Note: There is a newer version of this specification see VEC 2.1.0

Specification for cavity seals that apply to more than one cavity. A CavitySeal is a watertight 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. For 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).

cavityDimension Size 0..*

Specifies a valid cavity dimensions to which the cavity part fits. The dimension defines the size of the sealing area of the cavity (crimp end), not in the contacting area (box end).

Note: CavityDimension is of type Size which is defined as x & y with type NumericalValue. NumericalValue can define tolerances. So, a cavity dimension is not necessarily a single fixed value.

hardness NumericalValue 0..1

Specifies the hardness 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.

compatibleCavityGeometry CavityGeometry 0..*

Defines a list of CavityGeometries that are compatible with this cavity part.

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.

insideDiameter NumericalValue 0..1

Defines the inside diameter in the relaxed state for a cavity seal.
