Technical Information
• Crimp connection
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.
There are open crimp barrels (stamped contacts) and closed crimp
barrels (turned contacts).
The main advantages of crimp connections are:
• Efficient termination of contacts.
•Reproducible electrical and mechanical figures with
a constant crimp quality.
The requirements for crimp connections are defined
in DIN IEC 60352 Part 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.
Assembly instructions
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.
A detailed description of the crimp technology can be found in
our crimp tooling catalogs.
