Device for making releasable contact with a battery cell

A device for detachable contact with a battery cell, having said device comprising:

• a cell receptacle having an opening facing a joining direction,
• said cell receptacle being delimited by a contact spring base from which contact tongues protrude in a direction opposite to the joining direction so as to form a jacket-side enclosure of the battery cell,
• wherein the contact tongues have contact bodies providing detachable engagement contact with the battery cell and protruding radially into the cell receptacle;
• wherein the surfaces of the contact bodies each have respective surfaces with a contact surface providing electrical contact with the battery cell;
• said surfaces of the contact bodies having a shape corresponding to a portion of an ovoid shape that is convex toward the cell receptacle, and wherein the surfaces extend away from the associated contact surfaces, curving away from the battery cell in all directions.
