摘要： An electrical interruption device is disclosed in which an overcurrent protective device is provided to interrupt electric current flow on a sustained overcurrent current occurring. The overcurrent protective device is characterized by a plunger which is held in tension against the force of a spring by a low temperature solder, and further in which a sleeve of insulating material, such as silicone, is provided about the plunger. Preferably, the overcurrent protective device includes a housing, with the plunger disposed in the housing and having one end extending therefrom to provide electric communication with the remainder of the electric circuit. The sleeve of insulating material preferably being located about the end of the plunger which extends from the housing. On a predetermined condition causing the solder to melt, the plunger is released and under the force of the spring is moved to a position retracted within the sleeve, interrupting the current flow. Advantageously, the overcurrent protective device may be used together with pulverulent arc quenching material. The sleeve acts to isolate the pulverulent arc quenching material from the plunger and prevent its interference with the plunger as it is moved under the force of the spring.

摘要： An electrical interruption device is disclosed in which a space efficient spiral spring activates current interruption. The spring is characterized by coils which wind continuously about and approach a central axis, with successive coils of the spring having reduced radius to pass axially through the center of an outwardly adjacent coil. The spring may further be made to assume a flat condition with the spring coils lying flat, nesting interposed between adjacent coils. Advantageously, the spiral spring is conical in shape and is tensioned in a reverse loaded configuration wherein the coils of one end of the spring are pulled axially inward, through and past the coils of other end. Preferably the reverse loaded conical spring forms part of a thermally sensitive device which includes a housing having disposed therein a plunger which is in a biased relationship with the spring. The plunger extends beyond the housing to provide electrical communication with the remainder of the electric circuit, and is held in place against the force of the spring by a meltable solder. On a predetermined condition causing the solder to melt, the plunger is released, whereby it is moved by the force of the spring into the housing and out of electric communication with the remainder of the electric circuit.
摘要翻译：公开了一种电气中断装置，其中空间有效的螺旋弹簧激活电流中断。弹簧的特征在于绕着中心轴线连续地卷绕的线圈，弹簧的连续线圈具有减小的半径以轴向通过向外相邻的线圈的中心。弹簧可以进一步制成平坦的状态，弹簧圈平放，嵌套在相邻线圈之间。有利的是，螺旋弹簧的形状是圆锥形的，并且以反向加载的形式被张紧，其中弹簧的一端的线圈被轴向地向内拉动并穿过另一端的线圈。优选地，反向装载的锥形弹簧形成热敏装置的一部分，其包括壳体，其中设置有与弹簧处于偏置关系的柱塞。柱塞延伸超过壳体以提供与电路的其余部分的电连通，并且通过可熔化的焊料抵抗弹簧的力保持就位。在导致焊料熔化的预定条件下，柱塞被释放，由此弹簧的力被移动到壳体中，并与电路的其余部分脱离电通信。
