FULL WAVE RECTIFIER ASSEMBLY,PARTICULARLY FOR COMBINATION WITH AUTOMOTIVE TYPE ALTERNATORS

摘要

A rectifier assembly 37 for an A.C. generator 20, e.g. of an automobile, comprises two sheetmetal cooling elements 46, 47 mounting respective sets of positive and negative diodes 48 ... 50 and 53... 55 whose terminals, e.g. 83, extend into hollow-rivet-like parts 75 ... 80 inserted into an insulating plate 74, connection lines, e.g. wires 88 ... 90, also being connected to the parts 75 ... 80. Such wires lead to the generator stator winding phases V, W, U, and three field diodes 56 ... 58 are connected to these phases and to a metal strip 84. The elements have sheet-metal strips (62, 621), Fig. 6, whose tapered ends 98 are twisted to retain the insulating plate 74 in position, whilst in another embodiment they are riveted. The diodes are pressed into apertures (63), Fig. 5 in the elements, one, 47, of which is screwed directly to bosses 39 on the bearing-plate 36 whilst the other, 46, is screwed to shortened bosses via insulated eyelets 65, 66.
