Abstract
Abstract A multiphase full-wave rectifier assembly comprises positive and negative plates and an electrically insulating body which are stacked together in spaced apart relationship. The positive and negative plates carry first and second sets of three power diodes respectively while the electrically insulating body has three recesses therein. A field diode is mounted in each recess and a respective electrical connector connects one terminal of each field diode with a respective terminal of one of the power diodes in each of the first and second sets. A common electrical connector mounted on the body serves to interconnect the other terminals of the field diodes and also has portions which engage against the bodies of the field diodes to hold the latter in their respective recesses. The common connector is secured to the electrically insulating body by means of rivets which are disposed adjacent the diode-engaging portion of the common connector.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
183 words
A multiphase, full-wave rectifier assembly, comprising a first plate, a second plate substantially parallel to the first plate, first and second sets of diodes carried by the first and second plates respectively, terminals of the first set of diodes extending through holes in the second plate, connector electrically interconnecting said terminals of each diode of the first set with a respective diode of the second set a support structure in the form of an electrically insulating body having recesses therein, a further set of diodes disposed respectively in said recesses, said recesses being shaped so as to hold the diodes of the further set in predetermined relative positions, one of the terminals of each diode of the first set being electrically connected with a respective one of the connectors, and a common connector connecting together the other terminals of the diodes of the further set, wherein the common connector is shaped so that portions thereof overlie said recesses in the electrically insulating body so that the diodes of the further set are retained in said recesses by said portions of the common connector.
Claim 2
Dependent Claim
183 words
A multiphase, full-wave rectifier assembly, comprising a first plate, a second plate substantially parallel to the first plate, first and second sets of diodes carried by the first and second plates respectively, terminals of the first set of diodes extending through holes in the second plate, connector electrically interconnecting said terminals of each diode of the first set with a respective diode of the second set a support structure in the form of an electrically insulating body having recesses therein, a further set of diodes disposed respectively in said recesses, said recesses being shaped so as to hold the diodes of the further set in predetermined relative positions, one of the terminals of each diode of the first set being electrically connected with a respective one of the connectors, and a common connector connecting together the other terminals of the diodes of the further set, wherein the common connector is shaped so that portions thereof overlie said recesses in the electrically insulating body so that the diodes of the further set are retained in said recesses by said portions of the common connector.
Claim 3
Dependent Claim
53 words
An assembly as claimed in claim 1, modified so that instead of portions of the common connector overlying the recesses to retain the diodes of the further set in position, portions of the connector which interconnect the terminals of the first, second and further sets of diodes overlie the recesses for this purpose.
Claim 4
Dependent Claim
52 words
An assembly as claimed in claim 1, wherein each portion of the common connector which overlies a respective one of the recesses is integrally joined to the remainder of the common connector by a respective joining portion to which said other terminal of the respective diode of the further set is attached.
Claim 5
Dependent Claim
21 words
An assembly as claimed in claim 3, wherein the joining portions are co-planar and spaced away from the electrically insulating body.
Claim 6
Dependent Claim
46 words
An assembly as claimed in claim 3 or 4, wherein the common connector is secured to the electrically insulating body by fixing means which are adjacent the joining portions and disposed on the opposite sides of the latter to the recess-overlying portions of the common connector.
