摘要： A Full-Range fuse element assembly includes an insulative former having opposite first and second ends and electrically conducting connectors coupled to ends of the former. A plurality of fuse elements extend between the first connector and the second connector about the insulative former, and each of the fuse elements include a low current interrupting fuse element portion extending from the first connector and a high current limiting fuse element portion extending from the second connector. An insulative sleeve surrounds each of the low current interrupting fuse element portions, and each sleeve includes an end adjacent a respective one of the high current limiting fuse element portions. Each of the low current interrupting fuse element portions includes a weak spot located proximate the second end of a respective one of the sleeves.

摘要： A fuse includes a tube, a pair of blade terminals projecting from opposite ends of the tube, at least one fuse element disposed in the tube and electrically coupled between the terminals, and a pair of metallic end caps disposed on opposite ends of the tube. Electrically insulative elements are disposed between the end caps and the terminals. The tube is filled with an arc-quenching material inserted through a fill hole that is plugged by a plastic drive rivet. Each terminal is attached to a metallic end plate by means of a staking tang inserted into a slot of the end plate, and by means of a separate solder joint. Each insulative element includes an axial sleeve through which a respective terminal extends for a part of its length. The fuse element comprises a one-piece metal element bent to form a pair of parallel, superimposed strips divided into sections by means of fusible weak points. The metal element also includes bridge elements which join sections of one strip to respective sections of the other strip, the bridges themselves being non-interconnected. End-most sections of one strip are fixedly joined to respective end-most sections of the other strip to define tabs for electrically connecting the fuse element to a circuit.
摘要翻译：保险丝包括管，从管的相对端突出的一对刀片端子，设置在管中并电耦合在端子之间的至少一个熔丝元件以及设置在管的相对端上的一对金属端盖。电绝缘元件设置在端盖和端子之间。该管充满了通过填充孔插入的灭弧材料，该填充孔被塑料驱动铆钉堵塞。每个端子通过插入到端板的槽中的桩脚并且通过单独的焊接接头附接到金属端板。每个绝缘元件包括轴向套筒，相应的端子通过该套筒延伸其长度的一部分。保险丝元件包括一体式金属元件，弯曲成通过可熔弱点形成一对平行的，叠加的条带，分成多个部分。金属元件还包括将一个条带的部分连接到另一条带的相应部分的桥接元件，桥接件本身是非互连的。一个条带的最终部分固定地连接到另一条带的相应最终部分，以限定用于将熔丝元件电连接到电路的突片。

摘要： A fuse circuit (11) having a plurality of terminals (22, 23) provided on a common joint plate (21) and a fuse circuit (11′) having a plurality of terminals (22′, 23′) provided on a common joint plate (21′) are incorporated into a housing (12), thereby constituting a fuse link assembly (10). The plurality of fuse circuits (11, 11′) are provided with circuit connection portions (27, 27′) which share a power input portion. The fuse circuits (11, 11′) are incorporated into the housing (12) in parallel. As a result, the number of circuits is increased, by means of only enlargement of widthwise direction Y which is easy to increase while enlargement of longitudinal direction X stemming from packaging of circuits is minimized.
