Patent ID: 7052332

Claim:
A connecting pole for an accumulator, the connecting pole being electrically connected to a cell connector and an electrical conductor, the connecting pole comprising: a pole sleeve, the pole sleeve adapted to be inserted in a sealed manner into a plastic housing part of a housing of the accumulator, the pole sleeve electrically contacts the cell connector; a first contact-making element being firmly connected to the circumference of the pole sleeve, by a connecting layer formed by one of the processes selected from the group consisting of bonding, soldering, and welding, the connecting layer being located between an inner surface of the first contact-making element and an outer surface of the pole sleeve, the first contact-making element being composed of a mechanically harder material than the material of the pole sleeve; the pole sleeve comprising an axial pole sleeve extension, and wherein the first contact-making element is in the form of a contact-making sleeve which is attached to the outside of the pole sleeve or to the axial pole sleeve extension; and a second contact-making element which is conductively connected to the electrical conductor, the first contact-making sleeve making electrical contact on an outer surface with the second contact-making element.
