| 摘要 |
The invention relates to a voltage supply device, particularly for a motor vehicle, comprising a housing (10) for receiving at least one energy storage module (40) and/or another, in particular, voltage-conducting component, said energy storage module (40) and/or other component being fixed, on the housing interior side, to a housing surface (11). The housing (10) is formed from a first material. The screw connection is formed by a press-fit bolt (20, 30) which consists of a second material and which has at least one connecting section (22, 32) and one fixing section (21, 31) that comprises an outer thread. Said press-fit bolt (20, 30) is inserted through an associated recess (13, 14), from outside of the housing surface (11) and with the fixing section (21, 31) at the front, and pressed, in the region of the connecting section (22, 32), to the material of the housing surface (11) such that a sealing contact surface of the connecting partners results which has minimal transfer resistance. In addition, the energy storage module (40) and/or the other voltage-conducting component is fixed to the housing surface (11) by means of a nut (45) screwed onto the connecting section (22, 32). |
