Latest Patents

**Terminal Insertion Apparatus.** This apparatus holds two terminal-equipped wires and a connector housing with holes for receiving the terminals. Its insertion head uses two movable holders, each with inner and outer grips, to position and guide a wire toward the connector. The holders move vertically and horizontally, supporting controlled terminal insertion.

**Sealing Member Fitting Apparatus.** This apparatus transfers a hollow sealing member from a receiving position to a fitting position, where it is placed on the covered end of an electrical wire. A sliding insertion guide helps align the wire’s covering end with the sealing member, positioning their central axes substantially coaxially.

Career Highlights

Nakajima’s listed inventions address practical stages of electrical-wire assembly: inserting terminals into connector housings and fitting seals onto wire ends.
