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 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.

Relays A relay is a component for switching current loads. Unlike fuses, there are more than one input pin and one output pin (number of pins >3). Some components, referred to as relays, are in reality small controllers with up to 17 pins. In the VEC schema a relay is a special type of an EE-Component. It also owns a HousingComponent with it’s PinComponents underneath where these HousingComponent can be defined more detailed with a ConnectorHousingSpecification and the PinComponents with a referenced TerminalSpecification.

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.
