Abstract

Bus strips of steel or brass, rivetted where necessary to the brush holder and to a flat plate member integral therewith serve to connect the terminals of the voltage regulator mounted on the flat plate to the brush holder and to terminals for positive and negative voltage, the exicitor winding of a generator and the D+ and D- terminals. The bus strips are soldered or welded to the terminals they connect so as to provide reliable connections for the life of the device. The negative terminal connection includes a bushing in a mounting eye of the flat plate and the positive terminal is provided as a pressure contact.

Claims

1. A voltage regulator for a generator suitable for vehicular service having its circuit components contained within a casing similar to a transistor casing, and being combined on a common base member with a brush holder and further being provided with connections at least for a negative lead, a generator exciter winding lead and a positive lead, further comprising the improvement which consists in that:

said casing (11) is mounted on a flat plate (13) having circularly cylindrical mounting eyes (15) and formed integrally with and adjacent to the brush holder (19);

bus strips are provided for electrical connection of terminals of the voltage regulator and brushholder;

a metallic bushing (39) is set within one of said eyes and connects with said negative voltage supply bus strip (27), and

said positive voltage supply bus strip (27) connects with a terminal in the form of a pressure contact (40).

2. A voltage regulator as defined in claim 1 in which said bus strips (25-29) are at least in part externally applied to said brush holder (19).

3. A voltage regulator as defined in claim 2 in which said bus strips (25-29) are made of steel.

4. A voltage regulator as defined in claim 2 in which said bus strips (25-29) are made of brass.

5. A voltage regulator as defined in claim 1 in which said bus strips (25-29) are welded to the terminals to which they connect.

6. A voltage regulator as defined in claim 1 in which said bus strips (25-29) are soldered to the terminals to which they connect.

7. A voltage regulator as defined in claim 1 in which said bushing (39) has a length equal to the axial dimension of the eye (15) in which it is inserted.
