Crimping wires — preparing connections for assembly

Crimping is the mechanical compression of a metal connector onto a suitably prepared wire end.

During crimping, the connector grips the wire core, creating a durable electrical and mechanical connection — without the need for soldering.

Correctly performed crimping ensures stable electrical contact, consistent connections and resistance to the wire pulling out of the connector.

The wire prepared in this way can then be used in the subsequent assembly of the device.

What to look out for when preparing wires

The description of crimping should be read alongside the illustrated wire preparation step. The quality of the finished connection depends on all the components being compatible, so check the requirements of the specific connector and tool before assembly.

• What wire cross-section and terminal type does the design specify?
• Are the tool and die intended for the selected connector?
• How should the connection be checked before further assembly?
