What is crimping?

Crimping is a method of permanently joining wires/cables to connectors whereby the conductor is inserted into the barrel of the connector and then compressed about the wire to form a solid joint. Technically the two parts are deformed at such a high pressure that a cold flow of the material is accomplished, oxide layers are broken up and a high quality gas tight connection is obtained, the mechanical and electrical properties of which exceed those of the wire itself.

Optimal deformation is the compromise between electrical requirements against mechanical specifications. Our graph shows that the optimum crimp compression for many types of connectors lies between 10 and 20% of the initial cross-section. The amount and type of deformation must be engineered to provide the optimal electrical and mechanical characteristics required for a particular application.
