Latest Patents

Uchiyama’s listed patents address connections between ignition cables and spark plugs.

“Connecting Part for an Ignition Plug and Ignition Cable” describes a structure intended to secure a reliable electrical connection between the cable’s high-voltage terminal and the ignition plug’s end terminal. A ceramic plug tube holds two elastomeric bushings. The first bushing positions the ignition cable and its high-voltage terminal, while the second fits over the plug’s insulator. Together, these components help keep the terminals securely connected inside the tube.

“High Voltage Terminal for an Ignition Cable” focuses on positioning a spring inside a generally tubular terminal. The spring has enlarged portions at both ends, and a C-ring with projections helps hold one enlarged portion in place. This arrangement is designed to make the spring easier to install and position, supporting a reliable connection with a generally columnar ignition-plug terminal.
