What is Hyperboloid Contact Technology?

Meet the Connector: Hyperboloid Contact Technology The hyperboloid contact was invented in 1956 by Francois Robert Bonhomme for railway applications. Connections for lighting and ventilation in train cars were not secure due to the high amount of shock and vibration, which caused frequent interruptions. In the 1960s, as the technology advanced and was patented, companiesRead More

Hyperboloid Contact Technology is Still Going Strong

From transportation to MIL/Aero to medical and more, hyperboloid contacts continue to be vital in the evolving world of electronics. Francois Robert Bonhomme invented the hyperboloid contact in 1956 in response to the need for more reliable connectors used in railway applications. By that time, rail systems had lighting and ventilation, but due to theRead More
