Crimp terminal

Crimp-cross section

A perfect crimp connection is gastight, therefore corrosion free which creates a cold weld of the parts being connected. For this reason, major features in achieving high quality crimp connections are the design of the contact and of course the crimping tool itself. Wires to be connected must be carefully matched with the correct size of crimp contacts. If these basic requirements are met, users will be assured of highly reliable connections with low contact resistance and high resistance to corrosion.

The economical and technical advantages are:

Constant contact resistance as a result of precisely repeated crimp connection quality
Corrosion free connections as a result of cold weld action
Pre-preparation of cable forms with crimp contacts fitted
More economic cable connection

Requirements for crimp connections are set in IEC 60352-2.

Pull out force of stranded wire

The main criterion by which to judge the quality of a crimp connector is the retention force achieved by the wire conductor in the terminal section of the contact. DIN IEC 60352, part 2, defines the extraction force in relation to the cross-section of the conductor. When fitted using HARTING crimping tools and subject to their utilization in an approved manner, our crimp connectors comply with the required extraction forces.
