US Patent:

41796780, Dec 18, 1979

Filed:

Apr 7, 1978

Appl. No.:

5/894594

Inventors:

Richard Perreault - Amesbury MA

Assignee:

Gould Inc. - Rolling Meadows IL

International Classification:

H01H 8512

US Classification:

337293

Abstract:

A pair of parallel fusible elements is sub-divided, or separated by points of reduced cross-section into two parallel strings of fusible element sections. The pair of fusible elements is supported by a support of electric insulating material including a portion arranged between the pair of fusible elements and extending in a direction longitudinally thereof. The support further includes transverse arms arranged to both sides of the portion of the support that extends in the direction of the pair of fusible elements. These transverse arms are planar and support said planar fusible element sections and consequently the pair of fusible elements. The arms sandwich the planar fusible element sections which are arranged between the arms. If fusible elements of the above kind are connected in parallel into an electric circuit, the fusible elements will fuse sequentially at low currents at one or more points thereof. This process is often referred-to as "triggering".

International Classification:

H01H 8504
H01H 85143

US Classification:

337158

Abstract:

A fuse that includes a tubular member made from insulative material, end block portions made from insulative material, a spanner joining together the end block portions, terminals extending through openings in the end block portions, and a fusible element having ends connected to both of the terminals. Each of the terminals has an internal portion inside the tubular member to which a fusible element is attached, an external portion outside of the tubular member, and a middle portion between the internal and external portions and located within one of the openings of the end block portions.

Assignee:

Gould Inc. - Rolling Meadows IL

International Classification:

H01H 8512

US Classification:

337161

Abstract:

A plurality of ribbon-type fusible elements is arranged in parallel. Each of them includes a plurality of serially arranged points of reduced cross-sectional area. Each of these points is formed by a perforation and two current paths, each to opposite sides of the perforation. Along the plurality of fusible elements, like rungs of a ladder, is arranged a plurality of separate pairs of members of electric insulating material, each covering at least two points of the plurality of points of reduced cross-section. Fastener means project through each of the pairs of insulating members to firmly position the same in relation to the plurality of fusible elements.

Inventors:

Edward J. Knapp - Stratham NH
Richard J. Perreault - Amesbury MA

Assignee:

Gould, Inc. - Rolling Meadows IL

International Classification:

H01H 8514

US Classification:

337248

Abstract:

An electric fuse of the type which has a tubular fuse casing and a solid fuse end terminal telescopically received within the fuse casing is provided with an annular seal which is contained within an annular groove formed in the outer lateral wall of the end terminal. The seal is formed from a settable material which has been injected into the groove through a seal injection opening in the outer end of the end terminal which extends from the axial outer end and into fluid communication with an annular groove provided in the end terminal. A seal material bleed opening is provided in the end terminal which also extends from the axial outer end of the end terminal and into fluid communication with the annular groove. The bleed opening is positioned substantially diametrically opposed to the seal injection opening.

Assignee:

Gould Inc. - Rolling Meadows IL

International Classification:

H01H 8502

US Classification:

337248

Abstract:

Means for affixing the ferrules to a fuse casing include heat resistant elastomeric elements mounted between the rims of a fuse casing and a pair of ferrules, said elements tending to move said pair of ferrules away from the fuse casing in a direction longitudinally thereof. The pair of ferrules having portions engaging circular grooves in said casing and thereby resisting any movement of said pair of ferrules under the forces of said heat resistant elastomeric elements.

US Classification:

337297

Abstract:

A fuse including a fuse casing, an end cap terminal at an end of the casing, a substrate supporting a thin film fusible element thereon, and a disk component that is located at the end of the casing inside of the end cap terminal and has structure that defines a slot and engages an end of the substrate between opposing portions of the structure.

Assignee:

Gould, Inc. - Rolling Meadows IL

International Classification:

H01H 7120

US Classification:

337148

Abstract:

This invention relates to electric fuses meeting the requirements of Underwriter's RK1 classification. It includes a high-current interrupter in the form of a fusible element having serially arranged points of reduced cross-section and a low-current interrupter in the form of a plunger soldered to the high-current interrupter. The plunger is spring biased, and when the solder joint softens, the plunger separates under the action of the spring from the fusible element leaving a large gap between them. The separation of the plunger from the fusible element is allowed to be particularly large on account of the fact that the plunger may be allowed to move into a special fuse cap, known as a cap having a rejection feature as described, for instance, in U. S. Pat. No. 2,943,295 to V. N. Stewart; June 28 1960 for REJECTION TYPE FUSE CLIP and in many other patents.

US Classification:

337244

Abstract:

An externally mounted blown fuse indicator including a housing, a spring-biased plunger, a tungsten restraining wire, two terminals, and a cover, the plunger having a meltable region that is heated by the restraining wire and melts to release the plunger when the fuse blows, the spring engaging a midsection of the plunger, the housing carrying tabs at its ends for engagement with a switch to be activated by the plunger, the spring-biased plunger having greater than 3 ounces force at an extension of 0. 11".
