Crimping Presentation

  1. 1. CRIMPING A guide to good crimping practices & procedures .
  2. 2. WHAT IS A CRIMP ? <ul><li>Crimping is a process where a cable is stripped, & the strands of wire are placed into a metal terminal. The terminal is then squeezed around the wire strands to ensure that : </li></ul><ul><li>A : the wire is securely held by the terminal </li></ul><ul><li>B : there is good electrical contact between the terminal & the wire . </li></ul>
  3. 3. CRIMPING – WHY CRIMP ? <ul><li>It is quick </li></ul><ul><li>It is cheap </li></ul><ul><li>It is durable & reliable if done properly </li></ul><ul><li>It does not need any extra material </li></ul><ul><li>It produces good electrical contact between a wire & a terminal . </li></ul>
  4. 4. CRIMPING AGENDA <ul><li>Wire stripping </li></ul><ul><li>Features of a good crimp </li></ul><ul><li>Crimping details </li></ul><ul><li>Pull testing, crimping of marriages </li></ul><ul><li>Crimp measurement </li></ul><ul><li>Crimped wire / terminals </li></ul><ul><li>Crimping tool </li></ul><ul><li>Crimp & terminal faults – terminal checks . </li></ul>
  5. 5. Wire stripping (1/2) <ul><li>The stripping blades are too loose : the insulation is torn, instead of cut </li></ul><ul><li>The stripping blades are too close together : the strands are scratched/cut or missing . </li></ul>
  6. 6. Wire stripping (2/2) <ul><li>The stripping blades are out of alignment </li></ul><ul><li>Good stripping . </li></ul>
  7. 7. Features of a good crimp (1/2) Copper wings Insulation wings
  8. 8. Features of a good crimp (2/2) 'F' crimp Wrap around crimp
  9. 9. Crimping details Copper crimp Ins. crimp
  10. 10. Pull testing
  11. 11. Crimping of marriages <ul><li>For wires of different sizes, the smaller wire should be on the bottom of the crimp </li></ul><ul><li>For wires of equal size, the wires may be side by side or top & bottom </li></ul><ul><li>When pull testing marriages, only the smaller wire should be held in the machine & the specification for the smaller wire only should be used . </li></ul>
