Weidmuller Crimping Tools - Introduction
After stripping. appropriate contacts or wire end ferrules can be crimped to the end of the cable. Crimping produces a reliable connection between conductor and contact, and has more or less completely replaced soldering. Crimping describes the production of a uniform, nondetachable connection betweem conductor and connecting element. This should be achieved exclusively by the use of a high-quality precision tool. The result is a safe, reliable connection in both electrical and mechanical terms. Weidmuller Crimping Tools
Weidmuller offers a wide product range of mechanical crimping tools. An integral ratchet mechanism with disengaging option guarantees optimum processing quality. Crimp connections produced with Weidmuller tools comply with international standards and specifications.
Crimping of wire end ferrule: Optimum crimp of different cross-sections as an example:

Examples for the visual inspection of a crimp connection with manual and automatic crimping tools by Weidmuller: The conductor insulation must be pushed into the plastic collar. The ferrule sleeve must be completely filled by the conductor. Depending on the cross section, the conductor should protrude approx. 0...0.5 mm from the ferrule sleeve.
Crimping of Wire End Ferrules
Faulty crimping connections due to incorrect combination of cable and wire end ferrule:
It is not possible for a tool to function reliably with every combination of conductor and crimping material. It is possible that the stranded requirements for the crimped product can't be achieved, although taken on their own, both conductor and crimping material comply with the corresponding standard. The individual production tolerances of conductor and crimping material do not allow every conductor to be combined with every contact.
The combination of conductors, crimping material and crimping tool must be coordinated: this procedure is all the more difficult given the large number of products on the market. This means that the material must be defined and the crimping result tested, ensuring that the test, and later on the tool, satisfy the same conditions.
Faults which can occur during crimping:
Possible Ferrule Crimping Faults
  • Cracks along the sides and die impressions
  • Splitting of the ferrules
  • Asymmetrical crimping shape
  • Extreme burrs formed along the sides
  • Ferrule not filled by the conductor
  • Single conductors pushed back protruding from the collar
  • Single conductors squeezed off
  • Plastic collar damaged by the crimping jaw
  • Conductor insulation not pushed into the plastic collar
  • Ferrule bent longitudinally after crimping
