back shell Designates the outer casing. An electrical component used to guide the ends of wires and to protect the crimping area.
back shell connection
Sub-element allowing a connection with another back shell connection point.
bend radius The smallest radius that a bundle segment can be bent before causing permanent damage to the bundle segment: it corresponds to the maximum torsion that can be applied to a wire depending on its physical characteristics.
bundle Always refers to an electrical bundle.
bundle segment A geometrical subdivision of a bundle, also called segment or BNS in V4 environment.
bundle connection
Sub-element used to attach the end of a bundle segment to an electrical component (except filler plugs and internal splices).



cavity Sub-element used to specify the location of an electrical object when making an electrical connection. An electrical connection can be defined between a cavity and a cavity connection point.
cavity connection
Sub-element used to specify how a device is placed in a cavity when making an electrical connection. This connection corresponds to an assembly relation.
connect Establishes a specific relationship between two electrical objects:
  • Electrical signal continuity is ensured between the connected components.
  • If connection points have been defined, mechanical assembly constraints are automatically created.
connector Basic term grouping seven connector types, each having specific capabilities: single insert connector, multi-insert connector, stud, external slice, terminal strip, terminal block, and internal splice.
connector connection
Sub-element used to specify how mating connectors are placed when making an electrical connection.
contact Electrical component used within a termination and a cavity or between bundle segments.
into electrical device
Operation adding electrical behavior to an existing component which becomes an electrical component. If the component is a reference, it becomes an electrical reference. Converting an instance adds electrical behavior to the instance only; it does not modify the reference.
csv file A text file used for data exchange between CATIA V4 and V5



disconnect Deletes the electrical connection between two electrical components.



electrical behavior Specific behavior (rules and properties adapted to the electrical domain) of a component when defined as an electrical device.
electrical bundle A document containing the wires routed through geometrical bundles.
electrical component A product or a part with electrical behavior.
electrical connection Relationship existing between two electrical objects. Allows connection relations as well as assembly constraints.
electrical system An electrical unit which accomplishes a specific function. Consists of equipment, connectors and signals. Described in a CATProduct document.
equipment An electrical component used to assemble mounting equipment, bundle segments, connector shells, single insert connectors, studs, terminal blocks, terminal strips, contacts and filler plugs.
external splice Electrical connector used to secure bundle segments from different geometrical bundles.



filler plug Electrical component used to seal an unused cavity.



geometrical bundle A document containing an assembly of connectors, supports and insulation, as well as the geometric representation of a harness.



harness An assembly of wires, connectors, supports and insulation manufactured together. Represented in CATIA by both geometrical and electrical bundles.



instance Designation of reference placed in a context, i.e. in design mode. An instance can have additional characteristics that do not belong to the reference. For example, the instance of a wire has a length attribute in an assembly context whereas the corresponding reference does not.
As opposed, see reference.
internal splice Electrical connector used to secure wires belonging to the same bundle segment together.



mapping An operation that consists in assigning electrical device attributes to corresponding keywords in catalog chapters.
mounting equipment A non electrical part used to assemble several components.



pin An electrical termination
properties Attributes of a component that define its electrical, mechanical, etc. characteristics.
protective covering Covering element wrapping the conductor and possibly the insulating coating offering mechanical protection. It can be a sleeve, a corrugated tube, a tape, etc.



realize An operation that links a physical device to a functional definition or vice-versa.
reference Describes a real object. A reference can be stored in a catalog. In the electrical context, a reference corresponds either to:
  • A CATPart document which has electrical properties and exhibits electrical behavior
  • A CATProduct document whose root product has electrical properties and exhibits electrical behavior.

See also instance.

retainer A special type of support comprising a flat base. The bundle segment routed through this support keeps in contact with this base, whatever the bundle segment diameter.



segment See bundle segment.
shell A non-electrical device which groups one or more electrical connector parts.
Also called connector shell.
signal A logical connection between two or more components. May be of the following types: ground, shielding, video, power, command or grouped.
single insert connector Male or female electrical connector.
store (a device) Place an electrical component in a catalog.
stud Electrical connector used to secure bundle segments and ground both bundle segments or items of equipment.
support A mechanical object used to hold bundle segments in position.



terminal block Electrical connector used to secure bundle segments.
terminal strip Electrical connector comprising a strip of terminations used to secure bundle segments.
termination Sub-element ensuring electrical signal continuity between any type of electrical component except filler plugs. It cannot be dissociated from the electrical component and corresponds to a contact crimped into a cavity.
Also called pin.



wire Electrical wire: physical object corresponding to a signal. Several wires can correspond to a signal.
A wire reference is characterized by properties such as: section, diameter, bend radius, color, linear mass, etc.
wire group An electrical object representing a multi-conductor cable, for example a twisted pair. Wires in a group are routed together.
