Electrical connection unit having spring-loaded press-on contacts

A connection unit comprising:

• an insulating mounting frame;
• a plurality of resilient press-on contacts arranged on the mounting frame, each press-on contact including a pressure spring and a contact element, the contact element including a plastic cover and a metallic contact body, the contact body being connected in one piece to an electrical connector;
• and
• for each press-on contact, the insulating mounting frame including a hollow cylinder that forms a cavity within a wall, the cover of the contact element of the press-on contact closing off the cavity of the hollow cylinder for the press-on contact and fitting over and extending around an outer perimeter of the wall of the hollow cylinder so as to be axially displaceable on the wall of the hollow cylinder, the pressure spring of the press-on contact being situated within the cavity of the hollow cylinder and acting on an inner side of the cover with an elastic force and thereby exerting the elastic force on the contact body, and the contact body of the contact element of the press-on contact in one piece forms a metallic contact disk that is situated on an outer side of the cover.
