MultiCavitySealSpecification
Was replaced by the more powerful concept of CableSeals (see documentation of MultiCavitySealSpecification).
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 two types of MultiCavitySeals:
- 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.
- 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.
Note: With Version 2.2.0 The MultiCavitySealSpecification (and all associated concepts like the MultiCavityPlugSpecification and the corresponding Roles) has been replaced by the CableSealSpecification. The MultiCavitySeal(Specification) has multiple design flaws that became obvious, when more complex connector assemblies were taken into account (e.g. modern high-voltage or high-frequency connector systems). The main reason for deprecation of this concept were:
- The MultiCavitySealSpecification inherits from CavitySealSpecification. Therefore, all openings in a MultiCavitySeal have to share the same properties.
- A ContactPoint is required to introduce an occurrence of a MultiCavitySeal. However, such seals are often placed at certain position on the wire and are not associated directly with specific ContactPoint. They also might be used on multi-core wires before those are split up into individual wire elements (that are contracted individually).
- It is not possible to assign a wire to a specific opening in the seal, which means an incomplete product definition.
- Such seals are often used in addition to a conventional cavity seal. However, the ContactPoint only permits one CavitySeal per contacting situation. This is true for conventional cavity seals that are associated with a specific crimp. This is not true for cable seals where multiple seals can be added to the wire.

Attributes
| 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. | Specification |
| description | AbstractLocalizedString | 0..* | Specifies additional, human readable information about the specification. | Specification |
| specialPartType | String | 0..1 | The specialPartType allows the specification of subclassifications for a PartOrUsageRelatedSpecification (e.g. different types of connector housings). | PartOrUsageRelatedSpecification |
| cavityDimension | Size | 0..* | Specifies a valid cavity dimension 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. | CavityPartSpecification |
| hardness | NumericalValue | 0..1 | Specifies the hardness of the cavity seal. | CavityPartSpecification |
| geometry | SealingGeometry | 0..1 | Defines the geometry of the cavity sealing.
This attribute is defined as an OpenEnumeration. | CavityPartSpecification |
| compatibleTerminalType | TerminalType | 0..* | Defines a list of terminal types that are compatible to this CavitySealSpecification. This defines the compatible cavities as well, since a plug is normally used when no terminals are present. | CavityPartSpecification |
| compatibleCavityGeometry | CavityGeometry | 0..* | Defines a list of CavityGeometries that are compatible with this cavity part. | CavityPartSpecification |
| wireElementOutsideDiameter | ValueRange | 0..1 | Specifies a range of valid wire diameters to which the cavity seal fits. | CavitySealSpecification |
| wireReceptionType | WireReceptionType | 0..1 | Specifies the wireReceptionType to which the cavity seal fits. | CavitySealSpecification |
| insideDiameter | NumericalValue | 0..1 | Defines the inside diameter in the relaxed state for a cavity seal. | CavitySealSpecification |
