Abstract

An electrical connection system for alternating current rectifiers, particularly for use in alternating-current bridge-type rectifiers for motor vehicle generators, in which a portion of an electrical conductor embedded in a circuit board is cooled to a lesser extent than the remainder of the electrical conductor. The lesser cooled portion may have a smaller cross-sectional area than do the remaining portions of the electrical conductor. In the case of an overload on the connection system, the lesser cooled and/or smaller cross-section portion melts through.

Claims

1. In an electrical connection system for an alternating-current rectifier arrangement, in particular for an alternating-current bridge rectifier for a generator which can be used in a motor vehicle having an alternating current rectifier arrangement comprising a plurality of diodes (15, 17), a plurality of phase terminals (12) for receiving a multi-phase alternating current input signal, electrical conductors (22) for connecting the phase terminals with associated terminals of the diodes, and

a substantially plate-like insulating body (23) in which said electrical conductors (22) are embedded,

and including means for cooling at least a portion (28) of the surface of one of said electrical conductors (22) to a lesser extent than the remaining portion of said at least one electrical conductor (22), including

at least one further recess (27) in registration with each of said conductor portions (28) so that each of said conductor portions (28) is in less contact with said insulating body (23) than the remainder of said conductors (22), and

said portion or portions (28) of said conductors (22) protrude from said further recess or recesses (27).

2. The electrical connection system of claim 1, wherein said substantially plate-like insulating body (23) has primary recesses (24, 25, 26) in which portions of said electrical conductors (22) extend for connection with terminals of said diodes (15, 17) and/or said phase terminals (12).

3. The electrical connection system of claim 1 or 2, wherein said portion, or portions (28) of said conductors (22) is or are in the form of a loop.

4. The electrical connection system of claim 1 or 2, wherein said portion or portions (28) of said conductors (22) in registration with said further recess or recesses (27) has a smaller cross-sectional area than the remaining portions of said conductors (22).

5. The electrical connection system of claim 6, wherein said portion or portions (28) of said conductors (22) has a section (28'"'"') of a smaller cross-sectional area than the remaining portions of said conductors (22).

6. The electrical connection system of claim 3, wherein said loop or loops of said portion or portions (28) of said conductors (22) extend from one side of said plate-like insulating body (23), and said diodes (15, 17) are disposed on the opposite side of said plate-like insulating body (23).

7. The electrical connection system of claim 1, wherein said protruding portion or portions (28) of said conductors are disposed on one side of said plate-like insulating body (23), and said diodes (15,17) are disposed on the other side of said plate-like insulating body (23).
