Fastening anchor for battery, method for producing battery, battery and motor vehicle having such battery

Abstract

The invention relates to a fastening anchor (1) for a battery (2) having a fastening anchor (1), a motor vehicle having the battery (2) and a method for producing the battery (2). The battery (2) has a battery cell arrangement (5), an electrically insulating carrier plate (3) and an electrically conductive cell contact plate (4). During the production of the battery (2), interstitial spaces (10) between the battery cells (6) of the battery cell arrangement (5) are filled with a liquid foam (11) hardened into a foam solid. The fastening anchor (1) has a head part (12) which is designed to be supported on a corresponding support surface (9) of the carrier plate (3). A pin portion (14) of the fastening anchor (1) is integrally bonded to the head portion (12), the pin portion (14) being designed to engage through the cell contact plate (4) and through the carrier plate (3) into one of the voids (10) between the battery cells (6). According to the invention, a form-fit structure (15) is formed on the outer side of the pin part (14), said form-fit structure being designed to provide a form-fit between the foam solid and the pin part (14) in such a way that, during the production of the battery (2), the liquid foam (11) lying directly against the form-fit structure (15) in the recess (10) is hardened.
