bend radius The bend radius is the minimum bend radius allowed for the bundle segment.
branch A set of bundle segments that share the same centerline.
bundle For electrical bundle: A document containing wires routed through geometrical bundles.
bundle segment A geometrical subdivision of a geometrical bundle.
It is the wire graphical representation in the digital mock-up. The bundle segment is created according to several rules:
  • The bend radius must be superior to half the diameter
  • In slack mode, an extra-length is added to the bundle segment calculated from a bend length percentage (Slack%).
  • The bend mode calculates the minimum length through all the constraint points, with regard to the minimum bend radius.
  • The length mode uses the length value: this value must be at least equal to the distance between the points.

Where the term single bundle segment occurs in this guide, it refers to a CATPart document created under the active product that contains just one bundle segment.

C

Top

connector An electrical component providing an electrical interface between two bundles, an item of equipment and a bundle or between wires. Comprises one or more electrical terminations. They are of two types: physical connector (from Electrical Library, Catalog or V4) and functional connector (from EFD application).

D

Top

diameter Corresponds to the wire diameter together with the insulation.
device Generic term for connector, equipment, shell, etc.

E

Top

effectivity A data fork of values in which an option is effective.
electrical bundle A document containing the wires routed through geometrical bundles.
electrical system An electrical unit which accomplishes a specific function. Consists of equipment, connectors and signals. Described in a CATProduct document.
electrical termination Electrical connection (often called pin) on a connector
equipment Electrical device comprising one or more associated connectors.

G

Top

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

H

Top

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

I

Top

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 when its reference doesn't out of this context.
As opposed, see reference.

M

Top

multi-branchable document A set of branches, themselves containing bundle segments, connected or not, composing the harness. It corresponds to a CATPart document.
See also single bundle segment document.

P

Top

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 bringing out a mechanical protection. It can be a sleeve, a corrugated tube, a taping, etc.

R

Top

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
    or,
  • A CATProduct document whose root product has electrical properties and exhibits electrical behavior.

See also instance.

routing An operation that computes the optimized wire route between two or more extremities of a signal.

S

Top

section Corresponds to the section of the wire together with the insulation.
segment Refers to bundle segments, whether grouped in branches in a multi-branchable document or created as single bundle segments in bundle segment documents.
single bundle segment document Corresponds to a CATPart document containing just one bundle segment.
See also multi-branchable document.
sleeve Can be of two types:
  • Conduit type: the wires are collected in a tube, flexible or not.
  • Jacket or sheath type: the wires are cased in the sleeve.

W

Top

wire Electrical wire: physical object corresponding to a signal
wire connection An electrical object linking two or more wires that share a common extremity
