The invention relates to a sealing plug arrangement (1, 2) for a battery, wherein the sealing plug arrangement comprises at least one plug part (1) and a plug retainer (2), and the plug retainer (2) has a hollow area (4) for accommodating at least one retaining section of the plug part (1), wherein the plug part (1) is designed to seal off at least one interior (73, 74) of the battery from the environment when the plug part is installed in the hollow area (4) of the plug retainer (2). Proceeding from this, an improved sealing plug arrangement is specified that can be realized at low cost and that is reliable. For this purpose, the plug retainer (2) comprises at least one flow channel (6) on the inside of the plug retainer in the hollow area (4), which flow channel extends at least along the area in which the plug part (1) is retained in the plug retainer (2) when the plug part is installed in the hollow area (4).

1. A sealing plug arrangement (1, 2) for a rechargeable battery, with the sealing plug arrangement having at least a plug part (1) and a plug holder (2), the plug holder (2) having a hollow region (4) for accommodating at least one holding section (5) of the plug part (1), with the plug part (1) being designed to seal off at least one interior (73, 74) of the rechargeable battery from the surrounding area when said plug part is fitted in the hollow region (4) of the plug holder (2), characterized in that the plug holder (2) has at least one flow channel (6) on its inner circumferential surface in the hollow region (4), said flow channel being arranged between the outer circumferential surface of the at least one holding section (5) of the plug part (1) and the inner circumferential surface of the plug holder (2) and extending at least along that region in which the plug part (1) is held in the plug holder (2) when said plug part is fitted in the hollow region (4) wherein the plug part (1) has a cutout (12) on its upper face in the region of an overpressure prevention region (7), opposite from the holding section (5). 2. The sealing plug arrangement as claimed in claim 1, characterized in that the flow channel (6) extends as far as the overpressure safety region (7). 3. The sealing plug arrangement as claimed in claim 1 or 2, characterized in that the plug part (1) has a collar (9) which forms a stop when the plug part (1) is inserted into the plug holder (2). 4. The sealing plug arrangement as claimed in claim 3, characterized in that the collar (9) has a sealing bead (10) which faces in the direction of the plug holder (2) when the plug part (1) is inserted into the plug holder (2), the intention being for said sealing bead to butt against a sealing surface (11) of the plug holder (2). 5. The sealing plug arrangement as claimed in claim 1, characterized in that the cutout (12) has a substantially linear contour or a contour which is substantially in the form of part of a circle when the plug part (1) is viewed from above. 6. The sealing plug arrangement as claimed in claim 1, characterized in that the plug part (1) has a point (13) of increased flexibility in the region of the overpressure prevention region (7). 7. The sealing plug arrangement as claimed in claim 1, characterized in that the plug part (1) is composed at least partly of elastomeric material. 8. The sealing plug arrangement as claimed in claim 1, characterized in that the plug holder (2) has a plurality of flow channels (6) on its inner face in the hollow region (4). 9. The sealing plug arrangement as claimed in claim 1, characterized in that the effective inside diameter of the hollow region (4) is larger than the outside diameter of the holding section (5). 10. The sealing plug arrangement as claimed in claim 1, characterized in that the plug holder (2) has protruding centering elements (14), which are arranged on ribs (16) which are formed between the flow channels (6), on its inner face in the hollow region (4). 11. The sealing plug arrangement as claimed in claim 1, characterized in that a mating bearing device (69) is provided, said mating bearing device fixing the plug part (1) in its position relative to the plug holder (2) in the axial direction in the state in which said plug part is mounted on the plug holder (2). 12. The sealing plug arrangement as claimed in claim 1, characterized in that a plug accommodation element (60) is provided, said plug accommodation element having an inner chamber (65) for accommodating the plug part (1) and the plug holder (2), and being provided with a holding means (64) in order to be fastened to the housing (71). 13. The sealing plug arrangement as claimed in claim 12, characterized in that the plug accommodation element (60) has the mating bearing device (69). 14. A rechargeable battery having a sealing plug arrangement (1, 2) as claimed in claim 1.
