Re-pinning a crimped card-edge connector
Steps
- If any pin in a housing is bad, plan to replace every pin in it, one at a time so the order is kept.
- Push the extraction tool firmly into the gap between pin and housing, then pull the wire gently to free the pin.
- Cut the old pin off and strip 1/8 inch of insulation.
- Set the wire in a new pin so the front crimp tabs grip bare wire and the rear tabs grip insulation.
- Crimp the front section first, then the insulation section, and push the pin back into the housing.
