4.1 Connection
Chapter navigation
Connection
The term connection is used for various meanings.
1. For a real connection of a line, for different media e.g. water, gas, electricity, at a connection point.
2. For the logical, symbolic connection of lines to drawing symbols in documentation.
This area is used for the general description of real connections.
A connection identifier is assigned to uniquely identify a real connection.
Each real connection must be described individually.
Recommendation for creation the connection identifier:
Unless you have an identifier specification from your design systems, the best way to number the connections of the equipment is as follows:
From top left to bottom left from left to right, from back to front (function related). Very often it happens in electrical engineering that several real connections are combined to one logical connection see examples:
Example circuit breaker logical 1 Connection 2 real connections Line and phase bridge connection with 1 actuation.
| Power contactor logical 1 connection 2 real line connections with 1 actuation.
|
Figure 46: CAx connection example real connection | Figure 47: CAx connection example real connection |
Figure 48: CAx connection example real connection
Auxiliary switch block: Screw connection Logical 1 connection 2 real connections with 1 actuation | Connection: Spring-cage connection Logical 1 connection 2 real connections with 2 actuations |
|
|
In the Functions section, the logical connections are then described according to their use in the CAE documentation and referenced to the connections described here in this block via the connection identifier.

Explanation of the position of the connection
The feature indicates the physical position (AXIS 1D Data Type) of the respective connection on the device and the direction from which the conductor is inserted.
The point is in the middle of the connector funnel opening and at the maximum rear point that the connector can reach. The point is specified in mm using the x/y/z-coordinates in relation to the reference point of the device. The alignment is described by an additional unit vector.
The Connection direction feature is intended for use in line routing. The connection direction indicates the preferred direction from which the conductor runs on the connection from the installation point of view. A standard preferred direction for normal use must be specified here.

Electrical connection points for real connections, bridges and accessories
- Electrical connection points for bar connection
- o for device screw connections for bars, cable lugs and conductor strips, the position of the connection is determined at the center of the screw connection at the level of the contact surface on the device.
Example:
Figure 50: CAx connection example connection point bars
- in the case of bridges/cross-connectors, test probes and similar accessories are maintained in the center of the contact hole. The corresponding contact point on the accessory is positioned so that the components fit together.
Example:
Figure 51: CAx connection example connection point Accessories
- Electrical connection point for bolt connection
- The point lies on the contact surface "down to center of the bolt". The corresponding contact point on the accessory is positioned so that the components fit together.
Example:
Figure 52: CAx connection example connection point bolt
- Electrical connection points of connectors, standard faces (M12, RJ45)
- The points are recorded on the middle of the front of the connectors. The corresponding point of the socket is recorded in such a way that the points match when assembled
Example:

Operating element of a connection
Mechanical actuation points for screws etc. are characterized by the features: Actuation vector
Tightening torque and output size described. Their physical position is displayed with the (AXIS 1D data type) and the direction with a unit vector.
- The points are recorded centrally on the contact surface between the actuating element and the tool.
- Example:
Figure 54: CAx connection Example of actuation point at the screw head
- If the point cannot be specified reliable due to the connection equipment or the delivery condition, the center must be specified from where a screwdriver has to move into the equipment in order to achieve the output of the screw head. The points are recorded centrally of the housing above the point of contact between the actuating element and the tool.
