ABSTRACT:
An alternator rectifier assembly for rectifying the output of a poly-phase AC alternator and its method of assembly are disclosed. The alternator assembly comprises a pair of heat sinking DC terminal plate members having a plurality of diode containing recesses with a generally U-shaped circuit board member. The circuit board member is riveted to each of the heat sinking terminal plate members to form a unitary composite body.
The generally U-shaped circuit board member is comprised of a plurality of mutually insulated conductive strips embedded within a plastic material. The ends of the conductors within the circuit board member are exposed for contact with terminals of the diode elements. A plurality of alternator terminal members may be situated within suitably formed recesses or voids within the circuit board member so as to be in contact with the conductive strips and all electrical connections may be soldered by a single pass through a soldering oven. Additional bonding support between the circuit board member and each of the DC terminal plate members is obtained by use of mounting bolts which extend through the unitary composite body. The mounting bolts are provided with knurled shoulders which cooperate with the heads of the bolts to assist the rivets in maintaining the structure in assembled relation.
