发明名称 LATCH AND GUIDE ASSEMBLY FOR A DROPOUT ELECTRICAL FUSE
摘要 A fuse assembly including a pivotally mounted fuse holder having a fusible element disposed therein. The fuse assembly is of the dropout type and adapted for indoor or outdoor use in relatively high voltage circuit applications, such as 34.5 KV. The fuse holder is disposed in the fuse assembly generally vertically with the lower end of the fuse holder being supported by a hinge assembly on which the fuse holder may pivot. The upper end is latched in place by a simplified latch assembly which includes a cantilevered span and locking recess into which a complementary locking and retaining protrusion on the fuse holder may be captured upon the placing of the fuse holder in a normal electrically conductive position. The span is resilient, so as the fuse holder is brought into contact with the latch assembly the span rises vertically under the influence of the previously described protrusion or projection until the protrusion aligns with the recess at which point the recess is lowered onto the top of the fuse so that the recess captures the protrusion. In certain instances, a chargeable kickout spring is disposed on the span so that when the fuse blows the kickout spring will then force upper portions of the fuse holder outwardly away from the upper contact or latch means to a dropout position in which an insulating gap is interposed between the lower and upper contacts of the fuse assembly.
