<p>1294112 Rectifier assemblies JOSEPH LUCAS (INDUSTRIES) Ltd 23 March 1970 [17 April 1969] 19578/69 Heading H1K A full-wave rectifier assembly in which two groups of diodes are mounted on respective mutually isolated terminal plates 31, 32, a number of mutually isolated phase plates such as 42 equal to the number of phases in the A.C. supply being rectified is formed by dividing a single original plate around part of which has been moulded an insulating body 27 used to support the phase plates relative to a support bolt 21, which also supports the terminal plates 31, 32. Leads interconnect the free terminals of the diodes on the terminal plates with the corresponding phase plates. In the arrangement shown additional diodes are provided on a subsidiary terminal plate 33 which, when the assembly is in use in a road vehicle, supplies an output for operating an indicator lamp. Each phase plate such as 42 may have separate fingers (42a, 42b, 42c), Fig. 3 (not shown), to which different diodes are connected by leads, thereby minimizing the risk of leads snapping due to vibration in use.</p> |
