Title: Earl E. Masterson: Innovator in Connector Technology
Introduction
Earl E. Masterson is a notable inventor based in Minneapolis, MN, with a remarkable portfolio of six patents. His contributions to the field of engineering, particularly in connector technology, have made a significant impact on various industries.
Latest Patents
One of his latest inventions is the high-density coax connector. This innovative multi-pin coax connector assembly features connector housings made of metal or conductive plastic, which serve as a reference ground for all signals. The design includes passages extending through the connectors, with pin and socket terminals insert molded with insulating material. This configuration spaces the terminals from the conductive housing while providing air gaps along most of the length of the terminals. These air gaps, in conjunction with the insulating material, help achieve controlled impedance. As signals travel at high speeds along the terminals, they are bent to minimize signal reflection. Additionally, the connectors are equipped with power and ground busses on their outer surfaces, facilitating electrical connections between the respective busses of two connectors. A camming assembly means is also integrated, allowing for a positive wipe action as the terminals engage, which reduces the insertion force required.
