Abstract: An improved cable assembly for electrical overload protection, the cable assembly having a first cable, a second cable, a fusible link, and a protective housing. The first and second cables have a protective covering and an end portion extending past the protective covering. The fusible link is located between the first and second cables such that the end portions of the cables are electrically connected to opposing ends of the fusible link. The protective housing encases a portion of the fusible link, with an intermediate section of the protective housing being spaced away from a portion of the fusible link to form a cavity. The protective housing also engages a portion of the first and second cables to form a rigid interconnecting housing around the fusible link and portions of the first and second cables.

Abstract: A fuse element having a substantially planar strip formed of an electrically conductive metal having a central portion and opposite end portions. The central portion is provided with a plurality of diamond-shaped perforations. The perforations form a plurality of branches that define a plurality of elongated, narrowed electrical pathways across the central portion. The joints where the branches meet form the weak spots for the fuse element. The central portion of the fuse element is encased in a material that is electrically non-conducting and heat conducting. The material, a ceramic, for example, is injection molded in and around the perforations to substantially completely encase the central portion of the fuse element.

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.

Abstract: A multi-element high-voltage fuse comprises a plurality of similar fuse elements connected in parallel, each element being a strip of fusible material having a plurality of first portions of reduced cross-section spaced along its length and, between each mutually adjacent pair of said first portions, a plurality of shorter second portions of reduced cross-section. Under shortcircuit conditions, substantially all the first and second portions of all the elements fuse simultaneously. Under low overload conditions, the elements fuse one at a time, at their longer first portions only, but the conditions are such that multiple arcing occurs, at substantially all these longer first portions, leading to safe fuse operation, at lower values of overcurrent than in conventional designs; and since the longer first portions are much less numerous than the shorter second portions they have relatively little effect on the overall resistance of the fuse and thus on its current carrying capacity. Conversely, fewer parallel elements are required to achieve a given minimum breaking current, since a lower current density per element suffices to produce multiple arcing. Thus, for a given minimum breaking current, the fuse may be more compact and robust than hitherto. In general, each element should contain about one of the longer second portions per kilovolt of the voltage rating of the fuse, for safe operation of the fuse under low overload conditions.
Abstract translation: 多元件高压熔断器包括并联连接的多个类似的熔丝元件,每个元件是可熔材料条,其具有多个沿其长度间隔开的截面减小的第一部分,并且在每个彼此相邻的一对 所述第一部分,具有减小横截面的多个较短的第二部分。 在短路条件下,所有元件的基本上所有的第一和第二部分同时熔断。 在低过载条件下,这些元件一次只能在其较长的第一部分熔断,但条件是这样的情况会导致多次电弧发生,在几乎所有这些较长的第一部分,导致安全的熔断器操作, 在传统设计中; 并且由于较长的第一部分比较短的第二部分多得多,所以它们对熔断器的总电阻以及因此对其承载能力的影响相对较小。 相反,实现给定的最小断开电流需要更少的并联元件,因为每个元件的较低电流密度足以产生多次电弧。 因此,对于给定的最小分断电流,保险丝可能比迄今为止更紧凑和鲁棒。 通常,每个元件应包含每千伏保险丝额定电压的较长的第二部分中的一个,以在低过载条件下保险丝的安全运行。
