Abstract

The utility model discloses a plastic-sealed lead frame suitable for high-power electrical appliances, which is composed of a plurality of lead frame units in one row. The lead frame units are interconnected through a connecting rib. Each lead frame unit comprises a heat radiating fin and lead legs. The connecting parts between the heat radiating fin and the lead legs are bent. Seven lead legs are arranged. The width of each lead frame unit is 11.405+/-0.03mm. Each lead frame unit is provided with a positioning hole of which the diameter is 1.2+/-0.03mm. The thickness of the heat radiating fin is 1.3+/-0.015mm. The thickness of each lead leg is 0.45+/-0.01mm. The distance between the plane of the heat radiating fin and the plane of the lead legs is 2.67+/-0.05mm. Each heat radiating fin is provided with a heat radiating hole of which the diameter is 3.85+/-0.05mm. The plastic-sealed lead frame is a frame in which seven lead legs and a semi-packaging manner are adopted. The plastic-sealed lead frame is suitable for use in the large-power electrical appliances with small circuit board space.
