Abstract

The invention relates to a high-voltage component (18, 20, 22, 24, 26, 28) for arrangement in a high-voltage on-board electrical system (16) of a motor vehicle (10), comprising a housing (30) and a protective cover (32) which at least partially encloses the housing (30). The protective cover (32) comprises a textile surface texture with high tensile strength fibers. The protective cover (32) has afurther surface texture that is connected to the textile surface texture. The further surface structure has a thermoplastic material which can expand in a heated state. In the expanded and cooled state of the thermoplastic material, the shrinkage of the thermoplastic material is caused by applying heat to the thermoplastic material. The invention also relates to a motor vehicle (10) having at least one such high-voltage component (18, 20, 22, 24, 26, 28) and to a method for protecting a high-voltage component (18, 20, 22, 24, 26, 28).

Description

technical field [0001] The invention relates to a high-voltage component for being arranged in a high-voltage on-board electrical system of a motor vehicle, the high-voltage component having a housing and a protective cover which at least partially surrounds the housing. Cover includes woven surface texture / fabric with high tensile strength fibers The invention also relates to a motor vehicle comprising at least one such high-voltage component and a method for protecting the high-voltage component. Background technique [0002] Document DE 198 38 422 A1 describes a high-power semiconductor module having a housing which surrounds semiconductor components. In order to prevent flying fragments in the event of a module explosion, the module has a protective cover which surrounds the housing and is made, for example, of Kevlar. [0003] In motor vehicles, lines that are subject to high loads, such as the lines of the high-voltage on-board power system or cooling water hoses, a...
