Abstract
A washer to be arranged in a mechanical connection between an energy storage module and a housing of an electrical energy store for a motor vehicle includes an axial hole for receiving a connector and axially opposing bearing surfaces for pressing against metal contact surfaces of the energy storage module and the housing. The washer has a metal bushing for providing a current path between the contact surfaces for potential equalization between the energy storage module and the housing, the axially opposing faces of the bushing forming the bearing surfaces. The bushing has, between the faces, a tapering cross section forming a fuse for interrupting the current path in the event of overcurrent. A thermally insulating material surrounds the metal bushing at least in the region of the tapering cross section and compensates for the tapering cross section in order to provide a substantially constant outer diameter of the washer and to reduce the thermal conductivity of a heat-conducting path formed by the washer between the housing and the energy storage module.
