Abstract

PURPOSE: To eliminate the need for using a connection bolt in the direction of an axial line by fixing a support plate that is bent by a screw bolt which is directed outwards in the radial direction fixed directly to a positive cooling plate. CONSTITUTION: A leg part 18b of a support plate 13 that is directed outward in the radial direction is riveted to a forward cooling plate 11 by two rivets 20 that are arranged at an interval. In this case, a leg part 18a of a support plate 18 that is bent toward the rear, while supporting a screw bolt 17 a positive connection terminal 16, projects over the outer edge part of a rear cooling plate 12. The leg part 18a is accommodated in a plastic member 21, and the plastic member is mounted to the outer edge part of a printed wiring board 15, so that the leg part 18a of the support plate 18 can be supported for the outer edge part 12a of the rear cooling plate 12. As a result of this, the need for the connection bolt in the direction of an axial line and guiding vibration stresses given to an insulation terminal to two cooling plates is eliminated, hence obtaining a simple and reliable rectifying device.

PRIOR ART In the configuration of a three-phase alternator alternator known from European patent A2-0199504, the connection terminals of the rectifier arranged in the generator casing, designated B+ according to the DIN standard, are arranged radially outwards. At that time, the connecting bolt is first inserted into the positive cooling plate of the rectifier in the axial direction and screwed to the generator casing and the joint angle member, and this joint angle member is bent As a support plate it supports threaded bolts pointing radially outward. In this case, the connecting angle part, with the exception of the threaded bolt, is encapsulated by an insulating plastic part, which protects the connection terminal from the generator housing which is at ground potential. Radial terminals of this type are used in cases where later installation in the vehicle is difficult or impossible with axial terminals, for example due to lack of space on the generator end face. .

This solution requires a large number of parts to be produced separately and, furthermore, when installing the rectifier in the generator, a radially outwardly directed threaded bolt is later installed on the connecting bolt. This has the disadvantage that, in order to attach the joint angle part, the axial connecting bolt must first be inserted.

Advantages of the invention A rectifying device according to the invention having the features of claim 1 comprises:
The direct fastening of the support plate with radially outwardly directed threaded bolts to the positive cooling plate has the advantage that axial connection bolts are omitted. As a further advantage, a configuration is shown in which a printed circuit board arranged between two cooling plates of a rectifying device is used at the same time to support the support plate and the radial threaded bolts in an insulating manner. This makes it possible to conduct torsional forces and vibrational stresses, which may act on the B-connection terminals, to both cooling plates of the rectifier. This can be avoided by using a plastic member to support the outer edge of the rear cooling plate.
