Title: Leonard A Johnson: Innovator in High Voltage Insulation and Fiber Optics

Introduction

Leonard A Johnson, a prolific inventor based in Austin, Texas, has made significant contributions to the field of electrical insulation and fiber optics. With a total of four patents to his name, Johnson's work focuses on innovative solutions that enhance the performance and reliability of optical fiber technologies.

Latest Patents

Among Johnson's latest patents is the design for a high voltage insulator for optical fibers. This invention features an insulative support rod that is wrapped with at least one optical fiber. It is covered by an outer elastomeric skirted insulative sleeve that securely squeezes the optical fiber against the support rod. To ensure a void-free bond, a dielectric sealant—such as silicone gel—is applied along the optical fiber, filling any adjacent voids. Additionally, the elastomeric outer sleeve acts as a resilient barrier against moisture. In an enhanced version, an inner layer of elastomeric material is integrated between the support rod and the optical fiber to provide further cushioning and minimize void size.

Another notable invention by Johnson is an annealing mold and retainer for making fiber optic current sensors. This device consists of a fiber holding plate equipped with channels for the fibers and an annealing insert. Retainers are used to keep the fibers secured in the channels during the annealing process. Afterward, the annealing insert is exchanged for a packaging insert. The fiber holding plate is designed to fit between a support plate and a cover plate, both of which feature a coextensive current conductor port, mounted within a housing that includes vibration mounts to protect the integrity of the components.
