摘要： An electric fuse having plug terminals. The fusible elements are connected to the plug terminal by the intermediary of metal strips having three sections. One section is inserted into the grooves of the plug terminals and conductively connected with the latter. Another section is arranged in a plane parallel to, but spaced from, the plane defined by said first mentioned section. A third section of the metal strips conductively interconnects the first section and the second section thereof. The aforementioned strip, if of sufficient length, greatly increases the flexibility of the fusible-element-and-strip-unit, minimizes the voltage drop across the fuse if the strip is considerably thicker than that of the fusible element of the fuse, and permits an arrangement of the fusible elements within the casing of the fuse that does not depend on the arrangement of the grooves on the axially inner end surfaces of the plug terminals and allows the pulverulent arc-quenching filler to exert a maximal arc-quenching action.

摘要： A time-lag fuse of the type including a fusible element proper, and heat dams formed by strips of sheet metal folded in a direction transversely to the direction of the fusible element proper impeding the axially outer heat flow from said fusible element proper. The fusible element proper has several straight edges extending parallel to the axis of the casing of the fuse. Points of the heat dams engage the inner surface of the casing of the fuse and thus ensure correct positioning of the fusible element proper, i.e. in such a way that its edges extend always parallel to, and are equidistantly spaced from, the axis of the casing. The heat dams engage the inner surface of the casing at discrete points only, to minimize the area of engagement between said heat dams and the inner surface of the casing and to thus minimize direct heat flow from one to the other.

摘要： An electric fuse having a support for helically wound fusible element or elements. The support includes a plurality of rods which are supported at their opposite ends adjacent the fuse end terminal by rod supports each of which is made from a pair of angularly arranged sheet-metal channels. The channels have a U-shaped cross-section and are arranged with their open ends facing the center of the fuse housing. Centrally positioned sections of the channels are flattened to facilitate rigid attachment of the channels to one another. The ends of the rods are received in and attached to interior portions of the U-shaped channels. A sub-assembly comprising the rods, rod supports and the wound fusible elements is pre-assembled and, when placed in a fuse housing, the ends of the channels cooperate with the inside walls of the housing to properly position the entire assembly.

摘要： A blade type fuse whose blades project through the end surfaces of the caps which close the tubular casing. Thus the blade contacts project from the outside of the casing into the inside thereof. There are a plurality of fusible elements inside the casing, all having substantially the same resistance. Some of the fusible elements inside the casing that interconnect the aforementioned blade contacts have a relatively small spacing from the plane defined by the pair of blade contacts. Others of the fusible elements that interconnect the aforementioned blade contacts have a relatively large spacing from the plane defined by the pair of blade contacts. All fusible elements are approximately equally distributed across the cross-section of the casing. This involves for some of the fusible elements a relatively large, and for others of the fusible elements a relatively small, spacing from the plane of the blade contacts to which their ends are attached. To compensate for this difference in spacing the resistance of the connector means is approximately inversely proportional to the spacing of the fusible elements from the plane defined by the pair of blade contacts. Thus the resistance of all fusible elements is equalized, irrespective of their position across the cross-section of the casing of the fuse.
摘要翻译：叶片式熔断器，其叶片突出通过封闭管状壳体的盖的端面。因此，刀片接触件从壳体的外部突出到其内部。壳体内部存在多个可熔元件，全部具有相同的电阻。壳体内的互连上述刀片接触件的一些可熔元件与由一对刀片接触件限定的平面相距较小。互连上述刀片触头的其他可熔元件与由一对刀片触头限定的平面相距较大。所有可熔元件大致均匀分布在套管的横截面上。这涉及一些可熔元件相对较大，并且对于其他可熔元件，与刀片触点的平面相距较小，其端部与其相连。为了补偿这种间隔的差异，连接器装置的电阻大致与可熔元件与由一对叶片触点限定的平面的间隔成反比。因此，所有可熔元件的电阻均衡，不管其在保险丝的外壳的横截面上的位置如何。

摘要： A fuse for elevated circuit voltages having a blown fuse indicator. The fuse is characterized by its great simplicity of design. Virtually all its components, or constituent parts, form a sub-assembly capable of being inserted as a unit into the fuse tube or casing. One terminal of the fuse is formed by a plug contact that defines a heating chamber for heating one end of the restraining wire for the blown fuse indicator above all other points thereof. The other terminal of the fuse is formed by a ferrule, or terminal cap, conductively connected to a perforated metal disk, or metal plate, arranged immediately adjacent thereto. That disk or plate performs four functions, namely (1) to help support insulating rods around which the fusible element is helically wound, (2) to form one of the terminals of the fusible element and of the restraining wire for the blown fuse indicator, and (3) to provide a large aperture through which the fuse is easily filled with arc-quenching filler.

摘要： An electric fuse having a fuse tube or casing into the ends of which plug terminals are plugged. The plug terminals are conductively interconnected by a plurality of fusible elements, the number of which may change depending upon the desired current-carrying capacity of the fuse. Each plug terminal is provided with a recess in the center thereof. Each recess receives an insert member having a wide flange at right angles to the longitudinal axis of the insert member. A small gap is left between the axially outer end surfaces of the pair of flanges and the axially inner end surfaces of the plug terminals. The fusible elements are held in position by radial slots in the aforementioned flanges into which they are inserted, and their ends are bent 90 degrees and inserted into the aforementioned gap. A solder joint is placed in each slot containing a fusible element conductively connecting the bent ends of the fusible elements, the aforementioned flanges and the plug terminals. One or more additional solder joints may be used for connecting the flanges to the plug terminals.

摘要： An electric fuse suitable for motor-starting, i.e. having a considerable time-lag in the range of motor starting currents, and at the same time having a current-limiting action in the high fault current range, characterized by extremely small peak let-through currents and extremely small clearing I.sup.2.multidot. t values. To be more specific, fuses emboyding this invention have considerably smaller maximum peak let-through currents and considerably lower clearing I.sup.2.multidot. t values than Underwriter Laboratories Class RK5 fuses, and meet the maximum acceptable peak let-through current values and clearing I.sup.2.multidot. t values of Underwriter Laboratories Class RK1 fuses. This is achieved by combining specific time-lag means involving a minimum of mass with parallel current paths of greatly increased number and greatly decreased size.

摘要： An electric fuse has helically wound fusible element means which are supported by a mandrel made up of insulating plates. The latter engage grooves provided in terminal plugs of the fuse. The mandrel-forming plates are locked in position inside said grooves by cooperating abutment means. These abutment means are formed by recesses in the mandrel-forming plates, and by projections formed by displaced portions of the metal of which the plug terminals of the fuse are made, which portions enter into said recesses in said mandrel-forming plates and preclude relative movement of the latter and the plug terminals.
