Specification for cavity seals that apply to more than one cavity. A CavitySeal is a water tight non-electrical object to fill a populated Cavity. MultiCavitySeals are formed to fit into one connector / slot and to seal more than one cavity at once.

There are existing two types of MultiCavitySeals:

  1. In first type the MultiCavitySeal has an opening for all cavities of the connector. Each opening can be filled either with a wire (without an individual seal) or with a CavityPlug (e.g. a synthetic pin) or a MultiCavityPlug.
  2. In the second type, the MultiCavitySeal has a specific configuration of openings for some cavities of the connector. These MultiCavitySeals are sealing all cavities with an opening and a wire in it and all cavities where no opening in the MultiCavitySeal exists. For each opening that has no wire it an additional CavityPlug is needed. 

The cavities that are left open by a MultiCavitySeal are defined with a SealedCavitiesAssignment.

Name Type Mult. Description Owning Classifier
identification String 1

Specifies a unique identification of the specification. The identification is guaranteed to be unique within the document containing the specification. Over all VEC-documents a Specification-instance can be trusted to be identical if the DocumentVersion-instance is the same (see DocumentVersion) and the identification of the Specification is the same.

description AbstractLocalizedString 0..*

Specifies additional, human readable information about the specification.

specialPartType String 0..1

The specialPartType allows the specification of subclassifications for a PartOrUsageRelatedSpecification (e.g. different types of connector housings).

cavityDiameter ValueRange 0..1

Specifies a range of valid cavity diameters to which the cavity seal fits.

hardness NumericalValue 0..1

Specifies the hardness of the cavity seal.

sealingClass SealingClass 0..*

Specifies the sealing class of the cavity seal.

geometry SealingGeometry 0..1

Defines the geometry of the cavity sealing.


This attribute is defined as an OpenEnumeration.

compatibleTerminalType TerminalType 0..*

Defines a list of terminal types that are compatible to this CavitySealSpecification. This defines as well the compatible cavities, since a plug is normally used when no terminals are present.

wireElementOutsideDiameter ValueRange 0..1

Specifies a range of valid wire diameters to which the cavity seal fits.

wireReceptionType WireReceptionType 0..1

Specifies the wireReceptionType to which the cavity seal fits. This should be an enumeration of values defined in a conformance class.
