Problems solved by technology

[0004] A disadvantage of the housings disclosed in the prior art or their production methods is that the currently known production methods often involve very high one-time outlays for molds and production facilities, especially when used in small series production
Furthermore, a large amount of material usage is required based on the manufacturing method, which leads to high production costs
In addition, the casings disclosed in the prior art have a large weight

Embodiment Construction

[0033] In the exemplary embodiment and the figures, identical or identically acting components can each have the same reference numerals. The shown elements and their dimensional ratios to one another are in principle not to be regarded as true to scale. On the contrary, some elements may be shown in bold or enlarged for better illustration and / or better understanding.

[0034] Figure 1A to Figure 1D A schematic illustration of a method for producing a housing component 1 that is shielded against electrical and / or magnetic radiation and has an environmental sealing function according to an exemplary embodiment is shown. In this case, in method step 1A, the metal shell 2 is produced by folding a metal sheet 20 . The metal sheet 20 may be a sheet cut from a sheet metal roll, for example by laser cutting, water jet cutting or stamping processes. The metal plate 20 may be, for example, a steel plate or an aluminum plate. After folding, the metal shell part 2 preferably has a ...

Abstract

The invention relates to a method for producing a housing component (1) with shielding from electrical and / or magnetic radiation, and with an environmental seal function, in which a metal housing part(2) is produced by folding a metal sheet. Furthermore, a synthetic shaped part (3) is produced by thermoforming such that the shape of the synthetic shaped part (3) matches the metal housing part (2), and the synthetic shaped part (3) is connected to the metal housing part (2). The invention also relates to a method for producing a high-voltage store, a housing component (1) with shielding from electrical and / or magnetic radiation, and a high-voltage store.

Description

technical field [0001] The invention relates to a method for producing a housing component with shielding against electrical and / or magnetic radiation and with environmental sealing, a method for producing a high-voltage energy store and a A housing component that shields / or shields against magnetic radiation and has an environmental sealing function, and a high-voltage battery. Background technique [0002] An electrical device may include an electrical device and a housing enclosing the electrical device for protection. In order to ensure the normal operation of the electrical device, in many electrical devices, the housing needs to shield the electromagnetic radiation to the electrical device on the one hand and satisfy the environmental sealing function on the other hand, such as preventing the intrusion of moisture and / or dust. Such an electrical system includes, for example, a high-voltage battery which is provided in a vehicle with an electric drive for supplying ele...
