Title: Jun Shioya and a Fitting-Type Connection Terminal.

Introduction

Jun Shioya is an inventor associated with Nagoya, Japan. The available information credits her with 1 patent, concerning a fitting-type electrical connection terminal.

Latest Patents

Shioya’s patent, “Fitting-type connection terminal,” describes a design intended to reduce the force needed to insert one terminal into another while maintaining stable contact resistance. It uses tin films of specified thicknesses on the male and female terminals. By making the tin film thinner on one terminal, the underlying copper or copper-alloy material has a greater influence on the terminal’s apparent hardness, helping suppress adhesion between the tin films.

The patent states that this approach can reduce insertion force by more than 10% compared with a reference design using 1.0-micrometer tin films on both terminals. With a 0.1-micrometer film on the male terminal and a 0.3-to-1.0-micrometer film on the female terminal, the reduction can exceed 30%.

Career Highlights

The available details highlight Shioya’s contribution to electrical connector design, particularly the balance between easier terminal insertion and reliable electrical contact. No company affiliation is specified, so none is listed here.
