Instantiation

Component Description & Instantiation (Basics)

Specification of Parts Basic Component Description Many of the classes in the VEC are used for the defintion of the general properties of a component (Part Master Data). This is done with specifications (VEC Naming Convention “XXXSpecification”). A specification defines all properties of a component that are that are independant of a specific usage of the component (e.g. the number of cavities of connector or the cross section area of a wire).

Fuses

Fuses A single fuse is a two-terminal component that can be plugged or screwed into a compatible fuse slot. There are different types, which differ in their geometry, the type of connection, the tripping characteristics and their rated voltage. In VEC a fuse is handled as a EE-Component and that is why the FuseSpecification extends the EEComponentSpecification and describes it’s the available connector interface also with a HousingComponent and - in this case - with two PinComponents.

Multi Fuses

Multi Fuse Illustration A mutlifuse is a special type of fuse that combines multiple fuses in a single component (see Multi Fuse Illustration). In contrast to a regular fuse, where there are only two interchangeable pins, the multi fuse has a single dedicated supplying pin and multiple protected pins. An individual fuse component is located between each protected pin and the supplying pin. Each fuse component can have its own technical properties (e.

ECUs, EE-Components and Component Boxes

E/E components, represented in the VEC by the EEComponentSpecification and EEComponentRole, summarize all kinds of components with a more or less complex electrical function. In the VEC the description of an E/E component is a combination of the following (optional) aspects: Connector Interface / EE Component Header: Defines the properties and possibilities for a connection to a wiring harness or other e/e components. Internal Connectivity: Defines the electrical connectivity within a e/e component.
