Definitions

  • This invention relates to a metal housing for an electrical component, and is more particularly concerned with metal housings for electrical components wherein the housings undergo a structural change upon a buildup of gas therein to lo SUMMARY OF THE INVENTION
  • a metal housing having corrugations and effective to operate a disconnect fuse upon an internal pressure buildup is provided as a fluid-tight structure both before and after operation of the fuse.
  • the housing includes a can-type structure, preferably of aluminum.
  • the cover may be metal or a ceramic material having a metal periphery for welding to the remainder of the housing.
  • the electrical component is illustrated as having had the fuse operated.
  • the fuse may be provided as a weakened point in one of the connecting wires 1 of an oil-impregnated regenerable electrical capacitor coil 5 which is mounted in a can-type housing 4 so that the lower end of the wire I is substantially fixed in relation to the housing 4.
  • the connecting wire I is guided through a sealed insulating member 2 in the cover 3 to the exterior of the device.
  • the cover 3 is welded to the upper edge of the housing 4, to provide a fluid-tight seal.
  • the upper edge of the housing may, as shown in the drawing, embrace the cover or the cover may have at its lower edge a peripheral groove into which the housing edge is inserted and sealed.
  • the housing 4 is provided with at least one corrugation 6 which by elongation due to the buildup of gas above maximum admissable internal pressure causes separation of the fuse, in this case wire 1.
  • the housing and the cover are made of aluminum.
  • the cover also may be made of insulating material, such as a ceramic, whereby the outer edge of the material carries a metal ring sealed thereto.
  • insulating material such as a ceramic
  • cup portion is metal and at least the periphery of the cover portion is metal and said means for providing a fluid-tight seal comprises a weld.
