    • Automotive-type fuse for large currents, in which a generally rectangular metal strip (1) of tin-plated zinc, with a central portion shaped to form a conductor (4) of smaller conducting cross section, is provided, at each of its opposite ends, with a circular hole (2, 3) for the screw of an electrical terminal clamp, this hole being surrounded by an annular insert (35, 36) caulked into the strip (1), made of metal, such as copper with tellurium or with beryllium, with a modulus of elasticity and yield-point stress higher than that of zinc, to ensure the stability of the screw clamp, even under vibration, with a clamping pressure greater than the yield-point stress of zinc, by means of the elastic reaction exerted by the ring (35, 36). The central portion (4) of the strip, having the function of a fusible element, is advantageously housed in an opaque plastic containment housing (9, 10) provided with two juxtaposed windows (23, 24), on opposite sides of the fusible element, so that the condition of the fuse can be checked visually, the windows being closed by transparent plastic shields (29, 30).
    • 一种用于大电流的汽车式保险丝,其中一个大致矩形的镀锡锌金属条(1),其中心部分成形为具有较小导电横截面的导体(4),在其相对的每一个处 端部具有用于电气端子夹具的螺钉的圆形孔(2,3),该孔由填充到条带(1)中的环形插入件(35,36)包围,金属制成,例如具有碲的铜 或铍,其弹性模量和屈服点应力高于锌,以确保螺旋夹具的稳定性,即使在振动下,夹紧压力大于锌的屈服点应力,借助于 由环(35,36)施加的弹性反应。 具有可熔元件功能的条的中心部分(4)有利地容纳在设置有可熔元件的相对侧上的两个并列窗口(23,24)的不透明塑料容纳壳体(9,10)中 ,使得可以目视检查保险丝的状态,窗口被透明塑料屏蔽(29,30)封闭。
