A connection pole for an accumulator, wherein the connection pole includes an inner hollow region configured to receive a pole shaft of the accumulator. The connection pole includes ribs on its inner wall in the inner hollow region, wherein the ribs run in the longitudinal direction of the connection pole and one or more or all of the ribs are integrally formed with the connection pole from the material of the connection pole and protrude from the inner side of the connection pole such that the ribs form a gap between the pole shaft and the inner surface of the connection pole.

1. A connection pole for an accumulator, wherein the connection pole comprises an inner hollow region configured to receive a pole shaft of the accumulator, wherein the connection pole comprises a plurality of ribs on its inner wall in the inner hollow region, wherein the plurality of ribs run in the longitudinal direction of the connection pole and are tapered at a first end region and a second end region, wherein one or more or all of the plurality of ribs are integrally formed with the connection pole from the material of said connection pole and protrude from the inner side of the connection pole such that the ribs form a gap between the pole shaft and the inner surface of the connection pole, and wherein the material of said connection pole is a conductive material. 2. The connection pole according to claim 1, wherein the connection pole comprises an attachment section adapted for the attachment of the connection pole in a housing section of the accumulator and one or more or all of the ribs are arranged on the inner wall of said attachment section. 3. The connection pole according to claim 2, wherein the attachment section comprises a labyrinth section in which the outer circumference of the connection pole exhibits at least one circumferential projection, wherein the labyrinth section is designed to form a labyrinth with the housing material of the accumulator and one or more or all of the ribs are arranged on the inner wall of the labyrinth section. 4. The connection pole according to claim 1, wherein the one or more or all of the ribs are arranged in a section of the inner wall at which the inner wall is tapered in the direction of insertion of the pole shaft. 5. The connection pole according to claim 1, wherein the one or more or all of the ribs are designed as friction-reducing sliding elements between the connection pole and the pole shaft. 6. The connection pole according to claim 1, wherein the one or more or all of the ribs have their largest dimension in the longitudinal direction of the connection pole. 7. The connection pole according to claim 1, wherein the one or more or all of the ribs are evenly distributed over the inner circumference of the connection pole. 8. The connection pole according to claim 1, wherein the ribs extend upward toward a connecting section of the connection pole designed for the connection of a pole terminal without reaching said connecting section. 9. The connection pole according to claim 1, wherein the one or more or all of the ribs are rounded on their side facing the interior of the accumulator. 10. The connection pole according to claim 1, wherein the conductive material is lead. 11. A system, comprising: a connection pole for an accumulator, wherein the connection pole comprises an inner hollow region configured to receive a pole shaft of the accumulator, wherein the connection pole comprises a plurality of ribs on its inner wall in the inner hollow region, wherein the plurality of ribs run in the longitudinal direction of the connection pole and are tapered at a first end region and a second end region, wherein one or more or all of the plurality of ribs are integrally formed with the connection pole from the material of said connection pole and protrude from the inner side of the connection pole such that the ribs form a gap between the pole shaft and the inner surface of the connection pole, and wherein the material of said connection pole is a conductive material; andthe accumulator comprising at least one housing section, at least one electrode plate group inserted into the housing section, at least one pole shaft connected to the electrode plate group and a cover section in which at least one connection pole is integrated, wherein the pole shaft is led into or through an inner hollow region of the connection pole. 12. The system according to claim 11, wherein at no point does the pole shaft directly abut the inner side of the connection pole. 13. The accumulator according to claim 11, wherein the connection pole is embedded in a plastic material of the cover section, wherein the plastic material also at least partially covers the lower edge of the connection pole. 14. A system, comprising: a connection pole for an accumulator, wherein the connection pole comprises an inner hollow region configured to receive a pole shaft of the accumulator, wherein the connection pole comprises a plurality of ribs on its inner wall in the inner hollow region, wherein the plurality of ribs run in the longitudinal direction of the connection pole and are tapered at a first end region and a second end region, wherein one or more or all of the plurality of ribs are integrally formed with the connection pole from the material of said connection pole and protrude from the inner side of the connection pole such that the ribs form a gap between the pole shaft and the inner surface of the connection pole, and wherein the material of said connection pole is a conductive material; andwherein a leading end of the pole shaft when inserted or fed into the connection pole is of rounded configuration in the longitudinal direction of the pole shaft.
