• Crimp connection
Assembly instructions
A crimp connection is a non-detachable electrical connection
between a wire and a crimp contact produced with the crimp
technology. Precise crimping dies which are matched to the
crimp barrel and the wire size and a defined deformation result
in a reliable electrical connection.
For crimp contacts use the released crimp tool.
The insertion and extraction of crimp contacts shall only be
approved with the corresponding insertion / extraction tool.
There are open crimp barrels (stamped contacts) and closed
crimp barrels (turned contacts).
A detailed description of the crimp technology can be
found in our crimp tooling catalogues.
Crimp contacts are in this catalogues on page 23/24.
• Efficient termination of contacts.
• Reproducible termination achieve consistent electrical
and mechanical results
The requirements for crimp connections are defined in
DIN EN 60352-2, IEC 60352-2.
An important point of the quality of a crimp connection is the
achieved tensile strength of the termination.
Easily measured, the tensile strength is a practible means for
quality control purposes.
Diagram 2 below shows the required minimum tensile strength for
open and closed barrels depending on the wire size.
