Pull-out force

The pull-out force is the force which is required to pull the crimped conductor out of the connector.

The insulation support is thus rendered useless. In addition to the primary test of the crimp level and thus the correct compression of the conductor, the measurement of the pull-out force represents a supplementary test. It provides information on the mechanical strength and holding force of the conductor crimp.

A crimp test solely on the basis of hte pull-out force will not provide reliable information on the required dense compression.

The pull-out force is defined in a standard relative to the cross-section of the conductor and represents a minimum value which msut be satisfied by the correct dimensions of the crimp sleeve and the correct compression of the conductor.

Manuel pliers with crimp sections for all conductor cross-sections provide the best guarantee of this.
