    Abstract: A high-current current-limiting fuse comprises an aluminum plate containing two spaced-apart notches extending transversely of the central longitudinal axis of the plate from opposite lateral edges of the plate to points near said axis, thereby dividing the plate into two massive tang portions spaced apart along said axis and a restricted neck portion interconnecting the tang portions. The tang portions constitute fuse terminals, and the neck portion constitutes fusible conducting means for carrying current between the tang portions and for melting in response to overcurrents. The neck portion is integral with the tang portions, and the junctions between the neck portions and the tang portions are free of solder. A housing of insulating material surrounds the neck portion and comprises plates of insulating material at opposite faces of the aluminum plate and portions of insulating material extending into the notches. The insulating plates are secured to said tang portions and to each other, thereby effectively preventing motion of the tang portions relative to each other.

    Abstract translation: 大电流限流熔断器包括铝板，该铝板包含两个间隔开的槽口，其横向于板的中心纵向轴线从板的相对侧边缘延伸到靠近所述轴线的点，从而将板分成两个块状柄部 沿着所述轴线间隔开，并且限制颈部部分互相连接柄脚部分。 舌部构成熔丝端子，并且颈部部分构成用于承载柄部之间的电流并响应于过电流而熔化的可熔导电装置。 颈部与柄脚部分成一体，并且颈部和脚部之间的接合处没有焊料。 绝缘材料的壳体围绕颈部并且包括在铝板的相对面处的绝缘材料的板和延伸到凹口中的绝缘材料的部分。 绝缘板固定到所述柄部和彼此上，从而有效地防止脚部相对于彼此的运动。
