  • Patent number: 5416461
    Abstract: Disclosed is a fusible link which assures that a fuse element is completely and firmly received in a housing without any occurrence of incorrect contact of a male terminal with an opponent female terminal. Lances slantwise extending from a fuse element received in a housing are engaged with stepped engagement portions. While a cover is fitted to the housing, a plurality of projections extending from the cover are brought in contact with electrical contact portions of the fuse element so that the fuse element is firmly received in the housing at a predetermined position. Consequently, the fuse element is reliably received in the housing in the double engaged state without an occurrence of incorrect insertion of the fuse element.

  • Patent number: 4496929
    Abstract: An indicating fuse is provided with an indicator at the free end of a movable spring contact, the indicator being located at an angle with respect to the plane of the spring contact. Provision is made for lower rated fusing currents utilizing the same basic fuse structure by forming a slot in the flexible spring contact at the point of maximum bending. A rounded shoulder is formed on the fuse carrier body across which the spring contact member is bent to minimize breakage and damage. The flexible spring contact is integrally formed with a U-shaped terminal that mounts it on the fuse carrier body, a second substantially identical generally U-shaped terminal also being secured to the fuse carrier body to provide a fixed contact. Molded ribs are formed in the insulating material of the fuse carrier body adjacent the open ends of the U-shaped terminal members to prevent the terminals from pinching together to form an undesired tapered configuration.

  • Patent number: 4386335
    Abstract: An electric plug type fuse. The hollow glass body thereof contains a strip-like spring conductively connected to the bottom contact in the insulating tip of the fuse. Said spring is arcuate and has a center of curvature situated at the side of the spring where the longitudinal axis of the glass body is located. A solder joint preferable of a eutectic metal connects the end of the spring remote from the bottom contact to a fusible element capable of interrupting short-circuit-like currents, i.e. a ribbon type fusible element having at least one point of reduced cross-section. The aforementioned spring and the fusible element enclose an angle of approximately 90 deg. and the end of the fusible element remote from said spring is conductively connected to a screw shell. The spring puts the fusible element under tension and is released from it when the solder joint connecting both parts melts.

  • Patent number: 3984801
    Abstract: A fuse clip for cartridge type fuses which permits the insertion of a proper fuse while preventing the insertion of improper fuses. The clip permits the insertion of fuses having an annular groove around one of the end terminals while prohibiting the insertion of fuses without such annular groove. A main body member has a pair of flexible clamping arms which receive the cartridge-type fuse, and the clamping arms have aligned slots therein. A rejection member comprised of a C-shaped configuration, with inward extensions formed on the legs of the C, is inserted into the main body member, with the inward extensions extending through the slots of the clamping arms. The inward extensions are spaced apart a distance greater than the diameter of the annular groove, but less than the diameter of the remainder of the end terminal. The rejection member prevents the insertion of fuses unless an annular groove on the end portion is positioned between the two inward extensions.
