More efficient crimping: Twisted contacts on a strip as an alternative to the vibratory feeder

In automated cable assembly the reliable feeding of contacts plays a crucial role in efficiency and process reliability. Until now two common methods have been established for this purpose: the use of vibratory feeders and the processing of contact strips from a roll. When using so-called vibratory feeders, also known as vibratory pots, loose contacts are brought into a defined position by mechanical vibrations and then fed into the crimping process. This method is widely used but presents several challenges: the alignment of the contacts is prone to errors, and irregularities in the material flow can occur. An alternative is the feeding of pre-made contact strips. Here, the contacts are already arranged on a tape and continuously fed into the machine. This enables more consistent and better-controlled processing. To further increase processing efficiency, HARTING has developed a quick-change tool suitable for both semi-automatic and fully automatic crimping machines. This solution enables, for the first time, the processing of high-quality, turned Han® industrial connector contacts in tape-guided form. A special plastic band ensures secure fixation and precise positioning of the contacts throughout the entire process. This significantly reduces or completely eliminates manual intervention.

The advantages are clear:

  • Increased process reliability through stable contact guidance
  • Reduced cycle times through automated feeding
  • Less manual effort Consistent quality in the crimping process

Practical example: Implementation at ANZER Kabel

To demonstrate this innovative solution in a practical setting, HARTING partnered with us. The promotional video on the topic of "Contacts on a Tape" was produced at our Lemgo-Lieme site. One of our fully automated crimping machines was used.

The system impressively demonstrates how the new feeding technology can be integrated into existing production processes and what efficiency gains it unlocks. Processing twisted contacts on a tape represents a significant advancement in cable assembly.
Compared to conventional vibratory feeders, this technology offers not only greater process stability but also significant efficiency gains.
