Abstract: A lead frame for an optocoupler is provided, which is a metal sheet and includes multiple frame units and multiple mutually parallel connecting strips. The frame units are arranged at intervals on each of the connecting strips. Each of the frame units includes two adjacent functional parts, and two pins perpendicularly connected to the connecting strip. The two functional parts are both located on one side of the connecting strip and are respectively connected to the two pins and ends of the two pins are located on the other side of the connecting strip. The area of each of the functional parts is sufficient to accommodate a chip to be installed and fixed, and the chip is any one of a light-emitting chip and a light-sensing chip.
