-shaped contact members which are blanked from sheet metal and have central portions fully embedded in the respective retaining section. Each contact member further includes a second portion which is partially embedded in the first part of the respective second section, and a third portion which is partially embedded in the second part of the respective second section. The contact members are disposed, either singly or in pairs, at the opposite sides of the respective second section.
