Abstract

A container for a portable, rechargeable direct current storage device, having the following features: a housing with a housing underside with a housing set-down surface, a housing upper side, housing side walls and a housing interior, and also electrical anode and cathode contacts, wherein the housing underside has formed in it, on mutually opposite edges, set-back guide means, which extend in the direction of the housing upper side from a set-down plane defined by the housing set-down surface. The anode contact and the cathode contact can be arranged on the housing, in one or more of the set-back guide means, at a distance of at least five millimeters from the set-down plane, wherein that region of the respective housing side wall which is adjacent to the anode contact and the cathode contact terminates at a distance of at least five millimeters from the set-down plane.

Claims

1. A container for a hand-portable, rechargeable direct current storage device, comprising:

a housing provided with a housing underside with a housing set-down surface, a housing upper side, housing side walls and a housing interior,

an electrical anode contact and

an electrical cathode contact,

wherein the housing underside has configured upon it, on mutually opposite edges, set-back guides which extend in the direction of the housing upper side from a set-down plane defined by the housing set-down surface,

wherein the anode contact and the cathode contact in one or more of the set-back guides are arranged on the housing at a distance of at least five millimeters from the set-down plane, whereby that region of the respective housing side wall which is adjacent to the anode contact and the cathode contact terminates at a distance of at least five millimeters from the set-down plane, wherein the housing underside, considered from the housing set-down surface, is provided with a stepped surface profile section, at least at the periphery of the housing, whereby said stepped surface profile section which, accordingly, is removed from the set-down plane, is not limited laterally by housing side wall segments such that, even when the container is set down on sludge, adhesion of dirt which penetrates to those regions of the housing underside which are recessed in this stepped arrangement is inhibited.

2. The container as claimed in claim 1, wherein the housing underside, in the region between the set-back guides configured on the opposite edges of the housing, terminates at a distance of at least five millimeters from the set-down plane.

3. The container as claimed in claim 1, wherein the set-back guides are provided with central cut-outs, which are arranged adjacently to the anode contact and/or to the cathode contact.

4. The container as claimed in claim 3, wherein in a view of the housing underside, the central cut-outs adjacently to the anode contact show a different cross-sectional profile to the central cut-outs adjacently to the cathode contact.

5. The container as claimed in claim 3, wherein the central cut-outs extend at least partially beyond the anode contact and/or the cathode contact in the direction of the housing upper side.

6. The container as claimed in claim 1, wherein the set-back guides are configured, at least partially, as recesses in the housing side walls.

7. The container as claimed in claim 1, wherein the anode contact and the cathode contact are arranged in mutually opposing set-back guides.

8. The container as claimed in claim 1, wherein the housing underside is provided with an anode opening and a cathode opening whereby, from the anode opening through to the anode contact, a section of one of the set-back guides is configured as an anode guide channel with an anode guide channel recess, and

from the cathode opening through to the cathode contact, a section of one of the set-back guides is configured as a cathode guide channel with a cathode guide channel recess.

9. The container as claimed in claim 7, wherein the anode guide channel and/or the cathode guide channel are arranged adjacently to one of the four housing side walls, and extend along the housing side walls.

10. The container as claimed in claim 9, wherein the anode contact and the cathode contact are arranged inside the respective guide channel and/or on the housing side walls, such that there is a maximum clearance between the anode contact and the cathode contact.

11. The container as claimed in claim 8, wherein the anode opening and the cathode opening are configured with different opening profiles.

12. The container as claimed in claim 8, wherein the anode guide channel and/or the cathode guide channel are hermetically sealed in relation to the housing interior.

13. The container as claimed in claim 1, wherein the anode contact and/or the cathode contact are covered by mechanically pivoting cover devices.

14. The container as claimed in claim 1, wherein adjacently to the set-back guides and/or within the set-back guides, air-conditioning interfaces are provided for the air-conditioning of the housing interior.

15. The container as claimed in claim 1, further comprising a connecting device for the electrical bonding of the anode contact and the cathode contact of the container upon the fitting of the container to the connecting device.
