Abstract

The invention concerns a bridge rectifier for rotary current generators, in particular for supplying the electrical system of motor vehicles. It comprises rectifier diodes and a printed circuit board comprising an insulator (23) basically designed in the shape of a plate, in which multiple connection conductors (24) are embedded between the diodes of the rectifier bridges, whereby sections of these connection conductors are designed to be bent extending out of the insulator and as fuses (25) that melt in case of electrical overload. In order to achieve the smallest possible tolerances for operation of the fuses, each of the fuses (25) is formed out of two conductor ends (24a)-bent to the outside-of the connection conductors (24) and a fuse element (29) connected with them that bridges the conductor ends.

Claims

1. Bridge rectifier (15) for rotary current generators (11), in particular for supplying the electrical system of motor vehicles, comprising rectifier diodes (17,18) and a printed circuit board comprising an insulator (23) basically designed in the shape of a plate, in which multiple connection conductors (24) are embedded between the diodes of the rectifier bridges (12, 13, 14), whereby sections of these connection conductors extend out of the insulator and are designed as fuses (25) that melt in case of electrical overload, characterized in that each of the fuses (25) is formed out of two conductor ends (24a) bent to the outside and a fuse element (29) connected to them that bridges the conductor ends.

2. Bridge rectifier according to claim 1, characterized in that the fuse element (29) is a metal strip, the ends (29a) of which are electrically connected with the conductor ends (24a).

3. Bridge rectifier according to claim 1 or 2, characterized in that the fuse element (29) is connected with the conductor ends (24a) using clamps.

4. Bridge rectifier according to claim 2, characterized in that the fuse element (29) is soldered or welded to flattened end sections (24b) of connection conductors (24) consisting of round wire.

5. Bridge rectifier according to one of the claims 1 through 4, characterized in that each of the fuse elements (29) is surrounded by a container.

6. Bridge rectifier according to claim 5, characterized in that the containers (30) attached to the insulators (23) designed in the shape of a plate are preferably glued.

7. Bridge rectifier according to claim 5, characterized in that the containers (30) are filled with silica sand.
