Crimping Tools
Stripping, Crimping and Cable Processing
Crimping tools produce the solderless connection between conductor and contact described in DIN EN 60352-2. The quality of the joint depends on crimp height and crimp width; it is verified on the micrograph of the cross section and by pull out force. A ratchet lock prevents the tool from opening before the pressing cycle is complete and keeps the result repeatable across a whole batch. The tools process wire end ferrules to DIN 46228 and cable lugs to DIN 46234 and DIN 46235, plus the common plug contact systems. The range covers 209 articles, with Knipex, Weidmüller, C.K, Wiha, Bernstein and Bahco as the leading brands.
| Crimp profile | Contact type | Cross section range | Characteristic |
|---|---|---|---|
| Square crimp | wire end ferrules to DIN 46228 | 0,25-2,5 mm² | centred compression by four jaws |
| Hexagonal crimp | wire end ferrules, including large sizes | 0,08-16 mm² | even compaction of the strands |
| Trapezoidal crimp | wire end ferrules, twin ferrules | 0,5-16 mm² | standard in terminal wiring |
| Roll crimp | insulated cable lugs and connectors | 0,5-6 mm² | insulating sleeve is pressed as well |
| Indent crimp | cable lugs to DIN 46234 and DIN 46235 | up to 25 mm² | single indent into the barrel |
| System crimp with exchangeable die | D-Sub, coax, modular, blade terminals | per die | one base tool for several contact systems |
Typical applications: terminal wiring in control cabinets using wire end ferrules; wiring harnesses and connector assembly in electronics manufacturing; terminal blocks and distribution boards with cable lugs; network and coaxial work with modular and BNC connectors; test field and prototype build with changing contact systems; maintenance and service cases with VDE requirements.
