Introduction

Pin Syuan Li is a notable inventor based in Hsinchu, Taiwan. He has made significant contributions to the field of electrical engineering, particularly in the development of innovative cable and over-current protection technologies. With a total of three patents to his name, his work reflects a commitment to enhancing safety and efficiency in electrical systems.

Latest Patents

One of his latest patents is a cable with over-temperature protection. This cable comprises a power conductor, a data conductor, and a first PTC device. The power conductor is designed to transmit electrical power between a source and a sink, while the data conductor transmits data. The first PTC device is coupled to the data conductor, and its resistance increases drastically to reduce current flow if the temperature exceeds a specified threshold. The first trip temperature is set between 55-80°C, with resistance values exceeding 20 kΩ at 85°C and 80 kΩ at 100°C. Importantly, the current flowing through the data conductor does not exceed 20 mA.

Another significant invention is an over-current protection device. This device includes a PTC device, first and second electrodes, and two welding metal plates. The PTC device consists of a first conductive layer, a second conductive layer, and a PTC polymeric material layer laminated in between. The first electrode connects to the first conductive layer, while the second electrode connects to the second conductive layer, remaining separated from the first. The welding metal plates are strategically placed at opposite ends of the device, designed to withstand spot-welding without damaging the PTC device.
