Power supply circuit`s electrical connection protecting device, has thermofusible wall melted to bring convex blade in electrical contact with convex blade of adjacent socket to cause dead short circuit when overheating occurs

摘要

The device has a connector (5) that is connected to a power supply circuit and in which a metal socket (10) has a convex blade (18) elastically contacting a thermofusible wall (20). The thermofusible wall is melted in order to bring the blade in electrical contact with a convex blade of an adjacent metal socket to cause a dead short circuit when overheating occurs.
