- Basic
types
Basic connection types include translational types and rotational types.
Translational types affect translational degrees of freedom at both endpoints
of the wires to which the connector section is assigned and may affect
rotational degrees of freedom at the first or both endpoints of the wires.
Rotational types affect only rotational degrees of freedom at both endpoints of
the wires.
- Assembled
types
Assembled connection types are predefined combinations of basic connection
types. For example, a HINGE connection type combines a JOIN connection type (translational) and a REVOLUTE connection type (rotational) to join the position of two
points and provide a revolute constraint between their rotational degrees of
freedom.
- Complex
types
Complex connection types affect a combination of degrees of freedom in the
connection and cannot be combined with other connection types. They typically
model highly coupled physical connections.
- MPC types
MPC connection types are used to define
multi-point constraints between two points.
Note:
Abaqus/CAE
writes complete connector section data to the input file only when a connector
section has a connector section assignment in the model database. If you plan
to import a model from an input file and obtain connector sections, you must
make sure that all of the connector sections have assignments in the model
database.

Abaqus/CAE,

Understanding connector sections and functions.
For a description of each connection type and the equivalent basic connection
types that define the kinematic constraints of assembled type connections, see
