Abstract: A connection unit includes an insulating mounting frame and multiple resilient press-on contacts situated on the mounting frame. Each press-on contact includes a helical pressure spring that can exert an elastic force on a metal contact body. The contact body is connected in one piece to a connection plug or a connection socket. For each press-on contact, the mounting frame includes a hollow cylinder that forms a cavity within a circumferential wall, the cavity being closed off by a cover that is situated so as to be axially displaceable at the wall of the hollow cylinder. The pressure spring is situated inside the cavity, and with its elastic force acts on the cover. The contact body, in one piece, forms a contact disk that is situated on the outer side of the cover.

Abstract: A multipole electrical plug-in connector includes a plug-in connector housing and a mounting block. The plug-in connector housing has a housing base that extends perpendicular to a longitudinal axis of the plug-in connector housing. The housing base has insertion openings. Contact elements are respectively inserted through the housing base insertion openings. Each contact element has a contact portion that is connectable to a mating plug-in connector, a press-in portion, with a fir tree profile, that is pressed into the housing base insertion opening in which the contact element is inserted through, and a connection portion for connecting an electrical connection line. Each contact element further has a retaining portion between the press-in portion and the connection portion. The retaining portions of the contact elements are inter-lockingly fastened in the mounting block. A method for producing a multipole electrical plug-in connector of this type is provided.
