Over-current protection device

Abstract

The present invention discloses an over-current protection device comprising at least one resistance component, outer conductive members and at least one insulation layer. The resistance component includes a current sensing element, a first conductive member and a second conductive member. The first conductive member is located on the surface of the current sensing element. The second conductive member is located on the other surface of the current sensing element. The resistance components that are adjacent use conductive buried holes to electrically connect their first conductive members and their second conductive member. The outer conductive member includes a first conductive end and a second conductive end. The first conductive end uses the conductive blind holes to electrically connect either the first or the second conductive member of the adjacent resistance component, and the second conductive end uses the conductive blind holes to electrically connect the other conductive member of the adjacent resistance component.
