The Flattening Degree Of The Metal Sleeve Crimped By The Cold Press Needle Crimper Should Be Moderate.

When using contact crimper, the degree of flattening of the metal sleeve directly affects the crimping quality. If the sleeve is flattened too lightly, the stranded wires may not be fully secured, resulting in poor contact or loosening. If the flattening is too excessive, it will damage the sleeve's metal structure, affecting the electrical contact and mechanical strength between the wire and the sleeve metal.

Appropriate flattening requires the sleeve wall thickness and length to match the wire cross-sectional area, and the sleeve to deform evenly using d sub contact crimper. This ensures the stranded wires are tightly wrapped within the sleeve, guaranteeing mechanical fixation and conductivity. Most professional connector manufacturers require strict adherence to the corresponding wire gauge when selecting sleeve specifications.

Inspections after contact crimping tool crimping include: verifying wire strength through a tensile test; observing the sleeve for cracks or uneven deformation; and confirming that the wire insulation layer is undamaged after crimping. If the flattening is uniform and there is no structural damage, the crimping process has achieved an ideal state.
