Quick Disconnect Connectivity

How Turck’s quick disconnect connectivity products helped the University of Wisconsin-Madison’s Electric Ford F150 research vehicle come to life

For his doctoral thesis in electrical engineering at the University of Wisconsin-Madison Phillip Kollmeyer developed and built an electric research vehicle. The postgraduate equipped a Ford F-150 with a modern battery pack, electric motor, and motor drive – including quick disconnect connectivity from Turck.

  • TURCK‘s quick-disconnect connectivity products allowed the quick and reliable connection

  • Research vehicle: With support from TURCK Phillip Kollmeyer developed an Electric Ford F150

The electrical engineer found support for his project at Orchid International, a metal stamping and manufacturing company, Orchid had been involved in building a prototype electric motor for a startup electric vehicle (EV) company, and expressed an interest in sponsoring a project with the university.

Orchid provided the foundation for the project – it designed and built a prototype electric motor, mounted the drivetrain, and also helped provide funds to ensure the extensive list of parts that were needed could be secured.

Strong support

Although Orchid provided strong support the postgraduate also took the project as an opportunity to collaborate with others. As Kollmeyer explained, “As the detailed plans were coming together, I realized I needed to find a way to connect all these systems together. At that time I remembered that Turck‘s range includes cabling“

Kollmeyer got in touch with Larry Jacob, Sr. Sales Engineer for Turck representative MTech, who was a key to the cabling and connectivity success of the project. As Kollmeyer describes, “I started out with an abstract block diagram of the whole vehicle, with lines connecting all the different components. Larry Jacob helped me get from the block diagram, to an actual specification for each cable in the vehicle. I really started out unfamiliar to the world of industrial cabling, and Mr. Jacobs met me personally, suggesting specific specialty cables for certain applications including Ethernet cable and power cables where they fit. Then I spent a long time with the big Turck connectivity catalog, and ended up with 34 cables providing interconnection between more than a dozen vehicle systems.”

Quick disconnect

One of the most convenient features of Turck’s cables is their quick disconnect feature – basically a few minutes is all that is needed to disconnect or reconnect a set of cables. With the research vehicle continuously having components and different systems worked on, there is a need to constantly remove and reinstall parts of the system. Turck’s quick disconnect connectors made what would otherwise be a major undertaking, one which for a vehicle typically involves a maze of hand assembled wire harnesses and comparatively fragile automotive connectors, a painless and easy part of the process.

Kollmeyer has taken full advantage of this feature to minimize the hours needed to complete the project. He explained the benefits as follows: “Many of the connections in our research vehicle are sensitive signal level cables, requiring shielded cabling. If I had to build all these cables by hand, it would have taken weeks, and I wouldn‘t be nearly as confident in their performance. And a further benefit of the Turck solution is the receptacles, which are populated with color coded flying leads making populating connectors quick and easy compared to traditional methods.”
