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. The FuseSpecification defines the typical component attributes, i.e. the maximum electric current information for the fuse.

In addition to that the geometrical structure is described by a ConnectorHousingSpecification with it’s Slots and their Cavities (Cavity ). The PinComponents can be described in a more detailed way by usage of the PinComponentBehavior. Special information about the signal, signal direction or voltage can be placed here.

The PinComponent can reference a TerminalSpecification to define the physical properties of the pin. To avoid the confusion by too many crossing lines, the connection t the TermnalSpecification is not explicitly drawn in the diagram above.

Instantiating fuses

Instantiating fuses is like instantiating any other EE-Component. A EEComponentRole under a PartOccurrence references the FuseSpecification. The structure elements underneath are instantiated as far as they are relevant in the context (see Instantiation of Model Structures) and reference their corresponding part master element. For more information see E/E-Components.
