The connection section and a holding section of the second component protrude beyond the first component in the area of the through opening in the installation direction in the installed state, and 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. ## Claims ### Claim 1 A component composite for current conduction, comprising: a first component having a through opening; and a second component having a connection section and a holding section, wherein the connection section is configured to be inserted into the through opening in an installation direction 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 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. ### Claim 2 (depends on 1) The component composite as recited in claim 1, wherein the holding section includes a first area and a second area having different cross-sectional areas, the first area being on a side facing toward the connection section, and wherein the second area forms a frontal end of the second component and has a greater cross-sectional area than the first area. ### Claim 3 (depends on 2) The component composite as recited in claim 2, wherein the first area forms a predetermined breaking point at which shearing off of the holding section occurs when a predefined tensile force on the second component in the installation direction is exceeded. ### Claim 4 (depends on 3) The component composite as recited in claim 3, wherein the first area has a constant cross-sectional area. ### Claim 5 (depends on 3) The component composite as recited in claim 3, wherein a subarea which produces a notch effect is provided in the first area. ### Claim 6 (depends on 2) The component composite as recited in claim 2, wherein: the second component has an axial stop on a side facing away from the holding section; the axial stop rests against the first component in the installed state; and the axial stop has a cross-sectional area which at least regionally protrudes beyond the through opening. ### Claim 7 (depends on 3) The component composite as recited in claim 3, wherein the first and second components are composed of different materials. ### Claim 8 (depends on 1) The component composite as recited in claim 1, wherein the second component has a cavity for the installation aid, the cavity being radially delimited by a wall of the second component, and wherein at least one holding area which protrudes radially inward for the installation aid is situated on a frontal end of the cavity. ### Claim 9 (depends on 3) The component composite as recited in claim 3, wherein the component composite provide electrical contacting of battery poles in a lithium-ion battery. ### Claim 10 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.
