Component composite of two components used for current conduction, method for manufacturing a component composite, and use of a component composite

A method for manufacturing a component composite, comprising:

• providing a first component having a through opening;
• providing a second component having a connection section and a holding section;
• and
• installing the connection section of the second component into the through opening of the first component in an installation direction by applying a tensile force such that a friction-locked connection in the form of a press-fit connection is formed at least regionally between the through opening and the connection section in an installed state, wherein, during the installation, an ultrasonic vibration device is situated in operational connection with at least one of the first and second components;
• wherein the connection section and the holding section protrude beyond the first component in an area of the through opening in the installation direction in the installed state, and wherein the holding section has at least one area for an installation aid which is reduced in cross section in relation to the cross-sectional area of the through opening.
